That single-instance PDF has apparently been pulled down from Oracle’s site… there seems to be an 11g version up now:

I got it years ago from lazydba, I think it was from a guy named Kirti. I cron it every 5 minutes and it works like a charm. It was pointed out that it wouldn't catch an alter system enable restricted session, which I'm not too concerned about. Just last week the script caught a listener hang bug sqlplus -silent < /tmp/$$.1 a/a@${DBNAME} exit; EOF egrep 'ORA-121|ORA-01034' /tmp/$$.1 > /dev/null if [[ $? = 0 ]] then mailx -s " ${DBNAME} is not accessible - db is down" ${MAILLIST} /dev/null if [[ $? = 0 ]] then rm /tmp/$$.1 exit 16 else mailx -s " ${DBNAME} is not accessible - db is down" ${MAILLIST} < /tmp/$$.1 fi fi rm /tmp/$$.1 exit I use this script on all databases I monitor.

I wish it should have been stated as

Since it is Oracle BPEL PM that connects to the FTP server… :)

But then that is confusing because Oracle Unbreakable Linux used to be a support program. Now it is synonymous with Oracle Enterprise Linux: http://www.oracle.com/technologies/linux/ubl-faq.pdf http://www.oracle.com/technologies/linux/index.html So I take this to mean this if you have Oracle Entperise Linux you can use CRS to provide HA for anything you'd like. As for the affect this sort of stuff has on Veritas, they are not alone. Oracle wants in this space and they appear to be serious. Oracle takes a "co-opetitive" stance towards other players like Veritas, Steel Eye, PolyServe, etc. Matt,

It's interesting how the mind plays tricks - I'd actually read that exact verbiage or equivalent from Oracle licensing (possibly in response to a TAR I opened), but interpreted it at the time as "if the box you're using is licensed for Oracle then go nuts" - I somehow missed the piece with just having it be one node in the cluster. As you said, unclear clarity. Not to mention, another situation where Oracle is aggressively trying to take revenue away from a partner company to help justify its own price point. It just very often seems to be poor Veritas/Symantec that's getting the short end of the stick.... Well, we ARE friends, Kevin, not just cause we’ve had beers together.
