• ColdFusion 9 MySQL communication link failure

  just install Coldfusion 9 and everything now works fine and it is connected to my MySQL database via the administrator Coldfusion as a datasrouce, but I get this error that occur rarely, maybe 5 - 10 times a day. I don't know how to recreate it, and if you get it and refresh the page, it's gone.

  Error Executing Database Query. Communications link failure Last packet sent to the server was 0 ms ago
  

  The error is caught by coldfusion as it is displayed a friendly message and emailing me the problem.

  Most of the time loading pages and work fine and this problem occurred only since going from CFMX7 to CF9, both using MySQL.

  I use MySQL version is "5.0.77.

  I tried localhost and 127.0.0.1 as host in the source of data, it makes no difference.

  Does anyone have an idea what it is and how to fix it? I've seen a few similar posts for Java, but I don't see how to translate the fix everywhere in Coldfusion?

  And would that be a problem of MySQL or Apache anyway?

  The parameter keep connections means that after you create a db connection

  for a database, this connection will be used for the current request and

  then kept open in a connection pool so that they can be reused for later

  queries. The reason is that opening a connection is expensive once,

  consumption of operation and effective to have only authenticate

  once.  When this setting is disabled, each page request to access a

  given the database, a new database connection will be created, the db

  authentication will occur, that the query/queries on the request will happen,

  then the db connection will be closed.

  When you manage connections you have a db connection pool that may exist

  for an extended period, be reused frequently with additional requests.

  If the connections are inactive for a period over the idle time-out

  adjustment in the definition of data source connections are closed and

  the size of the pool is reduced.  Also, if a query retrieves a connection of

  the pool, trying to use it for a query to a query, then if cela db

  connection generates an error in the db, then that is another situation where the db

  connection will be closed and removed from the pool.

  He has been known to happen when you are pooling of data source connections

  the same as its possible that the TCP connection to the database has been

  interrupted for a reason, and when the connection is checked for use

  on a page request, you will get an error type of 'communication '.  The

  real error message will vary depending on the database.

  If resolve connections uncheck maintain this link of Communication MySQL

  Problem of failure for you, then you are better off rechecked the it AND adding a

  request validation.  ColdFusion 8.0 introduced a field in dsn definition

  for a Validation request.  It works this way: when a database connection is

  created first AND each subsequent time this connection is extract return

  from the pool, the validation request will run BEFORE all queries for the page

  request.  If the validation request fails, the request of your page will never see

  the error because ColdFusion will throw this db connection and get

  another connection from the db connection pool.  It will work then the

  validation query too for this connection.  If this an errors, ColdFusion

  will continue at the close of the bad connections and check other connections

  until now no connection doesn't stay in the connection pool.  If she actually

  got this extreme (which means that every connection in the pool is proven to be bad)

  then ColdFusion will then create a NEW db connection and use that one, and

  It will run the validation on it also query.  All this happens before

  your application runs to ensure that your application receives a good db connection

  from the very beginning.

  A good validation query is something that is very effective for db

  There is not really having to run it.  For MySQL, you can use: select 1

  That's all.  Only enter the field of validation for the data source query

  and keep connections keep checked to improve efficiency with connection

  pooling.

  Make sense?

• HP purchased Folio 13 about 22 months ago. often get error not responding

  I am operating Windows 7 and I have the folio 13 base.  Since the purchase I did nothing for leaving my computer except for the defragmentation.  I was wondering if there is a way, I could sure it works the best efficiency.  Skype always displays an error on startup when I open my contacts list.  Advice on improving the speed of the computer would be greatly appreciated.  Finally, I recently spilled water on the keyboard.  It is important to have the computer open for inspection?  It has been 3 weeks and it starts very well!

  If it has been 3 months, I wouldn't try to open it and inspect.

  For the interview, I would recommend running HP Support Assistant and performs updates and options tuneup.

• ColdFusion 10 - Communications MySQL link failure

  We are the migration of Web sites on a cloud infrastructure running Windows 2008 virtual machines.  These sites all run on ColdFusion with MySQL database.  Currently, they run in our camp with no problems.  In addition, they run on our network of development in our offices without any problem.

  We implement our cloud to match as much as possible the configuration that we currently use, that is, in essence, CF10 + IIS on a server and MySQL on a separate machine.  We are 99% completed and most of the things are running great.  However...

  We met a couple, like 2, places where we click a link/button and are greeted with:

  Run database query error.

  Failed to bind communication of the last packet received successfully from the server was ago 0 milliseconds. The last package successfully sent to the server was ago 0 milliseconds.

  I also find the stack trace analysis:

  "Caused by: java.net.SocketException: Connection reset'.

  The communication link error is ALWAYS: 0ms.

  What is more amazing is the queries that seem to be causing this are * simple * queries that are used ACROSS sites without any problems.  Why they do not reach these 2 particular places we was to end.

  Our only clue is, looking at the CF error description of which scripts are called, we can see the script where the request is a failure is called twice?  For example, among the occurrences is in our application:

  > the error occurred in D:/Our_Web_Sites/oursite/Application.cfm: line 73

  > called from D:/Our_Web_Sites/oursite/Application.cfm: line 17

  > called from D:/Our_Web_Sites/oursite/Application.cfm: line 1

  > called from D:/Our_Web_Sites/oursite/Application.cfm: line 73

  > called from D:/Our_Web_Sites/oursite/Application.cfm: line 17

  > called from D:/Our_Web_Sites/oursite/Application.cfm: line 1

  We can find nothing in our code of the CF could be at the origin of the script to call twice for our guess is the first call fails on the request for CF try again... only to failure and the error.

  Googling this issue I found a lot of posts on the modification of delays of MySQL.  None of those who have worked and I didn't expect to since what we have dealing to doesn't seem to be a timeout issue.  These pages fail every time.

  The closest we came to a solution came from this blog:

  http://www.TalkingTree.com/blog/index.cfm/2011/1/12/validation-query-for-MySQL-communicati ons-link-failure

  If UNCHECK us "Maintain connections across requests customer." in CFAdmin, then the error disappears.  The blog suggests leaving checked, that is our preference and using the "SELECT 1" connection Validation;.  Try this... same error.

  We also tried the JDBC = true option connection.  No effect.

  Downloaded the latest JDBC connector and used instead of the standard CF10-MySQL connector.  No effect.

  In addition, 99% of the site works with the exception of these two links, which work fine in all other workplaces.  Any other ideas?

  Found the problem.  We manage our network on Cloud Computing of the Savvis infrastructure.  The Windows Server instances that use of Savvis had Trend Micro Deep Security Agent installed.  This is an intrusion protection system and that was the problem.  The deactivation of the service cleared up all communication errors.  I have no idea why he was rejecting some queries that he had simply agreed previously.  I'm just happy to (finally) put this behind me!

• I often get in a loop when creating a projector.  Something causes error dialog boxes saying that a supplement is either missing or was not initialized successfully. What causes this?

  Director 11.59 and 12 I get error dialog boxes when I run a movie who say, ' additional text is either missing or does not initialize properly.  No matter what I do with the text Xtra, it does not affect the problem one way or another. Is this a known issue?  How can I fix it?

  Thanks to anyone who can help me.

  Hello Dewey,

  You see this error message when...

  1 # when you try to run a Director published the projection file (either a windows. EXE, or a mac file. File APP)?

  OR

  2 # when you load a .dir file into Director for programming?

  If it's the number 1 #-then you will need to link your xtras in your projection file.

  See the tabs along the top of the screen of the Director (less change & file)

  Modify > movie > xtras > TextXtra PPC (included in the projector - is checked)

  file > publishing settings > files (make sure exclude all xtras is NOT checked)

  If it's number # 2 - so you can have two copies of the xtra text inside your configuration/xtras folder (but it's not likely)

  (* if you try to make an iOS app - then text xtra doesn't either)

• When the Manager of the custom function in a configuration of link file gets error?

  The question she get error when the Manager of the custom function in a config file in the plan to include the link.

  So is there any problem for < custom function platform = "DotNet"?
  
  OPA version 10.2
  
  OPA error message translated from the Germany into English: Exception has been thrown by the target of a call

  In general, you should not give the full path of the custom function, it should be rather in relation to the project include file.

  for example:
  

  and then make sure that the CustomFunctions.dll file is copied into the project folder until the project is built.

  In addition, if you use 10.2 for a new project, the mechanism that you use is now replaced. An extension of the custom function is the new thing, and it will look much nicer when it is used in the rules. Refer to the section 'Write a Custom function Extension' in aid of developer for more information.

• Each cycle of operation of 5 I get error 50405

  Dear,

  I am trying to solve this problem for the last month, it make me crazy every day.
  I posted the same post ago last month and I got the answer from the experts OR, that its the problem of leting the vi running for only 5 cycle (previously showed only after 2 cycle), after the 5-cycle the error appear again.

  More information link

  I tried to solve the problems to the existing solution in this forum. I still get error 50405

  Here's my vi updated seal and some information, hope someone can help you resolve this error.

  Thanks for your support and help Lynn.

  Hi MESHA'AL,.

  Error-50405 is normally related to an error in communication between your device and your computer. I suggest updating your DAQmx driver to the most recent who will support your version of LabVIEW. See the compatibility chart for more details.

  I also suggest upgrading your computers USB drivers and try the different USB ports, hubs and even the cable if you have another.

  If possible, try to run your program on another computer to see if you can reproduce the behavior on another system.

  Finally, if the presists of the error, try to run some of the sample code provided with LabVIEW so we can narrow this down to a problem with your code. At this point I'm leaning more towards a driver/hardware however problem.
