NSR-ORA and NetApp

Recovery

i

The saveinfo.sh command is not relevant to the NDMP backup method, and it will not be started after the backup has completed. If the backup process has been performed successfully you will be informed by the savegrp completion notification.

6.5.3Debugging

To enable debugging functions NSR-ORA creates a number of files within the /nsr/oracle/{ORACLE_SID}/prot/dbg directory for every backup performed. In this directory you can find records of the communication between NSR-ORA and the NetApp filer, between NSR-ORA and Networker and, finally, between NSR- ORA and Oracle. If any problems occur during the communication it is recom- mended to send a copy of the relevant record file to your IT service.

6.6Recovery with NSR-ORA

In general there are no syntax changes to the commands of the recovery process from NSR-ORA V3.1B to the newer version 3.2. This section describes the processes and procedures involved in performing a recovery of NetApp backups.

6.6.1Recover until time (ora_recut)

Performing a Recover until time NSR-ORA checks, whether there is a snapshot preceding the specified time. Later you will be asked to decide to use this snapshot or an respective tape backup for the recovery.

Example:

ora_recut -t 2001-07-27:16:55:00 NET816 Which saved Version do you want to use

1)the Snapshot from <Jul 27 16:46 nsrora_NET816_actual>

2)the tape version from <Jul 27 16:38

nsrora_NET816_NDMP_ONLINE> (default 1:) >
