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.
Cluster failover, redirection, and restorationTo maintain availability, you must plan for the failover of primary servers, redirecting client connections from unavailable servers, and restoring the cluster to its original configuration after a failure.
Failover configuration for high-availability clustersA failure in a high-availability cluster means that one of the servers is no longer available. If a primary server fails, you must promote a secondary server to the role of primary server. Connection Managers can be configured to perform automatic failover.

Failover configuration for high-availability clusters

A failure in a high-availability cluster means that one of the servers is no longer available. If a primary server fails, you must promote a secondary server to the role of primary server. Connection Managers can be configured to perform automatic failover.

You must set the DRAUTO configuration parameter to specify how failover is performed, and then use one of the following failover options:

Connection Manager
ISV cluster management software
Manual switchover
