Be familiar with the requirements and restrictions of Replication Server warm standby applications.
- One Replication Server manages
both the active and standby databases. Both the active and standby
databases must be from the same vendor.
- Replication Server does not switch client applications
to the standby database.
- Run the data server for the active and standby databases
on different machines. Putting the active and standby databases
on the same data server or hardware resources undermines the benefits
of the warm standby feature.
- Replication Server does not support warm standby replication between different platforms.
- Sybase recommends that tables in the active and
standby databases should have a primary key defined.
