Rebooting the servers

DB version: 10.2.0.4.0
OS : Solaris 5.10
Lets say for a 2 node RAC, you want to restart both the machines.
After bringing down the CRS on both machines , Is it true that you shouldn't reboot both machines simultaneously?

I simply pull the power cable.. or hit the reset button... or press Ctrl-Alt-Del on the console.. or use the shutdown -r now command in a root shell. And that suffices in downing (and/or rebooting) the server.
And if that does not result in a clean and working restart of that server as part of the cluster, then your hardware is badly configured, your cluster architecture poorly chosen, or your s/w (o/s and rest) is incorrectly installed and configured.
It is a myth that one needs to shutdown RAC/CRS services in a neat little sequence. If you cannot pull the power cord and get a successful reboot and working server when you plug that cable back, then you do not have a "real and working" cluster. You have something far less and inferior - you have a waste of money that you should not be calling Oracle RAC.

  • May I deploy MS patches on windows servers, and reboot the servers later?

    Hello,
    I am trying to steam line patching process. May I deploy MS patches on the windows servers first and then reboot the servers at a later time? say days later.

    For CCM, that is a big no. You need to get the updates that have been approved by Cisco from Cisco. They are available at the following link. Read the release notes very carefully! There are very strict upgrade sequences. I suggest that you consider upgrading to UCM 6 or 7; the updating process is much easier.
    Cisco Unified CallManager Version 4.1 > Voice Application OS and BIOS Updates
    For Unity, you can typically download and run the Update Wizard which will have the approved updates rolled in. Depending on how immediate you want to be about it, there is also a support policy for Windows Update

  • SAP Portal changes not reflect in all the  servers without  reboot?

    Dear  SDN Members
    We have  one sap ep 7.0 eh1  main instance   and  4 other portal instances.every time  we tranport any  portal develpment work  such as epa packages, we need to restart all the instances to reflect the new changes.can you please suggest me
    a solution if  exists to avoid  bouncing of all instances when a portal development work is  transported.
    Why does the changes not reflect in all the servers without the reboot??
    Thanks
    Chandra

    Thanks for the quick response kenny, i wonder if we can configure any parameters in UME
    to avoid bouncing of all the instances. please let me know if you have any other suggestions.
    actually we have  a central portal instance and 4 other  portal servers connected  through a
    load balancer.Any tranport we move to central instance should refelect the changes in all
    other portal instances.But we need to restart all the instances to see the new changes.
    We are trying to find a solution if availbel which prevents server-restarts after each transport.
    Thanks

  • OVM Manager 3.1.1 can't discover one of the servers

    Hi,
    I have a weird problem with one of our OVM3 servers. Due to "System is initializing ..." errors I had to delete and recreate the OVM Manager DB. The operation went smoothly but after a restart I'm only able to discover one of the servers (soaovm2). We actually have each of the servers in a separate pool (self-tough best practice if you plan to use RAC on the VMs). So, as mentioned the second server was discovered just fine (with pool and everything) but the first server is refusing to get discovered:

    I would appreciate any ideas here (preferably ones which wouldn't require rebooting guest VMs ...) as I have no clue what to try next.

    I ran into this issue.  The fix for me was to restart the ovm manager (so on the ovm manager I ran "/etc/init.d/ovmm restart") and then I restarted the ovs-agent on the host. So I did "/etc/init.d/ovs-agent restart".
    If you need to you can reset the ovs agent password from the host by issuing "ovs-agent-passwd oracle <password>".
    Hope this helps.

  • Revenue recognition job hangs and needs reboot of servers

    We are on SAP BPC v7.0 SP6.1, using Microsoft Office 2007 and Internet Explorer 7.  We have two environments - Production and QA.  Production so far is running fine; QA is on a smaller environment. 
    I am an application user and load final production files into QA each month.  For the past two months when trying to run the revenue recognition job for April 2010 and again for May 2010, the job just hangs where it would normally take about two minutes to complete.  Both times it was the only job running at the time, as no one was using the QA environment.  I had to terminate the job (which might leave the job running in the background) and have our Server team reboot our two servers (Application and SQL Server Analysis Services).  Then the revenue recognition job completes.
    Depending if I terminate and resubmit the revenue recognition job, I might get the following detail log message:
    Execute formulasError
    Failed to commit transaction
    1 errors writing data
    Send through SendGovenor failed
    Last week, our DBA set the QA databases to Simple instead of Full recovery and shrank the transaction log files.  I ran a test revenue recognition for July 2010 and the DBA tried to monitor the environment, but he could not see any job committing or any activity on the database.  I ended up rebooting our servers to complete the test.
    Has anyone experience similar problems and was able to resolve it.  Any ideas would be appreciated.  Thanks.
    Bucky

    Hi Sorin Radulescu,
    I load the initial billing file using the Import logic script and select the data file and transformation file.  I click on the Merge data values option; click No to run default logic; and click No, do not check work status settings.  Once the import completes, I run the revenue recognition logic for the accounts and periods I am working with.
    I compared our Production transformation file, default logic script (which I am not running), and revenue recognition logic script to QA and they both match.  My problem is when I run the exact same revenue recognition job in QA, the job just sits in running status but should finish in a couple of minutes.  I would let it run for a couple of hours in QA, then terminate the job and have our two servers rebooted, then the same revenue recognition job runs to completion within a couple of minutes.
    I am just wondering if there could be some other setting that does not let the job submission kick off the actual update to the database.  To make sure the database was not hosed from the terminated revenue recognition job, I ran a different but smaller job and it completed.  Then I would ask for the reboot and resubmit the revenue recognition job and it completes.
    I will let our DBA know about monitoring the dllhost.exe for amount of memory used.  But the last time he tried to check for any activity on the database he could not see anything, but I do not know if he was checking dllhost.exe or some other files.
    Thanks for your response and suggestions.  Since this is our QA environment (which I try to keep current with Production), I am trying to see if I can identify the cause and fix it, in case it carryover to our Production environment.
    Regards,
    Bucky

  • Cat3750 stack, sw-upgrade without rebooting the whole stack at the same tim

    hi,
    i've gout a question regarding catalyst 3750 stack software upgrades.
    is there any possibility to do a software upgrade to the stack without rebooting all stack
    members at the same time?
    i tried to do this manually with "archive download-sw /overwrite"
    (without using /force-reload or /reload parameters) and then reboot one of the two members
    in the stack. the remaining switch correctly becomes the Master. But when the member with the
    new software comes up again, a version missmatch is detected (by the switch running the old sowftware) and the upcomming switch stucks in the boot process.
    so everything i tried, i've got a network down for the whole stack.
    we have a scenario where servers are connected to both members of a stack (for REDUNDANCY and
    bandwidth aggregation). it would be nice if' there's any procedure to do an upgrade in the stack without
    losing both connections to our servers at the same time...
    kind regards

    hi clare,
    thanks for your reply. i tried your described procedure, but with no success.
    rebooting both switches, regardless which software the have in their flash, will interrupt the connected servers, because both links (to the stack) are going down at the same time (to achieve this, its easier to use the standard procedure as described in the config guide).
    the idea with a seperated sw-download with different feature-set's sounded interesting for me in the first moment.
    unfortunately it doesn't work too. after the sepedated download to the switches as soon as i reboot one the switches to load the new software, the other becomes (or stays) master of the stack. once the rebooted switch with the new software comes up again, the mastes displays a version mismatch (and the upcoming switch stucks in operation, awaiting the pretended correct software).
    at this stage i can only reboot the master switch which results in complete outage of the stack (the upcoming stucking switch reboots too).
    i have posted the question in the "ask the expert, high availability.." threat too, so maybe the expert has an idea to accompish this task ;-)
    kind regards

  • AirPort Extreme extends my network and has worked well for three months. Now it can no longer extend the network and flashes Amber. I have restored to factory settings moved it closer to time capsule and rebooted the system without luck

    i have a blinking Amber on my extreme now and it cannot extend the network.  It was working fine and nothing has changed. I have restored to factory settings moved it to another room and rebooted the system without luck. Any suggestions

    What OS are you running?
    Please give me a screenshot of the current AE setup..
    I strongly recommend if you have issues.. take control of all the variables. Apple routers have too much auto..
    Here is a list that I use for setups when using Yosemite.. but it relates to any OS.
    You will need to factory reset again to get going.
    Factory reset universal
    Power off the AE.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the AE to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
    Then redo the setup from the computer with Yosemite or whatever you are using.
    1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
    eg AEgen5 for basestation.
    Use AE24ghz and AE5ghz for wireless on each band, with fixed channels as this also seems to help stop the nonsense.
    2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
    3. Ensure the AE always takes the same IP address.. this is not a problem for router but if the AE is bridged you can have trouble.. Try using the static IP method or control it via the main router dhcp reservations.
    4. Check your share name on the computer/s is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric..
    5. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
    6. Set up the extend to the Express using 2.4ghz and then see how good or bad the connection is.. this is better in the old v5 utility but if you hover your mouse over where it shows connection an extra chunk of info comes up.
    I have specifically used 5ghz to make the extend.. because by testing it works better.. but do not be fooled.. this good connection is poor.. the RSSI.. which is difference signal .. at -79dbm is down the bottom of the stable.. and it drops out on a daily basis.. you want to see that signal around -60dbm at min.
    There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.

    - Connect the iPod to the computer and see if iTunes sees it. If it sees it try to get the photos off the iPod.
    - Next let the battery fully drain. It will likely take days. After charging for at least an hour try again
    - Last, make an appointment at the Genius Bar of an Apple store.

    I have a problem with Mail on my Macbook Pro. It is configurated with a gmail account, and now I can't access the mail. Is it possible to reboot the account or..? Please help:)

    The question mark means the computer cannot find a bootable volumes so can;t do anything, That, combined with annoying sounds, strongly suggests a failed hard drive.
    You can ask a "genius" at an Apple Rtail Store to test it but I'm pretty sure the drive is kaput. I'm hoping you had your data backed up.

  • My apps have been crashing since last night on iPhone 4g anyone having this problem.  it only started last night i have rebooted the phone and some times cannot even download my email nor move them to trash where they re appear a few minutes in inbox

    my apps have been crashing since last night including even the app store.  this only started happening late last night since doing the ios 5.0.1 update.  i am not sure what is happening.  even when i click on the phone buttom the apps are all crashing not loading stuff.  i cannot even seem to get email only some of the time and than when it does and i try moving them to trash they dont go to trash they re appear right back in my inbox a few minutes later.  i have rebooted the iphoine a few times but with little avail to any situations that are working for me currently.
    i think this is an apple ios 5.0.1 update issue.  i think they may have screwed things up big time this time.  i have also found no improvement with battery life at all.  not sure what is wrong but i hope they fix it fast.  this is ridiculous
    please respond if you are having some of the same issues as i am
