Configuring UTF8 Character Set for MySQL

To create a MySQL database which uses the utf8 character set:

1. Create a new database:

   create database <database_name> character set UTF8 collate utf8_bin

2. Open <TeamCity Data Directory>/config/database.properties, and add the characterEncoding property:

   connectionProperties.characterEncoding=UTF-8

To change the character set of an existing MySQL database to utf8:

1. Shut the TeamCity server down.

2. From the <TeamCity Home>/bin directory, export the database using the maintainDB tool:

   maintainDB backup -D -F database_backup

   More details on this backup are here.

3. Create a new database with utf8 as the default character set, as described above.

4. Modify the <TeamCity Data Directory>/config/database.properties file by changing the connectionUrl property to:

   jdbc:mysql://<host>/<new_database_name>

5. Import data the new database:

   maintainDB restore -D -F database_backup -T <TeamCity Data Directory>/config/database.properties

6. Start the TeamCity server.
