AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.
Backup and restore configuration parameter reference
Backup and restore configuration parametersThese topics describe the configuration parameters that you use with the ON-Bar, ontape, and archecker utilities.
The archecker utility configuration parameters and environment variableThese topics describe the AC_CONFIG environment variable and the configuration parameters that you use with the archecker utility.
AC_TIMEOUT configuration parameterUse the AC_TIMEOUT configuration parameter to specify the timeout value for the onbar and the archecker processes if one of them exits prematurely.

AC_TIMEOUT configuration parameter

Use the AC_TIMEOUT configuration parameter to specify the timeout value for the onbar and the archecker processes if one of them exits prematurely.

ac_config.std value: UNIX™: 300; Windows™: 300
units: seconds
takes effect: When the onbar-v command starts

The AC_TIMEOUT configuration parameter was introduced to avoid onbar and archecker processes waiting for each other indefinitely if one of them exits prematurely, thus avoiding the creation of an orphan and zombie process during data server initialization.
