DB2 Fixpak 9 now available for LUW

[Mark A]

Also, noticed there is now a separate fixpak 9 for Linux 2.6 Kernel in
addition to the regular Linux fixpaks.

[Buck Nuggets]

unfortunately, it's labeled as fixpack 8 for the aix 5 version:

any idea of how much of an impact the direct & concurrent io tempspaces
will have on warehousing apps?

Can IBM explain why this is necessary, please?

Are you referring to buck's question (which I can't answer) or the
obvious typo (which I have reported)?

I'm referring to the separate FP9 for Linux 2.6 kernals...this seems
very unusual. Will we be thread specific in the future?

Perhaps there is maintenance specific for the Linux 2.6 kernel or
perhaps there is something about the Linux 2.6 kernel that requires
something in the fixpak install to be different. I don't think IBM would
go out of its way to have fixpaks that are thread specific if it wasn't
necessary. But perhaps Serge or Darin can find out more.

The reason is to support asynchronous I/O and vector I/O performance
enhancements that are only available with the 2.6
kernel. I don't believe it is mandatory that you use the special fixpak for
2.6 kernel if you don't need the I/O enhancements (not 100% sure).

The enhancement is described in "New in this Release" section of the Release
Notes. However there is an errata in the FixPackReadme.t xt that comes with
the Fixpack in section: "3.1.2 Correction to the Version 8.2.2 Release Notes
(Linux)."

To take full advantage of the 2.6 kernel on x86 and x86-64 platforms,
we need to compile with a newer compiler. We can also remove checks
for the kernel level from the code - the fact DB2 doesn't crash on
startup implies we're on a 2.6 kernel, and can take advantage of
certain features.

DB2 will continue to be kernel-specific on these platforms for the life
of version 8, so that we can continue to support RHEL3, SLES8, and
other distributions that were supported at the GA of v8.2 (or v8.1).

I cannot speak to what future versions of DB2 will be like.

[bwmiller16]

I would definitely like to know if this is mandatory or not...I'd hate
to install the standard FP9 with our 2.6 kernal only to find out the
hard-way that the special FP9 for 2.6 was required.

Thanks guys,

Bruce

This will likely continue into the future. From what I understand the
main issue is the "gcc ABI" (I'm parrotting I confess). To have a stream
that specifically exploit 2.6 features is a pleasant side-effect.
