ORA-02068 errors

Our application is being plagued by an ORA-02068 error.
We have two database servers that communicate via dblink (over a frame). One is on Solaris running 8i, the other NT running 7.3.4. THere is a pl/sql procedure on the solaris instance that calls a pl/sql procedure on the NT instance. Occasionally we get the following error:
ORA-02068: following severe error from CNQA.WORLD
where CNQA is our database link.
ORacle documents the err02068, 00000, "following severe error from %s%s"
// *Cause: A severe error (disconnect, fatal Oracle error) received from
// the indicated database link. See following error text.
// *Action: Contact the remote system administrator.
or as follows:
We do have a firewall that has been configured to allow sqlnet connectivity between Unix and NT.
The problem is intermittent. We have raised the number of open links, as well as sessions.
Any suggestions? Has anyone else experienced this problem?
Thanks in advance for any help!

ORA-02068 Error Message

I recieved this error message, when running a procedure:
ORA-02068: following server error from DBLINK
ORA-03114: not connected to ORACLE
ORA-06512: at line 13
DBLINK is a database link to a remote database. Is it as simple as the remote database being offline..or is a different problem possible?
Thanks,
Duncan

Is this an Oracle to Oracle connection? Or is the addressed database a non-Oracle database? The combination ora-02068 and ora-03114 is typical for Heterogeneous Connectivity and/or Gateway Connectivity.
The basic problem is ora-03114 (You are not connected), it does not necessarily mean, database is down.

ORA-02068 errors using a DB Link between source and remote db servers

I get the following error when I query a table or view on a remote database using a db link:
13:58:13 SQL> /
COUNT(*)
92862
13:58:16 SQL> /
select count(*) from rp_adm.users
ERROR at line 1:
ORA-02068: following severe error from DURS.CONDEVD1.WORLD
ORA-03113: end-of-file on communication channel
14:03:53 SQL>
As you can see, the query works sometimes and then if I wait about 5 minutes, I get the error. If I run the query immediately after the error, it works fine.
rp_adm.users is a view which within the DDL it queries a remote database using a db link.
Any one have any idea how to get rid of this ORA-02068 and ORA-03113 error????

By the way, this is running on Solaris 10 OS running Oracle Database 10g Enterprise Edition Release 10.1.0.5.0 - 64bit databases.

ORA-02068 + ORA-03135

Hi,
we are getting this two ORA-02068 + ORA-03135 errors on application side using dblink .... can any one pls help....
for 03135 we did some changes on db side .. what about ORA-02068 , is there is any action we have to made for this 2068 error
Thanks,

Hi,
I have a similar problem... but more strange...
The customer have an aplication on JBOSS with a Oracle database 10.2.0.4.
When the user is logged in the application, he makes a query through the application, this query run a procedure that makes a select on the DB local an conects a remote DB with a db_link connection, with a synonym on the table remote and the procedure that fails
This procedure have a EXCEPTION clause at the end, that insert in a "error table" that shows the following information:
PET_ID ERROR DESCRIPTION F_CREATION USER_CREATION
4565 -2068 ORA-02068: error grave de DB_COSTES 25/05/2011 09:41;11 [jboss]-xxxxxxxxx
ORA-03135: la conexión ha perdido contacto
4566 -1001 ORA-01001: cursor no válido 25/05/2011 09:41;47 [jboss]-xxxxxxxxx
4567 -1001 ORA-01001: cursor no válido 25/05/2011 09:41;48 [jboss]-xxxxxxxxx
4568 -1001 ORA-01001: cursor no válido 25/05/2011 09:41;49 [jboss]-xxxxxxxxx
The error "ORA-01001: cursor no válido" appears on the "error table" when the user tries to re-run another searh in the application
The DBA (in client side) must drop/create the synonym on the table and recompile the procedure to be able to work again... so, this error INVALID the procedure.
It's not for iddle time of application, because I asked for the user and he said me that when he logged at the first time in the morning, and make the search, he got the error too.
Can anybody help me?
Thank you

Oracle errors: ORA-02068 + ORA-03113

Hy everybody,
we're experiencing a problem with a connection of a weblogic's pool:
(here's workshop's log excerpt):
<Id=sysContattiJcx; method=controls.data.SysContattiInbound.insertManuale(); Failure=java.sql.SQLException:
: distributed update operation failed; rollback required
ORA-02068: following severe error from CONTATTI_CRMB
ORA-03113: end-of-file on communication channel
[ServiceException]>
the problem is encountered while updating a record on a synonim table which points
to a remote oracle instance via a dblink.
All other sql statements executed on local db instance's tables (i.e. the instance
the pool is configured upon) go ok.
I've read on a previous post that the problem is related with the restart of
the remote db instance AFTER the creation of appserver connpool, which in turn
determines the corruption of connections towards the remote instance (i.e. their
state is STALE towards the remote instance even if - at the same time - HEALTY
toward the local db instance...)
Our problem is that we restarted the application server in order to be sure to
re-establish all the connections, but the problem still stands there.
Any other suggestions?
thanks

[ServiceException]>This is an oracle communications problem between the driver and the DBMS, or between the
immediate DBMS nd the remote DBMS. The end-of-file failure means that one end of a
communication was dropped. I suggest you get some Oracle support to help find the
problem. If you shut weblogic down and brought it back up, and the problem is still there,
even on the first invocation after coming back up, then it is a problem between the DBMSes.

ORA-02068: following severe error from db link

Hi,
I have the following piece of code which gives an error.
FOR items IN (SELECT DISTINCT item FROM ccm_items@caav_link a)
LOOP
itemtrans.process_item@manuf_link(items.item);
END LOOP;
Procedure process_item may take several hours to complete execution. Hence after processing one or two items, I get an error "ORA-02068: following severe error from caav_link
ORA-03113: end-of-file on communication channel"
I guess this occurs due to some timeout issue. Can you please give some pointers on why this issue occurs and how to avoid it? Also note that I need to use the same link after the loop. So a timeout could cause a problem there also.
Thanks,
Blesson

ORA-02068: following severe error from - How to handle the overgiven Except

Hello again ^^,
hope its okay to write the follwnig question into a new Thread...
I sometimes get errors from remote dbs.
ORA-02068: following severe error from DBLINK
ORA-01089: immediate shutdown in progress - no operations are permitted
ORA-02068: following severe error from DBLINK
ORA-03113: end-of-file on communication channelThese are in one sqlerm. Is it possible to handle the second errors without string operations?
Thanks and regards
Edited by: user10283133 on 28.10.2008 08:33
Try to force the headline

The remote db is accessible from 6 am to 6 pm. When querring longer than given time span I get the Error ORA-02068. In the sqlerm for this Error is a second Errormessage from an second different Error concatenated.
Now I will tell what I think is happening:
I think the remote db say: >>I will go sleep now<< an throws Error A (ORA-01089 (or ORA-03113, or what else)). This Error A goes to the local db. The local db get the Error A and throw a new Error (Error B = ORA-02068). This Error B is independet from Error A. And I see a String which is "Error B + Error A"
I recieve also three possible Errormessages:
ORA-02068: following severe error from DBLINK
ORA-03113: end-of-file on communication channel
ORA-02068: following severe error from DBLINK_ODS_STBY
ORA-01089: immediate shutdown in progress - no operations are permitted
ORA-02068: following severe error from DBLINK_ODS_STBY
ORA-whatelse: what elseI can handle the ORA-02068. But my questions is, can I handle the second Error (thus Error A) without string operations?
The Relase is 10g2. Please tell me which information you still need ...
Thank you very much.

ORA-02068: following severe error from dblink

Dear friends,
My database (oracle 9.2.0.8.0) will call another database's (oracle 9i cluster) view through DB Link to get some data.
If we are to access the data for the first time in a particular session, it gives the output within a second.
But if we access the data after 45mins in the same session(already connection is open), the query is running for 9 mins it throws an oracle error.
There is no network issue also(solaris 5.8 server).

Strange errors ORA-02068 ORA-00600

Hi,
I have a strange error in my mapping, that I have never heard before.
In the source schema, I have a table that I check, that gives me a list of PK in order to know which lines I have to take in the other table of the schema.
At the end of the mapping, I have to UPDATE the table in order not to take the lines when the mapping is executed the next day : there is a field which is a flag that I have to update from 0 to 1.
But the mapping never manage to UPDATE all the table, it gives me these errors :
ORA-00600 : internal error code, arguments : : [kdoorp-1], [15], [0], [], [], [], [], []
ORA-02068 : following severe error from [DB_LINK_NAME]
I made a mapping which only update the table and it doesn't work anymore. What is strange is that it stops the first time after 1003 rows updated, the second time 2007, the third 4014, etc... ? I don't understand ???!!
Can someone help me ?
Thanks,
Nico
