database-connection

问题 I open a few oracle connections with oracle jdbc. And I need to test a certain case where the db's password gets expired and the connections should be not working. However, when I manually expire the db password, the connections still stay open and working. What should I do for connections to get closed or to get closed when I expire the db password? 回答1: If a user password expiration occurs in the middle of an already established connection(session), it will not end a user session - the

问题 I have a SQL Server installed on my PC (a terminal). I want to create a new database which its files (mdf & ldf) will be located on a network share. From the files explorer I can easily see the share, but from the user interface of the SSMS - I don't. Is it possible technically to do it? Is it possible to configure the instance to "see" remote drives? 回答1: The reason for not being able to see network shares in SSMS is probably becuase of performance and reliability issues when placing

问题 I was creating a Dashboard in Pentaho PUC which uses a postgres connection as the data source. Most of the time this causes the postgres to say Too many clients already in Postgres' SHOW max_connections; Query shows maximum connections of 200 I used this query select * from pg_stat_activity; .

This looks like Pentaho

问题 We're connecting to an Ads server with a .net application using the Advantage .NET Data Provider. The ServerType = REMOTE. The max. connections on the server is set to 150. When we connect from a client we get a "6303 Maximum Advantage Database Server connections exceeded" error. Turns out it uses the default 50 max. connections for an application.

问题 I am using Spring 3.0.1 and Hibernate 3.2 with JBOSS 4.2.2 and we are using Spring transaction management to manage the transactions. My code implementation runs a huge job that runs for nearly 10 minutes.The spring service bean RunJobBean.java is the entry point for my job and this instantiates a number of independent threads (each performing different DB updates and other logic etc) and these threads invokes the hibernate DAO beans (These are injected into RunJobBean which passes on to

问题 I programmed a website in PHP that uses a MySQL Server through GoDaddy. I have the same code saved on my local computer and sync it with the directory on GoDaddy through an app. I also use XAMPP on my computer to test any changes I make to the website before I make the changes public. However, the localhost server is different and in no way connected with the cPanel GoDaddy server. Therefore, if something new is added to the database on the public server, I would have to Download the sql file

问题 I'm building an application that accesses various databases. Currently the connection strings are stored in the App.Config file. However I'd like to be able to configure the connection strings for the database more easily. I'm considering having a single "master" database that contains the connection strings for all the other databases. This would mean that each application that requires a database connection would lookup the connection from the master database. The App.config file could
