DBWR write performance
I''m an Oracle DBA, a dtrace noob, and I''m attempting to resolve an Oracle write performance problem on Solaris 10, Oracle 9iR2.
The Oracle DBWR processes have poor write throughput writing to VxFS files. I suspect that the problem may be with POSIX readers/writer file locking.
Ideally I''d like to identify, for a given DBWR process, readers/writer file lock contention on a datafile by datafile basis.
Any guidance would be great...
