Error description

  • APAR Error Description:
    Abstract: In Rational Developer for System Z (RDz) version
    7.6.2.2, attempts to add a new Dataset mapping on the Z/OS File
    System Mapping view might result in an out of memory or a freeze
    when refreshing the Remote System Explorer.
    Problem: Problem can be reproduced with the following scenario:
    
    1) set 'Default expansion page size' to 1500 under Preferences >
    Remote Systems > z/OS > MVS Files
    2) connect to a z/OS machine
    3) create a new MVS filter for CEE.SCEELKED: expanding the
    filter works and 1500 members are displayed with the 'more...'
    at the bottom
    4) create a new Data set mapping for **SCEELKE* / cbl and click
    OK:
    RDz freezes for about 30/40 seconds and then displays the member
    as COBOL files or throws an OutofMemory error.
    5) then add a new string to the filter CEE.SCEELKEX:
    no freeze or hang and 1500 members are displayed
    
    
    Local fix:
    After restart, RDz will display again the 1500 members with
    COBOL decoration without any problem.
    

Local fix

Problem summary

  • Changing extension by mapping triggers 1500 marker update jobs
    if 1500 member objects exist in the Remote Systems view. The
    already scheduled jobs try to run simultaneously and use up
    system resources. It could cause a client hang or OutOfMemory.
    

Problem conclusion

Temporary fix
