Oracle Database Appliance X4-2
Pre-build system comprising hardware, software, storage
and networking
Node 1 – 2 x 12 cores Intel Xeon processer – 256 GB RAM
Node 2 - 2 x 12 cores Intel Xeon processer – 256GB RAM
Storage Shelf – 20 2.5 Inch HDD & 4 SSD 18TB raw, 32TB doubled-mirror or 21.3 TB tripled-mirror Optional storage expansion with additional storage shelf
Virtualized ODA uses Oracle VM
Servers
Contains 2 X4-2 Oracle Sun Server and a DE2-24P storage
shelf with 24 disks
Can be used to deploy Oracle Databases and other
application such as OEM
One Database domain (ODA_BASE vServer) are created out of box on
each node in Virtualized ODA
Additional vServers are created as
needed
Licensed as needed
2,4,6,…. 36 cores per server

Challenges – Drivers for our Migration Approach
Preservation of historic data of OEM
Avoid rediscovery of targets
Avoid redeployment of jobs
Lack of High Available OEM
Require failback plan
Limitation with solution-in-a-box
Limited downtime for migration
Required lower life cycle OEM environment

Cognizant’s Solution Approach
OEM Migration Flow
POC
Downtime Start Reconfigure Existing OMS
and OMAs to F5 single IP/URL
Downtime End
Add 2nd OMS on ODA VM
Create Standby DB on ODA for existing OMR
Downtime Start Switchover
OMR DB to ODA
Add 2nd instance of
OMR
Re-enroll Additional OMS to New Primary
OMS
Migrate Primary OMS to ODA VM (Backup/
Recovery)
Repoint OMS to new OMR
Downtime End
Configure and build Guest
VMs
Install & Configure
Virtualized ODA
Configure F5 with ALL OMS IP

Key Learning's and Takeaways
ODA
• Multiple VLANs can’t be configured out of box in ODA using firstnet
• Use oakcli create vlan commands
• Suboptimal File system performance when ACFS mounted over NFS on ODA VM
Presented file system as block device to VM
Local storage of physical node could be used as repository to achieve greater performance
But with that no HA to VMs
Use SSD based disk group for database redo
This helps to improve overall database performance
OEM
• No documented migration path
• Combined process of adding 2nd OMS and Restore and recover of 1st OMS
Admin server Migration –documented in recovery documentation of OMS
• F5 persistence setting
• F5 trusted certificate issue
Instead of SSL termination on F5, OEM requires SSL handshake
• Linux native Rsync instead ACFS replication
• Alias of primary hostname are required on DR OMS
• “Solution-in-a-box” template – file systems not extendable
