Confluence 6 Existing Installation configuration database character Set encoding

For confluence installations that already exist, if the version of Confluence you installed is 6.4 or earlier, we did not check the character settings of your database when installing.

If your database is not currently configured to use UTF-8 encoding (or the same encoding as UTF-8, for example, Al32utf8 encoding used in Oracle):

• You may see a health check warning when you're using confluence.
• You may not be able to start confluence after upgrading confluence

If this problem arises, you need to modify the character set used by your existing database to be UTF-8, and the modification of the character set is different for different methods of data modification.

Please refer to the Troubleshooting Character encodings page for processing of character set issues.

Mysql

See how to Fix the Collation and Character Set of a MySQL database page for more information on modifying characters in your database. You need to make sure that the character set is correct.

Microsoft SQL Server

See how to fix the collation of a Microsoft SQL Server confluence database page to get the details you need when you modify database characters.

PostgreSQL

If you are using a PostgreSQL database, the best way to do this is to re-create your database.

Refer to the database Setup for PostgreSQL page for information on how to create databases and use the correct character set. Please refer to the contents of the migrating to another database page to merge the databases.

Oracle

If you are using an Oracle database, the best way to do this is to re-create your database.

Refer to the database Setup for Oracle page for information on how to create databases and use the correct character set. Please refer to the contents of the migrating to another database page to merge the databases.
