Installation and Configuration Guide for DCL SNAP-IX

Preparing to Install the BEA WebLogic Java Adapter for Mainframe for DCL SNAP-IX

Before you install the BEA WebLogic Java Adapter for Mainframe (WebLogic JAM) software, you must complete the following tasks.

- Download WebLogic JAM for DCL SNAP-IX from the Web

- Determine the installation method

- Determine your hardware requirements

- Verify the WebLogic JAM software requirements

- Choose a BEA Home directory

Download WebLogic JAM for DCL SNAP-IX from the Web

An evaluation copy of WebLogic JAM for DCL SNAP-IX is available for download from the BEA corporate Web site at http://commerce.bea.com/downloads/weblogic_server.jsp#jam. When you download WebLogic JAM for DCL SNAP-IX, you get a built-in 30-day evaluation license. Because WebLogic JAM for DCL SNAP-IX is included in the WebLogic JAM license, it will be updated when you update the WebLogic JAM license.

Determine the Installation Method

On the Solaris 7 or 8 platform, the installation may be accomplished using either a graphical (InstallAnywhere-based) interface or a console (text mode) interface.

After the installation is complete, the installation may be validated using supplied installation verification samples.

After the WebLogic JAM is installed, it may be removed or uninstalled. Similar to the installation interface, the uninstall interface may be either console or graphical.

Determine Your Hardware Requirements

Before you begin installing the WebLogic JAM software, verify that your system meets the size requirements for installing and running the WebLogic JAM components.

Size Requirements for Installing WebLogic JAM for DCL SNAP-IX

The following requirements must be met for the WebLogic JAM to be successfully installed.

- Platform Requirements

A certified Solaris 7 or 8 platform is required for the CRM (see the BEA WebLogic Java Adapter for Mainframe Release Notes for the platform requirements for the WebLogic JAM Gateway).

- WebLogic JAM Gateway

- Hard Disk Drive Requirements

In addition to the requirements for a WebLogic Server installation, an additional 13 MB of free storage space is required to install WebLogic JAM Gateway.

- Memory Requirements

For a Windows or Unix system, adding a basic WebLogic JAM configuration to a WebLogic Server installation does not significantly increase the system RAM requirements. But, increasing the number of service definitions will increase the memory requirements for WebLogic JAM Gateway.

- CRM

- Hard Disk Drive Requirements

Approximately 14 MB of free storage space is required to install the WebLogic JAM CRM.

- Memory Requirements

The Solaris DCL SNAP-IX CRM requires an approximate memory size of 9 MB. This will increase with the number of regions configured for the CRM.

Verifying WebLogic JAM Software Requirements

Verify that the following software is installed before you install WebLogic JAM:

- JDK

JDK 1.3 or greater is required by the InstallAnywhere installation product to install the WebLogic JAM software. Version 1.3.1 of the JDK is installed with WebLogic Server 7.0. If you are installing WebLogic JAM without first installing WebLogic Server, set your PATH environment to the appropriate JDK directory. If you do not have the JDK installed, use the console method of installation.

- WebLogic Server 7.0

WebLogic Server 7.0 is required for proper operation of WebLogic JAM if you are installing the WebLogic JAM Gateway. If you attempt to install WebLogic JAM without installing WebLogic Server, a warning will display, but you can continue installing WebLogic JAM.

Choosing a BEA Home Directory

During the installation of WebLogic JAM, you are prompted to choose an existing BEA Home directory or to specify a path for a new BEA Home directory convention. For example, you can install only one instance of WebLogic JAM 5.1 in a BEA Home directory, but that BEA Home directory may also contain an instance of WebLogic JAM 5.0.

Creating More Than One BEA Home Directory

Although it is possible to create more than one BEA Home directory, we recommend that you avoid doing so. In almost all situations, a single BEA Home directory is sufficient. There may be circumstances, however, in which you prefer to maintain separate development and production environments, each containing a separate product stack. With two directories, you can update your development environment (in a BEA Home directory) without modifying the production environment until you are ready to do so.
