03/25/09 Using the Save While Active command within IBM's BRMS backup management software

The following example is for an SAP application environment that is using an iSeries high availability software product, which is typically used for disaster recovery purposes. Because of this, the tape backup is performed on the replication target (backup) system.

The data library for the SAP environment is being saved with the Save While Active command:

Display Backup Control Group Entries S102XXXX

Group . . . . . . . . . . : R3PRDDATA
Default activity . . . . : *BKUPCY
Text . . . . . . . . . . : Save of R3PRDDATA - High Availability End and Start

Auxiliary Weekly Retain Save SWA
Backup List Storage Activity Object While Message
Seq Items Type Pool Device SMTWTFS Detail Active Queue
10 *EXIT *DFTACT
20 *EXIT *DFTACT
30 R3PRDDATA *SYSBAS *DFTACT *ERR *YES *LIB

The first user exit point in the BRMS Control Group ends the replication data group target processes:

User Exit Maintenance S102XXXX


Type command, press Enter.

Sequence number . . . . . . . : 10
Where used . . . . . . . . . : *EXIT
Weekly activity . . . . . . . : *DFTACT SMTWTFS
Command . . . . . . . . . . . . ENDDG DGDFN(R3PRD) PRC(*ALLTGT) ENDOPT(*CNTRLD) WAIT(500) TIMOUTOPT(*ENDIMMED)


The second user exit point uses the BRMS MONSWABRM process that watches for the Save While Active checkpoint message. Once the checkpoint message is received, the replication data group target side processes are restarted:

User Exit Maintenance S102XXXX


Type command, press Enter.

Sequence number . . . . . . . : 20
Where used . . . . . . . . . : *EXIT
Weekly activity . . . . . . . : *DFTACT SMTWTFS
Command . . . . . . . . . . . . MONSWABRM LIB(R3PRDDATA) CMD(STRDG DGDFN(R3PRD)) WAITMSG(7200)
