MySQL Error 4068: Missing Replication Positions
Description
This error occurs when you attempt to disable GTID_ONLY and SOURCE_AUTO_POSITION for a MySQL replication channel without providing specific binary log file and position coordinates (`SOURCE_LOG_FILE`, `SOURCE_LOG_POS`). MySQL requires these explicit positions to ensure a valid starting point when switching from GTID-based auto-positioning to traditional file/position-based replication.
Error Message
When disabling GTID_ONLY and SOURCE_AUTO_POSITION FOR CHANNEL '%s' you must provide SOURCE_LOG_FILE and SOURCE_LOG_POS as source positions are invalid.
Known Causes
3 known causesOmitting Binary Log Positions
You executed a `CHANGE REPLICATION SOURCE TO` statement with `GTID_ONLY = OFF` and `SOURCE_AUTO_POSITION = 0` but failed to include the necessary `SOURCE_LOG_FILE` and `SOURCE_LOG_POS` parameters.
Incorrect Replication Command Syntax
The command used to modify the replication channel was syntactically incomplete for the desired mode change, specifically missing the source position parameters required for traditional replication.
Misconfigured Replication Transition
The attempt to switch a replica from GTID-based auto-positioning to manual binary log file/position tracking did not account for the mandatory specification of the new starting coordinates.
