CPU always busy in 9.2.0.1.0 on Solaris

CPU always busy in 9.2.0.1.0 on Solaris

 

  



Mateys,

I get a Sun machine running Oracle 9.2.0.1.0 on SunOS 5.9 Generic 112233-02
August 2002 with 4 CPUs.

However, all CPU is busy all the time. Ideal is Zero !!! And the CPU spends
about 35% time in doing system job instead of Oracle job (users). Is that
normal ??? I don't think so. Anything I can tune or investigate this problem
???

oracle => iostat 3
tty sd0 sd1 sd6 sd45 cpu
tin tout kps tps serv kps tps serv kps tps serv kps tps serv us sy wt

Could you please help to to recover my UNDO Tablespace
datafile for my DB which is running in NOARCHIVELOG
mode?

Thanks
