How many statement can one connection create?

Someone said that most jdbc driver support only one statement in one connection?

Someone said that most jdbc driver support only one statement in one connection?Either wrong or taken out of context. JDBC 1.0 supported multiple statements per connection.
What varies is support for 'active' statements be connection. So if you are trying to get two result sets from two different statements that both use the same connection your results can vary. JDBC 2/3 is supposed to support this but you had better test it first.

  • Out of memory error - JS Runtime: How many users can one connect?

    Not talking video here.  Talking interactive apps, like chat.  Ours crashes at about 500 connected users.  When I report this I'm told "make sure you're not creating too many objects serverside" or "increase the JSRuntimeSize setting in your application.xml file to the max".
    Have now done both of those things but still get this out of memory error.  Let's say I optomized my app and got 100% more connection capacity.  That would be 1,000 connected users - still nowhere near enough.
    Are my dreams of 6,000 or 10,000 connected users enjoying all of the fruits of the FMS interactivity pipe dreams?  Is it not meant for sessions of that size?  Where does one find documentation or advice or application assistance on this issue?
    How do large social media applications connect so many people concurrently.
    Thoughts appreciated.
    Thanks

    Yes.  I'm using the max.

    Don't think 100MB or 200MB would be valid settings.

  • How many Airdisks can one connect?

    Hi all, i cannot seem to connect more than 2 disks to my base station. However i do remember reading somewhere that this should be possible.
    I hooked my disks up via an external powered usb hub; if i connect 3 it just shows up 2, but if i disconnect one that is visible the other one is recognized just fine.
    So to me it seems to be or a power issue, or something in the base station itself, but i can't figure it out..
    All ideas appreciated!

    I have three disks attached to a powered USB hub. I haven't had any issues. The disks vary in sizes from 160GB to 1 TB.

  • How many clients can be connected to an Access Point

    Hi friend,
    I want to know how many clients can be connected in Cisco AP 1140.
    Best Regard,
    Marco.

    Hi,
    As Stephen mention the best answer is it depends.
    What you need to keep in mind is that wireless is halfduplex and a shared medium and due to this the bandwith will go down per client.
    http://www.cisco.com/en/US/products/hw/wireless/ps430/products_qanda_item09186a008009483e.shtml
    Q. How many clients can associate to the AP?
    A. The AP has the physical capacity to handle 2048 MAC  addresses, but, because the AP is a shared medium and acts as a wireless  hub, the performance of each user decreases as the number of users  increases on an individual AP. Ideally, not more than 24 clients can  associate with the AP because the throughput of the AP is reduced with  each client that associates to the AP.

    Please explain how one would accomplish that feat.
    There's not much to explain. When a device is connected, you see the row of different categories across the top: Summary, Info, Apps, Tones, Music, Movies, TV Shows, Podcasts, Books, and Photos. For example, it is perfectly safe to sync one iOS device to the Music category on Computer A and no other computer, and the same device to Photos on Computer B and no other computer.
    You might be confusing what I'm saying with one iOS device enabling sync to the Music library on multiple computers. That is a huge no-no and will result in the disaster being suggested. But I am not talking about that, I'm talking about the opposite arrangement. What I am describing preserves category exclusivity. It turns out that exclusivity at the category level, not the computer level, is what really matters.
    As long as a device is synced to a given category on only one computer, it doesn't matter which computer it is or whether that computer is different than the ones synced to on other categories. The instant a given category is enabled for syncing on more than on computer, that is where the trouble starts.

    Trying to do so is asking for trouble. Don't do it. Move the content you need to one machine and sync only with that machine. If you don't, you'll be back here asking how to fix the mess and recover all the stuff you lost...
    I will agree that it is something you should only do mindfully. But if you do make sure each category is syncing to only one device, there will be no data loss and no mess.

  • How many pcs can wirelessly connect to an Officejet P1102w printer

    What limits how many separate PCs can connect to an Office Jet P1102w. Is there a limit in the printer or is the limit more likely to be in the router?

    Hi KiamaraKid,
    I understand you have a Laserjet P1102W printer and are wanting to know whether there is a limit on the printer as to how many computers can connect via network, or if the limitation would be on the router's end. I will do my best to help you with this issue.
    With our HP printers wireless performance depends on physical environment and distance from the access point (router). Wireless operations are compatible with 2.4 GHz routers only as well. So the short answer is that the limitation is mainly on the router.
    If you can get back to me with the router make and model, I will certainly see what I can find for you about it's limitations (meaning, how many computers can connect successfully to the router and thus the printer).
    Hope this helps! Have a great day!

  • How many devices can I connect to my HH2

    It seems that no devices can connect to my Home hub 2. Is there a limit to how many I can have logged on? Quite a few of them are old comps and phones of guests, so can I just delete them, somehow, or even just reset the Home Hub, and reconnect with the devices that need it?
    Thanks!

    Assuming you are using it out of the box and haven't changed the DHCP settings there should be no limit unless you are trying to connect them all within 24 hours. Are you trying to connect using wireless or a cable?

  • How many devices can I connect over USB to Configurator simultaneously

    Hi,
    I am looking for confirmation (preferably from Apple!) as to how many iOS devices can be connected via USB to Configurator simultaneously?
    There is one document from Apple which states 30 devices is the limit but we use carts with many more than this which Configurator appears to handle fine. You can also buy carts which accept more than 30 devices from the Apple Education Store.
    What I really need is an official document stating the limit or some feedback from you guys on your experiences with Configurator and high numbers of devices!
    Any help would, of course, be appreciated
    Thanks.

    Depends on your USB hardware....I have had two Bretford 30 unit carts running and while slow will work...Actually in our last deployment I went back to one MacBook Air AC station per 30 cart (4-5 carts per building) as the timing worked out better with temp workers and workflow....

  • How many times can you connect ipad to a different computer?

    I have an Ipad 1 and when connecting it to my new laptop (not Mac) it told me the device could only be connected one more time to a different computer. Are there limits on Ipads as to how many computers or times we can connect them to? Is there any way to reset this or not?

    When it comes to apps, this is right, unless you use the Windows version of iFunBox (the Mac version, not even the latest version, doesn't work for direct IPA transfer). However, you can transfer / sync music / videos from several computers using third-party tools (without jailbreaking!!) with tools like SyncPod / FreeSync.
    You may want to read the section "A side remark: put music / videos / other media on your iDevice without iTunes" at http://www.iphonelife.com/blog/87/ios-contact-management-duplicate-removal-impor texport-etc-tips-and-tricks for more info.

  • How many people can't connect to other iSight users?

    Hi everyone,
    A few months ago, before Tiger and iChat 3.0, two members of my family and I noticed that we suddenly stopped being able to connect with each other using either video or audio chat. We all use iChat and all have iSights. Different macs. Same OS. Even after we all upgraded to iChat 3.0 we still get error messages like "insufficient bandwidth" and "user did not respond" even though we all use cable modems, no routers, and our firewalls are configured properly (even when turned off it doesn't matter). None of us are able to connect with each other, which would appear to eliminate the possibility of one malfunctioning computer. For months we have worked with the Apple tech guys to find an answer. They have told us in the past that they were aware of the problem and were working on a patch, but that was a long time ago and no patch materialized.
    Because tech support was unable to come up with a solution, we took our case up with upper level Apple management. We were recently told that no such problem has been brought to their attention, and if it did, it is likely the fault of misconfigured ISPs. How can that be? We use companies like Comcast and Time Warner, if it was a problem on their end wouldn't lots of people have complained? Even if it's true, what are we supposed to do about it? I'm starting to feel like we're being given the runaround and am getting close to demanding my money back on the three iSights we bought.
    I would like to know, how many other iSight users have encountered similar problems with connecting to other iSight users and been unable to fix them?
    Searching through this forum I have found a few postings from people who seem to have similar problems, but I'd like to confirm that we are not alone--and of course would love to know if anyone has found a solution!
    Thanks,
    Tony

    Ok:
    I do not post too frequently in this discussion group, but i have found at least one solution to the "Can't get video from the camera" error message in iChat after upgrading to Tiger 10.4.3. I have a feeling there may be several other types of errors that cause this problem but here is what ultimately worked.
    MY PROBLEM - computer seemed to work fine -- first noted problem was not being able to start either audio or video chat in iChat. It had work prior to upgrading to 10.4.3.
    Equipment:
    Titanium G4 powerbook 1Ghz; 100gig HD (6mo. new.) , 512 MB RAM, iSight, iChat 3.0, QT 7.0.3, Airport base station (not the Extreme) and there is an Airport Express in the house.
    FAILED ATTEMPTS TO FIX:
    Tried to perform basic repairs. Repairing permissions seemed to work -but had no effect on problem, Combo Updater 10.4.3 installed smoothly - but had no effect on problem, reverting to QT 7.0.1 also installed smoothly, but had no effect. Running Disk Repair from the OS X CD should "INVALID KEY ERRORS" UNABLE TO REPAIR DISK. Also, computer failed to boot in safe mode.
    HERE IS THE WHAT WORKED: NO MORE "CAN"T GET VIDEO FROM THE CAMERA" ERRORS and iCHAT works fine, even with new QT 7.0.3 and ARD running.
    -Downloaded DISK WARRIOR 3.0.3
    -Installed on different MAC that was no having problem (it was running Panther.)
    -Plugged problem plagued mac into firewire port of second computer and started it up as a Firewire HD (hold "T" key while starting)
    -Ran Rebuild function on Disk warrior. A ton of disc problems were found and corrected. Some corrupted files were copied to a separate folder. Process took nearly an hour.
    -replaced and saved new directory information.
    -Shutdown problem computer (just press the power key)
    -unplug the firewire cable connecting the two computers.
    -restart problem computer.
    -After booting up - run Disk utility and repair permissions.
    -Restart
    -after booting - run sooftware update - It should ask you to Reinstall QT 7.0.3 -- go ahead and do this.
    - Restart after installation finishes.
    - Run repair permissions again.
    - Check that you are runninig both 10.4.3 and QT 7.0.3.
    -Start iChat.
    I have a feeling that most of these problems with iChat are being caused by plist corruptions and errors that occur during software updates. So not every one will have the exact same problem but I suspect most problems will be fixed by repairing the drive and the permissions.
    Hope this helps
    Bryan
