Home -> Community -> Mailing Lists -> Oracle-L -> RE: INSERT...SELECT pegs CPU, but is waiting on scattered read?
If you can still connect to Oracle, you'll probably see a tremendous
amount of activity reflected in V$SESS_IO.BLOCK_GETS and
~.CONSISTENT_GETS. Cut the SELECT statement into a SQL*Plus session and
go to work on "tuning the SQL." This (a SQL tuning issue) is almost
undoubtedly the cause of your problem.

To make matters worse, the process is completely hung now, being 100%
CPU
bound with zero I/O:
It's been sitting here now for 15 minutes (more?) in a tight CPU loop.
Joy.
