While it isn’t necessary, you might choose to stop calendar services momentarily to prevent further corruption of the database.
To stop calendar services:
cal_svr_base/SUNWics5/cal/sbin/stop-cal
At a command line, change to the directory where the ics.conf is located:
cd /etc/opt/SUNWics5/config
Specify read-only mode for the calendar database:
caldb.berkeleydb.readonly=”yes”
When you have completed editing the ics.conf file, restart Calendar Server:
cal_svr_base/SUNWics5/cal/sbin/start-cal
You must restart the services in order for the ics.conf changes to take effect.
