Adaptive Server IQ 12.4.0 has been built to take advantage of certain
performance features found in the Digital Alpha EV5.6 (21164A) and later
chip architecture.
1.1 Required Operating System Patches
You must install the patches listed in this section to run Adaptive Server IQ on
Digital UNIX.
• Digital UNIX V4.0d requires the March 1998 patch kit as the absolute
minimum.
Normally, it is best to install the latest patch kit. However, as of Adaptive
Server IQ 12.4.0 certification, the latest patch kits contain a problem in the
pthreads library which causes a one to two times performance slowdown in
Adaptive Server IQ, most notably in loads and multi-user activity. For this
reason, you should avoid using those patches and use the previous patch kits.
The following table shows you which kits to avoid (the middle column) and
which you should use (the last column).
This problem should be resolved in the next release of these patch kits.
