breportheuristics |
A boolean specifying whether heuristic decisions should be reported for the transaction associated with the calling thread |
Return value
Integer.
Returns 0 if it succeeds and one of the following negative values if an error occurs:
-1 -- Failed for unknown reason
-2 -- No transaction is associated with the calling thread
-3 -- The calling thread does not have permission to commit the transaction
-4 -- The HeuristicRollback exception was raised
-5 -- The HeuristicMixed exception was raised
-6 -- The HeuristicHazard exception was raised
Usage
The CommitTransaction function completes the transaction associated with the calling thread. Use the BeginTransaction function to begin a transaction and associate it with the calling thread. The transaction is not completed if any other participants in the transaction vote to roll back the transaction.
CommitTransaction can be called by a client or a component that is marked as OTS style. EAServer must be using the two-phase commit transaction coordinator (OTS/XA).
Examples
In this example, the client calls the dopayroll method on the CmpnyAcct EAServer component, which processes a company payroll. The method returns 1 if the company has sufficient funds to meet the payroll, and the client then commits the transaction:
// Instance variables: // CORBACurrent corbcurr integer li_rc boolean lb_rv long ll_rc // Create an instance of the CORBACurrent object // and initialize it ... lb_rv = corbcurr.BeginTransaction() IF lb_rv THEN ll_rc = myconnect.CreateInstance(CmpnyAcct) // handle error li_rc = CmpnyAcct.dopayroll() IF li_rc = 1 THEN corbcurr.CommitTransaction( ELSE corbcurr.RollbackTransaction() END IF ELSE // handle error END IF
