Backup Recovery and Media Services

BRMS for IBM i

BRMS creates files in the /tmp/brms directory that are used by service personal when diagnosing problems with BRMS.

In the current design, when these files reach a size of 10 MB, they will be renamed to *.bku and a new file will be created. When the new file reaches 10 MB, the previous *.bku file will be deleted and the new file will be renamed to *.bku.

Note : With the following PTFs or their superseding PTF applied, the default size will be 50 MB :

SI42923 (V5R4M0)
SI42924 (V6R1M0)
SI42925 (IBM i 7.1)

The size of the flight recorders can be increased if required. To increase the size, see the following URL : http://www.ibm.com/systems/i/support/brms/dataAreas.html#A_Q1AMAXFR

The user cannot prevent these files from being created.

If a user deletes these files, it is with the understanding that:

  1. They will be created when required by BRMS
  2. If a problem occurs in BRMS, it may be difficult for service personal to diagnose the problem without these files.

The following is a list of the files that may be in the /tmp/brms directory:
 

 /tmp/brms/flightrec current BRMS flight recorders of the most current BRMS activity on the system
 /tmp/brms/flightrec.bku backup of the last /tmp/brms/flightrec file
 /tmp/brms/assert A snapshot of the BRMS flight recorders taken by BRMS when certain errors are encountered
 /tmp/brms/assert.bku backup of the last /tmp/brms/assert file
 /tmp/brms/diary current BRMS flight recorder that records only key events so that we can get a view of what happened on the system over an extended period of time.
 /tmp/brms/diary.bku backup of last /tmp/brms/diary file
 /tmp/brms/install current BRMS flight recorders for installations of BRMS, upgrades or PTF installs
 /tmp/brms/install.bku backup of the last /tmp/brms/install file
 /tmp/brms/performance current BRMS flight recorder data used to help determine how long different options of BRMS took - saves, outfile processing, maintenance
 /tmp/brms/performance.bku backup of the last /tmp/brms/performance file
 /tmp/brms/qbrms current BRMS flight recorder of all BRMS activity done with the user profile QBRMS - media synchronization , networking etc.
 /tmp/brms/qbrms.bku backup of the last /tmp/brms/qbrms file
 /tmp/brms/tapetms current BRMS flight recorder containing only media management information
 /tmp/brms/tapetms.bku backup of last /tmp/brms/tapetms file
 /tmp/brms/TSMAPIS Contains information on calls to the BRMS exit programs used by the Tivoli Storage Manager (TSM) for IBM i and TSM for Portable Application Solutions Environment (PASE) servers.
 /tmp/brms/TSMAPIS.bku backup of the last /tmp/brms/tmsexits file.

Domino flight recorders

If you turn on the environment variables for Domino flight recorders, they will also show up in /tmp/brms.

 /tmp/brms/qnninsdb.yyyymmdd.trc

The Domino flight recorders for saves of online Domino data, where yyyy is the year, mm is the month and dd is the day when the save occurred.

DEBUG_QNNINSDB must be set to '1'.
 /tmp/brms/qnninbrme.yyyymmdd.trc

The Domino flight recorders for restores of online Domino data, where yyyy is the year, mm is the month and dd is the day when the restore occurred.

DEBUG_QNNINBRU must be set to '1'.
 /tmp/brms/qnninbir.yyyymmdd.trc

The Domino flight recorders for restores of incremental online Domino data, where yyyy is the year, mm is the month and dd is the day when the restore occurred.

DEBUG_QNNINBRU must be set to '1'.
