AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
System administrationThese topics contain concepts, procedures, and reference information for database and database server administrators to use for managing and tuning HCL OneDB™ database servers.
Administrator's GuideThe HCL OneDB™ Administrator's Guide provides the information required to administer HCL OneDB™.
High availability and scalabilityA successful production environment requires database systems that are always available, with minimal if any planned outages, and that can be scaled quickly and easily as business requirements change.

Backup and restore with high-availability clusters

You cannot perform most backup and restore operations on secondary servers.

Before you can establish a server as an HDR (high-availability data replication) or RS (remote stand-alone) secondary server, you must perform a cold restore on it.

After you have set up a server as an HDR or RSS secondary server, you can only perform the following backup and restore operations:

You can perform a logical restore on HDR or RS secondary servers when you are setting up a high-availability cluster.
You can perform an external backup on an RS secondary server. For more information, see the HCL OneDB™ Backup and Restore Guide.

SD secondary servers must be shut down during a cold restore of the primary server, but can be online during a warm restore, after they have been shut down and restarted.
