I have just been back into 'services', and the performance logs& alerts was not started. I am sure I started it the other day[ See an earlier post], so I have started it again we shall see what happens

Thank you. done. do you think that may do the trick. cheers

Well that has not cracked it. LH and scott what do you think of my observation that RAC_PS is disabled in start up event session, and does not appear in event session, also in SYSTEM LAN diagnostics,System diagnostics, System performance and wireless diagnostics are all stopped. These things mean nothing to me, but may to you. The link that scott gave me earlier showed an example where RAC_PS was Running in event session

I have just found this thread which appears to have solved my problem for some but I dont know how to do the middle bit of creating full control permissions for the local services.
I can reset RAC ok. I tried ignoring the bit about permissions, and opened the command prompt but when I type in RACAgent and press enter nothing happens, anyone explain in simple terms how to do the permissions bit, as when I go to security tab I am lost. thank you

Thank you so much LH, I have done that, and EUREKA, I have a display on my reliability monitor. It has gone back to21 june, and shows up to 25 june and going no further at the moment, but I assume I may have to wait a while until it displays up to date. thank you very much this has been quite a saga and I have learnt a lot, but hopefully we may have cracked it, or am I being too optimistic cheers

Just logged On again and it is already up to date. I dont know who or what Trin is, so I guess thats a no. i am long since retired and a late newcomer to the computing world. thank you again

So you can guess what my second name is now. cheers
