Error description
ISTTSCAF is issuing sense 08410000 when processing a Bind request. The network address is still in use by a previous session that had just ended.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of VTAM applications. * **************************************************************** * PROBLEM DESCRIPTION: Session setup fails with 08410000 * * sense code due to incomplete cleanup * * of a prior session. * **************************************************************** * RECOMMENDATION: * **************************************************************** The problem may be summarized as follows: 1. A BIND is sent to a VTAM application. 2. An UNBIND for the same session is also sent to the same application. 3. The UNBIND attempts to verify that the PCID in the FMCB extension matches the PCID in the UNBIND's CV60, but the BIND process has not yet saved the PCID in the extension, so the UNBIND fails with a sense of x'80050000'. 4. The BIND continues and sets up the SLU side of the session. 5. The negative UNBIND response takes down the PLU side of the session, including the use of the element address. 6. Sometime later, when a subsequent session is being established, the same element address is reallocated, but the FMCB from the SLU side of the earlier session is found and the sense of x'08410000' is set for the session setup attempt.
Problem conclusion
ISTTSCAF is updated to save the PCID in the FMCB extension so it will be there earlier and therefore any subsequent UNBIND will succeed.
