Hi, all,
I believe many people are running oracle 9i on solaris platform.
Does anyone noticed this message while starting oracle instance at
solaris:
"Wed Dec 15 21:00:06 2004
Oracle instance running on a system with low open file
descriptor limit. Tune your system to increase this
limit to avoid severe performance degradation.
"
According to metalink, os parameter "open files" (rlim_fd_max at
solaris?) need to be tuned as formular: 2*db_files +
controlfile+logfile ..., if my db_files=1000, then I have to set
rlim_fd_max to near 2400. Without changing this parameter, will there
really be some performance degradation?
If I reduce the db_files to 100 or so, then no warning any more.
Thanks.
