Chapter 7 Recovering From Errors : Partial Recovery

Partial Recovery
If your analysis indicates that the damage is isolated to a specific Pagestore segment, the following steps indicates how to recover just that segment. If you are unsure if other segments are affected, the safest approach is to restore all segments.
Do not restore a segment to a point prior to the last physical definition change for any table held in that segment. Access errors can result when users attempt to use the table, due to a mismatch between the physical data and the recovered table definition. Make sure your MetaStor (segment 0) backup corresponds with the segment being restored.
Implementing a Partial Recovery
1.
a.
b.
hrncr dboffline=segmentname or segmentnumber
For example:
hrncr dboffline=sales
hrncr dboffline=3
You can also vary a segment offline using the Administration menu. Refer to TIBCO Object Service Broker for Open Systems Installing and Operating for more information about the menu’s options and operator commands.
2.
Use a recent backup of the affected segment or your most recent full system backup. For example, to rebuild segment 1 only, type the following:
hrntlrps -s 1 backup.000
3.
The command to vary a segment online is:
hrncr dbonline=segmentname or segmentnumber
You can also bring the segment online from the Administration menu.
