Sorry you feel that way.I thought I was nice to the FDR people,
myself. After all at least you are upfront about who you work for and
the information is almost always balanced. Its the marketing people
who I now tend to distrust. You still have your reputation..
Ed, I was kidding (a little). Since you stroked me <gr> here goes
There are a couple ways to erase a track.
- there is an ERASE CCW, which erases all or part of a track. The
actual action of ERASE depends on the manufacturer (some overwrite the
track, some just make the existing records inaccessible). A separate
ERASE is required for each track, but they can be chained together
- on 2105 and above, there is an ERASE function in the LOCATE RECORD CCW
which can erase multiple tracks (up to 16) with a single CCW.
- you can overwrite the track with data, using a regular WRITE CKD.
Again multiple tracks require chained I/O.
The system "erase on scratch" function (a RACF attribute which can also
be requested on a IDCAMS DELETE CLUSTER) just uses the ERASE CCW, one
track at a time, to be best of my knowledge (we did trace it some years
ago). Not very efficient which is why it is rarely used.
Our FDRERASE product, as you might imagine, supports all of the above
options, in the most efficient manner possible. The ERASE CCWs (which
we call QUICKERASE) does make the data inaccessible but does not meet
any government standards. Our ERASE and SECUREERASE functions overwrite
the track and SECUREERASE complies with US DoD standards, which is why
those functions have been certified by the US government under Common
Criteria.
BTW, on the articles, I think you are a little shortsighted to dismiss
such articles out of hand. Although they may have been written or
sponsored by a vendor to spotlight their product, they may still include
valuable info on the general topic. I can't speak for other vendors,
but for Innovation I can tell you that such articles are carefully
vetted (often by me) to insure that they are factually accurate. Of
course, we want to present the product in its best light, but we never
exaggerate or (gasp!) lie. So I suggest you mine such articles for the
valuable facts, just keeping in mind the source.
