How UTF8 Session???

Hi,
after trying the oracle documentation, I have to ask you now, folks. How do I change my session to support the UTF8 "Database" character set. That means, I want to be able to store UTF8 characters in normal varchar2 fields and don't have to change a thing on my database.
According to the documentation this should be possible through a kind of
alter session set nls_????='UTF8';
statement. Exactly this information is to me a lot too scattered in the documentation and I couldn't find it, so could any one of you help me find the right parameter?
Thanks a log in advance!

The Choosing a Character Set chapter of the Globalization Support Guide is probably what you're looking for

Particularly the section on changing the database character set
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96529/ch2.htm#101203
and the section on what characters a character set supports

The Java Programming in a Global Environment chapter probably answers your JDBC questions.

How many Sessions can I invoke?

Hello experts,
afaik there are some limitations regarding how many sessions I can use simultanously for web service calls. I think I saw some information in this forum, but I do not find it again :-(.
I know the "20 requests per session" rule, but how many sessions can I create?
Thanks in advance
Michael

In the web service document you can find the number.
In the old document you could find a session limit of 2n+10 where n is the number of users.
The new document has no number of sessions but limiters in traffic

How many sessions would I need for BBP?

Hi friends,
I am going to work on preparing a BBP document for Benefits implementation. Could you please guide me on how many sessions of workshops would I be needing for different components of Benefits module? I need to prepare presentations for each session. So, it would be great if you could also help me in dividing the module components into different sessions.
I have to perform these activities for PA and OM modules as well.
Your guidance would be a great help for me.
Thanks in Advance,
Sanjay.
P.S. - Appropriate points will be awarded.

Hi,
Preparation of blue print comes after you gather all the requirements, discuss the gaps with the clients. Gathering the requirements and mapping them to SAP will be done in series of workshops. You may have two workshops for each module and two workshops to discuss integration requirements. Once you are clear on the requirements and the Gaps, plan for a workshop on initial draft blue print discussion. This discussion would be for the design and content of the BBP. Later one workshop to present the complete blueprint to the client whci would include all the main stakeholders of all the modules. Later small changes can be made with individual discussions and go for sign off.
If you are particular abut the number of sessions, it depends on the complexity of business requirements. If the requirements are many and complex in nature, you need more sesions to understand the scenarios completely. Once you are clear with the AS IS and TO BE, preparation of BBP will become an easier task.

How many sessions does SAP allow you to have ??

Dear Memebers,
How many sessions does SAP allow you to have ??
a) 3
b) 6
c) 9
d) 12.
I guess the right answer is B and C but in choices I have to select only 1, which answer will you pick and Why ??
Thank You.
Madhu.

> I wanted to know for sure what is the answer.
Hi Madhu,
If you are going to ask questions such as these, then please indicate that you have searched and what you do already know and where & why you have a doubt somewhere which is worth discussing in the forum or sharing opinions or experiences on.
Just asking for the answer only so that you don't feel too alone when answering 6 in the interview is of little value.
Normally such "answer a, b, c, or d only or be quiet"-type-threads (like certification tests are) are deleted. That is the rules, and we have them for a reason.
Anyway, you guys seem to have sorted this out amongst yourselves so there is no reason to interfere here IMO. Thanks for that.
Cheers,
Julius

How many sessions can open at a time for 10g DB

Hi,
My App Server is connects with min 200 users , But from last week onwards
we are facting automatically disconnecting to the app server.
What was the problem we don't know .
Let me know how many sessions can open at a time ?
Thanks,

You need to capture any connection errors from the app server.
Otherwise we're just guessing.
The SESSIONS parameter restricts the number of open sessions (select * from v$parameter).
Presumably you're using DEDICATED server connections rather than SHARED server connections?

How are session timeouts handled

Hi,
Can anyone tell me how session timeouts are handled by the Servlet
Engine.
What is the exact role of the SessionInvalidator class. Are sessions
correctly timed
out by iAS, because I get strange behaviour in handling session timeouts
in my application
which is following MVC architecture.
What I am observing is that sessions dont seem to timeout after the
length of
time specified and sometimes they do timeout correctly. The difference
between the
time the session should have timed out and when it actually does is too
high, which is
really a concern for us.
Thanks in advance to evryone.
Amar bhat.

Hi AmarBhat,
Actually this is a bug in iAS (bug id: 556909, Status: Fixed ). This is
happeninig because iAS has a bad ( late) cleanup of timed out sessions. The
getSession method (HttpSession) calls IsRequestedSessionIdValid() as a check
for timeout and this check returns "Valid" even after a couple of seconds of
timeout. Thus, the getSession from Java layer returns the valid session. So
you are still able to read and write data on the session.
We can specify iAS the session to invalidate itself after being timeout.
Alternately, we can do it manually with HttpSession method, invalidate().
Plese get back if you have any issues.
Thanks,
Rakesh.
Developer -support, iAS.

How Stateless Session Bean instances in pool

Hi,
I am not clear about , stateless bean having "pool" of objects to be used by multiple clients.when those instances will be created or who will generate them.
Is this pool specific to ejb container or any vendor container.
thanks in advance,

Hi , my question is about Stateless Session Bean ,
how StatelessSession bean will behave when some 100
clients wil call homeObject simultaneously.The EJBs(including stateless) are single threaded so one client can access one Bean at a time. As per your question if some 100 clients are invoking home.create() method then it has to invoke on 100 EJBs. The instance pool size can be specified while deploying. In the descriptor (application server speific). So if the number of simultaneous clients is more than the pool size then some clients have to wait.
Now my second question is how and who will create
these instance .The container will create the pool as per the application server spcific deployment descriptor.

How far session.setAttribute("user",user) is safe for login checks

hi,
i would like to discuss how far the method of session.setAttribute() can save
unauthorized access of pages. as far as i know when a user logs in we set a
session attribute say user and set its value to the entered username.
To prevent the unauthorized access of inner pages i would check at the beginning of every page whether the user attribute is null or not by getAttribute("user") method. if it is null i wont allow the user to open the page.
Can i rely on this strategy to write my web pages or does it have any bugs through which user can hack the page or any other better way to secure the pages.
thanx

That's pretty standard. I wouldn't go so far to say it couldn't be hacked, but generally that would require some bug in your login process or direct access to the server and it's memory. The latter certainly isn't possible remotely. The former, as long as you know that the attribute can't be added when it shouldn't, then it should be fine.

Hi,
I am not clear with ur query..
What I understood from ur query is that, u are trying to put the session ejb in the HttpSession Object for some use ahead in future?
If this is the case, then I think are approach is not correct.
StatefulSession beans are meant for this purpose, i.e they will be maintaining the client session. So use the same using the JndiLookup of the HomeInterface and the getting the Home reference and calling the businessmethods

How do Sessions work in Weblogic?

Hi,
For some reason, weblogic keeps forgetting and creating a new session everytime I send a http request. I basically login, and then make a request and it says that I can;t get it because I've logged out. Oddly enough, it doesn't have any problems when I use an IP address. It screws up when I use the computer name, which I thought was exacly the same as using an ip address.
I'm really new to Java programming, but have done a lot of c++.
I'm now adding the the SID (sessionID) to my calls to Weblogic server. eg &SID=blahblahblahasdfsda but it still makes new sessions for me at every request.
Any ideas would be great! Or let me know if you need more info. Can anyone point me to a help section on sessions and weblogic (servlet coding)?

How call session bean from Client side

Hi
calling session bean from client side it gives Lookup erroe, it gives JNDI error
how we know session bean is working. in Admin tree bean statis is reb Flaf, and ID is "Down" how we activate it..
null

If you can make a connection using sess_sh, then you know that you have configured your database and listener properly. If it is not working, read the manuals that you can download from technet. They are pretty good, and if you follow the directions, you should see success.
Good Luck!

How does session bean state replicate?

I can't figure out how state of statefull session bean gets replicated for clustering. Can any one explain how this works?
          Lets say we have two copies of the same bean A and B where B is suppose to be activated in case of a failover. If A has commited a transaction, how does that transaction get carried to B so it can update its status? Does a change to the in running state of bean (one that is not persisted) of the session bean gets replicated also?
          Thanks for you help,
