Oracle 9.2.0.3 solaris 5.8 raid 5 T3's I have a server which was created for adhoc purposes. What has happened is this. Instead of users running adhocs, they have created a package which creates tables (all logging of course) based on their adhoc query. The package then uses dbms_output.put_line to write the created table to a file which then ftp's the file to the appropriate client. Roughly 200 reports are written a day and most would be over 1 million lines and total file size would be ~10Gb. Of course everybody wants their report by 9:00 a.m so the box is routinely pegged at 60% i/o wait. So everybody is complaining about database performance. I have stated that dbms_output was probably the worst way to implement this. As I recall dbms_output will write out one line at a time. Now would the use of dbms_output affect other ddl. A truncate of a small table can take 15 minutes. Or is that just a function of the i/o waits? I guess I'm looking for some really technical explanation as to why there performance is so bad.
