RE: perl/shell script for alert log

Yeah, I log those. Some of the db's I support run with very small redo logs and I can't change. They get those quite frequently at times so I pretty much ignore them. My script also reacts (log,email,page, or run some script) in the event of startups, shutdowns and alter database structure. It also sends everything through a filter of "known" patterns and anything that is not recognized falls out. I call this the paranoid switch "-p". One best practice I recommend is to automate control file backups anytime a ALTER TABLESPACE, ALTER DATABASE etc...is in the alert log.

Hi!

I would add a check for "Checkpoint not complete" in alert just in case as well.
