由 半世苍凉 提交于 2019-12-10 10:35:34
问题 How would I use two separate dataSources in my Spring Boot application? I would like one dataSource to be used by my application, to be used for persisting my models and a separate dataSource for use by the Activiti engine, so it can keep it's entities in a separate database.

Are there JNDI namespace conventions?

由 泄露秘密 提交于 2019-12-10 06:29:54
问题 I have downloaded JBoss EAP 6.1 and I am going to add a new data source. I must bind the data source to a JNDI name. By reading the JNDI name of the sample data source which is: java:jboss/datasources/ExampleDS I see that they have used datasources after java:jboss . Is this just a naming convention - that I am not able to find anywhere - or would it be fine using java:jboss/bananaboat/MyDS ?` Is it correct that the first part that is listed below - such as java:comp is the scope and the rest

How to configure a global JNDI datasource in Tomcat 6?

由 穿精又带淫゛_ 提交于 2019-12-09 13:27:52
问题 I'm struggling to configure a simple JNDI pooled datasource in Tomcat 6.0.32. I want to create the datasource definition outside my web application artifact. Basically I don't want my application to know the credentials to access the database server. I was under the assumption that, like in Weblogic, it should be possible to create a "global" JNDI datasource in Tomcat, but so far I have been unsuccessful. I have tried to add the datasource definition in CATALINA_HOME/conf/context: <Resource

问题 Is there a way to develop Bi (Business Intelligence) solutions with Django? Therefore it should be possible to define models with more than one Datasource. Is anybody out there who has experienced BI with Django? How could it work ? 回答1: I'm not sure what your definition of BI is or why you assume that a BI solution requires more than one data source. In my experience, BI means statistical analysis of data. A reporting schema, using dimensional techniques, can be the basis for it. The data is
