Sun Java System Calendar Server 6.3 Administration Guide

ProcedureTo Enable Hot Backups for a Calendar Server 6.3 System

  1. Log in as an administrator with permission to change the configuration.

  2. Stop Calendar Server services by issuing the stop-cal command.

  3. At a command line, change to the directory where the ics.conf is located:

    cd /etc/opt/SUNWics5/config

  4. Enable hot backups by setting the following ics.conf parameter to "yes":

    caldb.berkeleydb.hotbackup.enable="yes"

  5. Specify the directory path for the hot backup directory:

    caldb.berkeleydb.hotbackup.path=
   /var/opt/SUNWics5/hotbackup_directory

    The default hot backup directory for Calendar Server is /var/opt/SUNWics5/csdb for Solaris and /var/opt/sun/calendar/csdb for Linux. The Communications Suite installer puts the archive and hot backup directories in the csdb directory by default because it is the convenient subdirectory that is known to the installer.

    Note –

    It is highly recommended that the Calendar Server administrator needs to put the archive and hot backup in a different disk or volume or partition than the csdb directory because of the size issues.

    The number of archive and hot backup directories is configurable. So, if you choose to have six of each archive and hot backup directories, it means that they might have 6 + 6 + 1 copies of your live database in the csdb directory. The csstored utility calculates the size of the required archive and hot backup based off of the size of the contents of the csdb directory and the physical disk that csdb is located on.

    The archive and hot backup directories are installed inside the csdb directory by default for convenience. But, it should be located in a directory outside of csdb for a real life deployment.

    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 6, Configuring Calendar Server 6.3 Software for High Availability (Failover Service).

  6. When you have completed editing the ics.conf file, restart Calendar Server:

    cal-svr-base/SUNWics5/cal/sbin/start-cal
