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.

Info

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.

Code Block
url="jdbc:sqlserver://localhost:1433;databaseName=frevvo;sendStringParametersAsUnicode=false"/>

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

Frevvoproduct
 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 
SET READ_COMMITTED_SNAPSHOT ON
  2. Using SQL Server Management Studio:
  • Turn on the “Is Read Committed Snapshot On” Option under database properties.

Install a JDBC Driver

Frevvoproduct
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.
