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.
DB_LIBRARY_PATH configuration parameterUse the DB_LIBRARY_PATH configuration parameter to specify a comma-separated list of valid directory prefix locations from which the database server can load external modules, such as DataBlade® modules. You can also include server environment variables, such as $ONEDB_HOME, in the list.

DB_LIBRARY_PATH configuration parameter

Use the DB_LIBRARY_PATH configuration parameter to specify a comma-separated list of valid directory prefix locations from which the database server can load external modules, such as DataBlade® modules. You can also include server environment variables, such as $ONEDB_HOME, in the list.

You must specify the paths to the external modules exactly as the paths are registered with the database server. Relative paths or paths that include double periods (..) are not valid. External modules in the file systems that are not specified by this parameter cannot be loaded. This list is scanned prior to loading C language modules.

If you set this configuration parameter, you must also include the string $ONEDB_HOME/extend as part of the value. If the string $ONEDB_HOME/extend is not included in DB_LIBRARY_PATH, built-in extensions, DataBlade modules, and the BladeManager utility do not load.

onconfig.std value: Not set
if not present: The database server can load external modules from any location
values: List of path names (up to 512 bytes)
separators: Comma
takes effect: After you edit your onconfig file and restart the database server.
