Wrong translation commond when I write Tuxedo Service to use Informix Database

Question

Old Environment:
DB : Informix Dynamic Server Version 7.31.UC5
Tools : INFORMIX-ESQL Version 7.24.UC8
MIDDLE : Tuxedo 6.4 patch 341
New Environment :
DB : Informix Dynamic Server Version 9.30.FC1
Tools : IBM Informix CSDK Version 2.80,
IBM Informix-ESQL Version 9.52.UC2
MIDDLE : Tuxedo 8.0 patch 135
Event :
My old tuxedo service had wroted to communicate with Informix Database by
XA transaction. In my service code have to
prepare informix statement by command
' EXEC SQL PREPARE p_roll FROM "ROLLBACK WORK" ' And in my old environment it's
workable until I upgrade my environment.
My old tuxedo service can compile in new environment but when i try to test
service by ud32 tool the result is error "A syntax error has occurred". After
I check my code and receive statement at Database host I found some thing does
not correct.
I send to prepare ' ROLLBACK WORK ' but at database host received ' ROLLBACK WORKRK"
' that unknown command to database.
I try to write my small new code to test PREPARE command of Informix ESQL/C
without to build to Tuxedo Server, It's can work correctly.
If you had found the same case , Please advise me too.
Thanks you very much for your advise.

Answer 1

If ud32 reported a syntax error, then your service was never called.
Normally, a service running under XA control should not issue transactional SQL
statements. Begins and Rollbacks are issued from the transaction manager, not the
application code.
Can you post the Tuxedo message catalog number, and your ud32 script, as well as
your environment variables?
