title: Oracle Instance Client Light (odac 11) and character sets
body: <p>I am trying to connect to oracle db without full installation of oracle client done on the machine.
  I found this helpfull post <a href="http://splinter.com.au/blog/?p=156" rel="nofollow">Using the new ODP.Net to access Oracle from C# with simple deployment</a> but when I try it, I am failed on the next exception: </p>
  
  <p>[Oracle.DataAccess.Client.OracleException <strong>ORA-12737: Instant Client Light: unsupported server character set %s</strong>    at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, OpoSqlValCtx* pOpoSqlValCtx, Object src, String procedure, Boolean bCheck)</p>
  
  <p>at Oracle.DataAccess.Client.OracleException.HandleError(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, Object src)
  ...</p>
  
  <p>I tried to Google it up, but find nothing except "Do not use this character set" suggestions. </p>
  
  <p>I occasionally I am working with NLS_LANG "american_america.US8PC437", but it can be different (client environment) character set.</p>
  
  <p>Do you have any idea how can I extend light instance client with character sets resources?</p>
  
  <p><strong>Thank you!</strong></p>
