Disk and Memory Space Requirement

To install CA OM Web Viewer, you need at least 150 MB of free space in your computer's temp folder for the installation.

• On UNIX or USS, the system temp folder is normally /tmp
• On Windows, the user's temp folder is used.

  For example: C:\Users\USERID\AppData\Local\Temp.

  The user’s temp folder location can be found by typing echo %temp% at the command prompt.

CA OM Web Viewer requires 500 MB to 1 GB of disk space and 1 to 2 GB in main memory. For multiple users, more space is needed.

No formula can be used to calculate the required memory for CA OM Web Viewer because the memory usage depends on:

• Number of users
• Login user roles
• User runtime activities

For each Admin user, Advanced user, and Basic user, there are substantial differences in the memory consumption. The possible memory range is from 500 KB to 1 MB per user at runtime.

Note: For information about changing memory settings in your Java Runtime Environment, see the following sections.
