Setting comment through tuxedo oracle transaction manager

Question

Hi
We are using tuxedo functions tx_* for managing transactions to oracle database.
Generally we can specify a comment with Oracle's commit statement which allows identification of transaction in case of issues.
My question is that how can we specify the commit comment with tx_commit() function from a tuxedo server.
Thanks

Tariq,
There isn't any COMMENT parameter available on the Tuxedo tx_commit() or tpcommit() call. However, you courld call the Tuxedo userlog() function just before calling tx_commit(), and this will write whatever comment you want to the Tuxedo ULOG call. When userlog() is called within a tranasction the line written to the ULOG includes 3 hexadecimal numbers representing the Tuxedo GTRID (global transaction ID.) If an error occurs during the transaction, Tuxedo may also write messages of its own to the ULOG, and these messages will also show the GTRID.
The TMTRACE environment variable can also be used to write information about the calls made during a transaction to the ULOG. For example,
export TMTRACE=*:ulog:dye
will cause information about all ATMI calls to be written to the ULOG.
