SetAbort

Declares that a transaction on a transaction server should be rolled back.

To roll back a transaction

Use

For OLETxnObject objects

Syntax 1

For TransactionServer objects

Syntax 2


Syntax 1: For OLETxnObject objects

Description

Declares that the current transaction should be rolled back.

Applies to

OLETxnObject objects

Syntax

oletxnobject.SetAbort (  )

Argument

Description

oletxnobject

The name of the OLETxnObject variable that is connected to the COM object


Return value

Integer.

Returns 1 if it succeeds and -1 if an error occurs.

Usage

Call the SetAbort function from the client to force a COM+ transaction to be rolled back. The default is to complete the transaction if all participants in the transaction on the COM+ server have called SetComplete or EnableCommit.

Examples

The following example shows the use of SetAbort in a component method that performs database updates:

integer li_rc
OleTxnObject lotxn_obj
lotxn_obj = CREATE OleTxnObject
li_rc = lotxn_obj.ConnectToNewObject("pbcom.n_test")
IF li_rc <> 0 THEN
   Messagebox( "Connect Error", string(li_rc) )
   // handle error
END IF
lotxn_obj.f_dowork()
lotxn_obj.f_domorework() 
IF /* test for client satisfaction */ THEN
      lotxn_obj.SetComplete()
ELSE
      lotxn_obj.SetAbort()
END IF
lotxn_obj.DisconnectObject()

SetComplete

Syntax 2: For TransactionServer objects

Description

Declares that a component cannot complete its work for the current transaction and that the transaction should be rolled back. The component instance are deactivated when the method returns.

Applies to

TransactionServer objects

Syntax

transactionserver.SetAbort (  )

Argument

Description

transactionserver

Reference to the TransactionServer service instance


Return value

Integer.

Returns 1 if it succeeds and -1 if an error occurs.

Usage

The SetAbort function corresponds to the rollbackWork transaction primitive in EAServer.

Any component that participates in a transaction can roll back the transaction by calling the rollbackWork primitive. Only the action of the root component (the component instance that began the transaction) determines when EAServer commits the transaction.

Examples

The following example shows the use of SetAbort in a component method that performs database updates:

// Instance variables:
// DataStore ids_datastore
// TransactionServer ts
 
Integer li_rc
long ll_rv
 
li_rc = this.GetContextService("TransactionServer", ts)
IF li_rc <> 1 THEN
      // handle the error
END IF
...
...
ll_rv = ids_datastore.Update()
IF ll_rv = 1 THEN
      ts.SetComplete()
ELSE
      ts.SetAbort()
END IF
