Painfully slow access to admin console (how can I fix it?)

Hi,
I'm using using Sun Java System Web Server Version 7.0U4 B12/02/2008 02:17 running on CentOS (Redhat EL) release 4.4.
The problem is that using the Admin Console (on port 8989) is painfully slow. It takes minutes for each page to load, but they do usually load.
Any ideas on how to fix that?
There are some other things going on that might be related and helpful to know:
I get certificate errors when I access the Admin Console (e..g, IE complains about a mismatched address). I've tried following the directions to install the certificate in IE7 and FF3, but neither has stopped bothering me about the certificate error.
I have the server behind a firewall which allows all outgoing traffic and select incoming ports to the server. The firewall also maps a public IP address to the server's local IP address (e..g, 10.10.10.8).
If I access the Admin Console locally via the LAN address (https://10.10.10.8:8989) it is no longer slow, but I get booted back to the login screen very frequently (e.g, every minute or two of casual browsing through the console), and I still get the certificate error
We haven't given the server a name, but access it by IP address, and the virtual server configuration in the Admin Console is name "localhost.localdomain"
Any help and suggestions would be greatly appreciated!! I've tried searching for solutions several times, but haven't succeeded.
Thanks,
Tim

Thanks for the thoughts

sounds more like some network issues. are you running your browser on your centos 4.4 as well ? also, did you try to connect using your IP - some thing like https://<ip>:8989 ?
No, we're not running the browser on centos 4.4. We're runing browsers on laptops, connecting both offsite via public IP address and in the office via both the public IP address and the LAN ip address.
Yes, we're using the ip address as you demonstrated. This machine does not have a domain name attached, so we only connect via ip addresses (mapped public or LAN)

I've tried following the directions to install the certificate in IE7 and FF3, but neither has stopped bothering me about the certificate error.it is not a certificate error. web server 7 admin server uses a self signed certificate . this is necessary step. however, IE reports a warning when it sees a self signed certificate. it wants you to know that it does not understand who sent this certificate. you need to create an exception - saying that you know what you are doing then there won't be any certificate error ..Okay, I'll look for how to do that, but so far I've only found instructions for how to install the certificate in the browsers, and unfortunately, that hasn't made a difference.

sounds like some network misconfiguration - outside the scope of this forum.I cannot rule that out, but other servers/websites seem to work fine with this same setup. Although, only this server is using https

if you want to increase this time out, you could do so by manually editing <install-root>/lib/webapps/admingui/WEB-INF/web.xml and change the value for session-timeout to say 600 (for 10 minutes).. . pl . note that this is not a supported way and you could potentially leave others to use your session if you are careless. but, if you know what you are doing .Thanks I did that. It surprises me that the default timeout appears to be 1 minute.

    Hi,
    Please go to IIS Manager (Switch to Content View) to check the files there:
    Expand Sites > Exchange Back End > 15.0.620.29 (my Exchange server is Exchange 2013 CU1). Please check whether there are any file folders under themes and Scripts folder. If there is no folder there, please copy the whole folders "Scripts"
    and "Themes" or the entire folder of 15.0.620.29 (cu1) folder from Exchange Installation Path /ClientAccess/ ECP/ CU1 folder in a working machine(the same Exchange version) to the update folder on same location.

  • My mac mini is running very slow all of a sudden, how can i restore it's speed?

    my mac mini is running very slow all of a sudden, how can i restore it's speed?

    This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
    If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running a program at the instance of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
    Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait about a minute. Then paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
    You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
    The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking  anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
    Triple-click anywhere in the line of text below on this page to select it:

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
    Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
    If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important.
    If you're not logged in as an administrator, you won't be prompted for your password. The test will still run. It just won't do anything that requires administrator rights.
    The test may take up to a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. There is no indication of progress until it's done. Wait for the line "[Process completed]" to appear in the Terminal window. If you don't see that line within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
    When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
    If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
    When you post the results, you might see the message, "You have included content in your post that is not permitted." That's because the forum software falsely identifies something in the post as a violation of the terms of use. If that happens, please post the results on Pastebin, then post a link here to the page you created.
    Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

    The hotmail address i use for my apple ID was hacked and i no longer have access to it, this is stopping me from accessing any of my icloud or itunes. how can i fix this?

    Thanks, I appreciate the help.  I think this is one of the problems Apple is creating by changing the OS so often. I had fomer colleagues at [a major aerospace contractor] who told me that so many original files were ultimately lost because of the deadly change in the "Save As" operation that they are now afraid of every OS update. Apple has badly damaged their support base with that very prominent company (they won't update now until they've fully examined and understand changes in the pre-conditioned nature of OS computer functions), and they are a whole lot less enthaled with Mac-related equipment/software. Can't blame them, I too used orginal files that way (as easy-to-use templates), and lost some important files before I realized what was happening (to late to revert). Companies should not have to retrain employees each time an OS gets an update, it's can be very expensive several different ways. They learned a painful lesson with that one. And because I'm now retired and don't use multiple devices, I need iCloud like I need a hole in the head... but I'm told there's no way to keep Apple out of my computer. Fortunately, because of major problems when initially installing Mountain Lion, one hold-over of the hardware/software damage I experienced was that iCloud can no longer access my computer even though everything else is working fine again. That was the only "good luck" I had as a result of that expensive nightmare.

  • My MacBook Pro is running really slow - how can I fix it?

    my MacBook Pro is running really slow - how can I fix it?

    Things You Can Do To Resolve Slow Downs
    If your computer seems to be running slower here are some things you can do:
    Start with a visit to: OS X Maintenance - MacAttorney.
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion/Mountain Lion
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Repair the Hard Drive - Lion/Mountain Lion
    Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    Suggestions for OS X Maintenance
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
      1. Carbon Copy Cloner
      2. Data Backup
      3. Deja Vu
      4. SuperDuper!
      5. SyncTwoFolders
      6. Synk Pro
      7. Synk Standard
      8. Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac maintenance Quick Assist.
    Referenced software can be found at CNet Downloads or MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

I have the link the kid used (http://www.ihackintosh.com/2009/05/how-to-hack-the-user-password-in-mac-os-x-wit hout-an-os-x-cd/) Apparently he used hack 2. HELP PLEASE!

    Not sure why you can't delete that account. If you have admin privileges, you should be able to. Sounds like you only removed the Home Folder for that account.
    You should highlight/select the account you want to remove and then click the minus button. Might need to unlock the padlock with your admin password.
    Have a look at these articles from Apple, if necessary.

  • Cannot access the Admin Consol Tasks

    Hi,
    When I go into the Admin Screen on SAP BPC I cannot access the Admin Consol Tasks but I can access the Web Admin Tasks and my excel is working fine. 
    Logoffed and retried, same problem.
    Working on Version 5.1 SP4, Excel 2003.
    Regards
    Dean

    Hi,
    There can be 2 reasons for you not being able to access the Admin Tasks. I would request you to check the below things.
    1. You need to check the Task Profile for your user ID and verify that you have all the necessary accesses.
    2. When you login to the Admin screen, make sure that some Application is selected.
    Hope this helps.

  • HT1338 I updated my MacBook Pro with Mountain Lion and now it is starting slow and opening with some of the programs. How can I fix the problem?

    I updated my MacBook Pro with Mountain Lion and now it is slow in starting up and loads a number of probrams. How can I fix the problem?

    Have you tried starting in Safe Mode and see if the slowness still occurs?
    Restart holding the "shift" key.
    (Expect it to take longer to start this way because it runs a directory check first.)
    If this works look in System Preferences > Users & Groups > Login items and delete any third party login items (-), you can always add them back with the (+). Also look in /Library/Startup Items. Nothing is put in that folder by default, so anything in there is yours.
    Reboot normally and test.
