Configuration Options for Backup and Recovery
There are several practical considerations related to directing online dumps to a
remote system:
•
Network bandwidth directly affects the speed at which remote dumps are
performed. If the link to the remote system has a low bandwidth, the dump takes
longer than it would on the local system. If your system has a Fiber Optic
Extension (FOX) link to the remote system, the dump is performed almost as
quickly as if it were being done on the local system.
•
The remote system must be accessible whenever online dumps are scheduled.
You should have an alternate site where you can direct online dumps if the primary
site experiences system downtime.
•
Coordination with operations staff at the remote site ensures that tapes are
mounted or that disks are available for online dumps as needed.
To direct audit dumping to a remote system, include the SYSTEM option in an ALTER
AUDITDUMP command.
To direct online dumping to a remote system if you are dumping to tape, include the
SYSTEM option in the DUMP FILES command.
To direct online dumping to a remote system if you are dumping to disk, include the
target system name in the disk file name you specify in the DISKMEDIA option in the
DUMP FILES command.
