About Calendar Server 7

Calendar Server 7 is the Oracle next-generation Calendar Server, which is based on the new standard for calendar access called CalDAV.

Calendar Server 7 is a newly designed server and replaces the existing Calendar Server 6.  Calendar Server 7 operates in a very different manner from Calendar Server 6.  Though both servers use the standard iCal format for data, Calendar Server 6 supports only the WCAP protocol for data access, making it usable only with Oracle-supplied clients and connectors. 

Calendar Server 7 supports the standard CalDAV access protocol, which makes it usable with Apple iCal, iPhone, Thunderbird Lightning, and any other CalDAV clients.

Calendar Server 7 U1 added support for "WCAP7", which is supported in Convergence 2.

Getting Started

Oracle Communications Calendar Server for CALDAV Clients (Calendar Server 7) is bundled as part of Oracle Communications Unified Communications Suite 7.

For brevity and accuracy, the "Oracle Communications Calendar Server for CALDAV Clients 7" is referred to as "Calendar Server 7" in the Knowledge documents available on My Oracle Support (MOS).

If you are initially installing Calendar Server 7, the best place to begin is with the Installation Guide and Release Notes.

You should not install Calendar Server 7, original release. (This was available in Communications Suite 7, original).  You should install "Oracle Communications Calendar Server for CALDAV Clients 7 Update 1" from "Oracle Communications Unified Communications Suite Version 7 Update 1" (or higher if available).

Upgrading & Migration

Upgrading consists of choosing an upgrade strategy, then upgrading each of the individual servers using that strategy.  The procedure for upgrading individual servers depends on the version of Calendar Server you are currently running. See the following documentation for more information.

It is recommended that both Calendar 6.3 and Calendar 7 have the latest patches applied prior to migration.  This will help to avoid known migration issues already fixed and aid in troubleshooting any new issues which may arise.
Also note that Calendar Server 6.3 Premier Support ended in Oct 2013.  See the Oracle Lifetime Support policy page for more information. It is recommended to migrate to Calendar 8 for continued support.


The Calendar Server 7 System Administrator's Guide contains most of the useful information needed.

Updating to patch -15 (v7. Prerequisites & Information

Review the Calendar Server Release Notes and take note that
  • GlassFish Server 2.1.1
  • Java 6
are listed under "Deprecated and Removed Components and Features for Calendar Server"

Upgrading to Calendar Server requires that you have JAVA SE 7. It is recommended to have latest JAVA 7 update (7u51 or above).
And it requires GlassFish server 3.1.2.x ( or above).

Failure to meet this requirement causes the Calendar Server patch to fail.

Updating to patch -14 Prerequisites & Information

Patch -14 is included as part of Oracle Communications Unified Communications Suite 7 Update 5

Please note that the README and the Documentation for this patch is assuming you are upgrading to Comms Suite 7 Update 5.  If you do not intend to upgrade to Comms Suite 7 Update 5 then, you still need to follow the Calendar 7 upgrade document as instructed.
Please note that installing the comm_dssetup patch is required to make this Calendar patch install successful.
This patch is available in the following platform-specific versions:

118245-25 Solaris sparc
118246-25 Solaris x86
118247-25 Linux

Please also note the MySql changes to charset to be utf8mb4 instead of utf8.

What you need to be aware of:

The documentation for this patch states that you need to be using GlassFish 3, but, if you are not intending to upgrade to Comms Suite 7 Update 5 and if the same Appserver is used for Convergence 2 and CalDav, then, you should remain on Glassfish 2 for now.

Convergence 2 requires using GlassFish 2 and not GlassFish 3, please see the Product Requirements for Comms Suite 7 Update 4 (pdf)

If CalDav is deployed on a different Appserver to Convergence 2, then we recommend you follow the instructions in the upgrade guide to install GlassFish 3.

Please be aware however, that GlassFish 2 is nearing its end of Premier Support at the end of January 2014 and, for this reason, it is encouraged to spend time testing Comms Suite 7 Update 5 using GlassFish 3 to ensure you receive full Support.  Please see the following URL for GlassFish Support here.
