ontape error

  • 1.  ontape error

    Posted 07/21/20 05:33 PM
    Hi,

    I am doing one RSS installation over version 14.10.FC3 and getting some strange errors.
    Using and old command that I used before:

    ontape -s -L 0 -t STDIO -F | (ssh informix@10.0.11.113 '. ~/.bashrc ; ontape –p -e –t STDIO ; onmode –d RSS cmsantar01_net')

    I am receiving syntax errors about ontape and onmode.
    There any new options to define? like DBREMOTECMD for bash?

    Thanks for any help,

    SP

    Sergio:

    Try using ifxclone instead, it handles all of the complexity of an archive-and-remote-restore for you, even setting the server type of the target when it is done. You run ifxclone on the target machine. It can optionally copy and modify the ONCONFIG and sqlhosts files for you or use ones that you have built by hand:

    $ ifxclone
    ERROR - missing required parameter (source (S))  
    ifxclone -SIPtip                          # Clone a server

    Oh, forgot, you also have to set ENABLE_SNAPSHOT_COPY to 1 in the source server's ONCONFIG file to enable ifxclone to work against that server.

    Hi Sergio,

    DBREMOTECMD is for TAPEDEV/LTAPEDEV remote syntax - not your case.

    What error are you getting?

    I think 'ontape --' syntax diagram is slightly misleading in suggesting -e and -encrypt might be synonym - they are not (-e is "external").
    Is it working with -encrypt instead of -e ?

     Andreas

    Hi Sergio,

    so you're not even intending to have the RSS encrypted?
    Then omit the -e altogether   --   -t <tape_dev>  and  -e (external restore) should be mutual exclusive, and what you're trying is not an external restore.

    As for that onmode syntax error, I'm clueless right now.

    Hi Sergio

    Your command syntax seems correct, so to me it implies it could be a Shell related issue. Split the work up into steps to see if it yields more information...

    [Pri]$  ontape -s -L 0 -F -t STDIO | ssh informix@<RSS IP or DNS name> "source ~informix/.bashrc; ontape -p -t STDIO"

    When your Primary returns to it's command prompt...

    [RSS]$  onmode -d RSS <Pri INFORMIXSERVER>

    ...or my preference is as @Art Kagel suggests, as it may be faster...

    Set these $ONCONFIG parameters...

    [Pri]$  onstat -g cfg | egrep "DISCOVER|SNAPSHOT|LOG_INDEX"
    LOG_INDEX_BUILDS 1
    ENABLE_SNAPSHOT_COPY 1
    CDR_AUTO_DISCOVER 1

    ...then...

    [RSS]$  ifxclone -T -S <Pri INFORMIXSERVER> -I <Pri IP or DNS name> -P <Pri Port> -t <RSS INFORMIXSERVER> -i <RSS IP or DNS name> -p <RSS Port> -d RSS

    ...then monitor the read/write activity with "onstat -D r 1" and also the Message Log. ​

    You will have to format your sqlhosts file and tidy up your $ONCONFIG afterwards because ifxclone doesn't like doing the housekeeping.

    Regardless of which method you choose, you may want to give consideration to RSS_FLOW_CONTROL on your Primary node.

    Hi Sergio

    The error that manifests from the ifxclone attempt is because informix has detected the existence of a previous Instance. I assume your target RSS node was down at the time and if it was you could try...

    [RSS]$  cat /dev/null > path-to-chunk-files/*

    ...and try again. I'm assuming you are using cooked chunks.

    As you can see from the ontape help; your syntax is fine. I'm guessing that your informix user .bashrc correctly sets up your RSS node environment and that the target Instance is down at the time you initiate the ontape on the Primary node.

    You can use the following command to clean up from a failed server startup or incomplete shutdown:

    onclean -ky

    Run it twice and all will be cleaned up.

    As part of the process then switch FULL_DISK_INET to zero, something like ..

     

    Sed –I "s/^FULL_DISK_INIT[[:space:]].*/FULL_DISK_INIT 0/"  ${INFORMIXDIR}/etc/onconfig.${ONCONFIG}

     

    or something like

     

    dd if=/dev/zero of=<ROOTDBS> bs=2048 count=100 –o notrunc

     

    If rootdbs is large then null'ing out the entire file can be expensive as it has to be built again from scratch

    Hi Paul 

    My reasoning for null'ing the dbspace chunk files is that in the past I have gone around in circles with FULL_DISK_INIT.

    I note your point however. Perhaps removing the root chunk file on the RSS node and then fallocate'ing to create it afresh might be an option.

    Had a customer with 200GB+ rootdbs, nulling and recreating took forever

     

    My standard restore scripts use the onstat –d to make sure all the files are in place and correct size before the actual ontape starts.

     

    But a mute point with raw devices

     

    Remember with encryption you will need to remove the keys as well if you don't see DISK_FULL_INIT. And if you are running multi-instance on a server then removing the wrong keys is somewhat annoying

     

    Cheers

    Sorry Sergio, I was away from the keyboard.

    I haven't read the entire thread so apologies if I type something that's already been discussed. Run this on the node implied in the command prompt...

    [RSS]$  onclean -ky
    [RSS]$  onclean -ky
    [RSS]$  ipcs

    If you still see any Shared Memory Segments it most likely means you could be running some other application that connects to informix and is still attached to the address in physical memory where informix wants to attach when it is initialised. In that case as the 'root' user run..

    [RSS]$  ipcrm -a

    This should blow everything away.

    Next...

    [Pri]$  onstat -g rss

    If you see your RSS noode from the first ifxclone attempt still defined, then run...

    [Pri]$ onmode -d delete RSS <RSS INFORMIXSERVER>

    Next...

    • Delete entry for RSS node from the sqlhosts file on your Primary node
    • Delete entry for Primary node from your sqlhosts file on your RSS node
    • Run your ifxclone steps again

    Good luck! I'll check this thread in the morning now (UK Time).

    Hi Sergio

    Any type of replication will require server/user level equivalence; it's not specifically an ifxclone requirement. Is using REMOTE_SERVER_CFG the policy in your organisation? If it is not, I would elect to use hosts.equiv as this has been a tried and trusted method for many a year now.
