TPABORT()
signifies the abnormal end of a transaction. When this call returns, all changes made to resources during the transaction are undone. Like TPCOMMIT()
, this routine can be called only by the initiator of a transaction. Participants (that is, service routines) can express their desire to have a transaction aborted by calling TPRETURN()
with TPFAIL()
.
If TPABORT()
is called while communication handles exist for outstanding replies, then upon return from the routine, the transaction is aborted and those communications handles associated with the caller's transaction are no longer valid. Communications handles not associated with the caller's transaction remain valid.
For each open connection to a conversational server in transaction mode, TPABORT()
will send a TPEV-DISCONIMM
event to the server, whether or not the server has control of a connection. Connections opened before TPBEGIN()
or with the TPNOTRAN
setting (that is, not in transaction mode) are not affected.
The TPABORT()
argument, TPTRXDEF-REC
, is reserved for future use.
Upon successful completion, TPABORT()
sets TP-STATUS
to [TPOK
].
Under the following conditions, TPABORT()
fails and sets TP-STATUS
to:
Due to a heuristic decision, the work done on behalf of the transaction was partially committed and partially aborted.
Due to some failure, the work done on behalf of the transaction could have been heuristically completed.
When using TPBEGIN()
, TPCOMMIT()
and TPABORT()
to delineate a BEA Tuxedo ATMI transaction, it is important to remember that only the work done by a resource manager that meets the XA interface (and is linked to the caller appropriately) has transactional properties. All other operations performed in a transaction are not affected by either TPCOMMIT()
or TPABORT
.
