ORA-02068; ORA-03113 ::DB Link Problems

Hi,
I have created a DB Link from to our client database MARS & i have named it as "MARS_DATA".
But my problem is whenever i query the data using 2 tables in it with a proper join condition using DB Link i am getting the following error.
ORA-02068: following severe error from MARS_DATA
ORA-03113: end-of-file on communication channel
NOTE:
Whenever i query the MARS database with a single table in it i am getting the data.(Using DB Link only)
Most surprising thing for me is when i am trying to execute the Errored out query after running the above it is working fine!!!
Can you help me in resolving this issue?
Regards,
Srinivas.

ORA-03113 errors should be resolved with the help of the Oracle Support.

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

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

I've had some problems in the past with in-doubt transactions with a DB link to a Sybase database. I can imagine it is more difficult for Oracle to manage transactions over a DB link if the the database is not Oracle. Especially with SQL Server/Sybase that do their own commit by default. Might that be the case here?
ORA-03113: end-of-file on communication channelThis also indicates a network problem.
You can also post this in the General Database forum.

ORA-02068+ORA-03113 on database link

Hi all
I have the following scenario:
The application is connecting to DB (Oracle 10.2.0.5) using jdbc connection pool.
The database is a 3-node RAC.
Using DB Link we access a PLSQL package on a remote database (10.2.0.4).The remote database is a single instance.
The remote database is not located behind FW.
Sometimes the remote DB is restarted, but we seem to hit these errors about 30 mins afterwards.
From time to time we get these errors and we cant find the root cause.
Any ideas how to address this?
Thanks,
Rudi

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.

The remote site (server process) crashed. There should be something in the alert.log, and trace file on the remote site.
It may also be the local site, so also look for local trace files.

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

Error ORA-02068,ORA-03135,ORA-06512 in Streams

Hi All,
I am new to Streams. Actually we are trying to replicate the data between 2 databases and we are using streams for this.
But we are getting the below error in DBA_PROPAGATION table.
ORA-02068: following severe error from TINFOT3
ORA-03135: connection lost contact
ORA-06512: at "SYS.DBMS_AQADM_SYS", line 1087
ORA-06512: at "SYS.DBMS_AQADM_SYS", line 7636
ORA-06512: at "SYS.DBMS_AQADM", line 631
ORA-06512: at line 1
It seems the capture process is running perfectly.
Can anyone suggest the solution or where to look more to troubleshoot the issue.
Thanks.
Amit.

The error looks like your target database may be down / dblink is not working / network issue..

ORA-02068, ORA-03135 - Connection Lost to Database - cancel session?

The situation:
We have an Oracle instance that we have no control over (3rd party maintained) and is shutdown on a nightly basis to do a cold back up. I'll call DB-A (8.1.7.4).
We have processes that run in Peoplesoft that selects from a view in database HR-B (10.2.0.3) that references tables in DB-A via a database link.
Peoplesoft does it's own "thread-pooling" and Oracle sessions that are created remain in an inactive state and get re-used as SQL statements are issued.
Problem:
As selects are made to the view with links to DB-A a valid session is created and remains inactive once the SQL is complete. During the night DB-A is shutdown and then started back up after the cold backups. In the morning a select is issued against the view to DB-A and tries to reuse the same session that was previously used. But since the DB-A was bounced the SQL statement gets an ORA-2068 and 0RA-03135 communication error. A second attempt seems to reestablish communication and is successful (using the same session). Adding to this problem is that multiple sessions could have been created and get reused by other processes and get the same error... so just adding retry process to a few applications does not seem feasible nor does it mean success.
Possible Solution and question:
Once DB-A is shutdown I would like to cancel any sessions in HR-B that may either be in a "bad" state, i.e. result in a communication error because it had last accessed DB-A. This way a new session would be created the next time a call is made to access data from DB-A... I've proven this to be successful via SQLPlus. Does anyone know if there is a V$ view that would show a session in a "bad" state like this? Or I would like to find sessions that executed SQL that referenced DB-A from HR-B and cancel those sessions. Does anyone have a suggestion? Thanks in advance.

I believe what you are looking for is: sqlnet.expire_time
You can put this in your sqlnet.ora file and set it for a time you want it to check for 'sniped' sessions, (or sessions that have been disconnected externally for some reason).
Reference a quote from D. Burleson's site:
The sqlnet.expire_time parameter is used to set a time interval, in minutes, to determine how often a probe should be sent verifying that client/server connections are active.

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 stringstring
Cause:     A severe error (disconnect, fatal Oracle error) received from the indicated database link. See following error text.
Action:     Contact the remote system administrator.
ORA-03113: end-of-file on communication channel
Cause:     The connection between Client and Server process was broken.
Action:     There was a communication error that requires further investigation. First, check for network problems and review the SQL*Net setup. Also, look in the alert.log file for any errors. Finally, test to see whether the server process is dead and whether a trace file was generated at failure time.

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> /

13:58:16 SQL> /
select count(*) from rp_adm.users

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.
