The other day I got this annoying oracle error: ORA-12705: Cannot access NLS data files or invalid environment specified. Funny thing I wasn\'t trying to access NLS data fil
In my case, I was creating a database adapter in the oracle weblogic console, solve the problem by doing the following configuration. Windows -> control panel -> region: 1. Change the format to English (United States) date format M / d / yy and 2. Change my address to the United States. Perform this configuration because my machine was configured with the Spanish language, then restart the computer and I worked without problems.
