Re: 10g with HACMP (no RAC)?

I have used HACMP in the past with Oracle 8i & 9i on AIX 5.2 (also with EMC
SAN). What do you mean with "the instances will not failover properly" ? I
never had any problems with it, but of course, you always have downtime (in
our case 5-10 minutes) during a failover/failback since the instances have

A and B do not really differ in lines of java code.

A table with lets say 100 columns and 90 % NULLs in each row is no problem
for the database performance and storage?
OK, one could change A in a way that the values are stored natively:
create table ObjectProperty (ID numeric(10), ObjectID numeric(10), Fieldname
varchar2(50), FieldvalueV varchar2(4000), FieldvalueN numeric(30,2),

Hi,
just a few tips.
Make sure that the database VGs are 'enhanced concurrent' or failovers
will be painfully slow. If you want to have fast failovers, set MTTR
accordingly, so that the database will not have to apply huge amounts
of data from the redo logs. Put all the configuration files in your

If you downloaded 9i docs they are valid for 9i
If you downloaded 10g docs they are valid for 10g
Too bad you don't think it important to include a link so we could
see what you downloaded.

And why not Data Guard? First it is free ... Second it provides
transparent failover just like RAC.

Thanks, hpuxrac. I had already found the second of your links, but I've
downloaded the boulder docs and will peruse them with interest.

OBDC with Oracle

diet...@ameritech.net (Dereck L. Dietz) — Sun, 09 Sep 2008 01:30:57 UT

I downloaded the 9i and 10g OBDC software and also the documentation.
However, when I look at the documentation it mentions Oracle8. Does anybody
know if that documentation is even applicable anymore?
Thanks

Thanks for the response, Sybrand.
Two reasons: First, the application vendor does not support RAC, except
maybe as active/passive. But for that the RAC licence cost is
prohibitively expensive.
Secondly, whether we like it or not, the customer is a dedicated IBM
shop (personally I have doubts about AIX being the best *nix platform

In Oracle 10g RAC you don't even need HACMP!
Also Oracle RAC allows for active/passive configurations.

Oh yes it does. They want to use the database as a bit bucket and write
a million lines of Java. Might as well use flat files for the data, and
save on the database licences.
Sorry, I am in a bad mood.
