Problem Summary: The Sun Cluster HA for Oracle data service uses the su command to start and stop the database. The network service might become unavailable when a cluster node's public network fails.
Workaround: In Solaris 9, configure the /etc/nsswitch.conf files as follows so that the data service starts and stops correctly in the event of a network failure:
On each node that can be a primary for oracle_server or oracle_listener resource, modify/etc/nsswitch.conf to include the following entries for passwd, group, publickey, and project databases:
passwd: files
group: files
publickey: files
project: files
