Home -> Community -> Mailing Lists -> Oracle-L -> RE: RUPD$_ (long)
Amarillo is still beautiful.. although the natives don't seem to share my enthusiasm.
Yeah, I found this... I was just hoping for... more. I can find considerable stuff on mlog$_<> tables, but I'm still digging on this one. I love the 'documenation' on some of these 'features'.
Thanks

April,
How's Amarillo lately? ;-)
The only useful thing I found was on metalink forum (I'm sure you've
seen it) pasted below. Looks like a special log for UPDATABLE
SNAPSHOTS, which would make sense in the context of 2 way replication.

Hi,
could somebody explain to me what's the funcionality of the RUPD$
tables and when they are created ?
The chapter covering the creation of snapshot logs also states the
MLOG$ tables only.
Familiar with ORACLE version 8.0.5, i know the MLOG$ snapshot log
tables only.
I went through the 8.1.7 documentation, but i did not find any
explanation, just a short remark about looking for 'temporay updatable
snapshots' by checking the existance of these RUDP$ tables.
Additionaly i did not find any comment on these 'temporay updatable
snapshots'.
Kind reagards

Hi,
is it possible to get a more detailed information on this?
Are these tables created per default during snapshot log creation
or does the creation of these tables depend on some settings, which can
be disbled or ...
What happens if they are deleted for example, does it then influnece
the behaviour/functionality of fast refreshes?
The current environment is a ORACLE 8.1.7 database server used as
master of updatable and read only snapshots for several
ORACLE Lite clients, both running Windows NT.
Kind regards

Interesting. This topic seems to come up every now and then and I'll refer others back to your findings.
