Hi

Hercules locks the DASDs listed in its configuration file with both a write and a read lock. The write lock is justified. The read lock could (I am arguing "should") be relaxed.

In this way, some of the external utilities could still work while Hercules is running (e.g., DASDLS).

Thanks

Marco

This is a Windows problem, dasdls works fine while Hercules is running on Fedora Linux.

Allow utilities r/o access to dasd opened r/w by Hercules:

Resolves GitHub Issue #355.

NOTE: commit also includes a fix to prevent a new shadow file from being erroneously created when the batch utility is only requesting read-only access to existing shadow files.
