APAR Error Description / Circumvention

-----------------------------------------------
PASE debuggers fail to start, producing endless error messages
when any file in the load map of the debug target cannot be
opened in the debugger job.

Messages like this appear when the problem occurs using the dbx
debugger:

> dbx -a 8
Waiting to attach to process 8 ...
libdebug assertion "(0)" failed at line 93 in file
../../../../../../../../../../../src/bos/usr/ccs/lib/libdbx/libd
ebug/modules/procdebug/ptrace/procdb_PtraceSession_Loader.C
libdebug assertion "(0)" failed at line 93 in file
../../../../../../../../../../../src/bos/usr/ccs/lib/libdbx/libd
ebug/modules/procdebug/ptrace/procdb_PtraceSession_Loader.C
... (error messages repeat until the debugger is killed) ...

Similar messages appear in spooled output file QPRINT for job
QTESPASSVR when the problem occurs using the IBM i PASE System
Debugger.

PASE system call ptracex returns an error if any file in the
load map cannot be opened for a PT_LDINFO or PT_LDXINFO request.
Library code handles the error by generating an error message
and retrying the syscall, which produces an endless sequence of
error messages for a persistent error such as "file not found"

CORRECTION FOR APAR MA47443 :
-----------------------------
LIC processing is changed to return without error for any
PT_LDINFO or PT_LDXINFO request that encounters a file error
(after setting set field ldinfo_fd to -1 for any file that
cannot be not opened)

CIRCUMVENTION FOR APAR MA47443 :
--------------------------------
None.


Activation Instructions
