IGD057I

Explanation
The dynamic allocation for SMS data set failed
because that data set was not available. The data set was either a
storage management subsystem: source control data set (SCDS);
active control data set (ACDS); or
communication data set (COMMDS).

The return code and reason code are from dynamic allocation.
In
the message text: dsname
The data set name.
rc
The return code.
rsnc
The reason code.

System action
The system issues either message IGD040D if the
error occurred with SCDS or ACDS; or messages IGD070D or IGD072A if
the error occurred with COMMDS.

Operator response
Tell the system programmer about this message,
and ask how you should respond to the IGD040D, IGD070D, or IGD072A
message that follows.

System programmer response
Use the dynamic allocation codes and
the logrec data set to determine why the data set was not available. z/OS MVS Programming: Authorized Assembler Services Guide and z/OS DFSMSdfp Diagnosis may
also be helpful for determining the error.
