2437.0. "AM's " by CCIIS1::ROGGEBAND (_ �hili��e _) Thu Feb 27 1992 06:48

Hi All,

    I'm back with more questions :
    
1) Has anyone developped AM's with an integrated event sink ? How is the event
   thread started ? How is the object access function synchronized between
   threads ? Do they explicitely use the DECthreads package ? Are there any
   plans to document inter-thread communications?

2) Can child entity classes be added to existing Global entities (assuming
   that the corresponding AM code is implemented) ? In other words, can I
   write an AM for an entity called Bridge x Coffe-Machine y ?

3) What information is available regarding the status of DECmcc vs OSI/NMF?
   Where is the development effort located ? Are there any documents available
   on the net ?

    Thanks all,
    
    Philippe.

You should contact Jean Lee (TOOK::JEAN_LEE) for more details if she doesn't chime in here soon. >2) Can child entity classes be added to existing Global entities (assuming > that the corresponding AM code is implemented) ?

2437.2	Answer to 2 is "YES"	CHRISB::BRIENEN	DECmcc LAN and SNMP Stuff...	`Thu Feb 27 1992 17:32`	13
	>2) Can child entity classes be added to existing Global entities (assuming > that the corresponding AM code is implemented) ? In other words, can I > write an AM for an entity called Bridge x Coffe-Machine y ? > Yes, an AM can be written that just supports BRIDGE x COFFE-MACHINE y. Just set up the dispatch tables (and augment the BRIDGE class) correctly and you're home free. This is similar to REGISTRATION FM supporting BRIDGE x Reference Attributes (i.e., dispatch table magic). The SNMP (and I believe, DNA5) AM supports the adding of new children dynamically (you don't have to write a new AM, just put the new information in the dictionary and presto: instant support...
2437.3	Check out the Example FM	NANOVX::ROBERTS	Keith Roberts - DECmcc Toolkit Team	`Thu Feb 27 1992 17:40`	9
	Take a look at the Example FM mcc_examples:example.* The Example FM augments the Sample AM to provide a response timer capability. The PONG directive calls the Sample AM to see how long it takes the entity to respond. /keith

	Philippe, this is currently a project underway based on OSI/NMF. The goal is to have DECmcc able to interoperate with other vendor Management Systems based on OSI/NMF recommendations. If you need more information send me a mail or call me (DTN 828-6142). Regards, Jean-Jacques
2437.5	remember to register	TOOK::CALLANDER	MCC = My Constant Companion	`Tue Apr 07 1992 12:30`	6
	one last word of caution when considering the extention of an existing global entity, is that you must register the children. Without the registration process (the DSSR registry not the "register" verb) there will be no way to control/coordinate the efforts of different groups/organizations.
