How are licenses allocated?

The license manager server allocates licenses based on the concept of a session. A session is defined differently for Windows and UNIX.

Windows NT and 2000:

A session is defined by the unique combination of user name and host (machine) name.

For example, a user logged into Windows machine with ArcEditor installed can open numerous ArcEditor sessions and only check out one ArcEditor license.

UNIX:

A session is a combination of user name, host (machine) name, and display name.

For example, on UNIX if you start the Arc application, it will take a license. Then, if you "su" to a different user name, the next time you invoke the Arc application, the license manager will check out another license.

Licenses will be allocated based on two criteria:

  1. Whether a session is local (process running on your local machine), remote (process running on a remote machine on your network) or a batch process.

  2. If the user name, host name, or display name (UNIX only) changes.

License allocation is not affected by the location of ARCHOME or SDEHOME or the location of your working directory.
