IRCLEAN is a tool that will delete persistent application data. Used mainly to clear out any suspected corruption that can occur when an improper application shut down occurs. Can also be used to clear some internal data.
Syntax:
irclean [ full | partial | vproc <vproc output file name> | dispatch | aim | tsv ]

Additional Info
Of the above file descriptions here are some common terms explained:
Store and Forward (SAF) related files are used by the Prognosis SAF facility (search Help for SAF for details) so that no data is lost when network links go down etc.
Persistence files store binary data that PROGNOSIS has gathered in order to start up more quickly and to automatically re-load thresholds, database collections and so on when it starts up.
Static Configuration files are persistence files for configuration data.
It should be noted that:
* IRCLEAN may cause losses and gaps in monitoring data for various elements and particularly for Availability data;
* IRCLEAN removes all evidence and diagnostics that might identify the root cause of a problem. (However if a problem persists after the IRCLEAN then diagnostics will soon become available again).
* PROGNOSIS will take longer to start up immediately after running IRCLEAN;
* After IRCLEAN all thresholds and databases that were running before will have to be started again manually (same as a Prognosis Cold re-start).
The use of IRCLEAN without advice from support is not recommend as it can lead to unexpecteded data loss. If in doubt, please contact support.
