INTRODUCTION
The port number for the Data Wrangling Service i.e., the MJRefSvr_64 Refine Server process is user-configurable. In older Strategy versions (before version 10.11 and 10.4 Hotfix7), the process used the default value of 3333 and was not configurable.
This feature will be useful in Strategy deployments which are not able to use the port 3333 for administrative or security reasons, increasing the usability of the MJRefSvr_64 process.
The port can be configured through a registry setting in Windows environments or by editing the MSIReg.reg file in Linux/Unix environments.
The following factors need to be considered before setting a port for the Refine Server process:
If the registry/MSIReg settings are not changed at all from the out-of-the-box values, the process will use the default port value of 3333.
