JSF support on Oracle 10.1.4 Portals

Hi,
We are planning to use Oracle Portals version 10.1.4
I have read that the new version of Portals can be used to publish JSF as portlets using JSF-Bridge (coming with Web center Suite).
This looks little expensive option..
Does Oracle Portals support use of JSF and struts ???
How about using ADF-struts ??
which is better and is supported in the new version 10.1.4 Portals??
We would like to use JSF specifications for our View components...what will be our best choice on Oracle Portals??
Please let me know
Thank you
Malathi

It will be an expensive one :)

How to incorporate a Language that is not supported in Oracle Portal

Hi,
I want to know the preferred way to add support for a new language in Oracle Portal.
If a language is not supported in Oracle Portal, how I can add the content for that language in the Portal?
Please advise.
Best Wishes.

I've seen this in a statement of direction presentation as an enhancement for R11. So this should be a R11 feature. In the meantime you might investigate the NLS views and tables and try to find a way to extend this. BUT just in an emergency case and you have to know that is not supported (also you may lose support in general for this installation when hacking the repository). So I cannot recommend this with a clear conscience. You have to know exactly what you're doing.
You can also open a SR to get an official statement from support. Maybe there's a note for this.

Hw can i get arabic support in oracleAS using jstl: showing '?????' symbols

Hello All,
I am using OracleAS for portal deployment and portlets UI constructed by using jstl.
i have used spring portlet jstl for the jsp pages.
when i am trying to change the language, it is showing '?????' symbols.
I have used correct unicode. i tested in pluto portal server. when i deployed in oracleAS,
for english not a problem. for arabic it is showing as '????'.
i have used this code to get arabic in pluto. same code i used. i am getting error.
<c:set target="${pageContext.response}" property="characterEncoding" value="UTF-8" />
<fmt:setLocale value="ar" />
<fmt:requestEncoding value="UTF-8" />
i know it is not setting charector encoding.
i tried some other too like:
<head>
<META http-equiv="Content-Type" content="text/html;charset=UTF-8"/>
</head>
and
<%@ page pageEncoding="UTF-8" %>
No improvement. please help me out of this.
how can i get arabic support in oracle AS by using jstl?
Thanks,
Arun

Only Apple Account Security could help at this point. You can try calling Apple Support in Canada - you'll have to find one of the several ways, such as Skype, to call an 800 number from outside of the relevant country - and ask for Account Security and see if they can help. Or you can find a friend who speaks Chinese and ask them to help you talk to Apple Support in China. There are really no other options that I know of.
Note, by the way, that these are user-to-user support forums. You aren't speaking with Apple when you post here.

Details on TAF support in Oracle AS 10g

Hi experts,
I'm currently writing a Master's Thesis on High Availability of Applications based on Suns JEE platform.
With Oracle being one of the big players in this market I'm going to investigate the features of the Oracle product stack and compare it with other solutions including opensource.
At the moment I'm looking for details on TAF-support in Oracle AS 10g. Lets assume one has installed the latest release of the Oracle 10g database in a RAC configuration on two or more physical nodes to store the applications data. Lets further assume one has set up the latest release of the Oracle AS 10g on different hosts building an AS farm with clustered OC4J-instances. Now one would like to connect a JEE application running within these OC4J-instances to the RAC database.
Therefore one can configure an OC4J datasource to use a service definition supporting network failover and transparent application failover (TAF) specified in the tnsnames.ora on the AS hosts or directly describe the service in the data-sources.xml. To my knowledge only datasources configured to use the OCI client can be used with TAF. Everything right so far?
Now the interesting part. The best what TAF can do is automatically reconnect to the next known database node if its current node is not reachable or fails, and continue processing an open cursor for select so that the application can continue to use its current connection.
If the application is running a database transaction it can only be rolled back and rerun after failover.
In a good old plain Java application one had to implement the OracleOCIFailover interface and register a callback with the db connection in order to receive failover events. Therefore you need to process the query in a different thread.
In a JEE server only the container should be responsible for creating threads, or? How does the Oracle AS support TAF? How can a user application get notice of a failover and react appropriately. Is the behaviour always the same no matter one decides to implement the data access via simple DAOs or entity beans (CMP/BMP)? I assume it is safe to use a connection pool and container will take care of the necessary cleanup jobs, right? Will the complete connection pool be reconstructed or only connections to the failed node?
Does the application server internally use these OCI callbacks and wrap them up into special Exceptions? Is there anything an application programmer has to do in order to make his data access code ready for TAF, especially in case of failover while the db is processing transactional code?
Any insights and/or code snippets would be greatly appreciated!
Ah, one last question. From a HA perspective is it generally a bad idea to put application logic into the database (use CDM RuleFrame and so on) as there is no support in preserving package states or do you think this makes no difference as one has always to repeat everything since the last commit point no matter in which tier the code resides?
During the next days Im going to set up the above environment for testing. A 10.0.2.1 RAC on RHE4 is already up and running fine. AS 10.1.3.0.0 on RHE4 is following today or tomorrow.
Many thanks for all answers!

Eric

Hi,
well, I thought I could dig into the OC4J documentation before installing the server. After reading the OC4J Service Guide for 10.1.2 and 10.1.3 I'm a little bit confused.
First I read the 10.1.2 Service Guide and almost everything seemed to be clear. I found a lot of answers to the questions above. I'd like to sum them up. Please correct me if I got something wrong!
- TAF only works on top of OCI driver
- TAF can be used with connection pooling
- OC4J takes care of connection pool cleanup (OC4J and OCI Pool)
These two pools are mentioned. It's not clear to me how they work together. Do one of you know some source where I can get more information about this?
- after a failover all connections in the pool are checked by OC4J and only alive ones will survive
- in case of a failover TAF issues an exception
- the application has to catch this exception and acknowledge with a rollback, after that the transaction can be restarted (this seems to be the responsibility of the applications code, oc4j will not replay something automatically; If I got it right, CMP entity beans will be an exception to this rule - there OC4J will proceed transparently...)
- the application can use OCI callbacks to customize the failover behavior (well I would like to see some source code example here, as I can't imagine how this could look like)
After that I read the 10.1.3 service guide. The section about datasources in conjunction with HA is much shorter. Besides TAF new? mechanism is introduced, namely Fast Connection Failover (FCF). There is not much information about it but references to the JDBC Guide, because FCF is a feature of the implicit JDBC connection cache. Where cache seems to be just another word for pool.
By the way, the example on p. 4-36 looks wrong at first glance. Enabling FCF and setting:
<property name="fastConnectionFailoverEnabled" value="false"/> ???
Seems to be a typo in the docu, or?
I got the impression, that the text is written as if FCF being TAF's successor, without explicitly saying this. Is this right?
So I proceeded reading the JDBC Developer Guide to lean more about FCF. Here is what I learned:
- since 10g available
- FCF is driver independend (you can also use the thin driver)
- prerequisites are implicit connection cache (pool) enabled, ONS must be configured
- in case of a failover the transcation will be rolled back automatically (not by the application); whereas using TAF you have to use a rollback to acknowledge the error
- only one exception ORA-17008 to catch
- application has to obtain a new connection from the cache (pool), where as using TAF the old connection object can be used, and resend the transaction (same as with TAF)
So when to use what? The comparison on p. 27-8 was not very helpful to find an answer to this question.
On p. 28-1 one can read that TAF does not work with the OCI Connection Pool. That's seems to be contradictory to the statement in Service Guide of 10.1.2 that OC4J takes care of both pools (OC4J and OCI). Or has something changed in 10.1.3 in that regard? May be this is because of the changes in Cache or Pool Management?
What is the advantage of using TAF within OC4J in 10g, if there is any?
What about select statements with FCF? You can only read about transactions. I'd assume the application would get the same exception executing a query (ORA-17008) as executing a transaction, right? So TAF should have the advantage of transparently proceeding selects after a failover. Am I right?
I'd love to see more examples and comparisons of TAF and FCF.

Eric

Hindi as NLS Language and territory parameters. I have also
tried configuring them as 'UTF8' a character set prescribed for

to insert any rows with these charactersets in NCHAR or NVARCHAR
columns. if i try to insert them in regualr char pr varchar
columns i can insert in the ascii formats and I have to retreive
them on front end through different mask format fonts.
If any one have tried the NLS support pls let me know how to
insert the records and retreive thenm in the national language..
Thanks in advance..

JDK/JRE Version support for Oracle Lite

Hi,
We have developed an application using jdk 1.4.x which also using Oracle9i Lite 5.0.2 release as a database. Application behaves normal except while closing it throws java exception (Exceptio Guard Page Exception) error.
Is it because of the JDK Version we are using? What is the JDK/JRE version level supported by Oracle Lite.
Thanks
Krishna

Right
I got the same problem too.
When my program and oracle 9i lite is running under JRE1.3.1, everything is ok.
However, when i migrate the jre to 1.4.x, the program must fail and report DLL exception after closing.
So trouble~!

Is Forté UDS version 5.1.3 supported on Oracle 10?

Hi,
in the company I work in we've got applications developed in Forté UDS 5.1.3 and we've got Oracle 8.1.7
We're going to change Oracle version and we'd like to upgrade towards Oracle 10.
Someone has told me Forté UDS 5.1.3 is only supported on Oracle 9 and not on Oracle 10. Do you agree with that? Can you help me to undestand whether it's true or not?
Thanks in advance!
Edited by: Mark1970 on 19-mar-2010 3.05

There are documentation and certification matixes provided at http://docs.sun.com/app/docs/coll/S1_UnifiedDevelopmentServer_35
Why not look there.. and contact Sun support to clarify?
From a pure client-server perspective - the Forte database interface for Oracle supports need to support OCI (or JDBC) as communication interface to Oracle. The question thus is whether or not this interface can use the later OCI driver versions (9i, 10g, 11g). As a 9i OCI client can for example connect successfully to a 10g or 11g database instance, Forte can likely be used with such a client to connect to a newer Oracle version.

FDM is not supported on Oracle RAC? Why not?

[http://download.oracle.com/docs/cd/E12825_01/epm.111/fdm_11113_readme.pdf|http://download.oracle.com/docs/cd/E12825_01/epm.111/fdm_11113_readme.pdf] We are in the process of implementing Oracle Hyperion Financial Data Quality Management (FDM) version 11.1.1.3 as part of our Hyperion Essbase BI environment. I read over the documentation prior to building the databases, but apparently I missed an important bit of information. It seems that FDM is not supported on Oracle RAC. I just noticed this under in the "Known Issues" section of the FDM 11.1.1.3 release notes, and that was only one sentence. The release notes do not explain why this is the case.
- Does anyone know why FDM release 11.1.1.3 is not supported for Oracle RAC?
- Has this always been the case?
- Can a single node database, running on an Oracle 10.2.0.4 two node RAC environment, be used instead of building a separate, stand-alone database?

Java multithreading support in Oracle JVM

Dear all,
I have some questions and observations regarding multithreading support in Oracle JVM. I have some java code that is stored in the database and is multithreaded (in separate threads I run a plsql procedure that does a lot of precessing). If I run the code with my standalone JVM it works like a charm, everything gets executed in separate threads. But if I store the code in the database and run it (with the custom JVM Oracle implemented for the server) it does not do any threading, all I have is a single thread that runs everything sequentially.
The logic is this: using JDBC I create a connection, get a parameter (number of threads) and then launch the threads (each thread creates its own connection and runs the plsql procedure). No resource is shared (I have no synchronized code, I do not yield).
My question is: does Oracle JVM supports multithreading or not? If yes, how to achieve it? Maybe there is something handled in JDBC? (although my code useses JDBC is not multithreaded) If this is not possible with java, do you now how to run something (oracle function, procedure) concurrently with PLSQL? (I tried with DBMS_JOBS but it does not work on all my databases and our DBAs discourage the use of them). Performing multithreading my launching different sqlPlus processes is not an option (as we have no security standard regarding the authentication -> connection is made by specifying in clear text the user and password).
I wanted to use java because is more simple, secure (the connection is already established as the classes are stored in the database) and easy to maintain (until now we use different scripts which run on Unix and Windows and this leads to double work).
The Oracle versions I use are 10g and 11g.
Thank you all very much for your time
Just the best,
Don

(Obviously the other post answers your question.)
If I am reading that correctly then you have a management issue - not a technological one.
You have a task to complete, presumably doing it efficiently is something that the company wants.
And you have two alternatives both of which the DBAs are not allowing you to use.
So at that point it is up to management to insist that the DBAs provide specific technological reasons (not hand waving) why those solutions are not suitable. And they should also be required to provide the outline of an alternative that is suitable.
Besides that you might consider why your solution cannot be implemented entirely in a single threaded PL/SQL routine. The fact that is harder is not a reason when the point of the excercise is to create something that is more efficient.
