Error:
Error DRG-10700: preference does not exist: CTXSYS.DEFAULT_LEXER
Reason:
This error indicates that you do not have any preferences installed. When installing the Oracle® server software, the InterMedia should get installed automatically with the default preferences. These are dependent on the operating system language. You can install the French preference if the language of your Oracle server is French, or the English one if the language of your Oracle server is English.
Action:
Install the appropriate language-specific default preferences. There are scripts in …/ctx/admin/defaults which create language-specific default preferences. They are named in the form of drdefXX.sql, where XX is the language code (from the Server Reference Manual).
To install the US defaults, for instance:
sqlplus ctxsys/<password> @defaults/drdefus.sql
To install the French defaults, for instance:
sqlplus ctxsys/<password> @defaults/drdeffrc.sql
Grant ‘all privileges’ to ctxsys within Oracle.
After these steps, the InterMedia Context server should start.
