With DECmcc VMS T1.2.4, my customer is encountering
a behaviour modification with DECmcc V1.2 contra DECmcc V1.1 :
- In version V1.1 , when we Double-Click on a global
entity, the AM receives the
SHOW <class> * ALL ID (ex SHOW APBX .TOTO LINE * ALL ID)
for sub-classes which have DYNAMIC = FALSE in the MSL.
The SHOW <class> * ALL ID for sub-classes with DYNAMIC = TRUE
is only sent to the AM when we Double-Click on the
subclass itself and not on the global class.
- In version V1.2 , when we Double-Click on a global
entity, the AM receives the
SHOW <class> * ALL ID for all sub-classes
whatever DYNAMIC may be in the subclass MSL definition
(FALSE or TRUE).
I read in the TK Release notes p3-14 paragraph 3.2.2
" The AM or the FM must support the SHOW <class> * ALL ID for each
entity class. The IMPM issues this directive when performing
the "lookinto" operation ".
My question is :
1) Does this mean the IMPM behaviour change from V1.1 to V1.2
they have observed is normal ?
2) Is there any way to come back to a V1.1 behaviour ?
3) For subclasses containing only one instance in the class
in some entities like a SINK or a LOG for example ?
- Does the AM/FM still has to support the
SHOW ENTITY TOTO SINK * ALL ID ?
- If yes, what is the recommended implementation
in the AM ?
* Return an identifier which has no meaning as there
is only one instance in this class ?
* Leave to the agent the responsibility to return
this identifier ?
* Other ?
Best Regards

is only one instance in this class ?
* Leave to the agent the responsibility to return
this identifier ?
