Monitoring Adabas Sessions

The Adabas session monitoring functions allow you to control and manage major Adabas resources. These functions are most useful when analyzing system performance or seeking the cause of performance problems. Session monitoring functions can be accessed from the Session Monitoring menu:

Note:
In cluster environments, the PF2 key allows you to scroll sequentially through nucleus IDs in the cluster using the NextNucid command. In addition, the current nucleus ID is shown in a NucID field on this screen. When the highest nucleus in a cluster is reached, PF2 causes AOS to cycle back to the beginning and changes the nucleus ID to the lowest nucleus ID in the cluster. Once the nucleus ID is changed, it remains in use for all Adabas Online System screens until it is changed again.

Using the session monitoring environment you can monitor the Adabas nuclei in a multiprocessing environment. When you enter the DBID of a cluster database on the Session Monitoring menu, subsequent screens include a field to specify the ID of the nucleus (NUCID) in the cluster you want to monitor:

  • If you do not set the nucleus ID, AOS defaults to the local nucleus.

  • If you set the nucleus ID to zero for a cluster database, the selected function is performed for all active nuclei in the cluster.

Using the AOS session monitoring environment, you can perform the following functions, accessible by menu option:

Option Function
A Displaying Cluster Members
C Maintaining User Profiles
D / P Displaying or Modifying Parameters
I Displaying Installed Products
L Displaying the Event Log Buffer
Q Displaying Queues
R Refreshing Interval Statistics
S Obtaining Current Snapshot Statistics
T Maintaining TCP/IP URLs
U Monitoring Interval Utilization
V Replicator Management
W Displaying Session Utilization
X Monitoring Cluster Usage
Z Displaying Maintenance Levels

Maintaining User Profiles

Adabas allows you to retain user-related information from session to session in a user profile table that includes

  • ET records;

  • user priority;

  • user-specific timeout (TNxx, TT, and TLSCMD);

  • ISN buffering (NSISN, NSISNHQ);

  • command ID (NQCID) values that differ from the established ADARUN values; and

  • owner ID information for multiclient files.

Selecting Maintain user profiles (option C) on the Session Monitoring menu displays the following Maintain User Profiles menu:

From the Maintain User Profiles menu, you can:

  • list and modify a user profile table (option L);

  • copy a user profile to one or more other users (option M); and

  • remove one or more ETIDs from the Adabas checkpoint file thereby deleting both profile and ET data (option X).

If necessary, you can supply a starting user ID. If the Start UID field is left empty, Basic Services displays entries starting from the beginning of the user profile table. You can use range notation for the starting value. For example, if you enter JA* in the Start UID field, the display begins with user IDs that start with the letters "JA".

If necessary, you can change the database by specifying the database ID in the Database ID field..

    You can modify existing profiles and add new user ones. For each user, you can maintain

    • a user priority to add "weight" to the normal, built-in priorities of Adabas commands issued by a specific user when they contend with other commands for Adabas database priority. The effect is to change the user's database access priority. An equivalent direct command is

      CHANGE PRIORITY
    • nonactivity timeout values for access-only users (TNAA), ET logic users (TNAE), and EXU users (TNAX).

    • transaction time limits for ET Logic users (TT).

    • a time limit for executing a database query (Sx) command (TLSCMD).

    • the number of ISNs allowed per TBI element (NSISN).

    • the number of records that can be placed in hold status at one time (NISNHQ).

    • the number of active command IDs allowed (NOCID).

    • an owner ID for multiclient support.

    Notes:

    1. If you press PF4 (ABC List) on any of these screens, an alphabetic list of the ADARUN parameter settings is shown.
    2. In cluster environments, the PF2 key allows you to scroll sequentially through nucleus IDs in the cluster using the NextNucid command. In addition, the current nucleus ID is shown in a NucID field on this screen. When the highest nucleus in a cluster is reached, PF2 causes AOS to cycle back to the beginning and changes the nucleus ID to the lowest nucleus ID in the cluster. Once the nucleus ID is changed, it remains in use for all Adabas Online System screens until it is changed again.

Start of instruction setTo modify Adabas nucleus (ADARUN) parameters:

  1. Choose option P on the Session Monitoring menu and press Enter. Modifiable values are highlighted (intensified) on the displays. The equivalent direct command is:

    MODIFY PARAMETERS

    A series of Modify Parameters screens appear. You can scroll through the screens using the PF7 (scroll backward) and PF8 (scroll forward) keys. The information on these screens and the number of screens that appear varies depending on the type database you have selected. For a description of each ADARUN parameter, read ADARUN Parameter Reference.

    The following screens might display for an Adabas database in an Adabas cluster:

    Notes:

    1. If you press PF4 (ABC List) on any of these screens, an alphabetic list of the ADARUN parameter settings is shown.
    2. In cluster environments, the PF2 key allows you to scroll sequentially through nucleus IDs in the cluster using the NextNucid command. In addition, the current nucleus ID is shown in a NucID field on this screen. When the highest nucleus in a cluster is reached, PF2 causes AOS to cycle back to the beginning and changes the nucleus ID to the lowest nucleus ID in the cluster. Once the nucleus ID is changed, it remains in use for all Adabas Online System screens until it is changed again.

    The following screen might display as the last screen of the series or parameter screens for an Adabas database that operates as an Event Replicator Server:

Displaying the Event Log Buffer

Selecting Display Event Log Buffer (option L) from the Session Monitoring menu invokes the Display Event Log Buffer screen.

The Adabas event log is a wraparound log in memory that is used to log each response code 145 (RSP145) event. The INFOBUFFERSIZE ADARUN parameter identifies the size of the Adabas event log. Each entry in the event log is currently 128 bytes, although this may change in later Adabas releases. When the Adabas event log fills up, the oldest entries in the log are overwritten.

This is the equivalent of running the ADADBS DEVENTLOG utility function.

Notes:

  1. The ET-ID (User-ID) field can be used to specify an ETID or security user ID (SECUID), as appropriate for your site.
  2. In cluster environments, the PF2 key allows you to scroll sequentially through nucleus IDs in the cluster using the NextNucid command. In addition, the current nucleus ID is shown in a NucID field on this screen. When the highest nucleus in a cluster is reached, PF2 causes AOS to cycle back to the beginning and changes the nucleus ID to the lowest nucleus ID in the cluster. Once the nucleus ID is changed, it remains in use for all Adabas Online System screens until it is changed again.

The Display Queues function shows, in table format, the contents of the user, command or hold queues. Each displayed table entry contains a related terminal ID (TID), job name, user ID (ET-ID or security user ID, as appropriate), current status, and related information such as files currently in use and command type.

If you try to display a queue that is currently empty, an appropriate message appears on the Display Queues menu.

Individual entries in the selected queues can be displayed to provide more detailed information, or selected for a later Basic Services function (the individual user-level statistics sampling described in section Obtaining Current Snapshot Statistics is an example).

This section covers the following topics:

Displaying User Queue Elements

If you select Display User Queue Elements (option A) on the Queue Displays menu, you must also specify the maximum number of elements to display. Other selection criteria you may optionally specify include:

  • number of seconds since last activity

  • logical user ID (ETID)

  • type of user (ACC, AOS, ET, EXU, EXF, UTI)

  • job name

  • terminal ID and

  • database ID

If multiple selection criteria are specified, they are combined with logical ORs.

The equivalent display direct command is:

In addition, the current nucleus ID is shown in a NucID field on this screen. When the highest nucleus in a cluster is reached, PF2 causes AOS to cycle back to the beginning and changes the nucleus ID to the lowest nucleus ID in the cluster. Once the nucleus ID is changed, it remains in use for all Adabas Online System screens until it is changed again.

The PF6 key allows you to switch columns of either having the ET-ID displayed or the security user ID (SECUID) displayed.

If you choose to display (D) an individual user ID, a user queue element information screen similar to the following appears:

Snapshot statistics provide information about file and command use either for a single user (user statistics) or for all currently active users (general statistics). The statistics must first be collected by starting a sampling period for which you have specified a time period in seconds (duration).

Start of instruction setTo obtain statistics for all currently active users

  1. Start general statistics (option G) and, after the specified duration, read them (option R).

    The equivalent direct commands are:

    START STATISTICS 
    READ STATISTICS

    For more information, read Basic Services Direct Commands.

    If user statistics are started (option U) or subsequently read (option S after the specified duration), a user ID must either be indicated on this screen or have been previously selected in the Display User Queue (PF2) or Display Command Queue options. PF4 is used to deselect a previously selected user ID.

This section covers the following topics:

Three screens of statistics are displayed: the first two show command usage (use PF7 and PF8 to toggle between these; the third shows file usage (use PF4 to toggle between the file usage and command usage screens):

Command Usage Display

The following general command usage information for all currently active users is displayed:

Note:
In cluster environments, the PF2 key allows you to scroll sequentially through nucleus IDs in the cluster using the NextNucid command. In addition, the current nucleus ID is shown in a NucID field on this screen. When the highest nucleus in a cluster is reached, PF2 causes AOS to cycle back to the beginning and changes the nucleus ID to the lowest nucleus ID in the cluster. Once the nucleus ID is changed, it remains in use for all Adabas Online System screens until it is changed again.

This section covers the following topics:

Monitoring Command Usage

Selecting Command Usage (option C) on the Interval Utilization menu displays the Command Usage screen, which shows the total and average execution time of each Adabas command type issued during the current session and processed by the Adabas nucleus. It also shows the total of all Adabas commands issued.

The values shown on this screen are shown in compressed form. Each can display as a nine-digit value, with appropriate multiplier letters "k" (1000), "M" (1000000), "G" (1000000000), and "T" (1000000000000) (representing consecutive powers of 1000) if necessary. On any of these screens, you can press PF9 to see the actual values (without the multipliers) of the counters on the screens. In this view (full view), there are fewer statistics on each screen, so there are more screens to page through. To return to compressed view, just press PF9 again.

If the value of a counter on these screens ever exceeds the space available for the statistic, the statistic will display in red.

The equivalent direct command is:

Adabas includes some V* and Y* commands , which you may see mentioned in Adabas shutdown statistics or in Adabas Online System (AOS) screens. These commands are used internally by Adabas and Adabas add-on products and should not be used in direct calls in your applications. Should you use them, errors will result.

Monitoring File Usage

Selecting File Usage (option F) on the Interval Utilization menu displays the File Usage screen , which shows one of the following things.

  • If you select file number 0 (zero) on the Interval Utilization menu, all files of the database used during the session and the number of accesses to each file are displayed on the File Usage screen.

    The equivalent direct command is:

    DISPLAY FILUSAGE

Reviewing High Water Marks

Selecting High Water Marks (option H) on the Interval Utilization menu displays the use of major Adabas pools and queues. It shows the size of each pool or queue as well as the highest amount or the pool or queue used and the current amount in use.

Note:
The Replication Pool may appear as "Replication N/A" on this screen if the database is not an Event Replicator Server or if replication is not activated for the database.

The HW Used column and the %Used column following it show the highest size (in bytes) and highest percentage of the pool or queue reached in the current session. These counters may be doubleword fields. They are shown as nine digits with an optional multipler letter: "k" (1000), "M" (1000000), "G" (1000000000), and "T" (1000000000000), representing consecutive powers of 1000.

These values are a good starting point when looking for a problem with limited buffer, pool, or queue space, or if you are looking for unused storage resources.

The equivalent direct command is:

DISPLAY HWM

A multiple-screen report appears.

You can select each line to see the full values of the pool or queue, since only nine digits can be displayed. Simply enter an "s" to the left of the pool or queue and a popup window appears showing you the full values for that pool or queue. The following sample shows detailed high-water statistics for the hold queue.

Note:
You can select more than one pool or queue at a time; multiple popup windows will appear in sequence (you only need to press any key to move to the next one). When all the popups have been displayed once, you are returned to the High Water Marks selection screen.

The time and date values on this popup window show you when the highest value was reached. Values may be zero when the pool/queue is not used. For the attached buffer pool, no time and date value are given. Also, note that Work part 3 values show the leftover amounts after the Work allocation of Work parts 1 and 2.

Monitoring Work Pool (LWP) Usage

Selecting Work Pool (LWP) Usage (option L) on the Interval Utilization menu displays the length of the used and unused parts of the work pool as well as the length of the longest single unused part. These numbers can be used to tune the work pool length for the next session.

The equivalent direct command is:

In an Adabas cluster environment, the file may be locked for exclusive use by another cluster nucleus. If this is the case and the file is in the nucleus file status table, the Locking NucID column for the file shows the ID of the nucleus that has exclusive control.

The Access count and Update count columns display the number of access or update users, respectively, that refer to the specified file in their user queue elements (UQEs). These users either have specified the file in an OP command with the "R" option or are using the file in an as yet incomplete transaction.

The State column indicates when the file is used for access only or for access and update. It indicates to what extent a nucleus can use a file on its own. If the requested use exceeds the given state, the nucleus must first communicate with the other nuclei in the cluster in order to upgrade the state.

Reviewing Protection Log (PLOG) Status

Selecting Protection Log (PLOG) Status (option P) on the Interval Utilization menu displays the status of dual protection logs, if used.

Reviewing System Status

Selecting System Status (option S) on the Interval Utilization menu displays I/O counts for the ASSO, DATA, WORK, and PLOG data sets; remote and local call distribution; and other current session status information.

The equivalent direct command is:

DISPLAY SYSTEMSTATUS

The values shown on this screen are shown in compressed form. Each can display as a nine-digit value, with appropriate multiplier letters "k" (1000), "M" (1000000), "G" (1000000000), and "T" (1000000000000) (representing consecutive powers of 1000) if necessary. On any of these screens, you can press PF9 to see the actual values (without the multipliers) of the counters on the screens. In this view (full view), there are fewer statistics on each screen, so there are more screens to page through. To return to compressed view, just press PF9 again.

If the value of a counter on these screens ever exceeds the space available for the statistic, the statistic will display in red.

Note:
The values on the sample screens in this section have been artificially enhanced.

Monitoring Thread Usage

Selecting Thread Usage (option T) on the Interval Utilization menu displays a table of all defined Adabas threads, the status of each, the command type currently in process in each active thread, and the number of commands processed by each thread in the current session.

The equivalent direct command is:

DISPLAY THREADUSAGE

The values shown on this screen are shown in compressed form. Each can display as a nine-digit value, with appropriate multiplier letters "k" (1000), "M" (1000000), "G" (1000000000), and "T" (1000000000000) (representing consecutive powers of 1000) if necessary.

If the value of a counter on these screens ever exceeds the space available for the statistic, a greater than symbol (>) appears as the multiplier letter.

Reviewing I/Os by Volume Serial Number

Selecting I/O by Volser (option V) on the Interval Utilization menu displays a table of the read and write I/Os performed by volume serial number on the I/O by Volser screen. It also shows the highest RABN on each volume.

The equivalent direct command is:

DISPLAY IOVOLSER

The I/O counts shown on this screen are shown in compressed form. Each can display as a nine-digit value, with appropriate multiplier letters "k" (1000), "M" (1000000), "G" (1000000000), and "T" (1000000000000), representing consecutive powers of 1000, if necessary.

On all subscreens of cache statistics, displayed counters may include a unit code, with the following possible values:

Unit Code The total shown is in . . .
blank bytes
k 1000 bytes
M 1,000,000 bytes
G 1,000,000,000 bytes
T 1,000,000,000,000 bytes

If a value has a unit code shown, it has been divided by the unit measurement to convert it to bytes, showing the significant digits to nine places with no decimal point.

Press PF9 to see the entire value. This value is the exact count up to 20 digits in length.

Each of the options on the Lock Statistics menu displays statistics for a particular lock. For each lock, the screen displays obtain-and-release information about the various types of that lock that are currently in use by a cluster nucleus:

  • The system may obtain locks conditionally or unconditionally, synchronously or asynchronously. A conditional request for a lock may be granted or rejected.

  • Releases may be issued synchronously or asynchronously.

  • The system may alter locks conditionally or unconditionally, synchronously or asynchronously, A conditional request to alter a lock may be granted or rejected. An unconditional request to alter a lock may be deadlocked and rejected.

For example, choosing Hold ISN Lock (option N) on the Lock Statistics menu displays the Hold ISN Lock screen:

Maintenance levels for each module are displayed. Any zaps that are applied to the module are also listed.

The list of modules can be limited by entering a specific module name in the Select Module Name field at the top of the screen. An asterisk (*) can also be used as a wildcard value in this field. For example, specifying "ADARUN" displays information for the ADARUN module only. Specifying "ADAR*" lists all modules with names that begin with "ADAR", which would include ADARUN as well as ADARVU and other modules.
