Starting the server takes a long time due to the storage of JMS persistence files

Hello

We use WebLogic 9.2 on a windows machine.
Recently, we have improved our request to work with JMS.
We are on 2 different servers in a cluster using 2 JMS servers and works with distributed destinations.
We use file storage as our persistence store.

Recently, we found boot server takes a long time because of the actions that are performed on the storage of files.
Analysis of this problem, we have seen that the size of the file is of ~ 2 GB.
We understand that the file size does not fear (unless it is compacted manually), and its size matches the largest number ever of pending messages in the queues (as a mark of high tide).
We shot also store debugging, using weblogic. Debug.DebugStoreIOPhysical and we saw a lot of recovery after newspapers file storage is open.
We have checked and checked our JMS transactions are completed successfully. We also checked that the current messages and number of courses is 0.
We stopped the server gracefully, check that there are no messages pending.
However, several times takes start server ~ 30 minutes due to heavy work on the persistence store.
Compaction or remove storage of files eliminates the delay.
However, we want to avoid the manual operations whenever we want to start the server.

Please share your ideas.

Thank you
Itsik

The only suggestions I have off the top of my head are:

* Ensure (1) the host system has at least 2 GB (the store file size) memory physics in addition to the memory used by the current process, and (2) the host system is not rebooted between each restart WebLogic. If you ensure that both of these, then the operating system puts implicitly cached content of the file of the store in memory even between boots - when WebLogic starts subsequently storing files, the o/s should be the content of the file much more quickly.

* You can move to a JDBC store. Runtime JDBC store performance are lower, but since you have generally has only a small amount of records to retrieve, startup performance should be higher in this case.

* Not that it helps your case, but it happens that we have significant performance improvements of starting process for a future version (if all goes well a near future release).

  • Server takes a long time to send the verification email

    I created a registration with verification e-mail systemn page but the problem is that mail takes like 30 minutes to 2 hours to deliver is one we know what we can do about it

    There are no that you can actually do by e-mail delays. PHP mail() hands function simply the message to the transport agent of messaging from the web server (MTA), usually of Sendmail or Exim. What happens after that depends on the queue in the MTA. There are also problems of latency with your ISP. Most e-mail programs allow you to check the headers of the message, which usually will tell you the time that the message was received by different MTA along the road. Looking at them, you can get an idea hence the deadlock is underway, but it is not that you can do about it apart from moving to another ISP or hosting company.

  • Visual Studio 2008 Pro takes a long time to start after the installation of measurement Studio 2009

    After installing Measurement Studio 2009, I noticed that it takes a long time (30-60 seconds) to open a Visual Studio project.

    I do not have an internet connection on my development computer and suspect he might be waiting on some kind of operation of the network to time out.  I had problems with Visual Studio in the past as well and had to work around them by adding entries to my hosts file (to redirect some addresses of Microsoft to the local IP address - this causes network operations to expire immediately).

    Just curious if anyone has encountered this kind of slow startup time and found a solution.

    Thank you!

    I have a Toshiba Satellite M300 PSMDCA - 01800C and there are some problems with it.

    First of all, when you start the computer, it takes a long time to start and activate Outlook.
    I am running Windows 7Home Premium.
    Computers arrow where I bought the computer told me that it can take up to three hours to go back through each process at startup?

    Is it normal that all I wanted was a simple portable easy fast, but it seems that I am stuck again.

    Also, when I go back to the computer, even after some time the mouse it does not provide new and pushing the Start button just a blank screen. Alt + Ctrl + delete, then he activates Windows again and then after having put my password and I have to wait for that be again loaded everything that takes so long. Any ideas?

    Also I often get the message when the computer starts "error has occurred in Toshiba PC Health Monitor. He will leave the application. "Main.frm.cpp (184). Any ideas?

    Quite often when I am scrolling with the mouse, the screen will turn black and flash and a message «the NVIDIA display driver... couldn't Reg...» "and he will correct itself after awhile. Frustrating!
    Quite often when scrolling on the websites of the page I'm going to freeze?

    I use MS Office 2010 and there is a problem trying to save Word documents and a message comes up with "a file permission error.

    Any thoughts? Thanks, Shirl51

    This nonsense!
    The system should boot up quickly my laptop needs 30 seconds to start.
    In my opinion, the system is screwed

    In your case, I recommend to reinstall the system.
    Did you create the recovery disk?
    If this isn't the case, I think that detailed instructions should be placed in the user's manual.

    After the recovery of disk has been created, restore the system, BUT save the data before doing so because the recovery disk would be to format the HARD drive and you lose data!

  • After that effects 2015.3 takes a long time to open, left after the closing process running

    My AE 2015.3 takes very long time to start. He gets the message "Initializing MediaCore" on the splash screen and then hangs there for 1-3 minutes. It opens also a ton of "Adobe After Effects 2015.3" tasks in the Task Manager, leaving them running even after I quit the program.

    Here is what my task manager looks at this time (no AE running)

    AECrazy.jpg

    So far, what I've done:

    1 uninstalled all Adobe software, including Adobe CC Panel

    2 uninstalled all 3rd party plugins, scripts, and presets

    3. manually deleted all files from adobe - complete cleaning

    4. re-installed AE and some other programs

    (all with reboot between the two).

    No difference.

    Help?

    Apparently, nVidia GeForce drivers are at fault. The break of v368.81 WHQL way Adobe applications communicate with Media Core, make After Effects, first and slow speed Grade, leaving the additional processes in their wake and spoil some plugins 3rd party.

    Returning to a previous driver nVidia solved all the problems.

  • The system preference takes a long time to load

    As the title suggests, end of 2013 (10.11.4) System Preferences on my iMac takes a long time to load, even after a fresh reinstall and/or reboot (tried both). It takes about 20 seconds to one minute each time to open (except when I close it and immediately open it once again, as it is always loaded in memory). This problem existed only after the upgrade to El Capitan, and I saw many other people with iMacs with the same problem. I tried to remove cache for before system preferences files, but that did not help at all. I don't have a FileVault if it makes a difference, even if I did before reinstall, but never turned back (persistent question anyway). Any recommendations would be useful. Thank you!

    Data sheet:

    iMac (end 2013)

    Intel Core i5 at 2.7 GHz

    8 GB 1600 MHz DDR3

    1 TB 5400 RPM HARD DRIVE

    Intel Pro Iris 1536 MB

    I found it is the State of affairs in 10.11 if running a HD spinning.  Don't feel alone.

    I suspect that it is a function of low priority in the memory compressed algorithm.

  • Still burned DVD takes a long time to load into the reader

    I created a DVD in Encore CS3.  The final DVD is approximately 60 minutes and has 4 menus created in Photoshop CS3.  I purchased the Dolby converted in first and used this file as PCM format indicated by a friend vs.   The DVD works fine but takes a long time to load in one of my DVD players.

    A Sony player, it takes between 40 minutes and up to 70 seconds to load and play the first menu.  Each time is different.

    (This same drive load purchased in-store Hollywood style DVD in about 15 seconds on average)

    In another Sony player my DVD on average about 25 seconds

    A Panasonic player, it takes about 15 seconds

    In a portable player from JVC, it takes about 8 seconds.

    That is what it is?  This DVD is created for replication in a large number, but I'm afraid the long loading time is a problem and you want to solve this problem before sending it to the wide for replication.

    Help, please

    Thank you

    EDM

    EDM,

    One consideration is that there is no DVD drive certified to play any burned DVD, only those press/replicated. Most do and do as well, with provisions, but some don't.

    Now for these provisions. High quality blank media will get a closer all the success, just like using a slower speed of the burn, as the max. These two considerations will get a close, as it is possible.

    What brand of blank media are you using? Verbatim and Taiyo Yuden are about as good as it gets.

    How fast you burn to? I would look into a speed in the middle of the range permitted by the combo of speed by the media and the burning speed. Slower is better than more fast.

    As Stanley, there may be differences with r and + R media and players. There has been much more a problem, but some players still might prefer a vs the other.

    Finally, when you say "replicated", do you mean that you send in a DLT to make a House of replication a glassmaster, where the DVD is going to be in a hurry? If Yes, these replicated discs will be like the Hollywood DVD and will be NOT burnt, as was your test drive. The question will be moot with these, as they will be DVD-videos, where your burned DVD is really a DVD - ROM.

    Good luck

    I tried to increase the number of cells under "App settings-> options-> warn if greater than 5 000 000 000 data form. I even tried to '0 '. Nothing works planning 9.3.1

    Hello

    That's how I've always changed the number of cells, after which display the message on the forms of data.

    There are 2 levels of adjustment. You can configure the application level, but users must select "Use Application Defaults" in the planning of the preferences of the user parameters. To do this, use the file-> Preferences and select schedule.

    Otherwise, you can set the value of the number of cells at the level of the user for ' warn if data form more xxxx ". It should solve the problem. This should be the installation program if you have not selected checkbox default Application for the user in the preferences of planning.

    If nothing else works, it is very difficult to guess, I would open a SR with Oracle.

  • Programs to freeze or take a long time to respond

    When I run new programs that they can take a long time to start or they freeze. This happens sporadically, but enough to be a nusiance. I followed all the steps listed under the section "fixit" of Vista Hoem premium and the maintence of the Vista Help sections section: I've defragmented, wipe the drive, run the system performance (overall score of 5.4 due to memory all other 5.9), has increased to 8000 MB swap file and several other steps. If I try to click on the program, while the little circle turns, my screen becomes a pale white and I can't do anythingfor several minutes

    Has anyone else had this problem and solved? I have a lot of space (free 400 G) and 4G of RAM.

    This happens anytime, not only after the machine has been for some time, given the previous answers to this question.

    Hi Daniel,.

    What application are you trying to access?

    You can perform the clean boot, and then check if the problem persists. It will start Windows Vista by using a minimal set of drivers and startup programs and helps eliminate software conflicts.

    The following link has steps showing how to perform the clean boot: http://support.microsoft.com/kb/929135

    Note: Please make sure that the computer is configured to start as usual according to step 7 of the article: how to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7: http://support.microsoft.com/kb/929135
