What value to use for filesystemio_options when using both UFS and ZFS?"

edited Sep 22, 2010 8:00PM in Database Administration (MOSC) 1 commentAnswered

Database 10.2.0.4
OS Oracle Solaris on SPARC (64-bit)

We have been doing performance analysis on a new hardware configuration that will go into production in the very near future.

Based on the analysis we found out that performance was better when we were using UFS mounted with the forcedirectio option for the online redo log files.

We are running ZFS on the file systems for the data files.

What is the best value for filesystemio_options in this configuration?

  • asynch
  • directio
  • setall
