ORA-600 [3137], ORA-600 [729] and ORA-600 [12224] During Operations Across Dblink (Doc ID 1939529.1)

Last updated on JANUARY 09, 2018

Applies to:

Oracle Net Services - Version 11.2.0.3 to 12.1.0.2 [Release 11.2 to 12.1]
Information in this document applies to any platform.

Symptoms

The following symptoms have been attributed to this issue:

a) Local database is 11.2.0.3 and a DBLINK to 11.2.0.4 remote database is present.

b) The following error or similar is seen in the local alert log:

ORA-00600: [3137], [1010], [], [], [], [], [], [], [], [], [], []
ORA-00600: [729], [160], [space leak], [], [], [], [], [], [], [], [], []

Note that it seems the ORA-600 [729] is a consequence of the ORA-600 [3137]

c) On remote node we see:

ORA-00600 [12224]


d) In the 'Incident Context' stack for the 600[12224] error we see functions:

OCIPing []
kpncllcurs []


The symptoms (a) and (b) might differ slightly with respect to database versions and the 2nd argument of the ORA-600 [3137] error.
However, for this article to be considered applicable (c) and (d) must be true.


Additional symptoms:

In the case of a dblink where a recent upgrade to either of these versions took place, the following errors might start appearing:

ORA-02050: transaction 12.113.80208 rolled back, some remote DBs may be in-doubt
ORA-03150: end-of-file on communication channel for database link
ORA-02063: preceding line from MY_LINK

Changes

These errors arose after applying latest PSU or upgrading to 11.2.0.4 at one of the databases involved in the dblink.
