Steps to Reproduce
Not Applicable
Root Cause
This behavior is as per Pega product design.
Resolution
Here’s the explanation for the reported behavior:
When a node is added for a DataFlow-Batch or a Stream Server, DSM services start in the server mode:
[StreamServer.Default] [STANDARD] [ ] [ ] (rvice.operation.StartOperation) INFO - Starting service [StreamServer.Default]
[StreamServer.Default] [STANDARD] [ ] [ ] (rvice.operation.StartOperation) INFO - Successfully started service [StreamServer.Default]
[vice: DataFlow.Batch] [STANDARD] [ ] [ ] (rvice.operation.StartOperation) INFO - Starting service [DataFlow.Batch]
[vice: DataFlow.Batch] [STANDARD] [ ] [ ] (rvice.operation.StartOperation) INFO - Successfully started service [DataFlow.Batch]
When a node or service is decommissioned followed by a restart, the same services start in the client mode (this is normal).
[StreamServer.Default] [STANDARD] [ ] [ ] (rvice.operation.StartOperation) INFO - Starting service [StreamServer.Default] in client mode
[StreamServer.Default] [STANDARD] [ ] [ ] (rvice.operation.StartOperation) INFO - Successfully started service [StreamServer.Default] in client mode
[vice: DataFlow.Batch] [STANDARD] [ ] [ ] (rvice.operation.StartOperation) INFO - Starting service [DataFlow.Batch] in client mode
[vice: DataFlow.Batch] [STANDARD] [ ] [ ] (rvice.operation.StartOperation) INFO - Successfully started service [DataFlow.Batch] in client mode
By default, the DSM Services start in the client mode and this does not impact the performance.
