Tuxedo Workstation Clients Hang On OpenVMS (Doc ID 1452147.1)

Last updated on MAY 02, 2012

Applies to:

Oracle Tuxedo - Version 11.1.1.2.0 and later
Information in this document applies to any platform.

Symptoms

There are three symptoms for how this problem presents itself:

1)On OpenVMS Tuxedo clients are created by a control/parent process. If the control process is then killed with stop/id some workstation clients will hang.
After the hang new workstation clients are unable to connect to Tuxedo as the workstation handler appears to be deadlocked by the hang..  A hard kill recovery is required to continue.

2)A similar symptom also occurs without using stop/id by just setting the Tuxedo TMTRACE logical before booting the application.

3) Finally, without using stop/id or TMTRACE, TBEBLOCK/TPESYSTEM/TPELIMIT errors are received by the client applications using tpacall() under heavy load with the following messages:

175551.mymachine!?proc.826510770.2068770496.0: LIBWSC_CAT:1078: ERROR: Unable to read message from temporary file
175551.mymachine!?proc.826510770.2068770496.0: LIBWSC_CAT:1029: ERROR: Unable to retrieve stored reply
