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.
