Question: What
causes the ORA-031237 error?
Errors in
file /opt/oracle/diag/rdbms/trace/OMNIDB2_ora_2729.trc:
ORA-03137: TTC protocol internal
error : [12333] [4] [195] [2]
Answer: The oerr utility shows
this for the ORA-03137 error:
ORA-03137 TTC
protocol internal error: [%s] [%s] [%s] [%s] [%s] [%s] [%s]
[%s]"
Cause: TTC protocol
internal error.
Action: Contact
Oracle Support
As we see, there is an associated trace file and this
file will have more information on the ORA-03137 error.
This is usually a bug.
This is an internal error and you need to open a SR on
MOSC.
In 11g, there is fix by upgrading to Oracle 11.1.0.7. and a workaround by setting
"_optim_peek_user_binds"=false. Set this parameter ON
LY with the consent of MOSC.
Solarwinds notes this on the ORA-03137
"Although upgrading to database
version 11.1.0.7 has been confirmed to have solved this
issue in a high number of cases, error ORA-03137 [12333]
accompanied by Protocol Violation messages may still occur
intermittently in database versions prior to 11.2, including
database 10.2.0.4 and 11.1.0.7.
This has been reported in unpublished
bug:8625762 ORA-3137 [12333] due to bind data not read from
wire, in which case ORA-3137 [12333] can occur
intermittently for SQL which uses user binds due to bind
data being left unread on the Net connection.
The bug suggests the workaround of
setting "_optim_peek_user_binds"=false to avoid this problem
(workaround to be used with caution as it can affect
execution plans chosen by CBO), and also provides the fix by
the application of
Patch:8625762"
