How many recordstore connections can be kept open

Hi all,
i have created a J2ME midp2.0 based application,
it requires to do database operations, for performance i want to keep recordstore open for frequently used record stores.( The open() close() on recordstore are expensive operations on some of the devices).
how safe is this, is there any threshold on number of recordstore i can keep open.
please advise

I would guess 2 billion (2^31-1.) That is because it probably has to keep track of something in java and that suggests an array. And that is the maximum size for an array.
Of course the actual number is going to be much less than that because it depends on the memory, cpu's, jdbc driver, database and licensing of the database. And probably other OS specific things like thread limits, file limits, resource limits, etc.

  • How many Voice connections can cisco 2821 support?

    Good day.
    I have a cisco 2821 with EVM slot, NME-X slot and two HWIC slots. I have 4 port FXOs on the two HWIC slots. The EM-HDA-8FXS module on the EVM slot can handle 8 FXS connections. Please i would like to know if there is an EVM module that can do FXO connections and also how many voice connections can this router handle in total. Can the EM-HDA-8FXS module handle both FXS and FXO connections?
    Hope someone can help me out. My deadline has already passed.

  • How many concurrent connections can ACS handle at once?

    Hi Experts,
    Could you please let me know how many concurrent connections ACS can handle at once?
    Is there any limitation on it?
    Our ACS version is 4.0 (1) build 27.
    Thanks in advance for your help and have a nice day!

    It depends on many other factors but as far as I know ACS can handle upto 40 Auth request per second*

  • How many voice messages can be stored on Skype?

    1. I wonder how many voice messages can be kept on Skype account?
    2. How long can be one voice message?

    You have to consider the comression though Ron, when you say that a nano will fit a thousand three min songs this is at a bitrate of 128kbs, with audiobooks you buy from say audible for example, they have four quality settings the highest being format 4 which encodes is 32kbps, this is fine for simple speech but would be terrible for music.
    So with this in mind such a low bitrate would use on average four times less space, so 50 would go way upto 200. But some of the books I listen to are upto 40 hours long!, anything as small as 3 hours would likely be a crappy abridged version which is no use to anyone.
    Also remember that you won't really need to keep more than 1 or 2 books on there at once, I mean why would you want to keep a whole library on there when they can just sit on your PC incase you ever want to listen to them more than once.
    Personally I use the highest bitrate possible for my audiobooks, such as 80 or 128, just depends what bitrate the file I have are in, I never need the space because I have few songs and only put one book on at a time.

  • How many concurrent connections that an ACS server version 4.2 latest patch can handle?

    I have about 50 routers and layer-3 switches that autheticate via tacacs+.  The AAA server used to be on a Linux machine running open-source tacacs+ built by me.  I have a perl script that will log into all 50 devices at the same time to collect statistics.  This script is multi-threaded.  Everything is working fine so far.
    I recently out-sourced the AAA function to a 3rd party company, not by my choice.  The 3rd party uses Cisco ACS version 4.2 with the latest patch running on Windows 2003 Enterprise Server with 16GB RAM and quad processors with quad-cores, IBM x3650-M2 hardware. The connectivity between the 3rd party and my company is through a DS-3 connection.  Maximum bandwidth over this DS-3 connection is less than 10Mbps at most.
    I noticed that for the past 3 months I have multiple failures with this perl script due to authentication failure with the ACS server.  If I just run the script again a few routers/switches, there are no issues; however, whenever I started the script to log into 50 devices all at the same time, it will fail.  If I made the configuration on all routers/switches to point back to the old open-source tacacs+ server, the issue goes away.  The minute I switched back to the
    new ACS server, the issue came back.  If I modified the script to hit one device at a time, it works fine.  I think it is the ACS server can not handle a lot
    of AAA requests at the same time.
    Does anyone know how many concurrent connections that an ACS 4.2, with latest patches on Windows 2003 Enterprise Server with lot of memory and CPU power, can handle?  I can't seem to find this anywhere on Cisco website.
    Thanks in advance.

    No, Im not saying ACS cannot cope.
    Concurrency and latency are very different things. ACS CSTacacs can handle many 100s of simple authentications/authorisations per second with users in the internal database. If 1000s of devices all send traffic in the same instant it would take some seconds to work through the backlog of traffic.
    Also, worth considering that a limited number of tasks within ACS (or threads) can actually handle a much greater number of "logins" because they are generally multi-message allowing ACS to keep lots of plates spinning.
    If users are in an external databases the latency (per authentication) can increase depending on where the users are (eg Windows AD) and if bad enough can have a serious effect on the overall authentication rate. At which point customers normally turn to load balancing.
    If your device timeouts are 20 seconds (totally reasonable) I suggest the issue is more likely to be something else... a bug, perhaps specific to v4.2?

    how many apple tv can I connect with one account?

    there are 2 recent posts that suggest issues over 5, one where someone was trying to troubleshoot for a friend or client as they couldn't keep more than 5 connected, and the other where somone had more than 5 but was using 2 separate itunes libraries to share the load - not sure if that was with the same or differing AppleIDs.
    I guess there is always the possibility that things kight vary from one itunes version to the next even unintentionally to allow more.

    I've read so many answers to these questions that, i don't really know what is the correct one. So, i would like to know what do you have. Here they are:
    1- How many max connections per torrent do you have set up?
    2- How many max opened connections do you have in mldonkey (or similar)?
    Last edited by dienadel (2007-03-08 08:25:36)

    AFAIK it's arround (total connections):
    - <5 for RTC
    - <100 for slow ADSL
    - <500 for medium ADSL
    - ~1000 for high-speed ADSL (and max on Windows lol) ; went up to over 1500, without positive change.
    I use rtorrent & have a limit of <100 connections per torrent (4 leechers max per torrent so they get something)

  • HT4941 how many mac mini can you connect to a thunder bolt display

    how many mac minis can you you connect to a thunder bolt display and if so how do you switch between them

    Here's the official page on connection options (you can connect one computer to a display).
    I've read elsewhere that you can connect two computers to the Thunderbolt Display, but you can't switch between them per se.  You can only power up one at a time.  Anyone, feel free to correct me on this, but my understanding is this is not an officially supported configuration.

  • How many apple tvs can i run at once

    i want to set up a trade show booth with apple tvs and a mac mini. how many apple tvs can i run off a mac mini? i want to run different slideshows.

    Pretty sure that one device (the mini) will only be able to interact with one Apple TV.  At best you might be abel to connect to multiple ATVs but they would all run the same content. (and I have my doubts about that)
    You can use the mini and multiple Apple TV's to watch different content, indeed you can only watch different content although you can listen to the same content. For the avoidance of doubt different includes the same content but not in sync.

  • At max how many logical columns can be created in RPD

    Hi All,
    At max how many logical columns can be created in RPD. I have a requirement of creating 200 columns. Will there be any problem .
    Is there any predefind number of columns for RPD creation??
    Please help ..

    Hi Annapurna,
    There's no limit that I'm aware of or which is mentioned anywhere. Just as an example: I have a logical fact table with around 750 logical columns (>500 original measures & 250 derived measures). No issue whatsoever. Opening the presentation table through answers takes about 2-3 seconds (the NQSQL command has a lot to retrieve), but that's about it.
