Function MO - Monitor Control (Control User)

The Monitor Control function allows you to monitor and manipulate the status of the running Com-plete session. It provides information about Com-plete subtasks, buffers, terminals, users, etc. In addition, Com-plete operator commands can be entered directly.

When you invoke the MO function, the following menu is displayed:

You can select any of the MO subfunctions by entering the appropriate function code in the Select Function field and, optionally, an operand in the Operand field.

You can also enter Com-plete operator commands in the Operator Command field of this and any other screen of the MO function. The Monitor function then directly switches to the CM subfunction. For available operator commands, see the Com-plete Operator Commands documentation.

All subfunction screens have the same PF key assignments:

PF key Function
PF3/CLEAR Leave the Monitor Function
PF7 Scroll up
PF8 Scroll back
PF10 Scroll left
PF11 Scroll right
ENTER Refresh screen

A direct switch to other subfunction displays is invoked by entering the appropriate function code.

The line display for a buffer pool only contains information if the buffer pool is active. If it is not possible to display the information, a message indicating the reason is displayed in the line, for example: Deleted, as in the above example.

Meaning of the information items according to column heading:

Heading Meaning
No. Number of the buffer pool relative to the time of creation.
FBP-Name Name of the buffer pool as specified at creation time via the DESC= parameter of the CMFBPM BPCREATE macro.
ANY* Storage acquired above (if supported) or below the 16 MB line.
BELOW* Storage acquired below the 16 MB line.
Other Locations used DS for Dataspace; 64BIT for storage above the bar.
Gets Total GETs for all subpools in this buffer pool.
Fails Total FAILs for all subpools in this buffer pool.
Exp Total Expansions for all subpools in this buffer pool.
Cnt Total Contractions for all subpools in this buffer pool.

* Each of these columns may contain 2 values: the total number of subpools created for this buffer pool, and the total amount of storage used by all subpools in this buffer pool. These columns represent the data areas from where the stoirage is acquired for a subpool. This is a direct correlation of the LOC= parameter as specified in the CMFBPM SPCREATE macro when creating a subpool.

You can select a specific buffer pool to display a breakdown of subpool statistics: enter the buffer pool name or its relative number in theOperand field and press ENTER.

If a specific buffer pool is selected using the Operand field, there are two forms in which the buffer pool statistics can be viewed. You can toggle between the two forms using PF10 and PF11, while PF7 and PF8 can be used to scroll through the displays when there is more than one screen page of information. Where a numeric value exceeds the length of the area available to display it, it will be presented in K (value/1024) or M (value/1024/1024).

If you select a specific buffer pool, the following screen is displayed:

Meanings of the various column headings:

Heading Meaning
Buffer Pool Name This is the name of the buffer pool for which statistics are currently being displayed. This will only occur on the first screen display for a buffer pool if more than one screen is required to display all subpools in the buffer pool.
Subpool This is the name of the subpool, which is an eight character indicator as to what the subpool is for. In the example above, the subpools are for general use and therefore have the same subpool name. In other allocated buffer pools, you will find differing names.
No This is the number of the subpool in question. When subpools are allocated, they are given a sequential number which is one greater than the previously allocated subpool.
Loc This indicates where the buffer elements are allocated. There are three possible values that can be displayed here:
BELOW storage is allocated below the 16 MB line.
ANY Storage is allocated above the 16 MB line.
DS Storage is allocated in a Data Space.
Esize This is a number indicating the size of the elements allocated in the subpool.
Used(%) This shows the number of elements in use in the subpool along with the percentage of the currently allocated elements thta this figure represents.
Max Used This shows the maximum number of elements ever used in the subpool along with the percentage of the base allocation for the subpool. Note that if the subpool has ever expanded, these values will not be displayed.
Base This is the initial number of elements allocated for subpool when it was built.
Curr This indicates the current number of elements allocated for the subpool. Note that this will equal the number given for 'Base' if there are no current expansions of a subpool.
High This contains the highest number of elements ever allocated for the subpool.
Gets This is the number of get requests that have been made against the subpool.
Fails This is the number of get requests made against the subpool which have failed. A failure can occur for the following reasons:
1 The base allocation for the subpool is in use and the subpool does not allow expansions.
2 The current allocation for the subpool is in use and the subpool has expanded as often as is allowed.
3 The current allocation for the subpool is in use and an attempted expansion of the subpool failed. This could occur due to a shortage of storage in the region or partition.
Exp This is the number of times that the subpool has expanded. If it contains '***', it indicates that the subpool has expanded more than 999 times. While expansion can be a normal part of the day, it is expensive and therefore subpools should be defined such that expansions are kept to a minimum.
Cnt This is the number of times the subpool has contracted. This may also contain '***' indicating that contraction has occurred more than 999 times. Again, this is an indication that this subpool is trashing, as expansions and contractions are occurring regularly. In this case, the parameters causing the subpool to be built should be reviewed. Also, if expansions are occurring and no contractions are subsequently occurring, it indicates that the initial allocation for the subpool is not sufficient and should be changed or that elements of the subpool are not being freed for some reason.

If you press PF11 (scroll right) on a display for a specific buffer pool, the following screen is displayed.

        Command:

The various sub headings on this display, which are the same as those on the first display, have the same meaning. The difference here is that the figure presented is in Kbytes. The values provided only related to the actual buffer subpool storage and do not include the storage required to maintain the buffer pool and it's subpools. For more information on this, please refer to Resource Usage and Estimates in the System Programming documentation.

Buffer % Used

The values in these columns provide an overview as to how much of the actual buffer is being used when it is obtaines. That is to say, even though a request may be satisfied by a buffer with a length of 64 bytes, it may only require 32 bytes; however, it will still have 64 bytes reserved for it. The intention is that the buffer subpools can be tuned based on the usage of the buffer pools and perhaps additional subpools defined and/or current allocations changed.

6 ranges are presented (R1 to R6). The figures below these ranges indicate the percentage of overall requests which only used that amount of the buffer. Where 100% of requests fall into a specific range, '**' will be seen as the range. The various ranges represent the following usages of the buffer. Note that if the buffer is utilised 100% it will not be reflected in any of the ranges.

R1 less than 50% of the buffer used.
R2 50% to 59% of the buffer used.
R3 60% to 69% of the buffer used.
R4 70% to 79% of the buffer used.
R5 80% to 89% of the buffer used.
R6 90% to 99% of the buffer used.

The figures should be used to eliminate major wastage of storage. For example, if a buffer subpool consistently has 100% (ie '**') in the first range, it indicates that all requests satisfied by this subpool could actually be satisfied with an elements size which is half the size or possibly less, of the current element size defined for the subpool. As all requests in this category are satisified in this way, the element size of the subpool should simply be halved. In a case where 50% of the requests satisfied are in the 'R1' category, another buffer subpool with an element size half the currently defined size should be allocated. The number of elements for the new subpool should be half the number allocated for the current subpool while the scurrent subpools allocation should also be halved.

While this method could be used to fine tune the allocation of subpools and the sizes allocated, the storage savings must be weighed against the time spent fune tuning the system. Also, a change in system load can "undo" the newly tuned subpools and would require that the process be repeated.

FL Subfunction

The FL subfunction can be used to find out from which library in the COMPLIB chain a given program is loaded from. The name of the program must be entered in the operand field. A load count of 0 does not signify that the module has never been loaded from the library, but that no thread task has done so.

FP Subfunction

The FP subfunction can be used to find out where a given program is loaded from. The name of the program must be entered in the operand field.

The search for the load module is performed in the same sequence Com-plete uses when loading a program requested by the terminal operator or by an application:

  • resident programs

  • LPA/ELPA (OS systems) / SVA and partition GETVIS area (z/VSE systems)

  • program lookaside buffer

  • COMPLIB load library chain.

Depending on where the program is first found, the FP subfunction results in the screen of the RP, IP, or OP subfunction being displayed. When the program is first found in the LPA/ELPA (OS) or SVA/partition GETVIS area (z/VSE), this fact is indicated by an appropriate message in the top line of the screen.

IP Subfunction

The IP subfunction displays statistics on the programs in the lookaside buffer. Its contents can be specified using the PGMLOOKASIDE sysparm.

For every program in the buffer, the display contains the name and size of the program and the number of loads:

OP Subfunction

The OP subfunction displays the contents of the instorage program directory (ISD)

To avoid searching for a load module each time it is being loaded, Com-plete keeps the BLDL / LOADLIST information for the most recently used load modules in an instorage directory.

The size (number of entries) of the ISD can be specified using the PROGRAMISD sysparm.

For each load module in the ISD, the display contains the name and number of loads. If the number of loads is not indicated for a module, the appropriate load module has been requested, but does not exist.

         Command:
Grp Name

This is the name of the group for which the information is being displayed.

Status

This is the status of the task. The task group may be Active, Quiescing or Dormant. When a task group is active, Com-plete can allocate and deallocate tasks from that group at will. When the group is quiescing, any tasks that have previously been allocated will remain available until they are deallocated by all users using them. When the last task is deallocated, the task group will have deemed to be quiesced and the control block will be marked as dormant.

Pri

This is the priority of the tasks associated with the task group. Under z/OS and Hitachi systems, this reflects the actual operating system priority assigned to the tasks.

Use Counts - Cur

This is the number of users with the tasks currently allocated from the task group.

Use Counts - High

This reflects the highest number of users which had tasks allocated in this task group at any one time since the group was initialised.

Tasks - Act

This is the number of tasks which the installation wishes to have defined within the task group.

Tasks - Hig

This is the highest number of tasks active at any one time since the task group was initialised

Tasks - All

This is the number of tasks actually allocated for the task group. This may differ from the number of tasks active as when the number of tasks is to be reduced, the tasks must first be quiesced in order to let current users of the tasks to be deleted, to finish their work. These tasks and their associated resources will only be physically deallocated and disappear from this count when the last user deallocates the task and it becomes dormant. Tasks can be added or removed from task groups using the 'TASKS' operator command.

Q Counts

Each task group has four work queues associated with it, each queue representing a priority from 0 to 3. The total values are provided for all queues in this display; if values for each individual display are required use the QO function. Because these values are changing as they are being collected, there is a very slight possibility that inconsistencies may appear in the figures displayed. For this reason, these figures must be taken as a good indication rather than absolute values.

Q Counts - Curr

This is the number of users currently on queues associated with this task group.

Queue Counts - High

This is the sum total of the highest number of users which were on each queue associated with this task group at any one time.

PL (Task ("Processor") List) Subfunction

This function will display a list of all tasks in the requested task group and their current status. If no task group operand is provided, the tasks for all task groups are displayed. The following display is a sample of what will be displayed.

         Command:
Grp Name

This is the name of the task group of which the task in question is a member.

Status

This reflects the current status of the task. The status is a combination of two state indicators separated by a dash ('-'). The primary state indicator, which is the letter preceding the dash, indicates whether the task is Active, Quiescing or Dormant by the letters A, Q and D respectively. Active in this sense indicates that the task is available to do work. When it is quiescing, it will remain active long enough to finish any work which has been started by the task while dormant tasks cannot be used and will have no secondary state associated with them. The secondary states which may occur are as follows:

'Wait' Status

This indicates that the task is waiting. In this state, the task is waiting on new work or on events requested by programs running in threads associated with it.

'Run' Status

This indicates that the task is currently running a user program.

'Disp' Status

This indicates that the task is going through it's dispatching cycle either finishing off old work or looking for new work.

Use Counts - Curr

This is the current use count for the task. The use count includes the current user of the task, any users for whom a wait was issued on the task and any users with an affinity for this task.

Use Counts - High

This reflects the highest ever use count experienced for the task since it was initialised.

Wait Counts - Curr

This is the current wait count for the task. This reflects the number of events upon which the task is waiting and includes two standard events, those being that work has been queued to the task group work queues or to the task's own work queue.

Wait Counts - High

This reflects the highest ever wait count experienced for the task since it was initialised.

Last Op

This is the last Com-plete op which was issued under control of the task.

Current/Last Active Userid

This is the userid of the current user active under control of the task or the last user to be active under control of the task if it has a secondary status of 'wait'. This may be blank in systems where logon is not forced and will generally be blank for ULOG sessions where the user is logging on.

Current/Last Active Program

This is the name of the program currently active under control of the task, or the last program to be active under control of the task if it has a secondary status of 'wait'. If the task has never been used, this will be blank, however, once it has been used, this will always contain a value.

Current/Last Active Tid..

This is the tid of the current TIB active under control of the task, or the last TIB to be active under control of the task if it has a secondary status of 'wait'. If the task has never been used, this will be blank, however, once it has been used, this will always contain a value.

Current/Last Active L

This is the level number on which the user currently active under control of the task, or the last user to be active under control of the task if it has a secondary status of 'wait', is running. If the task has never been used, this will be blank, however, once it has been used, this will always contain a value. Level '0' will be displayed for a non-COM-PASS user, for a COM-PASS user who is running a program while something is stacked on all possible levels and for certain programs which must run on level 0 such as ULOG.

Time

When the task has a secondary status of 'Run', this will reflect the time in seconds that this user has spent under control of the task.

Queue Name

This is the 16 character name of the queue for which details are provided. The first six queues are the standard system queues used by Com-plete. Following this, each of the task group's queues will follow. The first eight characters of these queue names will contain the task group name while the second eight characters indicates their purpose within the task group.

Each task group has one common work queue upon which the work is queued that does not have an affinity to a particular TCB within the group, i.e. that can be executed on any TCB in the group. In addition, each task within the group will have its own work queue with the identifier 'TASK-Q' associated with it. These queues are used for work which is associated with a particular task.

Current in Queue

This is the number of tibs currently in the queue.

HWM in Queue

This is the maximum number of tibs that was ever at one time in the queue.

Total in Queue

This is the total number of tibs which were ever queued here.

Time in Queue (LAST)

This is the time in milliseconds the last tib spent in the queue.

Time in Queue (Average)

This is average amount of time in milliseconds a tib spent in the queue.

Time in Queue (HWM)

This is longest time a tib ever spent in this queue.

Time of HWM

Shows when the HWM for 'Time in Queue' was taken.

Last Deq

If there are currently tibs in the queue, this means either the time when the tib was put in an empty queue, or the time when an already waiting predecessor was taken (dequeued) from the queue.

RA Subfunction

This function displays performance critical statistics from the Com-plete Roll Subsystem. These statistics should be monitored on a regular basis to check if changes ara necessary. The Roll Activities display is as follows:

         Command:

The information items are explained on the following pages.

Item Meaning
Avg Rsize Average size of thread image that has been rolled up to this point.
Avg Csize Average size of the thread image after Com-plete compression has been performed and is the average of the actual amount of data which the roll subsystem will have rolled.
Out Total Total number of rollout requests.
In Total Total number of rollin requests.

An additional display is available by pressing PF11 from the first RA screen, which presents an overview of the size of the images being rolled out, the number of such images and the percentage of the total. Each rollout size is rounded to the nearest 4k, therefore for every 4k slot (8K, 12K, 16K......1024K) a count is kept of the number of images of each size. To keep the display simple, where a size has not been used, it is not displayed. Therefore, the display consists of an entry for each size which has actually been rolled, the number of times that size was rolled and the percentage of the total rollouts in the system. This display enables you to determine what the load on the roll subsystem is and to determine the subpool sizes and number of elements required for a Fixed Roll Buffer Pool. The following is an example of this display:

        Command: 
Name

This is the name of the subgroup to which the line of statistics relates.

Above

This is the amount of storage each thread in the subgroup has available above the line.

Below

This is the amount of storage each thread in the subgroup has available below the line.

Threads - Def'd

This is the number of threads which the installation wishes to have defined within the thread subgroup.

Threads - Alloc

This is the number of threads actually allocated for the thread subgroup. This may differ from the number of threads defined as when the number of threads is to be reduced, the threads must first be quiesced in order to let current users of the threads to be deleted, finished their work. These threads will only be physically deallocated and disappear from this count when the last user deallocates the thread and the thread becomes dormant.

Note: Com-plete does not currently provide a mechanism to change the number of threads defined within a thread subgroup dynamically, therefore the values given for 'Threads' should always be identical.

HWM Above/Below

This shows the highest amount of thread storage used above/below the line in the thread group.

Use Counts - Curr

This is the number of users with the threads currently allocated from the thread subgroup.

Note that users which are rolled out and relocatible are not included in any subgroup

Use Counts - High

This reflects the highest number of users which had threads allocated in this subgroup at any one time since the subgroup was initialised.

Wait Counts - Curr

This is the number of users currently waiting for a thread of the thread subgroup to become available. Users waiting for a distinct thread due to an affinity are not included in this number.

Wait Counts - High

This reflects the highest number of users which were waiting for a thread of the thread subgroup to become available at any one time since the subgroup was initialised

CPU

This is the number of CPU seconds which a user program using the thread subgroup in question can use between roll outs before being terminated abnormally by Com-plete. If the word 'none' appears for this field, it indicates that no CPU time was requested in the Sysparms. Note that Com-plete still sets a nominal time of 24 CPU hours when no CPU timing is requested by the user. This is required for the calculation of CPU time statistics.

Real

This is wall clock time which is set for each thread in the subgroup. If a user program occupies the thread without doing a rollout for longer than this time, a message is issued to the operator console. This message will be repeated every 30 seconds after the first message if the user program does not give up the thread. If the word 'none' appears in this field, it indicates that Com-plete is not calculating the length of time user programs are in a thread for threads in this subgroup.

K

This is the key in which threads in the subgroup are set when a new program starts in one of the threads. If an absolute key number is displayed, it indicates that all threads in the subgroup get that key. If the letter 'M' is displayed, it indicates that the keys for threads within the subgroup are mixed within the range of user protect keys available from the operating system.

SO Subfunction

This subfunction displays an overview of Servers active in Com-plete.

         Command:
Grp Name

This is the name of the group for which the information is being displayed.

Status

This is the status of the thread group. The thread group may be Active, Quiescing or Dormant. When a thread group is active, Com-plete can allocate and deallocate threads from that group at will. When the group is quiescing, any threads that have previously been allocated will remain available until they are deallocated by all users using them. When the last thread is deallocated, the thread group will have deemed to be quiesced and the control block will be marked as dormant.

Use Counts - Curr

This is the number of users with threads currently allocated from the thread group.

Use Counts - High

This reflects the highest number of users which had threads allocated in this thread group at any one time since the group was initialised.

Sgrps

This is the number of subgroups contained within the thread group.

Threads - Def'd

This is the number of threads which the installation wishes to have defined within the thread group.

Threads - Alloc

This is the number of threads actually allocated for the thread group. This may differ from the number of threads defined as when the number of threads is to be reduced, the threads must first be quiesced in order to let current users of the threads to be deleted, to finish their work. These threads will only be physically deallocated and disappear from this count when the last user deallocates the thread and the thread becomes dormant.

Note: Com-plete does not currently provide a mechanism to change the number of threads defined within a thread group dynamically, therefore the values given for 'Threads' should always remain constant throughout a given run of Com-plete.

        Command:
Subgrp

This is the name of the thread subgroup of which the thread in question is a member.

Status

This reflects the current status of the thread. The status is a combination of two state indicators separated by a dash ('-'). The primary state indicator is the letter preceding the dash and indicates whether the thread is Active, Quiescing or Dormant by the letters A, Q and D respectively. Active in this sense indicates that the thread is available to do work. When it is quiescing, it will remain active long enough to finish any work which has been started in the thread while dormant thread cannot be used and will have no secondary state associated with them. The secondary states which may occur are as follows:

'Free' Status

This indicates that the thread is free to run other work. If there was a previous user of the thread, this state indicates that this user's program ended or has been rolled out.

'Occ' Status

The 'occupied' status indicates that the thread is available to do work, however, the user program currently occupying the thread must first be rolled out prior to starting any other new work in the thread.

'Disp' Status

This indicates that the thread is reserved and the dispatcher is currently in the process of either starting a new user program or rolling in a user program which was previously rolled out.

'Run' Status

This indicates that the user program in the thread is currently running.

'Susp' Status

This indicates that the user program has been temporarily suspended as a wait was issued either directly by the user program or indirectly by a function used by the program. In this state, the user program may not be rolled out. Internally it indicates that the operating system task associated with the work is active elsewhere. Once the condition for the wait is satisfied, the task will continue processing this work.

Use Counts - Curr

This is the current use count for the thread. The use count includes the current user of the thread plus any other non relocatible users previously rolled out from this thread.

Use Counts - High

This reflects the highest ever use count experienced for the thread since the thread was initialised.

Wait Counts - Curr

This is the current wait count for the thread. This reflects the number of users waiting to run in the thread at the present time.

Wait Counts - High

This reflects the highest ever wait count experienced for the thread since the thread was initialised.

This is the key in which the user area of the storage is currently in when the thread is active, or is the key in which the last user of the thread left it. Note that the user area of the storage depends on the catalogue size of the current or last user of the thread.

Last Op

This is the last Com-plete operation which was issued in the thread.

Current/Last Active Userid

This is the userid of the current user active in the thread or the last user to be active in the thread if the thread has a status of 'free' or 'occ'. This may be blank in systems where logon is not forced and will generally be blank for ULOG sessions where the user is logging on.

Current/Last Active Program

This is the name of the program currently active in the thread, or the last program to be active in the thread if the thread has a status of 'free' or 'occ'. If the thread has never been used, this will be blank, however, once the thread has been used, this will always contain a value.

Current/Last Active Tid..

This is the tid of the current TIB active in the thread, or the last TIB to be active in the thread if the thread has a status of 'free' or 'occ'. If the thread has never been used, this will be blank, however, once the thread has been used, this will always contain a value.

Current/Last Active L

This is the level number on which the user currently active in the thread, or the last user to be active in the thread if the thread has a status of 'free' or 'occ', is running. If the thread has never been used, this will be blank, however, once the thread has been used, this will always contain a value. Level '0' will be displayed for a non-COM-PASS user, for a COM-PASS user who is running a program while something is stacked on all possible levels or for specific programs which must run on level 0 such as ULOG.

Time

When the thread has a secondary status of 'Susp' or 'Run', this will reflect the time in seconds that this user has spent in the thread.

TO Subfunction

The TO subfunction displays information about terminals and printer status. Information items include:

  • The name of the TIB onto which the user is logged;

  • TID number;

  • Device type;

  • User ID (if logged on);

  • Priority ;

  • Screen size;

  • Terminal status (ACTIVE, ERROR, etc.).

 Select function:      User ID:             PF7=up PF8=down PF10=left PF11=right 
         Command:

Use PF10 and PF11 to switch between the three screens.

The UserID input field is handled in the following way:

  • If data is entered with one or more non-numeric bytes, the data is treated as a user ID prefix. You can use the asterisk (*) as placeholder for any character

  • If a number within the range if TID numbers is entered, the number is taken as TID number. If the number entered falls outside the TID number range, it is taken as a user ID prefix.

  • To force any data to be taken as user ID prefix, precede the data with "U=".

US Subfunction

The US subfunction displays status information about user IDs currently logged on to Com-plete.

This function will display a list of users IDs and the current status of the programs they are running. As an operand, you can specify a user ID, or the first characters to be matched by userIDs. You can use asterisk "*" as a wildcard. If no operand is provided, a list of all users currently logged on will be displayed. The following display is a sample of what will be displayed.

 Select Function:      Operand:                                  PF7=up PF8=down
         Command:

Along with userID, terminal ID (TID), the name of the current program, the thread group and task group this program is running in, the current status of this program is indicated.

This status can be one of the following:

no program active

This is a non-Compass user which is not running any program at the moment.

running

This program is currently being executed by one of the subtasks.

subtask WAIT

This program is occupying a thread and a subtask, and is waiting for some event to occur.

Example: WAIT for an ENQ

program WAIT

This program is occupying a thread, but is waiting for some event to occur. The subtask which serviced the program before the WAIT is available to service other threads while this one is waiting.

Examples: I/O, WAIT for a Complete internal resource

ready to be rolled out

This program is in a state where it has issued a terminal write or ROLOUT, and can be rolled out of the thread when some other program needs one.

rolled out

This program is in a state where it has issued a terminal write or ROLOUT, and it has been rolled out to a roll buffer to allow some other program to run in the thread in the meantime.

queued: <queue name>

The program is on one of Complete's internal queues, indicated by the name of this queue. Refer to subfunction QO for an overview of the different queues. Most likely, the program is waiting for a certain subtask or for any subtask out of a task group to become available. If this state seems to last too long, use subfunction PL to find out who is occupying the subtask(s).

thread SG queue <subgroup name>

The program is waiting for any thread in the thread sub-group, indicated by the sub-group name, to become available. The program can run in any of the threads in this sub-group, but all of them are occupied. If this state seems to last too long, use subfunction TL to find out who is occupying all the threads in the sub-group.

thread queue in <subgroup name>

The program is waiting for a certain thread in the thread sub-group, indicated by the sub-group name, to become available. The program has been rolled out of this thread before, and needs to be rolled back into the same thread again, however, the thread is currently occupied by some other program. If this state seems to last too long, use subfunction TL to find out who is occupying the thread.

eoj in progress

This program has terminated, and Complete is cleaning up the thread behind it.

being dispatched

Sometimes, when switching from one of the above states to another, it can happen that the program has left the previous state, but is not in the next state yet.

Note:
For internal serialization reasons, it is not possible to terminate a program while it is on any of the queues. None of the operator commands IGNORE, CANCEL, LOGOFF, or FORCE will work in this situation. Instead, you should find out who is using the resource (thread or subtask) where a queue is building up, and ask him/her to free it (or CANCEL him/her if necessary).

VS Subfunction

The VS subfunction displays statistics about user VSAM files currently open, and about the local shared resource (LSR) pool if one is being used.

Irrespective of the number of ACBs in application programs referring to a given DD / DLBL name, Com-plete opens a single ACB for each DD / DLBL name and passes all requests through it. Statistics displayed about each ACB relate to the period of time since the ACB has been opened.

         Command:

If at least one of the ACBs currently open uses local shared resources, the last line on the screen containes statistics about the local shared resource pool.

Meaning of the information items according to column heading:

Heading Meaning
DDname The DD (z/OS) or DLBL (z/VSE) name.
STRN The value specified for the ACB parameter STRNO.
MAX The maximum number of requests concurrently active at any one time. (In z/VSE systems, available for the LSR pool only.)
noSTR The number of requests that failed due to a "maximum number of strings exceeded" condition.
Requests The number of requests issued by application programs.
Avg.Time The average response time, in seconds, for a request.
Users The number of user ACBs currently open in application programs.
(max) The maximum number of user ACBs open at any one time.
OPEN Time Date and time when the ACB was opened.
LostRPLs The number of request parameter lists (RPLs) pointing to this ACB and related to a request that could not be completed due to an abnormal termination.The most appropriate reason for a non-zero number in this field is application programs cancelled while waiting for completion of a VSAM I/O request. Uncompleted requests may result in other requests failing due to locked resources. This situation may be cleaned up by explicitly closing the "main" ACB using UUTIL subfunction FM (file maintenance) described in this section.
