IV19634: JDMPVIEW INFO MOD COMMAND IS MISSING LIBRARIES

APAR status

• Closed as program error.

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
