This document describes operational procedures and processes for Adabas Review after it has been installed and initialized.
Note:
This section applies only when using Adabas Review in local mode.
If Adabas Review processing terminates abnormally (abends) in RAOSLOCL, the Adabas Review ESTAE routine is given control.
This routine traps the abend, and prints diagnostic information and a dump to expedite the analysis and resolution of the abend to ADASNAP.
The routine also disables Adabas Review processing for the remainder of the Adabas nucleus session.
If you need help resolving the abend, contact your Software AG technical support representative with the printed information.
Adabas is protected from termination if Adabas Review abends. Adabas processing continues without interruption.
Note:
Although Adabas is temporarily unavailable during dump processing,
it continues processing as usual once the dump has completed.
Users attempting to access Adabas Review following a trapped abend receive the following message:
Review not installed on database
The progress of the error handling routine is reported by messages written to the console. For OS/390 and z/OS, the following are example sequences of console messages sent during abend processing:
REVESTAE - REVIEW ESTAE EXIT DRIVEN REVESTAE - REVIEW NOW DISABLED REVESTAE - ABEND 000C1000 PSW 078D2000 80129E98 REVESTAE - R0 00000002 - R1 0D652DD0 - R2 000FD240 - R3 000FBCC0 REVESTAE - R4 00129C48 - R5 0D50AFA8 - R6 0D6E8000 - R7 001331F8 REVESTAE - R8 0D50B0E8 - R9 800E93E0 - R10 00042000 - R11 0D5007E0 REVESTAE - R12 80128C48 - R13 00128D68 - R14 001294BA - R15 8000DD10 REVESTAE - DUMP HAS BEEN TAKEN REV20126 - REVIEW SUB-TASK DETACHED REV20129 - HISTORY SUB-TASK DETACHED
Note:
This section applies only when using Adabas Review in local mode.
Statements must be added to the Adabas startup job to accommodate Adabas Review. These statements are added during the installation of Adabas Review.
The added statements control many of the operating features of Adabas Review. Some identify parameter files that may be edited by the Review administrator.
The startup statements may be edited, or additional statements may be needed, depending upon the needs of your site. However, deleting any of these statements affects the functioning of Adabas Review and is, therefore, not recommended.
The following is a listing of the statements added to the Adabas startup job during Adabas Review installation.
For OS/390 and z/OS, the following statements are added to the Adabas startup JCL:
//RVUEXI DD DISP=SHR,DSN=REVvrs.SRCE(RVUEXI) //RVUEXP DD SYSOUT=X,LRECL=80,RECFM=FBA //RVUALT DD DISP=SHR,DSN=REVvrs.ALTHIST //RVUAUT1 DD DISP=SHR,DSN=REVvrs.SRCE(AUT1PARM) //RVUAUT2 DD DISP=SHR,DSN=REVvrs.SRCE(AUT2PARM) //RVUCARD DD DISP=SHR,DSN=REVvrs.SRCE(RVUCARD) //RVUFLD DD DISP=SHR,DSN=REVvrs.SRCE(USRPARM) //RVUPARM DD DUMMY //RVUPRT00 DD SYSOUT=X,LRECL=133,RECFM=FBA //RVUPRT01 DD SYSOUT=X,LRECL=133,RECFM=FBA //RVUPRT02 DD SYSOUT=X,LRECL=133,RECFM=FBA //RVUPRT03 DD SYSOUT=X,LRECL=133,RECFM=FBA //ADASNAP DD SYSOUT=X
, where vrs is the current version, revision, and system maintenance level of Adabas Review.
The Adabas startup statements listed above identify files that are used by Adabas Review. Each of these files is described in the following section, Files Used by Adabas Review.
This section describes the files used by Adabas Review:
RVLOG01 and RVLOG02 are the default names for the sequential command logging files. Each report performing command logging must reference a unique file name prefix and the number of command log files associated with that file name prefix.
Note:
All command log data sets for a particular report must be the same
size.
Adabas Review allows each report to have up to 99 command log files, and writes to these files in sequential order.
A DD statement must be added to the JCL for each command log file. The names of these command log files are made up of the file name prefix and a sequential number.
The data sets for these command log files may be allocated using IEFBR14 with the following DCB attributes:
RECFM=VB,BLKSIZE=10000,LRECL=9996,DSORG=PS
Note:
While RECFM and DSORG cannot be altered, the combination of LRECL
and BLKSIZE can be altered (for example, LRECL=27998, BLKSIZE=27994) to make
better use of disk storage.
Refer to the section Command Logging Considerations for more information.
Adabas Review reports may specify whether the data accumulated by the report will also be written to the Adabas Review repository. Historical data is useful for monitoring database performance and for performing trend analysis.
The parameters that determine whether Adabas Review writes historical data are set when a user creates or edits a report definition. These history parameters appear on the Report Options screen of the Edit Report (ER) function.
If historical data is to be written by a report running in batch mode, the history parameters make up the COPY statement.
A RVUALT job control statement can identify an alternate sequential file to which historical data may be written when it cannot be written to the Adabas Review repository.
In hub mode, the Adabas Review hub startup JCL contains a RVUALT statement.
In local mode, the Adabas startup JCL must be modified to include a RVUALT statement during the Adabas Review installation procedure.
RVUALT data sets must be allocated:
In hub mode, a separate RVUALT data set must be allocated for each Adabas Review hub.
In local mode, if Adabas Review is installed on multiple databases, an RVUALT data set must be allocated for each database.
The RVUALT history file is allocated using the following DCB attributes:
RECFM=VB,BLKSIZE=10000,LRECL=9996,DSORG=PS
 |
Warning: Use IEBGENER to allocate the RVUALT file, since an EOF (end-of-file) must be written for the file. Allocation with IEFBR14 will not write the EOF mark. In hub mode, the sample JCL member MAKEALT will do this. |
Adabas Review receives a response code 148 (Adabas not active) and writes the data to the file specified by the RVUALT job control statement (if it has been assigned in the job stream) in situations where the Adabas Review repository is:
unavailable (in hub mode).
on the same database that is being monitored (in local mode). The response code is returned when the database is brought down and Adabas Review tries to write the historical data.
The next time the Adabas Review hub is started, another subtask is started to copy the historical data from the RVUALT file to the Adabas Review repository.
RVUAUT1 and RVUAUT2 are data sets that contain the report definition control statements for autostarted reports. Adabas Review generates the statements and writes them to these files. When Adabas is initialized, the reports are started automatically.
The installation procedure for OS/390 and z/OS defines DD statements RVUAUT1 and RVUAUT2 so that they point to members of a PDS. To avoid constant compression of these data sets, the DD statements may be modified to point to sequential data sets.
RVUCARD is a data set used by the GENCARD command. The GENCARD command creates batch parameter statements from report definitions created online.
The command requires the user to supply a DDNAME, and the generated statements are written to the corresponding file.
RVUEXI is a parameter file that contains parameters to control the Adabas Review operating environment. The Adabas Review administrator may edit the RVUEXI parameters according to the specific needs of the site.
Refer to the section Editing the RVUEXI Parameter File for more information.
RVUEXP is a companion file to RVUEXI and if specified, any parameter processing errors encountered in RVUEXI will be written to the RVUEXP output file.
The RVUFLD data set contains parameter control statements for creating user-defined fields. Parameters in this data set define the length, type, and location of reporting fields to be determined by the user.
The recommended procedure is to set RVUPARM to "dummy". In previous releases, batch parameter statements were read from this file. Because these statements may now be generated using the GENCARD command, you no longer need to code batch parameters manually. Parameters may be coded in this data set if desired, and Adabas Review will access this data set prior to accessing data sets specified by RVUAUT1 and RVUAUT2.
When RVUPARM has been "dummied", the following message is displayed:
REV20164 - Open failed for RVUPARM
In this case, the message is normal and should be ignored. The message does not occur if instead you create a RVUPARM data set that contains only an asterisk.
The following logical printer files are used by Adabas Review:
RVUPRT00 is the Adabas Review logical printer for statistics about Adabas Review operations, such as number of reports, number of records processed, etc.
RVUPRT01 and above are Adabas Review logical printers used for reports. One logical printer is shared by all summary reports; each detail report requires its own logical printer. A job control statement corresponding to each logical printer must be added to the Adabas Review hub (in local mode, to the Adabas) startup job control (JCL).
Assignment of reports to logical printers is as follows:
Review statistics are written to RVUPRT00.
Summary reports are written to RVUPRT01.
The first detail report is written to RVUPRT02
Additional detail reports begin at RVUPRT03 and increment the printer number for each additional report. When a detail report is purged, the corresponding printer number is freed. The next detail report started will reuse the lowest available printer number.
The RVUEXI file contains parameters to control the Adabas Review operating environment. The Adabas Review administrator may edit the RVUEXI parameters according to the specific needs of the site.
This section covers the following topics:
| Parameter | Possible Values | Default |
|---|---|---|
| UIDT-CELLS | 100-10000 | 1000 |
The user ID table is managed using a hashing algorithm. This value is numeric and specifies the number of eight-byte cells that should be allocated to the user ID table manager.
| Parameter | Possible Values | Default |
|---|---|---|
| UCMD-TIMEOUT | 0-999 | 60 |
A small reentrant storage area is allocated for each active user of the Adabas Review online system (LIST, VIEW, START, PURGE reports functions). This area is deallocated when the user finishes each online request.
However, if the user's Natural session terminates abnormally during an Adabas Review operation, the Adabas Review nucleus may not have the opportunity to deallocate the reentrant area.
Specifying the UCMD-TIMEOUT parameter gives the Adabas Review nucleus a timeout value after which these inactive areas are deallocated. The timeout value is numeric and is specified in minutes.
| Parameter | Possible Values | Default |
|---|---|---|
| UIDT-TIMEOUT | 1-999 | 60 |
To report on the field TPTRANCT, Adabas Review must maintain a work area for each user that accesses Adabas. This area is called the user ID table.
If this field is specified in a report, the facility is activated and an area is allocated when Review receives the first call from each user. The area is deallocated when Review receives an Adabas CLOSE (CL) command for that user.
However, if the user's application does not issue a CL during termination, Review is unaware that the session has terminated.
The UIDT-TIMEOUT parameter is used to expire inactive user ID table elements. If the field TPTRANCT is not specified in any active reports, Review will not maintain user ID table elements for each user. This value is numeric and specifies the timeout value in minutes.
This section discusses administrative considerations when performing Adabas Review command logging.
Note:
This section applies only when using Adabas Review in local mode.
Command log information is passed from Adabas to Adabas Review. Under some conditions, information is returned to Adabas. Information flows between Adabas Review and Adabas as follows:
Adabas passes command logs to Adabas Review. All Adabas command logging information is passed to Adabas Review.
The user determines what information is reported.
Adabas Review users are given the option to suppress any unnecessary information on a report-by-report basis. This option is available from the Edit Report (ER) function. The user selects from parameters that mirror the ADARUN parameters.
The user has options for determining how command logging is processed for reports. However, the Adabas Review administrator must complete the following tasks to set up the Adabas Review environment so that command logging can take place:
Allocate command log data sets. Command log data sets must be allocated for reports.
Add job control statements to the Adabas Review hub (in local mode, Adabas) startup JCL.
Each report that performs command logging must have a command log file assigned to it. For each command log file, there must be a corresponding job control statement in the Adabas Review hub (in local mode, Adabas) startup JCL.
The name must be a five-character name followed by a sequential number (01, 02, etc.) corresponding to the number of command logs. For example, if the name is CMLOG and there are two data sets to be defined, two statements are required with names as follows:
CMLOG01 and CMLOG02
The five-character name is referenced by the report in the command logging report option FILE. The total number of data sets is referenced by the report in the command logging report option NUM OF LOGS.
Refer to the section RVLOG01 and RVLOG02 Command Logging Files for more information.
Adabas Review writes to command log files in sequential order. When a command log file is filled, Adabas Review closes the file and switches to the next sequential file. If all files have been filled, Adabas Review switches back to the oldest file and begins again.
If a command logging user exit is not specified, Adabas Review simply closes a filled command log file and opens the next file. When all files are filled, Adabas Review writes over the file containing the oldest data.
A user exit is provided so that the data contained in the command log file may be copied to a new file before the command log file is overwritten with new command log data. This user exit is called each time a command log file is closed or opened.
The source library member LOGUEXIT contains sample code for the user exit that processes command logs. You may modify this exit so that it conforms to your site requirements, and users may include the exit name on the Report Options screen of their report definition.
When a command log file is closed, the user exit starts the command log copy job. The jobs member REVCLCOP contains a sample command log copy job.
This job copies the contents of a filled command log file to another device and appends the new data to existing data. This job also reinitializes the end-of-file marker in the command log file.
When a command log file is opened, the user exit checks the position of the end-of-file marker to determine if there is any data in the command log file.
If the position indicates that there is no data in the file, Adabas Review writes command log data to the file.
If the position indicates that there is data in the file, Adabas Review sends a message to the operator asking whether Review should wait until the copying of the command log is completed, or begin writing to the command log file and overwrite the existing data.
The Adabas Review administrator can modify configuration parameter values in the Natural text member CONFIGDB.
To access and modify these parameters:
At the Natural NEXT prompt, type LOGON SYSREVDB and press ENTER.
After modifying the parameters, type SAVE and press ENTER to save the changes.
Type MENU at the prompt to return to Adabas Review.
CONFIGDB, which contains the Adabas Review configuration parameters, is saved in the Natural library SYSREVDB.
| Parameter | Possible Values | Default |
|---|---|---|
| CURSOR-POSITION | BOT | TOP | BOT |
Specifies whether the cursor is placed on the command line (BOT) in list displays, or on the SEL field (TOP).
| Parameter | Possible Values | Default |
|---|---|---|
| DECIMAL-CHAR | NAT|char | NAT |
Specifies the decimal character to use when generating Review reports. The value specified overrides the value specified for the NATPARM DC parameter. If the value specified is NAT then the value specified in the NATPARM DC parameter is used. To determine the current setting of the NATPARM DC parameter, issue GLOBALS at the NEXT prompt.
| Parameter | Possible Values | Default |
|---|---|---|
| PC-FILE | 'text' | 'DOWNLOAD-PC-FILE-5' |
Specifies the value to be used in the DOWNLOAD statement in the Review-generated programs. The value specified must be delimited with single apostrophes. The field is alphanumeric, maximum 20 characters.
| Parameter | Possible Values | Default |
|---|---|---|
| RVBX-MESSAGE | YES | NO | YES |
Specifies whether to display error messages about the incorrect installation of the Adabas Review link routine exits during installation verification.
| Parameter | Possible Values | Default |
|---|---|---|
| UBAR | any valid character | | |
Specifies the character to be used in maps as the vertical border. Any character recognized by your system is valid; the default value is "|".
| Parameter | Possible Values | Default |
|---|---|---|
| CLOSE-DBID | YES | NO | NO |
Specifies whether to issue a close (CL) command to the old Adabas Review database when a new database is accessed with the HUB= (DBID=) command.
| Parameter | Possible Values | Default |
|---|---|---|
| REVIEWDB-UEX | name | exit not enabled |
Specifies the name of the site-dependent Natural routine to be called for validation of a user's access to an Adabas Review function.
Refer to Natural source member N-USEXIT for more information on the calling and processing conventions for this exit.
| Parameter | Possible Values | Default |
|---|---|---|
| MAXIMUM-MAXK | 0 | nnnn | 0 |
Specifies the maximum value that can be specified for the report option, Max K. The Max K value determines the maximum amount of storage available for a specific report.
A value of 0 (the default) indicates that the Max K option is not restricted.
When specifying a value, MAXIMUM-MAXK must be 4 or greater for OS/390 or z/OS.
| Parameter | Possible Values | Default |
|---|---|---|
| OPEN-DBID | YES | NO | NO |
Specifies whether an open (OP) command is issued to the new Adabas Review database when a new database is accessed with the HUB= (DBID=) command.
User exit 5 is called by the Adabas nucleus when an event occurs with the Adabas Review hub. An event is defined as:
a connection made with the Adabas Review hub during Adabas session open;
a connection broken with the Adabas Review hub during Adabas session close; or
a non-zero return code received from the send operation for a command log record.
The exit is invoked with AMODE=31 and should return control in the same state.
The exit is required to process logging errors. It determines how the failure is handled. The record that was not logged and the response code received from the Adabas Review hub logging request are provided to assist in making the determination.
On entry, the register 1 points to the following parameter list:
| Parm | Usage |
|---|---|
| 0(R1) | Exit call indication. The value of this byte can
be:
|
| 1(R1) | Action to handle a logging error (ignored for
open and close). The exit must provide one of the following values for this
field in the parameter list for a logging error:
|
| 2(R1) | Response code for logging errors. This response code is the same as the Adabas response code in the Adabas Messages and Codes documentation. |
| 4(R1) | Fullword where the exit must provide a wait time (in seconds) for the logging failures that are to be retried after waiting. |
| 8(R1) | Address of the command log record that the Adabas nucleus was attempting to send to the Adabas Review hub. |
| Value | Description |
|---|---|
| R13 | Save area of calling Adabas nucleus routine. |
| R14 | Return address in Adabas nucleus. |
| R15 | Entry point address for exit. |
For logging errors, the exit is required to set a value in the operation field. If the wait value (W) is chosen, the exit is also required to provide a non-zero time value.
Register 15 should be set to zero. All other registers should be returned intact.
Review has two Natural user exits. These exits are located in the Review system library in Natural, and may be modified by using the Natural editor. They are applicable to both the Adabas Review and Review DC systems.
| Use: | You may place coding in this program to allow for site-specific needs. |
| Invoked: | This program is invoked when the online portion of Review is entered. |
| Example 1: | Setting colors on (SET CONTROL 'T3279') |
| Example 2: | Turning the PC mode on or off. |
| Remark: | This program must not alter the Natural stack, and it must end with a STOP command. |
| Use: | You may place coding in this program to alter the processing that occurs when terminating Review. |
| Invoked: | This program is invoked when the online portion of Review is terminated. |
| Example 1: | Returning to Natural rather than terminating your session. |
| Example 2: | Logging onto another Natural application. |
| Remark: | Returning to a previous Natural application (using SETUP/RETURN). |
