MariaDB Error 1397: Unknown XA Transaction ID
Description
Error 1397, XAER_NOTA, signifies that MariaDB cannot find a global XA transaction matching the provided XID (eXtended Transaction ID). This usually occurs in distributed transaction processing when attempting to commit or rollback a transaction that is either unknown, already completed, or never existed on the server.
Error Message
XAER_NOTA: Unknown XID
Known Causes
4 known causesIncorrect XID Provided
The XID specified in the XA command does not match any active or prepared distributed transaction known to the MariaDB server.
Transaction Already Processed
The distributed transaction associated with the XID has already been committed or rolled back by another process or participant, making subsequent operations on it invalid.
Server State Loss
A MariaDB server restart or an unexpected shutdown may have resulted in the loss of knowledge about prepared XA transactions, rendering their XIDs unknown.
Distributed Coordination Mismatch
In a multi-resource distributed transaction, the transaction coordinator or other participants may have lost sync or have a conflicting view of the XID's state with MariaDB.
