Lots of Clean/Expire, few Connection threads

My application is talking to lots of RMI Servers. I think I am either holding onto some remote refernces... or I'm "churning" through a bunch real fast. Its a rather large application and these remote references could be... in many many different places.
Anyway... there are:
1 RMI RenewClean thread for each of the remote RMI servers..
1 RMI Connection Expire thread for each of the remote RMI servers.
However I only have 13 RMI Connection threads.
To me this looks like I'm "churning" through remote connections real fast.. and the RenewClean/Expire threads aren't dieing off fast enough..
Does everyone think I'm on the right track? are their ways to help the renewClean and Expire threads to die off faster? currently they add up to over 300 threads... makes my appliction run out of memory and that I get sad..:(

There will be one renew/clean thread per remote endpoint and one connection expire thread per channel. If you have 140 servers this makes 280 threads. The renew/clean thread dies once the endpoint is removed by DGC of all stubs to it. The connection-expire thread does not die. You could play with the connection-expiry times and DGC settings, and there are clues in my book or on the RMI mailing list, but probably you really just need more memory to deal with 140 servers. That's a lot.

  • A lot of questions but few answers.  That is a fact.

    A lot of questions and few answers.  That is a fact.  My question is about deregistering a kaputt PC, and synchronizing iPod and iPod with a replacement PC w/o losing content.  I had a Toshiba with tummy trouble sychronized with and iPod and an iPad.  I bought content on all three and added content from CDs I already had.  They synchronized fine.  I deleted iTunes on the troubled Toshiba and installed it on a new Gateway.  The Gateway has far less content on iTunes and threatens to delete content from the iPod or iPad if I synchronize.  All I want to do is get all the shtuff together again on at least the Gateway and the iPod, preferably the iPad also.  Also, how to deregister the kranky Toshiba given that iTunes is deleted on it.  Why am I appealing to someone out there with time on their hands.  Doesnt Apple employ people for that?  If not, its high time they did.

    Apple does employ people to help with technical problems. They're called Apple Technical Support, available by phone (use the Contact Us link at the lower-right of any Apple web page), and Geniuses, available at any Apple Store.
    As to your questions, I'm not completely clear on where you have what content, but if it's all on your iPod or iPad, then you can transfer the content back into iTunes (a subject which, by the way, has been covered here many times already). For content purchased from the iTunes Store, see this support article:
    http://support.apple.com/kb/HT1848
    For content not purchased from the iTunes Store, check out this post from Zevoneer for some iPod/iPhone media recovery options:
    http://discussions.apple.com/thread.jspa?messageID=10570955#10570955
    As to your question about "deregistering", I presume you're referring to authorization to the iTunes Store. It would have been best to have deauthorized the Toshiba before you uninstalled iTunes. You cannot yourself deauthorize a computer that's not working or to which you no longer have access. You can authorize a total of up to five systems, so it's probably not really important that you deauthorize your dead unit now. Once you reach five total authorizations, a button will appear in your iTunes Store account that will allow you to deauthorize all your systems, so that would at that time recover the now-useless authorization.

  • Unable To Reserve Lots that are Expiring Later on the Current Date

        Hi Guru's,
           An item has an expiry date of 12-APR-2015 23:59:59.But it got expired, from 12-APR-2015 00:00:00 the lot shows an (Available To Reserve) ATR as 0 on the Onhand Availability , although the onhand quantity and Available To Transact (ATT) show the quantity.As per expiration date expiration of lots should starts from the date stamped on it and the timestamp doesn't really play a role.
    Seen the note:  Unable To Reserve Lots that are Expiring Later on the Current Date through Auto Detailing get Error of Could not Query Reservations (Doc ID 1193423.1).
        But the solution provided is confusing, as in a R12.1.3 inventory implemented environment we cannot find the options to set picking rules with Lot --> Exp Date >= Expression --> Trunc(sysdate).It would be great if any body can let me know the solution.

    Hello,
    InContext Editing does no longer support HTTP authentication method, as the release notes state. As a result, users will not be able to edit sites, folder or pages that are password protected.
    Currently we do not have a workaround for this issue and we recommend removing the password protection. The issue has been added on our feature list but we do not have a proposed timeframe to fix it.
    Thank you,

  • Lots of "Cleaning Up" during render -- problem?

    If I twirl open the triangle thingy during a certain project, there's a lot of "cleaning up" stages. What is this? Is it bad?

    I doubt you could really optimize it. You could try to pre-compose some of the glows in cropped comps (if they only affect certain parts of the image and that is feasible), so this way you can limit the dilation/ expansion of pixels in all directions, but that's probably as good as it gets. As an alternative you can of course always find alternate third-party effects for such things, which may prove more processing and memory friendly. E.g. Sapphire has several different glow plugins. Or you use tools like Magic Bullet Looks that have internal diffusion/blur/glow operators running on the graphics card...

  • HT5035 can i pls see my apple i tune card purchase history? it appears that in end of year 2013 i have about $163 in my gift card balance, but this yr becomes zero. i have purchase lots of apps these few days and have no idea all the $ has gone from last

    can i pls see my apple i tune card purchase history from 2013-2014? it appears that in end of year 2013 i have about $163 in my gift card balance, but this yr becomes zero. i have purchase lots of apps these few days and have no idea all the $. i want to find out where the $ go. i have just add $50 in for my itune card.

    You can't see your card redemption history - you can try contacting iTunes Support (these are user-to-user forums) but they might not be able to help you : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page
    You've checked the purchase history on your account ? If you log into your account on your computer's iTunes via the Store > View Account menu option, you should then see a Purchase History section with a 'see all' link to the right of it. Click on that and you should then see a list of your purchases

  • I'm facing a lot of problem to get connected to 3G speed on my iPhone4 . And also I hardly get 2g speed . I'm done with all the checks as network reset , clearin cache n cookies even . Thus request to clear this heck of a issue

    Facing a lot of problem in connecting to 3G speed on my iphone4 . Done with all the checks as network reset and also done with clearing cache n cookies still the problem is same . I hardly get 2g speed even . Thus I request to help to fix this problem.

    Your code is absolutely unreadable - even if someone was willing to
    help, it's simply impossible. I do give you a few tips, though: If you
    understand your code (i.e. if it really is YOUR code), you should be
    able to realize that your minimum and maximum never get set (thus they
    are both 0) and your exam 3 is set with the wrong value. SEE where
    those should get set and figure out why they're not. Chances are you
    are doing something to them that makes one 'if' fail or you just
    erroneously assign a wrong variable!

  • How to clean all airport connections and start setting from the begining

    I made some mistakes setting airport and now i cant get rid of thosе  setting to manage my connections "from the clean sheet". How to delete my network settings?

    If you are referring to the wireless network settings on your Mac computer, it's a two step process.
    Step One
    Open System Preferences (gear icon on the dock)
    Open Network
    Click on AirPort on the left
    Click Advanced at the lower right
    Click to highlight a connection in the list
    Click the - (minus) button at the bottom of the list to delete the connection
    Repeat as needed for other connections
    Step Two
    Open Macintosh HD > Applications > Utiities
    Open KeyChain Access
    Locate a listing with name of the wireless network and click to highlight it
    Click delete
    Repeat as needed to delete all networks that you don't want
    If you have an Apple wireless router and are referring to the wireless network settings on that device....
    Open Macintosh HD > Applications > Utilities > AirPort Utility
    Click Manual Setup
    Click on the Wireless tab just below the row of icons for the settings page
    Click Update after you have made the changes that you want

  • Users not being notified AD password is going to expire when connecting to corporate wireless network

    Hi All
    In my company we are still on Windows XP.  Every month there are hundreds of calls generated for users who connect primarily to the company network via our Corporate wireless and the passwords expire but they are not notified it is going to expire. 
    This means when users passwords do expire they are then not able to connect to the corporate wireless and the only way to get them up and running again is for them to call the Service Desk and they will then reset the password back to what it was previously.
    This has been logged to the companies 3rd line team and they are telling me there is no way to resolve this.  I find this pretty unbelieveable as WinXP is a long established Operating system across most companies in the world and having the above
    scenario is a massive security risk.
    Does anyone know of or have experience of this?

    Hi,
    You can use Powershell script to send email notifications on AD user password expiration.

  • I used window cleaner a few times on my iPhone what happens?

    I recently got an iPhone 6 for my birthday. It got dirty a few times so I used window cleaner on the front of the iPhone because it said anti-streak and anti-fog. I thought that this would prevent it from fogging up (which it has) but recently I was reading on the net how to clean iPhone's and it said not to use window cleaners on it. I did use it on the front and back of the phone. Cleaning every part of the exterior of the iPhone with it. Has this damaged the phone in any way. Have I lost my ole-phobic coating and is there a way to restore it? Please help!

    You should get your screen  checked by visiting an Authorized Apple Service Provider or Apple Store and ket them have a loo at the screen, just to be sure.

  • Randomly (Edit: when loading pages w/ lots of content: pics) losing connection to router (WRT54GC)

    There's just too many threads about connectivity issues, so why not post another one I'm connected directly (cable) to my wireless WRT54GC router and sometimes I lose connection with the router. There are more than one computer connected to the router, when it happens, all computers lose connectivity. So yeah, router is the problem. It seems to happen randomly, about 15 times a day. Can't access the router. Then after a minute or so the connection comes back. It happens so often that I just power down the router then power it up right away and everything is back to normal. When it happens, lights on the router are flashing like everything was normal. Firmware: v1.05.7 Edit: title.
    Message Edited by bZEK on 08-05-2008 06:37 PM

    You are not alone.  My WRT54GC has been doing that since I got it.  I bought it for the 802.11G connectivity as I was using a D-Link with only 802.11b.  My house is wired but I have 2 laptops that are wireless, hence the switch to the faster wireless...  Anyway, I actually switched BACK to the D-Link for a time because I was so frustrated with the dropped connections (could ping the router, but router wasn't going out) on both my wired and wireless PCs.  This happened to me on every firmware version I've used with the WRT54GC.  1.05.7 happened the least, though I started avoiding the pages that caused it to drop.  It just happened again today while in a video call in Skype, which was a first.
    So I feel your pain, and don't think anything but a new fixed firmware will help.  I've tried IP adjustments, MTU adjustments.  I am doing a MAC address clone, since my ISP still locks to my old P3 450MHz PC from when I first got broadband that I hardly use anymore.
    So I, too, am looking for a fix.  I always thought Cisco/Linksys would be a safe bet...

  • This document has expired/not connected to the internet

    We have a set of documents that we are not able to access
    lately due to these 2 errors:
    "This document is locked. Your permissions to view it has
    expired. If you want to open this document, contact the person who
    sent it to you and ask them to extend the expiry date."
    and
    "This computer must be connected to the network in order to
    open this document. Connect this computer to the network and then
    try opening the document again."
    The administrator of the document has since looked in their
    account to make sure the documents are still valid, in which they
    are. We are however, not sure if the administrator needs to upgrade
    their personal account as they have been using the free account,
    and has not been notified that the account is no longer
    valid.

    Hi. Thanks for the response.
    I have previously used the set of documents without any
    problems. This inaccessibility is a recent development. I do not
    believe that there had been any time lapse between the first
    sharing and access attempt.
    The administrator has removed my email address and re-added
    it to her recipient list. Upon trying to launch the document again,
    I receive the same error.
    We are accessing the document through a link embedded in the
    protected file, not logging onto the site. I've also tried logging
    onto the site, and then double-clicking on the link provided in the
    document. Both ways do not work. I'm using Mac OS 10.5.6 and have
    used Acrobat Reader 8 & 9 as well as Acrobat Pro 8.

  • ORB Connections/Thread pool

    Does any one know the max number of connections that AppServer 7 can handle. Any idea about the max size of the thread pool?

    I have finally found the solution. The solution was to get hold of the ORB of the app server. Hence the following 2 lines did the trick.
    org.omg.CORBA.ORB orb = null;
    try {
    javax.naming.Context jndiRootCtx = new InitialContext();
    orb = (ORB)jndiRootCtx.lookup("java:comp/ORB");

  • Skype is having a few connection issues. (Windows ...

    Uhm, I'm pretty sure I have the latest skype, but whenever I've tried to access home for the past few weeks, it  just doesn't do anything, is has an internet issue, same with trying to sign into it with facebook, it has a connection error and says.  
    "Sometimes the internet gets a bit sleepy and takes a nap. Make sure it’s up and running then we’ll give it another go."
    The thing is, my internet is fine, I can sign into skype, but I can't access home, or try to sign in with my Facebook.

    What is the version of Internet Explorer installed on your computer?
    In Internet Explorer go to Help -> About Internet Explorer.
    What do you see when you open this link in your Internet Explorer?
    https://apps.skype.com/home/
    P.S. Please, don’t say that you are not using Internet Explorer. This is irrelevant. Skype depends on Internet Explorer.

  • Changed Database Service Tier resulted in lots of "Timeout-expired-errors"

    Last night I changed database service tier from Web Edition to Standard S0. Since then we are getting a lot of errors like this:
    "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."
    Before the change we had no such errors. I have tried to make a new deployment of our cloud services but it doesn't change anything. It still fill the error logs with timeout-expired-errors and the site itself seems to be significantly slower than before.
    What's the problem? I assume the Standard S0 service tier should be sufficient in performance. We don't have much traffic on the site. 
    Hope someone can shed a light...

    Folks we know that changing business models is a hard thing to do.  In the Web/Business case, you pay on size of the DB and you get whatever performance we have at the time.  Sometimes this is great, other times this is ok and sometimes performance
    is very poor.  Customers have given us feedback that this unpredictable performance is very difficult to deal with.
    Using this feedback as a key input, the business model for Basic/Standard/Premium is $/perf.  As Jan points out below, understanding what resources your consuming is a great first step before moving to B/S/P.
    Your mileage may vary here.  Many customers see a decrease because of this business model change.  Others see no impact, and some will see an increase if their DBs are very small and consume a lot of resources.
    Jan, I and the team would be happy to help customers move into the new business model.  To have great conversations will need some customer specifics that aren't best shared in a public forum.  guyhay@microsoft is my email if you'd like to have
    that conversation.
