Links needed for portal devlopment on oracle 10g appserver using jdeveloper

hi,
i'm relatively new to portals so wud like to hav sum knowledge of doing basing request & response stuff using jsp's as my UI while developing portlets using Jdeveloper.
If anyone could come up with tutorials about portal development on Jdeveloper.
i'm using oracle 10g AS app server(release 10.1.4) with oracle jdeveloper( version 10.1.2.0.0 build 1811).
wud like inputs on wsrp & jsr-168 compliant portlets

Hi,
You could try starting with the Portal Developers Guide - http://download-west.oracle.com/docs/cd/B14099_19/portal.1014/b14135/toc.htm
You should also find alot of useful info on the Portal Development page on OTN - http://www.oracle.com/technology/products/ias/portal/portlet_development_10g1014.html

Thanks..

Is your problem that you do not know how to send an email from Oracle 10g? If so then you use the UTL_MAIL package.
Here's an example of calling it as part of a scheduler chain, not strictly what you're asking for but this lets you define success and failure steps and call each one based on the status of previous steps.
BEGIN
DBMS_SCHEDULER.CREATE_PROGRAM (
   program_name           =>'prg_Export_Success',
   program_type           =>'PLSQL_BLOCK',
   program_action         =>q'[BEGIN
                                UTL_MAIL.SEND (

                                   recipients => '[email protected]',

BLOB insertion in Oracle 10g database using ojdbc14 (10g drivers)

Hello!
I have a situation where I am trying to insert a blob data into oracle 10g database using oracle thin
10g drivers, ojdbc14.jar in weblogic 8.1 sp2. I have the following error happening very intermittently.
java.sql.SQLException: OALL8 is in an inconsistent state.
And this is leading to the "No more data to read from socket" error when I am trying to
insert the BLOB into the database. I have gone through the bug list of SP2 and have realised there is the
following issue fixed in SP3.
CR124933
An Oracle BLOB sometimes used a pooled connection after the connection pool determined that
the connection was available for reassignment.
Code was added to ensure the BLOB is completely processed before closing the pool connection or
ending the transaction.
I believe the problem arises when we try to insert BLOB into database using a refreshed connection
from the pool.We have upgraded weblogic 8.1 from SP2 to SP4 service pack inorder to come over the above problem.
But this still continues to behave intermittently.
We put ojdbc14.jar in our classpath and Weblogic startup classpath looks like the following :-
WLS_CLASSPATH=${WLS_DOMAIN_DIR}/appslib/server.jar:$PRE_CLASSPATH:${WLS_WEBLOGIC_HOME}/server/lib/weblogic.jar:
${WLS_WEBLOGIC_HOME}/server/lib/ojdbc14.jar:${WLS_WEBLOGIC_HOME}/server/lib:${WLS_JAVA_HOME}/lib/tools.jar:
${WLS_JAVA_HOME}/jre/lib/rt.jar:${WLS_WEBLOGIC_HOME}/server/lib/webservices.jar:${WLS_CONFIG_DIR}:
${WLS_CUSTLIB_DIR}:${WLS_BIN_DIR}:$POST_CLASSPATH
export WLS_CLASSPATH
CLASSPATH=${WLS_CLASSPATH}:${APP_CLASSPATH}
export CLASSPATH
After upgrade to SP4, there are new ojdbc14_g.jar(debug jar) and orai18n.jar jars in the ${WLS_WEBLOGIC_HOME}/server/ext/jdbc/oracle/10g directory added.
Please let me know if I need to update classpath with the new 10g jars in the ext/lib directory or any suggestions
to insert BLOB using the ojdbc14 10G drivers, Weblogic 8.1 environment would be appreciated.
Following is the stack trace of the errors that I recieve:
<Oct 6, 2005 1:29:36 PM EDT> <Error> <JDBC> <BEA-001112> <Test "select count(*) from DUAL" set up for pool

getting using and closing pool connections? The initial symptom
seems to be an internal oracle problem... Are you using standard
JDBC or oracle-specific calls?

Emmedding Oracle 10g XE into JDeveloper

Recently competing IDE suppliers are embedding databases out-of-the-box to their IDE's. SJSC2 has Pointbase and Netbeans will have Apache Derby.
I think for JDeveloper this would add value so we can (without installing Oracle separately) use a database directly.
Would it be an idea to embed Oracle 10g XE to JDeveloper?

Shay,
The discussion as it's going now is just what I wanted. I think there was some good feedback.
I think until now there is a 50-50 tie for embedding it and keeping it separate.
I'm a little bit surprised because for 'real' JDeveloper users, an embedded database is not really needed as working in projects means that there is central installed database. And I expected thoses users around on this forum.
Personally speaking, when working with JDeveloper on projects an embedded database is not needed. As I said before, most of the times in this case there is a central database server hosting the database.
So for those people I understand they prefer keeping it separately (to keep it small).
But there are cases that it really would add value:
- JDeveloper Starters: starters who want to experience with JDeveloper and e.g. do some ADF tutorials need to install Oracle. Because of this additional installation many of them will bail out; that's not what we want!
- Students: I JDeveloper would have an embedded database it could be used more easily for education on schools; the younger they start, the better!
- Regurlaly/Experienced JDvelopers users who want to try something at home but don't have Oracle installed for some reason.
For me it doesn't have to be Oracle XE, because it's still fairly big. It could also be a embedded Java database like Derby or HSQL. As long as it works with ADF Business Components without problem. (I tried MySQL once, but it didn't worked optimal with BC4J: e.g. primary keys are not added)
Also remember that JDeveloper is shipped with embedded OC4J out-of-the-box. I know you cannot compare this to an embedded database, but it is in and you can choose to use it or not.
Regards,
Marcel

How to configure Oracle 10g to use 4GB memory

I'm trying to configure Oracle 10g to use >4GB memory. Have configured server boot.ini with required flags (/3GB /PAE). Rebooted server then created standard database, then connected to db instance and changed oracle parameters DB_BLOCK_BUFFERS, USE_INDIRECT_DATA_BUFFERS as required. Restarted DB instance, DB fails to restarted with SGA memory error. According to oracle user docs the SGA is nolonger in effect due to previous settings. Can you provide example of SPFILE with parameters settings that do work and use >4GB memory. Current server has 8GB, 2 x Dual XEON core/processors (i.e. 8 processors)

The recommended /3GB switches in the boot.ini file can only be used with the following operating systems editions (KB article 291988):
Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Data Center Server
Microsoft Windows Server 2003, Enterprise Edition
Microsoft Windows Server 2003, Data Center Edition
Microsoft Windows Small Business Server 2003
Important: Windows 2000 and 2003 Server Standard Editions DO NOT SUPPORT /3GB Switch.
So if your OS is listed above, then you cannot have a larger SGA.

Converton of oracle 9i forms using JDeveloper

Can we convert an oracle 9i forms using jdeveloper?

The links point to my blog and product (OraFormsFaces). The poster is right that OraFormsFaces is a licensed product.
It is a library consisting of a number of components:
* extensions to Oracle Forms adding a JavaScript API to Oracle Forms
* a number of JSF component allowing you to embed an Oracle Form in a JSF page, and pass parameters and raise events from Forms to JSF and in the other direction
* extensions to the Forms applet allowing for a single Forms applet to be reused during your entire web session. Normally each web page embedding Oracle Forms would start a new applet, which is prevented by OraFormsFaces using a single applet for the entire session
* optional visual integration of Oracle Forms in the JSF page that can blend the form into the page, removing the title bar, menu bar, tool bar, status bar, and other chrome
* supporting PLL libraries to bring the OraFormsFaces functions to Forms PL/SQL
To get an overview of the product and some viewlets demonstrating JSF/Forms integration, please visit http://www.commit-consulting.com/oraformsfaces/
I personally feel that OraFormsFaces could be the missing link for Oracle Forms users wanting to go forward. Many Forms users want to use JSF or other web technologies for new developments but they don't want to be forced into a time consuming and expensive rebuild of their Forms application in web technology. OraFormsFaces allows you to create hybrid systems consisting of new JSF pages and existing Oracle Forms while both can pass parameters and events to the other. This gives the end user and integrated application without a need for development to do a major rebuild/rearchitect.

How To Execute an Oracle 10g SProc using VS 2005, for Reporting Services

Good day! :-)
Anybody who knows the syntax for executing an Oracle Stored Proc thru ODBC connection using VS 2005 for Reporting Services? I am having a problem about this.
I am using the ODBC connection because VS 2005 does not support Oracle Database 10g in its Oracle Database Connection feature (only 7.3, 8i, and 9i), that's y.
While using MS SQL Server 2000, I never encountered any problem. But using Oracle Database 10g, I find it hard to call the stored procedures, an error is generated everytime.
Please click the link below for the screenshots:
http://www.geocities.com/vrcode2/oraError.JPG
http://www.geocities.com/vrcode2/storedProc.JPG
Please help...thank you so much.
Francis

I'll give you updates about the use of the MS SQL Server Reporting Services with VS 2005 and Oracle, this might be helpful for those who will encounter this same ctuation in the future.
I have discovered that if you're going to connect thru ODBC, even if the connection is successful, the user is still prompted to input a password, which should not be the case when using the Reporting Services. Another thing to take note is the issue about REF CURSOR, we're going to have problems with this. And also the syntax on how you're going to call the stored procedures (with or without input parameters).
With modifications made through Oracle Net Manager, and I tried AGAIN connecting through "Oracle (client)" feature of VS 2005 (even if the list only include Oracle 7.3, 8i, and 9i that are supported) with some changes also, you'd still be able to generate correct data with that solution. If the configuration is correct, you just need to call the stored procedure (with or without input parameter), you won't have any problems about the correct syntax.
I suppose VS 2005 was released earlier than Oracle 10g, that's why 10g wasn't included If ever u'd encounter the same ctuation like mine, and u need the details on how to connect, do not hesitate to ask me.

Required setting for Locale values for Arabic db in oracle 10g

I want to create a new db in Oracle 10g for storing the arabic data.
My client machine is Arabic Windows XP.
What are the steps that i will need to follow to make the db arabic supported.
What streps will be required if i choose to make it unicode supported?
Setting the following:-
1. Set Database Character Set to AL32UTF8 for the Oracle Server.
2. Set the NLS_LANG to ARABIC_LIBYA.UTF8 (on Arabic Windows xp)
Will do the work?

The database character set should be AL32UTF8 for Unicode support. This is a recommended setting.
As far as NLS_LANG is concerned, this strongly depends on how your client application is written (what technology, which Oracle access API). For example, for SQL*Plus, the NLS_LANG must be set to AR8MSWIN1256, as SQL*Plus does not support Unicode on Windows, only the ANSI code page. For SQL Developer, the NLS_LANG does not matter at all.

Problem while inserting data for some datatypes in Oracle 10g

Hi
I was trying to insert data in database for all the data types defined in Oracle 10g.
I was successful in maximum cases.
I was not able to insert data for following datatypes:
1 Long varraw
2 string
3 varraw
4 varnum
5 charz
6 unsigned int
7 native double
8 native float
Please put some light on it.
Thanks,
Gyanendra

Hi Subin,
You can try couple of things.
If your data is less than 32767, you can pass it to stored procedure and change it to clob type like
PROCEDURE CLOBQUERY
Param IN CLOB,
and you can call Procedure
EXECUTE CLOBQUERY '[Param.1]'
If your data is around than 1000000(32767*32), you can break the data in length of 32767 and pass it to param 1 to 32 like
EXECUTE CLOBQUERY '[Param.1][Param.2][Param.3]..[Param.32]'
Finally you can try to update jdbc drive.

Need SQL tuning tips in oracle 10g.

From time to time I come across some slow running queries used in SQR. I want to know the tuning technics in oracle 10g as I believe it is different now becasue of CBO.
As I am not an oracle man to tune the query I can try if there are any guidelines. Also while optimizing a query what are the important things need to be considered:
Do you want the first rows back quickly (typically during online processing) or is the total time for the query (typically a batch process) more important?
Are the tables properly indexed to take advantage of the various operations available?
How large are the tables? Joining smaller tables first is usually more efficient.
How selective are the indexes? Indexes on fields that have only a few values don't really help.
How is sorting done? Are sorting and grouping operations necessary?
Any help is greatly appreciated.

How large are the tables? Joining smaller tables first is usually more efficient. The optimizer usually makes this decision
How selective are the indexes? Indexes on fields that have only a few values don't really help. But can still be useful if the data can be read from the index instead of the table.
How is sorting done? Are sorting and grouping operations necessary? This is a business requirement, if you need to sort you need to sort.

Broken image links on APEX 3.0 in Oracle 10g XE? Here's the solution

You're on Oracle 10g XE and you've just upgraded your APEX from 2.0 to 3.0. You log into APEX Admin and there's tons of broken image links. You look into the Oracle documentation for APEX and it instructs you to copy the Images folder into your htmldb directory if you're using Oracle 10g standard, etc. But you're using Oracle 10g XE and there is no Images folder anywhere to be seen!
HERE'S THE SOLUTION:
http://daust.blogspot.com/2006/03/where-are-images-of-application.html
Excerpt from the website:
In OracleXE these resources (Images) are stored directly in the database, using the Oracle XMLDB feature. You can access the resources and modify them directly by using the WebDAV feature of the XMLDB.
(1) With Internet Explorer, just go to File > Open > http://127.0.0.1:8080/i (check "open as webfolder")
Then, copy the contents of your apex/images folder into this webfolder. It will take about 10 minutes. When it's done, refresh your Apex 3.0 website and lo and behold! Images! :)
Be sure to thank Dietmar Aust for his solution to this problem, provided on his website: http://daust.blogspot.com/2006/03/where-are-images-of-application.html

Another option: Try the Oracle Database XE and Application Express 3.0.1 install guide.
