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

Tip

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

Your frevvo server requires a SQL database for storing users and form submissions. The default HSQLDB is ONLY sufficient for demo/trial versions of frevvo. All production frevvo users MUST switch their frevvo 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 frevvo 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 thistopic 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 frevvo to Oracle databases. The built in SYSTEM user account will not work.

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 frevvo to Oracle databases. The built in SYSTEM user account will not work.


Configure 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 frevvo has only been certified to run with a subset of these databases. For additional dialects see Hibernate documentation. Refer to our Supported Platforms for the list of Application Servers and databases supported/certified 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

UTF-8 Encoded Database

Note

The frevvo database should be created with UTF-8 encoding if you are using international characters. Setting the encoding depends upon the database you are using. Please consult your database documentation.

If you're using a improperly encoded database for sharedfrevvoDS you may run into one or more of the following runtime issues:

  1. International characters will not work correctly without the proper encoding.
  2. Workflows directed to a specific user may not appear on the user's task list.

...

  1. The frevvo download package comes with pre-installed drivers. For example:
    • the HSQLDB.jar file is located in WEB-INF/lib in the frevvo.war.

    • the SQL Server JDBC Driver - this driver (mssql-jdbc-8.4.1.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 mssql-jdbc-8.4.1.jre11.jar version of the SQL Server JDBC driver.  This version of the driver is included in the frevvo tomcat bundle.


  2. 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
  3. Once you have the driver you need, copy it to <frevvo-home>/tomcat/lib.
    1. The <frevvo-home>\tomcat\logs\frevvo.log file will report an error if you do not copy the JDBC driver to lib directory. The verbiage may differ depending on the driver and database. For example, the error for MySQL is "Cannot load JDBC driver class 'com.mysql.cj.jdbc.Driver". Starting frevvo without the correct jdbc driver displays an HTTP 404 error. Copying the correct jdbc driver to the <frevvo-home>/tomcat/lib directory should resolve the issue.
    2. It is also appropriate to copy the driver into any location that is in the CLASSPATH of your tomcat installation. Another location would be <CATALINA_HOME>/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.
