Integrating SAP R/3 and Data Protector

Configuring an SAP R/3 Backup

 

the backup specification.

 

— In the SAP parameter file, set:

 

backup_dev_type = rman_util

 

rman_channels = <number_of_channels>

 

rman_parms =

 

"ENV=(OB2BARTYPE=SAP,OB2APPNAME=<DB_Name>,

 

OB2BARLIST=<Backup_Specification_Name>)"

 

Before starting an incremental backup, ensure that the appropriate full

 

backup is done using the following option:

 

-m full (using BRBACKUP) or backup_mode=full (in the SAP

 

parameter file)

Incremental

To start an incremental backup, specify the Incr mode in the Data

Backups if Using

Protector GUI or the Incr mode in the CLI, as follows:

RMAN

omnib -sap_list <SAP_Backup_Specification> -barmode incr

 

Manual Balancing of Files into Subsets

Manual balancing allows you to precisely tailor the performance of an SAP R/3 backup by grouping files into subsets that are backed up in parallel. Make sure that:

• You use only one file from the same hard disk at a time.

• The number of files in a subset is equal to or smaller than a concurrency number, that is, the sum of concurrencies of all devices configured in the backup specification.

• If you do not specify all the files, other files that need to be backed up are added to the list automatically using the load balance option. Before backup, this list of files is logged in the <ORACLE_HOME>/sapbackup/.*.lst (UNIX systems) or <SAPDATA_HOME>\sapbackup\*.lst (Windows systems) file.

• You specify the file subsets in the manual_balance section of the Data Protector integration configuration on the Cell Manager in the /etc/opt/omni/server/integ/config/SAP/<client_name>%<ORAC LE_SID> (UNIX systems) or
