Class PurgeManagerBean

java.lang.Object

org.rhq.enterprise.server.purge.PurgeManagerBean

All Implemented Interfaces:

PurgeManagerLocal

public class PurgeManagerBean
extends Object
implements PurgeManagerLocal

A manager for purge. It's mostly used from the DataPurgeJob.

Purge operations should happen in (relatively) small, transaction-bounded chunks. This is to avoid transaction timeouts as a single delete query might fully lock a table for quite some time, thus preventing data coming from agent reports from being inserted.

Method Detail

purgeAvailabilities

public int purgeAvailabilities(long oldest)

Description copied from interface: PurgeManagerLocal

Purges all availabilities that are old. The oldest time is the epoch milliseconds of the oldest availability that is to be retained. The end time is the time that is examined. No availability row with a null end time will ever be purged.

Specified by:

purgeAvailabilities in interface PurgeManagerLocal

Parameters:

oldest - oldest time (in epoch milliseconds) to retain; older records get purged

Returns:

the number of availabilities that were purged

purgeTraits

public int purgeTraits(long oldest)

Specified by:

purgeTraits in interface PurgeManagerLocal

purgeEventData

public int purgeEventData(long deleteUpToTime)

Description copied from interface: PurgeManagerLocal

Deletes event data older than the specified time.

Specified by:

purgeEventData in interface PurgeManagerLocal

Parameters:

deleteUpToTime - event data older than this time will be deleted

Returns:

number of deleted Events

purgeCallTimeData

public int purgeCallTimeData(long deleteUpToTime)

Description copied from interface: PurgeManagerLocal

Deletes call-time data older than the specified time.

Specified by:

purgeCallTimeData in interface PurgeManagerLocal

Parameters:

deleteUpToTime - call-time data older than this time will be deleted

deleteAlerts

public int deleteAlerts(long beginTime,
               long endTime)

Description copied from interface: PurgeManagerLocal

Remove alerts for the specified range of time.

Specified by:

deleteAlerts in interface PurgeManagerLocal

removeOutdatedOOBs

public void removeOutdatedOOBs(long cutoffTime)

Description copied from interface: PurgeManagerLocal

Remove OOBs for schedules that had their baselines calculated after a certain cutoff point. This is used to get rid of outdated OOB data for baselines that got recalculated, as the new baselines will be 'big' enough for what have been OOBs before and we don't have any baseline history.

Specified by:

removeOutdatedOOBs in interface PurgeManagerLocal

Parameters:

cutoffTime - The reference time to determine new baselines

purgeOrphanedBundleResourceDeploymentHistory

public int purgeOrphanedBundleResourceDeploymentHistory()

Description copied from interface: PurgeManagerLocal

Deletes orphaned bundle audit messages.

Specified by:

purgeOrphanedBundleResourceDeploymentHistory in interface PurgeManagerLocal

Returns:

the number or audit messages deleted

purgeOrphanedDriftFilesInDatabase

public int purgeOrphanedDriftFilesInDatabase(long purgeMillis)

Description copied from interface: PurgeManagerLocal

SUPPORTS JPA DRIFT SERVER PLUGIN This will remove all drift files that are no longer referenced by drift entries. This is a maintenance method to help reclaim space on the backend.

Specified by:

purgeOrphanedDriftFilesInDatabase in interface PurgeManagerLocal

Parameters:

purgeMillis - orphaned drift files older than this time will be deleted

Returns:

number of orphaned drift files that were removed

purgePartitionEvents

public int purgePartitionEvents(long deleteUpToTime)

Description copied from interface: PurgeManagerLocal

Deletes event data older than the specified time.

Specified by:

purgePartitionEvents in interface PurgeManagerLocal

Parameters:

deleteUpToTime - event data older than this time will be deleted

Returns:

number of deleted events

purgeResourceConfigHistory

public int purgeResourceConfigHistory(long deleteUpToTime)

Description copied from interface: PurgeManagerLocal

Deletes resource configuration history data older than the specified time.

Specified by:

purgeResourceConfigHistory in interface PurgeManagerLocal

Parameters:

deleteUpToTime - history data older than this time will be deleted

Returns:

number of deleted configurations
