Oracle RAC with Admin tools

Hello!
I use Weblogic Server 10.3.2. I have a portal application and I want to manage the content with Portal Administration Console from admin-tools.war . Admin-tools is a part of my portal application. I eclipse I check for my ear project on Project Facets : Admin Console, Admin Framework, Portal Application Services, Portal Customizations Framework.
I have a cluster with two servers. As a database I use Oracle 10 with two instances : instance 1, instance 2. I have created my domain with wizard and I checked RAC Multidatasources.
All datasources and multidatasources are targeted to my weblogic cluster, also where is deployed my app and Portal Administration Console ( admin-tools.war).
I use the multidatasources :

Oracle AQ with Orion 2.0 application server

Hi,
I'm trying to use Oracle AQ/JMS as queue for a J2EE message driven bean running in an Orion 2.0 application server.
To connect the bean with the queue I have to configure a resource provider. By now, the only resource provider I found is the class oracle.jms.OjmsContext witch is included in the oc4j.jar file of oracles J2EE container.
So the question is, is there a way to use Oracle AQ as infrastructure for message driven beans with other J2EE servers then Oracles OC4J?
Thanks in advance.
Alexander Schulz

Tanks 327 for your reply.
I think you got me a little wrong (because of my poor english).
I hoped that somebody can tell me if there is a java library (jar) that I can use to use Oracle AQ with Orion 2.0 for message driven beans.
I'm wondering why the class OjmsContext is only availiable in the main jar of the Oracle J2EE container. I think it would be very usefull to have an extra library containing all the stuff needed to use AQ with other application servers.

Oracle XMLType with CMP EJBs

Hi!
I am currently trying to use Oracles XMLType with EJBs. Preferrably I would like to use CMP. Although the documentation http://e-docs.bea.com/wls/docs81/jdbc_drivers/oracle.html#1067224
says that XMLType is mapped to a CLOB, I get an error
ORA-00932: inconsistent datatypes: expected NUMBER got CLOB
when trying to update it. (I marked the bean as dbms-column-type OracleClob). If I do not mark it as OracleClob, I get an SQLException invalid type sqlType=2007 .
Is there another way to make XMLType work?
Thanks so much,
Hans-Peter Stoerr
PS: We are using Bea Weblogic Portal 8.1, but might migrate to 9. The driver is the oracle thin driver with oracle 9.2.

Hi Brian,
Im not sure whats the issue with using DB Triggers. You could possibly have another
column(s) for created_by and updated_by and still use triggeres for the create_time
and update_time.
Inheritance would make it better if u have multiple tables which need the same
behaviour but the above solution maybe the easy one.

Is there any kind of design pattern for this? I've been searching the

about this. I can't use DB triggers because our application connects

I'm trying to use inheritance as well, have a 'base' object that has

Another issue is how would I trigger setting these columns? Do I have
to store
all the column values in ejbLoad and compare them in ejbStore? I've also

Problem when trying to refresh oracle screens with latest data

hello experts,
i have one problem,i want to refresh the oracle screen with the latest data from the data
base.
It is a two stage process.At first step one user will select a row from the screen and then he will press a button .
now the second screen will appear and the detail of the employee will be displayed.
First step has been completed and the data is coming in the second form via parameters and i can see the full information of the employee.
Now i want to refresh the oracle form i.e. suppose if my dba has made any changes in the oracle table( EMP table) i want that after pressing the refresh button user can see the
latest data from the database.
in WHEN_BUTTON_PRESSED trigger i have written this codes.
enter_query;
execute_query;
but they are not giving the expected result.
And one more thing please suggest whether in the second form i should use database item
or non database item.
When i am using database item when i am trying to close second from one pop up is appearing
and asking that whether i want to save the changes.
please suggest how can i remove this message from my application.
Regards
Anutosh

Hi,
what data did you transfer via parameters to the second form ?
how did you populate the datablock in the second form ?
Typical solution would be:
(For my example the block is both forms is named EMP, and is based on the table SCOTT.EMP)
In Form 1, transfer the primary key-value of the current record to a global or parameter (will use global in my example):
e.g. you have a WHEN-BUTTON-PRESSED-Trigger with the following code:
<pre>
:GLOBAL.EMPNO:=:EMP.EMPNO;
CALL_FORM('FORM2');
</pre>
In Form 2, you have a WHEN-NEW-FORM-INSTANCE-Trigger with code:
<pre>
DEFAULT_VALUE('GLOBAL.EMPNO', NULL);
IF :GLOBAL.EMPNO IS NOT NULL THEN
GO_BLOCK('EMP');
EXECUTE_QUERY;
:GLOBAL.EMPNO:=NULL;
END IF;
</pre>
On block EMP in Form 2 there is a PRE-QUERY-Trigger with following code:
<pre>
IF :GLOBAL.EMPNO IS NOT NULL THEN
:EMP.EMPNO:=:GLOBAL.EMPNO;
END IF;
</pre>
And at last, in your refresh-button would be the following code:
<pre>
:GLOBAL.EMPNO:=:EMP.EMPNO;
GO_BLOCK('EMP');
EXECUTE_QUERY;
:GLOBAL.EMPNO:=NULL;
</pre>
Hope this helps

How to use Oracle partitioning with JPA @OneToOne reference?

Hi!
A little bit late in the project we have realized that we need to use Oracle partitioning both for performance and admin of the data. (Partitioning by range (month) and after a year we will move the oldest month of data to an archive db)
We have an object model with an main/root entity "Trans" with @OneToMany and @OneToOne relationships.
How do we use Oracle partitioning on the @OneToOne relationships?
(We'd rather not change the model as we already have millions of rows in the db.)
On the main entity "Trans" we use: partition by range (month) on a date column.
And on all @OneToMany we use: partition by reference (as they have a primary-foreign key relationship).
But for the @OneToOne key for the referenced object, the key is placed in the main/source object as the example below:
@Entity
public class Employee {
@Id
@Column(name="EMP_ID")
private long id;
@OneToOne(fetch=FetchType.LAZY)
@JoinColumn(name="ADDRESS_ID")
private Address address;
EMPLOYEE (table)
EMP_ID FIRSTNAME LASTNAME SALARY ADDRESS_ID
1 Bob Way 50000 6
2 Sarah Smith 60000 7
ADDRESS (table)
ADDRESS_ID STREET CITY PROVINCE COUNTRY P_CODE
6 17 Bank St Ottawa ON Canada K2H7Z5
7 22 Main St Toronto ON Canada L5H2D5
From the Oracle documentation: "Reference partitioning allows the partitioning of two tables related to one another by referential constraints. The partitioning key is resolved through an existing parent-child relationship, enforced by enabled and active primary key and foreign key constraints."
How can we use "partition by reference" on @OneToOne relationsships or are there other solutions?
Thanks for any advice.
/Mats

Column not found error while populatin a oracle table with ODI USer

Hi,
I am trying to populate a column in a oracle table with the ODI USER name using the function getUser("USER_NAME") in the Mapping column of the Interface, But the interface throwhing an error *Column not found : Supervisor in Statement [Select......]*. but it's working fine with getUser("I_USER') the column is populating the user identifier.
can any one help me out why user is not populating.

Enclose the call to the getUser api inside single quotes
'<%=getUser("USER_NAME")%>'ID being a number can be used directly but USER_NAME returns a string that needs to be quoted

Uploading a file (.doc, .xls, .txt) into an Oracle table with BLOB column

Hello All :
I have been trying to figure out for a simple code I can use in my JSP to upload a file (of any format) into an Oracle table with a BLOB column type. I have gone through a lot of existing forums but couldnot find a simple code (that doesnot use Servlet, for eg.) to implement this piece.
Thanks a lot for your help !!

Hi.
First of all to put a file into Oracle you need to get the array of bytes byte[] for that file. For this use for example FileInputStream.
After you get the byte array try to use this code:
        try {
            Connection conn = myGetDBConnection();
            PreparedStatement pstmt = conn.prepareStatement("INSERT INTO table1 (content) VALUES(?)");
            byte[] content = myGetFileAsBytes();
            if (content != null) {
                pstmt.setBinaryStream(0, new ByteArrayInputStream(content), content.length);
            pstmt.close();
            conn.close();
        } catch (Exception ex) {
            ex.printStackTrace();
        }or instead of using ByteArrayInputStream try pstmt.setBinaryStream(0, new FileInputStream(yourFile), getFileSize());Hope this will help...

Upload text file to oracle table with checking and aggregation

Hi Friends,
I am new to ODI. I have encountered a problem which is specific to ODI 11G (11.1.1.6.3) to upload text file to oracle table with checking and aggregation. Would you please teach me how to implement the following requirement in ODI 11G?
Input text file a:
staffCode, staffCat, status, data
input text file b:
staffCodeStart, staffCodeEnd, staffCat
temp output oracle table c:
staffCat, data
output oracle table d:
staffCat, data
order:
a.staffCode, a.staffCat, a.status
filter:
a.status = ‘active’
join:
a left outerjoin b on a.staffCode between b.staffCodeStart and b.staffCodeEnd
insert temp table c:
c.staffCat = if b.staffCat is not null then b.staffCat else a.staffCat
c.data = a.data
insert table d:
if c.staffCat between 99 and 1000 then d.staffCat = c.staffCat, d.data = sum(c.data)
else d.staffCat = c.staffCat, d.data = LAST(c.data)
Any help on fixing this is highly appreciated. Thanks!!
Thanks,
Chris

Dear Santy,
Many thanks for your prompt reply. May I have more information about the LAST or SUM step?
I was successful to create and run the following interfaces p and q
1. Drag text file a to a newly created interface panel p
2. Filter text file a : a.status = ‘active’
3. Lookup text file a to text file b : a.staffCode between b.staffCodeStart and b.staffCodeEnd
4. Drag oracle temp table c to interface panel p
5. Set c.staffCat : CASE WHEN b.staffCat IS NULL THEN a.staffCat ELSE b.staffCat END
6. Set c.data : a.data
7. Drag oracle temp table c to a newly created interface panel q
8. Drag oracle table d to interface panel q
9. Set UK to d.staffCat
10. Set Distinct Rows to table d
11. Set d.staffCat = c.staffCat
12. Set d.data = SUM(c.data)
However, the interface q should be more than that:
If c.staffCat is between 99 and 1000, then d.data = the last record c.data; else d.data = sum(c.data)
Would you please teach me how to do the LAST or SUM steps? Moreover, can interface p and interface q be combined to one interface and do not use the temp table c? Millions thanks!

Chris

How to install Oracle 10g with its grid functionality on Linux?

Well, I thought changing the subject line might help to convey the meaning of what I want better. Here's my earlier post from a few hours earlier.
Hi,
I need carry out TPC-C benchmarking test for Oracle 10g (using one, two and four servers; basically using the grid in case of multiple servers). I have installed oracle 10g (with default options) on all the four servers, but beyond that I have no idea as to how can I invoke the grid option in order to carry out the tests-by my statement, I mean do I need to choose grid option while installing Oracle or is it the case that I specify the grid option in the code that I write for carrying out the tests. The OS is LInux (Scientific Linux).
An unrelated problem-one of the servers is 64 bit while others are 32 bit, and proper versions of oracle have been installed. Neglecting the obvious fact that this will make comparisons difficult does anyone anticipate any other problem?
Many Thanks!
Steve
*******************************************************************************************************

Do you think that the installation of RAC can be done
in a week? yes, as long as you know what you are doing and can catch the concept quickly and good at following instructions.
Moreover, we do not have a cluster-all we
have are four servers that are separate. Do you know
if the name Real Application Clusters implies that
the servers have to be in a cluster?
The basic idea of RAC is all these hosts need to share same set of storage. The most popular such storage are SAN and NAS.

Best practice for integrating oracle atg with external web service

Hi All
What is the best practice for integrating oracle atg with external web service? Is it using integration repository or calling the web service directly from the java class using a WS client?
With Thanks & Regards
Abhishek

Using Integration Repository might cause performance overhead based on the operation you are doing, I have never used Integration Repository for 3rd Party integration therefore I am not able to make any comment on this.
Calling directly as a Java Client is an easy approach and you can use ATG component framework to support that by making the endpoint, security credentials etc as configurable properties.
Cheers

Error when connecting an oracle DB with Integration gateway

I followed the steps from the blog How to connect an Oracle DB with Integration Gateway in SMP3 and the ojdbc was deployed successfully to SMP. Still, i'm getting "Driver class oracle.jdbc.driver.OracleDriver not found" error message when i try to test my connection. The first difference i saw when completing these steps was that I'm using SMP3 SP05, could this be the issue?

Joao D Franco Net
Could you share below information:
Can you cross check if deployed driver are OSGi enabled? Refer this.
Can you share screenshot of the destination settings and error ?
note: The blog you followed is referring to SP03 (1st GA of SMP3)..You should not have any problem in connecting to Oracle DB being on any SP.

JK
