max users - jobs/tasks (maxuser parm in IEASYSxx)
max users - TSO users (usermax parm in TSOKEYxx)
both should be in the system parmlib
system command to change tso user max
modify tso,usermax=xxxx |

A word of caution before you increase that maxuser number. For each allowed user specified at the MAXUSER parameter an amount of 50 bytes of CSA storage in subpool 231, key 0 below 16 MB will be allocated at system initialization time. Increasing the users may result in CSA shortages.You may also want to increase the CSA size
