Management & Control Services (MCS) and management components can be installed under either Windows or UNIX. The following procedure explains how to install MCS and management components in UNIX environments. You can install using either the default Attachmate HTTP engine or a WebLogic application server. For information about installing in a Windows environment, see Installing MCS and Management Components on Windows.
|If you use WebLogic, your WebLogic domain must exist before you begin the installation. If you need to create a new domain, do so using one of the methods provided by BEA.|

If you perform an installation while logged in as the root user, you can re-assign file ownership for all Attachmate files to another user. You can choose a user name other than the default. If this user does not exist on the system, the installation script creates it for you, and prompts you for group name, home directory, and password. If you specify a user other than the default, you must specify an existing user account for which a home directory already exists. Assigning files to a system user account such as "nobody" or "other" without an existing home directory will prevent the HTTP engine from restarting properly.
If you are not logged on as the root user or if you do not have root-level rights, your installation location may be limited to your own home directory.
To avoid errors associated with attempting to run on a computer with limited RAM or virtual memory, edit attachmateinstalldir/catalina.sh before running the installation. Change the first value in the line
JAVA_OPTS=\"-Xms256m -Xmx256m \"\\
to something smaller, for example,
JAVA_OPTS=\"-Xms32m -Xmx256m \"\\.
If you do not make these changes, you may encounter problems such as being unable to log in to MCS. You can check for associated errors in the synapta_setup.log, such as "unable to allocate memory" or "heap allocation failure."
The Java VM heap size may need to be adjusted to allow for the number of sessions or threads running in your environment. As noted above, this option can be changed in attachmateinstalldir/catalina.sh, either before or after installation.
