AI extents on the source database

AI extents can fill up on the source database. If you set the parameter -aistall during startup, processing will pause if your AI extents become full. If you do not set the startup parameter -aistall, and your AI extents fill up, processing will end. If either condition occurs, AI extents need to be emptied.

To empty AI extents, enter the following command:

RFUTIL source_db_name -C aimage extent empty 

AI extents cannot be emptied until they are replicated to the target. When source database activity continues during failure recovery or with the use of the defer-agent-startup property, the AI file can grow rapidly. You need to provide for enough space in your AI file to accommodate for this, or processing stalls if the AI file becomes full. If processing stalls and Fathom Replication cannot continue, Fathom Replication can be disabled online.

To disable Fathom Replication online, enter the following command:

DSRUTIL source_db_name -C DisableSiteReplication source
