Hi,
I am working on Exadata X6-2 1/8 - Oracle Database 12c Enterprise Edition
Release 12.2.0.1.0 - 64bit Production
When I need to drop a plan for a specific sql_id I use it :
begin
dbms_shared_pool.purge ('00000004ED6446C0,394344537','C');
end;
/
My issue is : all sql_id that uses the plan_hash_value: 697333930 are with
long time to finish.
The application does not have a bind for the query (I ask to put it, it is
very important), so each execution generate a new sql_id.
I would like to know how to drop the plan_hash_value , in order to avoid
any sql_id use it again.
Does it make sense ? or when I drop the plan for the sql_id, a new sql_id
will generate a new plan_hash_value that can be equal that one dropped ?
The idea is do not execute :
alter system flush BUFFER_CACHE;
alter system flush SHARED_POOL;
only drop the specific plan_hash_value.
Thanks
Eriovaldo
