08C

Explanation
A program issued a SCHEDULE macro to schedule a
service request block (SRB). The system detected an error while processing
the macro. Register 2 contains the SRB address. Register 3 contains
the return address of the issuing program. A hexadecimal reason code
in register 15 explains the error: Code
Explanation
04
The address specified in field SRBASCB of the service request
block (SRB) does not point to a valid address space control block
(ASCB).
08
The ASCB specified in the SRB has the ASCBFAIL flag set on. The
flag indicates that the address space is ending.
0C
The specified STOKEN does not represent the same address space
as the ASCB specified in the SRB.
10
A feature was requested using the SCHEDULE macro but there are
no online processors with the specified feature.
14
An entry point was requested using the SCHEDULE macro but an incorrect
feature indicator was specified.
18
A feature was requested using the SCHEDULE macro but an non-valid
feature indicator was specified.
1C
An internal error occurred during schedule processing.
20
A program issued a SCHEDULE macro to schedule an SRB with the
SPTOKEN option while holding a lock higher than or equal to the DISP
lock in the locking hierarchy. You cannot use the SPTOKEN option while
holding a lock equal to or higher than the DISP lock.
24
DISABLED was specified on the SCHEDULE macro, but the caller was
not disabled.
28
The caller was in AR ASC mode but did not specify this via the
SYSSTATE macro.
2C
The SRB was not in common storage.

System action
The system abnormally ends the program that issued
the SCHEDULE macro. The system may write a logrec data set error record.

Operator response
If the system programmer asks for an SVC dump,
set the following SLIP trap: SLIP SET,COMP=08C,ACTION=SVCD,END

System programmer response
For reason code 10, resubmit the job
on a processor complex that has the feature installed. For reason
code 24, you must obtain the CPU lock before using the SCHEDULE macro.
For reason code 28, specify SYSSTATE ASCENV=AR prior to issuing the
SCHEDULE macro in order to ensure the macro expansion will be correct.
For reason code 2C, ensure the SCHEDULE macro is being used with an
SRB that is in common storage. For all other reason codes, do
the following: Ask the operator to set a SLIP trap to obtain an SVC
dump.
In the system trace, find the system service event
(SSRV) entry for abend X'08C'. Diagnostic data in this entry
is as follows: The return address for the issuer of the SCHEDULE macro is in
the ADDR column.
The input SRB address is in the UNIQUE-1 column.
The target address space ASCB address is in the UNIQUE-2 column.
The STOKEN representing the target address space is in the UNIQUE-3
column.

Use the address in the ADDR column of the SSRV entry
to identify the module that issued the SCHEDULE macro. For an installation-provided module, continue diagnosis with the
module.
For an IBM® module, search
problem reporting data bases for a fix for the problem. If no fix
exists, contact the component group associated with this module at
the IBM Support Center. Provide
all problem data collected and, if available, the logrec data set
error record.
