Configuring database size
You can increase the HP XP7 Performance Advisor database size based on the disk space available
on the management station, where HP XP7 Performance Advisor is installed. It can be a manual
or automated process, where HP XP7 Performance Advisor checks the available disk space and
increases the database size appropriately. The database size can be configured under DB
Configuration/Purge that is enabled by default when you click PA and DB Settings+Database
Manager in the left pane.
Initially, when HP XP7 Performance Advisor is installed and performance data collection is not yet
scheduled, the following message is displayed on the DBconfiguration/Purge screen:
nl
Important: No Collections are being performed. Performance collection
should be started for Auto purge forecasting
.
After the performance data collection is initiated and the database size increases, HP XP7
Performance Advisor displays a forecast message on the DBConfiguration/Purge screen. The
forecast message indicates the approximate duration by when auto purge starts if the current data
collection trend continues.
The minimum system disk space that can be allocated for the database is 3 GB (default), and the
maximum disk space that can be allocated is 300 GB.
IMPORTANT:
Irrespective of whether you configure the database size manually or automatically,
once the database size increases, you cannot revert to the previous set database size.
Automatically increasing database size
You can configure HP XP7 Performance Advisor to automatically verify and allocate the disk space
available on your management station to the database.
Click PA and DB Settings+Database Manager in the left pane and select the Auto Grow check box
under DB Configuration/Purge. By default, this functionality is enabled for HP XP7 Performance
Advisor.
IMPORTANT:
Ensure that at least the available disk space is greater than 3 GB for Auto Grow
functionality to work.
When
the database grows to X% of the allocated size, where X is a minimum threshold value
configured
in the purgeparameter.properties file, Performance Advisor automatically checks
for
the available disk space on the system and does one of the following:
•
If the available disk space is greater than 3 GB, HP XP7 Performance Advisor automatically
increments the database size by 2 GB and displays the following message on the Event log
screen:
nl
DB size auto grew to X GB
.
Where, X refers to the current disk space allocated for the database. For example, if the
available disk space is greater than 21 GB + 3 GB (disk space needed for HP XP7 Performance
Advisor to initiate Auto Grow + 3 GB), the allocated database size is automatically increased
by additional 2 GB.
