Sun Java System Calendar Server 6.3 Administration Guide

ProcedureTo Configure a Server as Both a Front-end and a Back-end

  1. On every server, log in as an administrator with permission to change the configuration.

  2. Change to the /etc/opt/SUNWics5/cal/config directory.

  3. Save your old ics.conf file by copying and renaming it.

  4. Edit the ics.conf parameters as shown in the following table:




    For every front-end server, set the value to “y” if you want all plug-ins starting with cs_ to be loaded into the cal-svr-base/SUNWics5/cal/bin/plugins directory.

    Set to “n”, to load only the CLD plug-in, the name of which is found in


    Set this parameter to "yes".

    To load all plug-ins, set the parameter to "*".

    If you want to load only the CLD plug-in, set this parameter to the name of the plug-in,"calendarlookup".


    This parameter specifies whether calendars are to be distributed across multiple back-ends (set value to “directory”), or calendars are to be stored on the same server on which Calendar Server is installed (set value to,“local”, which is the default value).


    Enable DWP by setting this parameter to "yes"


    The default port is “59979”. This port number must be the same for all front-end and back-end servers.


    This is a multi-valued parameter. Create one ics.confparameter for each back-end server in your Calendar Server deployment. The value of this parameter is the back-end server hostname. The server name must be fully qualified and be resolvable by your Domain Name Service (DNS) into a valid IP address. The server name must be identical and fully qualified in both the parameter name and the value.

    For example:""""

    Set the default DWP server name used by the system if the user or resource LDAP entry does not have an icsDWPHost attribute. The server name must be fully qualified and be resolvable by your DNS.

    For example:


    The hostname where the Directory Server is installed. The default is “localhost”(on the same server as the front-end).


    The hostname where the LDAP user preferences are stored. If you do not keep the user preferences in a separate LDAP host, then it should be set to the same value as local.authldaphost.


    Enable ENS by setting this parameter value to "yes".


    Server alarms must be enabled ("1") on the back-end servers.


    The alarm dispatcher should be enabled ("yes") on the back-end servers.


    The notify service should be enabled ("yes") on back-end servers.


    The automatic archive backup service should be enabled (value set to "yes"on the back-end systems.


    The automatic hot backup service should be enabled (value set to "yes"on the back-end systems.

  5. Save the file as ics.conf.

  6. Restart Calendar Server.
