Hi experts,
Current system info:
server 1 with Redhat 6.5 and Orale ASM with SAP ECC 6 GRID 11.2.0.3 standalone installation
Target system info:
Server 1 and server 2 running RAC 11.2.0.3 with SAP ECC 6 and RedHat 6.5 GRID with cluster
We are trying to convert our current system to oracle RAC but have some doubts.
We are following "Configuration of SAP NetWeaver for Oracle Grid Infrastructure 11.2.0.2 and Oracle Real Application Clusters 11g Release 2: A Best Practices Guide" so:
On page 29 It says: "Prepare the storage location for storing the shared ORACLE_HOME directory in the cluster. The Oracle RDBMS software should be installed into an empty directory, accessible from all nodes in the cluster" Same thing for ORACLE_BASE for the RDBMS, SAP subdirectories (sapbackup, sapcheck, sapreorg, saptrace, oraarch etc.) and homedirectories for SAP users ora<SID> and <SID>adm to a shared filesystem.
1.-Can we just use NFS for sharing them? or what is the recommended software on REDHAT for doing it?
'cause on note 527843 it says:
You must store the following components in a shared file system (cluster, NFS, or ACFS) here it says we can, but down the note on section linux says:
RAC 11.2.0.3/4 (x86 & x86_64 only):
- Oracle Clusterware 11.2.0.3/4 + ASM/ACFS 11.2.0.3/4 (Oracle Linux 5, Oracle Linux 6, RHEL 5, RHEL 6, SLES 10, SLES 11)
Oracle Clusterware 11.2.0.3/4 + NetApp NFS or
- Oracle Clusterware 11.2.0.3/4 + EMC Celerra NFS
It does not mention just NFS.
2.-In our system test, we want to backup all oracle configuration files on file systems and then delete Oracle Grid to Install GRID with cluster option, then install RDBMS with rac option and then follow the guide, is that correct?
