In my VB 6.0 code, I have tried to connect to oracle-database, but program just hang (even there is no exception !!!) Code is :

In alert.log there is a massage (it sometimes occurs when the above hang, but not always when the program hangs) : SMON: Parallel transaction recovery tried

The code in brief:

Public OraCon As New ADODB.Connection
Public mainConnectionStr As String

public sub connectToDB
  On Error GoTo connectToDB_err
  mainConnectionStr = ...
  OraCon.ConnectionString = mainConnectionStr   Call OraCon.Open ' ***** here programs hang sometimes ******

                                ' ***** also, when hang - not always there 
is a line on alert.log, but sometimes there is. ******   goto end_proc
' ****** when the above error, this code is never reachable *******   msgBox "" & err.number & "," & err.description end_proc:
end sub

What may be the cause for the above problem ?
