Hello!
Sorry for my bad English.
I use one Hercules' instance for Share Device Server.
?
One Hercules' instance should use DASDs with read-write access, the second Hercules' instance should use DASDs with read-only access.
In Hercules' config for second Hercules' instance i define these DASDs as "READONLY FAKEWRITE".
In z/VM's SYSTEM CONFIG i deifne theseDASDs as "RDEV ... SHARED YES MDC OFF".
In z/VM's DIRECTORY minidisks on these DASDs are defined as "MDISK .... MWV ..."
?
Now I start Hercules' instances on the same PC under Windows 10, but in the future Hercules' instances should run on different servers under Linux.
?
These DASDs are used by the DBMS ADABAS. When I make changes in one Hercules instance, the changes are not displayed in another Hercules instance.
But if DASDs with changes are copied to another server where ADABAS is running, without closing the ADABAS nucleus, without rebooting Hercules or re-ipl z/VM, detach-attach DASDs, JUST COPY, then the changes will be visible immediately. ADABAS uses minidisks, but uses its own input/output.
?
§³an i set up DASDs sharing so that changes are visible immediately?
How do I set up shared access to DASDs correctly in my case?
?
Thanks in advance.
