Symptoms

When CTX_DDL.OPTIMIZE_INDEX (Rebuild, Full, Token-Type) is run from a session where NLS_LANGUAGE is not American (e.g. Danish, German, Greek), tokens that should have been deleted from the DR$I table are left behind. OPTIMIZE_INDEX either mistakenly truncate the $I tables, or do not correctly optimize all rows in $I tables, or is very slow when locales are other than American.
CTX_DDL.OPTIMIZE_INDEX does not correctly optimize all rows in $I tables.
