You might want to pause HotStandby (HSB) operations temporarily on the primary server, for example, if you are taking the secondary server out of service for upgrade and the primary server does not have enough disk space to store the transaction logs that accumulate while the secondary server is out of service. See Running out of space for transaction logs for more details.
To pause HSB on the primary server, complete the following steps:
1 Disconnect the servers (if they are currently connected) by running the following command:
ADMIN COMMAND 'hotstandby disconnect';
2 Set the primary server to STANDALONE state by running the following command:
ADMIN COMMAND 'hotstandby set standalone';
The primary server continues to operate as a non-HotStandby server.
Note After you have stopped storing transaction logs to send to the secondary server, you can no longer have the primary and secondary servers catch up merely by connecting the servers again. Instead, you must synchronize the servers manually when you resume HSB operations. For more information, see Synchronizing primary and secondary servers
