APAR status

  • Closed as program error.

Error description

  • When a BP executes a CD Begin Session Service,
    the CDSA considers its current session load and either
    executes or suspends the request.
    Suspended requests are resumed as resources
    become available, but are taking an unusually long time
    to resume.
    

Local fix

  • STRRTC - 464802
    GUB / GUB
    Circumvention: None
    

Problem summary

  • Users Affected:
    All
    
    Problem Description:
    PNODE sessions suspended because of insufficient PNODE session
    resources eventually resume, but at a very slow rate.
    
    Platforms affected:
    All
    

Problem conclusion

  • Resolution Summary:
    Suspend Queue processing performance has been improved by
    allowing returning sessions to claim suspendended session of
    other group member adapters, instead of restricting selection to
    those belonging to itself. In addition, a number of scenarios
    have been improved including automatic
    resumption of suspended sessions when an adapter goes down with
    sessions in the suspend queue.
    
    IMPORTANT: This release modifies the database schema and
    requires all nodes in the cluster to be down before proceding
    to install the interim fix.
