Analyze index <name> compute statistics does not analyze DOMAIN index
When I try to analyze the domain index - it says Analyzed but does show the old date in Last Analyzed in TOAD
It is a valid index as shown in TOAD (not failed or in loading)
How to make sure I analyzed the domain index...

What is your 4 digit database version?
You should not be using that syntax.
Instead use DBMS_STATS.GATHER_INDEX_STATS().
From the documentation
User-Defined StatisticsThe
DBMS_STATSpackage supports operations on user-defined statistics. When a domain index or column is associated with a statistics type (using theassociatestatement), operations on the index or column manipulate user-defined statistics. For example, gathering statistics for a domain index (for which an association with a statistics type exists) using the GET_INDEX_STATS Procedures invokes the user-defined statistics collection method of the associated statistics type. Similarly, delete, transfer, import, and export operations manipulate user-defined statistics. -

When I use Analyze syntax - it works for normal indexes and even in case of DOMAIN index it returns: Index analyzed ... but last analyzed is not reflecting this for the DOMAIN only index
-
dbms_stats.gather_index_stats works fine
-
The "compute statistics" syntax of the "ANALYZE ..." command was deprecated in Oracle 11.2.
You should be using dbms_stats for that now.

Since I started to execute dbms_stats.gather_index_stats on weekly basis from 'command line' - the dba task scheduled daily at night started to work for those tables/indexes as well... (it did not work/analyzed through the daily stats before, that is why I started 'manually' - from the script run dbms_stats.gather_...) Can you explain it?
