RE: Question about UDB on iSeries

John,

It is true that DB2 comes bundled with i5OS, and that it is tightly
integrated into the base OS.  This integration has been a fundamental
feature of this platform since its inception as System 38.  Over the years,
IBM has ported many of the newer DB2 technologies from the UDB products into
the iSeries database engine.  I'm not sure if IBM considers DB2 on iSeries
to be part of the UDB family yet...

There are extender products for DB2 on iSeries for specialty applications
like data warehousing (BI), or multi-system clusters for distributed
database, or DB2 SMP for multi-CPU systems which extends parallelism.
Unless you need these features, there's no additional software needed.
Performance monitors are built in, as are reorg tools.

Subject: Question about UDB on iSeries


Please keep in mind that I know **ZERO** about the iSeries and UDB. We are
considering a conversion from z/OS on zSeries to i5OS on iSeries. The
company doing the presentation basically said that everything that we need,
with a few exceptions, is integrated into the i5OS on the iSeries. In
particular UBD is integrated (so we don't need to buy it). But I was
wondering if any iSeries people out there have an opinion about the lack of
requirement for any extra software to support UDB on iSeries. Such as
performance monitors, reorganization utilities, anything at all? I'm
confused (as usual) about why UDB on iSeries does not require any such
software while it appears, to me, that DB2 on z/OS really requires a lot of
extra cost software. This is the whole reason that we are considering this
conversion. z/OS simply requires too much extra cost software compared to
other platforms.
