What views of $ v can I use to monitor the parallel process?

Hi all

The version of DB is 11.1.

I ran a sql in parallel. And I got the SessionID for the session.

But when I referred to v$ px_session, v$ px_process or sql_monitor $ v even with this session id, I have nothing from these points of view.

The exectuion plan showed that it used parallel exectuion.

Could someone tell me what is the problem with my approach? Or it means that my sql has not used the parallel at all?

Best regards
Leon

PARALLEL_MAX_SERVERS to 0 for the database instance. Confirm that there are no PX processes running on the instance of database (these would be process "ora_p0xx_SID", where xx is 00 to 99 (or 128)) on the server.

Then set PARALLEL_MAX_SERVERS to 8 or 16 or more.

Run your query/dml.

Now, see if the ora_p0xx_SID process has created.
