Need help on using Tuxedo with Oracle 8

Question

Hi friends,
I wrote a simple tuxedo server with embedded sql that has only the task to insert
a string passed by the client into a table in oracle DB.
The Server is logged on to the database correctly during tmboot. When I start the
client the service function will be invoked and it returns TPSUCCESS. But somehow
my sql statements are ignored. No record is added to the table and I got no sql errors.
Here is my service function (AUTOTRAN=Y):
void INSERT(TPSVCINFO *msg){
EXEC SQL insert into ABC values ('some data');
EXEC SQL COMMIT WORK;
if (SQLCODE != SQL_OK){
tpreturn(TPFAIL, 0, msg->data, 0L, 0);
tpreturn(TPSUCCESS, 0, msg->data, 0L, 0);
Thanks in advance.
Kevin

Hi Kevin,
Oracle Docs has the following to say abt SQL Error -36:
ORA-00036 maximum number of recursive SQL levels (string)
exceeded
Cause: An attempt was made to go more than the specified
number
of recursive SQL levels.
Action: Remove the recursive SQL, possibly a recursive
trigger.
Pl check if u have some triggers on the table... and also
determine
the level of their nesting... That shld probably solve
ur probs.
Good Luck

Hi, thanks for your answer.
But I am not sure of the error message...is the error
code what
I got an ORA error code or something else (e.g. why -36
and not
36)?
Please have a look to my source code.
Hope you can give me more information.
Thanks in advance

Also... print out the remainder of the sqlca structure.
You will have
error text in that structure describing what the actual
error is.

Hi Manoj,
thanks for your answer.
I added an extra SQLCODE check after the insert andget following
error:
"SQLCODE = -36"
Do you know how to find out what the error is stangfor?
Thanks

Hi Kevin,
Could u pl put an extra SQLCODE (or sqlca.sqlcode)check
after the INSERT statement
as shown in the modified code and try...
Currently the check verifies the sqlcode of the COMMIT
statement and not the INSERT
statement executed just before.
