Close TCP leaves the connection open

• TCP/IP, the connection lost?

  I'm talking with a supply of California Instruments MX15 using the TCP/IP protocol. I downloaded their GUI to control the power supply remote so I could familiarize myself with its operation. The user interface works fine without any connection problem. I'm now trying to make my own driver (the driver download that they provide on their site does not work) to control remote electric power. I have attached the VI that I try to send just the * IDN? command and query an answer back. If I can get this working, I have no problem to find the rest. However I tried to figure this out for the last day or two and nothing helped. I'm new to TCP/IP, but now I understand the bases because of all my google work many hours:

  I have attached my VI to watch. As you can see I tried to use the VISA function as well as the TCP service. The TCP function works fine without error returned, but returns nothing in the buffer and expires. The VISA function however opens communications on the electric network but when I try to send a command to the power it gives me this error:

  Error 1073807194 has occurred at an unidentified place

  Possible reasons:

  VISA: (Hex 0xBFFF00A6) the connection of the given session has been lost.

  Any help is appreciated, thanks in advance.

  You send a character of endpoint with MAX, but not in your VI. Don't forget to click with the right button on the constant and activate '-' code display.

  VISA server isn't essential.

  You mean that other users do not have their own user accounts?
  They all connect to your own account?

  If they all have their own user account to log on, they can't see your personal files, unless...
  1. your files in public folders.
  2. they have your password to login to your own account.

  So, please clarify.

• Leave the connection due to release/renew IP address problem

  Hi there - I have an Inspiron 23 model 5348, connected to a router of the BT Home Hub 5 running Windows 8.1. Whenever I wake the computer from sleep mode and often even to start it upward, that I have no internet connection. I have release/renew the IP address, and the connection is re-established for a period of time.

  This happens on my inspiron wired or wireless connected. I updated the router, changed the wires, reinstalled the drivers for network devices, changed the term of the lease on the router for 21 days and used a static IP address, bit, nothing seems to work.

  It only occurs on the Inspiron. None of my other devices give up their connection.

  Any ideas what is the cause?

• Keyboard does not close and loses the connection.

  Hi guys,.

  Having a problem at the time with input boxes and the keyboard to phonegap. the issue appears only on apple devices. It is very well on Android. We get an application of simple connection with two input fields:

  

  Now, when we enter a correct user name and password, the keyboard disappears and the app moves on. The quirk seems to be when using incorrect credentials. The keyboard stays on the screen and the cursor remains in the last box you typed in. However, by pressing the keys on the keyboard has no effect on the box. By selecting other credentials of entry also has the same effect. You must close the manually close the keyboard and press again on one of the boxes.

  I have tested on several iPhones and iPads with the same effect. When I run the site directly into a browser rather than through phonegap, it works as expected; The keyboard closes and an error message is displayed. I tried calling blur() on entry on touchstart and touchstart event fields and tried focusing on the button "login" during the presentation, but they seem to have no effect.

  Anyone seen this before? If you need more info let me know.

  Thank you

  James

  I have to guess here:

  -It really has nothing to do with the "evil powers". It's how you manage the entry that does not have the keyboard disappear (again)

  -a page switch, the keyboard will disappear

  -I guess the keyboard also disappears when the form is submitted, but not (yet) on the touchstart event

  Then; I suggest catch you to the event of the form, then use ajax to send data to the server.

• Y560P card number: sleep mode and headset to the connected socket

  I searched the forum as much as I could and did not find this issue to be considered.

  So, sometimes I listen to music with headphones or even after a Skype call, I leave the connected headphones. If I put the laptop to sleep and wake it back up, unplug the headphones will not return my sound setting to speakers; I can't hear any sound if I plug the headphones in the back.

  I tried to connect and the new: no change. I tried to disable and re-enable "Realtek High Definition Audio" in the Device Manager: no change. Uninstall and reinstall it wouldn't be a good solution if it had to be done all the time. The only thing that it returns to normal is turning works again... typical I.T. solution. Is there a driver update to solve this problem?

  Speaking of driver updates, I guess that I can't find any BIOS update or updates to driver for the ideaPad due to the recall of Sandy Bridge?

• 63 error to TCP connection open in Simple data Client.vi when connecting to the network storage device.

  Hello

  I tried the simple data client and simple example of data server. I tried this example to connect to a NAS device. My laptop properly communicates with the device since I ping the address of the NAS device and discovered it works perfectly fine. Also, I put the static IP of my pc even as the NAS. So everything I've done. But when I run the program giving the ip address of a NAS device, it shows an error 63.

  Error 63 to TCP connection open in Simple data Client.vi

  Possible reasons: LabVIEW: serial port receive buffer overflow. = LabVIEW: the network connection was refused by the server.

  Why is happening. What can be done to solve this problem. Thanking you.

  What is the firewall of the SIN.

  Yes, it is very likely. Try disabling the firewall and try again. If the code works when you run the Server & client on your machine, but not when you run the server on your NAS and client on your machine (assuming you have entered the correct port for the NAS server), then it is very likely to be a firewall problem.

  vindsan wrote:

  Server that is listening is no longer VI also means what.

  Your VI server listens only once for a connection after receiving an incoming connection (or it expires after 60 years), he stops listening and the port will be more open for incoming connections - you must re - run the VI for another connection. With your code, you must run the VI server and then run the VI client in the 1960s, so it's not expire.

• Open and close the connection in oracle procedure

  Here is the procedure I'm in I insert data into the table temp_soap_monitoring using the select statement. I have soap_monitoring table FONIC_RETAIL database where I want to take the data and insert into the table temp_soap_monitoring. I play the position of planner of all 5 minutes for this procedure so that I get always the latest data in soap_monitoring@fonic_retail table. The problem of this procedure is that it takes too much cost and the query execution time to perform this procedure. Whenever he tries to extract the data from db link and save my local database. I remember in Java, php, and other programming languages, we have method in order to open the db connection when we tried to extract data from db link and then once integration is complete, we can close the db connection. So the performance improves and also has no load on db link. In this method, we have to assign link db to retrieve the data. So I think is it possible to apply this logic in my oracle procedure. The question arises because at this moment I am hard code the link db, but now I have 3 db more links and I will not reproduce the same procedure by assigning diffferent db links.

  PROCEDURE  "EXT_SOAP_MONITORING" AS

LAST_SM_ID Number := 0;
LAST_CAPT_DATE DATE;

BEGIN

SELECT LAST_TASK_ID INTO LAST_SM_ID FROM CAPTURING where DB_TABLE='TEMP_SOAP_MONITORING';

insert into TEMP_SOAP_MONITORING(ID,REQUEST_XML,RESPONSE_XML,WEB_SERVICE_NAME,WEB_METHOD_NAME,CREATE_DATE,ERROR_CODE,ERROR_MESSAGE)
select ID,REQUEST_XML,RESPONSE_XML,WEB_SERVICE_NAME,WEB_METHOD_NAME,CREATE_DATE,ERROR_CODE,ERROR_MESSAGE from
SOAP_MONITORING@FONIC_RETAIL WHERE WEB_SERVICE_NAME ='RatorWebShopService'  and WEB_METHOD_NAME = 'placeShopOrder' and ID > LAST_SM_ID order by ID desc;

update
CAPTURING set LAST_TASK_ID=
CASE WHEN ((SELECT MAX(ID) from TEMP_SOAP_MONITORING) IS NULL) AND (LAST_TASK_ID  IS NULL)  THEN (SELECT MAX(ID) from SOAP_MONITORING@FONIC_RETAIL)
WHEN (SELECT MAX(ID) from TEMP_SOAP_MONITORING) IS NULL THEN LAST_TASK_ID + 1
ELSE (SELECT MAX(ID) from TEMP_SOAP_MONITORING) END,
CAPTURING_DATE = CURRENT_TIMESTAMP, LAST_CAPTURED_DATE = LAST_CAPT_DATE where DB_TABLE='TEMP_SOAP_MONITORING';

END EXT_SOAP_MONITORING;

  I have it here is the procedure which I insert data in

  temp_soap_monitoring table by using the select statement. I have

  soap_monitoring table of FONIC_RETAIL database where I want to take the data and insert into the table temp_soap_monitoring.

  WHY? Why you are moving the data? Why not just use it table, is it already?

  The problem of this procedure is that it takes too much cost and the query execution time to perform this procedure.

  The solution is to FIND THE PROBLEM. Troubleshoot the code and find out where is the problem, if any.

  Based SOLELY on what you have posted the solution might be to add just an appropriate index.

  What? The LAST thing you want to do is keep the closing and opening of the connections. I don't know how 'remember you' from Java or other languages. The main reasons pools of connections were invented to AVOID have to repeatedly open and close connections.

  A db link not a NOT a "charge" - the "charge" is the query is made. If you write a poor query or have a poor data without the necessary index model, or have missing statistics, then you will get poor results.

  In this method, we have to assign link db to retrieve the data. So I have

  You can certainly write Java code to connect to each database with a direct connection. But all write code PL/SQL must include the database link. And the only way to avoid hard-coding the link is to keep the names of link in a table and use dynamic sql statements to build and run the query. This isn't what you want to do if you're looking for performance.

  SELECT LAST_TASK_ID INTO LAST_SM_ID FROM CAPTURING where DB_TABLE='TEMP_SOAP_MONITORING';

  For all we know which could be the WHOLE CAUSE of your problem. If there is no index on the table, you could do a full table to a table with lines scan 800 billion;

  We have NO WAY of knowing since you haven't posted info. Please read the faq to find out how to post a request for tuning and the info you provide.

  1. the query

  2. the table and index DDL

  3. the execution plan

  4 RowCounts for tables and query predicates

  5. the info on the stats: how you collected them and if they are up to date

  update
CAPTURING set LAST_TASK_ID=
CASE WHEN ((SELECT MAX(ID) from TEMP_SOAP_MONITORING) IS NULL) AND (LAST_TASK_ID  IS NULL)  THEN (SELECT MAX(ID) from SOAP_MONITORING@FONIC_RETAIL)
WHEN (SELECT MAX(ID) from TEMP_SOAP_MONITORING) IS NULL THEN LAST_TASK_ID + 1
ELSE (SELECT MAX(ID) from TEMP_SOAP_MONITORING) END,
CAPTURING_DATE = CURRENT_TIMESTAMP, LAST_CAPTURED_DATE = LAST_CAPT_DATE where DB_TABLE='TEMP_SOAP_MONITORING';

  My guess is that TERRIBLE method of trying to get a 'LAST ID' is what's causing ALL your problems of performance. This method will not scale, and it will NOT properly work in a multiuser environment.

  You need create a good BATCH_CONTROL table that all processes use during the creation and execution of lots.

  The MASTER of the process batch:

  1 Gets a new BATCH_ID using a sequence

  2 locks the current row in the table control and uses / change the value "last".

  3 creates a new line in the control table for the new batch process

  4. the line of control to date with the start time, end time, result State, County, etc. for the batch

  Your likely PROBLEM of has NOTHING to do with the links of the db.
