Db2 for Linux®, UNIX, and Windows (LUW) – online and archive logs

When using CDC Replication with a DB2® for LUW database, you will require the following accesses:

• Physical access to the Db2 online logs and archive logs on disk.
• Db2 log retention to be active so that logs are archived instead of overwritten.
• Retention of the Db2 online logs and archive logs for as long as CDC Replication is shut down or latent.

To minimize the impact on your database, the CDC Replication log reader only performs read-only operations when working with your database logs and will never write directly to these files. This reduces disk contention on your log files and minimizes the impact on your database.
