No performance activity monitored in Enterprise Manager. EMN0 process blocked

NuGlamSMSApr 8 2015 — edited Apr 13 2015

Hello folks.

I have many Oracle 10.2.0.5 over HP UX added to an Enterprise Manager 12c.

From time to time I realised the Top Activity option from Performance Menu is not drawing anything, the graphic is empty. The rest of the database is running fine. So I have to kill the EMN0 process from operating system and then automatically It starts again to work, the graphic is drawing the activity.

I don't know the reason of that, what's happening and if this is the right action.

I've searched with no success.

Anyone have any idea that could help me?

Thank you in advance.
