Making the Switch

Making the switch from the active to the standby database consists of several tasks.

1. Disconnect client applications from the active database if they are still using it
2. In Replication Server, switch the active and standby databases
3. Restart client applications with the new active database
4. Start RepAgent for the new active database
5. Determine whether to drop the old active database or use it as the new standby database

• Disconnect Client Applications from the Active Database
  Before you switch to the standby database, you must stop clients from executing transactions in the active database.
• Switching the Active and Standby Databases
  Learn the procedure to switch the active and standby databases for a logical connection.
• Restart Client Applications
  When the admin logical_status command indicates that there is no operation in progress, or when the wait for switch command returns an isql prompt, you can restart client applications in the new active database.
• Manage the Old Active Database
  After you have switched to the new active database, you must decide what to do with the old active database.
