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 greatly appreciated, Kind regards, Michael -- This message posted from opensolaris.org _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
