Hi Colleagues,
I have a requirement to implement a High Availability for ECC on Solaris server. We are running ECC on HANA with distributed installation (ECC on Solaris, HANA on Linux). The High Availability on the HANA side is already taken care of. I would like to know the HA configuration option for the ECC. We will be installing Primary application server (CI) , ASCS, ERS and 3 Additional Application servers (Dialog instances) All of these will be installed with Virtual IPs on Solaris.I am interested in knowing about HA configuration options. As of now, Our plan is to install ASCS on node A and ERS on node B of a cluster with fail over configured for the SPOF components.We also want to configure failover for the CI and Dialog Instance, as we do not want any user sessions (work processes) to be cancelled when any of these instances fail. For this, Is it possible for me to configure Virtual IP based failover of the CI and Diolog Instances from the Production to Quality so that when the Prod failsover to QA, the QA will shutdown and be used for Prod? I would like to know how this kind of configuration works. How can QA be configured such that it can be used for QA as well as a passive node for Prod failover? I would like to know the high-level of how this process happens and how the filesystems and networks are configured for this to happen. Could you please shed some light on this topic.
Thanks!
Veera
