CLOSE ACB FOR applname FAILED, CODE= returncode ERROR= acberflag

Explanation

TSO/VTAM issues this message when CLOSE ACB failed during the termination of a TSO session with application program applname.

returncode provides information about the cause of the failure and is one of the following register 15 values:
Value
Meaning
4 (X'04')
One or more ACBs were not successfully closed. Depending on the type of error, the OFLAGS field can indicate that the ACB is closed even though the CLOSE has failed (for example, the ACB might never have been opened).
8 (X'08')
One or more ACBs were not successfully closed. Inspect the ERROR field for the cause of the failure. Another CLOSE macro can be used.
12 (X'0C')
One or more ACBs were not successfully closed. Another CLOSE macro cannot be issued.
acberflag is the value set by VTAM® in the ERROR field of the ACB. See the z/OS Communications Server: IP and SNA Codes for a description of acberflag.
  • A nonzero value in this field provides additional information about the cause of the failure.
  • If acberflag is 0, this indicates that the operating system rejected the close.

System action

The session is terminated. Other processing continues.

Operator response

Save the system log for problem determination.

System programmer response

Use the system log and the values of returncode and acberflag to assist you in correcting the problem. For more information about the CLOSE macro, see z/OS Communications Server: SNA Programming.
