Explanation
JES3 may have issued one of the following messages
because of the indicated error: IAT1601
The user is trying to perform I/O to a data set that is closed. An
incorrect IATYDAT was found on the data buffer block (DAT) queue.

IAT1602
One of the following control blocks either (1) could not be validated
or (2) contains incorrect data: IATYDAT, IATYDMC, IATYDSB or IATYDSS.
IAT1603
A JES3 module passed, as a parameter to IATDMEB, a code that requested
an incorrect data management function.
IAT1604
A start I/O operation in the user's storage returned an error
code.
IAT1605
A start I/O operation in the user's storage returned an error
code.
IAT1606
IATDMEB found an incorrect unprotected buffer (IATYDAT) address
or the associated IATYDMC address was incorrect.
IAT1607
IATDMEB could not allocate an unprotected buffer.
IAT1609
One of the following occurred: When module IATDMEB or IATSIAD attempted to set up a data management
WAIT, the module found a data management function already waiting.
When module IATDMEB or IATSIAD attempted to set up a subsystem
interface WAIT, the module found a subsystem function already waiting.

IAT1610
During ENDREQ processing, a request for macro IATYJDS failed.
IAT1611
The JES3 SSVT was either (1) incorrect or (2) could not be found.
IAT1612
The SYSOUT class to be allocated is not alphanumeric.
IAT1614
A failure occurred while processing a started task or TSO logon
internal reader data set.
IAT1803
An attempt to move data from a JES3 protected buffer in the JES3
auxiliary address space to a user storage unprotected buffer failed.
IAT6700
During deallocation, when attempting to update the JDSENTRY, the
module could not find a job data set (JDS) entry.

set.
IAT6707
At deallocation of the external writer data set, the module could
not find an output scheduling element (OSE).

A permanent I/O error occurred on an output data set.
IAT6711
A SSISERV macro sent incorrect data to the global processor; the
request could not be serviced.
IAT6309
A failure has occurred during an MVS™ LOAD
or BLDL of a JES3 input service module.

If none of these messages appear, JES3 found
an incorrect IFGACB, IATYDSS, or IATYDSB control block or received
an error return code as a result of either a SJFREQ request or a
multi-system core buffer request.

System action
Depending on the error, the system ends either
the job step or the user address space.

System programmer response
If messages accompany this abend,
register 3 in the dump points to a copy of the data set status block
(DSS). A hexadecimal reason code explains the error. Use this reason
code to determine the cause of the error. If the reason codes report errors from IATDMCB, requestors
of multi-system core buffer information will experience a delay in
getting a response.  Following the delay, the information reported
will include only the records that have been written to spool. The
core buffer information will not be reported.  To repair this processing,
request an IPL of the main that received the 1FB Abend.Code

Programmer response
If the problem occurred in an I/O operation,
correct any I/O errors in your program. Then rerun the job.
If
JES3 issued message IAT6309, correct the cause of the LOAD or BLDL
failure. Then rerun the job. Otherwise, notify your system programmer,
supplying a SYSABEND dump.
