FORCE Clause
Specify FORCE to manually roll back an in-doubt distributed transaction. The transaction is identified by the text containing its local or global transaction ID. To find the IDs of such transactions, query the data dictionary view DBA_2PC_PENDING.
A ROLLBACK statement with a FORCE clause rolls back only the specified transaction. Such a statement does not affect your current transaction.
Restriction on Forcing Rollback
ROLLBACK statements with the FORCE clause are not supported in PL/SQL.
The following statement manually rolls back an in-doubt distributed transaction:
SQL> ROLLBACK FORCE ‘25.32.87’;
