i want to know the update packages that i have installed on my solaris 9
If you are talking about patches ...
patchadd -p
Solaris (as opposed to OpenSolaris which I cannot speak for) uses patches rather than updated packages, so you run "showrev -p" on the system to list the installed patches and you may use a tool called patchdiag (alternative are available) obtainable from: Product Downloads with a file from Sun called patchdiag.xref, patchdiag then tells you which patches are up to date an which are not (patchdiag will report out of date patches for packages you do not have installed so it is not very intelligent!)
