Peoplesoft on Federated UDB?

Anyone using Peoplesoft on a Federated UDB
(shared nothing)Environ ment on Open System Platforms?
Preferably AIX, but any war stories would be good.

edition) or Informix XPS. And it happened before 1990.


Gamma happened way before 1990 too-- the article is the final archival
paper describing the system, probably submitted in 1989 after a 5 or 6 year
project. Teradata may have had a shared-nothing parallel DB before that,
but it is hard to tell exactly when Teradata began to be shared-nothing--
I think their first incarnation was not shared-nothing. But you are correct
that Teradata may have been first. I also think in the 1980's the Teradata
machine declustered relations to multiple nodes for parallel query
evaluation, but I don't know if they supported parallelization of joins of
individual buckets at that time.

Now you're talking man. It's not yet the 30th indeed.
Not sure what's to brag about <60% scalability on that RAC result though.

Teradata was definitely the first to develop a parallel database and by
definition it needed to be share nothing because SMP was available except on
a mainframe. Teradata used Intel nodes with a proprietary operating system.
Teradata used a share nothing architecture (one partition per node) up until
about 1996 when they began to support SMP machines on one or more nodes. Of
course, like DB2, one can still implement Teradata in a share nothing
architecture, but it is usually most cost effective to have multiple
partitions per SMP node, with multiple nodes.

I don't know what you mean by parallelism of joins and individual buckets.
But Teradata in the mid 1980's worked pretty much the same way DB2 does
today (at a conceptual level). The table was spread across multiple
partitions based on a hash key, and each partition processed the data in
parallel. Cross partition joins were supported.

Anyone getting only 60% scalability with RAC needs to take the class I
teach. They are missing something essential.

Add every person that's ever tried to scale RAC over 16 nodes. Daniel,
you're going to be a very rich man!

I'll take you up on it. The class is free if after taking it you can't
scale more than 20 nodes at greater than 80% provided you follow the
steps we teach in the class.

Still, I stand by my point - oracle is a breeze to install, all those
problems of mine could have been easily resolved by additional
training. Right now I'm lobbying for a couple of weeks of training
each year to keep up on these issues so that I won't make the product
look bad. Wish me luck!

Buck

You need training to install it?
And it is a breeze to install?
Looks more like a hurricane to me :-)

What would the scalability be at 128 nodes? 60%?
