DFHAP0001 0C1 AKEA at FFFFFFFF in DFHSJITL during CICS TS startup

Question & Answer


Question

Why am I receiving an abend0C1 in DFHSJITL when I initialize CICS Transaction Sever for z/OS (CICS TS)? I see the following message:

DFHAP0001 CICSAPPL An abend (code 0C1/AKEA) has occurred at offset X'FFFFFFFF' in module DFHSJITL.

I am also seeing abends 0999 ASRA and AKEH in the dump table and trace.

Answer

The dump of CICS reveals that there was a RUNAWAY (0999) detected, followed by the S0C1 ABEND. But the most interesting finding is in the JVM output files. The output shows that there is a directory that cannot be found or created. This specification was for the WORK_DIR for the JVM server.

The JVM output shows:

 2017/02/05 03:52:55.056266 UTC JVMServ1 D ÝLE-Thread-0¨ ÝDFHSJSC:13158¨ 
  *Exc*: perrorEncoded(), change_to_dir - @Exit 2: EDC5129I No
  such file or directory. (errno2=0x0594004D)

  *Exc*: ipt_control_loop(), Failed to redirect output  

Once the correct path was added to the WORK_DIR parameter in the JVM profile, the abend 0C1 in DFHSJITL no longer occurred. See JVM server options in the CICS TS documentation for more information about the WORK_DIR option.
