534.0. "script loose scheduling entries??" by MUNICH::REIN (How come holes in SWISS CHEESE??) Mon Apr 28 1997 07:17

    Hallo,
    
    Customer Ruhrgas tells me, that every now and then all scriptfiles
    are loosing their scheduler queueing entries, so that none of the jobs
    is running.
    
    He has then to modify all entries!
    
    He is running DFO 2.2 with RMS database.
    
    regards
    
    Volker

534.1	Can I get some more information	COOKIE::AMEND		`Tue Apr 29 1997 09:38`	20
	Volker I have not experienced this problem so I do not have an answer. I am not sure how we go about troubleshooting this. Could I get the scheduler log (DFG$DATABASE:DFG$node_name.LOG) around the time the scipts loose their scheduler queueing entries? Could I get a full log defragmentation runs on disks that happened during the time the scheduler queueing goes away? Could I get the scripts that are loosing their scheduler queueing entries? I would like both the output of the SHOW and the SHOW/COMMAND. thanks for your support'a jim amend

	Hallo, I asked the customer about more info, and he will send it when the error comes up again. He delivered an entry from the logfile: Defragmentation process for script USER has completed Completion time was 15-APR-1997 16:13:19.75 %DFG-W-UNRECOVERR, unrecoverable error Target volume was DISK$HVCL_USER (_DSA1:) Improperly handled condition, bad stack or no handler specified.

534.3	Could we get some more information	COOKIE::AMEND		`Tue May 06 1997 14:39`	102
	Volker Thanks for the information. However, before we can go any further with this error, we would like some more information: Could you go into ANALYZE/SYSTEM and get the process images for the scheduler? The scheduler should be DFG$node_name: $ ANA/SYS sna> show summary sna> set process/index= sna> show process/images We need to know where the A06D4 address is. Also we would like a list of all of the system parameters. The unrecoverall error appears to have come when the scheduler went out the get virtual memory and could not get it. Also could you do a $ SHOW LOG DFG$* so we could see if any logicals for defragmentation process start up have been defined. Also, could you get the script for USER. One thing that we might try to clear up the problem is recreate the database. You can get the scripts out of the database into a command procedure, create a new database, inititalize it, and reload it with the following commands: $ DEFRAGMENT SHOW /ALL/COMMAND/OUT=DB_LOAD.COM Now you should go into DB_LOAD.COM and edit it. The commands that it created are longer than 256 characters. You can take out lines that are defaults like: /PRIOITY=(DEFAULT=4... If you have lines that are still to long, you can move the /SCRIPT line up and then change the other lines to DEFRAGMENT MODIFY commands like this: $ DEFRAGMENT VOL $1$DKA0:/NOAFTER/SCRIPT=USER $ DEFRAGMENT MODIFY USER/INTERVAL=1-00:00 This little exercise is changed in V2.3 so you will not have to edit it. After editing the file: $ RUN SYS$SYSTEM DFG$CREATE_DATABASE $ RUN SYS$SYSTEM DFG$INIT_DATABASE $ @DB_LOAD This might eliminate any problems that the database is causing. thanks for your supporta' jim amend <<< Note 534.2 by MUNICH::REIN "How come holes in SWISS CHEESE??" >>> -< more >- Hallo, I asked the customer about more info, and he will send it when the error comes up again.

534.5	Let me know if it happens again	COOKIE::AMEND		`Thu May 08 1997 08:47`	16
	Volker Thanks for the information. It appears that the engine did a lib$signal and could not get virtual memory and got the unrecoverable error. The scheduler tried to send mail and got an ACCIVO in the mail program. We are looking at the system parameters now to see if we see anything. Let me know if the problem happens again. If is does I would like the logs from the scheduler and defragmentation processes. thanks jim amend

534.7	Does not appear to be a problem	COOKIE::AMEND		`Mon May 19 1997 12:22`	20
	Volker In searching through the code for this error, I could only find one place that this error can occur. From what you say, it appears that a defragmentation process was running on the system when they shut the system down. If the disk was dismounted, while the defragmentor was running, the defragmenter could give this error. The error indicates that it went out to the UCB to find the VCB and the FCB and then walk to FCB to see which files were open. If the disk was dismounted then, the defragmentor could give this error. DFO does not stop any defragmentors on the system when doing a shutdown. Has the customer had an schedules that went away since recreating the database? thanks for your supporta' jim amend
