3556.0. "DNA5 logger failing with bytlim error" by SEDSWS::MALLOY () Thu Aug 13 1992 09:58


		Dna5 Event logger
		-----------------


Problem 1
=========
    
I am having problems with DNA5 event logger. Twice it has stop with
the following error message  "exbytm    exceeded  bytlim"

I have increased system account from 60,000 to 131,000 ,still the same problem.

I have again increased the bytlm to now 200,000 . (time will tell)

 ANA/SYSTEM indicates I am picking up bytlm quota from the process which 
	    is starts it.	
	 
	 I have 17 incoming event streams .
	 VAXstation 4000/model 60  56Mb memory  V5.5 Wave 1 

Question:
	  What resources do I need per incoming event stream????



Problem 2
=========


I can restart DNA5 event properly when the system is running.

(DNA5 starts ok during system startup .)

I have to reboot the machine to restart dna5 correctly. (Which is not always 
practical)

++++++++
The DNA5 process starts . MCC_DNA5_EVL process state is HIB.
But main problem is that the object MCC_EVL is not create.

The MCC_DNA5_EVL.log file shows not errors.

I have tried starting Dna5 event logger from a batch job at startup time.
BUT this failed too.
	Subm/user=MCC_EVL  <------ Special account which I can play with.
				   At present I am screwing around with system
				   account.
				 (This node is DNS root server for the whole of
					British Aerospace)
Questions 
	Is there any log masks, I can set which will produce a useful log file?
	Is there any protection I need to check?
	What should the process quota be for the account starting dna5 event
	logger? 
	Do I need to modify any sysgen parameter.

I have run the MCC_AUDIT on the system account .Passed with flying colours

3556.1event rate?TOOK::PURRETTAThu Aug 13 1992 17:2310
    Gary,
    
    I'm going to try and reproduce the situation locally and see
    what's going on.
    
    Do you have any filtering at the outbound stream end?
    (PASS,BLOCK,IGNORE).  Can you give me some idea of the event
    rate on each of the streams?

3556.2trying to install filters on event streamsSEDSWS::MALLOYFri Aug 14 1992 08:3616
    John
    
    At present the event streams are open  (No blocks).
    We are trying to put filter on at present by the WANrouter
    are very flaky .
    Hopefully with good wind we should install some filter in the near
    future. I only HDLC LINK xxx Logical Station  xxxx station running
    					and station inoperative events. 
    
    	The WAnrouter seem to have a problem understanding Logical stream
    in the pass global filter command.
    
    
    I am on holiday for two weeks now .

3556.3Check SYSGEN parametersTOOK::PURRETTAFri Aug 14 1992 12:539
    Gary,
    
    when you get back, I would suggest looking at some SYSGEN parameters
    and see if they are high enough for the kind of I/O you're doing.
    
    I would look at PQL_DBIOLM and PQL_DBYLM

3556.4Ithought Pqlxxx wrer used by RUN/DETACHSEDSWS::MALLOYFri Aug 14 1992 14:4623
    John
    
    Today, I tried to start up the MCC collector,the same problem occured.
    
    DECmcc hang when trying to disable  the mcc_sink object.
    
    I enable MCC collector and the process was created but NO object.
    
    REboot machine both the DNA5 and Collector object were created.
    
    This may be a WAVE1 problem  
    
    I will check these parameter when I come back form hols
    
    
    John I thought that the DNA5 process took is quotas from the process
    that created it. Is ths correct  ????
    
    Run/detach , I thought used the PQLXXXX parameters

3556.5It _is_ a detatched processTOOK::PURRETTAFri Aug 14 1992 18:2724
    Gary,

    When you give the command

    MCC> Enable MCC 0 DNA5_AM Sink

    the DNA5 AM does a SYS$CREPRC with the PRC$M_DETACH flag set.
    So the EVL sink program is created as a detached process.
    That's why I suggested looking into those SYSGEN parameters.

    As for the problem of enabling and not seeing a process generated
    one thing I would do is a $SHOW SYSTEM and look for a process name
    called MCC_DNA5_EVL.  The program makes sure that it is the only one
    running by making sure there isn't any other process using the same
    name.  If you have run the EVL interactively, then it changed "your"
    interactive process name to this and the real MCC sink won't come up
    until it sees it's the only one on the system with that name.
    Unfortunately, this error doesn't get propogated back to the
    Director.  You could do an "Enable" and it would say it succeeded
    but what that means is that the CREPRC system call succeeded.
    Once the program is out there running on its own, it could bring
    itself down for the reason I explained above.

3556.6sysgen parameter requiredSEDSWS::MALLOYThu Sep 03 1992 08:267
    
    Here are the sysgen you rquired   
    
    			Pql_dbiolm = 18 default       
    			Pql_dbytlm = 8192 default
