Hi everybody,
one million dollar questions ;-) aka transition to cDot could be really a nightmare! The questions come not only from best practice and TR I've read (or I could read...) but your ideas about best ways to bring in cDot what now is deeply optimized in 7Mode.
AS is - 7 Mode A lot of NFS volumes where to separate data/log/temp of each Oracle instance. Each volume is exported for access only to the hosts that manage binaries and db. In the production environment all instances are RAC while in development test most of them are RAC but some are also composed just by one server. 90% of hosts are VMware VM, some are phyical for RAC instances composed by a phys-virtual pair of hosts. Volumes are hosted on aggregates composed by SAS or FC discs depending on type and importance of workload. In test/dev there are mostly SATA vols but non only. Of course, all the instances are managed and replicated with the concurrent usage of Snapcreator and its integration with DFM Protection Manager that it's then integrated with Snapmirror
To be - cDOT (8.3.1) <- we hope to be able to use SVM DR features somewhere... Each instance in a its own SVM? This could be a nightmare to manage ipspaces, dedicated lifs, flexvol that once assigned are locked to that SVM and so on.... Just one SVM for all NFS RAC? Maybe creating differente FlexVols with qtree for data/log/temp? Or on different aggregates? One or more SVM, few, just to balance the workloads between controllers? Is there an advantage offered by the juction paths that should be created?
Every idea is accepted also is recently has been demonstrated that brainstorming is useless :)
