I am going to build a DR setup for SAP PI/PO dual split system. As we observed that we could not use oracle data guard to establish the Disaster Recovery site due to some limitations that some file systems also updated during the execution of PI/PO scenarios. So we decide to go for storage based replication. Our OS administrators have configured the storage replication from Primary site to DR site.
Now we need to test our DR site to validate the DR configuration. Any one can guide us how to test the DR system. Do we need to change the configuration on PI/PO scenarios or we can use them as its or we need to re-generate the communication channels after switch over to DR site.
We have maintained the same hostname for both Primary and DR site. Our PI/PO release is 7.5 , database oracle 12c. PI/PO is integrated with Back end ECC 6 ehp8 system and other external systems.
