Digital Unix V4.0f

The product name Digital UNIX has recently been changed to Tru64 

UNIX. However the Adaptive Server IQ documentation still uses the old 
Digital UNIX name.

The following operating system command shows the level of your base system

Tru64 UNIX V4.0D  (Rev. 878);

Wed Jul 15 12:31:49 EDT 1998 

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.

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.
