with our interfaces over our SAP PI 7.31 (ABAP/Java) system we assume we will run in a 7x24 h runtime scenario in the future.
Regarding Business Continuity we have to think about solutions which help us to handle downtimes greater than 15 min. regarding Support Package upgrade, Kernel update, EHP, etc.
The first idea is to implement a second equal SAP PI productive system in parallel to the existing one.
On the sender side a switch over implementation like WebDispatcher, Load Balancer, etc.
For maintenance all Interface traffic can run over PI Nr. 1 and PI Nr. 2 can be updated.
Afterward all interfaces will switched to PI Nr. 2 and PI Nr. 1 can go in maintenance.
Could be this as suitable solution for SAP PI Business Continuity or do you know better solutions?
Many thanks in advance!
