2718.0. "OAFC$SERVER and quota problem" by CROCKE::YUEN (Banquo Yuen, Darwin Australia) Mon May 17 1993 10:53

    After upgrade from V2.4 to V3.0, the OAFC$SERVER went on perfectly for
    three weeks, then suddenly it got an "insufficient memory" error which
    was also logged in SYS$MANAGER:OAFC$SERVER.LOG, I define the system
    logical OAFC$SERVER_PGFLQUOTA to 100000 because this error occurred
    when the page file count reached 60000 which is the default found in
    SYS$STARTUP:OAFC$STARTUP.COM.  At the same time I found that the
    customer has around 100 shared-drawer but the default maximum drawer
    for the server is only 50, so I changed that to 100.
    
    After that the server goes wrong in the rush hour everyday.  Everytime 
    when it goes wrong, the page count is around 40000.  The error message
    may be "RMS error ...", "%OAFC-I-DSTNF A target was specified that does 
    not exist", "Server not available ... " etc...
    
    I have tried to increase the BIOLM and DIOLM but didn't help.  I have
    looked at the other quota, they are quite sufficient when the server
    goes into this state of delirium, keeps mummmm crazy error messages.  The
    error messages are not logged in the SYS$MANAGER log files.
    
    I don't know how to check whether the BIOLM and DIOLM have been exceeded or
    not.  Other quota I can check by showing the process.  Moreover I don't
    know how this will happen because the process has EXQUOTA privilege.
    Furthermore I don't know whether the PQL in SYSGEN will have any effect
    or not.
    
    The ALL-IN-1 system is running on a cluster of 2 nodes.  The other less
    powerful node thus less users runs perfectly, no error reported even
    when the other node goes wrong, ie. also why I think it may be a quota
    problem.
    
    To regain the soberity of the problem server, I have to stop and start
    the server.
    
    And what is the effect of stopping and starting the server when a lot
    of users have already attached to the server?
    
    Thanks
    Banquo

2718.1	Max links/Channelcnt	JGODCL::SHERLOCK	L.U.F.C. The phoenix has risen	`Mon May 17 1993 11:32`	10
	Banquo, You should try checking the EXECUTOR in NCP for the Maximum links value, also check the SYSGEN parameter CHANNELCNT. We had similar problems to yours during peak periods and after increasing these values the problem was solved. As far as stopping the File Cabinet Server, this shouldn't cause any problems as the server will allow any clients that are connected to the server to complete their operations.

	Re - 1 Banquo, as a P.S. on a 4 node cluster with 750 ALL-IN-1 users, each node has the following parameters: SYSGEN parameter CHANNELCNT - current value 1024 NCP Executor maximum links 255 HTH Tim
2718.3	Could be quotas - but 40k pages is a lot.	IOSG::CHINNICK	gone walkabout	`Mon May 17 1993 15:45`	16
	It may be that the FCS is leaking some memory although it sounds like you are hitting the limit pretty fast. I'm not sure if a patched version was produced for a problem like this - not really my department - but it is worth checking. If you are pushing PGFLQUOTA - you also may need to up the SYSGEN parameter VIRTUALPAGECNT which is the maximum virtual size of a process. You might also run very short on pagefile space if you aren't careful so I'd suggest increasing the pagefile size too. EXQUOTA privilege will only help for disk-quota and not VMS process quotas. Paul.
2718.4	secondary server 128	CROCKE::YUEN	Banquo Yuen, Darwin Australia	`Tue May 18 1993 10:26`	19
	I have checked the NCP max link and max alias link (even thought I don't think it will use the cluster alias), I have checked the VIRTUALPAGECNT, page file size but not CCANNELCNT, so I will check this tomorrow when I am there. While waiting for your reply, I created another server on the node today with object number 128, but it would not work, it just sits there and saying running/enable even the server 73 is on a heavy load. Moreover, this server 128 would not work even I stopped server 73. So how can I make a secondary server work? I have checked the partition field in the partition.dat, they are all blanks, shall I cheange it to something like 0::"128" or anything like that or even to 0:: or whatever (but I guess this only specify the location of the partition.dat) Thanks Banquo
2718.5	How load balancing is achieved.	IOSG::STANDAGE		`Tue May 18 1993 11:25`	18
	Banquo, Sorry, this will have to be brief - and is actually something I'm doing at this very minute! ALL-IN-1 will always use DECnet object 73 unless you have DNS naming enabled (i.e. the server is running Distribution level 1). However, you can force selected clients to use a different server object by defining OAFC$SRV_OBJ in their LOGIN.COM. Brokering to remote systems will always cause a connection to a remote object 73 server, unless you also have OAFC$BROKER_OBJ defined. Kevin.
2718.6	Otherwise it'll never work!	IOSG::STANDAGE		`Tue May 18 1993 11:34`	11
	Finally, when defining OAFC$SRV_OBJ make sure it is the object number ONLY - and nothing else ! e.g. DEFINE OAFC$SRV_OBJ 177 Kevin.
2718.7	don't use OAFC$BROKER_OBJ	CHRLIE::HUSTON		`Mon May 24 1993 16:17`	14

I would not recommend having a customer site use OAFC$BROKER_OBJ, it is not supported. OAFC$SRV_OBJ is supported so feel free to use that. --Bob
2718.8	That's true	IOSG::STANDAGE		`Mon May 24 1993 16:25`	4
	Ooops...forgot that! :-) k.
2718.9	probably the channelcnt	CROCKE::YUEN	Banquo Yuen, Darwin Australia	`Wed May 26 1993 11:39`	13
	Hello The sysgen channelcnt is only 300, so this is probably the reason why the server is not working properly, but the customer don't want to schedule a reboot, so I have created another server and use the OAFC$SVR_OBJ to distribute user groups to use different server, the customer is happy for the moment. And I discovered the channel count and number of channel connected are actually shown on sai screen rather than the sri screen. Thanks Banquo
