Yes you can, code MQPUT and after that an MQGET WAIT in the IMS application, like you would do in a standalone or batch program. Simply search for MQPUT with MQGET WAIT example (e.g. Search for COBOL example: Getting a message using the wait option). It will be any non IMS sample, you just need to link with CSQQSTUB. You have to do the MQOPEN after each IMS input message, because for security and integrity reasons in an IMS transaction the MQ connections are closed when the transaction instance ends (e.g. next GU IOPCB). However, this is bad behaviour because the IMS region is blocked for other work - consider increasing number of IMS regions to process those transactions. In addition any lock aquired by DB calls will be held longer which might cause deadlocks. So at best do read without locking before and updates after it and then commit asap to keep locking windows small.
