PL/SQL :ORA-04052 with Database link

i have created a database link in my producation database as following
CREATE PUBLIC DATABASE LINK <NAME>
CONNECT TO <USER>
IDENTIFIED BY <P/W>
USING <CONNECT STRING OF TARGET DATABASE
oracle version 9.0.2.8
OS : Windows 2003 EE R2 SP2
Using oracle failsafe 3.3.4 with windows cluster
Problem Description :
whenever i run my pl/sql procecdure to pull the data from the target database i get the following error
ERROR at line 3
ORA-06550:line 3 column 2
PL/SQL : ORA-04052: error occured when looking up remote object _<SCHEMA>.<TABLE>@<DATABASE LINKE NAME>_
ORA-00604 : ERROR occured at recursive SQL level 1
ORA-03106 : fatal tow-task communication protocol error
ORA-02063: preceding line from <DATABASE LINK NAME>
I have tested the same way in the test environment the same oracle version as well the OS but without oracle failsafe and windows cluster
the script goes smoothly with out any errors.
i have google and checked the OTN for all available solutions but still nothing its not getting throw
i will be very thankful for your replys and solutions
any farther clarification i am ready
thanks in advance

Hi,
This forum is for issues connecting to non-Oracle databases. As the problem is using PL/SQL to connect to another Oracle database then it would be better to post a thread in the PL/SQL forum -
PL/SQL
If you are trying to connect to a non-Oracle database then please give us the details of which non-Oracle database and the software you are trying to use to connect.

ORA-00022 with Database Link and Trigger

Hello altogether,
I got a very strange behaviour with my oracle 10.2.
I have two nets N1 and N2, where N1 can access the servers in N2, but not the other way round. In both nets I have an Oracle database running (D1 and D2).
In N1 I calculate some data, which must be replicated to the database in N2. I do this by using triggers on my tables in database D1 copying the inserted or changed data to D2 by using a shared public database link.
This works fine most of the time. But sometimes I get the following error:
ERROR [STDERR] Caused by: java.sql.SQLException: ORA-02068: following severe error from D2
ORA-00022: invalid session ID; access denied
ORA-06512: at "CUSTOMER", line 13
ORA-04088: error during execution of trigger 'CUSTOMER'
When I use the database links manually, they work.
Any idea?
Thank you!!
Daniel

The ORA-02068 message might be important
02068, 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.Have you searched Oracle support for any bugs associated with the ORA-02068?
Was the remote session killed, the remote database changed to restricted session, or bounced?
I take it the distributed session is created using a dedicated session and not shared server?

PL/SQL: ORA-04052: error occurred when looking up remote object.

Hi All,
I'm getting the following error message while executing a PL/SQL Block.
PL/SQL: ORA-04052: error occurred when looking up remote object UPLDUSER.filestatushistory@FTS
ORA-00604: error occurred at recursive SQL level 1
ORA-03106: fatal two-task communication protocol error
ORA-02063: preceding line from FTSStatement
declare
v_coun number;
begin
select count(*) into v_coun
from updluser.filestatushistory@fts;
end;Back ground of the situation as follows,
My DataBase version 10.2.0.3 DB Name :DB1
Table Owner : UPLDUSER
Table Name : FILESTATUSHISTORY
I have a report user on the same database and I have grant all on the above table to report user
Report User : RPT_FTS
SQL> GRANT ALL ON FILESTATUSHISTORY_V TO RPT_FTS;Now Please find the below database details where I'm getting subjected error.
Database version : 9.2.0.8
DB Name : DB2
User Name : RPT_REPORTS
I Have create a dblink from RPT_REPORTS to RPT_FTS on DB1 and the dblink works fine. But getting the above error while running it.
but When I do the same other 10.2.0.3 db , the above PL/SQL block works fine without any problem.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Now the strange about this is that I have Created a new table on DB1 db like below;
SQL> CREATE TABLE UPLDUSER.ABC AS SELECT * FROM FILESTATUSHISTORY;and retry my code on DB2 (9.2.0.8) after changing the table to ABC and it worked. Now I don't know whats wrong with a original table(FILESTATUSHISTORY).
To over come the problem and a work-a-round method I create a view on the DB1 (RPT_FTS) like the below
SQL> CREATE VIEW FILESTATUSHISTORY AS SELECT * FROM UPLDUSER.FILESTATUSHISTORY;and was able to run the PL/SQL block Remotely.
Just wants To know what whould have been the cause for this .
Cheers

Hi Kanchana,
Perhaps following link of google search has answer to your query
ORA-04052. The search result contains some useful articles whose URLs I shan't post in the forums.

Strange problem with Database LInk

Hi Everyone,
I have strange problem with Database Link in Oracle 11g Express Edition;
There are two computers: computer-server and computer-client. Tnsnames.ora are the same on both computers ie.
CT =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = krzysztof)(PORT = 1521))
(CONNECT_DATA = (SERVICE_NAME = XE)
I created database link :
Create database link zdalny
Connect to <user_id> identified by <password>
using ‘CT’;
Client can’t connect with server when I am using above command. But when I change “using” for using ‘krzysztof:1521’ or using ‘krzysztof’ or using ‘server IP:1521’ – everything is ok.
Why I am asking. Because in all materials which I am reading about Oracle command with using ‘CT’ should be working correct. But there is not. Do you know, why?
Thanks in advance and apologize for my English.

PS. I tried with using 'XE' - not working.Assuming that is the correct tnsnames, of course XE is not working. You don't have a tnsnames entry for 'XE'.
You need to be aware that when using a dblink, the client is the db in which the link is defined, not the desktop from which you connect to that database.
I think you need to start here:
http://edstevensdba.wordpress.com/2011/02/26/ora-12154tns-03505/
http://edstevensdba.wordpress.com/2011/02/09/sqlnet_overview/ (Help! I can’t connect to my database )
http://edstevensdba.wordpress.com/2011/02/16/sqlnet_client_cfg/ (Help! I can’t connect to my database (part duex) )
The fact that your client (db link) is a database doesn't change anything taught in the above.

How to catch PL/SQL: ORA-04052 error?

I need to execute a procedure that select remote objects but the remote db is a RAC DB and I only have access to one of the nodes, the remote RAC have load balancing enabled and the remote DBA can’t create a DB Service for my connection, so, I have to re-run the execution of my procedure until it connects successful to the remote DB through a db link, but I can’t catch the error ORA-12541: TNS:no listener.
Someone knows how to catch the error??

I could confirm that you would never branch to the exception in case of no listener!
So another possibility that comes to mind is to enclose the remote select in an execute immediate and only execute it if you could establish a connection via UTL_TCP:
Something along those lines:
michaels> DECLARE
   conn               UTL_TCP.connection;
   l_date             DATE;
   no_listner_excep   EXCEPTION;
   PRAGMA EXCEPTION_INIT (no_listner_excep, -29260);
BEGIN
   conn := UTL_TCP.open_connection ('fleet', 1569);
   EXECUTE IMMEDIATE 'select sysdate from dual@fleet_new'
                INTO l_date;
   UTL_TCP.close_connection (conn);
   DBMS_OUTPUT.put_line (l_date);
EXCEPTION
   WHEN no_listner_excep
   THEN
      DBMS_OUTPUT.put_line (SQLERRM (SQLCODE));
END;

Ora-12154 problem with database link and transparent gateway

Hello,
I’m trying to make a communication between oracle and SQL server 2005.
I use oracle 10g E.E Release 10.2.0.3.0 and the transparent gateway for SQL server 10201_gatway_win32.zip.
Install:
The oracle database is installed into a server named ss-serv. This server has two partition disk C and E. Oracle database is installed in E and the gateway in C. There is already a database (instance) running in the oracle home (in E).
I configured the gateway as described into: http://download.oracle.com/docs/cd/B...3/conf_sql.htm.
In sql server 2005, there is a database running named ClientTricks.
I created a user named Avogadro with a login.
In the partition C where the gateway is installed, the file inittg4msql.ora is like this:
HS_FDS_CONNECT_INFO= ss-serv. ClientTricks
The file sqlnet.ora where the gateway is installed is configured like this:
SQLNET.AUTHENTIFICATION_SERVICES=(NTS)
NAMES.DIRECTORY_PATH = (TNSNAMES, EZCONNECT)
I configured the listener that is in the C partition where the gateway is installed, and the tnsnames that is in the oracle database in E partition disk like this:
Listener :
LISTENER=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=ss-serv)
(PORT=1521))
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=tg4msql)
(ORACLE_HOME=C:\oracle\product\10.2.0\tg_1)
(PROGRAM=tg4msql)
tnsnames:
mytg4msql=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=ss-serv)
(PORT=1521)
(CONNECT_DATA=
(SID=tg4msql))
(HS=OK))
After edited the listener, I stop and start the listener for the transparent gateway from administrative tools in the services.
Then, connected in oracle (in a database named fakeclient) I created a database link in sqlplus.The the dblink were created, but when I tried to querry some data from ClientTricks by executing the following instructions:
select * from s_client@dblink
i got this fatal and terrible error :
ora-12154 TNS:could not resolve the connect identifier specified
I verified all my procedure and stapes, all seems to be good. I did a tnsping of mytg4msql
I got this error in the command prompt:TNS-03505 fail to resolve name
Could someone help me ?
Sorry for my English ,I’m French
best regards

Hi Mkirtley,
i clarify you what i've done:
Pease have a look in the link in my first post. Then, i said that in oracle database home the listener is in port 1521
here is this listener:
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=PLSExtproc)
(ORACLE_HOME=E:\oracle\production\10.2.0\db_1)
(PROGRAM=extproc)
LISTENER=
(DESCRIPTION_LIST=
(DESCRIPTION=
(ADDRESS= (PROTOCOL=TCP)(HOST=ss-serv)(PORT=1521))
(ADDRESS= (PROTOCOL=IPC)(KEY=EXTPROC0))
Here is the tnsnames.ora in oracle database home:
N.B in this ora file, there's already some descriptions for the database running, so i just add these lines under the description in ora file.Here is:
Jest=
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=TCP)(HOST=ss-serv)(PORT=2000))
(CONNECT_DATA=
(SID=tg4msql)
(HS=OK)
for the listener of the gateway (installed in C partition):
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=tg4msql)
(ORACLE_HOME=C:\oracle\production\10.2.0\tg_1)
(PROGRAM=tg4msql)
LISTENER=
(DESCRIPTION_LIST=
(DESCRIPTION=
(ADDRESS= (PROTOCOL=TCP)(HOST=ss-serv)(PORT=2000))
(ADDRESS= (PROTOCOL=IPC)(KEY=EXTPROC1))
here are all i did.
Best regards

Query a remote table with Database Links

How do database links work with ODP.NET? The following code produces an "ORA-02041: client database did not begin a transaction" error on the Fill method.
SQL (in acme instance):
CREATE DATABASE LINK sales.hq.acme.com
CONNECT TO scott IDENTIFIED BY tiger
USING 'sales'
VB .NET:
Dim cn As New OracleConnection("Data Source=acme;User ID=scott;Password=tiger;")
Dim da As New OracleDataAdapter("SELECT * FROM [email protected]", cn)
Dim ds As New DataSet
da.Fill(ds, "RemoteEmp")

Just read running procedure on remote db???
Changed first line to
Dim cn As New OracleConnection("Data Source=acme;User ID=scott;Password=tiger;Enlist=false")
and it works now.
That's what I get for searching the forum instead of browsing.

Stored procedure with database link with "from table(...)"

Hi guys,
I've been told I can't create views on a database by the design team and so have to use this stored procedure to obtain the values.
select HAN_ID, HAN_DS, GLOBAL_IN, LOCAL_IN
from table(cast(ODADMIN.ODP00002_QUERY.Execute001@DBLINK(11312,'EN') as
ODADMIN.ODP00002_001_Array@DBLINK)) WHERE LOCAL_IN = 'Y';I've been told that it works when you remove the database links (so on the actual database) when you remove the cast part. I've tried it with my link and with/without the cast part but it doesn't work. With the example above I get the error: ORA-00907: missing right parenthesis.
When I remove the CAST-AS and the additional parenthesis it brings i get the error: ORA-00904: "ODADMIN"."ODP00002_QUERY"."EXECUTE001": invalid identifier
When I do table( *"* ODADMIN.ODP00002_QUERY.Execute001@MWW_DEV(11312,'EN') *"* )... -- wrapping the call in speech marks I get: ORA-00972: identifier is too long
Anyone see what's wrong? Thanks for any help.
Mike

Hi Ben,
Asking now. By a view I mean one local to the database; I could create one on APEX but then I use the database link twice instead of just 1.
His reasoning Ben:
Firstly, Maintenance. We will have to maintain additional views (at additional code). Secondly, if the view has a JOIN, then you can't update through it (without complexities). If we have to get the View to pass the data to a Procedure (that's a pain). Also, standards..
All update occur via either a Procedure, or a Base view, across over 1000 tables
That's the standard, and doing things differently is costly long term
People will not know how it works, it will have to be explained, maintained..etc.
If the Application has the Business Rules, then updates via Base Views, that's a more standard way of developing. Also, if you update via this view, you'll update multiple rows in one call, which is in-effficient if only ONE row needs to change. Therefore, single row updates from the Application is more efficient
The procedure is as follows:
--SET SERVEROUTPUT ON

nPBusLoc       NUMBER(5):=11312;

So what is different between the two databases other than the operating systems they run on? What should I examine?
I should add that the linux PC is Internet facing and has a Public IP address (USB mobile broadband Modem) to which I-Surname.co.uk resolves via (ZoneEdit.com and ddclient).

The problem is that the databases do not work in the same way. As I have said one produces DBLINK.i-surname.co.uk and the other DBLINK. Both machines are members of the i-surname.co.uk domain.
In Sqldeveloper one can not alter the DBLINK since it has a "-" character (.I-Surname.co.uk)
Why the difference?

How can I use SQL TOOLKIT concurrently with Database Connectivity ?

I have installed LabVIEW 6.1 with the Database Connectivity Toolkit and the SQL Compatibility Toolkit (e.g. _SQL folder). I am trying to make the transition from the SQL Toolkit VIs to the Database Connectivity toolkits, but for compatability with existing systems I would like to be able to run the two sets of VIs concurrently (but not in the same app).
When I read into 6.1 a connection VI that I wrote with LabVIEW 6.0 and the SQL toolkit the connection reference type gets changed from a number to type connection (see attachments) . Does compatbility mean that my SQL toolkit VIs are converted to a form compatible with the new ADO ?
Can I use the SQL Toolkit VIs or the Database connectivit
y VIs in the same installation of 6.1 ?
Can I have the SQL Toolkit VIs appear on the functions pallette and function as they did when only the SQL toolkit was installed ?

In response to your #2 below:
Actually it is possible to have the old SQL Toolkit and new Database
connectivity in the same installation of LabVIEW. I have only tried it on
6i, but don't see why it wouldn't work on 6.1. The trick is not to install
the SQL toolkit compatabitily VI's. The old SQL toolkit uses the Intersolve
dll through ODBC while the new Database connectivity uses ADO so it is
possible to use both methods not only in the same LabVIEW install, but it
the same running application. It has been a while since I originally did
this, so I am posting only to mention that it is possible and not exactly
how to do it. If anyone is interested in more details just respond.

SQL Developer create wrong SQL for creation of Database link

Hi,
I tried to create Database link to another machine through SQL Developer. and I got error message saying "Sql not properly ended" or similar.
I copy-paste the sql to sqlplus shell and I found that the problem came from password part of database link so the generated from SQL Plus is something like:
SQL> CREATE DATABASE LINK mytest CONNECT TO anotherDB IDENTIFIED BY 1234 USING 'OtherServiceName';
but it should be
SQL> CREATE DATABASE LINK mytest CONNECT TO anotherDB IDENTIFIED BY "1234" USING 'OtherServiceName';
so if I type in the password field
"1234" which is ****** /6 chars/ the database link was created correctly.
Could you check and fix this in next release of the SQL Developer?
Otherwise the Application is very good and far ahead from TORA :)

Thanks, I didn't notice that for passwords. So it's most definately my problem that the SQL Developer . :)
Thank you for clarification!
Offtopic: I am searching for DB Comparison tool which could compare 2 schemas and return me the differences and the sync script. Do you know any /free if possible/? There is such thing in TOAD but I am on Linux and I prefer to use something else. :)
Thank you in advance

Issue while creating location with database link

Hi all,
I am using OWB 10.2.0.4.0 (same Oracle DB version). I am trying to create a location using a database link.
When I select the location which the database link is located (From location drop-down list), I face the following error.
>
ENV0036: The selected location is not valid.

Could you please let me know how to solve this and how to create such location with OMB*Plus?
Thanks,
Sebastian

Hi David,
Thanks a lot for the tip. Now I was able to use this and using a registered location.
OMBCREATE LOCATION 'X' SET PROPERTIES (TYPE,VERSION,CONNECTION_TYPE, SCHEMA) VALUES ('ORACLE_DATABASE','11.1','DATABASE_LINK','MY_SCHEMA')
OMBCREATE CONNECTOR 'REGISTERED_LOC/X SET PROPERTIES (DATABASE_LINK_NAME) VALUES ('MY_DBLINK') SET REF LOCATION 'X'
OMBCOMMIT
OMBCC '/MY_PROJECT'
OMBCAC 'DEFAULT_CONFIGURATION'
OMBCONNECT CONTROL_CENTER USE 'owb_user/owb_user'
OMBREGISTER LOCATION 'X' REUSE
OMBCOMMITBut now my question is the following.
I am having problems to import the metadata from X.
When create a module (source), I am able to make "data location" from location 'X' but when I want to import a table from location 'X' is not possible, because it shows as a plausible metadata location as "REGISTERED_LOC"
Could you please let me know how to use 'X' as metadata location?
Thanks!
Sebastián

How to register a Location with database link in Ombplus?

Hello,
what's the detailed syntax in owb 10.2 to register a location with a database link?

Hi,
thanks that helps.
Now i found out that after an import of the location the field "from Location" is not set. I need to set it to OWB_REPOSITORY_LOCATION.
How can i do it?
OMBALTER LOCATION 'Locname' SET PROPERTIES (FROM_LOCATION) VALUES ('OWB_REPOSITORY_OWNER') does not work
-> Property FROM_LOCATION is not defined in class ORACLE_GATEWAY_LOCATION
Cann you help me again?
Thanks
Helga

Problems with Database Link in query

When I run this code:

ORA-00904: "SETUP"."SITE": invalid identifier
ORA-02063: preceding line from THE_LINK
However, if I remove any of the cmd1, cmd2, fedlog, mdms, or ammo joins, it runs properly.
It also runs properly if I remove both "WHERE h.data_dt BETWEEN '01-SEP-06' AND '31-OCT-08'" (line 25) and "AND x.pmc_cancel_fg = 'F'" (third line from the end).
Also, there are three different external sites; the problems happen on two of them, but on a third, the code works as is.
The query also works if:
* I remove the links and run it directly on the external sites
* I add something that makes it return no rows immediately (for example, "AND 0 = 1" as the last line)
* "WHERE h.data_dt BETWEEN '01-SEP-06' AND '31-OCT-08'" is replaced by "WHERE h.data_dt = '30-SEP-09'" (which returns rows)
* For that matter, at one of the problem sites, changing the first date in that WHERE clause to anything between '19-JUN-09' and '29-SEP-09' works, but '18-JUN-09' and earlier causes the error; at the other, the earliest working date is '02-NOV-08'.
All three external databases, as well as the database on which this is run, are running 11.2.0.1.0 64-bit Production.
Any ideas as to what is happening?

'This is a string, 2009-12-31, not a date'
When a DATE datatype is desired, then use TO_DATE() function.Actually, usually I do (since there's no guarantee as to what the "default" date format will be - besides, the default tends to be 2-year dates). The one line where I don't is really just something I added to speed up the query when testing for the error.
However changing that line to:
WHERE h.data_dt BETWEEN TO_DATE('09/01/2006', 'MM/DD/YYYY') AND TO_DATE('10/31/2008', 'MM/DD/YYYY')causes the same results.
