The system failed to create the restartable PDSE address space SMSPDSE1 because the maximum number of address spaces would have been exceeded. This error occurred either during IPL processing or when a VARY SMS command was issued.
If the error occurred during IPL processing, PDSE processing is performed by the nonrestartable address space SMSPDSE. If the error occurred as a result of a VARY SMS,PDSE1,ACTIVATE command or a VARY SMS,PDSE1,RESTART command, PDSE processing which was being performed by SMSPDSE1 is delayed.
If the error occurred as a result of a VARY SMS,PDSE1,ACTIVATE command or a VARY SMS,PDSE1,RESTART COMMAND, reissue a VARY SMS,PDSE1,ACTIVATE command. If the problem persists, contact the system programmer.
The problem might have been caused by a temporary strain on workload. Consider increasing the installation-defined maximum number of address spaces by increasing the value specified on the MAXUSER parameter in the IEASYSxx parmlib member. Alternatively, consider having the operator free one or more address spaces by identifying jobs or TSO/E sessions that can be stopped.
