Juan,
I'm the author of that article. You don't have to use STATSPACK to get the
segment stats data. All you have to do is to set the STATISTICS_LEVEL
init.ora parameter to TYPICAL, or just don;t define it at all and the
v$segstat will be populated. If it's not populated, I would suspect the
parameter has been set to BASIC. You can reset it using ALTER SYSTEM.
You can check the settings by:
SELECT ACTIVATION_LEVEL, STATISTICS_NAME, SYSTEM_STATUS, SESSION_STATUS
FROM V$STATISTICS_LEVEL
ORDER BY ACTIVATION_LEVEL, STATISTICS_NAME;
Hope this helps.
Arup
