Replication Agent 15.5 introduces database resynchronization for Oracle to rematerialize your replicate database and resume replication without the risk of data loss or data inaccuracy, and without forcing a quiesce of your primary database. Database resynchronization is based on obtaining a data dump from a trusted source and applying the dump to the target database you want to resynchronize. See the Replication Agent 15.5 Primary Database Guide and the Replication Server 15.5 Heterogeneous Replication Guide.
This feature only works with Replication Server 15.5.
Replication Agent introduces new commands and enhances some existing commands to support database resynchronization:
pdb_skip_missing_user – configures Replication Agent behavior for missing session information. The default behavior is to skip processing of any command for which no session or user information is available.
lr_dump_marker – applicable for Oracle only, this parameter configures the Replication Agent to send a dump database marker to Replication Server when the first log recorded with System Change Number (SCN) is larger than or equal to the configured value. This works only when Replication Agent is running in resync mode.
resume – supports a new resynch parameter, which allows your to start Replication Agent in resync mode.
ra_status – enhanced to verify whether Replication Agent is running in resync mode. When Replication Agent is resumed in resync mode, ra_status returns “Replicating - Resynchronization” as the status.
See the Replication Agent 15.5 Reference Manual.
