Before you install

Be sure that the requirements for your operating system are met before you begin installation. See IBM® Tivoli® Directory Server version 6.3 System Requirements for information.

Before installing, be sure that the following conditions are met. If these conditions are not met, the installation program will exit.

• If you are upgrading from a previous release (Tivoli Directory Server 6.0, 6.1, or 6.2):

  Use the instructions in Upgrading from previous releases to install Tivoli Directory Server 6.3 and migrate your data. With Tivoli Directory Server 6.3, pre 6.0 versions of servers are not supported and there would be no forceful migration of directory server instances from previous releases (Tivoli Directory Server 6.0, 6.1, or 6.2) since directory server instances of 6.x versions can coexist.

• If you are not upgrading from a previous release of Tivoli Directory Server, and you have an unsupported version of DB2® installed on your computer, and you are installing the full directory server:

  If the DB2 version is earlier than 8, you must remove it. Tivoli Directory Server does not install if these versions of DB2 are present. If you have DB2 version 8 installed, you can leave it on the system; this DB2 version can coexist with the version of DB2 that Tivoli Directory Server installs. If you do not have a version of DB2 on your system, the InstallShield GUI installs it if you choose to install the full directory server.

• The server and the client from Tivoli Directory Server 6.3 can coexist with the following clients and servers:
  • A client from Tivoli Directory Server 6.0, 6.1, or 6.2
  • A server from Tivoli Directory Server 6.0, 6.1, or 6.2
  If any of these are installed, you can leave them installed.

  However, links on AIX®, Linux, and Solaris systems for Tivoli Directory Server 6.3 libraries and commands are not set. If you want to set links to Tivoli Directory Server libraries and commands, use the idslink command. See the IBM Tivoli Directory Server Version 6.3 Command Reference for information about the command.

  On Windows systems, the path is not set to include the directories where the Tivoli Directory Server 6.3 libraries and commands reside. This means that when using the command line, you must type the full path to the command or change to the subdirectory where the command resides before typing the command. Otherwise, a message indicating the failure to find command will be displayed. As an alternative, you can update your PATH environment variable to include the following Tivoli Directory Server 6.3 subdirectories:

  • installpath\sbin
  • installpath\bin
  • installpath\lib

  (For a default installation, installpath on Windows systems is:

  C:\Program Files\IBM\LDAP\V6.3)

  If you have more than one version of Tivoli Directory Server installed and you set the path to find commands for one version of Tivoli Directory Server, you must type the full path or go to the subdirectory where the command resides if you want to issue a command for another version of Tivoli Directory Server.

• If you have the Web Administration Tool from Tivoli Directory Server 6.0, 6.1, or 6.2 installed and you want to migrate it, leave the Embedded WebSphere® Application Server installed with the Web Administration Tool deployed into it. For systems with Tivoli Directory Server 6.0, 6.1, or 6.2 installed, the previous version of the Web Administration Tool will be undeployed, the new version of Embedded WebSphere Application Server will be installed, the new version of the Web Administration Tool will be deployed into Embedded WebSphere Application Server, and the Web Administration Tool configuration files will be migrated. You can uninstall the old version of Embedded WebSphere Application Server later.
• Similarly, if you have White Pages from Tivoli Directory Server 6.1 or 6.2 and you want to migrate it, leave Embedded WebSphere Application Server installed with White Pages deployed into it, and White Pages configuration files will be migrated.
• On Windows systems, if you are installing the proxy server or the full directory server, the Administrators group provided with the Windows operating system must exist.
• On Windows systems, be sure that you have at least 255 MB of free space in the directory specified by the TEMP environment variable or the directory you want to use as a temporary directory. If you use a temporary directory and you are installing any of the corequisite products (Embedded WebSphere Application Server or DB2) be sure that you also have an additional 150 MB in the directory specified by the TEMP environment variable.
• On AIX and Linux systems, be sure that you have at least 300 MB of free space in the /tmp directory or the directory you want to use as a temporary directory. If you use a temporary directory and you are installing any of the corequisite products ( Embedded WebSphere Application Server or DB2) be sure that you also have an additional 150 MB in the /tmp directory.
• On Solaris system, be sure that you have at least 400 MB of free space in the /tmp directory or the directory you want to use as a temporary directory. If you use a temporary directory and you are installing any of the corequisite products (Embedded WebSphere Application Server or DB2) be sure that you also have an additional 150 MB in the /tmp directory.
