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\Catalina\localhost\frevvo.xml
3. You will see a data source definition for the frevvo database type. name="jdbc/frevvoDS". See the sample below of the HSQLDB data source in the frevvo.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:

<!-- 
		HSQLDB Resource 
	
	<Resource auth="Container"
		type="javax.sql.DataSource"
		name="jdbc/frevvoDS"
		driverClassName="org.hsqldb.jdbcDriver"
		username="sa"
		password=""
		url="jdbc:hsqldb:file:${catalina.home}/../data/db/forms"
		maxActive="200"
		maxIdle="20"
		maxWait="10000"
		validationQuery="select 1 from INFORMATION_SCHEMA.SYSTEM_USERS"
		testOnBorrow="true"
		testOnIdle="true"
		timeBetweenEvictionRunsMillis="10000"
		removeAbandoned="true"
		logAbandoned="true"/>
	
	<Parameter name="org.quartz.jobStore.driverDelegateClass" value="org.quartz.impl.jdbcjobstore.HSQLDBDelegate" override="false"/>	
-->

Next, uncomment the pair of definitions for your database. Ex: if you are using SQL server, uncomment the definition for SQLSERVER Resource. Save the changes.

 <!-- 
		SQLSERVER Resource
 -->		
	<Resource auth="Container"
		maxActive="200"
		maxIdle="20"
		maxWait="10000"
		validationQuery="select 1"
		testOnBorrow="true"
		testOnIdle="true"
		timeBetweenEvictionRunsMillis="10000"
		removeAbandoned="true"
		logAbandoned="true"
		name="jdbc/frevvoDS"
		driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
		username="root"
		password=""
		type="javax.sql.DataSource"
		url="jdbc:sqlserver://localhost:1433;databaseName=frevvo;"/>
	
	<Parameter name="org.quartz.jobStore.driverDelegateClass" value="org.quartz.impl.jdbcjobstore.MSSQLDelegate" override="false"/>			
	

Configure the frevvo database

For the frevvo database type in frevvo.xml

1. Locate the frevvoDS data source url parameter:url="url="jdbc:sqlserver://localhost:1433;databaseName=frevvo". You can change the name "frevvo" to whatever you wish, "" for example. But it must match the database name you create in your SQL server. See verify connection Url below.
2. Create a UTF-8 encoded database "frevvo" (assuming you left the url parameter database name as the default) in your SQL server
3. Set the frevvoDS data source parameters username and password to a user that has write permissions to the frevvo database.
4. The frevvo database setup is now complete.  will create all the necessary table upon startup.

Verify the Connection Url

Configuration of the connection Url is key to successfully connect the  server to your database. Consult your DBA to assist with connection issues.

For the data source frevvoDS 

1) verify that the "url" parameter is pointing to the correct server. If  and the database server are collocated "localhost" may be fine.

The Url parameters depend on the database type and installation choices made when your DBA installed your database software. Consult your DBA for the correct connection values. For example, SQL server installed on a non-default port and running on a machine named e00sca will require that you add a port number and host name to the Url. For example:

<url>jdbc:jtds:sqlserver://e00sca:59377/frevvo</url>

As of SQL 2000, Microsoft SQL allows installation of multiple SQL named instances. If your SQL server was installed this way you must use the instance parameter. For example if you database instance was named xyzzy:

<url>jdbc:jtds:sqlserver://e00sca:59377/frevvo;instance=xyzzy</url>

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 databases.

Non Standard Databases

If you are trying a different database type and do not see an example in frevvo.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. 

•  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

Setting the encoding depends upon the database you are using. Please consult your database documentation.

MySQL UTF-8 Example

These commands will create the proper frevvo utf8 encoded database in mySql:

create database if not exists frevvo default character set "utf8" default collate "utf8_unicode_ci"; 

You can convert a database and/or table to UTF-8. Using the mySQL configuration file or via the mySQL cmd tool.

Via the configuration file:

[mysqld]
default-character-set=utf8
default-collation=utf8_unicode_cii

Via the mySQL cmd tool:

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

Install a JDBC Driver

's submission and user databases rely 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.

The  download package comes with several pre-installed drivers. Look in <frevvo-home>/tomcat/lib and you will see (among other jar files) the following pre-installed driver jar files:

• hsqldb-2.2.4.jar - HSQLDB driver
• postgresql-9.0-801.jdbc4.jar - Postgress driver

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

• SQL Server JDBC Driver
• Oracle 
• MySQL - 5.1.11 or later is recommended to resolve Tomcat memory leak issues.

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

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.jdbc.Driver". Starting without the correct jdbc driver displays an HTTP 404 error. Coying the correct jdbc driver to the <frevvo-home>/tomcat/lib directory should resolve the issue.

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 location would be <CATALINA_HOME>/lib.

Changing the frevvo database naming and escaping conventions

In specific situations, your organization may require a certain naming convention for database objects (all uppercase, or at most 32 chars, or a specific name escaping convention) and the good news is that It is possible to change some of these parameters in  by setting a couple of specific web context parameters.

Note also that the following settings affect only the frevvoDS database schema (and not the userDS schema) and that any changes to these settings will force  to create a schema that is different than the pre-generated scripts found in frevvo/data/sql/forms-*.sql when the schema is initially empty (you have to start from an empty schema).

How can you make sure that all database object names are uppercase or lowercase? You can affect this by  editing the frevvo/tomcat/conf/Catalina/localhost/frevvo.xml and adding the following parameter:

<Parameter name="teneo.naming.strategy" value="uppercase" override="false" />

How can you make sure that all database object names have a max length (e.g. Oracle specifies a max of 32 chars)? You can affect this by  editing the frevvo/tomcat/conf/Catalina/localhost/frevvo.xml and adding the following parameter:

<Parameter name="teneo.naming.max_sql_name_length" value="30" override="false" />

How can you specify a custom name escape character? You can affect this by  editing the frevvo/tomcat/conf/Catalina/localhost/frevvo.xml and adding the following parameter:

<Parameter name="teneo.naming.sql_name_escape_character" value="" override="false" />
