One of our customers face the problem that the takeover of a Hana database sometimes takes more than 35 minutes.
Environment:
Hana 2 database, size abouzt 1,25 TB, 192 CPUs, 6 TB RAM
Two system replications (A-B and B-C, A-B is synchronous, B-C asynchronous)
When doing a takeover of the B-C replication, the time taken varies from 5 minutes up to 50 minutes ehich is too much as the required RTO is 15 minutes.
What can be the reason for this effect?
