MAA for OEM

Question

I was reading the white paper on Maximum Availability Architecture for OEM, everything is pretty clear for one portion and I need to get clarification:
1. For repository, we can use Data Guard,
2. SLB, we can have global SLB so one site goes out, the other will pick up the work
3. OMS: Oracle recommened to use Share Loader Storage for both site, this throw me off a little b/c where is the Share Loader Storage will be physically located? Obviously, it had to locate on one site, what if hurricance hit that site and wipe out Shared Loader Storage?
Has anyone implemented this architect before?
Thanks

Answer 1

Please describe in more detail your planned setup. For example
Main Site
   SLB
   OMS 1
   OMS 2
   Shared NFS
   OMR
      RAC Node 1
      RAC Node 2
DR Site
   SLB
   OMS
   OMR (Data Guard)
1. For repository, we can use Data Guard, Yes
2. SLB, we can have global SLB so one site goes out,
the other will pick up the workYes
3. OMS: Oracle recommened to use Share Loader
Storage for both site, this throw me off a little b/c
where is the Share Loader Storage will be physically
located? Obviously, it had to locate on one site,
what if hurricance hit that site and wipe out Shared
Loader Storage?The shared loader storage should be in your primary site. If you are implementing a Global Load Balancer then you need to make sure that this is also replicated to the DR site.
I think what you have described is;
SLB
   Main Site
      OMS 1 (Active)
      Upload (Some file system)
      OMR
         RAC Node 1 (Active)
         RAC Node 2 (Active)
   DR Site
      OMS 2 (Active)
      Upload (Replicated files system)
      OMR (Data Guard, Physical Standby)
Is this correct?
