You will need to add the parameter 'MAXUSER ####' to one of the start-up parameter files.
I would suggest to add it to the 'User Initialization Procedure' – which by default is member $ACINIT found in your TESTEXEC library.
The syntax for the statement to be added in the $ACINIT member is as follows:
After a recycle of the region, the N11302 message now reflects the new value -
N11302 MAXUSERS LIMIT NOW SET TO 1000.
Also, when you display the option using the MAXUSER command, the message N11301 will reflect the new value:
N11301 CURRENT MAXUSERS LIMIT IS 1000, NUMBER OF USERS IS 1.
