Caché System Administration Guide - InterSystems Documentation

Identifying Users
is considered a “user request.” Information about implementing a SOAP session is available in SOAP
Session Management in Using SOAP and Web Services with Caché.
Processes started by the user start routine (^%ZSTART or the older ^ZSTU) are another special case.
The process running ^%ZSTART has no parent process. Therefore, a login is performed for the user
ID, User Startup, before ^%ZSTART is called. Processes started by the Job command from
^%ZSTART have this user ID. If you prefer, call $System.License.Login(UserId) from ^%ZSTART
to change the user ID. This procedure means that ^%ZSTART can start as many as one less than
maxconn background processes and only consume one license. If, according to the license terms and
conditions, these processes should have a separate license (for example if they drive a piece of laboratory
equipment that requires a separate license), you are required to call $System.License.Login(UserId)
to obtain a license for an appropriate user ID.
Finally, it is important to understand that Caché does not distinguish background processes and count
them differently. If a user process starts another process, that child process counts as one more against
the user’s overall maximum limit of processes.
