    Hi,

    This FAQ is somewhat (1) outdated and answers are closer to (2) marketing material than technical documentation.

    Examples:

    (1) "Once I upgrade to Release 12.2, can I still apply patches in the traditional way?

    No. All patches for Release 12.2 will be online patches. The traditional, pre-12.2 method of applying patches will not work."

    -- Well, this is luckily not true as we have hotpatch and downtime apply modes which are both used on the Run system. This is a great feature as for a patch which applied in one hour on 12.1 now with the stopping/starting and adop overhead takes less than 2 hours instead of nearly 24 hou
