To keep active or not? There is the question.

Hello

I have a small question of design for you...

I have a server periodically communicates with multiple devices (1-30). The communication is made by TCP - IP and data are sent periodically (every 20 seconds for example, can be less or more).

Wouldn't be better to keep my active connections all the time (in hours or days) or close and reopen a new connection whenever I want to send some data?

Thanks in advance!

Vincent

If the application is going to be up and running forever, so I would design for open it once and keep it open. If you encounter errors close to the former and re - open a new connection. In order to keep the "open" to a minimum.

If the application will simply to run for an hour or two, then it is a toss-up.

Reasoning above:

Whenever a resource is affected by BT a small block of memory is resereved for managing modes kernal (?) stuff. This block of memory is never communicated until LV is running. If you open several times a ref, you will slowly be memory leak. You can prove to yourself in crates a VI that opens a farm a reference several times in a loop and let it run for the weekend. If you find the use of the memory before and after, you should be able to Messure the leak. Over time, he will eat all of the available memory.

Just trying to help,

Ben

  • Default method of workflow activity is not called when the Page refreshes

    Basically, try to call a script function java front page of fragments of the charges.

    INSTALLATION PROGRAM:

    Jdev 12 c

    TF defined with a default activity that invokes a page fragment.

    The activity of default method calls a method to support bean which inturn calls the method init java script before the fragment on the page doesn't load.

    This TF is in a container jsf page.

    During the loading of the page containing the first activity of the method is called and js function triggers and then fragments of charges which is the desired behavior.

    PROBLEM:

    When I refresh the page by pressing F5 or by running the page again on the same window of the browser activity method default IS NOT gets called which inturn will not trigger the js call.

    But when I run the same page again in a different window it works and then subsequent updates or page load activity IS NOT of default method is called.

    If it is not provided? The default activity is called when the workflow is updated.

  • for bitmap or not, that is the question

    Hello my friends tuning.

    I'm running Oracle 11.2 (on Solaris 10) for a database very active OLTP, but which is also frequently used to pull reports on the more volatile critical table in the database.

    My database has anywhere from 100 to 400 concurrent users.
    Our application (REMEDY) is designed to put 'tickets' in one main table (with about 560 fields that 40 are CLOB).
    The dilemma, I need help is if we put a little map on some low cardinality columns indexes or not.
    And, besides, the number of columns in this table is very low cardinality.
    My fear is that I fear that putting a bitmap on a highly active OLTP table index might decrease the performance of ticket creations (new lines in the table).
    Can or, if I did, I have a job done every night that re-creates the index bitmap on this table?
    But what about performance on the table between the time to rebuild the indexes of BM?

    In this case, it is a query that is run on our main table (containing the records of about 6 m and is 16G in size).
    When I look in OEM, I see that he did a scan of full table on this table and in this case, returns only the records of 262.
    Of course, you can deduce that the columns in the predicate clause are very low cardinality (by the names of the columns and the values you want).
    SELECT "Main_Ticket"."SHORTTICKETNUMBER"      ,
        "Main_Ticket"."OUTAGESEVERITY"        ,
        "Main_Ticket"."OUTAGESEVERITYTEXT"    ,
        "Main_Ticket"."OUTAGESERVICESLIST"    ,
        "Main_Ticket"."OUTAGESTATUS"          ,
        "Main_Ticket"."OUTAGEOVERALLSTARTTIME",
        "Main_Ticket"."OUTAGEOVERALLENDTIME"  ,
        "Main_Ticket"."CITY"                  ,
        "Main_Ticket"."STATE"                 ,
        "Main_Ticket"."MASTEROUTAGE"          ,
        "Main_Ticket"."GROUPCREATEDBY"        ,
        "Main_Ticket"."GROUPASSIGNEDTO"
FROM "ARADMIN"."MAIN_TICKET" "Main_Ticket"
WHERE "Main_Ticket"."OUTAGESEVERITY"<=2
        AND NOT
        (
                "Main_Ticket"."GROUPASSIGNEDTO" LIKE 'BBSG%'
                OR "Main_Ticket"."GROUPASSIGNEDTO" LIKE 'CIA%'
                OR "Main_Ticket"."GROUPASSIGNEDTO" LIKE 'DESIGNED%'
                OR "Main_Ticket"."GROUPASSIGNEDTO" LIKE 'IHD%'
                OR "Main_Ticket"."GROUPASSIGNEDTO" LIKE 'NABB%'
                OR "Main_Ticket"."GROUPASSIGNEDTO" LIKE 'NCC%'
                OR "Main_Ticket"."GROUPASSIGNEDTO" LIKE 'NFC%'
        )
    I guess that put the index bitmap on 'OUTAGESEVERITY '.
    Not sure about the GROUPASSIGNEDTO, because it uses the SIMILAR function and may not use the index BM if she had a.
    In this case, an FBI would be better?

    put a bitmap on a table with DML heavy index looks like a very bad idea and I would not even sure if it would help your request (which is the number of values<=2 compared="" to="" the="" total="" number="" of="" rows?="" -="" if="" this="" is="" a="" significant="" amount,="" then="" a="" full="" scan="" is="" propably="" in="" order="" anyway.).="" put="" an="" fbi="" on="" the="" text="" column="" is="" also="" not="" very="" likely="" to="" help="" you="" out,="" especially="" with="" the="" not="" clause.="" it="" would="" be="" much="" easier="" to="" reverse="" the="" logic="" here="" like="" ...="" and="" groupassignedto="" in="" ('group1',="" 'group2'...)="" as="" long="" as="" the="" number="" of="" different="" values="" can="" be="">

    In general, how do you the idea to keep a second copy of this table for reporting? You can create a view, materialized from this table and then create your index bitmap on this MV and run your reports against it. Maybe you could get away with just a drink a day? And the strengthening of this way that you will not lose DML performance against the table real all performance reports. Just an idea

    It seems that your Tomcat missing the JTA parameter.

    Tomcat

    To use LiveCycle Data Services with Tomcat when not to use the integrated Tomcat configuration, install support for the Java API of the Transaction (JTA). You will also need to install several other libraries depending on the features you want to use. Follow these steps after deploying the LiveCycle Data Services WAR files. These steps are not required for the integrated Tomcat installation.

    1. Stop Tomcat.
    2. To install support for JTA, a recommended implementation is the Manager of operation open Java (JOTM), which is a transaction manager standalone fully functional opensource.
      1. Download JOTM from http://jotm.objectweb.org.
      2. Copy the JAR files from jotm -root/lib to [tomcat root] / common/lib.
      3. Create a context for your web application and register JOTM using the Transaction element. For example, for the samples WAR create a tomcat-root/conf/Catalina/localhost/lcds-samples.xml file and add the following lines:
        CONTEXT antijarlocking="false" antiresourcelocking="false"   docbase="${catalina.home}/webapps/lcds-samples" path="/lcds-samples"   privileged="true">

        Note: If a context file exists for your web application, add the element under the element.

    3. Increase the maximum memory to at least 512 MB by specifying the maximum segment size for the JVM in the JAVA_OPTS:-Xmx512m
    4. (Optional) To enable custom authentication, locate libraries under install_root/resources/security/tomcat Tomcat security resources.
      1. Place the fichiers.jar - tomcat-flex and flex-tomcat - server.jar in tomcat/lib folder.
      2. Add the following line in the file descriptor context for your web application:

        You can now perform authentication against the current Tomcat realm. Generally, the default configuration for authentication stores information user in conf/tomcat - users.xml. See the Tomcat documentation for more information on realms. See the LiveCycle Data Services documentation for more information on custom authentication.

      3. You may also update her active > in /WEB-INF/flex/services-config.xml in each deployment of a LiveCycle Data Services WAR file. For Tomcat, ensure that the TomcatLoginCommand is active in the section:
        ...
    5. (Optional) To use the JMSAdapter with the Message Service, install and configure a JMS (such as ActiveMQ or openJMS) for use with Tomcat.
    6. Restart Tomcat.

  • My external hard drive will not go up and I'm not sure what the question is

    My external hard drive will show up in disk utility, but not of viewfinder. I tried to hit "repair disk" and he says it will take 4 hours, but after a while, that he's finally going to say that it is impossible to repair the disk and I need to make a backup.

    Almost always, the question is quite simple: the hard drive is faulty or has failed. So I hope that you have a backup of everything that is on, it is absolutely essential.

    The type of key and partial media product indicates that you have used a reinstall drive (or other media) that was produced by Dell for a Dell computer.  Your motherboard reports himself can be made by Gigabyte Technology, (which would not arise a Dell system).  The BIOS does not have the required for activation OEM SLIC input.

    You must change the key non - SLP product key, as in a detail (product complete package), selling retail or OEM system builder version of Windows 7 upgrade.  for example the COA/sticky label that came with the computer or the installation media of Windows 7 and then try to activate online or by phone.

    If you used a modded BIOS of third party who attempted to add the string SLIC 2.1 for a motherboard that is not made by a royalty OEM (which Microsoft believes that a form of hacking), then the BIOS mod has not done correctly.

  • WLC 5 GHz active SSID not visible in the available networks

    We use WLC 2504 with 2 AIR-CAP2702I-D-K9Access Points. I am facing a problem of slow performance with customers active wifi (Macbook Pro). As all the clients that we use are computers laptops Macbook Pro who takes supported 802.11ac, I created a new WLAN (SSID) with Radio 802 11 a only to force all laptops to use the 5 Ghz band to check that it makes the difference. The SSID is not visible as a network available on the client if the radio SSID is set to "802. 11 a only"if it is marked to broadcast the ssid. '802.11ac' is also enabled in the network "802.11a/n/ac" categories of wireless.

    That means my Access Points do not support the 802.11ac?

    Yes, the Country is set to US which is not correct, Does it make any difference?
    As Leo does, that's the problem. Configure the appropriate country code where this access point works (appropriately by the detail of the AP, India). See below http://www.cisco.com/c/en/us/products/collateral/wireless/access-points/product_data_sheet0900aecd80537b6a.html see this post to see how you can configure https://mrncciew.com/2013/04/07/configuring-country-codes-on-wlc/ HTH Rasika * Pls note all useful responses *.

    Bookmarks toolbar no longer works. I can still access my favorites, just the toolbar will not appear even after checking and unchecking "view bookmarks toolbar".

    Bookmarks toolbar no longer works. I can still access my favorites, just the toolbar will not appear even after checking and unchecking "view bookmarks toolbar".

    OK I thought about it. My browser is a mode full screen to the value by default after the update, and for some reason bookmarks toolbar does not appear mode full screen. So when is out of full-screen, the toolbar appeared.

  • Sub - Entered VI buttons activation do not Structure of the event

    Hey everybody,

    I have anissue with a Subvi, which takes a user file, play with the type of path of file data until it is in the form of a string, and then puts it in an array of strings in a list box. The issue I'm having is that I created the entries and exits to the buttons in the image, but the case event structures they control are not running when I press the buttons that are connected to the terminals of the Sub VI (the buttons move up one level in the image below).  They DO not work when I use the Panel front of the Subvi rather than on the front of the VI Panel that comes up to the next level.

    So far I have tried:

    -Move the buttons in the while loop

    -Move the buttons in the structure of the event

    -Case change event handling to run on a mouse click of the button from a change in value

    Thanks in advance for any help anyone is able to give me!

    Yes, writing a value to a Terminal never causes a value change event.  Think of it as an event "user has changed the value.  To trigger an event value programmatically, you must write to the Value property (Signaling) of the command or the change indicator.

    Values Boolean locking belong in cases that handles the VC event.

    You could read the terminal (use a local variable) before the time compare loop to the last value (use a feedback node) and use a case structure to determine if you want the event to VC based on the value passed in the appellant.

  • I was installing updates for Window7, the Internet explorerer and Startup icons, ect were not there when the computer reboots.

    I have Windows 7-64 bit. My resolution of the Office has also been affected, the bar downstairs is gone and all access to the computer control panel... Does that mean I need to restore or remove facilities? If so, how?

    Reboot it again and see if the problem goes away.

    Sometimes a 2nd reboot solves the problem, sometimes not.
