Dataspace too large – IEFUSI limit reached
The Builder received a response from the table manager,
CIUTABM, that it was unable to obtain the amount of storage requested
for the MVS data space, because MVS exit IEFUSI has imposed a limit
on address space size.
The Builder is terminated.
Either decrease the data space size specified on
the PARM field of the EXEC statement in the job, or ask your MVS system programmer to increase
the IEFUSI limit. Rerun the job.
