Anyone familiar with using adb or mdb to attach to Unix (Solaris)
processes? I am working with Oracle Support, but the guy behind the
curtain (the developer) is in England, and it is hard to communicate
quickly since our shifts do not overlap for long.
This is what I have so far - I bomb on #5 with an "unknown symbol":
1. adb -P'> ' $ORACLE_HOME/bin/oracle
2. Wait for the "> " prompt
3. Determine the OS pid of the shadow ("oracle$ORACLE_SID") process. The
steps below assume that the pid is 123456.
4. Attach to the process by typing "0t123456:A" at the "> " prompt
5. Set a breakpoint in qmxtgrGetBindVal() by typing "qmxtgrGetBindVal:b"
at the "> " prompt.
6. Allow the process to continue execution by typing ":c" at the "> "
prompt.
7. Repeat steps 1-6 for all of the shared_server processes(p00x)and QC
process executing the "adb" command under different windows.
