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.
LOW_MEMORY_MGR configuration parameterUse the LOW_MEMORY_MGR configuration parameter to enable automatic low memory management, which you can use to change the default behavior of a primary or standard server when it reaches its memory limit.

LOW_MEMORY_MGR configuration parameter

Use the LOW_MEMORY_MGR configuration parameter to enable automatic low memory management, which you can use to change the default behavior of a primary or standard server when it reaches its memory limit.

onconfig.std value: LOW_MEMORY_MGR 0
values: 1 = Enables automatic low memory management when the database server starts.
0 = Disables automatic low memory management.
takes effect: After you edit your onconfig file and restart the database server.

Usage

If you configure a primary or standard server to use a percentage of the SHMTOTAL configuration parameter value for automatic low memory management start and stop thresholds, the SHMTOTAL configuration parameter must be set to a positive integer value.

Attention: Changing the value of the SHMTOTAL configuration parameter can cause the configuration of automatic low memory management to become invalid, forcing the database server to use default settings.

To enable automatic low memory management, specify:

LOW_MEMORY_MGR 1
