Description

Allows a component to find out whether it is running on a transaction server.

Applies to

TransactionServer objects

Syntax

transactionserver.Which (  )

Return value

Integer.

Returns 0 if the object is not running on a transaction server, 1 if it is running on EAServer (obsolete), or 2 if it is running on COM+.

Usage

The Which function allows a custom class user object to perform different processing depending on its runtime context.

Examples

The code in the following example checks to see whether the runtime context is a transaction server. If it is, it uses transaction semantics that are appropriate for a transaction server; otherwise, it uses COMMIT and ROLLBACK to communicate directly with the database:

// 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 ts.Which() > 0 THEN
      IF ll_rv = 1 THEN
         ts.EnableCommit()
      ELSE
         ts.DisableCommit()
      END IF
ELSE
      IF ll_rv = 1 THEN
         COMMIT USING SQLCA;
      ELSE
         ROLLBACK USING SQLCA;
      END IF
END IF
