APAR status

  • Closed as program error.

Error description

  • LUA application issues INITSELF but does not receive a BIND from
the PLU application. An NSPE flows reporting a 08010000 from
the PLU host because a previous PLU-SLU session was not cleaned
up and therefore still active.

Local fix

  • clean up all sessions manually on the appl. host.

Problem summary

  • * USERS AFFECTED:
* All users of DLUR where the host application resides on
* a different node than the SSCP.
*
* PROBLEM DESCRIPTION:
* Unable to activate a DLUR LU-LU session (receiving NSPE
* with sense 08010000) after a session was terminated
* with TERM-SELF (from an LUA appplication using
* RUI_WRITE) after the SSCP had been taken over after the
* LU-LU session had been activated and the new SSCP was
* not the PLU.
*
* PROBLEM SUMMARY:
* After a DLUS takeover/giveback while a LU-LU session is
* active with a host application residing on a different
* node than the SSCP, the DLUS does not have enough
* information to contact the host APPL to UNBIND the LU-LU
* session. When the local application issues a TERM-SELF,
* the DLUS  is unable to contact the host APPL to notify
* it to send an UNBIND but does send DACTLU and ACTLU to
* the DLUR. The local application, later issues INIT-SELF
* to begin a new session but the DLUS sends an NSPE with
* sense code 08010000 indicating that the host APPL is
* still in session.

Problem conclusion

  • Internal code has been altered to issue an UNBIND
type 0x09 (Hierarchical Reset) when DACTLU 0x01
(normal) is received on a DLUR LU when the LU-LU
session is active.

Temporary fix
