Make a test with thin client

Hi all,
I'm facing a strange boring problem. I've a tomcat runs a webapp that using thin client connects to a remote DB.
From about a week is not able to connect anymore. Java hangs and report this error:
java.sql.SQLException: Io exception: Connection reset
So I've no firewall and listener is correctly working. Telnet to listener is working.
Does anyone has a simple java class to run to make a connection test?
Thanks
Stefano

Use preparedStatement either like this
String query = update tableName set datefield= TO_DATE(?, 'YYYY-MM-DD HH24:MI') where id= ? ";
and setString(1, string);
or
String query = "update tableName set datefield= ? where id= ?";
and setTimestamp() or setDate () depends what you need in your date field .

  • HPDM using WOL with thin clients using WES8

    When using HPDM 4.6 with t620 clients using WES8, the Wake on LAN option does not work.It makes it impossible to do settings and deployments outside office hours.How can this be fixed?

    Hi,
    Thin clients normally have a low memory allocation on the video card (8mb to 16MB) so this can be a problem.  Check to see if you can change this in the BIOS on the WYSE.  If not connect at 256 Colours to reduce this.  If you have pictures linked to products then their resolution will not be good but for SAP itself the difference is small.  Also rename the SAPSS.AVI to .old if you have not already done so so that the splash screen does not come up when logging in.
    In my multimedia testing on thin clients, unrelated to SBO, I found that both memory and processor power made a huge difference, which is contrary to thin client manufacturer claims.  As an example I used a 200MHz/64MB TC for a flash application and sound was about 3 seconds behind the image and the image update would skip 3 to 5 frames when updating.  Moving to a 800Mhz/128MB TC The frame refresh rate was almost perfect and the sound was only about 0.5 seconds behind.  I would therefore test on a more powerful thin client to see if it improves performance.
    The S30 is a 400MHz (rated @ 533 on performance by AMD).   Try a 1GHz TC with the maximum Video memory you can find.
    We are currently using VXL Itona 800Mhz/128MB and do not experience too much rolling but we are using 256 colours.
    Hope this helps.

    Place some debugging code and see if URL is null. Also, although it is nice practice, you don't need to catch every type of exception. Try (no pun intended):
    catch (Exception e) {
    System.err.println(e.getClass().getName() + ":" + e.getMessage());

  • Mac Pro with thin clients

    Hello,
    I am looking for a configuration of a Mac Pro server with thin clients so that software and data is centralized on one location.
    Is that possible with Mac OS X ? And does Apple have thin clients ?

    I have the same question. I am about to buy a Mac Mini with Leopard server, if I can connect thin clients to it. I have good old PCs with Win and Linux, I want to use them as thin clients

  • Can I run ADF BC tester as thin client using embedded Tomcat or Websphere?

    Hi folks,
    I fired up JDev and ADF BC after a long hiatus and was pleased to find my old friend, the appmodule tester. I will probably be demo'ing the tester tomorrow at my new job.
    I would like to show the AppModule tester as a thin client application that dynamically browses appmodules, viewobjects, etc in the same way that the 'fat client' tester works.
    I poked around some but haven't found anything. Can someone chime in?
    Thanks,
    Andrew Wolfe

    Nothing automatic - but it is quite simple to just create a JSF page and drag the ADF BC view objects from the data control onto the page - drop as Form - or as master detail and get the functionality working.
    Then you just press run on the page and the integrated WebLogic Server starts your page in a browser.
    See this for example:

  • Cx_Oracle dosen't work with Thin Client

    Is there an alternative to the Fat- & Thin-Client installation to get cx_Oracle running.
    I would like to tell my custommersomething like "install Addon XY in addition to the Thin-Client akording to the Oracle Vresion you are using."
    I Know of the possibility to enhance a Thin-Clinet installation by copying certain files and folders from the server.
    But our Application should work for manny custommers, with different Oracle-Versions. And we just can't expect a DBA
    to let him do all needed Steps to get cx_oracle running.
    Anny Idea?
    Thanks

    AFAIK with the same cx_Oracle's source code you can build versions for different oracle's clients (at least in my experience it always asked me my $ORACLE_HOME and $LD_LIBRARY_PATH and the setup.py handles different oracle's version). It might work with 9i, 10g and 11g (I wouldn't risk to talk about 8i).
    Besides that Oracle instant client is free to distribute (see here) so you can bundle it with your code. I can imagine it would be pretty easy to build it in *unix although I'm not sure bout Windows -for lack of experience with that particular OS-.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

  • PEMInputStream with thin client

    I am trying to get around using the weblogic.jar for my Weblogic client. I would
    like to use the
    wljmsclient.jar and wlclient.jar in order to make my client carry less weight.
    However, I need to
    use the PEMInputStream in order to perform my 2 way SSL. The only place that
    I've seen this
    PEMInputStream class is in the big, bulky jar. Does anyone have any suggestions?
    Thanks in advance,

  • Which would be the best NAC approach with thin clients up today?

  • Having trouble with thin client

    Hello all,
    First of all, I appologize if I post in the wrong section. So please, just move it where suitable.
    I have HP T5000 Thin Client and I would like to connect it to a desktop computer that runs Windows Multipoint Server 2012. My problem is that it doesn't accept IP address sent by router. If I enter parameters manualy, it still can't see other computers in network. Does this mean that something failed or that I have to setup something else.
    Also, would you be so kind as to suggest what would be the best option for this device - which server to connect it to and in what way?
    Thank you very much in advance.

  • Using SBO with Wyse Winterm S30 Thin Clients

    I have a customer who is using Microsoft Terminal Services via Wyse Winterm S30 Thin cllents to access SBO over a VPN.  We are experiencing excessive rolling (redisplay) when screens are refreshed. The problem is compounded if a Marketing Document contains multiple Text lines. We have two terminal servers, each with about 12 thin clients connected.
    I would appreciate feedback from anyone with experience of using thin clients, regardless of brand.

  • RemoteApp on Thin Client

    Hi all,
    Newbie question I'm afraid....
    I have an application that I wish to host on a Server running 2012r2 with RDS and run on either a thin client or a touchscreen device running a thin client.
    I only wish to run this one application and so my question is this:
    Can I create a remoteapp and have the thin client run that without any desktop or do I have to use a virtual desktop
    and autorun the application?
    Any recommendations appreciated,
    Thanks
    Rich

    Hi Rich,
    Thank you for posting in Windows Server Forum.
    Yeah, nowadays RemoteApp is the best way to provide application access to user. But to access RemoteApp we need to run RD Web sites such as
    https://rds.com/rdweb. So if you want to access RemoteApp from any of the device you need to access RDWeb sites. So for thin client you can access RemoteApp directly on thin client without installing Virtual machine. Just make sure that you need to
    make correct configuration under thin client by providing terminal server name and RD web URL and so on. For your guidance you can refer
    this video.
    Hope it helps!
    Thanks.

  • HPDM 4.6 vs. Thin Client Out of Network

    I just finished setting up and testing a thin client at my house, connecting back to the HP Gateway/Server in the office.  With enabling port forwarding, and configuring the HPDM Agent on the thin client, everything is working great, except for one thing...  Any task I send to the thin client goes to "Sending" status , and then it will sit there until the thin client is rebooted manually.  Once the thin client boots back to where it was, the task that was sent executes successfully.  This includes Shadowing, Renaming, Changing Time/Screensave settings, etc. Can someone point me in whatever direction is necessary to change this behavior?  I'm thrilled that it's working at all, except for requiring a reboot for every single task. Thanks in advance!

    Hi, Could you please shorten the "pull interval" on the client side? You can change it through "Agent Configuration" UI on the clide side. Based on your description, your tested thinclient is behind NAT relative to DM gateway.  In this case, every tasks send to DM gateway cannot be sent to DM agent directly. The task will wait until DM agent get it actively. Pull Interval is the parameter to trigger the "PULL" task from DM gateway, it was set to 1 day by default which means agent will pull task from Gateway for only once every day. Restart the agent is another way to trigger the "pull" action, that why your task works after reboot the client.
