If the session can re-connect the message below is displayed then the application can still generally be used without restarting:
Multi-subnet Failover
The following cluster configuration is required for prompt failover of the Synmain application.
Powershell:
Get-ClusterResource "NETWORK NAME" | Get-ClusterParameter "RegisterAllProvidersIP"
eg: Get-ClusterResource "PRDSYNAGMC_PRDSYNLSNRMC" | Get-ClusterParameter "RegisterAllProvidersIP"
The result should be zero (0) for any multi-subnet DB environments for Synmain to connect quickly
Use the corresponding Set-ClusterResource command if required.
Other Considerations
Nodes should share the same hardware configuration, notably drive assignment. If synchronous commit is utilised then the server should have identical hardware for performance. Also need to consider network latency between cluster nodes and failover behaviour, in particular if setting synchronous commit with auto failover.
