This is one of those questions that should be directed to your site support group and the CICS support specifically. We do not know the application, nor the environment, nor why you are wanting to "reread" an extrapartition TDQ, so there's not much we can say. There are program commands available using the SP (System Programmer) interface of CICS that would allow your code to close and open the TDQ. However, such commands are usually restricted at sites as some of the SP commands could cause serious CICS problems if used incorrectly. It is possible that ATI (automatic transaction initiation) could help you as well -- but we don't know and cannot say; only someone in your site support group should be helping you.
