Is it possible to set the JMS Driver of MQClient sending a message to the remote queue stores messages locally in case of remote host unavailability ?
What other mechanism can we use when a remote MQServer is unaivailable when MQ JMS Client is sending ?
In Weblogic word there is a feature called SAF allow the JMS Client to store locally JMS msg until remote host is up again . |

No.

If you're using a supported version of WMQ (v6 or later), your WMQ admin can define a CCDT to provide an alternative server in the event of failure. Your code will need to reconnect when the connection drops, but it should be doing that anyway.

WMQ clients are fully sync and there's no local component to store messages.

In MQ 7.0.1, the clients can reconnect on their own under the covers.
In MQ 7.0, there can be local storing of messages for MQ Clients -"read ahead" gets.

I guess just use that?
Otherwise Vitor's suggestion of automatically going to MQ Server 2 if MQ Server 1 is n/a is probably what you want.

Point taken, but this doesn't help the OP who's trying to do puts.
