Migrating to Oracle
To switch to an Oracle database, install Oracle and follow the steps below. When they are used together, Fisheye and Crucible share the same external database.
Note that during the migration of database servers, the Fisheye/Crucible instance will not be available to users or to external API clients.
Oracle support for Fisheye/Crucible and Crucible was introduced in version 2.5.0. In order to migrate to Oracle, your instance must be currently running at least version 2.5. If you are running an older version, then you will be required to first upgrade Fisheye/Crucible and then migrate.
Step 1. Install and Create a Oracle Database
- The JDBC drivers for Oracle are bundled with Fisheye/Crucible. Skip to step 2 if this meets your needs. If you want to install a specific, different version of the bundled JDBC driver, download the Oracle JDBC driver
.jarfile from the Oracle website (http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html) and copy the
.jarfile to your
FISHEYE_INST/libdirectory (create the
lib/directory if it doesn't already exist). Move the existing JDBC
.jarfile to another location (and back it up). Restart Fisheye/Crucible to have it pick up the new driver.
- Because creating a database with Oracle is a complex process, we recommend speaking to your resident DBA for creation of a new database for usage with Fisheye/Crucible. We highly recommend installing Oracle with the
AL32UTF8encoding otherwise you may see encoding issues in the product.
Ensure the database user has CREATE TABLE, CREATE SEQUENCE and CREATE TRIGGER permissions in addition to the read/write permissions to the database.
Step 2. Configure Fisheye/Crucible to use Oracle, and Migrate Data
In order to migrate to a different database backend, you must create a backup of sql data, configure the database and finally import the data via a backup restoration process. This can be done from either the Fisheye/Crucible administration console, which streamlines the process, or via the command line tool which Fisheye/Crucible provides.
Option 1: Migrate using the UI (Fisheye/Crucible Administration)
- Navigate to the
Databasepage in Fisheye/Crucible's Administration console.
To log in to the Admin area, you can either:
- click Administration at the foot of the page.
- navigate to
HOSTNAMEis the name of the server on which you installed Fisheye.
Once logged in as an administrator you can also get to the Admin area by clicking the 'cog' menu in the Fisheye/Crucible header, and choosing Administration.
- Then choose Edit > Test Connection to verify that Fisheye/Crucible can log in to the database.
Oraclefrom the database type
- Fill in the appropriate fields, replacing the host, port, database name, username and password using the same connection details as used when creating the Oracle database in Step 1 above.
- Click on
Test Connectionto validate the values

If this fails, verify that you have the Oracle JDBC driver
.jarfile in the classpath (by placing the
FISHEYE_INST/lib). Also, ensure that the database user can log in to the database from the machine that Fisheye/Crucible is running on and that all the required privileges are present.
- Click Save & Migrate Data to start the migration process.
During the migration process (which will take several minutes, depending on the size of your database and network throughput), the product will be inaccessible to users and external API clients. Users will see a maintenance screen that informs them of the process. Should the migration fail for any reason, Fisheye/Crucible will not switch to the new database and report on the encountered problems. Because the destination database may now contain some, but not yet all data, drop all tables, indexes and constraints before attempting a new migration.

Option 2: Migrate using the command line
- Create a backup of the
sqldata from the Fisheye/Crucible instance. Information on how to create a backup can be found at Backing up and restoring Fisheye data \ Backing up and restoring Crucible data
Run the following command from the
<FishEye installation directory>/bindirectory
$ ./fisheyectl.sh restore --sql \ --file /path/to/backup.zip \ --dbtype oracle \ --jdbcurl jdbc:oracle:thin:@hostname:port:dbname \ --username crucible \ --password password
- When the import is complete, Fisheye/Crucible can be started and will use Oracle.
