Local fix

  • This issue can be worked around by copying the core file into
    HFS
    

Problem summary

  • The problem is caused when trying to jextract a core file larger
    than 2GB that is stored in a dataset.
    

Problem conclusion

  • This defect will be fixed in:
    5.0.0 SR12
    6.0.0 SR9
    .
    Jextract doesn't work with core file larger than 2GB on 31bit as
    the recordio libraries don't support it. However the work around
    is to use COPYDUMP or move the dataset to HFS and the new error
    message will explain this.
    .
    To obtain the fix:
    Install build 20100827 or later
    

Temporary fix
