MDB read message queue too slow

For some reason only a small number of MDB in the pool are accessing the message queue. The queue is growing rather fast and I wish to know how I can increase the read rate of my MDB's. Should I create another bean type to read the same queue. This does not seem like the ideal solution.
          Thank you

The JMS Performance Guide white-paper contains information
          on how to configure an MDB to run more instances concurrently.
          One thing to realize is that the number of instances is limited
          by the size of the thread pool that the MDB is running in.
          You can find a link to the white-paper here:

  • Response message became too slow, after transported to Consolidation Sys!

    Hi guys,
    I have a sync interface with BPM who calls an HTTP service.
    In development system things work fine and the interface is really fast. It gets a response from HTTP service in a few seconds (also with big messages, over 2 mega bytes). After transported to the consolidation system, the response message became too slow and after 600sec it gets a timeout.
    No parameters on Integration Server and RZ10 were changed…
    Anyone knows what’s happening or have an idea?
    Thanks in advance,
    Ricardo.

    Hi Udo,
    What do you mean "the channels are not transported 1:1"?
    One thing, the difference between Development XI and Consolidation XI is that Consolidation is in Cluster.
    I need to do some extra configurations for HTTP in Cluster systems?
    Thanks in advance.
    Regards,
    Ricardo.

  • RECORDING ERROR MESSAGE-'DISC TOO SLOW'

    Every once and a while after I have recorded around 12+ tracks, I get a "Disc too slow" message with a black block at the end of the recording. The black block when played back is just a loud noise. What is this and what setting might I have wrong. I have the new IMac 27" with quad cores. The cores meter is barely moving and I don't hardly have any processors on. HELP.

    sand box wrote:
    Erik.......do you feel it is better to record direct to my external HD or the Imac HD?
    External. IF it is Firewire. USB is less suitable, but it'll do too. The startup disk is also busy handling RAM for virtual memory, so it is doubly stressed when recording to it, and will 'refuse' to record, or drop out, or say "disk too slow" sooner.
    What are the best settings for buffer and the other recording parameters?
    Depends on your machine; rule of thumb: keep it as low as possible when recording for minimum latency (32, 64 or 128 or 256), and set it higher when playing back, (256-1024) to avoid "system overload".
    The best recording format imo is 24 bit/44.1 KHz (or 48 KHz). If you record 10+ tracks that are all subtle acoustic recordings, it may ever so slighly improve sound/mix quality to go with 24/96KHz, but that will also double the overhead for the CPU. And imo the difference even then is hardly perceptible, save for the most highly trained professional ears.
    I record basic rock with 16 tracks or less and not overly complicated effects. Also I still don't understand what "flattening" of a track means. Thanx.
    Okay, so 24/44.1 is enough for that. Flattening a track means that you make a new audio file (solo the track, and bounce) that includes the plugin effects you applied to it. It is an (old fashioned) way of freeing up CPU (because you can switch off the plugins afterwards and use the 'flattened' audio file).
    Freezing provides a better alternative for freeing up CPU though. Look it up in the manual, it is a simple and effective feature.
    regards, Erik.

  • IOS7 message is too slow

    Hello, since I update my Iphone4 to iOS7 it is very slow. Writing text messages/imessages is nearly impossible. I have to waite a few seconds after typing a letter/letters till they are on the screen?
    After a restart it isn't better. The whole Iphone is very slow and there are many stops (Screen shows noch reaction) while using.

    Appears to be something about the iCloud settings that affects this. Another user on this forum suggested:
    SETTINGS > ICLOUD > DOCUMENTS & DATA. Toggle from 'off' to 'on' and back to 'off' and the speed of typing texts and emails problem is fixed...
    The only problem for me is that I do use documents in iCloud from my phone so still not entirely happy!
    Hope this helps.

  • Disk too slow / System overload HELP?

    I'm really hoping someone can help me out with this!:
    I purchased a G4 PowerBook around six months ago, with Logic Pro pre-installed. Since then, I have mixed and mastered lots of music that was recorded on a previous system and imported. I was running multiple tracks simultaneously with tons of plug-ins and everything ran smoothly on my new Mac. HOWEVER, within the last month, my playback capabilities have been severely reduced. When I try to play back even two tracks simultaneously (with just one compressor or reverb), I get the error message, "Disk too slow / System overload."
    My first reaction to this problem was to check my disk space and see how much room I had left: it turns out I have over one third of my harddrive space still available. I checked my memory capabilities and they seem to be more than adequate. I bought new virus protection, too, and ran scans to see if that might make a difference, but it hasn't. I don't understand why this is happening on a system so new. ANY ADVICE YOU CAN OFFER WOULD BE GREATLY APPRECIATED!
    Many thanks.

    It is generally not a good idea to run logic on the same drive that contains your audio files and samples. Most of the data involved with logic whether it be programs or individual audio files will be saved physically all over the place on your hard drive. At a certain point the actual part of the drive that reads the data will not be able to move around to all the little different audio files it needs to access for the session on top of running the program and whatever other software that is up. It is best to save all your audio files and samples to a fast external drive (7200rpm at least) otherworldcomputing.com has great drives that have high quality cases and the option to put any drive they have in stock into the case. (i would recommend seagate) If you are going to continue running your entire sessions off the internal drive then you need to keep up with your basic mac housekeeping. You should repair your permissions 2 times a month (use disk utility) You should buy a good directory repair program such as disk warrior. The directory is exactly what it sounds like. It keeps track of where everything is on the computer. If your directory is corrupt the computer will have to do an extra manual search to find what its looking for. If your directory is healthy your computer will make a straight shot to the file you are looking for.

  • Disc Too Slow Error

    hey everyone, im very new to Logic and overall computer based recording. i have a Tascam FW-1804 interface that im using as well as Logic Express 7. im sure this message 'disc too slow error' is fairly common, but what should i do to get rid of this problem? should i get an external hard drive? what settings should i modify to make the program run more smoothly? thanks a lot for any help or advice, i greatly appreciate it.

    You definitely need an external hard drive if you aren't already using one. The internal hard drive is already too busy running system processes, and running those plus a logic project is too much work. So you should run logic projects from an external drive that only has that one inparticular job of running the logic project. Also make sure the external drive is AT LEAST 7200rpm if not higher. Also give yourself some headroom and buy like a 500gb external. In my experience, a hard drive performs best when it is less than 50% full, so that's why you should always go a little bit bigger than what you need.
    Lastly, you should check out some external firewire RAID striped 0 solutions. This means that there are 2 physical drives that are hooked together in a way that the computer treats it as 1 logical drive. The advantage of this is that the data is split evenly between the two drives and there will be less strain on the drives. Kind of a similar concept as dual core processing in a sense.
    The only disadvantage of this is that if 1 out of the 2 drives fail, it's pretty **** hard, if not impossible to get your data back.
    What I do is record everything with my RAID because it is a lot faster, and then every once in a while will backup everything to another standard external hard drive.
    http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/
    Check out the selection there. I've got the 500GB RAID and a 200gb standard. I have never had issues with them and I highly recommend them.

  • "Core Audio Error Disk Too Slow" On Stage?

    i use logic pro on my macbook pro(2gb ram 2,16ghz) and i'm completely satisfied with this combination.
    Only when i'm playing live(electro music - loud environment - lots of sub/bass etc.) i sometimes get the message disk too slow/system overload, although i'm only playing some aiff files and some softsynths to it...
    is it possible that my external disk(lacie d2 FW400) is skipping due to vibrations or is my Sudden Motion Sensor stepping in? i disabled it already... anyone the same problems or even an answer
    thx in advance...
    Macbook Pro   Mac OS X (10.4.9)   2 gb Ram

    If you can afford it buy one of these http://www.sonnettech.com/product/temposataexpress34.html
    and an external sata drive - sonett also make them http://www.sonnettech.com/product/fusion.html
    Or any external sata drive will work if you only need the one drive. The sonett is good as it does port multiplying meaning you can have up to 10 drives running on your laptop
    Although a quicker and cheaper fix could be to try putting the lacie on some neoprene. - this will cut out "most of the" bass thats transferring from say the stage to the drive, but it wont help if the bass is really loud as it is more than likely the airborne bass that is causing the errors.
    If money is no object the sonnet solution is very good and in theory would be rock solid running in raid and mounted on neoprene.
    Just a thought....

  • Messages in inbound queue in status-RUNNING and it is too slow

    Hi Experts,
    We have a issue there are tons of messages in inbound queue in status-RUNNING and it is too slow!, hence there are more messages getting in the queue every minute.
    This is Production enviorment.
    We have priority queues
    QIN is waiting status.
    De-register will not work due to loss of messages fear
    Please advice
    thanks and regards,

    Hi,
    If the queues are hanging due to peak load at sometimes
    you can schedule following reports to restart them automatically
    (dont have to lock and unlock manually)
    RSQIWKEX - Inbound Queues
    RSQOWKEX- Outbound Queues
    Also you can save the first entry of the queue if its causing problems to process later- smq3

  • The servers gets too slow with JMS Messages

    Hi all,
          Look, Im usin JMS services, with MDB, and work good. Also i kepp a Queue to wronly messages (basiclly for comunications between R3 and Portal). Thats messages have seted a "Time to Live" equals to one day, so, they dissapair when this time are completed. But for some reasson, my server gets too slow and show exeptions of Time Out. Maybe the messages are not "killed" really, and consume memory from the server or some like that.
          The think are, that im deleting manually the Queue from the Visual Administration, later than this, the process back to keep the execution time and gets faster.
          If some know some or had this same trouble, please help me...
    Thanks in advance,
    Jorge.

    I see. Thanks for your advice
    I always had this setting on my previous devices (Sony Xperia X10 pro, Samsung Galaxy Slll) and thought it wouldn't do anything. It just got slow when it actually was updating.
    Now I turned that setting off, the wifi worked quite long again (10min) but then it was gone. Unfortunately.

  • Why am I getting this error message, "Disk is too slow. (Prepare) (-10001)"

    Hello all!  I've been using GarageBand for a while now and I've accumulated quite a few files.  Along with all of my movies and iTunes library, my internal hard drive filled up rapidly and I didn't catch it.  I received a warning message on my screen one day saying that my hard drive was nearly full and I only had a few MB available.  I'm using a 150 GB Solid State Hard Disk on my 2009 MacBook Pro (2.6 GHz Intel Cre 2 Duo, 4 GB of RAM).  I remembered reading a while back that it's better to use an external hard drive for pretty much everything when using Garageband, so I bought one.  I now have a seagate 500 GB, 5400 rpm external (USB 2.0) and I moved ALL of my movies and music over to it.  I freed up around 60 GB of space on my internal hard drive in doing so. 
    So now that I've given you a little background, let me explain the issue I'm having.  Before I noticed that my hard drive was full, I started receiving this error message:
    Disk is too slow. (Prepare)
    (-10001)
    Upon receiving this message, I was unable to do pretty much anything in GarageBand.  I couldn't listen to tracks, export to iTunes, or do anything!  All I'm using GarageBand for is editing.  My band and I do all our recording (and mixing) offsite at a separate studio and i just deliver a 2 track stereo signal (L/R) to my MacBook.  From there, I just cut the individual tracks from a block of 30-45 minutes of recording because we just record our entire studio session and mix everything there.  I pretty much never have more than two tracks and a few effects going at the same time.
    After I realized that my disk was nearly full, I consulted my brother-in-law.  He's head of the IT Deartpment at a major hospital here in West L.A. and he told me that I may have created a problem with the cache by filling up my internal hard drive and that I may still have issues with performance even after I free up space.  He then told me that I may need to reboot my MacBook a few time to "free up the cache" (or something close to that, sorry guys I'm not that tech-savvy).  It seems he may have been right, as I'm still experiencing the same issue.  I rebooted around 10 times overall to no avail.  I'm still using my internal hard drive to store the files that I'm working on (temporarily) because USB 2.0 is way too slow for my liking, when using GarageBand.
    I've read quite a few articles on this offering solutions such as:
    1.  Do a complete Uninstall and Reinstall of GarageBand
    2.  Clone my hard drive to my external, format it, and reinstall everything back on it
    3.  Get a hard drive that supports Firewire 800 (The HDD I bought is USB 2.0, but it has two USB cables to increase speed, but I only have 1 port and I tried      a powered USB Hub, but this HDD won't work with it for some reason).
    4.  Use different editing software.
    5.  Take it to Apple!
    Will any of these things fix my problem?  Are some better than others?  Before I do anything, I wanted to ask this question on the furum to see if anybody had an easier (or cheaper!) solution.  Any suggestions, tips, or advice would be much appreciated, as my band is starting to get on my case about finishing our CD!  Thanks...  

    Have a look into the Preferences folder (YourUserFolder/Libraries/Preferences/) and trash all Logic preferences.
    You'll have to setup the program again.
    cheers

  • "Full Screen Mode" in Adobe Reader XI for Windows 8 loads way too slow!

    I recently got a new laptop with Windows 8, after having used Windows Vista for years.  I installed Adobe Reader XI for my new computer.  Before, I used Adobe Reader X on Vista.  I used Adobe Reader "Full Screen Mode" to read the nice-looking Bible chapters I created with internet audio from Biblegateway.com.  In Vista, the "Full Screen Mode" appeared quickly, before the audio fully started, so I could see the text in time for the reading. 
    However, with Windows 8, "Full Screen Mode" takes around 5-10 seconds to appear at all, and a black screen is present throughout the wait.  It does the same thing when I hit "escape" to exit "Full Screen Mode" as well.  I even uninstalled Adobe Reader XI from my new laptop, and tried using Adobe Reader X, even though it is not recommened by Adobe to do that on Windows 8, in order to test the speed of "Full Screen Mode" there.  Adobe Reader X had the same problem!  I do not know if this can be fixed, but I am pretty unhappy about it!  I enjoyed the "Full Screen Mode" with my PDF chapters and the online bible audio!  Finding that function for the first time with Adobe Reader X was a delight for me!  It gave the reading a theater feel!
    Has anyone else here had a similiar problem with "Full Screen Mode" loading way too slow on Windows 8?  I am very disappointed!  If this cannot be fixed by a user, is there a place to complain to Adobe and make a recommendation for software improvement?  Thank you!

  • I'm getting "the disk is too slow (prepare)" message

    I'm getting "the disk is too slow (prepare)" message when trying to do literally anything in garageband right now, even with all other programs shut down, correct energy saver settings, and only one audio track in garageband.
    Everything else on my macbook pro is running fine, iMovie, Safari, etc... so it seems like a garageband problem to me. I updated garageband, have reset computer multiple times, I don't know what else to do... it feels like garageband is keeping all of my recent projects open in the background at once, but when I check my windows, that is apparently not the case.  Any help?

    Anyone have any ideas to help?

  • CoreAudio: Disk is too slow (Prepare)   error message?

    Hi,
    In a Logic project I'm currenly working on, each time I open the file and press play for the first time, Logic hangs for 15 seconds or so and gives me this error message:
    CoreAudio: Disk is too slow. (Prepare)
    (-10001)
    If I then stop, rewind and play again everything works fine. It only happens after this specific project is first opened and played.
    Any ideas what this could be about? Disk is definitely not too slow. I get the same error if I start at a one track passage or bypass all effects and then play.
    The file in question contains imported AIFF files, imported MP3 files as well 100 or so MIDI tracks.
    Logic version is 7.2.1.
    Thanks,
    Maarten

    It's in the energy saver preferences, uncheck spin down drive when idle thing.
    HOWEVER, I posted this in another post, there is a bug where external firewire drives are still getting spun down with this checked off. I reported the bug to apple, they asked for more info, they said thanks, and last I checked the bug was still open, which tells me it wasn't reported before, and they're actually working on it.
    So don't be surprised if unchecking the box doesn't fix it for your external drives.
    The trick I use to get around it is simply double click the file on the external drive to open the song. That spins the drive up pretty good because you have to open a finder window which has to list all the folders etc...
    hope this helps.
