APAR status

  • Closed as program error.

Error description

  • If EXTSHM=ON or EXTSHM=MSEG is set, then the
restore/restbyname command may fail with error message
such as:

restore: 0511-110 There is an unpacking error.
restore: 0511-708 There is an internal unpacking error:
  decode failure
restore: 0511-121 Out of space.

Or:

restore: 0511-147 Unpacking file size error.
The original size of ./usr/lpp/bos/bos.rte.shell/
  6.1.8.15/liblpp.a is 352990; restored size is 6153.
restore: 0511-708 There is an internal unpacking error:
  decode failure
restore: 0511-107 Cannot read from pipe. There is an
  unpacking error.
: A specified file does not support the ioctl system
  call.


Two situations where this issue has been seen are when
using 'mkwpar' to create a 5.2 Versioned WPAR on a 7.1
 system, and when doing an alt_disk_copy of a 6.1 system.

Local fix

  • unset EXTSHM before any command that may call restore,
such as mkwpar and alt_disk_copy

Problem summary

  • When EXTSHM=ON or EXTSHM=MSEG is set, then the
restore/restbyname command may fail with error message
such as:
restore: 0511-110 There is an unpacking error.
restore: 0511-708 There is an internal unpacking error:

Problem conclusion

  • The restore/restbyname has been fixed to avoid the overflow
of the variable which was leading to this problem.

Temporary fix
