Backup and restore configuration parameters
These topics describe the configuration parameters that you use with the ON-Bar, ontape, and archecker utilities.
Informix® Primary Storage Manager configuration parameters
The Informix® Primary Storage Manager uses the information in some specific configuration parameters.
PSM_DEBUG configuration parameter
Use the PSM_DEBUG configuration parameter to specify the amount of debugging information that prints in the Informix® Primary Storage Manager debug log if you want to use a debug level that is different from the one used by ON-Bar.

      - Informix® Primary Storage Manager configuration parameters
        The Informix® Primary Storage Manager uses the information in some specific configuration parameters.
        PSM_ACT_LOG configuration parameter
        Use the PSM_ACT_LOG configuration parameter to specify the location of the Informix® Primary Storage Manager activity log if you do not want the log information included in the ON-Bar activity log.
        PSM_CATALOG_PATH configuration parameter
        Use the PSM_CATALOG_PATH configuration parameter to specify the full path to the directory that contains the Informix® Primary Storage Manager catalog tables. These catalog tables contain information about the pools, devices, and objects managed by the storage manager.
        PSM_DBS_POOL configuration parameter
        Use the PSM_DBS_POOL configuration parameter to change the name of the pool in which the Informix® Primary Storage Manager places backup and restore dbspace data.
        PSM_DEBUG configuration parameter
        Use the PSM_DEBUG configuration parameter to specify the amount of debugging information that prints in the Informix® Primary Storage Manager debug log if you want to use a debug level that is different from the one used by ON-Bar.
        PSM_DEBUG_LOG configuration parameter
        Use the PSM_DEBUG_LOG configuration parameter to specify the location of the debug log to which the Informix® Primary Storage Manager writes debugging messages if you do not want the log information included in the ON-Bar debug log.
        PSM_LOG_POOL configuration parameter
        Use the PSM_LOG_POOL configuration parameter to change the name of the pool in which the Informix® Primary Storage Manager places backup and restore log data.
      - Event alarm configuration parameters
        When you set configuration parameters for use with the ON-Bar and ontape utilities, also determine if you need to adjust the ALARMPROGRAM and ALRM_ALL_EVENTS configuration parameters.

  The describes the concepts of data replication using Informix® Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.

PSM_DEBUG configuration parameter

Use the PSM_DEBUG configuration parameter to specify the amount of debugging information that prints in the Informix® Primary Storage Manager debug log if you want to use a debug level that is different from the one used by ON-Bar.

onconfig.std value: Not set. The default value is used.
default value: The value of the BAR_DEBUG configuration parameter is used.
units: One digit to represent the level of debugging information that you want
range of values: 0 = No debugging messages.; 1 = Prints only internal errors.; 2 = Prints information about the entry and exit of functions and prints internal errors.; 3 = Prints the information specified by 1-2 with additional details.; 4 = Prints information about parallel operations and the information specified by 1-3.; 5 = Prints information about internal states in the Informix® Primary Storage Manager.; 6 = Prints the information specified by 1-5 with additional details.; 7 = Prints information specified by 1-6 with additional details.; 8 = Prints information specified by 1-7 with additional details.; 9 = Prints all debugging information.
takes effect: When the onpsm utility starts; When the ON-Bar utility executes commands and reads information that is specified in the BAR_DEBUG configuration parameter; 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 you set the PSM_DEBUG configuration parameter to a valid value that is higher than 0, the Informix® Primary Storage Manager logs debug messages to its debug log.

You can experiment with the debug values to find the right amount of information. Generally, if the PSM_DEBUG configuration parameter is set to 5, the storage manager prints enough information for tracing and debugging purposes.

Settings of 8 and 9 require a large amount of space.

You can also use the PSM_DEBUG environment variable to specify the amount of debugging information that prints in the storage manager debug log for your environment, for example, for a single session.
