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.
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
Storage space and chunk configuration

Storage space and chunk configuration

The number of dbspaces, the number of chunks, their sizes, their path names, and their offsets must be identical on the primary and secondary database servers. In addition, the configuration must contain at least one temporary dbspace if the HDR secondary server is used for creating activity reports. See Use of temporary dbspaces for sorting and temporary tables.

UNIX™ Only:: You must use symbolic links for the chunk path names, as explained in Allocating raw disk space on UNIX.
Important: If you do not use symbolic links for chunk path names, you cannot easily change the path name of a chunk. For more information, see Renaming chunks.

The following ONCONFIG parameters must have the same value on each database server:

ROOTNAME
ROOTOFFSET
ROOTPATH
ROOTSIZE
