I've recently upgraded NPM from v10.0 to v10.1.2. My Hot Standby Engine v10.0 keep stalling every few munites. I understand the HSE is being replaced by Failover engine, I haven't had time to do the upgrade yet. The FOE replacement product seems to take a while to setup and configure.
I just wonder has anyone upgraded NPM to v10.1.2 and the Hot Standby engine still working?
The HSE is no longer supported in v10.1, so you will need to look at changing over the the FOE solution.
While this is more complicated to setup and install, it is a much better solution for dealing with a failure on the primary server and gives you a full and proper DR installation.
