ObjectContext Object

The key functions of ObjectContext is the transaction control on the server.

ObjectContext.SetAbort Method

ObjectContext.SetAbort Method sets the flag of a transaction during processing scripts in an ASP page to about for the script in a transaction has not completed. Therefore the Component Services should not update those related resources even other participating components in the transaction has completed.

Syntax:

SetAbout(
)

 Or in ASP file Imply

<% SetAbout() %>

Parameters:

void

This method has no parameters.

Return Values:

void

This method has no return values.

Remarks:

When an ASP page initiates a SetAbout method to abort a transaction, the related transaction as a whole becomes unsuccessful. Since the transaction ends unsuccessfully, the Component Services should not update those related resources even other participating components in the transaction has completed. And any changes made by the transaction are rolled back.

The @TRANSACTION processing directive should be used to indicate the script should be treated as a transaction.

Examples:

  • Use ObjectContext.SetAbort Method to abort a transaction

    ASP script command:

    <%@ TRANSACTION=Required  LANGUAGE=ScriptLanguage%>
    <%
    If reqqty>stock then
    ObjectContext.SetAbort
    end if
    %>

ObjectContext.SetComplete Method

ObjectContext.SetCommit Method sets the flag of a transaction during processing scripts in an ASP page to complete for the script in a transaction has completed. Therefore the Component Services can check with other participating components in the transaction whether these participating components has completed or not. If all participating components in the transaction has completed and call SetComplete then the related resources can be updated.

Syntax:

SetComplete(
)

 Or in ASP file Imply

<% SetComplete() %>

Parameters:

void

This method has no parameters.

Return Values:

void

This method has no return values.

Remarks:

When an ASP page initiates a SetComplete method to commit a transaction, only part of the related transaction is completed. Since all related component parts of the transaction must call SetComplete for the related transaction to complete as a whole, the Component Services should not update those related resources until all other participating components in the transaction has completed. And after checking all participating component parts of the transaction are commited by the SetComplete method, the Component Services will then update the related resources.

The @TRANSACTION processing directive should be used to indicate the script should be treated as a transaction.

Examples:

  • Use ObjectContext.SetAbort Method to abort a transaction

    ASP script command:

    <%@ TRANSACTION=Required  LANGUAGE=ScriptLanguage%>
    <%
    If reqqty>stock then
    ObjectContext.SetAbort
    else
     ObjectContext.SetComplete
    end if
    %>
