93.0. "Intermittant TCPIP/SNMP entity access?" by ASD::MINTZ (Erik Mintz, MS ZKO3-2/S11, dtn 381-2331) Tue Apr 03 1990 16:18

The following log shows the same command, executed twice back to back.
The first succeeds, the second fails.  The time between command
entry and the error message is almost immediate, so it does not
appear to be a timeout.  Any idea what is going on?

93.1	2 bugs	CSEVEN::DANIELE	SNMP, right here & now.	`Tue Apr 03 1990 17:04`	15
	Erik and I did a bit of investigation over the phone. This is really 2 bugs. The first is that the AM occasionally decides that it has no attributes to send back to TRM. I'll try and track that one down. The second is that what the AM passes back across the interface for "got no attributes" apparently isn't what TRM expects for "got no attributes". This situation is exactly what happens when you ask a Portal for TCP attributes, as documented in the release notes. I hope to have an answer to this one soon. Thanks, Mike
93.2	NOTE: don't use WITH then	GOSTE::CALLANDER		`Thu Apr 05 1990 15:05`	16
	Mike I am interested in knowing what your "got no attributes" equates to... Also note with a problem like this be careful using the TRMs WITH clause support. In the EFT kit there was a problem in the TRM that makes it so that the WITH processing MUST receive back at least one attribute if the FM or AM is signalling a successful response. Note that the results you will see if the AM doesn't return any attributes will be an ILV error, that doesn't make much sence to a user. jill
93.3	1 down...	MKNME::DANIELE		`Mon Apr 09 1990 11:42`	13
	Bug # 1 has been fixed, please see note 97. Bug # 2 is still being investigated. Please note that the error message " %MCC-E-NOENTITY, No corresponding entity instance exists " has NOTHING TO DO with manageable entities. It does not mean, for instance, that XPLORE is somehow unknown or unavailable. This message is presented by TRM when it can't successfully interpret what's encoded in Out_P. Mike
93.4	Quiescence	MKNME::DANIELE		`Tue Apr 10 1990 13:29`	2
	Bug # 2 is now understood, and TRM will support this particular implementation of "empty" by EFT update.
