These steps are required when you convert from a demo/trial server installation to a production installation.

Tip

While you are demo-ing you do not need to do the Database Setup steps discussed below.

Your  server requires a SQL database for storing users and form submissions. The default HSQLDB is ONLY sufficient for demo/trial versions of . All production users MUST switch their software to a production quality database. The following steps describe how to change the underlying database from the demo/trial HSQLDB to a production quality SQL database. The database configuration file, server.xml is located in <frevvo-home>/frevvo/tomcat/conf directory.

Before you start:

  1. Refer to our Supported Platforms for the list of Application Servers and databases supported/certified by frevvo. frevvo only supports/certifies the  running in the Apache Tomcat container.
  2. Download csv files of your users and roles, as well as any applications from designer user accounts in the trial database. You cannot migrate the data (user, roles, applications) automatically from HSQL to your production database. See this topic for the manual procedure details.
Tip
  • If you are using Oracle12c as your database, the jdbc driver must be version 7 ojdbc.jar for the Refresh Searchable Fields process to function properly. Refer to the Install a JDBC Driver topic for the details.
  • It is recommended practice to use a named user (schema) account with the proper privileges when connecting to Oracle databases. The built in SYSTEM user account will not work.

Select your database type

  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:

Warning

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 server.xml. Do not copy configured sections from a frevvo.xml of a previous release into the server.xml file.



Tip

It is recommended practice to use a named user (schema) account with the proper privileges when connecting to Oracle databases. The built in SYSTEM user account will not work.

Configure the frevvo database

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. 

...

See the certified database list above

...

 for all the databases officially supported by frevvo.

  •  org.hibernate.dialect.HSQLDialect
  •  org.hibernate.dialect.MySQL5Dialect
  •  org.hibernate.dialect.MySQL5InnoDBDialect
  •  org.hibernate.dialect.Oracle9Dialect
  •  org.hibernate.dialect.OracleDialect
  •  org.hibernate.dialect.PostgreSQLDialect
  •  org.hibernate.dialect.SQLServerDialect
  •  org.hibernate.dialect.Sybase11Dialect

...

  • the HSQLDB.jar file is located in WEB-INF/lib in the frevvo.war.

  • the SQL Server JDBC Driver - this driver (mssql-jdbc-7.2.2.jre11.jar ) is included in the frevvo tomcat bundle in the <frevvo-home>\frevvo\tomcat\lib directory.

    Warning

    At this time, frevvo only supports the v7.2.2.jre11 version of the SQL Server JDBC driver.  This version of the driver is included in the frevvo tomcat bundle.

If you don't find what you need pre-installed you will need to locate a driver compatible to your database. Usually you can download your driver from the internet. Try one of these locations

  • MySQL - 8.0.x or later is recommended if you are using MySQL 5.6+

  • Oracle

Info

Once you have the driver you need, copy it to <frevvo-home>/tomcat/lib.

Info

Users on Mac OS may see this exception:

Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value 'EDT' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

Customers facing this error should add the serverTimezone=EST5EDT (insert correct timezone) parameter to the jdbc url.
