Can I get 1,000 concurrent users on a sparc/2000 (Solaris) w/5gig mem
and 20 85mhz processors running Financials and some home grown Oracle
apps (PL/SQL, Pro*C and ODBC) (Oracle 7.1). We also have an SQL*Net
client computer sparc/2000 w/2gig mem and 8 85meg processors.
We have this configuration and have found the machine to be I/O bound
(the system shows about 40% wait-I/O at any given time, resulting in
some pretty horrible response times). We 've pretty much exhausted
all of our resources trying to get this to work (i.e. more memory,
more cpu's, ...). We are now in the process of reworking the
applications (but that will take time). The one thing we haven't done
yet is set up raw devices for the Oracle database files. Will this
give us much improvement? My guess is yes, but the powers-that-be say
no? They are now looking into trying different hardware (i.e.
something other that Sun).
We've had people from Oracle and Sun looking at our configuration, but
they haven't offered much help (they actually made things worse in
some cases...).
Can anyone offer any advice? Is anyone running this at a site with
this much hardware and this many users?
Much thanks,
Tom
