Integrating SAP DB/MaxDB and Data Protector
Integration Concept
Chapter 3 257
SAP DB/MaxDB dbmcli. The sapdbbar.exe module issues dbmcli
commands that configure SAP DB/MaxDB backup media (parallelism),
configure sapdb_backint and then start the backup using
SAP DB/MaxDB dbmcli. SAP DB/MaxDB then starts the configured
sapdb_backint component. For every SAP DB/MaxDB medium (pipe)
sapdb_backint starts a DMA, which transfers the data from
SAP DB/MaxDB media (pipes) to Data Protector media. This procedure
is the same for full, differential, and transactional backup. Additionally,
if the configuration (including media specification and the backup
history) is selected for backup, it is backed up directly by the
sapdbbar.exe module and DMA. The list of configuration files to be
backed up is retrieved through dbmcli.
See Figure 3-1 on page 258.
NOTE When running a backup using SAP DB/MaxDB utilities,
SAP DB/MaxDB media and pipes must be configured manually.
Restore Flow When a restore session is started, the Cell Manager starts the
sapdbbar.exe module, which starts SAP DB/MaxDB dbmcli. The
sapdbbar.exe module issues commands to SAP DB/MaxDB dbmcli to
configure sapdb_backint and SAP DB/MaxDB backup media
(parallelism). SAP DB/MaxDB then starts the configured
sapdb_backint, which starts streaming data to media (pipes) that
SAP DB/MaxDB created. For every SAP DB/MaxDB medium (pipe) the
sapdb_backint starts a DMA, which transfers the data from Data
Protector media to SAP DB/MaxDB media (pipes). If SAP DB/MaxDB
configuration is being restored, it is the sapdbbar.exe module and DMA
that perform the restore.
See Figure 3-1 on page 258.
NOTE When running a restore using SAP DB/MaxDB utilities, SAP DB/MaxDB
media and pipes must be configured manually.
