Minimizing time-out failures on large database restores
Large database restores sometimes fail when multiple restore sessions compete for resources. In this situation, a restore session can be delayed while NetBackup waits for media or device access. If the delay is too long, the restore session times out. Use the following procedure to minimize session time-outs and to allow the restore jobs to complete successfully.
To minimize time out failures on large database restores
- Open the NetBackup web UI.
- On the left, select Hosts > Host properties.
- Select the check box for the client.
- If necessary, select Connect.
- Select Edit client.
- Select Timeouts.
- Set the Client read timeout property to a large value.
The default for the Client read timeout setting is 300 seconds (5 minutes). For database agent clients, increase the value significantly from the recommended value.
See the NetBackup Web UI Administrator's Guide.
For example, change this setting to 30-60 minutes to minimize time-out errors.
- Select Save.
Note:
This change may delay detecting problems during subsequent backups. Consider putting the original value back in place once any restore that requires a change is complete.
