The Informatica mechanism of dynamic port allocation across pre-defined ranges has been carefully designed over a multi-year period to handle a wide range of scenarios. There are several benefits to this design:
Dynamically assigning the port number upon service startup means that users do not have to manually assign port numbers to the services they create.
Setting the range of port numbers gives users the flexibility to set the range to a desirable size.
Limiting the dynamic ports to a specific range of numbers allows the IT team to efficiently troubleshoot issues.
