3 -- This is the default implementation of the custom package
4 -- procedure that will be invoked to process a debug connection request
5 -- that arrives in the form of an ORA_DEBUG_JDWP environment variable.
6 -- This default implemenation is owned by SYS and is made available
7 -- to public via a public synonym.

9 -- The default implementation of this procedure does not perform any
10 -- additional security checks. A request to connect the session to a
11 -- debugger will be controlled only by the DEBUG CONNECT privilege
12 -- requirements. A database user who wants to perform custom security
13 -- checks as well can override this default implementation by defining
14 -- this same package in his or her own schema and implementing the
15 -- check in that local copy.
16
17 -- The arguments to the custom package procedure must all be of varchar2
18 -- type or of types which PL/SQL can implicitly convert to varchar2.

20 -- A programmer who wants to customize the handling of the debug connection
21 -- request may override this default implementation of the package procedure
22 -- by installing the same package (specification and body) with a procedure
23 -- of the same name in his own schema. He may customize the number and
24 -- names of the arguments to the package procedure. Only the names of
25 -- the package and of the procedure need to remain the same (namely
26 -- (DBMS_DEBUG_JDWP_CUSTOM and CONNECT_DEBUGGER respectively). The
27 -- programmer's customized version of the package may contain overloaded
28 -- versions of the procedure CONNECT_DEBUGGER with different arguments.
