Error description

  • Error Message: N/A
    .
    Stack Trace: N/A
    .
    The "info mod" command in sdk/bin/jdmpview fails to list all
    expected libraries. This problem may occur when reading dumps
    that are in ELF format i.e. those produced by Linux platforms.
    Other symptoms that may be observed are
    1. no section info for the executable
    2. bad section address info for the executable
    3. bad symbol addresses for the executable and some other
    libraries
    4. Invalid section data for some libraries
    5. Two occurrences of "lib.so"
    

Local fix

Problem summary

  • The information about libraries is contained in two places
    within the ELF file: debug data in the executable and the core
    file's program header table. The dump reading code within
    jdmpview was failing to make use of all the information.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR1
    6.0.1 SR2
    .
    The dump reading code within jdmpview now uses both sources of
    information about libraries and as a consequence "info mod" will
    show all of them.
    The other five symptoms are also fixed.
    

Temporary fix
