IZ70707: JVM DOES NOT RESPECT SYSCTL KERNEL.CORE_PATTERN

APAR status

• Closed as program error.

Error description

• Error Message: JVMDUMP012E Error in System dump: cannot find
  core file: "No such file or directory". check "ulimit -Hc" is
  set high enough
    JVMDUMP032I JVM requested Snap dump using
  '/test/Snap.20091207.140721.6092.0002.trc' in response to an
  event
  .
  Stack Trace:
  .
  

Local fix

Problem summary

• The "sysctl -w kernel.core_pattern" command allows a user to
  modify where all core files on a system are generated.  However
  the JVM did not respect this setting, and gave a misleading
  error message referring to "ulimit -Hc".
  

Problem conclusion

• This defect will be fixed in:
  5.0.0 SR12
  .
  The JVM has been updated to respect the kernel.core_pattern
  sysctl.
  Note that the %t modifier is not supported.
  .
  Core files will be written to the directory specified by the
  kernel.core_pattern sysctl and can be used for problem
  investigation.
  .
  To obtain the fix:
  Install build 20100218 or later
