Use the MAXLOGIN configuration setting to limit the maximum number of simultaneous user session connections to Essbase Server. This number includes multiple instances of the same user. For example, one user with five open Excel worksheets connected to the same Essbase Server uses one port but five sessions.
You can adjust the value of MAXLOGIN to match computer resources or to more closely manage concurrent ports and user sessions. A concurrent port is used for each unique combination of client computer, Essbase Server, and login name. See the Oracle Essbase Technical Reference.
