Yes you are right, sorry but I made a mistake, since we are using = Baan IVc4 which works against Oracle we have no means to interfere with = its transactions when they are commited to Oracle and we can not modify = them so that it uses a specific rollback segment, so the only way for us = to do it is to disable all except the one we want it to use.

set transaction use rollback segment xxxx only works if it's the first =
statement in your transaction, an easy way to make sure this is the case =
is to issue a commit directly before issuing this statement.
I believe this has been a feature of Oracle since way back in version 7 =
(Correct me if I'm wrong).

Hope this helps.
Cheers

Which database version are you using? as long as I know, at least on =
Oracle 8.0.6 you can not specify which rollback segment a particular =
transaction should use. We disable all rollback segments and only enable =
those which we know won't make big updates / deletes crash.

Hi Friends,
=20
I have 150Gb database with 30 rollback segs with optimal settings!! for =
normal operations no problems!! But we are doing massive updates for =
some of big tables!! So we are using vb programs and connecting to the =
database thru odbc dsn. My first question is how to set transaction use =
rollback segment rbs_big? I tried to set as first stmt, but its not =
using rbs_big segment, its using some other rollback segment. Is that =
good idea to make all my rollback segs maxextents unlimited to avoid =
maxextents reached error?? I have lot of rbs space nearly 10Gb. I saw =
one time, one of my rbs segment extented 2gb and failed transaction with =
maxextents reached with 5m initial and next, minextents 20 and optimal =
100M.
=20
Any help will be appreciated
Thanks
venkat.
