IEF300I

Explanation
A serious error occurred either while the external
writer was attempting to obtain a SYSOUT data set from JES2 or JES3
or to dynamically allocate a SYSOUT data set received from JES2 or
JES3.
In the message text: jobname
The jobname assigned to the external writer processing the SYSOUT
data set.
xxxx/yyyy
The error code received by the external writer. Interpret the
error code as follows: If yyyy = 0000, the IEFSSREQ macro instruction
was issued, and xxxx is the return code (in register
15) from IEFSSREQ macro processing.  See the description of the subsystem
options block (SSOB) in z/OS MVS Data Areas in z/OS Internet
Library at http://www.ibm.com/systems/z/os/zos/bkserv/ for
the explanation of the register 15 return codes.
If yyyy = FF00, the IEFSSREQ macro instruction
was issued, and xxxx is the value of the SSOBRETN
field in the subsystems option block (SSOB). See the description of
the SSOB in z/OS MVS Data Areas in z/OS Internet Library
at http://www.ibm.com/systems/z/os/zos/bkserv/ for
the explanation of the return codes in SSOBRETN. These codes are listed
under ‘Process SYSOUT Data Sets Return Codes’.
If yyyy is any value except 0000 or FF00, SVC
99 was issued; yyyy is the error reason code (S99ERROR),
and xxxx is the return code in register 15 from
SVC 99 processing. See z/OS MVS Programming: Authorized Assembler Services Guide for
the explanation of the SVC 99 error reason codes and return codes.

System action
The external writer closed the output data set
on device dev and ends.

System programmer response
If the error recurs and the program
is not in error, look at the messages in the job log for more information.
Search problem reporting data bases for a fix for the problem. If
no fix exists, contact the IBM® Support Center. Provide the
JCL and the SYSOUT output for the job.

Programmer response
Respond as required for the error code that
appears in the message. When the problem is corrected, enter the START
XWTR command again.
