Recovery

Troubleshooting

started. You are recommended to use the archive directory of the ”recovery instance“ for this purpose. You can determine which directory this is by issuing the following command:

show parameter log_archive_dest

In this case you can use the autorecovery option; after you call recover database ... ORACLE will then automatically process the redolog files. If you use one or more other directories you will have to specify the pathname for each redolog file interactively with

ORACLE.

Backups are much simpler if the archive directory has the same path on all the instances. In this case NetWorker will copy the redolog files to the correct location straightaway.

If the database was backed up offline, then proceed as described in the section “Manual Recovery”.

A recovery until time (using ora_recut) can be carried out both for offline and online backups and can only be run on the OPS node, which also starts the database backup.

If you note when recovering the tablespaces that you also have to recreate directories that are in the pathnames of the tablespaces, please check the owner and group of these directories. NetWorker normally creates new directories with the owner root, which will cause access problems in the case of a database directory.

Please note that when the recovery has finished, the archiving monitor (amon) will have to be restarted on each individual (!) node of the OPS system.

No space left on device xxx

You may possibly receive this error message during a recovery. Apart from the fact that there might really be insufficient space on the disk, there is also the possibility that an sqldba-, svrmgrl-, sqlplus- or some other database process is blocking the required disk space. In this case you only need to terminate the database processes.
