• RXA_SHUTDOWN - The Replication Agent shuts down.

Commit transaction

The Replication Agent is committing a transaction on the target server.

VOID rxOnCommitTransaction(prxEVENT prxagentev);

Input Parameters: rxEVENT with rxTRNOP (see Callback Function Input Parameters)

Output Parameters: rxEVENT action field:

• RXA_DEFAULT - The Replication Agent commits the transaction on the target server.
• RXA_SKIP - The Replication Agent does not commit the transaction on the target server.
• RXA_SHUTDOWN - The Replication Agent shuts down.

Abort transaction

The Replication Agent is aborting a transaction on the target server.

VOID rxOnAbortTransaction(prxEVENT prxagentev);

Input Parameters: rxEVENT with rxTRNOP (see Callback Function Input Parameters)
