ocilogon(): Error while trying to retrieve text for error ORA-01804

I had install scriptcase 9, but there is error when create oracle database connection. When i test connection, display error message : [SIZE=12px]ocilogon(): Error while trying to retrieve text for error ORA-01804.
Scriptcase 8 installed in the same server, and its fine.Then I tried to install on new server display the same error.
I have install with the steps on scriptcase manual. I have set the environment variable too : LD_LIBRARY_PATH, ORACLE_HOME, NLS_LANG.
My Os ubuntu 16.04 64 bit.
What can i do to solve this problem ?[/SIZE]
