Configuring the Database Connector

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. Depending on your installation choice, follow

Configuring the Database Connector in the frevvo-tomcat bundle

These steps assume you have already installed the frevvo-tomcat bundle and the Database Connector and have verified that the connector is up and running.

  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.

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

  3. Create the file <frevvo-home>\tomcat\conf\frevvo-config.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-config.properties.

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

      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

      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.

       Click here for Datasource Property Examples

      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".

      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

      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.

      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.

      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.

      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 url http://<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.

Configuring the Database Connector in Standalone mode

These instructions assume you have already installed the Database Connector Standalone bundle and have verified that the connector up and running.

Follow these steps:

  1. Stop the Standalone Database Connector

  2. Navigate to the <db-home>\database-connector-2.5.x\config directory.

    1. Create the file <frevvo-home>\config\configuration.xml.

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

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

  3. Edit <db-home>\database-connector-2.5.x\config\configuration.xml. The dbconnector.properties file is where you can customize database connection properties (such as server port) and configure datasource definitions.

    1. Copy/Paste one of the two following samples under the server.port property.

      Use this sample if all querysets use the same database
      # Customize the DbConnector here
logging.file=./logs/database-connector.%d{yyyy-MM-dd}.log
server.port=8081

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

      Use this sample if querysets use different databases
      # Customize the DbConnector here
logging.file=./logs/database-connector.%d{yyyy-MM-dd}.log
server.port=8081

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>

      You can see more examples of datasource definitions here

  4. Restart the connector using one of these methods:

    • Method 1: Using java in a command window
      1. Navigate to <db-home>\database-connector-2.5.x .Type java -jar database.war
    • Method 2: for Windows OS

      1. Double click the <db-home>\database-connector-2.5.x\Install-Service.bat file to install the connector as a Windows service. Click the Start-DBConnector-Service.bat file to start it

         Click to see standalone bundle content details

        The Standalone Database Connector bundle includes the files shown in the image:

        Note the files in the database-connector-2.5.x directory that are used to manage the Database Connector as services on *nix and Windows operating systems: These files should be run as an administrator.

        • Install-Service.bat - installs the Database Connector on a Windows system as a service named frevvo Database Connector.

        • Uninstall-service.bat - uninstalls the frevvo Database Connector on a Windows operating system

        • Start-DB Connector-Service.bat - starts the frevvo Database Connector on a Windows operating system

        • Start-DBConnector.sh - starts the frevvo Database Connector as a *nix console instance.

        • Restart-DBConnector-Service.bat - restarts the frevvo Database Connector on a Windows operating system

        • Restart-DBConnector.sh - restarts the frevvo Database Connector as a *nix console instance.

        • Stop-DBConnector-Service.bat - stops the frevvo Database Connector on a Windows operating system.

        • Stop-DbConnector.sh - stops the frevvo Database Connector *nix console instance.

    • Method 3 for *nix OS
      1. Execute the  DB Connector.sh shell script for Unix/Linux operating systems.
    • Method 4 for Linux
      1. The Database Connector can also run as a service under Linux systemd

     Click here for the details

    It is possible to manage the Database Connector using systemd ‘service’ scripts.

    1. Copy the sample service file located in /bin/dbconnector.service to /etc/systemd/system
    2. Review it's contents and
    3. Make sure it is executable.

    You can now use systemd to manage the dbconnector service:

    • systemctl start dbconnector.service

    • systemctl stop dbconnector.service

    • systemctl restart dbconnector.service

    • systemctl status dbconnector.service

    To flag the service to start automatically on system boot use the following command:

    systemctl enable dbconnector.service

    Consult the service unit configuration man page for more details.

  5. Browse http://localhost:8081/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.

Database Connector FAQ

What is a database URL?

A database URL is a Universal Resource Locator (URL) that specifies a particular type of database server compatible with the JDBC driver you installed. In addition you can also specify the database name to use for the connection.

The format for the database URL is database driver specific. For example,  the correct format for a MySQL database is:

jdbc:mysql://[host][:port optional]/[database name]

Check with your database administrator or the documentation for your database drive for details on the correct database URL format.

Can I add other parameters to the database URL?

You can add other parameters to the URL. For example, it is recommended that you add the useServerPrepStmts=true parameter to the database connection URL if you are using MySQL as your external database. This property improves the queryset/query validation if a column or table is missing. With this parameter in place, the MySQL driver reports a warning that the table or column doesn't exist.

How do I define datasources on the container level?

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..  
 

Using <Resource-ref> to define datasources is not supported if you are running the Database Connector in Standalone mode. Use <Resource-def> instead.

Follow these steps:

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

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

      <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-config.properties file. Verify that the frevvo.connectors.database.configuration property has been set and add the dbconnector.resource-ref.name property as shown below:

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

How do I Disable 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.

    <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 (tomcat bundle).  

    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). 

    dbconnector.querySet.enabled=false
