Error description

  • Expanding a zComponent project in Rational Developer for System
    z (RDz) from the z/OS project explorer is much slower (>10s)
    than from the Resource perspective (3s)
    
    Steps to reproduce:
    
    1- expand a zFolder (for example MyProject\zOSsrc\SRC.COBOL):
    RDz is blocked for more than 10s and then
    the list of files is displayed
    3- click on the collapse all icon of the z/OS Project Explorer
    tab and repeat step 1: same performance again
    4- restart RDz
    5- open Java perspective or Resource perspective and expand the
    same folder: it takes less than 5s
    
    Problem has been observed with zFolder but can also be
    reproduced with a local RDz COBOL project.
    

Local fix

  • Expand folder from Resource or Java perspective
    

Problem summary

  • Expanding a zComponent project in Rational Developer for System
    z (RDz) from the z/OS project explorer is much slower (>10s)
    than from the Resource perspective (3s)
    

Problem conclusion

  • RDz was performing a relatively expensive operation on every
    file when deciding how to display the file in the UI when
    expanding the parent container.
    
    We moved the operation so that it will only be performed when
    necessary.
    
    The problem listed in this APAR has been resolved with
    IBM Rational Developer for System z V9.0.1.4 Fix Pack which
    is available from the Recommended Fixes support download page:
