Recovery

Selecting a tape backup the database recovery process is the same as the one for a usual database recover performed by NSR-ORA (see also section “Recovery Until Time with Logical Errors”).

If you specify a recovery using a snapshot NSR-ORA first tries to perform a switchlog of the most recently created log files and then stops the database and archivelog daemon. Subsequently NSR-ORA allows the administrator to perform the recovery using the snap restore command. For every required filer volume the following dialog appears:

Do you want to do a snap restore for the volume

/vol/mangan1 on filer netapp

The DB Files are on top of the volume but if there are other files aside, they will also be resetted

(ny) (default y) >

i

If the top level database directory is not equal to the mounting point the warning created by NSR-ORA will be more urgent and in this case the default answer is “n”.

With a snap restore selected NSR-ORA checks the relevant volume to see if the archivelog files are stored on it. If so the following warning message is displayed:

ATTENTION !!! ATTENTION !!! ATTENTION !!!

================================================================

The Archivelog directory ’/netapp_oracle/saparch’ is on the same volume as the DB files you want to restore!

If you go on all current archivelog files will be overwritten. Should I move the files or should I overwrite them?

1)copy the files

2)overwrite the files

3)abort the recover session > 2

Are you really sure that you want to overwrite the existent logfiles???

Be aware that the DB could be irrecoverable if you overwrite needed logfiles!

Overwrite? (y n) > y
