Sun Java Communications Suite 5 Installation Guide

Post-Installation Calendar Server Configuration

After you install the Calendar Server software, you must configure it. This step was previously performed as part of the installation process, but has now been separated out of the installer.

After you install Calendar Server, you must configure Calendar Server as follows:

  1. Run the Directory Server Setup script ( to configure Sun Java System Directory Server.

  2. Run the Calendar Server configuration program ( to configure your site’s specific requirements and to create a new ics.conf configuration file. For a description of the parameters in the ics.conf file, see Configuration Parameters (ics.conf) File in Sun Java System Calendar Server 6.3 Administration Guide.

    The script is located in the /opt/SUNWcomds/sbin directory, and the utility is located in the /opt/SUNWics5/cal/sbin directory.

    There are some configuration settings and changes that the Java Enterprise System installer and Calendar Server configuration utility ( do not make. You must manually make changes to the following items:

    • DWP and CLD Configurations. Edit the ics.conf file so that the CLD cache option is enabled. This cache stores the DWP host server information for calendar users and thus reduces calls to the LDAP directory server.

    • Default Time Zone. If your default time zone is not Americas/New York, change it by editing the ics.conf file. You also need to change it in the /opt/SUNWics5/cal/bin/html/default_user_prefs.xml file so that it is in sync with the ics.conf file.

    • Client-side Rendering. Calendar Server performs client-side rendering by downloading the XSLT processing to the end user’s browser, which in turn reduces the processing that must be done by Calendar Server. Calendar Server downloads the XSLT processing only if the browser is capable of rendering the XSLT processing. In the current release, this applies only to Internet Explorer 6.0. Edit the ics.conf file to make this performance improvement to client-side rendering.

    • Setting for tmpfs. Edit the tmpfs setting for performance enhancement.

    For more information on these changes, see the Sun Java System Calendar Server 6.3 Administration Guide.
