6162.0. "TCPIP_SINK Missing......" by SNOTTY::BARRY (Ploppy Sir, Son of Ploppy) Mon Nov 07 1994 07:33

Hi All,

I know this problem has been reported before but I cannot find advice on
how to solve my particular problem......

We manage customer networks and I have symptoms of the following nature :

VMS V5.5-2	UCX V2.0	MCC V1.3

We have a tool which keeps an eye on MCC and the system and this is reporting
that the MCC_TCPIP_SINK process is missing.........

I am receiving Indeterminate alarms for all the SNMP devices on this
platform, these alarms check for change of "ifoperstatus" attribute.
Each alarm fires with an error message of :

"Internet communications device error %SYSTEM-F-IVADDR, invalid media address"

When issuing the mcc command :

MCC> show mcc 0 tcpip all attr

I am getting a response and the values associated with this AM.

When issuing the mcc command :

MCC> show mcc 0 tcpip sink all attr

I am getting no response.

When I manually run the TCPIP_SINK executable it seems to run but then
as soon as I issue the "show mcc 0 tcpip sink" command detailed above,
I get the prompt returned to me as the executable stops running.

I have noticed that the BIND database server and its associated entries
have disappeared from UCX and am not sure whether this is related or just
another problem to add to the list.

I have tried the following corrective action so far :

--> Couldn't find a startup procedure for the TCPIP sink.
--> Restarted MCC by running the STARTUP_BMS procedure.
--> Re-enrolled the TCPIP AM via MCC.
--> Re-booted the machine.

If there are any further questions that have to be answered in order for
someone to suggest any further actions then I will do my best to answer.

Thanks in advance

6162.1Help Please........SNOTTY::BARRYPloppy Sir, Son of PloppyTue Nov 08 1994 04:405
Anyone's help greatly appreciated.........

This is a problem with an MCC platform monitoring a CUSTOMER network !!

6162.2maybe a ucx pb ?PRSSOS::BONNAFEGuy BONNAFE - CSC FranceTue Nov 08 1994 09:1111
	It looks like a UCX pb. "%SYSTEM-F-IVADDR, invalid media address"
	is most of the time due to a dupplicate address on the network. Is your
	UCX ok ? are you able to ftp or telnet somewhere ? Can you ping your
	DECmcc station from somewhere ?
	What do you mean by :
>>>	I have noticed that the BIND database server and its associated entries
>>>	have disappeared from UCX ???
	Are you still able to communicate with your bind server ? Ping it ?

	Guy.
6162.3Further questionsSNOTTY::BARRYPloppy Sir, Son of PloppyWed Nov 09 1994 10:2522
Hi Guy,

What I meant by that statement was that the bind database that was previously
present in UCX is now no longer there........

This is because I am now not able to ping the bind server and in fact, I cannot
ping anything !!

It is apparent now that there is a combination of problems with this box,
mostly coming back to fact that no TCPIP communication is being allowed(
probably a UCX config problem).

What I really need to know is how this TCPIP_SINK is actually started,
does it get started by the MCC_STARTUP_BMS procedure or is it a special
case ??

If I know this then when I have solved the IP communication problem, I
will be able to assess whether I have an MCC related problem aswell.

Thanks in advance

	The MCC_TCPIP_SINK process is created when a GETEVENT command is
	issued ( on SNMP entities ). You can generate a GETEVENT directive
	either automatically by creating/enabling an alarm rule or a notify
	request, or manually by issuing a getevent command through the FCL
	interface.

	In the second case, the process disappears as soon as the getevent 
	command is completed ( receipt of an snmp trap for example ). In the
	first case, ALARMS FM or NOTIFICATION FM post a new getevent 
	directive in such a way that a data structure is always available
	for the next event. This way, the MCC_TCPIP_SINK process looks like
	a permanent process.

	This is fully ( and better ) documented in the TCP/IP SNMP AM
	documentation.

	Guy.
6162.5Cheers.....SNOTTY::BARRYPloppy Sir, Son of PloppyThu Nov 10 1994 05:1313
Guy,

Thanks for that, it makes it a lot clearer......

My next question is, presuming that I have got a UCX problem in that this
platform cannot talk to anything using IP, could this affect the integrity
of the TCPIP SINK ??

Would this UCX problem mean that the TCPIP SINK cannot run and therefore
the process would never be present.........OR would the TCPIP SINK run
but just never work properly ??

6162.6PRSSOS::BONNAFEGuy BONNAFE - CSC FranceMon Nov 14 1994 04:5511
	Don't know. When the tcpip sink starts, it tries to open 2 sockets
	on the ucx driver ( check with $ucx show device_socket command ).
	If for one reason ucx doesn't work properly and these sockets cannot
	be created, I assume that the process just exits ( or exits when
	it tries to actually use its sockets ). Should be answered by
	someone owning the code.
	By the way, my advice is to have ip/snmp up and running first, and
	then to test mcc features. Even this way it won't be so easy ...

	Guy.
6162.7Good NewsSNOTTY::BARRYPloppy Sir, Son of PloppyMon Nov 14 1994 05:5010
The problem is solved.

UCX had been "tampered" with and was not working at all. Once
I configured UCX properly I managed to talk using IP and then
, miraculously, the TCPIP SINK sprung into life. Looks like
all the problems were caused by the UCX configuration settings !!

Thanks for your help and advice.
