Description

This error occurs when a client attempts to modify the `@@SESSION.GTID_NEXT` variable while an active transaction, for which the client already 'owns' a Global Transaction ID (GTID), is still in progress. MySQL prevents `GTID_NEXT` from being altered in this state to maintain the integrity and sequential assignment of GTIDs within the current session.

💬

Error Message

@@SESSION.GTID_NEXT cannot be changed by a client that owns a GTID. The client owns %s. Ownership is released on COMMIT or ROLLBACK.

Known Causes

3 known causes

⚠️

Modifying GTID_NEXT During Active Transaction

A transaction has been started and assigned a GTID, but has not yet been committed or rolled back, and the client tries to change `@@SESSION.GTID_NEXT`.

⚠️

Uncommitted GTID-Enabled Transaction

A transaction that was initiated with GTID tracking is still open, holding GTID ownership, while an attempt to alter `GTID_NEXT` is made.

⚠️

Client Application Logic Error

The application code might be attempting to manage GTIDs or transaction states in an incorrect sequence, leading to `GTID_NEXT` being set at an inappropriate time.

Solutions

4 solutions available

1. Commit or Rollback the Current Transaction easy

The error occurs because the client session still owns a GTID. Committing or rolling back the transaction releases this ownership, allowing the GTID_NEXT to be changed.

1

If you are in the middle of a transaction and need to change `GTID_NEXT`, first complete the transaction by issuing a COMMIT statement.

COMMIT;

2

Alternatively, if you want to discard the current transaction and then change `GTID_NEXT`, issue a ROLLBACK statement.

ROLLBACK;

3

After the transaction is committed or rolled back, you should be able to set `GTID_NEXT` to your desired value.

SET SESSION GTID_NEXT = '<gtid_set>';

2. Reconnect the Client Session easy

Disconnecting and reconnecting the client session will create a new session that does not own any GTIDs, allowing you to set `GTID_NEXT`.

1

Close your current MySQL client connection. This could be your terminal, GUI tool, or application connection.

N/A (Client specific action)

2

Establish a new connection to the MySQL server.

mysql -u your_user -p your_database

3

Once connected with the new session, you can set `GTID_NEXT`.

SET SESSION GTID_NEXT = '<gtid_set>';

3. Disable GTID Enforcement (Temporary and for Specific Scenarios) medium

If you are performing administrative tasks that require manual GTID manipulation and are not part of normal replication, you can temporarily disable GTID enforcement for the session.

1

Before setting `GTID_NEXT`, set `gtid_next` to `AUTOMATIC`. This tells MySQL to generate the next GTID automatically.

SET SESSION GTID_NEXT = AUTOMATIC;

2

Proceed with your operation that might involve setting `GTID_NEXT` manually if absolutely necessary, but be aware of the implications.

SET SESSION GTID_NEXT = '<gtid_set>';

3

It is highly recommended to revert `GTID_NEXT` to `AUTOMATIC` after your operation or commit/rollback the transaction to release ownership.

SET SESSION GTID_NEXT = AUTOMATIC;

4. Review Application Logic for Transaction Management advanced

If this error is occurring frequently in an application, it indicates a potential issue with how the application manages transactions and GTIDs.

1

Examine your application's code to identify where `SET SESSION GTID_NEXT` is being used.

N/A (Application code review)

2

Ensure that any transaction that involves setting `GTID_NEXT` is properly committed or rolled back before attempting to change `GTID_NEXT` again in the same session.

N/A (Application code review)

3

Consider using separate sessions for operations that require manual GTID manipulation versus regular application operations to avoid conflicts.
