- 17. © 2015 Cognizant17 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
