What the STRMNTBRM Command Does

The STRMNTBRM command provides assistance for a variety of housekeeping and maintenance tasks, and also produces useful reports that are based on your media information. IBM recommends that you run this command each day after the last save has completed. You can place this command on an automatic scheduler or in the last *EXIT entry in the last control group used to process your backup. Instructions to do this are provided later in this chapter. In either case, it is important that the STRMNTBRM command be run after the save of the BRMS media information. Failure to do so will result in an inaccurate recovery report.

The STRMNTBRM command works by processing existing commands, such as the STREXPBRM and WRKMEDBRM commands. It also performs unique tasks that are specified on the STRMNTBRM command.

The STRMNTBRM command can perform the following tasks and prints the following reports when processed:

Expires media.
Removes history records for expired media.
Produces a report that lists expired media.
Determines which, if any, libraries did not save.
Produces a report on recovery activities (contact information).
Collects volume error statistics and updates volume error logs.
Cleans up any temporary files that are left over from prior operations.
Cleans or changes journal receivers as needed and attaches new ones. Deletes old journal receivers that are based on the information in Q1APRM data area. The default is to keep the information for five days.
Performs media movement (if specified).
Optionally reorganize the BRMS databases so that the deleted records in the files are removed to minimize the BRMS storage requirements on the local system.

The key reports run by the STRMNTBRM command are:

Backup Activity Report

This report identifies libraries and objects that were not saved. Use it to look for errors in your save operation and take action as appropriate.

Save Strategy Exceptions Report

Use this report to see which libraries, if any, were not saved, and to help you devise save strategies for them. If the report indicates that BRMS did not save a library already in a control group, you need to investigate why the error occurred.

Notes:

You can also run the WRKMEDIBRM SAVTYPE(*NONE) command to see a list of unsaved libraries.
If you want the libraries on an independent auxiliary storage pool (I-ASP) to show on this report, you will need to run a SETASPGRP for the I-ASP prior to running this report option. You will have to repeat this process for every I-ASP.

Note:

You can also run the WRKMEDIBRM SAVTYPE(*NONE) command to see a list of unsaved libraries.

BRMS Recovery Reports

The STRMNTBRM command can produce any number of the three essential recovery reports (Recovery Analysis, Volume Summary, and ASP Recovery). If desired, you can make this request from the Print recovery reports parameter.

Centralized Media Audit Report

The STRMNTBRM command produces this report for each system in a network. BRMS does not generate this report if you have a single-system environment. See Networking with BRMS, for more information about this report.

Tape Volume Report, Volume Threshold Report, and Volume Statistics Report

The STRMNTBRM command generates these reports automatically. These reports show volumes that have equalled or exceeded the usage or read/write threshold limits that are set for the media class. Check these error thresholds and take appropriate action to replace volumes with errors.

Following is a summary of the commands that can be automatically processed by the STRMNTBRM command. You can also process these commands individually if desired.

MOVMEDBRM = Runs media movement.
RMVLOGEBRM = Removes BRMS log entries.
RMVMEDIBRM = Removes media information from BRMS.
STREXPBRM = Starts expiration for BRMS.
STRRCYBRM = Runs the Recovery Analysis/Recovering Your Entire System, Volume Summary and ASP analysis reports.
WRKMEDBRM = Runs the Expired media report.
WRKMEDIBRM = Generates a media information summary report.
WRKRCYBRM = Runs Recovery activities report.

Because the STRMNTBRM command processes so many commands and reports, IBM strongly recommends that you review and select each of the parameters on the STRMNTBRM command very carefully. You can review complete descriptions of all of the parameters on the STRMNTBRM command by using the online help that is available for each parameter on the command.

To review the STRMNTBRM display, type STRMNTBRM at a command line and press F4 to prompt the display.
