Additional configuration required for NetBackup for SAP with Network Attached Storage (NAS) on UNIX or Linux
Additional configuration is required if you want to use Network Attached Storage (NAS).
Table: Additional configuration for NAS
Backup type | Configuration |
|---|---|
RMAN proxy backups with NAS | Keep all database data files on the NAS. Other database files should be located on the local file system. (These files include the online redo logs, control files, archive redo logs, Oracle executables, and the configuration files.) |
BACKINT backups with NAS | Keep all database data files, online redo logs and all copies of control files on the NAS. Other database files including Oracle executables, configuration files (e.g. SAPBACKUP directory, initCER.utl) and the archive redo logs should be under the local file system. |
Online backups | Use the BR_CNTRL_DIR environment variable to define the control file location for brbackup. The control file should be located on the NAS. (By default brbackup makes a copy of the control file in the SAPBACKUP directory, which is on the local file system. brbackup then provides that copy for backup). |
Offline backups | No special configuration is required. |
The following is an example of how to use the BR_CNTRL_DIR variable.
bash# export BR_CNTRL_DIR=/oracle/CER/cntrl_loc
Where /oracle/CER/cntrl_loc should be on the NAS. It should not be located where the actual control file resides.
