generate a core file from a running process

[Patrick McGleenon]

Anyone know if there's a program out there to generate a core file
from a running process - without stopping it - on AIX (5.1)?

I'm looking for something like gcore on Solaris, gdb 5.3 supports
generate-core-file/gcore only on Solaris + linux.
dbx doesn't appear to support it at all

Thanks

Patrick

Last I checked, AIX doesn't support this. I believe Solaris and
Linux both use the proc filesystem to generate core files in this
manner. AIX now has a proc filesystem, so if you have IBM support
you can call them and submit a change request.

How about something like this:

pid_t ChildPid;
int Status;
void (*PrevSIGABT)(int);

PrevSIGIOT = signal(SIGABT, SIG_DFL);

ChildPid = fork();
if (ChildPid == NULL)
abort();
else
waitpid(ChildPid, &Status, NULL);

signal(SIGABT, PrevSIGABT);

True enough, but that only applies in the case where you have
the source code to the application.

You can use "gencore" on AIX 5.2

Not sure is backported to 5.1, raise a PMR with IBM support to backport it.
