Abstract
Techniques are provided for copying data from a source database to a target database in a database replication system which includes a database event mining system, an event interceptor process and an event receptor process. In one aspect, the event interceptor detects a failure in the event receptor and switches to a mode in which it rejects new database events from the database event mining system. The event interceptor can also request that the database event mining system resend the event after a specified delay. The event interceptor can also shut itself down for a specified period of time, then restart and listen for a pairing request from the event receptor. In another aspect, the event receptor can request that the database event mining system send event data from a specified system change number.
