identically. The exact behavior shown by HP 9000 GDB under ARIES may differ
from that on a HP 9000 HP-UX server.
• If the debugged process is blocking in a system call, any attempt to get to the GDB
command prompt by pressing ctrl-C does not work. The process needs to be killed
from a different shell.
• ARIES does not provide true emulation of MxN threads, and thus does not support
debugging of HP 9000 applications that are linked with pthreads library and create
threads in MxN model.
NOTE: The HP 9000 applications linked with MxN pthreads library are emulated
under ARIES as traditional 1x1 threads, and thus can only be debugged under
ARIES as any other non-MxN multi-threaded application.
• ARIES supports debugging of 32-bit and 64-bit HP 9000 HP-UX applications using
32-bit HP 9000 HP-UX GDB. 64-bit HP 9000 HP-UX gdb is not supported under
ARIES.
14.30.2 Attaching GDB to an already running emulated process
You can attach GDB to an already running HP 9000 application process on HP-UX 11i
for HP Integrity servers to debug the application. After a successful attach, all of the
GDB commands work in exactly the same manner as they do on an HP 9000 HP-UX
server.
Use the steps below to attach GDB to HP 9000 application process under ARIES on
HP-UX 11i Integrity servers:
• Perform the same preparatory steps as required for debugging an HP 9000 HP-UX
application using GDB under ARIES on HP-UX 11i Integrity server.
• Invoke GDB as follows:
gdb <pa_process_name> <pa_process_name>
You can also invoke GDB through any of the attach modes supported by GDB
using the -pid <pa_pid> option or by issuing the attach <pa_pid> command
at the gdb prompt
After the debugging, the process can continue or abort, as specified by the user. This
feature is especially useful when triaging problems in an environment with a large
number of processes and a mix of Integrity native and HP 9000 processes.
14.30.3 Detecting memory leaks using GDB under ARIES
Applications cannot leak memory under ARIES unless they do so on HP 9000 servers.
HP GDB can be used to detect memory leaks of HP 9000 applications under ARIES.
Refer to HP GDB documentation for more details.
