Switching off unused J2EE services

Hi there!
I have a question regarding J2EE services. We all know SAP J2EE WAS is a very rich implementation but... Suppose you don't need a bunch of those services, and you would like to maximize your box performance. Beside "common" way of tuning, could switching off unused services be an option? (e.g. I don't use web dynpro, so why keepin' it up?)
Technically speaking, how difficult is it in your opinion? Specifally in finding services' dependencies?
Politically speaking, and contract and license wise, is it feasible? Will SAP still support me on services that are still swtiched on? (Given that they don't malfunction because of one the service I have switched off, of course...)
I am referring to a NW CE instance, particularly.
Thanks for sharing your opinion.
Cheers,
Alex

Hi Alex,
For 7.0, there is the note https://service.sap.com/sap/support/notes/871394 - but it seems there is no note for 7.1.
Even the 7.0-note is old and has entries not existing any more and does not cover all services existing meanwhile; some entries are also not helpful and leading into the wrong direction, so one should read the Excel-File very carefully and should know what one is doing if turning off services...
The bad news is that (solely) turning off the (superfluous) services, at least if you have a portal running (on 7.0), this does not decrease the startup time very much. I'm just digging deeper for more ways to optimize this, and also hoped shutting down the services would help efficiently, but... :-|
Best regards
Detlev

  • My 9220 restarts and switch off itself and service center can't fix it.

    I'm in need of help. My BB frequently turns off by itself, even if there are no applications running. I tried to restart it by pressing the power button, but that never worked. I had to hard restart it by taking off the battery and then putting it back on again. I need to do this around 2 or 3 times (only once if i'm lucky) to get it to turn back on. The frustrating part is when it shuts itself down again only a couple minutes after I had managed to turn it on again.
    I took it to service center and there they collected it but since last 1.5 Months i am trying to get my phone but they say that we didn't fixed it.
    Please help me.

    Without the device in your hands, it's rather useless to have advice since you cannot carry it out. But, since you desire it, here are some things you can try. I do not know which, if any, will work for your situation.
    I recommend that you attempt to boot into Safe Mode:
    KB17877 How to start a BlackBerry smartphone in Safe Mode
    It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.
    If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.
    But if the behavior continues in Safe Mode, then you may need to consider more drastic actions -- WIPE, OS Reload, BBSAK Wipe/Reload, and the "Bare Bones" OS Reload Process. To prepare, you should be sure that you have a full backup to your PC...please review the Backup link in my auto-sig on this post for instructions.
    You may also need the use of these tricks:
    KB10144 How to force the detection of the BlackBerry smartphone using Application Loader
    KB27956 How to recover a BlackBerry smartphone from any state
    http://crackberry.com/blackberry-101-lecture-12-how-reload-operating-system-nuked-blackberry
    On the chance that your battery may be causal, please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
    With the battery inside, connect your BB to the wall charger
    Leave it alone for 2 hours, no matter what the LED or the display does
    Remove the battery
    Wait 15 minutes
    Insert the battery
    Wait another 2 hours, no matter what the LED or the display does
    This has been known to "kick start" some BBs.
    It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
    Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
    Obtain access to a known good and identical BB...use your battery in it and see what happens
    The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
    Good luck and let us know!

  • How to switch off ni web services

    I enabled the NIweb services by checking "Enable Web Server" in Tools/Options/Web Server: Configuration. As I do not need this functionality I disabled the feature, but still my compiled applications create a "niwebserver.conf" file causing a runtime error. How can I disable the Web Services function?
    Andreas L

    Hi Andreas,
    Exit LabVIEW. Rename your labview.ini file to something (to back it up). Ensure that there is no labview.ini file beside labview.exe. Now launch LabVIEW. If you are still getting an error, the error is not due to web services. We'll require more information to solve the problem. 
    If the problem persist, please try repairing the LabVIEW installation.

  • Is there a way in which you can deliver messages only through iMessages and not text messages .  If the other iphone user has switched off the data services then the message gets delivered when the user switches on the data services.

    I want messages to be delivered to the other person only through iMessages . Is there a way to disable text messages being sent to the other iphone .

    In message settings, disable the send as SMS setting. That does mean any message sent to a non-iMessage enabled device will just not get sent.

  • Switching off location services disables cell service?

    Is this right? If I switch off location services, I cannot send or receive cell phone calls. Basically switching off location services is the equivalent of putting my phone in airplane mode?
    I'm using an iPhone 5 with the current iOS.
    Thanks.

    No, it's not right. Turning off location services should not be the same thing as putting the device in Airplane mode. Airplane mode turns off all of the radios (wifi, cellular, BT and GPS). Turning off location services doesn't disable cellular or, rather, it shouldn't in a properly working phone. I'd start with the standard troubleshooting steps.
    Best of luck.

  • Iphone 5 "No service" when cellular data is switched off

    Hi I've had my iphone 5 for about 3 weeks now.
    I used to switch off cellular data on my iphone 4 because I'm always near
    wifi at home or at work, because I don't want any nasty bills at the end of the month.
    I switched cellular data off on my iphone 5 and noticed that I lose network service, and when cellular data is re-enabled I get service again!
    I thought it was maybe just a bug so I Restored.
    But same issue, then I waited for newer firmware hoping the issue would be fixed and updated to 6.1
    but the issue has still not disappeared.
    I then decided to ask another iphone 5 user to switch their cellular data off to see if it did the same thing.... It also lost network!!!
    I am on Telecom and the other user on Vodafone. (Newzealand)
    I don't have this issue with my old iphone 4, so what's going on?
    Does any one else have this issue?

    No, it's not a common issue with the iPhone 5.
    Replace the SIM. 
    Reboot the router.
    Confirm the router is running the latest version of firmware available.
    If the problem continues, take the device to Apple for evaluation and possible replacement.

    Call your carrier and see if there is an outage in your area... Try re-setting the phone. Go to another location and see if the problem persists. Pay your phone bill. These are all possibilities. Without more information, we're just guessing.

  • My Iphone as been switched off how do i service it this phone is brought in Singapore???

    I Brought my IPhone through my friend in Singapore a year half back now my phone is switched off there are lot of battery life left how do i service this phone when i called service center in Bangalore they mentioned i will have to get in touch with Apple direct.

    You purchase an airline ticket and get a hotel room and you fly to Singaport and take it to an Apple repair site. I'd suggest you make an appointment before you go. Or you send it to a friend or relative and have them take it in for service.
    Apple will not accept shipped iPhones from another country for service.

    Hey jayashri,
    I'd give restoring a shot, but I'd make sure to back up your content first. You can read about how to do both things in the following article:

  • BlackBerry Z10: Default Battery Percentage Level for individual services to switch off

    We all know BlackBerry switches off services one by one when the battery reaches critical level. But is there any fixed battery level to cut down individual services. For example, Bluetooth will be switched off at 20%, Mobile data at 15%, Wifi at 10%, etc. I am searching these in BlackBerry documentation and Googling as well. But I am not able to find such info. Any help please.

  • I have Find my Phone enabled. Could a thief switch off location services to stop it being tracked? If so, an update must place the location services and icloud into the restrictions menu to be protected by the pin to stop it being turned off????

    I have Find my Phone enabled on iphone and ipod. Could a possible thief switch off location services to stop it being tracked? If so, an update must place the location services and icloud into the restrictions menu to be protected by the pin to stop it being turned off, surely????

    Now find a way of stopping the thief removing the SIM, or simply turning off the phone or restoring it. 
    The "Find" feature is useful if you mislay the phone, but not usually of value if the phone is stolen.

  • I've tried to update my i-Tunes version after the site suggested I should following my i-Pad being plugged into it for the first time. The update seemed successful but the program would not open at all despite switching off the PC and re-starting several

    I’ve tried to update my i-Tunes version after the site suggested I should following my i-Pad Air being plugged into it for the first time. The update seemed successful but the program would not open at all despite switching off the PC and re-starting several times. I then tried wiping the original software from the computer and re-downloading from scratch. Each time I tried the download failed with a message saying “Service “Apple Mobile Device” failed to start. Verify that you have sufficient privileges to start system services” At this stage, the only way forward was to “abort” the download. This I have done now four times and the same thing happens. When I did finally manage to get an i-Tunes shortcut on my desktop, the program wouldn’t open saying: “i-Tunes was not installed correctly. Please re-install i-Tunes. Error 7 (Windows error 193)” Any ideas to resolve this?
