GDB should be available for Solaris as well if nothing else works.

Did you try to search for the required function name with nm or objdump?

Egor, you mentioned:

"There might be a catch here. Such program will not work without some
values (like address of fixed table). These values may change after db
startup and are obtained using ordinary SQL (via sqlplus, for
example). So if we want to use program that directly read data from
SGA of hanged database, we need to preliminary read some values
sometimes before database hangs (for example, immediately after
startup)."

That is helpful to know. I am still stuck on the debugger, and my sysadmins are not up to date with the latest debuggers we have, which are (Solaris 8):
dbx 6.2 (/opterp/ban7/SUNWspro/bin/dbx)
/bin/adb (unknown version)
/bin/mdb (unknown version)
