The protection of updates of normal files is done as I understand it by ENQ.
As I remember, feature EDIF was added to the product MIM to offer the same kind of protection to members of PDSs. Is this kind of functionality now part of base zOS code? The scenario is: Job A is a low priority job run by group X which scans a library using DISP=SHR,DSN=whatever. Job B is a low priority job run by group Y which updates members in the same library using DISP=OLD,DSN=whatever(membername). The question is: Is it safe for group B to use DISP=SHR? ----------------------------------------- The information contained in this communication (including any attachments hereto) is confidential and is intended solely for the personal and confidential use of the individual or entity to whom it is addressed.
