[Mono-dev] Oracle Managed Client

[Ventsislav Mladenov]

Hi Bojan,
Thanks for the tip, It's look like the fully managed provider is not so 
managed.
With full exception stacktrace and IL spy the result is two P/Invoke 
functions

     [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = 
true)]
     [return: MarshalAs(UnmanagedType.Bool)]
     private static extern bool GlobalMemoryStatusEx([In] [Out] 
OracleTuner.SystemInfo.MEMORYSTATUSEX lpBuffer);
     [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = 
true)]
     private static extern void GlobalMemoryStatus([In] [Out] 
OracleTuner.SystemInfo.MEMORYSTATUS lpBuffer);
