Prerequisites for installing

This topic describes the prerequisites for installing BMC Atrium Single Sign-On.

• • Limitation
  • Access and permissions
  • Disk space requirements
  • Memory requirement
  • Log file memory requirements

Limitation

Do not deploy BMC Atrium Single Sign-On on an NFS-mounted file system.

Access and permissions

• If the runtime user of the BMC Atrium Single Sign-On web container instance is a non-root user, this user must be able to write to his own home directory.
• (Microsoft Windows) You must have administrator privileges.
• (UNIX) You can be any user. However, root privileges are required to set up auto-startup of the services.

Disk space requirements

This section contains information about prerequisite storage space requirements for installation and log files.

Before installing BMC Atrium Single Sign-On, you must have at least the following available disk space:

• (Windows ) 650 MB
• (Linux ) 750 MB
• (Oracle Solaris ) 850 MB

Memory requirement

If you are installing BMC Atrium Single Sign-On on an external Tomcat server, 1024K of RAM is required.

If you are installing BMC Atrium Single Sign-On on an external Tomcat server with Tomcat 7 and JDK 1.7, increase memory an additional 20% for a minimum of 1.2 MB.

Log file memory requirements

An additional 7-10 GB of space is recommended for log file growth, depending on the volume of users and products integrating with the BMC Atrium Single Sign-On server.

To manage log file storage space effectively, perform the following tasks:

• Delete the debug log files periodically, especially if the debug level is set to message.
• Check the .access and .error log files periodically in the logs directory.
• Consider configuring the log rotation to delete the oldest log files.
