  1. First, Locate and copy the necessary jdbc driver for your database into <frevvo-home>\tomcat\lib.
  2. Edit the file <frevvo-home>\tomcat\conf\server.xml
  3. You will see a data source definition for the frevvo database type name="jdbc/sharedfrevvoDS". See the sample below of the HSQLDB data source in the server.xml file.
  4. Comment out the pair of the definitions for the default database (HSQLDB) using the <!-- --> comment characters. The entire section must be commented out:


Code Block
		SQLSERVER Resource
	  <Resource auth="Container"
		validationQuery="select 1"

Database configuration has been removed from the <frevvo-home>\tomcat\conf\Catalina\localhost\frevvo.xml file. It is now done in the C:<frevvo-home>\tomcat\conf\server.xml file. Also, notice the database resource name has been changed to jdbc/sharedfrevvoDS.  When you configure your database, make the changes to the v7.0 server.xml. Do not copy configured sections from a frevvo.xml of a previous release into the v7.0 server.xml file.

Configure the frevvo database


2) Verify that the user and password required to connect to the frevvo database are correct.
3) Make sure that the user configured in the data sources has permissions to read and write to the frevvo database.


If you are using SQL Server, it is recommended that you append the sendStringParametersAsUnicode property with a value of false to your database connection URL. This property will improve performance. You can find more information about this property on this Microsoft website. If you do not see the property, when configuring the Connection URL to your database, add it.

Non Standard Databases

If you are trying a different database type and do not see an example in server.xml for your database, you can create a new data source entry. Hibernate supports the following dialects however

 has only been certified to run with a subset of these databases. For additional dialects see Hibernate documentation. 


Code Block
ALTER DATABASE frevvo CHARACTER SET utf8 COLLATE utf8_unicode_ci;
ALTER TABLE `frevvo16089`.`formsubmission` CHARACTER SET utf8 COLLATE utf8_unicode_ci; 

Configure Snapshot Isolation for SQL Server Databases

If you are using SQL Server as your Live Forms database, it is highly recommended that you turn on the READ COMMITTED SNAPSHOT setting in the database.

You do not have to do this if you are using MySQL or Oracle databases because the READ SUBMITTED SNAPSHOT is turned on by default.

There are two ways to turn on the option:

  1. Using DDL ( Data Definition Language) - Run the commands listed below

    Code Block
    ALTER DATABASE <your frevvo database schema> - replace <your frevvo database schema> with the name of your frevvo database schema 
  2. Using SQL Server Management Studio:
  • Turn on the “Is Read Committed Snapshot On” Option under database properties.

Install a JDBC Driver

database relies on the JDBC API. You can use any relational database as long as you have a JDBC driver for that database, however. See the list of certified databases. If you choose a database that's not in this list you do so at your own risk.


It is also appropriate to copy the driver into any location that is in the CLASSPATH of your servlet container. In a tomcat installation another . Another location would be <CATALINA_HOME>/lib.
