Question on Oracle SCAN Name and RAC Host Migration
Hello,
I have a situation where we need to migrate a 2 node RAC Cluster running Oracle 11gR2 (11.2.0.2) Clusterware and RDBMS into a new set of machines (OS platform and GI & RDBMS versions remain same). Currently all applications are using the hostname 'prod-scanip' in TNS settings or JDBC urls to connect to the database. The SCAN name 'prod-scanip' resolves into 3 IP addresses (SCAN IPs)from our DNS. The shared filesystem is an NFS volume from a NetApp filer mounted on both nodes. The OCR and Votedisks are also on these shared NFS filesystem.
We were thinking of an approach to setup a new 2 Node Cluster with Oracle 11.2.0.2 with the latest PSU (both GI and RDBMS) having a new scan name - same shared NFS volumes will be used on the new machines for Vote Disk and OCR, but different locations will be used for OCR and Vote Disk - then to migrate production onto the new machines:
