Hi
I am not 100% sure if the symptoms match because the last_analyzed for
those stale stats tables are from a few days ago to a few months ago.
However I am planning to apply the patch for bug 31464691 due to
other issues (mentioned in 2448781.1) tomorrow, I will see if it fixes this
issue and let you know.
Thanks

Isn't this the bug documented below
*Statistics for All Tables Getting Stale With No Data Change in 12.2 (Doc
ID 2448781.1)*
- Data has not changed but many objects have stale statistics

statistics
Hi all
I am running 19.10 8 nodes RAC database with Multitenant. I noticed that
after running DBMS_STATS.GATHER_DICTIONARY_STATS in the PDB I still see
tables with stale statistics under SYS. For example:
exec DBMS_STATS.GATHER_DICTIONARY_STATS
SQL> select count(*)
2 from dba_tab_statistics
3 where STALE_STATS = 'YES'
4 and owner = 'SYS';
COUNT(*)
----------
305
Anyone seen this behaviour?
TIA
