Howabout , the following but I am sure you have looked at that already

PROMPT ================================================================

PROMPT Redo Log Space Requests

PROMPT Should be near 0

PROMPT If greater, increase 'log_buffer' parameter

select name, value

from v$sysstat

where name = 'redo log space requests'

/

Subject: SQL for Monitoring; log_buffer entries/growth?

 

Got any SQL for me?

Want to monitor how the log buffer entries are reacting / growing.
What is best to see how the buffer is performing or log buffer activity?

SELECT name, value  FROM V$SYSSTAT WHERE NAME like 'redo%' ???
Specifically "redo buffer allocation retries" ???

PS I know I have activity as we are archiving like crazy during heavy
load.

Thanks in advance.
