Is it possible to set a varchar2 parameter (e.g. optimizer_mode) in a foreign database session ?

dbms_system seems to lack set_varchar_param_in_session procedure.

Yup.

...not much to say about that :-)

Sorry.

No way ?

Alexei Polozov, November 26, 2015 - 12:18 am UTC

Is there any other way to accomplish that ?

A logon trigger would help, but we would like to modify optimizer_mode and/or to switch some patches off/on of an already connected user.

For a connected session, I think you're out of luck.

I've seen people explicitly code support for this (ie, intermittently check a context variable and take action if its set), but I dont think we can push things into the session directly.
