We have an MQ server installation and our application connects local y to the QM and hence - QMBEGIN, MQGET and MQ PUT with syncpoint commit worked as expected ( to avoid any data loss) .
Now we have to migrate our application to connection to a remote QM using MQ client connection . Hence MQBEGIN with syncpoint control is not supported.
The application uses MQ c/c++ API in Linux system and has no other resource manager as it is not required.
How can the unit of work be managed with MQ client Version 8.0.0.5 ?
What are possibilities for installation of a transaction manager in a distributed env.
I have read - that Extended MQ client needs to be enabled . I it sufficient or Do we need to install an XA compliant transaction manager like ' BEA Tuxedo MQ adapter ' or Websphere Application Server . |

| If no other RM is involved, why are you using MQBEGIN? |

Mark is correct. If it is just a local transaction, ie. the only resource manager involved in the transaction is MQ, then you don't need the Extended Transaction client, nor do you need MQBEGIN or a Transaction Manager. Just issue:
MQGET(MQGMO_SYNCPOINT)
MQPUT(MQPMO_SYNPOINT)
MQCMIT()
and MQ will do all the hard work for you.
Cheers,
Paul.
