IDB Space Low
Event/notification name IDBSpaceLow
What triggers the notifications?
One of the following events:
• The difference between the maximum and current size of all CDB extension
files drops below Filename Tablespace Size Limit Threshold [MB] (default
maximum for filenames.dat file, 250 MB)
• Free space on any of the disks containing the IDB drops below Disk Free
Threshold [MB] (default, 50 MB).
• The difference between the maximum and current size of all DC directories
drops below DCBF Size Limit Threshold [MB] (default, 250 MB).
By default, Data Protector checks the IDB Space Low condition once a day.
Default message level Major
Message displayed
Data Protector Internal Database is running out of space.
IDB Tablespace Space Low
Event/notification name IDBTablespaceSpaceLow
What triggers the notifications?
A lack of free space for the IDB tablespaces. More than Tablespace Used
Threshold [%] (default, 85%) of the allocated space is already used.
By default, Data Protector checks the IDB Tablespace Space Low condition
once a day.
Default message level Major
Message displayed
Tablespace <Tablespace_name> is running out of space.
Note:
It is mandatory to check the Data Protector software event log on a regular
basis and check for eventual IDB events. An administrator might consider
setting up notifications sent by e-mail allowing prompt action on incoming
notifications.
Note:
Additional information about IDB maintenance tasks is available in the
white paper "HP Data Protector IDB Purge Best Practices," which can be
