Attach Method
The Attach method allows an external application to reconnect to an existing Siebel session. Syntax
Application.Attach(sessionString)

sessionString |
A string containing the Siebel Session Id. The sessionString is typically the output of the Detach method or a value returned from the Siebel cookie. |
Returns
Boolean indicating whether or not the method was successfully executed Used With
COM Data Control, Java Data Bean Examples
Each of these examples instantiates the first COM Data Control instance, logs in to a Siebel Server, detaches this instance, and then gains the session string. It then instantiates the second COM Data Control instance. It does not need to log in again, as it attaches to the existing session by using the session string. This reuses the connection created by the first instance. The following example is for COM Data Control and is written in native Visual Basic: Dim SiebelApplication_first As SiebelDataControl Dim SiebelApplication_second As SiebelDataControl Dim errCode As Integer Dim sessionString As String Dim attachResult As Boolean Dim errText As String
' Instantiate the first instance Set SiebelApplication_first = CreateObject("SiebelDataControl.SiebelDataControl.1")
' Login to Siebel SiebelApplication_first.Login "host=""Siebel.TCPIP.none.none://<virtual ip>:<port>/<enterprise>/<object manager>""", "<user id>", "<password>"
errCode = SiebelApplication_first.GetLastErrCode If errCode <> 0 Then errText = SiebelApplication_first.GetLastErrText MsgBox errText Exit Sub End If
' Detach this instance from Siebel and get session id sessionString = SiebelApplication_first.Detach MsgBox "The session string is: " & sessionString
' Instantiate the second instance Set SiebelApplication_second = CreateObject("SiebelDataControl.SiebelDataControl.1")
' Attach the existing session to this instance attachResult = SiebelApplication_second.Attach(sessionString) If (attachResult = True) Then MsgBox "Session attached!" Else MsgBox "Session attach failed" End If
SiebelApplication_second.LogOff Set SiebelApplication_second = Nothing Set SiebelApplication_first = Nothing
The following example is for Java Data Bean: import com.siebel.data.*; import com.siebel.data.SiebelException;
public class JDBAttachDetachDemo { private SiebelDataBean m_dataBean_first = null; private SiebelDataBean m_dataBean_second = null;
public static void main(String[] args) { JDBAttachDetachDemo demo = new JDBAttachDetachDemo(); }
public JDBAttachDetachDemo() { try { // Instantiate the Siebel Data Bean m_dataBean_first = new SiebelDataBean();
// Login to the servers m_dataBean_first.login("siebel.TCPIP.none.none://<virtualip>:2320/<enterprise>/<object manager name>","<user id>","<password>");
System.out.println("Logged in to the Siebel server ");
//Get the Detach Handle String detachHandle = m_dataBean_first.detach(); System.out.println("The session id is: " + detachHandle);
// Instantiate another Java Data Bean SiebelDataBean m_dataBean_second = new SiebelDataBean();
// Do Attach System.out.println("Attaching in to the Siebel server "); m_dataBean_second.attach(detachHandle); System.out.println("Attach Done ");
// Logoff m_dataBean_second.logoff(); }
catch (SiebelException e) { System.out.println(e.getErrorMessage()); } } }
