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.
LOG_INDEX_BUILDS configuration parameterUse the LOG_INDEX_BUILDS configuration parameter to enable or disable index page logging.

LOG_INDEX_BUILDS configuration parameter

Use the LOG_INDEX_BUILDS configuration parameter to enable or disable index page logging.

onconfig.std value: Not set.
values: 0 = Disable
1 = Enable
takes effect: After you edit your onconfig file and restart the database server.; When you reset the value dynamically in your onconfig file by running the onmode -wf command.; When you reset the value in memory by running the onmode -wm command.

Usage

If LOG_INDEX_BUILDS is enabled, logical log file space consumption will increase, depending on the size of the indexes. This might lead to logical log file backups being required more frequently. Messages are written to the online.log file when index page logging status changes.

Tip for RS secondary servers: Using onmode -wm enables or disables index page logging for the current session only, and does not affect the setting in the onconfig file. If the server is stopped and restarted, the setting in the onconfig file determines whether index page logging is enabled. Therefore, enabling index page logging using onmodem -wm is not recommended when using RS secondary servers; instead, use onmode -wf to update the onconfig file, so that index page logging is enabled after restarting the server. Index page logging is a requirement when using RS secondary servers.
