connection

问题 I am executing some crud's on mssql server 2008 database by connecting remotely. I have business logic in Java with tight code for connection, statement and result set close() in finally block. My doubt is, even when I finish the job the connection port are still open and it takes roughly 20 min to close all connections. I can view the open connection using netstat -a command. I need to quickly close the connections since each operation opens/close connection several times. Hence I see large

问题 Am preparing some code for migrating from VB&SQL Server to our new solution based on JAVA&Oracle DB, so am trying to connect on the SQL Server to query some data and then to put them on our new oracle tables, but when I try to connect via this code: DriverManager.registerDriver(new com.microsoft.sqlserver.jdbc.SQLServerDriver()); Connexion con = DriverManager.getConnection("jdbc:sqlserver://192.168.10.97:1433;databaseName=ArchiveCCE", "test", "test"); it keeps show me the following error :

问题 Althought this question was asked more than one year ago, it's still relevant for me. I'm also trying to provide more information to make this not just a duplicate. As stated in the original question - if you connect to a MongoDB database with Mongoose and the connection fails, the callback gets called with an error but the whole connection attempt thingy is still somehow running in the background (and not being closed) and your script does not terminate.

问题 Note: I'm asking this only because other solutions I've seen to the same or similar problems haven't worked. Situation : I've written a client-server app, that runs fine if the client and the server are both emulators on the PC. A simple socket connection is established by using Telnet. Problem: Now I want the client to be a real Android device. A USB wire is used for connection. The "USB Debugging" mode is on. But, no connectivity takes place between the device and the emulator. What I've

问题 I just installed Firebird for Win64, and I was trying to connect to the employee database which comes pre-packaged with ISQL. Following the steps from the Firebird official QuickStart Documentation I opened the ISQL utility and entered: connect localhost:employee user sysdba password masterkey; As a result I got: Statement failed, SQLSTATE = 28000 Your user name and password are not defined. Ask your database administrator to set up a Firebird login. Strangest thing is that if I navigate to

问题 I'm trying to create a custom connection where I should use web service. So I read the tutorial on security and this one on custom provider. Now I'm trying to create my own login form with 3 fields : Email, password and number. After validation I understood that my /login_check pass in the function loadUserByUsername($username) , but this function took in argument just $username and doesn't take my fields email and number. To execute my web service I need to get my 3 args. How can I customize

问题 I am fighting this error for a few days already. I can't find reasonable explanation about it on the Internet: I use Glassfish 3.1.2.2 (build 5) 2012-12-19T17:54:26.046+0200 javax.enterprise.resource.resourceadapter.com.sun.enterprise.connectors.util WARNING: RAR8068: Using default datasource : __ds_jdbc_ra for pool : JavaHelpPool 2012-12-19T17:54:26.093+0200 javax.enterprise.resource.resourceadapter.com.sun.enterprise.connectors.service SEVERE: RAR8061: failed to load resource-adapter-config

问题 I want to make a mysql connection using visual c++ with visual studio 2010. I have seen this question asked a couple of times, but I can't seem to figure it out.

The files to add to your project and the right code to write. I tried using a lot of different c++ connectors or even the full packages. But without success. I added in the
