Hi Tanel,

FYI, i stumbled upon a new MOS Note warning of an issue on HP with oradebug short_stack.

Process Hangs After Issuing Oradebug Short_Stack on HP Platforms [ID 1271173.1]

Obviously, there are patches for the issue.

Regards,
Martin

You should modify “SET TERMOUT OFF FEEDBACK OFF” to “SET TERMOUT OFF FEEDBACK OFF VERIFY OFF” in ostackprof.sql,line 46

After UKOUG masterclass, I am proud to say that you are %100 genious. According to me, yours was the best technical presentation in Server Technologies category and I can easily say it was the longest end session, applause period I heard :)

The way you add to many dimensions to my future troubleshooting experiences was amazing.
Thank you for sharing your knowledge with the community.

I hope I will be at your seminar in London, I really dont want to miss it.

@Kurt

Yeah, VBScript is “the right tool for the right problem” in this case. No matter how clever the perl/python/awk script is, you won’t get around the fact that you likely need to install additional software on windows workstations to get it running.

@Surachart
Thanks!
