moving non system segments
First of all, that "hc.sql" script is *really* old,
not well written, and liable to produce all kinds of absurd advice.
Please take *anything* that it says with a large grain of salt (at least a grain
large enough to be a salt lick for a herd of deer). Even Mr. Kolk's
extremely well-planned and well-written YAPP processor occasionally produces
some amusingly irrelevant bits of advice at times...
Having said that, the ALTER TABLE ... MOVE command
on "heap" organized tables will certainly cause an issue with access. To
wit, you can't. So, you have to plan on downtime for those objects
while the MOVE is occurring. And don't forget to rebuild the related
indexes after the MOVE command finishes. Luckily, I have a
"gen_rebuild_idx.sql" script to help with that. There is an ALTER TABLE
... MOVE ... ONLINE command for index-organized tables and ALTER INDEX ...
REBUILD ... ONLINE command for indexes which do not have access issues,
As far as the objects that the script pointed out
as incorrectly residing in the SYSTEM tablespace, I wouldn't really worry about
them unless you are actually using the features that rely on them. I think
MDSYS has to do with the "spatial" option, ORDSYS has to do with "Inter-Media",
and I forget what those other schemas with the dollar signs are related to, but
I'm certain they have to do with some Oracle salesperson's
children's orthodontist bills. That CSMIG schema looks quite
non-Oracle and non-standard, but I could be wrong, and that SYSTEM schema is
usually quite harmless as well. It all depends on whether those features
will be used or not -- if they will, then move to some other
I'm glad that you like the script, but it is the
one that I think most about removing, mostly because it has aged rather worse
than I. I've been thinking about rewriting it and bringing it up to date,
but other things always get in the way...
Hope this helps...

Subject: moving non system segments
I was playing around with Tim Gorman's hc.sql (health check)
and would like to move these objects into the USER
tablespace. I would like assistance in
additional things to consider.
