Commits an XA-compliant transaction

Synopsis

xa_commit

Environment

Oracle Tuxedo

Scope

Client, Server

Description

The xa_commit command commits the current transaction, initiated by xa_begin. Once initiated, a transaction must be completed by a call to either xa_commit, xa_rollback, or xa_end.
For example, the following transaction calls service DEPOSIT. If successful, the transaction is committed; otherwise, it is rolled back:
xa_begin
service_call "DEPOSIT" ({ACCOUNT, AMOUNT})
if ((@app()->tp_severity > TP_WARNING) \ 
	|| (@app()->tp_return < 0) || (@app()->tp_tran_status < 0))
{
	xa_rollback
	return 0
}
xa_commit
return 0
xa_commit can set the tp_return property to one of these values:

TP_COMMIT—The transaction is committed.

TP_PARTIAL_COMMIT—The transaction is partially committed.

TP_NOT_COMPLETED—The attempt to commit failed; the transaction remains viable.

TP_ROLLBACK—The attempt to commit failed, the transaction is rolled back.
