Step 2 Create the HDS database on the machine.
Note For information about running Setup for an Admin Workstation, see the Cisco
ICM Enterprise Edition Installation Guide.
Use the ICMDBA tool to determine the size of the database and to create the
database. (See “Estimating the Size of a Database” and “Creating a Database”
earlier in this chapter.)
When a Database Nears Capacity
ICM software has automatic checks to prevent the central database from
becoming full:
Warning message. When the central database begins to approach its capacity,
ICM software issues a warning message. By default this occurs when the database
is 85% full, but this value can be configured.
Automatic purge. If you select the Automatic Purge option when you install the
Logger software, the ICM software automatically deletes the oldest historical
data, if it exceeds the retention period, when the central or HDS database nears its
capacity. If the data has not exceeded the retention period, it does not get deleted.
By default, automatic purge occurs when the database is 90% full, but you can set
the percentage when you set up the Logger. You can also set the retention period
for data when you set up the Logger.
Note Refer to the Cisco ICM Enterprise Edition Installation Guide for more on
purging information from databases.
The automatic purge ensures that the database can never become completely full.
The worst that can happen is you begin to lose older historical data.
