Object transaction XPI functions

You can use the object transaction XPI calls to implement a TRUE program that responds to calls between a CICS® unit of work and a remote transaction coordinator. These are the DFHOTTRX calls COMMIT, COMMIT_ONE_PHASE, IMPORT_TRAN, PREPARE, ROLLBACK, and SET_ROLLBACK_ONLY, and the DFHOTCOX call SET_COORDINATOR. These functions provide powerful control over the sync point processing of a CICS unit of work. If you use these calls incorrectly, the CICS Recovery Manager terminates CICS immediately and recovery and resynchronization processing is required.
