Hello experts,
I am currently working on the architecture design of an application using SAP BI4 and I am facing an issue with the DRP.
I have two datacenters which are separated (no SAN replication between the two sites, different IP ranges on each site, etc.). The only link between my datacenters allows me to do LAN replication (dataguard, rsync, etc.).
In case I lose my first datacenter, my application must be restored on my secondary site within a day (or less...).
So, in the first place I had thought of the following architecture :
On the first site, one "active" virtual machine (with Apache, SAP BI4 and Oracle as RDBMS).
On the second site, another "passive" virtual machine (same components)
Between the two : Database and file replication
But, a SAP consultor that I met told me that it wouldn't work because of an issue on BO. According to him, when you install BO, the software stores informations about the machine that runs the CMS (such as hostname or IP) in the CMS system databse.
So if you synchronize your database on another machine, you put informations about machine A on the machine B... And then it doesn't work !
Have you ever heard anything about that issue ?
If it is true, backup/restore from one server to another shouldn't work either, should they ? So how would the data loss be secured ?
Anyway, I am very worried about this issue so if you have any idea about how to implement a DRP solution don't hesitate :-)
For about a second, I thought of creating a BO cluster between my two sites but I believe that such a cluster wouldn't be technically possible...
Thanks for your help,
Best regards,
Joël
