oradebug translate_addr

oradebug translate_addr 0x… translates a memory-address to a symbolic name (such as internal function names).

On Windows, this can be demonstrated with the Symbolic Debugger (cdb.exe):

First, cdb.exe is started and attached to oracle.exe:

C:\> cdb -pn oracle.exe

Then, the (exported) symbols of oracle.exe are displayed with the x command:

0:004> x oracle!*
*** WARNING: Unable to verify checksum for c:\oracle\19\bin\ORACLE.EXE

00007ff7`61758030 ORACLE!qxiqitbe (<no parameter info>)
…

I choose any of the displayed functions, for example qxiqitbr. The respective address is 00007ff7'61756e80. So, I look up this address with oradebug:

sys> oradebug translate_addr 0x00007ff761756e80
0x00007ff761756e8 qxiqitbr()
