I'm having an issue with Oracle OEM where if I use IP aliases on a NIC for a
SQL*Net listener OEM 9i won't auto-discover the instance.
For example :
Base IP set in rc.config = 10.10.10.1 hostname alpha1.xxx.com
IP alias for dev instance = 10.10.10.2 DNS entry odev.xxx.com
Listener config uses HOST = odev PORT = 1522
tnsnames.ora file uses HOST = odev PORT = 1522
Oracle is telling me that in OEM 9i this won't work, that odev must be a
CNAME of alpha1 rather than a separate IP entry.
These systems aren't clustered, but using the IP alias rather than a CNAME
is identical in concept to the cluster alias or service alias in a
TruCluster.
Can anyone shed some light on how OEM 9i would be configured in a cluster to
avoid this problem?
