TCP Ports are Being Allocated Dynamically During Client and Server Communication in ORPOS (Doc ID 1302946.1)

Last updated on NOVEMBER 15, 2021

Applies to:

Oracle Retail Point-of-Service - Version 12.0 to 13.3 [Release 12.0 to 13.3]
Information in this document applies to any platform.


In Oracle Retail Point Of Service (ORPOS), the registers are being allocated TCP ports dynamically when they communicate with the store server.  A couple of common ports are used for initial communication (e.g., 1300, 34779) but after that ports are accessed randomly over a large range (36316-60380).  Specific port numbers need to be known and should be configurable.

Steps to Reproduce:

  1. Start the POS client and server.
  2. Observe random port allocation using a network tracing tool.
