00A

Explanation
A program attempted to schedule an asynchronous
or installation exit by branch-entering the stage 2 exit effector.
The stage 2 exit effector detected a problem.
A hexadecimal
reason code in register 15 explains the error: Code
Explanation
0004
IQETCB did not point to a valid TCB. A program sets up the IQE
by putting a TCB address into the IQETCB field. The program then branch-enters
the stage 2 exit effector to schedule an asynchronous or installation
exit, passing the address of the IQE.
0008
RQETCB did not point to a valid TCB. A program sets up the RQE
by putting a TCB address into the RQETCB field. The program then branch-enters
the stage 2 exit effector to schedule an asynchronous or installation
exit, passing the address of the RQE.
000C
The program branch-entering the stage 2 exit effector did not
hold the local lock for the home address space.
0010
The program branch-entering the stage 2 exit effector did not
have addressability to the address space in which the asynchronous
or installation exit was to be dispatched.
0014
The program branch-entering the stage 2 exit effector was not
in primary or secondary address space control (ASC) mode.

System action
The system abends the program that branch-entered
the stage 2 exit effector. The system may also write a logrec data
set error record and an SVC dump.

Operator response
If the system programmer asks for an SVC dump,
set the following SLIP trap: SLIP SET,COMP=00A,ACTION=SVCD,END

System programmer response
  Do the following: If an SVC dump or a logrec data set error record is not written
with the abend, ask the operator to set a SLIP trap to obtain an SVC
dump.
Use the address in register 14 at the time of error to identify
program that branch-entered the stage 2 exit effector. 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 for the module at the IBM Support Center. Provide, if
available, the SVC dump and the logrec data set error record.
