Subject: Method to determine if a library is in use
I have a utility that checks if an app is use by doing a WRKOBJLCK OBJ(XXX) OBJTYPE(*LIB).
I recently had this fail.
One app addlible XXX.
Opens files in XXX
Execute a process, finish.
WRKOBJLCK OBJ(XXX) OBJTYPE(*LIB) shows no locks.
But within the XXX library, there were object locks remaining.
Never realized you could have object locks and the library containing the objects is no longer is the library list.
Searching for better method to determine object locks since WRKOBJLCK OBJ(XXX) OBJTYPE(*LIB) is no longer valid.
