Adding REDO_Collector and Error:ORA-02082: a loopback database link...

Hi, when I tried to add REDO Collector by command
avorcldb add_collector -srcname av_db -agentname avagent -colltype REDO -av hostname:port:service name
I got following:
Collector added successfully
Collector name (collname): REDO_Collector
ERROR: ORA-02082: a loopback database link must have a connection qualifier.
Any idea...? Please..

i tried using -srcuser and i am getting the following error message
avorcldb add_collector -srcname ORCLDB -agentname ORADB_AGENT -colltype REDO -srcuser av_user -av oraods.domain.com:1532:ORCL.WORLD

Report error: ORA-02020: too many database links in use

I am getting error ORA-02020 in a report that works exactly the same in other APEX instance.
The query refers several tables from Oracle Financials with a single database link.
The weird thing is that for some parameters the report shows the expected lines, and for other parameters it shows the error message.
There are three other regions in the same page running grouped versions of the same query and they work perfectly.
Any idea will be welcome.

Why i receive errors: "The procedure entry point longjmp could not be found in the dynamic link lib. orauts.dll" and "Error ORA-12560"

Hello,
"C:\app\xps\product\11.2.0\dbhome_1" where is my installation of database oracle enterprise 11g; I use Windows 7 Pro.
I have in System PATH : C:\app\xps\product\11.2.0\dbhome_1\bin
I have in HKEY_LOCAL_MACHINE > SOFTWARE > ORACLE > SYSMAN > OracleDBConsoleorcl : "ORACLE_HOME" value "C:\app\xps\product\11.2.0\dbhome_1"
When i execute "sqlplus / as sysdba" command, i receive error: "The procedure entry point longjmp could not be found in the dynamic link lib. orauts.dll" and "Error ORA-12560"
If i execute
set ORACLE_HOME=C:\app\xps\product\11.2.0\dbhome_1
C:\>set PATH=%ORACLE_HOME%\bin;%PATH%
sqlplus "/ as sysdba"
I don't receive Error.
Why?

You don't mention which specific version of the operating system that you are using - Windows XP, Vista, or 7 and whether you're using a 32-bit or 64-bit version.
FWIW, kernell32.dll is a Windows system-level module, so it's possible that you have some corruption in your Windows installation which is preventing FM from launching.
Also, 2Gb of RAM is a bit lean for FM.

ORA-02020: too many database links in use ; but OK with where clause...

Hello all,
I have a view called V_MEDGEN_LISTRADIO but I can't run
SELECT * FROM V_MEDGEN_LISTRADIO
ORA-02020: too many database links in useThe cause is that we call in the view 5 tables over dblink and the open_links parameter is set to 4.
What is strange is that when I run this select by adding a where clause then it works!
SELECT * FROM V_MEDGEN_LISTRADIO WHERE SPRR = 3645;Can someone explain me ? (use of index so all tables are not called ???)
Thanks

Explain plan for SELECT * FROM V_MEDGEN_LISTRADIO WHERE SPRR = 3645;

ORA-02020 too many database links

Hello,
I'm getting the ORA-02020 too many database links error in my Apex application. This error occurs when I run an interactive report in a page. There are 21 pages and 7 database links in the application. Each page has one interactive report that references one database link in the region source.
The database links are referenced in each page as follows: database link1 (page 1); database link2 (pages 2 and 3); database link3 (pages 4-7), database link4 (pages 8-15); database link5 (pages 16-18); database link6 (pages 19); and database link7 (pages 20-21). Each database link is referenced to separate schemas in one remote Oracle database.
I tried to eliminate the error by setting the open_links and open_links_per_instance parameters in the init.ora file of the remote and XE databases to 100 then restarted the both databases. This solution did not work. I created separate Application Processes from the Shared Components to close each database link by implementing the following:
Click on Shared Components> Logic > Application Processes > Create >
Name: CLOSE_LINK1
Sequence: 1
Point: On Load: Before Header (page template header)
Type: PL/SQL Anonymous Block
Process Text: execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
Error Message: Database Link Error
When I run the application now, the ORA-02081: database link is not open error appears.
Please help anyone! I know someone has experienced these same errors.
Thanks,
Ms. H

Joel,
Thank you for your quick response. For clarification purposes, could you provide samples for 1) issuing the CLOSE DATABASE LINK and catching the exception; and 2) querying from V$DBLINK prior to issuing the CLOSE DATABASE LINK from the Shared Components > Logic > Application Processes?
Lets assume the following query with a database link in the region source is referenced for Page 1.
Page 1 - Employee Listing
Region Source:
select ename, job, hiredate
from scott.emp@link1
Lets assume the following Application Processes from the Shared Components is referenced to close the database link:
Click on Shared Components> Logic > Application Processes > Create >
Name: CLOSE_LINK1
Sequence: 1
Point: On Load: Before Header (page template header)
Type: PL/SQL Anonymous Block
Process Text: execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
Error Message: Database Link Error
My thoughts are to do the following:
1. Log in SQL*Plus as SYS
SQL> grant select to v_$dblink to scott;
2. In Apex, goto Shared Components> Logic > Application Processes and add the following queries in the Process Text:
Name: CLOSE_LINK1
Sequence: 1
Process Text:
select db_link from v$dblink;
execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
3. Catch the exception???
Your assistance is greatly appreciated. :8}

FOR UPDATE on scrollable cursor and error: ORA-00907: missing right parenthesis

If change my query to have a FOR UPDATE and make it an updatable scrollable cursor I get an error on the updateRow() command saying "ORA-00907: missing right parenthesis"
If I remove the FOR UPDATE it works OK.
The problem I have is trying to update a CLOB from a ResultSet. If I do not upate any other column I get the error saying that the error"
"ORA-22920: row containing the LOB value is not locked"
I can get around this by adding FOR UPDATE. But if I add FOR UPDATE and try to update any non-CLOB column I get the 00907 error above.
Hmmmm. So here is what I can and cannot do:
- I CAN update the CLOB IF I update another column 1st and NO FOR UPDATE clause.
- I CAN update the CLOB only if I have FOR UPDATE clause.
- I CANNOT update just the CLOB without FOR UPDATE.
- I CANNOT update any non-CLOB column with FOR UPDATE.
What a pain in the ***! How am I to provide generic access to the applications being built on my DB layer. This is crazy!

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Andrew Edgar ([email protected]):
I have this same problem!
The error occurs when performing updateRow.
The turning off of auto commit only gets the query to work but not the actual update.
Will this be fixed in the next version of the Driver?<HR></BLOCKQUOTE>

10g Installation and Error : ORA-12514 : Listerner cant recog. service requ

Hi,
I installed 10g, and trying to start sql plus. I entered
username: orcl
password: my own password
host string: name of my computer
I am getting the error: ORA-12514: TNS: Listener does not currently know of service orequested in connect descriptor.
I started the services and tried again but same problem.
I also tried system and sysman as username, w/o a password and included my computer name, but still facing the same problem.
Any thing else I should do besides uninstalling and reinstalling ?
Thanks

Where did the user name orcl come from? It certainly is not going to be there unless you logged in with a DBA account and created it: Did you?
So back to basics ... what version of Oracle did you install? 10g is a marketing label not a version number. It is likely something between 10.1.0.2 and 10.2.0.4.
Second how did you install the database? With the Oracle Universal Installer or with a script? Were there any error messages?
Have you checked the installation log?
Has it ever worked in the past and is now broken or has it never worked?
Is the listener running? How did you check?
When you say "I started the service" you are in what operating system and you started what service and how?
My guess, and it is only a wild guess given how little information you provided, is that there is an issue in your listener.ora and/or tnsnames.ora files: Post them along with the value you are entering as "Host" when you try to log in.
Again just a guess ... the user name should be SYSTEM, the password whatever you entered, and the Host "orcl."

National Language Support and Error ORA-01858

Hi,
I have a problem using NLS.
When I use NLS for Italian,I become the error ORA-01858 -->
"a non-numeric character was found where a numeric was
expected".
But with the same query I use for NLS_Italian,it works with
NLS_German and NLS_English.
I use this date-formats "DD.Month YYYY" , "DD.MM.YYYY", "DD.MM"
For example:
Select to_char(sd.Datum,'DD.Month YYYY') Datum ,
sd.FONDSVERMOEGEN, sd.AKTIEN, sd.KASSE, sd.RENTEN,sd.FUTURES,
sd.WERTPAPIERE, sd.IMMOBILIEN,

Strukturdaten sd,fondsdaten_allgemein fd
where sd.match=fd.match and sd.match=amfcomm .
Can somebody help me??

Can you tell us what the value of sd.Datum is in the queries?

ERROR:
ORA-02019: connection description for remote database not found

Metalink Note:262881.1
The information in this article applies to:
Oracle Server - Enterprise Edition - Version: 8.0.x to 9.2.0.x
This problem can occur on any platform.
Errors
ORA 2019 connection description for
Symptoms
Describe on a Synonym which is based on a database link may issue error:
ORA-2019 connection description for remote database not found
Select from the synonym works successfully.
Cause
Based on the Bug 3071468 this issue happens when the local
and the remote database have different domain name in the GLOBAL_NAME.
For example if:
select * from global_name;
gives from local database:
PROD.UK.ORACLE.COM
and the remote database has:
TEST.US.ORACLE.COM
then we have different domains for the global_name.
This does not reproduce when the domain is the same for both global_names.
Fix
This issue is fixed in 10.1.0.2.
For previous versions we have the following 2 workarounds:
1. Use View in the place of the synonym. This works.
2. Alter one of the databases global_name , so that the 2 global_names to have the same domain.
For example in the above example chenge the TEST database as:
sql> alter database rename global_name to test.uk.oracle.com;
Then you would have to drop and recreate the database link.

Import and error ora-12203

Hi,
I got this error ora-12203 (TNS:unable to connect to destination) when I was importing a table into my own schema. I don't know whether the error is related with import. My question is: when performing import, can other user login into the database?
Thanks,
Richard

Hi Richard,
The database will you to logon irrespective of what other work you are doing with whatever tool you are using. The Exceptions are :-
If the refered schema comes under certain restriction of the assigned profile.
If the database is running in RESTRICTED mode and you are not having accessibilty during this peiod.
As for your error in the import statement, check the connection you are using in the import statement.
I'm personally using import at least 10 times a week and usually come across these errors. These errors are all human errors and not bugs in the program.
Bye,
Piyush.

SQL Loader and Error ORA-01847/ORA-01839

Hi,
While using the direct loading in SQL-LOADER when we get the ORA-01847/ORA-01839 all the other records are getting errorred out. It goes fine with the conventional loading.
Should I use some parameters or anything to make sure that all the other records are not rejected when we get the ORA-01847/ORA-01839 error while going with the DIRECT loading.
Thanks
Jibin

In internet I found this short message:
“AL32UTF8 is a multi-byte characterset,that means some characters are stored in more than 1 character, that's true for these special characters.
If you have same table definitions in both databases you likely face error ORA-12899.
This metalink note discusses this problem, it's also applicable to sqlloader:
Import reports "ORA-12899: Value too large for column" when using BYTE semantic
Doc ID: Note:563893.1”
By metalink, I can see the Note linked to a one Oracle Internal Bug for Oracle 11g.....
I'm waiting you suggestion... thanks very much in advance.

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

Ora-02020 too many database links in use

Hi All,
While trying to update Table through datalink in my program I am getting the above error. Without modifying the v$parameter value ( 'open_links' ) in database how to use this feature to close Inactive sessions in BPEL ?

Yes, I set the init.ora parameters on all servers and then restarted them. I still get the error.
Note that, for convenience, all my servers have public database links to all other servers in my private network.
This procedure (described at the start) works for one run of copying 50 tables from one server to one other server:
server1 runs the procedure and copies data from server2 to server3 (total of 3 servers in the process)But I get the error when I run the procedure to copy 40 tables from multiple servers to one other server:
server1 runs the procedure and copies data from server2, server3, and server4 to server5The error occurs when only four (or five) servers are involved in the process.
Any suggestions are greatly appreciated.

ORA-12154 when using Database Link

We're running 11r2 on our servers. I have a primary db and a standby db, using Data Guard. The standby is open for read-only querying. We are not using ASM.
The primary (and thus the standby) have a PUBLIC database link to a third db server.
When I run a query against the database link on the primary: select * from test@MyDBlink; Everything works fine.
When I run the same query against the database link on the standby: select * from test@MyDBlink; I get ORA-12154: TNS:could not resolve the connect identifier.
I check that the db link exists on the standby. It does.
I go to command prompt on the standby and run "tnsping MyDBlink". It executes fine. It says "Used TNSNAMES adapater to resolve the alias" and sure enough, MyDBlink is referenced in the TNSNAMES.ORA.
I also run "tnsping IP-of-MyDBlink" to doublecheck. No issues.
What is going on that is blocking the db link on the standby? Many reports utilize that standby and I'd hate to deny them the functionality of a db link.
Thanks

ThanksMost people with this problem don't understand that the dblink is just another client, no different than sqplus running on the same machine - and therefore the link uses the tnsames in the ORACLE_HOME of the database containing the link. But it seems from the steps you've described that you've grasped that. The only thing I can think of off the top of my head is when you try sqlplus from the standby server you are hitting a different tnsnames than the one the database is using.

Adding REDO_Collector and Error:ORA-02082: a loopback database link...
