2552639 - Spurious messages "Warning: Unknown parameter" on several config parameters - SAP ASE

Symptom

  • When downgrading ASE SP03 PL0x to SP0x PL0x
  • ASE reports messages about SP03 configuration parameters still being present in SP0x configuration file after downgrade
  • Mostly, these messages are spurious, when checking the config file post-downgrade, these parameters are not present.
    • In a small number of cases, the post-downgrade config file did show the (now invalid) SP03 lines
  • ASE log records includes message like below
    • Line numbers can vary :
Using config area from primary master device.
