IT36287: IBM SPECTRUM CONTROL PORT PERFORMANCE CHARTS NOT DISPLAYED & PROBES FAIL WITH TURKISH LOCALE (BPCUI0002E).

IBM Spectrum Control 5.4.4 (August 2021)

APAR status

• Closed as Permanent restriction.

Error description

• The locale can bee in seen in the servers' logs. For example for
  the webServer, in
  TPC/wlp/usr/servers/webServer/logs/messages.log, a message like
  the one below can be noticed
  os = Windows Server 2016 (10.0; amd64) (tr_TR)Errors encountered
  in Spectrum Control while running in Turkish locale:
  -> Ports performance charts not being displayed, instead
  BPCUI0002E being displayed.
  -> all  IBM Storage Virtualizers probe failing and the probe's
  log contain errors like ( the probe fails while trying find
  console_ID from output file ) :

Problem conclusion

• On systems with locale set to Turkish, some
  Spectrum Control functionality becomes broken
  because under Turkish locale:
  
   - upper case of 'i' is the Turkish "dotted I"
  and "i".toUpperCase() is not equal to the English "I"
  
   - lower case of 'I' is the Turkish "dotless i"
  and "I".toLowerCase() is not equal to the English "i"
  
  Spectrum Control uses toUpperCase() / toLowerCase()
  and compares the results with constant English strings.
  
  These comparisons will give false-negative results
  because of the distinction described above, and
  results in a permanent restriction.
