Environment variable CQL_CONFIG_FILE must point to a valid configuration file. A sample configuration file, called cqlconfi, is included with the distribution.
Note that CQL_CONFIG_FILE must point to a complete file name, and not just a directory. There is no default configuration file name.
The method of setting the environment variable varies with the operating system and the shell that you are using. If you are unsure how to set the environment variable, send an email with your operating system and shell and we will send you information about setting the environment variable.
