Purging data
You can manually purge data that belongs to an XP array or data that is older than the current specified
date. XP Performance Advisor can also automatically purge data for you. Purging of data eventually
increases performance of XP Performance Advisor, as considerable amount of disk space used by
the database is released back to the database.
Manually purging data
You can manually purge performance data that belongs to an XP array or data that is older than the
current specified date.
CAUTION:
Performance data that is purged cannot be recovered. It is permanently deleted from the XP
Performance Advisor database. Hence, purge data only when you are absolutely sure that the data
is no longer required. Also, XP Performance Advisor's activities such as, drawing charts and collecting
data might be impacted when either the manual or auto purge is in progress.
Alternatively, if you want to archive data before purging it, use the archival export functionality. For
more information, see “Archiving data” on page 160.
