AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
Enterprise ReplicationThe HCL OneDB™ Enterprise Replication Guide describes the concepts of data replication using HCL® OneDB® Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.
Planning and designing for Enterprise ReplicationBefore you set up your replication system, plan how to include Enterprise Replication into your database server environment, design your database schema by following Enterprise Replication requirements, and then design your replication system between database servers.
Plan for Enterprise Replication Before you design a replication system, you must understand how Enterprise Replication interacts with the database server and the other requirements of Enterprise Replication. Many aspects of the HCL OneDB™ database server can affect how you deploy Enterprise Replication.
Back up and restore of replication serversYou can back up and restore database servers that participate in Enterprise Replication.

Back up and restore of replication servers

You can back up and restore database servers that participate in Enterprise Replication.

Do not stop Enterprise Replication before performing a backup on database servers that participate in replication.

Warm restores are not permitted. You must perform a cold restore up to the current log of all relevant dbspaces on Enterprise Replication servers before resuming replication.

If the restore did not include all the log files from the replay position, or the system was not restored to the current log file, you must advance the log file unique ID past the latest log file unique ID prior to the restore, and then run the cdr cleanstart command followed by the cdr sync replicate command to synchronize the server.
