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.
PLOG_OVERFLOW_PATH configuration parameterThe PLOG_OVERFLOW_PATH parameter specifies the location of the file that is used during fast recovery if the physical log file overflows.

PLOG_OVERFLOW_PATH configuration parameter

The PLOG_OVERFLOW_PATH parameter specifies the location of the file that is used during fast recovery if the physical log file overflows.

The file is plog_extend.servernum and by default located in $INFORMIXDIR/tmp. Use the full path name to specify a different location for the file with the PLOG_OVERFLOW_PATH parameter.

onconfig.std values: On UNIX™: $INFORMIXDIR/tmp
On Windows™: None
takes effect: When the database server is brought up (shared memory is initialized)
