I've gotten past this by creating the dblink as SHARED.
The SQL is
CREATE SHARED DATABASE LINK "yourlink"
CONNECT TO "dbuser" IDENTIFIED BY "dbuserpassword"
AUTHENTICATED BY "dbuser" IDENTIFIED BY "dbuserpassword"
USING 'databasename';
note the quote character use.
You can also use SQL Developer to adjust this.
This does depend on shared database connections between your db's.

Use of non-migratable database link not allowed ERROR

Hello,
We have a notification process (on disabled user) in OIM that needs to connect to a schema in another instance to check some information before the notification is sent out.
We have OIM in an instance A and the other schema lives in the instance B. We created a database link from A to B, some synonyms, and grant the right permissions for OIM to select the tables in the schema on instance B.
We can login to OIM using SQL Developer and execute the query without any problems.
However, when the query is executed in the Disable User process task, we got the error:
java.sql.SQLException: ORA-24777: use of non-migratable database link not allowed
We tried to create a view in OIM that is similar to the one that lives in the schema in instance B. However, the same error exists.
How can we work around this error?
Thanks

with all the info you have put here all I can say is : (with some help from google ;-) )
ORA-24777: use of non-migratable database link not allowed
Cause: The transaction, which needs to be migratable between sessions, tried to access a remote database from a non-multi threaded server process.
Action: Perform the work in the local database or open a connection to the remote database from the client. If multi threaded server option is installed, connect to the Oracle instance through the dispatcher.

The code I'm using to do the parseing is:
// Parse the CNet XML into a proper doc.
DOMParser parser = new DOMParser();
parser.parse(new InputSource(new StringReader(cnetSpecs)));
org.w3c.dom.Document cnetXml = parser.getDocument();
xmlUtil.toFile(cnetXml, "/tmp/cnetxml.xml");
NodeList cnetRoot = cnetXml.getElementsByTagName("CNetSpecs");
Node CNetStatsNode = xml.importNode(cnetRoot.item(0), true);
root.appendChild(CNetStatsNode);and I get the following errors:

I've been scratching my head all day.

I dont think so that it is because of un-escaped "&" character or breaking line sequences.
As in mine case it is giving for XML as below:
<?xml version="1.0" encoding="UTF-8"?>
<publicationManifest date="03/13/2007 14:06:25">
<contentItem action="add" expireDate="" releaseDate="" revision="1">
<content>This would go under webstore</content>
<metadata>This would go for Database</metadata>
</contentItem>
</publicationManifest>
and console output at java IDE is
[Error] item-manifest_Test.xml:4:46: s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'. Saw 'This would go under webstore'.
[Error] item-manifest_Test.xml:5:45: s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'. Saw 'This would go for Database'.
Therefore , if anyone had found the root cause of this discrepancy please update this topic.

Switchover_status in standby database showing NOT ALLOWED

Hi All,
My oracle database version is Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit on windows platform.
I need to perform switchover activity with dg_broker=TRUE.
When I checked the status of DR database I found that switchover_status is NOT ALLOWED rather than SESSION ACTIVE or TO PRIMARY.I have doubt whether switchover can be done successfully or not with this configuration?

1.In this case,is switchover is possible?No
2.If not possible then what will be the next step?If the value in the SWITCHOVER_STATUS column is SESSIONS ACTIVE, identify and terminate active user or SQL sessions that might prevent a switchover from being processed.
If, after performing these steps, the SWITCHOVER_STATUS column still displays SESSIONS ACTIVE, you can successfully perform a switchover by appending the WITH SESSION SHUTDOWN clause to the
ALTER DATABASE COMMIT TO SWITCHOVER TO PHYSICAL STANDBY statement.
3.Is this will impact to our production database when switchover is not successfully perform?
4.In DR RFS is idle,why?Can you paste here log_archive_dest_n paramete which is you are using for transport?
Did you using DELAY attribute in log_archive_dest_n parameter?

Database Link not Active

I am trying to create a database link from Oracle 7.3.4 to Oracle 8i. When I click the "Test" button in OEM ( after entering the relevant data) I am getting an error that reads "Database Link not Active". What am I doing wrong? can someone help?

Hi ,
Thanks again for your quick and extremely helpful response.
As you have guessed this is my clients tnsname.ora file. From your response i believe i need to check the tnsnames.ora file of the database itself ( i assume it resides in the server box).
I used the same exact systax for creating the link and the link was successfully created. But i was not able to access any table and was getting the error "TNS: could not resolve service name." Now i understand that the 7.3 server is not able to connect to the 8i, as it does not know of its existence (as there is no information available in its own tnsnames.ora file). Am i right?
Thank you once more.
You will make my day (assuming i understood you right.)

VLD-2769 DB link not allowed error

version: OWB 10.1.0
situation: target dimension object doesn't reside in same schema as mapping.
error: VLD-2769 DB link not allowed for target table
Is there a way to use Public Synonyms or something else to overcome this problem in OWB without having to place the mapping in the same schema as the dimension object or say a table.
Thank you

thanks for the reply
I have a db link for it but I don't think that's the problem, I even have a public synonym for the table.
Oracle tells me that they dont support mapping in one schema calling a target object in another schema, BUT they said there was a workaround.
that is what I am trying to find out....
thanks

As a new Macbook Pro user I was saddened to find that the feature of using keywords in iPhoto '11 does not allow showing same under each photo. I understand this was available in earlier versions. Any comments?

Can Jdeveloper Be Used For Non-Oracle Databases

I have been trying to evaluate Jdeveloper 9i and Jbuilder 7 Enterprise for Swing database development. I am particularly interested in the productivity enhancements such as BC4J and Jclient. The underlying database might be Oracle, SapDb (excellent, easy to use, and free), SQLServer, etc.
I evaluated Jbuilder Enterprise tools and it worked flawlessly with SapDb. This emphasized using their DataExpress and DbSwing components which provide many useful capabilities similar to BC4j and Jclient. It also involved using their DBPilot tool which allows browsing similar to that provided via a Jdeveloper connection.
I tried to use Jdeveloper for the same SapDB and it is essentially non-functional. I followed the instructions for using a non-default driver and tried to define a connection. It behaved inconsistently: often saying no suitable driver can be found and yet when you edit the connection and test without making any changes, it works. If you try to establish a BC4J definition, it is very inconsistent and fails to recognize important details as foreign keys. Even if you define a ViewLink manually, it still does not work properly if you attempt to define a Master-Detail Jclient form. As I have stated, all these types of capabilities worked flawlessly in their Jbuilder equivalent. Furthermore, I really like the fact that Jbuilder gives many of BC4Js benefits without needing a BC4J J2EE container.
Has anyone had real success using Jdeveloper's advanced features to develop for non-Oracle databases and if so, how did you get around these types of problems?

Hi,
generally, SCAN can be used for 10g databases and you discovered the first half: for 10g databases you will have to modify the REMOTE_LISTENER entry for each 10g database instance to point to the SCAN listeners (as opposed to pointing to the remote local listeners, which is the default in 10g). You could even have the databases registers themselves with SCAN and the remote listeners, if you wanted to... It's more or less a matter of configuration. But for simplification reasons, I will stick to the case where you have your 10g databases register with the SCAN listeners only.
Now the other half is the client and the client configuration. An 11g Rel. 2 client configured for RAC would have a TNSNAMES entry that has only one address line for the RAC databases. The host entry in this one address line should point to the SCAN (the SCAN name is ideally resolved in DNS). A 10g client configured for RAC would have as many address lines in the TNSNAMES as you have nodes in the cluster.
The 10g client SCAN configuration would then be in the middle so to speak: You would have 3 address lines in your TNSNAMES, in which each host entry would resolve to one SCAN address (I assume you will use the recommended default of 3 SCAN IPs). If you choose, you can have a name resolution for each of your SCAN IPs, but this would not be required. Now, why would you do it this way? Because this configuration will always work and does not make you dependent on certain functionality that your DNS server may or may not offer.
For the remaining questions: SCAN is a DNS entry resolving one name to more than one (typically 3) IP addresses. OID is short for Oracle Internet Directory, which is a complete LDAP server. And you are right that there is no document how to configure 10g clients for SCAN from Oracle yet. However, there is a quite good document on SCAN on otn.oracle.com/rac, but I am sure you are aware of it already.
Hope that helps. Thanks,
Markus

Database Links not generated

In OWB 9i, the database links are not generated as part of the mapping anymore. My problem is that I create a new source module and then a mapping using this source module, but it does not generate the code for the database link. When I deploy the mapping it says the database link does not exist, but it does not provide the code for generating the links. Am I missing something? I would appreciate a fast response, since I'm currently giving the OWB course and have to show the students the new 9i features tomorrow (Thursday 15 Aug)! Thanks!!

Hi Marlene,
You can get the database link DDL when you generate the Warehouse Module as a whole, open the Warehouse module editor and highlight the Warehouse module, right click and generate. In the generation results filter on DB links and review the scripts, deploy these in the schema where you want to install the mappings.
To create new db links, go to configuration on the warehouse module where you need to links, in there choose the last entry (database links). This also allows you to delete the ones you don't need.
Hope this helps,
Jean-Pierre

Using generic format for database links in ODI Procedures

Hi,
As in procedure we use
create table <%=odiRef.getSchemaName("Target Schema","D")%>.TABLE2 as
select * from <%=odiRef.getSchemaName("Staging Schema","D")%>.TABLE1
where Staging Database and Target Database are logical schemas which will associate to respective physical schema while execution so the above statement will become as
create table Target_Schema.TABLE2 as
select * from staging_Schema.TABLE1
I just wanted to know if there is any way by which i can apply samethings for Database Links also.
Like if i have statements
create table TABLE2@Target_Database as
select * from TABLE1@staging_Database
can i replace DB links like Target_Database and Staging_Database?
Help would be appreciated. :)
Thanks,
Mahesh

I am not entirely sure about the exact requirement.
Any way ..
1.
create 2 variable .
v_get_src_schema : select '<%=odiRef.getSchemaName("<your_src_logical_schema>","D")%>' from dual
v_get_tgt_schema : select '<%=odiRef.getSchemaName("<your_tgt_logical_schema>","D")%>' from dual
2.
2 more variable to get the required DBLink
v_SRC_DB_LINK: select DB_LINK from all_db_links where owner='#PRJ_CODE.v_get_src_schema'
v_TGT_DB_LINK: select DB_LINK from all_db_links where owner='#PRJ_CODE.v_get_tgt_schema'
3.
create a procedure :
prc_create_table :
create table <%=odiRef.getSchemaName("Target Schema","D")%>.TABLE2@'#PRJ_CODE.v_TGT_DB_LINK' as
select * from <%=odiRef.getSchemaName("Staging Schema","D")%>.TABLE1@'#PRJ_CODE.v_SRC_DB_LINK'
4.
Create a package :
Connect all the steps in serial with OK line.
Execute and let us know what is the out come .
Thanks,
Sutirtha

Database link not working properly

I have to link to another database...I have created an entry in my TNS names on the oracle server and have used the following script to create the link:
CREATE PUBLIC DATABASE LINK DATA
CONNECT TO USERNAME IDENTIFIED BY PASSWORD
USING 'DATA';
Data is the name of the database sid, and I am able to connect to the server using the username/password@sid in sqlplus. Oracle tells me that the link is created successfully, however if I try to describe user_tables@data I get the following error:
SQL> desc user_tables@data;
ERROR:
ORA-02085: database link DATA connects to DATA.WORLD
Please help!
Jes

You will see this error when the global name of the remote database does not match what you have in your link. Although the link name might match the SID, the fully qualified link name does not.
You can either:
1) Set the GLOBAL_NAMES parameter to FALSE in the database in which you have created the database link.
2) Recreate the link so that the full link matches the global name of the remote db (query GLOBAL_NAME in the remote db if you don't know it)
Good luck!

Database link not working

Hi,
I created a database link and i added a tns entry also. But when i try to connect to a database using db link it throws me an error

Thanks and Regards
Jafar

please check the username which is using Db link.. is it same which you have db links created.
