Resolution

There are two System Parameters which are responsible for the number of usessions a user can have at one point in time in TPX:

1. In the fifth panel of the SMRT titled "System Features" you can choose the value of parameter "ACCESS". If this is set to 'SINGLE' or 'PASS' each user can have only one session at a time.
2. In case that parameter "ACCESS" is set to 'MULTIPLE' you still can influence the number of parallel sessions a user can have. This is done in parameter "Maximum Sessions" in the first panel of SMRT titled "Performance Parameters". This value restricts the number of Sessions TPX can have active. This is by default set to '00000' which means that no limit is in place. If necessary you can restrict the number of sessions to a specific number. These settings are valid for the complate TPX-region.
