14.1 Online data purge
The measurement data collected by 7signal Sapphire can take lots of disk space. Sapphire provides a tool
for online removal of old measurement data.
Configuring the data purge requires knowledge about DB2 database, so a Database Administrator
should always be involved when setting up measurement data purge process.
Online data purge requires a set of additional database indexes, which can take reasonable amount of disk
space. Make sure that there is at least 30% free disk space on the database partition before upgrading to
Sapphire 7.3 or 8.1.
It is preferred to execute the purge daily basis, in conjunction with the backup. See chapter 14.3 for more
information about the backup process.
