Tuxedo 8.1/9.1 - Client Hangs When Using Un-Self-Described Buffer And Length=0

(Doc ID 777436.1)

Last updated on JANUARY 19, 2018

Applies to:

Oracle Tuxedo - Version 8.1 to 9.1
Information in this document applies to any platform.


This is just an application coding miss as follows.

The client calls tpcall() with CARRAY buffer, and the server application returns buffer with length=0.
The client will hang (or return with blocking timeout) with the following ULOG errors:

LIBTUX_CAT:6031: ERROR: Unable to pre-process buffer before tranmission. Error code(4/3616)
LIBTUX_CAT:1286: ERROR: tpreturn could not send reply TPEINVAL - invalid arguments given
