Good summary of OSWatcher in TFA. Having just installed TFA in daemon and non-daemon mode a nice summary
Some time ago I wrote a post about using OSWatcher for system analysis. Neil Chandler (@ChandlerDBA) rightfully pointed out that although OSWatcher was cool, TFA was the way to go. TFA can include OSWatcher, but more importantly it adds a lot of value over and above what OSWatcher does.
I guess it depends on what you want to do-I still think that OSWatcher is a good starting point and enough for most problems on single instance systems. When it comes to clustered environments, TFA looks a lot more appealing though.
In this article I am taking a closer look at using TFA – which is part of the Oracle 18.104.22.168 and 22.214.171.124. TFA is automatically updated as part of the quarterly patches, which is nice because the default/base release does not seem to be working properly. Thankfully TFA can be patched outside the regular patch cycle.
What is TFA?
