In
the message text: dsname
The name of the data set that is not available.

returncode
The hexadecimal return code from the ENQ macro. See z/OS MVS Programming: Authorized Assembler Services Reference EDT-IXG for
more information on the hexadecimal return code from the ENQ macro. Note: The
return code will most likely be a X'04', which indicates
that the data set is being used by another address space, job, or
started task.

Operator response
If the return code was X'04', determine
which address space, job, or started task is using the data set by
issuing the following command:D GRS,RES=(SYSDSN,dsname)
If
applicable, wait for the data set to become available. If waiting
for the data set to become available is not applicable, or for return
codes other than X'04', contact the System Programmer and
provide this information for instructions on how to proceed.

System programmer response
See Operator Response. See the return
code information listed for the ENQ service in z/OS MVS Programming: Authorized Assembler Services Reference EDT-IXG and
take action accordingly. Considering the output provided by the D
GRS command, take one of the following actions:Wait for the data set to be released.
