Synch JDBC Receiver - stored procedure

Hi All ,
Can you please let me know whether we can go for a Synch JDBC receiver which needs to excute a stored procedure at the target DB system ? If Yes , Please let me know the procedure .
Thank you.

Inserting and retrieving data from a al32UTF8 database USING SQL Developer

hi guys,
Before i post my questions , i think its better for me to provide you guys with my understandings first so that it easier to understand where/if i have gone wrong..
I am using Window XP and Oracle 10g
Non-unicode client - a client program that need to use the OS code page for mapping of the retrieved unicode data from the database as well as the support of displaying/inserting the characters from that code page to the database.
E.G sqlplusw.exe
Therefore, when using a non-unicode client
1) we have to set the OS code page (Control panel - regional and language setting - advance - language for non unicode program ) to the code page that contain the characters we are going to display/insert.
2) we will also have to set the NLS_LANG characterset to the character set of the code page we are going to insert so that when we do a insert (for e.g in thai ) , oracle will know, and auto conversion to UNICODE can take place. This is also true when we retrieve unicode data from the database so that conversion to the correct character set can take place.
INSERTING
THAI ---> conversion ----> UNICODE
RETRIEVING
THAI <---- conversion <---- UNICODE
I hope my basic understanding is correct up till this point.
Unicode client - a client program that supports the displaying/inserting of unicode characters without the need of setting the OS code page (Control panel - regional and language setting - advance - language for non unicode program )
E.G isqlplus http or SQL developer
However,
1) There is still a need to set the NLS_LANG so that correct conversion can take place between the client and the database.
For e.g, when retrieving if we set the NLS_LANG character set to ZHS16GBK (chinese) and the data store in unicode in database is E.G (THAI) , then the conversion would be wrong .
Since it is a unicode supported client, then the NLS_LANG character set should be set to UNICODE as well.
Here come my questions
*Important - please help if you are busy and have no other time to answer the rest of the questions
*Q1) If i were to use a unicode client, what should i set my NLS_LANG character set to ?
AMERICAN_AMERICA.UTF8 ?
*Q2) Where do i set the NLS_LANG character set information in SQL Developer, i know there is a metalink for setting NLS_LANG using isqlplus but i cant seems to google any result for SQL developer.
Q3) Is my basic understanding right until this point ? If not, please explain in a more generalised term as i am really not familiar with character sets, code page, unicode , glyphs and fonts..
Q4) If a unicode client does not need to refer to the OS code page (set in regional and language) , is there a UNICODE code page for the client to refer to , or is there any Window API available ?
Q5)
There is still a need to set the NLS_LANG so that correct conversion can take place between the client and the >>database.
For e.g, when retrieving if we set the NLS_LANG character set to ZHS16GBK (chinese) and the data store in >>unicode in database is E.G (THAI) , then the conversion would be wrong .am i right on this point for UNICODE supported client ?
Thanks for spending time to read my questions and i hope to hear advices from you guys soon.
Million thanks again for sharing.
Best Regards,
Noob but willing to learn

The requirement to always set NLS_LANG is not true for JDBC, which ignores NLS_LANG altogether. Java programs fetch text data into String variables, which use Unicode UTF-16 by design. JDBC sets character set conversion so that data is converted between UTF-16 and the database or national character set.
The requirement to set NLS_LANG is not generally true for OCI, either. The first call in an OCI problem can be OCIEnvNlsCreate(). This call has two parameters that allow the caller to define the character set to use for VARCHAR2/CHAR/LONG/CLOB/statement text and the character set to use for NVARCHAR2/NCHAR/NCLOB. Only if these character sets are specified as 0, NLS_LANG character set is used. Also, OCI programs can specify different character sets for each bind or define variable (i.e. input/output buffer). Note: OCI programs always use NLS_LANG to initialize the language and territory settings for the client program and the database session. Only the character set can be specified is OCIEnvNlsCreate().
OCIEnvNlsCreate() can specify the client character set as UTF-16 (in platform endianess). This is not possible with NLS_LANG.
Various interfaces building on OCI, such as Oracle ODBC and ODP .NET, explicitly initialize OCI with Unicode character set, and thus ignore the NLS_LANG character set as well.
Thnx,

Migration from OAS 10g to Weblogic 10.3

Hello,
I migrate large app from OAS 10g to Weblogic 10.3.
1.
The main part of the job was to prepare descriptors for Weblogic. Unfortunatelly I don't find any tool that could do the job:( There are some problems with descriptors namespaces. This schema and namespaces given in 10.3 docs are not working (not available):
http://edocs.bea.com/wls/docs103/ejb/DD_defs_reference.html
So I use the one from 10 release in weblogic-ejb-jar.xml:
weblogic-ejb-jar xmlns="http://www.bea.com/ns/weblogic/10.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/10.0 http://www.bea.com/ns/weblogic/10.0/weblogic-ejb-jar.xsd">
and form 9 release in weblogic-cmp-rdbms-jar.xml:
<weblogic-rdbms-jar xmlns="http://www.bea.com/ns/weblogic/90" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-rdbms20-persistence.xsd">
There are also some bugs in docs about ejb relations.
After fixing some schema compliance exc this step success.
2. Next the EJBComplianceChecker - its much more restrictive than OAS verification. So updates in ejb interfaces are necessary. It is not a problem with small app but when there ale a lot of code/branches to migrate it's become a problem. I have been looking for some switch that could help with this but with no result/
EJBComplianceChecker - Spec veryfication level
3. Now after EJB compliance checker done its job with success I have an exception that I do not understand:
An error occurred during activation of changes, please see the log for details.
Exception
preparing module: EJBModule(corpo_ejb.jar)
Unable to deploy EJB: corpo_ejb.jar from corpo_ejb.jar:
There are 1 nested errors:

Could you please give me some point where the problem could be? I don't have any idea where to start looking for..
What are your experiences with migrations from OAS to Weblogic 10?

Hi Stoigniew Sztank,
I am working on migrating Enterpirse application developed using Struts, Ejb2.0, JMS. Its been deployed on OAS 10G and Websphere, but I need to deploy the application on Weblogic 10.3. It seems you have migrated a J2ee application from OAS 10G to Weblogic 10.3. Please can you list me the steps that you followed to migrate the application.
As per my understanding follwing things needsto be taken care of:-
1) Weblogic Descriptor files:
1.1 Weblogic.xml:- we added security roles and ejb-reference-description for the ejbs.
1.2 Weblogic-ejb-jar.xml for all the ejbs used in the application.
1.3 Weblogic-application.xml
1.4 Resource Adapter
2) JMS queue set up
3) JDBC set up
It would be a great help if you can let me know what are the steps to migrate the application.
Thanks and Regards

EUS password authentication in sql developer failing with username/password

We have recently changed to use Enterprise User Security (EUS) for our client authentication (password global authentication).
This is working fine but we are encountering an issue with SQL Developer whereby we can't logon using our EUS details, it simply returns the following on the logon screen:
Status : Failure - Test failed: ORA-01017: invalid username/password; logon denied
Logging on via sql plus client and server software and other 3rd party tools like pl/sql developer works correctly.
It appears to be an issue with sql developer itself.
We are using the latest Production release of sql developer 2.1
Does anyone have any ideas?
This is an issue for
Edited by: david butler on Jan 14, 2010 10:45 AM

Further to this, I have now found a suitable resolution to this that doesn't require an external client.
There is a jdbc setting that will allow you to use EUS password authentication.
Add the jdbc line option (below) in the sqldeveloper.conf file (backup the sqldeveloper.conf file first).
AddVMOption -Doracle.jdbc.thinLogonCapability=o3
The sqldeveloper.conf file can be found wherever you have installed sqldeveloper, under <INSTALL_HOME>\sqldeveloper\bin\sqldeveloper.conf.
After you add this option, restart SQL Developer and you should be able to use your EUS username / password to authenticate via SQL Developer.

Making LOV off of an exposed method from second application module

Hello,
I am on JDev 11.1.1.4.0.
My ADF project worked fine until the spec changed on how Lookups are going to be handled. Previuosly, all the lookup tables were in the same database as other tables. Change is that FND Lookups will be created in the "Oracle" and my ADF project should connect to "Oracle" to get appropriate lookup values to build LOVs while maintaining the main database connection intact.
After some research, I now have 2 Application Modules, one my project and the other for Lookups to create LOVs. I went to Application Module configuration wizard to edit JDBC setting to point to "Oracle" database and created a read only view with the following SQL:
SELECT LOOKUP_CODE, MEANING, DESCRIPTION FROM FND_LOOKUP_VALUES
WHERE LOOKUP_TYPE = 'MY_LOOKUP'
AND ENABLED_FLAG = 'Y'
AND LANGUAGE = 'US'I can run both AMs via "Oracle Business Component Browser" fine. However, I somehow have to set the lookup view object as data source to create LOV on the main updatable view object's attribute. If I set it the way I used to do treating the lookup view as a view object residing in the same AM I am getting "table or view does not exist" error. I guess it is something to do with the lookup view object, but I cannot seem to make any kind of progress on this.
Any help would be greatly appreciated.
Thank you
Bones Jones

Well, I think I have found a solution which I didn't have to write a single line of code. My mistake was to think that I have to write code to achieve this.
Here is what I did:
*I already have the main AM and View Objects created for my project. The following steps are done on top of that to bring LOV to life
1. Create a new, pretty empty AM, named LovAM.
1.1 Right click on the newly created AM and select 'Configurations'
1.2 Click JDBC Name value and click 'Edit'
1.3 Select the second database source where Lookup is defined. If not listed, go back out and create a new Database connection and come back.
2. Create a View Object with the following SQL:
SELECT
    TO_NUMBER(LOOKUP_CODE) ID,
    MEANING NAME,
    DESCRIPTION
FROM
    FND_LOOKUP_VALUES
WHERE
    LOOKUP_TYPE = 'MY_LOOKUP' AND ENABLED_FLAG = 'Y' AND LANGUAGE = 'US'3. Notice you now have LovAMDataControl
4. Create a jspx page and create a table with the main data control's binding (This was a part of the requirements).
5. I create a read-only table with LovAMDataControl.LovLookUp1 binding (I think this creates/exposes correct binding in the pageDef).
6. Now I drag-and-drop an attribute that I have been wanting to display LOV from the main binding.
7. Selected single select listbox. You will be presented with 'Edit zlist Binding' screen.
8. Base Data Source is the main data control binding.
9. Select Dynamic List
10. Select LovAM data control binding as List Data Source.
11. (optional) Selected 'Name' as Display Attribute.
11.1. (optional) I don't want to see the table created in step 5. On the jspx page, go to Source tab and delete the table from there. I think this keeps binding in pageDef while the UI component is deleted from the page.
12. Save and Run
Now, I didn't have to create Root Application Module in the code, but still achieved what I wanted.
Thanks

Cannot access 'BookstoreServlet' in J2EE tutorial

ok so i've successfully created a jdbc-pool and a jdbc-resource...once i deploy the war file for the bookstore demo, i get:
HTTP Status 404 - Servlet BookStoreServlet is not available
type Status report
message Servlet BookStoreServlet is not available
description The requested resource (Servlet BookStoreServlet is not
available) is not available.
Apache Tomcat/5.0
i can perfectly access the 'hello1' example created earlier in the tutorial....i'm using jre 1.4.2 beta 2 with j2ee sdk 1.4 beta 2
ne help please? ...tks all

First, you can try the http://localhost:8080/bookstore1/banner.
If /banner cann't run, it should be the deploy problem.
If this can run, but /bookstore and other alias cann't run, the reason
should be the database connect issue.
To resolve database connect issue:
1. Get the database name:
go to $InstallDir\pointbase\tools\serveroption
run startserver.bat to start pointbase
run startconsole.bat to start database console, after you connect to databse,
you can see the jdbc:pointbase:sample on the menu. Here sample is the database name.
2. Verify JDBC setting in application server:
Application Server
--> JDBC
--> Connection Pool
--> PointBasePool
--> Properties
DatabaseName = jdbc:pointbase:server://localhost:9092/sample
(notice: here the sample must same as the database name in Item 1)
User=pbpublic
Password=pbpublic
3. Notice:
1) When run sample, first start pointbase database, then start application server
2) At the beginning, you can type "c" in pointbase service consle to see active connections link to database.
If after the application server started, if no active connections shown, this means your JDBC setting is wrong. You need to double check your setting.
3) Seems the pointbase only can accept 1 connect at the same time. So before run application server, you need to close the pointbase admin console.
I am also a beginner to J2EE.
Also looking forward for your kindly support!
Thanks in advance!

How can I speed up the connection to the database?

I am running a JSP application with regular JavaBeans not EJB and connecting to the database through these beans. The connection is set to stay in memory as long as the bean is in session. However when I am running more than 7 sql statements seperatly the execution of the page slows down.
I have tried using connection pooling but doesn't help much.
I am not using the JDBC setting in JRUN, I am connecting through the jdbc.odbc drivers provided by the JDK. Basically coded the connection and the connection pool.
Is there something else that can be done to speed up the execution of the page?
Thanks in advance

Thank you all for your input I was trying to work this project to learn JSP so I am not looking at purchasing any drivers right now. That is the reason why I stuck to the JDBC-ODBC Bridge. Are there any other drivers available for MS SQL Servers that are free.
Jschell,
That suggests you are taxing the system. It could be >connections. It could also be network, cpu, bus, etc. It >could also be memory, if your app starts swapping to >the hard drive it will get substantially slower.How can i figure out which of the above (i.e. memory, cpu, connections, network) are causing the problem.
(Presumably you explicitly close your >ResultSets/Statements/Connections when you are >done with them.)You are right about that yes I am closing them at the end of the session, which I think should be after all of the SQL's get executed but I could be wrong it might be openeing a new connection for each SQL which inturn might be the reason for this whole problem. I will take a look into that.
Thank you all once again.

Need Help - JBO-26000 Error on Tomcat?

I have been deploying my JDev 10.1.3 project (ADF BC) as a .war file to Tomcat 5.5.9 and running it successfully for several months successfully. Today while making code changes, I started to encounter a JBO-26000 error preventing me from running this application. I tried re-installing the ADF filters on Tomcat but this did not help.
Note! I have another project that I can still deploy and run successfully as a .war file in Tomcat, so it points to something specific to this application.
Does anyone have any suggestions? I don't know where to look for the problem?
Thanks.

Thanks John!
I just solved the problem 5mins ago :)
I'm using Jdeveloper 11g (11.1.1.2.36.55.36) and Tomcat6.
The point is that it had nothing to do with tomcat jdbc setting in context.xml or server.xml files.
After deploying your application to tomcat, bc4j.xcfg is the first place to look for errors regarding connection to database.(at least in my case)

JDev 11g Pr3 Not able to switch schema on database navigator

I have a schema called FACETSEDI that is used to access a schema named FACETS.
When I connect to the DB using the FACETSEDI login, I can run queries against the FACETS tables, but I can't browse them, since the navigator is pointing at the FACETSEDI schema.
Is there some custom JDBC URL I can use to cause the connection to force a switch on the session (simulate a ALTER SESSION SET current_schema = facets) ?

Absolutely:
1. Start JDeveloper
2. Go to the database navigator
3. Create a connection to the database
username: facetsedi
password: mypassword
driver: thin
hostname: facets
SID: facets1
4. Connect to the database
5. Expand the Tables node - and all I see are tables in the FACETSEDI schema
What I need is to be able to see the tables in the FACETS schema.
Can't find a way to specify this with a custom JDBC setting (like with SQL server I could specify a parameter in the URL to connect to the correct database schema).
There used to be a "show all schemas" setting on the IDE that let you pick which schema you wanted to see.

Problems in starting up Connection Pools in SQLServer7

Hi
We are running both Commerce and Personlaization Server 3.5 with an SQL erver
7 backend. I recently migrated the database from Cloudscape to SQL Server and
added the following entry into my weblogicCommerce.properties file

# ---------------SQL Server ----------------------#
commerce.usermgmt.RDBMSRealm.driver=weblogic.jdbc.mssqlserver4.Driver
commerce.usermgmt.RDBMSRealm.dbUrl=jdbc:weblogic:mssqlserver4:wlcsDatabase@WEBLOGICSRVR01:1433
commerce.usermgmt.RDBMSRealm.dbUser=sa
commerce.usermgmt.RDBMSRealm.dbPassword=mcpassword

After doing this, the commercePool (Connection Pool) that comes with the installation
of the Commerce server did not work and came up with some java exceptions i.e.

Could not create pool connection. The DBMS driver exception was:
java.sql.SQLException: Can't open a socket on none:1433. Check host and port num
ber and make sure the security manager allows this connection. You can also try
running the SocketApplet (java.net.UnknownHostException: none).
at weblogic.jdbcbase.mssqlserver4.BaseConnection.prepareConnection(BaseC
onnection.java:176)
at weblogic.jdbc.mssqlserver4.Driver.newConnection(Driver.java:32)
Can any one give me an idea on what I need to do to resolve this problem?
Thanx

hii..did u change the startup and bea/wlcs/bin/win32/set-environment.cmd
files where u need to change the classpath related with SQL Server.After
that you will have to change JDBC setting thru console using
http://ip:7501/console/index.jsp
Do that and hope it will work.
