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.
High-availability cluster configuration
Configuring clustersConfigure clusters by securing confirming the hardware, operating-system, and database requirements. You also set up a security protocol and the secure connection.
Database server configuration requirements for clusters
Logical-log configuration

Logical-log configuration

All log records are replicated to the secondary server. You must configure the same number of logical-log files and the same logical-log size for both database servers. The following ONCONFIG parameters must have the same value on each database server:

LOGBUFF
LOGFILES
LOGSIZE
DYNAMIC_LOGS

The database server logs the addition of logical-log files. Logical-log files added dynamically on the primary server are automatically replicated on the secondary server. Although the DYNAMIC_LOGS value on the secondary server has no effect, keep DYNAMIC_LOGS in sync with the value on the primary server, in case their roles switch.
