Alternatively, create the functionality such that a click of the button will save the configuration and will trigger a restart of the application.

Workaround

Note: If you are editing database settings to use an existing database ensure you are using a version of the application compatible with the database schema version.
Note 2: In order to have data and configuration from another instance in a new instance, prefer to follow the https://confluence.atlassian.com/display/FISHEYE/Backing+up+and+restoring+FishEye+data document instead of just editing the database settings.

Steps:

1. Stop FishEye/Crucible.
2. Open your config.xml located in your <FISHEYE_INST> directory.
3. Identify the database configuration XML element and edit the attributes as required (this example is for MySQL):

   <database type="mysql"><connection dialect="org.hibernate.dialect.MySQL5InnoDBDialect" driver="com.mysql.jdbc.Driver" jdbcurl="jdbc:mysql://localhost:3306/fisheye340" password="password" username="grefosco" maxPoolSize="20" minPoolSize="5" driverSource="bundled"/><parameters>useUnicode=true
   characterEncoding=UTF8
   connectionCollation=UTF8_bin
   </parameters></database>
   

4. Start FishEye/Crucible.
