IT47870: PCOMM V15.0.1 (32BIT) - HANGS AND CRASHES WHEN USING WITH ENTERPRISE SINGLE SIGN-ON (SSO)

APAR status

• Closed as program error.

Error description

• Users are experiencing hangs and crashes with their PCOMM.
  
  This started when they integrated it with their Enterprise
  Single Sign-On (SSO) software (Evidian v10.2).
  
  They encounter this recurring problem, where their PCOMM freezes
  (or hangs) and then crashes, when they accessed it through their
  SSO system.
  
  This issue is consistently reproducible across multiple versions
  of their PCOMM (v12 and v15).
  
  Furthermore, users confirmed that there are no hanging issues
  with PCOMM when the SSO integration is turned off.
  

Local fix

Problem summary

• The EHLLAPI application invokes the CopyPresentationSpace(5)
  API, which fails while processing the Sukoon or Euro sign
  contained on the presentation space. This failure blocks
  subsequent API executions, consistently returning Resource
  Unavailable (return code 11). Consequently, the blocked APIs are
  leading to hangs or crashes.
  

Problem conclusion

• A new keyword, IgnoreEuroSignForArabic=Y, has been added under
  the [API] section in PCSWIN.INI to bypass Euro sign processing.
  If an API block occurs with Return Code 11, the reset function
  is triggered to prevent disruptions.
  
  Below keyword needs to be added in PCSWIN.INI
  [API]
  IgnoreEuroSignForArabic=Y
