The application that /owns/ the *DTAQ object should know how to [re]create the object. If the application does not have a documented procedure to do that, then one would hope for comments in the source code. If neither, then as was already mentioned, there is the Retrieve Data Queue Description (QMHQRDQD) API to determine the attributes:

Be sure to consider also that the object owner and private authorities might be of interest. DSPOBJD and DSPOBJAUT, or respective APIs. Since a MOVOBJ should be capable to move the *DTAQ even while it is damaged, after the appropriate ownership is established, GRTOBJAUT REFOBJ() REOBJTYPE() can be used to effect the same authorities on the new object from the old\moved object.

An application should probably be generally capable of recognizing that its data queue object is damaged and then to: effect dump of the object, log the incident, delete the damaged object, and then automatically to recreate the data queue with the required ownership and authorities [see above for move and grant].
