MySQL Error 4015: GTID Mode Off for Replication
Description
This error occurs when attempting to configure replication to assign GTIDs to anonymous transactions, but the MySQL server's global GTID_MODE is not set to 'ON'. The `ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS` option requires GTID functionality to be fully enabled on the server.
Error Message
CHANGE REPLICATION SOURCE TO ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS = LOCAL|<UUID> cannot be executed because @@GLOBAL.GTID_MODE <> ON.
Known Causes
3 known causesGTID Mode Disabled
The `@@GLOBAL.GTID_MODE` system variable is currently set to `OFF` or another non-GTID-enabled value, preventing the use of GTID-dependent features.
Server Not Configured for GTIDs
The MySQL server instance was started or initialized without GTID_MODE enabled, making it incompatible with features like assigning GTIDs to anonymous transactions.
Incorrect Replication Configuration
An attempt was made to use `ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS` in a `CHANGE REPLICATION SOURCE TO` statement on a server not fully prepared for GTID-based replication.
