This section of the documentation describes operational procedures and processes for Adabas Review after it has been installed and initialized.

This document covers the following topics:

• Assigning Logical Units

• Processing ABENDs

• Adding Adabas Start-up Statements at Installation

• Files Used by Adabas Review

• Editing the RVUEXI Parameter File

• Command Logging Considerations

• Modifying Configuration Parameters

• User Exit 5 (Adabas Review Hub Event Handler)

• Review Natural User Exits

Assigning Logical Units

Adabas Review uses the following logical units (SYS numbers):

Any of these logical units may be changed if they conflict with logical units already in use.

To change logical unit numbers used by Review

1. Edit the supplied source member RAOSLUBS.A in the Review library.

   This member is self-documenting.

2. Make the necessary changes.

3. Assemble and link RAOSLUBS.A using your site-specific JCS.

Processing ABENDs

Note:
This section applies only to Adabas Review in local mode.

If Adabas Review processing terminates abnormally (ABENDs) in RAOSLOCL, the Adabas Review STXIT 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.

ABEND Protection for Adabas

Adabas is protected from termination if Adabas Review ABENDs. Adabas processing will continue without interruption.

Note:
Although Adabas will be temporarily unavailable during dump processing, it will continue processing as usual once the dump has completed.

Message to Adabas Review Users

Users attempting to access Adabas Review following a trapped ABEND will receive the following message:

Review not installed on database

Messages to the Console

The progress of the error handling routine is reported by messages written to the console. The example sequences of console messages provided in this section are sent during ABEND processing:

Adding Adabas Start-up Statements at Installation

Note:
This section applies only to Adabas Review in local mode.

Statements must be added to the Adabas start-up 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 start-up statements may be edited, or additional statements may be needed, depending upon the needs of your site. However, deleting any of these statements will affect the functioning of Adabas Review and is, therefore, not recommended.

Adabas Start-up Statements

For VSE/ESA, the following statements are added to the Adabas start-up job stream during Adabas Review installation:

Note:
The logical units shown in the example below may be reassigned if there are conflicts with your site-specific logical units. Refer to the section Assigning Logical Units for more information.

where vvvvvv is the volume serial number of the target disk, nnnn is the relative track number, and vrs is the version, revision, and system maintenance level of Adabas Review.

The Adabas start-up 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.

Files Used by Adabas Review

RVLOG01 and RVLOG02 Command Logging Files

RVLOG01 and RVLOG02 are 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 datasets for a particular report must be the same size.

Under VSE/ESA, Adabas Review allows each report to have up to 99 command log files, and writes to these files in sequential order.

DLBL, EXTENT, and ASSGN statements must be added to the JCS 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 datasets for these command log files are created when they are opened.

Refer to the section Command Logging Considerations for more information.

RVUALT History File

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 JCS contains a RVUALT statement.

• In local mode, the Adabas startup JCS must be modified to include a RVUALT statement during the Adabas Review installation procedure.

RVUALT datasets must be allocated:

• In hub mode, a separate RVUALT dataset must be allocated for each Adabas Review hub.

• In local mode, if Adabas Review is installed on multiple databases, an RVUALT dataset must be allocated for each database.

The RVUALT history file is allocated using the job DBFILES.

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 (in local mode, the next time Adabas is started), another subtask is started to copy the historical data from the RVUALT file to the Adabas Review repository.

RVUAUT1 and RVUAUT2 Report Definition Datasets

RVUAUT1 and RVUAUT2 are datasets 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.

Under VSE/ESA, this file is created by the installation job DBFILES.X.

RVUCARD Dataset for the GENCARD Command

RVUCARD is a dataset used by the GENCARD command. The GENCARD command creates batch parameter statements from report definitions created online.

The command requires the user to supply DLBL, EXTENT, and ASSGN statements, and the generated statements are written to the corresponding file.

RVUEXI Parameter 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 Companion Output File

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.

RVUFLD User Field Parameter Dataset

The RVUFLD dataset contains parameter control statements for creating user-defined fields. Parameters in this dataset define the length, type, and location of reporting fields to be determined by the user.

RVUPARM Dummy Dataset

The recommended procedure is to set RVUPARM as a dummy dataset by assigning SYS005 to IGN. 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 dataset if desired, and Adabas Review will access this dataset prior to accessing datasets specified by RVUAUT1 and RVUAUT2.

Note:
When RVUPARM has been "dummied", the message REV20164 - Open failed for RVUPARM is displayed. In this case, the message is normal and should be ignored. The message does not occur if instead you create a RVUPARM dataset that contains only an asterisk.

RVUPRTnn Logical Printer Files

RVUPRT00 for Adabas Review Statistics

RVUPRT00 is the Adabas Review logical printer for statistics about Adabas Review operations, such as number of reports, number of records processed, etc.

RVUPRTnn Files for Reports

RVUPRT01, 02,...nn

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) start-up job control (JCS).

Assignment of logical printers to reports depends on the order in which the reports are started:

• If the first report started is a summary report, RVUPRT01 is used for all summary reports.

• If the first report is a detailed report, RVUPRT01 is assigned to the detailed report, and another logical printer is used for summary reports. When a detail report is purged, the corresponding printer number is freed. The next detail report started will reuse the lowest available printer number.

Editing the RVUEXI Parameter File

The RVUEXI file contains parameters to control the Adabas Review operating environment. The Adabas Review administrator may edit the following RVUEXI parameters according to the specific needs of the site:

Note:
Default values are underlined in the following tables.

RVUEXI User-Specified Parameter

The user ID table is managed using a hashing algorithm. This value is numeric and specifies the number of 8-byte cells that should be allocated to the user ID table manager.

RVUEXI Timeout Parameters

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.

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.

Command Logging Considerations

This section discusses administrative considerations for Adabas Review command logging.

Command Logging Information Flow

Note:
This section applies only to Adabas Review in local mode.

Command log information is passed from Adabas to Adabas Review. Under some conditions, information is returned to Adabas. This section explains the flow of information between Adabas Review and Adabas, and the parameters required to accomplish this.

1. Adabas passes command logs to Adabas Review.

   All Adabas command logging information is passed to Adabas Review.

2. 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.

Setting Up Command Logging

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:

1. Allocate command log datasets.

   Command log datasets must be allocated for reports.

2. Add job control statements to the Adabas Review hub (in local mode, Adabas) start-up JCS.

   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) start-up JCS.

   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 datasets to be defined, two statements are required with names as follows:

   CMLOG01
   CMLOG02

   The five-character name is referenced by the report in the command logging report option FILE. The total number of datasets 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.

Using the Command Logging User Exit

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.

LOGUEXIT

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.

End-of-File Marker Position

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.

Modifying Configuration Parameters

The Adabas Review administrator can modify configuration parameter values in the Natural text member CONFIGDB.

To access and modify these parameters

1. At the Natural NEXT prompt, type LOGON SYSREVDB and press ENTER.

2. Type the command EDIT CONFIGDB and press ENTER. Modify the parameters as required.

3. Type SAVE and press ENTER to save the changes.

4. Type MENU at the prompt to return to Adabas Review.

CONFIGDB File Parameter Description

CONFIGDB, which contains Adabas Review parameters, is saved in the Natural library SYSREVDB.

Specifies whether the cursor is placed on the command line (BOT) in list displays, or on the SEL field (TOP).

Specifies the decimal character to use when generating Review reports. The value specified should match the value specified for the NATPARM DC parameter. To determine the current setting of the NATPARM DC parameter, issue GLOBALS at the NEXT prompt. The Review default value for DECIMAL-CHAR is a period ('.').

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.

Specifies whether to display error messages about the incorrect installation of the Adabas Review link routine exits during installation verification.

Specifies the character to be used in maps as the vertical border. Any character recognized by your system is valid; the default value is "|".

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.

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.

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 VSE/ESA.

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 (Adabas Review Hub Event Handler)

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 nonzero 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.

Input Parameters

On entry, the register 1 points to the following parameter list:

Other Register Values at Entry

Output Parameters

• 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 Natural User Exits

Review has two Natural user exits. These exits are found 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 Data Communication systems.
