+Summary: new OracleConnection("...") fails with DllNotFoundException: clntsh [incl. WORKAROUND]
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+i try to open an oracle connection on my winXP machine and it fails in mono
+because of a missing "clntsh" (to my knowledge its the the oracle lib for
+i have oracle 8.1.7 client package installed and it works with many other
+programs (programs that use OCI and not ODBC or something), and i have
+Oracle_home etc env-variables set. 
+in my PATH is "...C:\ORANT\ora81\bin...", this is where my oci.dll resides
+opening the connection with msft.net works as expected.
+Steps to reproduce the problem:
+1. fill strings "dsn user pass" with values for your oracle db
+2. con = new OracleConnection("DATA SOURCE="+dsn+";"+"USER
+Actual Results:
+Unhandled Exception: System.DllNotFoundException: clntsh
+in (wrapper managed-to-native) OciNativeCalls:OCIEnvCreate
+in <0x0001f> System.Data.OracleClient.Oci.OciCalls:OCIEnvCreate

+ramem_sz, IntPtr usrmempp)

+in <0x0010a> System.Data.OracleClient.OracleConnectionPool:GetConnection ()
+in <0x000ce> System.Data.OracleClient.OracleConnection:Open ()
+in (wrapper remoting-invoke-with-check)
+System.Data.OracleClient.OracleConnection:Open ()
+Expected Results:
+it should work :-D
+How often does this happen? 
+Additional Information:
+i have found a workaround..... but its very ugly i think
+cd C:\ORANT\ora81\bin (My path to oracle)
+copy oci.dll clntsh.dll
+then it works like expected
+i have cygwin installed but i have stopped my x server, removed cygwin from
+PATH and renamed c:/cygwin to something else to not confuse mono that im on
+unix or something ....
