OCI-12705

Cannot access NLS data files or invalid environment specified

Cause

Either an attempt was made to issue an ALTER SESSION command with an invalid NLS parameter or value; or the environment variable(s) NLS_LANG, ORA_NLSxx, or ORACLE_HOME was incorrectly specified, therefore the NLS data files cannot be located.


Action

Check the syntax of the ALTER SESSION command and the NLS parameter, correct the syntax and retry the statement, or specify the correct directory path/values in the environment variables.
