Erro ORA-03106 communication protocol error

Hi,
I got this error when i tried to connect to oracle8i version 8.1.6 from windows 98 station using oracle7 client in the station.
Oracle7 that i'm using it's personal oracle but i used NET assiest and created service name (test) to connect me to network version as follow test/test@test but i got the error above.
Thanks in advance

This error is too generic. NLS-related issue is ONE of many other possible reasons. So call Oracle support.

ORA-03106: fatal two-task communication protocol error USING INFORMATICA

Hi,
We are testing Oracle 10203 with linux using INFORMATICA 8.1.1
The user who run the informaica is getting the following error , after runing query against a remote database.
READER_12_1_1> RR_4035 SQL Error [
ORA-03106: fatal two-task communication protocol error
(Please note that informatica is not using db links to open a connection against a remote db).
The informatica client is installed on the same machine as the oracle database and they are using the same oracle client (e.g: 10203)
I also set a trace in the sqlnet.ora at server side and at the client side.
No error regarding ora-3106 was generated in the trace files.
I also added: alter system set events '3106 trace name errorstack level 10', but nothing writthen to the trace file.
Any suggestion ?
Thanks.

Error: ORA 3106
Text: fatal two-task communication protocol error
Cause: The communication path between Oracle and the user task has stopped.
This is an internal error message not usually issued.
Action: Contact customer support.
====================================================
Unfortunately the error text doesn't lie, this error is difficult to catch. You may search metalink's knowledge base for possible reasons,but there are many. And, since this is a 3rd party application, I would ask INFORMATICA (not Oracle), do they certify against 10g? Sometimes simply the application is not ready for the used Oracle version.

Got this error when opening the peopletools application designer 8.49. The same is working fine within the server, but not working from the client's machine.
We can still able to connect to the database & URL
Please help by throwing some lights.
Thanks,

Looks like a SQL error. ARe you able to connect to the database with SQL*Plus ? Probably the Oracle client is badly configured.

What is the oracle database server and the jdbc driver you are using?
Most
of the time this happens because the jdbc driver is not compatible with
the
oracle server.

Help about "ORA-03106: fatal two-task communication protocol error"

Hello.
After having changed some functions written in pro*C, I am getting "ORA-03106: fatal two-task communication protocol error", in the functions I have changed (all of them).
Can someone tell me what the problem can be ?
Tahnks in advance.

The problem seems to be in pro*C code:
My pro*C function is like this:
int CSRIRDB_checkGT(char* in_CO_GT_V,
char* out_SQ_GZL_01)
int var_Error = CSRIRDB_OK;
char var_Sqlerrmc[2000];
char var_msg[512]; /* 512 es la longitud máxima del mensaje oracle incluyendo saltos de línea */
size_t var_buf_len, var_msg_len;
/* and the error is beacuse the following assignment */
:out_SQ_GZL_01 := to_char(v_SQ_GZL_01);
/* where v_SQ_GZL_01 is a NUMBER(5) */
I don't know what I'm doing wrong.

ORA-03106
========
Possible reasons for the ORA-03106 errors include:
1. Incompatibilities between the client application and the RDBMS server.
For
example, version incompatibilities, or a client trying to use a feature not
supported by the database kernel.
2. When using database links or gateways.
3. Network or SQL*Net problems.
4. Corruptions.
5. PL/SQL - language related.
RDBMS - Troubleshooting two-task common errors
==============================================
1. Check for NLS incompatibilities between the client and server. This is
a very popular cause of the ORA-03106 error.
2. Check the alert log and RDBMS trace files for any pertinent information /
errors that coincide with receiving the ORA-03106 error.
3. Try to get a testcase and reproduce the problem in-house.
4. If a testcase is not possible, ask for SQL*Net trace files, SQL traces,
and
try setting event 3106 to obtain the error stack.
5. In extreme circumstances, this could indicate that a shared memory
segment
used by Oracle is corrupted. You will have to shut down the database,
possibly using the abort option. Make sure all semaphores have been
released by using the IPCS command on Unix. Oracle uses semaphores to
control concurrency between all of the background processes (pmon, smon,
drwr, lgwr, and oracle shadow processes). Semaphores are also used to
control Two-Task communication between the user process and the shadow
process.
6. Try and narrow down the code that may be causing it. For example it might
have started to happen after increasing the number of parameters in a PL/SQL
block or when using certain values for bind variables, etc.
7. If we still do not make headway, file a bug under RDBMS, but we still may
need some or all of the above information as indicated above
hope it helps!!

the db link connects to specific user
when i access the table with same name as user then recieve following message
ORA-03106: fatal two-task communication protocol error
when i access the other tables having different name that the user to which the db link connects
that works alright
so what is solution of problem in this particular case?

What is your Oracle release? Is it 9.0.1.2 or 9.2.0?
What version of Sql*Plus client are you using?

PHP - TWO_TASK Communication protocol error

Hi all,
I've 8I on RedHat 6, with Apache 1.3.9 and PHP3.
When we try to do some select statements from the database, we
get:
OCIFetch: ORA-03106: fatal two-task communication protocol
error
The variable TWO_TASK is defined to our tnsnames.ora entry.
If the select statement returns only one row, there is no error.
I've no idea what's happening.
Can anyone help?
Thanks in advanced,

Although this question is completely off topic of the Personalization you can learn how to configure the SQL*Net connect from the manual by reading the topic "Configure the Client to Use a Net Service Name" found at the following link:

You're attempting to go across SQL*Net. I'm a unix guy so I can't help very much except to point this out.
On Unix I'd either undefine the TWO_TASK environmental variable. Probably a reg entry on 2k.
Or configure Sql*Net.

Ora-03137 ttcp protocol error

Hi
ora-03137 ttcp protocol error.....i am using oracle database 11g release2 and operating system is windows xp service pack 2, 64 bit processor....plz tell me the causes for the error and solution
for it.
Edited by: 793097 on Sep 6, 2010 10:14 PM

Hi, this error can be related to the network problem. This tells that the connection between the client and server dropped for some reason.
May be there is some network dis connectivity or firewall or even bug in the software or in database itself.

ORA-03106: Fatal Two Task Communication Protocol Error due to multilanguage

1) I have installed oracle 10.2 with multi language support enabled Unicode (AL32UTF8) on windows 2003 Server.
2) Forms 6i installed on same machine but Form close immediately after Database connection.
3) In Net8 Easy Config following error appear "ORA-03106: Fatal Two Task Communication Protocol"
4) If I reinstall database without multi language support, Forms run and connect successfully.

Forms 6i does not support multi language support enabled Unicode(UTF-8)
and unicode character has to take a long word size where form6i word's length is less
thats why the message is coming as Two Task Communication Protocol because the same protocol
is used for both database as well as for form6i and database is capable of taking unicode characters
whereas the forms 6i is not able to perform the same.
