Ramon,

Why do you consider those values to be "high"? Actually, why did start looking into v$sysstat? Is your system running slow?

Hi gurus,

I started a process and checked the V$sysstat and found those values are extremely high

free buffer requested 28938, enqueue requests 25035. I checked the Tuning manual and incremented the log buffer and add another DBW process.

Scenario Sun 880 Solaris 8, Oracle 8.1.7.3, 8GB Ram, 4 processors

  Redo logs 200MB size 4 groups in 1 disk   DBWriter = 2
  log buffer 200 MB
  Shared Pool 1 GB
  db block buffers 100,000
  db block size 8K
  db block lru latches 2

  Distribution:
  Data 1 volume stripe of 2 disk
  Index 1 volume stripe of 2 disk -- differents   RBS 1 disk apart
  Temp 1 disk apart
  Redo logs 1 disk apart

I AM TOASTED !!!! What parameter should I check ?
Any suggestions, considerations

  TIA   Ramon E. Estevez
