Disaster Recovery Procedures for NetBase Shadowing Environments
12-7
Case Three
The Case Three scenario assumes that the master system fails and the shadow system is set up to
operate in a “standalone” environment. No shadowing will be done during this failover.
Planned Failover
The following guidelines can be used for a planned failover.
On the master system:
1. Quiet the system (except for the NetBase background job).
2. Flush all transactions to the shadow system.
RUN NBFLUSH.PUB.NETBASE,STOPWAIT;PARM=ShadowNode#
3. Stop the NetBase background job:
RUN NBCTRL.PUB.NETBASE;INFO=“STOP NETBASE”
On the shadow system:
4. Quiet the system (except for the NetBase background job).
5. Check the directory for any out of sync conditions:
RUN NBSYNC.PUB.NETBASE,VERIFY;INFO=“@.@.@”
If any files are out of sync, they should be resynced before continuing.
6. Change the directory to reflect that this is a “standalone” system:
RUN NBCTRL.PUB.NETBASE;INFO=“CHGDIR newdir”
