Re: [Plug] Oracle8.0.5 for Linux

[Kevin Hill <khill@quarterleaf.com>]

People who ask questions once and learn from the answers become
powerful. 

People who simply repeat their questions rather than learning from the
answers get flamed.  

So far, this list seems pretty intelligent.  Ah well, enough
preaching...

The PDF version of the installation guide outlines the following
parameters for the Oracle SGA:

LINUX Kernel Parameters 
SHMMAX 4294967295 
Note: This setting does not affect how much shared memory is needed or
used by Oracle, or the operating system. It is used only to indicate the
maximum allowable size. This setting also does not impact operating
system kernel resources. 
SHMMIN 1 
SHMMNI 100 
SHMSEG 10 
SEMMNS 200 
SEMMNI 70 
SEMMSL Equal to or greater than the value of the PROCESSES
initialization parameter.

This involves kernel hacking, primarily in the linux/include/asm-i386
and linux/include directories (see sysctl.h and shm.h for ugly details).

However, I didn't do any of that to my default kernel parameters before
installing and I haven't had any problems.  I think this is only
necessary if you're running an Enterprise-scale Oracle instance (GB or
TB database size) and then the SGA modifcations are needed.

My advice: try it without the kernel hack and, if you don't have
problems, forget about the recommendation.  You can always hack and
recompile the kernel later without hurting Oracle.
