At a command line, change to the directory where the ics.conf is located:
cd /etc/opt/SUNWics5/config
Enable hot backups by setting the following ics.conf parameter to “yes”:
caldb.berkeleydb.hotbackup.enable=”yes”
Specify the directory path for the hot backup directory:
caldb.berkeleydb.hotbackup.path= /var/opt/SUNWics5/hotbackup_directory
You might choose to place hot backups on an alternate disk or disk subsystem in case of a hardware failure on the primary disk drive. Doing this might also reduce input-output contention on the primary drive or subsystem.
If you have a high availability (HA) configuration, specify the path as a subdirectory in shared storage (/global/cal/ ). See also, Chapter 7, Configuring for High Availability (Failover Service).
When you have completed editing the ics.conf file, restart Calendar Server:
cal_svr_base/SUNWics5/cal/sbin/start-cal
The calendar services do not need to be stopped to edit the ics.conf file, but you must restart the services in order for the changes to take effect.
