This is what the Syncpoint options are for - to allow you to commit() and rollback().

Hi jeff...

I am reading a bit on syncpoint, however am i right to understand that it cannot be used with the Browse option?

Am getting an error thrwo with the followign options.
int openOptions = MQC.MQOO_FAIL_IF_QUIESCING | MQC.MQOO_BROWSE | MQC.MQOO_INPUT_AS_Q_DEF;

getOptions.options = MQC.MQGMO_FAIL_IF_QUIESCING | MQC.MQGMO_WAIT |MQC.MQGMO_SYNCPOINT;

Please could you help with the suitable options.....

THanks Jeff.

A browse is not a destructive get.

Hey...thanks very much....i was doing something wrong... it worked well with

int openOptions = MQC.MQOO_INPUT_EXCLUSIVE + MQC.MQOO_FAIL_IF_QUIESCING;

&

getOptions.options = MQC.MQGMO_WAIT + MQC.MQGMO_CONVERT |MQC.MQGMO_SYNCPOINT;

Thank You!!

You probably don't want to INPUT_EXCLUSIVE, unless you have a very good reason.
