Be aware that there can be deviations from the port mappings described above, e.g.:

  • If more than one indexserver is installed in a single instance, it will have port number 3xx15 (, 3xx18, …).
  • For MDC specific details see SAP Note 2101244 (“Why do we see indexserver port other than 3<InstanceNr>03 on tenant databases?”).
  • For smart data integration (SDI) specific details see SAP Note 2511196.
