Configuring SAP for Oracle Subclients for Archive Log Backups

You use archive logs backups to recover database transactions that have been lost due to an operating system or disk failure or to recover lost database transactions.

You apply the archive logs to an online backup to recover the database.

Best Practice: Create separate subclients to back up log files because they are mandatory for recovering data.

Note

If the archive log destination is different than the default $SAPDATA_HOME/saparch location, set the <SID>_sSAPARCH Additional Setting to enable the CommCell Console backup to obtain the new SAPARCH location.
Archive log backups that you initiate from the CommCell Console use BRARCHIVE with the -OSC syntax and only permit one backup cycle. For more information, see the SAP note 214370, SAP NOTE 214370.

Before You Begin
