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.

Renaming chunks

Renaming chunks

About this task

If you use symbolic links for chunk path names, you can rename chunks while HDR is operating. For instructions on renaming chunks, see the HCL OneDB™ Backup and Restore Guide.

If you do not use symbolic links for chunk path names, you must take both database servers offline while renaming the chunks, for the time that it takes to complete a cold restore of the database server.

To rename chunks on a failed HDR server:

Procedure

Change the mode of the undamaged server to standard.
Take a level-0 backup of the standard server.
Shut down the standard server.
Rename the chunks on the standard server during a cold restore from the new level-0 archive (for instructions, see the HCL OneDB Backup and Restore Guide).
Start the standard server.
Take another level-0 archive of the standard server. Be sure the server is in standard mode.
Restore the failed server with the new level-0 backup and reestablish the HDR pair.
