We are experimenting some performance issues with the MQ Adapter. For example, we are seeing that the MQ Adapter takes from 10 to 100 ms in reading a single message from the queue and sending to the tuxedo service. The Tuxedo service takes 80 ms in its execution so there is a considerable waste of time in the MQ adapter that we cannot explain.
Also, we have looked a lot of rollback transactions on the MQ adapter, for example we got 980 rollback transactions for 15736 transactions sent and only the MQ adapter is involved in the rollback. However, the operations are executed properly. The error we got is
135027.122.hqtux101!MQI_QMTESX01.7636.1.0: gtrid x0 x4ec1491f x25b59: LIBTUX_CAT:376: ERROR: tpabort: xa_rollback returned XA_RBROLLBACK.
I am looking for information at Oracle site, but I have not found nothing. Could you or someone from your team help me?
