Restoring queue manager data
To restore a backup of a queue manager’s data:
- Ensure that the queue manager is not running.
- Find the directories under which the queue manager places its data and its log files, using the information in the configuration files
- Clear out the directories into which you are going to place the backed-up data.
- Copy the backed-up queue manager data and log files into the correct places.
- Update the configuration information files (or equivalent Registry entries on Windows).
Check the resulting directory structure to ensure that you have all the required directories.
See Directory structure (Windows systems) and Directory structure (UNIX systems) for more information about WebSphere MQ directories and subdirectories.
Make sure that you have a log control file as well as the log files. Also check that the WebSphere MQ and queue manager configuration files are consistent so that WebSphere MQ can look in the correct places for the restored data.
If the data was backed up and restored correctly, the queue manager will now start.
For circular logging, backup the queue manager data and log file directories at the same time as this should allow a consistent set of queue manager data and logs to be restored.
For linear logging, we recommend that you backup the queue manager data and log file directories at the same time. However, it is possible to restore only the queue manager data files if a corresponding complete sequence of log files is available.
