The database connector can be installed in either a simple standalone mode or in a servlet container such as the frevvo-tomcat in-house bundle. frevvo only supports/certifies the Database Connector running in the Apache Tomcat container.

Depending on your installation choice, follow

...

1. Stop . You do not have to stop the Insight Server.

2. Create a folder named <frevvo-home>\config i.e. c:\frevvo\config.

   1. Create the file <frevvo-home>\config\configuration.xml. Your SQL statements will be added to this file.

   2. Copy/Paste the follow text into configuration.xml. This skeleton defines test querysets named myStore and BIRT to get you started.

      Code Block
      <dbconnector> <queryset name="myStore"> </queryset> <queryset name="BIRT"> </queryset> </dbconnector>

3. Create the file <frevvo-home>\tomcat\conf\frevvo-configdbconnector.properties. If this file already exists you will add your database datasource properties to it.

   1. Copy/Paste one of the two following samples into frevvo-configdbconnector.properties.

   2. Edit the frevvo.connectors.database.configuration line to be the path to your configuration.xml file.

      Code Block
      title Use this sample if all querysets use the same database
      frevvo.connectors.database.configuration=file:///C:/frevvo/config/configuration.xml dbconnector.queryset.resource-def.url=<the url to your database> dbconnector.queryset.resource-def.user=<your database username> dbconnector.queryset.resource-def.password=<your database password>

      The @myStore and @BIRT in the this sample will be your queryset names in your configuration.xml

      Code Block
      title Use this sample if querysets use different databases
      frevvo.connectors.database.configuration=file:///C:/frevvo/config/configuration.xml dbconnector.queryset@myStore.resource-def.url=<the url to your database #1> dbconnector.queryset@myStore.resource-def.user=<your database username> dbconnector.queryset@myStore.resource-def.password=<your database password> dbconnector.queryset@BIRT.resource-def.url=<the url to your database #2> dbconnector.queryset@BIRT.resource-def.user=<your database username> dbconnector.queryset@BIRT.resource-def.password=<your database password>

      
      Your Datasource Properties depend on your JDBC driver type.

      MySQL example This sample shows a configuration.xml queryset named "alltest" against a MySql database named "test" where the database login user is "root" and the password is "root". Code Block dbconnector.queryset@alltest.resource-def.url=jdbc:mysql://<your database server>:<port>/test dbconnector.queryset@alltest.resource-def.user=root dbconnector.queryset@alltest.resource-def.password=root SQL Server Example This example connects to a SQL Server driver Code Block dbconnector.queryset@BIRT.resource-def.url=jdbc:sqlserver://<your database server>;DatabaseName=<your database name> dbconnector.queryset@BIRT.resource-def.user=<your database user> dbconnector.queryset@BIRT.resource-def.password=<your database password> SQL jTDS Example This example connects to SQL Server using the jTDS driver. The jTDS driver requires the additional validationQuery property. Code Block dbconnector.queryset@myStore.resource-def.url=jdbc:sqlserver://<your database server>:<port>;DatabaseName=<your database name> dbconnector.queryset@myStore.resource-def.user=<your database name> dbconnector.queryset@myStore.resource-def.password=<your database password> dbconnector.queryset@myStore.resource-def.validationQuery=SELECT 1   If your SQL server has multiple SQL named instances, use the url instance parameter as shown here for an instance named xyzzy. Code Block dbconnector.queryset@myStore.resource-def.url=jdbc:sqlserver://<your database server>:<port>;DatabaseName=<your database name>;instance=xyzzy Oracle 11g This example connects to an Oracle 11g driver. Code Block dbconnector.queryset@mystore.resource-def.url=jdbc:oracle:thin:@<your database server>:<port>:ServiceName dbconnector.queryset@myStore.resource-def.user=<your database user> dbconnector.queryset@myStore.resource-def.password=<your database password>

4. Restart

5. Browse the status urlhttp://<host>:<port>/database/status
6. Your skeleton database configuration is successful when the status returns Passed! for each queryset.
   
   
   
   
7.  You are now ready to define your SQL Queries.

...

If you prefer to define your datasources on the container level, the recommended approach is to define the datasource in the container and then use a resource-ref in the Database Connector properties file to reference it..  
 

...

1. Edit <frevvo-home>\tomcat\conf\Catalina\localhost\context.xml.default,
   
   

   1. Add the Resource name parameter. An example is shown below:

      Code Block
      <Resource name="jdbc/<your database name>" auth="Container" driverClassName="com.mysql.jdbc.Driver" username="<your database user>" password="<your database password>" type="javax.sql.DataSource" url="jdbc:mysql://localhost/<your queryset name>?autoconnect=true"/>

2. Edit frevvo\tomcat\conf\frevvo-configdbconnector.properties file. Verify that the frevvo.connectors.database.configuration property has been set and add the dbconnector.resource-ref.name property as shown below:

   Code Block
   dbconnector.queryset@<queryset name>.resource-ref.name=jdbc/<name of your resource>

How do I Disable a QuerySet/Query?

When you are developing your integration, you might want to disable a particular queryset/query so you can focus on the one you are troubleshooting. QuerySets/queries can be disabled in one of two ways:

1. Add the enabled= attribute with a value of false to the <querySet/> or individual <query> elements in the configuration.xml file to completely disable it.

   Code Block
   <dbconnector> <querySet name="BIRT" enabled="false" ...>

2. The same can be done by adding the enabled property with a value of false as shown below to the dbconnector.properties(standalone bundle) or frevvo-config.properties the (tomcat bundle).  

   Code Block
   dbconnector.querySet@<queryset name>.enabled=false

   This property disables all querysets. Add it to the dbconnector.properties(standalone bundle) or frevvo-config.properties (tomcat bundle).

   Code Block
   dbconnector.querySet.enabled=false
