datasource

问题 I'm trying to add a postgresql database as a datasource in IntelliJ IDEA Ultimate. I've worked with a datasource through ONE ssh tunnel already. But now the database server is behind a firewall which only accepts ssh connections from a management server. The only way to access the db server goes over the management server. So I (or IntelliJ) have to connect via ssh to this server and then, by using another user, tunnel via ssh to the database server. Everything clear? :-D The problem is, that

问题 I have an application which dynamically adds databases for each instance of the application, and which then, on JBoss 5 would write a datasource file out into the deploy folder, so that the application could make use of the new database (And be locked down to it). In JBoss 7 the datasource configuration is inside standalone.xml. And more importantly if I enter new datasources into this file, they don't seem to get read and no datasource is available. Does anyone have any idea how I can

问题 I have created the data source in Websphere server and its name is myDataSource(JNDI name is oracleDS). Now I want to access it through the stand alone application. I just wrote the bellow code to access the data sorce. Hashtable<String, String> pdEnv = new Hashtable<String, String>(); pdEnv.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory"); pdEnv.put(Context.PROVIDER_URL, "iiop://localhost:2809"); Context initialContext = new InitialContext(pdEnv);

问题 After configuring the datasources in the jboss 5.0 AS , I deployed the jbpm web application .

问题 We have a coldfusion enterprise server with 2 instances. Each instance has 200+ data-sources to databases on one MSSQL server. This number will keep on growing. Now it seems that requests to a single data-source are getting slower even though the database is small. It is possible that requests get slower when CF has more data-sources? 回答1: Are the datasources partitioned for a reason (e.g. different clients/customers, etc)? If this is really just a big application with a bunch of databases,

问题 my issue is on the ReqTransPOListPage, I added a FactBox Part related by ItemId When the user navigates in the Grid records - If the selected field on grid is one of the main DS ReqPO then the FactBox get refreshed! - But if the selected field on the grid is a field of any sub DataSource of Query, then PCDataSourceEventNotify.onRefresh() is not triggered and neither my FactBox. I can't even force refresh in ReqTrans_DS.active() since it's a ListPage based on AOT Query and datasource methods

问题 I am using Angular 2 and have a grid (ag-grid-angular) with enableServerSideSorting=true and it's working fine only for the first time: the data is loaded and placed in the grid view as expected. When I click on a column to sort that column (which happens automatically) the data is fetched again by calling getRows(params) . The problem is that I have several other input fields: Tabs: to change the type of elements displayed (for example persons or cars). Text field: which is used to enter
