Hello,
so for upgrading i should install oracle 11g? Yes you have to install Oracle 11.2 first. You may have to modify the configuration of the Server according to the prerequisites.
You'll find all the details on the Installation Guides for your platform:
http://www.oracle.com/pls/db112/portal.portal_db?selected=11&frame=
how it is possible without using import/export/datapump utilities?If you don't want to use Export/Import, you may use DBUA (the Database Upgrade Assistant) or Manual method. You'll have more informations on the links below:
http://download.oracle.com/docs/cd/E11882_01/server.112/e17222/preup.htm#i694345

Hope this help.

Porting from Oracle 10g AS to Oracle 11g Weblogic server

Hi,
I am trying to port J2EE applicatin from Oracle 10g AS to Oracle 11g Weblogic Server. I have jsp files which contains sql code embedded to fetch data from the DB. The components used in this application are Java, JSP, Servlets and Stateless session beans.
I have a commonjar which is used to create DB Connection manager and other common stuff which is present inside web-inf/lib. My application is packaged as an ear and which contains the war and different ejb-project.jar files. When the Stateless bean is trying to call the ConnectionManager class, which is present inside the commonjar inside web-inf/lib, I get InvocationTargetException. When I debugged in Eclipse, I see that that inside ejb the reference ConnectionManager, the variable cannot be resolved. So I guess at runtime, ejb is not able to locate ConnectionManager Class.
I tried to copy this jar to APP-INF/lib and the same jar is present inside web-inf/lib as well. In that case what happens is the jsp fails with the exception ConnectionManager cannot be resolved.
How can I make the ejb work by keeping the commonjar inside web-inf/lib alone.
Any help or suggestions?
Thanks
Raj

The classloader hierarchy in WLS looks like this (arrows denote inheritance direction):
Java bootstrap classloader <- Java CLASSPATH classloader <- WLS $DOMAIN_HOME/lib classloader <- Application (e.g., EAR) classloader <- web app classloader <- single JSP classloader
The Connection Manager is loaded by the web app classloader while the EJBs are loaded by the application classloader so the EJBs have no visibility to the classes loaded by the child (web app) classloader.
The simplest fix might be to move the Connection Manager jar file to the EAR file's APP-INF/lib directory.
One word of caution though, you need to be using WebLogic Server's Data Sources and JDBC connection pooling to make sure that you correct transactional behavior if the application is doing any sort of JTA transaction (regardless of whether the JTA transactions are using XA or not...).
Hope this helps,
Robert

Problem when exporting and importing project from odi 10g to odi 11g

Hi,
I want to migrate my project from odi 10g to odi 11g.
But when i am importing the interface then it is giving the error of mising references .
I have exported the project(without its child component),models
(including my datastore),KM's,folder (without its child component),packages(with child components),interaces(with child components),procedures(with child components),variables from odi 10g.
After exporting all these objects i imported all the objects with import type set as "Synonym mode insert" into odi 11g but when i imported the interface it is giving the error of missing references.
Source technolgy is Oracle and target technolgy is Postgres.
Topologies have been made in the ODI 11g same as in ODI 10g.
Please help.

You dont need to migrate the complete repository. You can migrate a project at a time into ODI 11.1.1.5.x
You have to be careful while importing. You have to follow a sequence when importing.
Empty Project -> KMs -> Models (with DB Stores) -> Variable -> Empty Folders -> Interfaces -> Procedures -> Packages ---- All in SYNONYM mode insert (no exceptions)
And your repository id in 11g MUST be different from the one in 10g.

Retrieve data from a large table from ORACLE 10g

I am working with a Microsoft Visual Studio Project that requires to retrieve data from a large table from Oracle 10g database and export the data into the hard drive.
The problem here is that I am not able to connect to the database directly because of license issue but I can use a third party API to retrieve data from the database. This API has sufficient previllege/license permission on to the database to perform retrieval of data. So, I am not able to use DTS/SSIS or other tool to import data from the database directly connecting to it.
Here my approach is...first retrieve the data using the API into a .net DataTable and then dump the records from it into the hard drive in a specific format (might be in Excel file/ another SQL server database).
When I try to retrieve the data from a large table having over 13 lacs records (3-4 GB) in a data table using the visual studio project, I get an Out of memory exception.
But is there any better way to retrieve the records chunk by chunk and do the export without loosing the state of the data in the table?
Any help on this problem will be highly appriciated.
Thanks in advance...

Girish...Thanks for your reply...But I am sorry for the confusions. Let me explain that...
1."export the data into another media into the hard drive."
What does it mean by this line i.e. another media into hard drive???
ANS: Sorry...I just want to write the data in a file or in a table in SQL server database.
2."I am not able to connect to the database directly because of license issue"
huh?? I never heard this question that a user is not able to connect the db because of license. What error / message you are getting?
ANS: My company uses a 3rd party application that uses ORACLE 10g. And my compnay is licensed to use the 3rd party application (APP+Database is a package) and did not purchased ORACLE license to use directly. So I will not connect to the database directly.
3.I am not sure which API is you are talking about, but i am running an application of the visual studio data grid or similar kind of controls; in which i can select (select query) as many rows as i needed; no issue.
ANS: This API is provided by the 3rd party application vendor. I can pass a query to it and it returns a datatable.
4."better way to retrieve the records chunk by chunk and do the export without loosing the state of the data in the table?"
ANS: As I get a system error (out of memory) when I select all rows in a datatable at a time, I wanted to retrieve the data in multiple phases.
E.g: 1 to 20,000 records in 1st phase
20,001 to 40,000 records in 2nd phase
40,001 to ...... records in 3nd phase
and so on...
Please let me know if this does not clarify your confusions... :)
Thanks...

If this does not work, then Oracle HSO will also not work.
Once you have confirmed that this is working, then configure the HSO service for Oracle.
If that fails, enables ODBC client tracing for that HSO service (in the init file for that service) to see exactly what ODBC calls Oracle is making and which of these are failing.

Replication of table from Oracle 10g to sql server 2000

Could i replicate table from Oracle 10g to sql server online. we have tables with same configuration and if any change happen in oracle 10g or sql server in that table we need to replicate that change to other database.
What is the solution for this two way replication between sql server and Oracle 10g

But the tutorial is saying that i will have to install Oracle database on the server already having sql server, is it client or whole database, if it is then it will acquire lot of resource.
I want to find out that for Heterogenous Service ODBC, we need third party software for ODBC Driver of SQL SERVER for Linux and secondly if we use Transparent Gateway then what are the steps for its configuration.
I could not find steps of configuration of Transoparent gateway, when i am trying to install Transparent gateway from Universal installer, it is not there. where do i find it , Do i need to purchase it too.

Retrieval of xmltype data from oracle 10g to java

Hi
Right now we are facing an issue on xmltype retrieval from oracle 10g to java.
I used xmltype column.getClobval() to get the xml content, but unable to do the parse to get the xml data.
So i tried getStringval(), getting the xml content as string format and here in this case also, i didn't get document object.
Here is the code snippet:
String sql = "SELECT node_id,node_desc,parent_node_id,e.report_xml.getStringval() FROM TABLE_STRUCTURE e";
st = con.createStatement();
rs = st.executeQuery(sql);
while (rs.next()) {
Object value[] = { rs.getString(1), rs.getString(2), rs.getString(3), rs.getString(4) };
list.add(value);
DOMParser parser = new DOMParser();
parser.parse(rs.getString(4));
doc = (Document) parser.getDocument();
System.out.println(": DOM = " + doc.getClass().getName());
Please do guide in this scenario.
Thanks in advance.

Upgrading from Oracle 10G standard edition to Oracle 10G enterprise edition

Hi
I want to upgrade from Oracle 10G standard edition to Oracle 10G enterprise edition. Is there any script provided by oracle which I can run on existing Oracle 10G standard edition to upgrade to enterprise edition after completing the licensing formalities or do I need to install Oracle 10g Enterprise edition from scratch and then migrate my data.
Ramanbir S

You will not need to perform any data migration to upgrade to EE. The diffetence between standard en enerprise editions are the features offered. When you upgrade you can use the same set of files you used to install standard edition and just add the enterprise edition features you want to use in the 'Custom' section of the Universal Installer.

How to migrate a table from ORACLE 10g to 8i

have table named 'liuxg_tab_01' in 10g.
This morning I exported this table using 'exp' and then tried to imp it into 8i, I failed.
After a while, I created a database link named 'ctf' in 8i which connected to 10g. I issued 'create table test as selct * from liuxg_tab_01@ctf',it returns 'ORA-01723'.
Then I extraced the DDL of 'liuxg_tab_01' from 10g with QUEST TAOD, it's:
CREATE TABLE LIUXG_TAB_01
OWNER VARCHAR2(30 BYTE),
OBJECT_NAME VARCHAR2(30 BYTE),
SUBOBJECT_NAME VARCHAR2(30 BYTE),
OBJECT_ID NUMBER,
DATA_OBJECT_ID NUMBER,
OBJECT_TYPE VARCHAR2(19 BYTE),
CREATED DATE,
LAST_DDL_TIME DATE,
TIMESTAMP VARCHAR2(19 BYTE),
STATUS VARCHAR2(7 BYTE),
TEMPORARY VARCHAR2(1 BYTE),
GENERATED VARCHAR2(1 BYTE),
SECONDARY VARCHAR2(1 BYTE)
But I can not create a table using the upper DDL in 8i if I do not wipe off those "BYTES".
After creation of the table using the upper DDL without those 'BYTES', I sucessfully executed 'insert into LIUXG_TAB_01 select * from liuxg_tab_01@ctf'.
Anyone has a better method to move a table from ORACLE 10g to 8i?

1) The particular version of 8i and 10g in use here would be useful. I'm not sure that Oracle supports database links between any version of 8i and any version of 10g, though, so you're probably lucky that it worked as well as it did.
10g 10.1.0.3.0 and 8i 8.1.7.0.0
2) What version of the export utility did you use? You would need to use the 8i version to generate the dump file to have any chance of working, not the 10g verion.
I use the 'exp' provided with 10g 10.1.0.3.0 and 'imp' with 8i 8.1.7.0.0. I have tried to export data directly from 10g 10.1.0.3.0 using 'exp' provided with 8i 8.1.7.0.0. Failed.
3) Why? Since 8i is desupported, there isn't a lot of call for tools to move data from supported releases to unsupported releases.
We have an 8i DB which is still porivding insentive services. We just wanna migrate some tales from 10g to it.
FYI, NLS_LENGTH_SEMANTICS was introduced in 9i, so it's no suprise that 8i objected to the BYTE keyword in the DDL.
What's FYI :P
Another option would be to generate a CSV file of the data from 10g and use SQL*Loader to load it into 8i. Not sure this would be any easier, though.

GetBlob Error During fetching of Images from Oracle 10g

Dear Sir,
By using getBlob Function ,i am getting following error:"Unsupportable action has performed".
I am using oracle 10g.I am using java code to retrieve image from Oracle 10g.
So plz help me by giving full code with explaination.
Thankyou.
Yours Obedient
Dipesh Kumar

I seriously doubt Oracle would write error messages with such atrocious English.
So it's almost certainly an error from either your own code or code you're calling in some library or part of the application you're not mentioning that noone here except you has knowledge of.
Ergo, we're not going to be able to help you unless you provide a lot more information.
And no, we're not going to write your code for you.
