This chapter describes the pre-installation tasks that you must complete before you can install Oracle Communications Instant Messaging Server.
The 32-bit and 64-bit Java Development Kits (JDKs) must be installed before installing Instant Messaging Server or any of its components. Install both JDKs, rather than the JRE, on your Instant Messaging Server hosts.
See "Required Software" for information about Java version requirements for the various Instant Messaging Server components.
To get the Java software, go to the Java SE Downloads at:

Instant Messaging Server uses a directory server to store and access data for individual users, groups, and domains.
If your site does not currently have Directory Server deployed, and you need to install it, see the Oracle Directory Server Enterprise Edition documentation at:
http://docs.oracle.com/cd/E29127_01/index.htm
Prior to installing and configuring Instant Messaging Server, you must also prepare the directory server schema by running the comm_dssetup.pl script. This script, which is provided as part of the Instant Messaging Server software, adds the necessary schema to the directory. See "Preparing Directory Server" for more information.
To understand the schema that is used by Instant Messaging Server, refer to Unified Communications Suite Schema Reference.
