Restriction: ON-Bar does not use the TAPEDEV, TAPEBLK, TAPESIZE, LTAPEBLK, and LTAPESIZE configuration parameters.
ON-Bar on IBM® Informix® uses the following configuration parameters:
| Configuration parameter | Purpose |
|---|---|
| ALARMPROGRAM parameter | Specifies a script that handles alarms For ON-Bar, set this script to log_full.sh to automatically back up log files when they become full. |
| ALRM_ALL_EVENTS parameter | Causes ALARMPROGRAM to execute every time an alarm event is invoked. |
| BACKUP_FILTER parameter | Specifies the location and name of an external filter program used in data transformation. |
| BAR_ACT_LOG parameter | Specifies the location and name for the ON-Bar activity log file. |
| BAR_BSALIB_PATH parameter | Specifies the full path and name of the XBSA shared library provided by the storage manager to communicate between ON-Bar and the storage manager. |
| BAR_DEBUG parameter | Specifies the level of debugging information to display in the ON-Bar activity log file. You can dynamically update the value of BAR_DEBUG in the onconfig file during a session. |
| BAR_DEBUG_LOG parameter | Specifies the location and name of the ON-Bar debug log |
| BAR_IXBAR_PATH parameter | Specifies the location where the ON-Bar ixbar boot file is created. You can change the file name and path |
| BAR_HISTORY parameter | Specifies whether the sysutils database maintains the backup history |
| BAR_MAX_BACKUP parameter | Specifies the maximum number of processes per onbar command |
| BAR_NB_XPORT_COUNT parameter | Specifies the number of shared-memory data buffers for each onbar_d worker or child process |
| BAR_PERFORMANCE parameter | Specifies whether timestamps and transfer rates of storage-manager operations are recorded in the activity log. |
| BAR_PROGRESS_FREQ parameter | Specifies in minutes how frequently the backup or restore progress messages display in the activity log |
| BAR_RETRY parameter | Specifies how many times ON-Bar retries a backup, logical-log backup, or restore operation if the first attempt fails |
| BAR_XFER_BUF_SIZE parameter | Specifies the size in pages of the buffers that the database server uses to exchange data with each onbar_d worker or child process |
| ISM_DATA_POOL parameter | Specifies the volume pool that you use for backing up storage spaces (ISM) |
| ISM_LOG_POOL parameter | Specifies the volume pool that you use for backing up logical logs (ISM) |
| LTAPEDEV parameter | For ontape, specifies the tape device where logical logs are backed up For ON-Bar, specifies whether to back up logs. If this configuration parameter is set to /dev/null on UNIX or NUL on Windows, the backup utility is not able to back up the logical logs. |
| RESTARTABLE_RESTORE parameter | Turns restartable restore on or off |
| RESTORE_FILTER parameter | Specifies the location and name of an external filter program that restores transformed data to its original state |
