# GET dblink DDL

SQL> select dbms_metadata.get_ddl('DB_LINK','SRP1','PUBLIC') from dual;

DBMS_METADATA.GET_DDL('DB_LINK','SRP1','PUBLIC')
---------------------------------------------------------------------------------------------------

  CREATE SHARED PUBLIC DATABASE LINK "SRP1"
   CONNECT TO "SRP" IDENTIFIED BY VALUES 'xxxxxxxxxxxxxxxxxxxxxx'
   AUTHENTICATED BY "SRP" IDENTIFIED BY VALUES 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
   USING 'ng1_weejar_a1';

根据MOS NOTE 1380017.1 记录属于在当前版本下使用shared public dblink时触发， 应属于bug 12977043

Typically this will happen when using shared, public database links,
however any other configuration that could result in an ORA-23 being
raised at the remote site could be a case of this bug.

To confirm that this is the case, search for the string “struct ncodef ** uganc_p”
in the trace file and identify the NCOFLG value. If the bits 0x0200 (NCODBCONC)
and 0x1000 (NCOSESSTICKY) are set, then this is the right bug.

Example:

From the trace file we search for “struct ncodef ** uganc_p” and find
the following:

struct ncodef ** uganc_p [021FDD638, 021FDD640) = 224D7888 00000000
NCONAM = ‘IMSVCSLNK.WORLD’
NCOUID = 45
NCOFLG = 12930
NCO2PSTR = 1
HSTPRO = 6
HSTFLG = 1073753505

The value of NCOFLG is 12930 = 0x3282 and since we have both the
0x0200 and the 0x1000 bits set, this confirms the duplicate.

Solution
Use a Public database link instead of a Shared database link
OR
This issue is fixed in:
12.2 (Future Release)
11.2.0.4 (Future Patch Set)
11.2.0.3 Patch 17 on Windows Platforms
