ORA-3149 error in EM

Introduction:

I was receiving almost 100+ EM notifications every day which looks like below:

DDE: Problem Key ‘ORA 3137 [3149]’ was flood controlled (0x4) (incident: 461239)
ORA-03137: TTC protocol internal error : [3149] [] [] [] [] [] [] []
ORA-03149: Invalid Oracle error code
ttcdrvdmplocation: msg-0 ln-195 reporting 3137
Dumping ‘Buffer dump info:’ addr=0x10dd05110 size=412 bytes

EM said that the incident critical. However it wasn’t.

Environment:

Oracle EBS: 12.1.3
Oracle Database: 11.2.0.4
OS: Solaris Sparc 11

Cause:

This is a known bug in RDBMS Client 10.1.

Wait!

Where does this 10.1 come form? I am using 12.1.3 EBS with 11.2.0.4 Database?

Oracle AS 10.1.2 and 10.1.3 ( Used for Forms, Reports, Web ) also need a RDBMS client to connect to database. Both of them use RDBMS client 10.1 due to which this bug was coming.

Solution:

It’s a very simple fix. Apply the below patch to Oracle AS 10.1.2 (Forms and Reports Home) and 10.1.3 (Web) using OPatch to fix the issue.

Patch:

How do we apply patches to 10.1.2 and 10.1.3 ORACLE HOMEs? See the articles below for the same.
