Introduction › ENQ and RESERVE Propagation Methods

ENQ and RESERVE Propagation Methods

You can select either of these methods of ENQ and RESERVE propagation:

• Automatic propagation of all requests that have a scope of SYSTEMS (PROCESS=ALLSYSTEMS).
• Propagation of only the requests that you designate (PROCESS=SELECT).

Note: We recommend using PROCESS=ALLSYTEMS rather than PROCESS=SELECT: data integrity exposures may occur with PROCESS=SELECT.

No matter which method you choose, you can create a QNAME list to provide GDIF with detailed processing instructions. A QNAME list is a series of statements that tell GDIF how to handle ENQ/RESERVE requests based on the major name; that is, QNAME.

You also can provide GDIF with supplemental and more specific processing instructions in an exempt list. With the exempt list, for example, you can prevent a request from being propagated if it is issued by a certain job or is for a certain resource.
