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 ReferenceThe HCL OneDB™ Administrator's Reference includes comprehensive descriptions of HCL OneDB™ configuration parameters, the system-monitoring interface (SMI) tables in the sysmaster database, the syntax of database server utilities such as onmode and onstat, logical-log records, disk structures, event alarms, and unnumbered error messages.
Configuring and monitoring HCL OneDB™
Database configuration parametersThe HCL OneDB™ database server uses a configuration file, which is called the onconfig file, during initialization. This file contains default configuration parameter values. You can modify the parameter values to improve performance and other characteristics of the instance or database.
PC_POOLSIZE configuration parameterUse the PC_POOLSIZE configuration parameter to specify the maximum number of user-defined routines that are stored in the UDR cache.

PC_POOLSIZE configuration parameter

Use the PC_POOLSIZE configuration parameter to specify the maximum number of user-defined routines that are stored in the UDR cache.

onconfig.std value: PC_POOLSIZE 127
values: A positive value 127 or greater that represents the maximum number of entries in the cache. A positive value 127 or greater that represents half of the initial maximum number of entries in the cache. The maximum value is dependent upon the shared memory configuration and available shared memory for the server instance.
takes effect: After you edit your onconfig file and restart the database server.; When you increase the value in memory by running the onmode -wm command.; When you reset the value in memory by running the onmode -wm command.

The initial number of entries in the cache is twice the value of the PC_POOLSIZE configuration parameter. For example, if the PC_POOLSIZE configuration parameter is set to 127, 254 entries are allowed in the cache. If all entries in the cache are full, the cache size automatically grows by 10%. To reduce the size of the cache, decrease the value of the PC_POOLSIZE configuration parameter in the onconfig file and restart the server.
