What would happen if application server needs to be restarted?

I am talking about a scenario where application server hangs and needs to be restarted, because you couldnt do anything on it. What would happen to any insert, update of data taking place at that time. I guess it will all be rolled back if they are not committed and written on the data files. What would you do in this case before restarting , what would you check after restart of the system? Please share your experiences.

Hi,
>What would you do in this case before restarting , what would you check after restart of the system? Please share your experiences
SAP has its recovery manager([click|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a8910c3a-0d01-0010-a6a9-f4a8aae140fe] BR Tools) and every time you restart the server the system will be rolled back to the last safe point if there were any undone or not commited queries.

    One is for the base version of the Mac OS, the other is for the Server version. You can only install the one that matches your system.

    Hello Guys, what would happen if I reset my iPhone5 - reset all settings

    If you select the option to reset settings, all settings will be back to default ones, but you will not lose any application, song, movie, etc.
    If you select the option to reset all content and settings, your device will be wiped and it will be back to default settings, so you will need to set it up and transfer all your content to your phone

  • After transaction completed in undo tablespace what would happen? will they

    after transaction completed in undo tablespace what would happen?
    will they take out of undo tablespace or segment?
    please elaborate, thank you

    Hi,
    Even, if the transaction is committed, there may remains a need to retain the undo data. For instance, for the long running queries or for the flashback features. In automatic undo management, you may specify the undo retention period, which is the minimum amount of time that Oracle Database attempts to retain old undo information before overwriting it.
    One may also enable the retention guarantee, which ensures that the undo data will remain in the undo tablespace, even if that means that the transaction would fail due to lack of space in the undo tablespace.
    In addition, also read the following:

  • Mailbox has "archive" with thousands of emails in it, probably every email I've sent. What would happen if I deleted them?

    My Mail has a mailbox labelled "Archive."  There are literally thousands of email
    in it, probably a copy of every email for many years.  What would happen if I
    deleted these?

    If it is a Gmail account, that is normal. How do you expect Google to exploit your privacy if they let you just delete your emails willy nilly?
    GGmail isn't a normal IMAP server. It's not really an IMAP server at all; it just pretends to be one.
    Instead of organizing messages into folders, it tags messages with "Labels." A message can have multiple Labels. By default, a new message comes with an "Inbox" Label and an "All Mail" Label. When you "delete" an email from GMail, it merely removes the "Inbox" label, but keeps the "All Mail" label.
    When Apple revamped Mail, it made it more capable of working with GMail. One of those things was to map the "All Mail" label to the Archive folder in Mail. Now you can see how Google has kept all of the email you thought you were deleting.
    Take a look at this article and the follow up article it links to: http://jeffschuette.com/2012/03/07/setting-up-apple-mail-to-rock-and-roll-with-g mail/
    I used it to set up Mail and GMail so that when I delete an email in Mail, it also deletes it from the GMail server.
    Most ost of the firat article is no longer needed, except the step to force deletion of emails.

  • Leopard for G4 867mhz or above. What would happen on G4-400mhz?

    what would happen installing Leopard on less than a G4-867mhz?
    Would it work but be too slow for apple to be confortable supporting?
    Or do those machine lack hardware support?

    I'm not really a fan of old OS's, programs, or cobbled machines that I've built. They did the job, but I kept saving my money for better results.
    Most of the G4's, expecially the iMac's can not be upgraded with anything but ram. Your done. Some people are trying to get Leopard to run on 400 mhz G4 iMacs with their included video cards and chips on the motherboards. Now if you're talking about a tower like my Dual G4 1.42 Ghz then you're right, I've already added all of the hardware I wanted, including the ram, video, USB2, bluetooth and gigabit ethernet. But I started with a very capable machine that was worth upgrading. The limit here is the speed of the motherboard bus, and the slower G4's should be just put out as a Tiger game machines and save your upgrade money for a new iMac. I've moved the old machine into a back office to run Leopard server, and got the wind tunnel out of my workspace. When the ATI 9800 pro video card bit the dust because of a fan failure, I just put the original card back in and don't need the high end video on a headless server.
    The upgrades I did were to keep my production machine up to speed for a couple of extra years, but those years are long past, and my MBP and iMac's run rings around it for less money. Every Mac I ever bought before the Intel Mac's cost $3000 plus upgrades. These new $1100 to $1400 machines blow them away. I played with drop-in CPU's from Newer Technology in the past (they only cost 3 or 4 hundred), and they worked for a short time, but invariably I needed to run special patches from the vendor to be able to even install the later OS's.
    I'm not sure what you mean when you say you didn't touch the hardware at all. It seems like you changed everything that wasn't soldered to the motherboard (except the CPU and maybe ethernet). It sounds like you've been able to buy your way up to it's present level, piecemeal. OK. The fact that you got an older machine to run faster than it did has nothing to do with how fast or reliable a machine made in the last 3 or 4 years will run, natively, supported by Apple with all updates and drivers, video improvements, built-in camera's, etc. All of the improvements you made, and much more are already available with much higher performance on the new iMac's. There are so many people who believe that Leopard will speed up their computers just by installing the OS. They should have just stayed with Tiger and got Leopard with their new machine, just like the millions of Vista users who expected speed for nothing.
    WinXP will run on an early slow 486 processor. You'll save a lot of money if you do it. What's the point? I don't buy computers based on how little I have to spend to get work done (that's the PC mentality that drives me nuts as I wait for the machine and the hour glass to get back to me). I buy them based on how much work I can get done. When a program's developers decide not to upgrade or patch their program for the new OS or architecture I bid them a fond farewell and move to a company who makes products that perform well with my new machines. These machines and existing programs do not improve with age and developers who want to sit on their laurels and reap income from old work just seem to fade away. Adobe and MS are doing their best to write better code, as are thousands of independent programmers.
    It's time for Snow Leopard to re-establish MacOS as a performance OS Leopard is only marginally better than Tiger even on Intel CPU's due to being dumbed down and bloated with legacy code. Losing the PPC processor and compatibility code will improve MacOS measurably.
    Programs that won't run on SL, and machines that can't run it need to go away (make it into a fax server or contact management work station or something useful). As long as I can get to the machine on the network, it has value, just not for production.
    Sorry, just wrote another chapter

  • I just backed up my mac to an external hard drive using Time Machine. What would happen if I turn Time Machine off and then plug the external hard drive back into my computer?

    I just backed up my mac to an external hard drive using Time Machine. What would happen if I turn Time Machine off and then plug the external hard drive back into my computer?
    What I am ultimately wanting to do is make more room on my computer by backing up all of my files onto the external hard drive and then deleting them off of my computer. However, neededing to be able to retrieve them from the external hard drive later down the road.
    From what I have read and am trying to understand, is that I probably shouldn't have used time machine. I need to use the external hard drive like a basic flash drive where I can put things on and get things off without having it automatically update through time machine everytime I connect it to my computer.
    Not tech savvy at all and barely understand basics. I need very simple and easy to understand explanations.

    BIG BIG MISTAKE ..... youre making a linchpin deathtrap for your data trying to shove everything on a single fragile HD.
    Dont suffer the tragedy other people make, buy another or 2 more HD, theyre cheap as dust.
    The number of people who have experienced terror by having a single external HD backup is enormous.  One failure that WILL HAPPEN, and kaput,......all gone!
    Dont do it, its all about redundancy, redundancy, redundancy.
    follow here:
    Methodology to protect your data. Backups vs. Archives. Long-term data protection
    Deleting them off your computer is fine....having only ONE copy is extremely BAD.
    The Tragedy that will be, the tragedy that never should be
    Always presume correctly that your data is priceless and takes a very long time to create and often is irreplaceable. Always presume accurately that hard drives are extremely cheap, and you have no excuse not to have multiple redundant copies of your data copied on hard drives and squirreled away several places, lockboxes, safes, fireboxes, offsite and otherwise.
    Hard drives aren't prone to failure…hard drives are guaranteed to fail (the very same is true of SSD). Hard drives dont die when aged, hard drives die at any age, and peak in death when young and slowly increase in risk as they age.
    Never practice at any time for any reason the false premise and unreal sense of security in thinking your data is safe on any single external hard drive. This is never the case and has proven to be the single most common horrible tragedy of data loss that exists.
    Many 100s of millions of hours of lost work and data are lost each year due to this single common false security. This is an unnatural disaster that can avoid by making all data redundant and then redundant again. If you let a $60 additional redundant hard drive and 3 hours of copying stand between you and years of work, then you've made a fundamental mistake countless 1000s of people each year have come to regret.

  • What would happen if I were to delete the primary email address linked to my Apple ID?

    I wish to completely de-activate my @hotmail email address in order to be left with just my @icloud email address becuase I would find life more managable that way.
    I found out that I cannot change my primary @hotmail email address linked to my Apple ID with an @icloud email address as it is an active, separate Apple ID (in itself with a separate purchase / download history etc)...
    Also I am aware that separate Apple ID's cannot be merged together...
    My question is: "What would happen if I were to delete the primary email address linked to my Apple ID?"
    Would I be able to keep and use my purchases, provided they are backed up on my Mac and authorised?
    Would I be able to update those transferred purchases even though the email address linked to the apple ID in which the app was bought no longer exists?

    You can change the primary e-mail address associated with your Apple ID, so long as it isn't a mac, me or icloud email.
    http://support.apple.com/kb/HT5621
    Your Apple ID account, regardless of the primary email, can never be 'deleted', just abandoned.
    You could always just switch between the two Apple IDs as needed, to access the different purchases.

  • What would happen if I used Recovery Disk?

    I've recently bought a new iMac (Core i5) that came with Lion pre-installed, but I needed Snow Leopard for all my older software e.g. Photoshop CS, so I got the sellers to install SL for me. Everything is fine.
    Out of curiosity I tried to see if I could run Tiger from my old G5 HDD which is connected via USB, but it didn't come up in the list when I did Restart + Option. However, what DID come up was an extra drive named "Recovery". I understand this is a separate Lion partition on my HDD - so, what would happen if I selected that via Restart + Option? Would it open Lion on my iMac so I could have a play around with it? And if it did, would I then be able to get back to SL and all my data, users, and settings, after I'd finished?
    I don't want to try it out without advice, in case Lion overwrites SL irretrievably.

    christopher rugby wrote:
    My question is this : can I safely restart from Recovery in order to just play around with Lion, or will starting from Recovery reinstall Lion over the top of SL on my main disk?
    If your machine only has SL and the Recovery HD, then the only thing you can do when booting into the latter is REINSTALL Lion on top of SL or do some basic things, but Lion isn't installed. Details in Recovery/ and About Lion Recovery.

  • What would happen if site to site conference call using G.729

    conference bridge I am currently using is software conference , I am aware that Cisco software conference bridge only support G.711. and my project is a multisite project and site to site calls are via wan not PSTN. so my question is what would happen if a site to site add hoc or meet me conference call is made based on G.729. it doesnt work at all or there are some alternatives. I appreciate any input, thank you in advance

    The main problem is that you will need some xcodes or MTPs in order to use the Software conf bridge, but be aware that using G.711 conf through a WAN link will decrease the available bandwidth and it might fail, for instance, G.711 uses 80 kbps, rather than G.729 that uses 24 (3 G7.29 calls per 1 G.711).
    Here is the codecs' bandwidth utilization:
    - G.711 call uses 80 kbps
    - G.723 call uses 24 kbps
    - G.729 call uses 24 kbps
    - GSM call uses 29 kbps
    - Wideband call uses 272 kbps
    At this point the only option that you have is to get an HDV module and some DSPs and configure a HW xcode and conf bridge.

  • What would happen if function is declared as autonomous_transaction

    Hi all,
    Can any one tell me what would happen if function is declared as autonomous_transaction ?
    Will it affect other DML's in the current session .Please help me.
    Thanks in advance
    Regards,
    P Prakash

    In (another) addition, I recall getting deadlock errors as well, due to a totally wrongly defined transaction, using slow-by-slow processing (many moons ago, but I still wake up screaming in the middle of the night when dreaming of that code).
    Will it affect other DML's in the current session .Please help me.It depends on in what way you're applying autonomous transactions. From that point of view you gave us little information sofar.
    It depends on the understanding you have of them, regarding how they work, and what surprises/data corruption/errors they can give you.
    We don't know what you're trying to implement here, but I'd stay far from using an autonomous transaction.
    They're only good for logging errors.
    Not for fixing datamodel issues or fixing poorly designed transactions based on incomplete/incorrect business rules.
    They are not workarounds.
    That's been my rule as well for years now.
    In general you need to stay away from them. Far far away. Just like the WHEN OTHERS exception.
    And especially when you've come to believe that an autonomous transaction will save your day, while it's doing something else than errorlogging in a separate procedure call which in it's turn an autonomous transaction!
    Suggest you read up on DML Error Logging then.
    You can search http://asktom.oracle.com for more examples and explanations.

    If you have multiple devices backing up to the Cloud, you will see all of them listed. You would click on each device to change what is backed up from that device. You can then delete your individual back-ups.
    Once you have all your settings to your liking, you can then go back to Settings>iCloud>Storage & Backup, and click on Back Up Now (bottom of the screen) to create a fresh backup with your new settings.

  • What would happen if I forgot to click on eject, before disconnecting ipod?

    Is it neccessary to click on the eject button before disconnecting my ipod? What would happen if I forgot? Would I lose all my music?

    Ejecting is so old school. I just unplug it like I have been doing for years. No problems yet. I figure that the hardware shouldn't be affected even if there is a little data loss and if it is, it's crap and I will take it back.
    I think the ejecting legend has become a remnant from old-school mac days that hangs around to keep you from unplugging while syncing. Shouldn't be a problem....at least from what I have experienced on Windows. I am not sure if Macs still require that ejecting stuff on external media...
