MySQL Troubleshooting

Bug and Knowledge Databases

The Community Bug Database

If you don’t understand MySQL’s behavior and believe it is behaving incorrectly, search the bug database. You will probably find a report with the very same problem. If you use an old version of MySQL, you can even find out whether the problem is fixed.

Oracle Customers’ Bug Database

Oracle tracks bugs reported internally or by customers using its internal bug database. If you are an Oracle customer, you can access it and find bugs that were not reported by the community. This database mostly contains real bugs, and you rarely meet reports closed as “Not a Bug” there, because they go though a careful check before they are included.

Oracle’s Knowledge Management database

Oracle makes a regularly updated knowledge database accessible to its customers. It contains product and problem descriptions in more detail than the MySQL Reference Manual. Many articles are created from customers’ use cases, so you may well find the exact problem you have. Some of the articles are published there on the same day that a feature is released, so this is a really good source for actual information.
