Eva,
the spin_count parameter became _spin_count in 8i. I believe that because it's a hidden parameter it's now not possible to change it using "ALTER SYSTEM". Regards,

Hello Guru's

I have run a script which indicates that of the three redo log latches two had occurences of sleeps. To overcome this usually you increase SPIN_COUNT by 50% or so.

When trying to ALTER SYSTEM SET SPIN_COUNT = 3000; Present system is set as 2000. I get the following error. *
ERROR at line 1:
ORA-25138: SPIN_COUNT initialization parameter has been made obsolete

Now what? what can I do to overcome the sleeps issues?

Regards
