your post lacks your currentkernel patch level and the installed release. Maybe you have already installed 112233-12 or even a more recent release of Solaris 9. E.g. Solaris 9 4/04 has the initial kernel patch level 112233-12 or Solaris 9/05 kernel patch level 118558-11.
Use uname -a and cat /etc/release to obtain the information.

Added information regarding initial kernel patch levels.
118558-33 was obsoleted by 118558-39 on 11 Jan 2007. I would recommend to visit the [*Oracle forums*|http://forums.oracle.com/forums/main.jspa] and/or the contract-customer-only patch forum (this is a [*link*|http://blogs.sun.com/patch/entry/patch_forums_now_available_for] to an blog entry describing a procedure to access this "private" forum).
I don't know if it's save to apply the latest Solaris 9 patch cluster. You can use updatemanager or PCA to install missing patches.
