MySQL Error 1397: XA Transaction Not Found
Description
This error indicates that an XA (eXtended Architecture) transaction operation, such as COMMIT or ROLLBACK, was attempted using an XID (transaction identifier) that MySQL does not recognize. It typically occurs when the server has no record of an active XA transaction corresponding to the provided XID, leading to a failure in completing the distributed transaction.
Error Message
XAER_NOTA: Unknown XID
Known Causes
4 known causesXA Transaction Already Completed
The XA transaction identified by the XID has already been successfully committed or rolled back by another process or an earlier attempt, making the current XID invalid.
Incorrect or Stale XID
The application provided an XID that is incorrect, malformed, or refers to a transaction that was never started or has expired due to application logic errors or system restarts.
Database Server Restart/Failure
A MySQL server restart or an unexpected crash can lead to the loss of in-memory XA transaction state, causing subsequent operations on previously valid XIDs to fail.
External Coordinator Discrepancy
The external transaction coordinator (e.g., a message queue or application server) is out of sync with MySQL's view of the XA transaction state, leading to attempts to operate on non-existent XIDs.
