Multi-user -application

i want to create an application , installed at a windows
2000 server with multiple access for many users.
the application should run at the server. but the gui should shown at the client. i dont want to use applets and there should be no installation or plugin at the client-
side.
what should be the best technique?
thanks a lot
greetings povray

Thanks
i have found an answer for my problem. there is the java web-start-project.Found at java.sun.com.
you have to download this file and install at your client. but after this you can start any java-application over the net like an client-server-connection .

Multi user application control data access

Dear all,
i am using Oracle Developer Suite 10g and database 10g, windows xp plate form.
i want to develop multi user application regarding education.
i have two questions.
1. i take a start from creating an HR database which have 30 tables.
this database has 10 users.
the users will log on from their own schema.
how they will access the HR schema?
should i create a public synonym for each table in the HR Schema?
or should i create a view for each table in each user schema?
or should i grant select,insert,update etc to each user on HR schema?
2. i want to control the data access for each user.
i.e. every student could access his own academic record. each teacher access his own related record, the manager the owner and so on.
how to accompolish this task? oracle roles are not sufficient for this purpose.
Your help is highly appriciated.

How about you start with the basic stuff, like the 2 days developers guide:
http://www.oracle.com/pls/db112/to_toc?pathname=appdev.112/e10766/toc.htm
and make it to the advanced developers guide:
http://docs.oracle.com/cd/E11882_01/appdev.112/e25518/toc.htm
and work your way through the concepts manual:
http://www.oracle.com/pls/db112/to_toc?pathname=server.112/e25789/toc.htm
and everything else which sounds interesting to you in here:
http://www.oracle.com/pls/db112/portal.portal_db?selected=5&frame=
As for your first question this should be covered here:
http://docs.oracle.com/cd/E11882_01/network.112/e16543/authorization.htm#BABHFJFJ
i want to control the data access for each user.This is also documented:

How to create a multi-user application

Hello,
I have an Application developed in Portal3.0.
I have used portal30 schema where I created this application.
Now, how can I make this application accessible to multiple users? where should I create these users/Roles? How can I give grants on some of my Application Objects(Forms/Reports/Dyn. Pages).
Your help is greatly appreciated.
Thank you.
Sincerely
Madhav

Hi,
If you look at your application from the Applications tab in the Navigator view, you should see a link called 'Grant Access'. If you click on that, you will have the option to give users access (manage - where they can build stuff; execute - where they can just run stuff that you build, etc.) to your application. You also have the option to publish your application as a provider in this screen, so that your forms/reports/etc. can show up as portlets.
Hope this helps.

Applications with multi-users?

Exist there downloadable example apllications witch use multi-users managed by sessions Beans.

Thanks for your answer.
Another questions...
I have problems with my multi-users application (like you saw it). In fact, sessions mix between them.
1) Do you know if there are any configuration for sessionBean to accept many users?
2) Do you know if it's possible that tomcat or sun apllication server mix the sessions?
Thanks

Application contexts in multi-user environments

[Oracle9i Enterprise Edition Release 9.2.0.3.0]
Hi,
I'm experimenting with application contexts as a means of utilizing bind variables in variable WHERE clauses.
In a multi-user environment where the database is accessed from an application using a single user id, are there any conflicts involved when the same procedure is accessed multiple times and the same context variable is set to different values by each call? In other words, can I assume that between the time the user_id of my_context is set and the query is executed in procedure call 1 that those values will be used and not be affected by other procedure calls also setting the user_id of my_context?
Thanks,
Ed Holloman
================================================
create or replace context my_context using my_proc;
================================================
In procedure call 1 to my_proc:
================================================
my_query := 'SELECT * FROM my_table ' ||
'WHERE user_id = sys_context(''my_context'',''user_id'')';
dbms_session.set_context('my_context', 'user_id', '12345');
OPEN my_refcursor FOR
my_query;
================================================
In procedure call 2 to my_proc:
================================================
my_query := 'SELECT * FROM my_table ' ||
'WHERE buyer_id = sys_context(''my_context'',''user_id'')';
dbms_session.set_context('my_context', 'user_id', '45678');
OPEN my_refcursor FOR
my_query;
================================================
etc.

A quick little test shows John's statement in action:
sql>create or replace procedure test_procedure

6    dbms_session.set_context('TEST_CONTEXT', 'VALUE', to_char(p_value));
7    open p_rc for select sys_context('TEST_CONTEXT', 'VALUE') from dual;
8 end;

Multi user access in Single application file

Hi,
Is it possible to work Single application but multi-user access in Indesign CS6.
If yes, Please let me know how to access.
Thansk,
Uvaraj S

I'm not sure exactly what you are asking. InDesign files can be edited by only a single user at one time, but any user can open a file not already in use.

How to make multi user drawing application

how to make multi user drawing application in as 3.0

I'd suggest using Flash Media Interactive Server if you wish to make this type of application and use Flash as the interface. I can't give you the details on exactly how to implement it, but using Remote Shared Object and FMIS would serve as the basis. I believe that the package comes with examples of Shared Objects that can serve as a simple basis from which to proceed. After that you might want to see if you can find an available whiteboard app that can be leveraged to do as you wish.
I apologize in advance if using this type of solution is a non-starter, I've been using FMIS locally and have plans to eventually implement something similar to this type of drawing app as well.

File Discrepancies for Multi Users

Hi ...
We are running RH7 and RSC3.1 with 3 users - We identified
(only yesterday) that after User 1 had deleted one topic file from
Project Manager and added several others ... User 2 and 3 had
broken links for these topics.
We are able to update existing topics by one user, who check
in, then user 2 and 3 can get the latest version and instantly view
the changes - lovely!! Exactly what we would expect ...
But the same is not occurring when we remove or add entire
topics to both the Project Manager and the TOC ...
User 2 and 3 see the topics in the TOC with the dreaded red
cross through them ... and have to try and locate the file or
restore broken links etc ... to get their view of the project in
sync with User 1. This seems to defeat the whole purpose of being
able to have a multi user authoring environment????
A major concern of this problem appears to be the risk of
undoing each others work by potentially restoring files that
another user intended to remove ...
Is anyone else experiencing similar issues ... we are in a
big organisation and are very restricted in terms of our ability to
access the servers etc ... but I want to know if there is something
we should be checking or doing differently from an application
perspective? Any advice or ideas are greatly appreciated...
Many thanks ...
Frustrated!

Hi Fi@qldpol, and welcome to the board. With your situation,
there are two likely possibilities:
1. Was your project added to source control via RoboHelp, or
was it initially added using RoboSource Control? If it was added
from RoboSource Control, then that is the problem.
2. If #1 is not the problem, then you might be having
problems with some of the users' CPD files. First, have everyone
make backups of the local version of their project (the files
actually residing on their PCs). Then have User 2 and User 3 delete
their copy of the project, and replace it with a copy of User 1's
local files. Before they open the project, they should delete the
cpd and pss files. After they delete those files, they can open the
project as usual and let the cpd file rebuild. We have to do this
every so often with some of our projects to get everyone
synchronized.
Hope that helps.

If anybody having idea reg. this issues pl...help me..
Thanks in advance

Hi. A JDBC connection pool is a set of identical, interchangeable, pre-made
connections, and the controls to make sure only one user uses a particular
connection at any one time. If you want to have different DBMS users, you can
have a separate pool for each DBMS user, which may contain as many or few
connections as you want. Some applications has a pool for the accounting
applications, and another for the sales applications etc. Some do have a
separate pool for john, jane, joe etc, each with one connection. Pools
can be created and destroyed dynamically using the dynamic pool API.

Multi-entity application

Hi there,
I'm developing a multi-entity application and I'm not sure how to optimize the data base. Let say big tables for each entity will have 15000 rows per year and we are expecting at least 150 entities, so we are talking about 2250000 rows per year. It´s a web application and we want an optimized response, there are complicated queries with a lot of JOINS so we did some test and it´s a bit slow.
well, we thought in two options:
1.- a column in each table to indicate the entity: tables with 2250000 rows each year.
2.- each entity connects with a different oracle user wich contains its own tables (big ones): 15000 rows per year but 150 users.
I asked about this, someone told me that 150 users wouldn't be efficent becouse oracle would spend too many memory to manage it (I dont know).
Any answer will be welcome
Thanks!
PD: sorry about my english, I´m spanish ;-)

So, wouldn´t you suggestuse a different user for each entity?
Imagine you have 10 tables, 5 of them have around 15000 rows per year and there will be 150 entities like that. we thoght of using a different user for each one just for the eavy tables, and keep the rest of tables in a common schema. So the entity A access with the user A (all the schemas have synonims to the common schema).
Ah, It´s a web app.

An OS-Intergrated place to store per-user application configuration files.

A Chairde,
I'm developing an application that could be deployed on multiple platforms. I'm looking for a location to store per-user configuration files in a OS-integrated way.
I use a utility class to determine the OS of the users machine. I know from experience that Windows NT5+ likes to store per-user settings/configurations in the %APPDATA% path (which is usually C:\Users\<username>\Appdata\Roaming\<vendor>\<software> etc.) I'm using a call to the environment labels to determine it's location.
I'm a linux user myself, so I'm aware that most UNIX based Operating Systems like to store personal configurations in hidden folders in the user's home directory (ex /home/<username>/.<application> etc.), Obviously, I'm using a call to the system property user.home to determine that location.
My Question is in relation to Mac OS and Mac OS X, where would it be a safe location to store per-user configurations? I know OS X is BSD/UNIX based so is it safe to assume to store them as a hidden subfolder of the user.home directory? What about Mac OS classic? Where are per-user settings stored, or is it like Windows 9x and NT4 and lacks proper multi-user setups (although NT4 is somewhat more prepared then 9x) ?
It would be much appreciated if anybody has any ideas.
Is Mise,
Seán Mac Aodha
PS. I'm not using Javas Property files etc. I've rolled my own exchangeable format for storing key,value pairs.

I've used databases in the past to store local files but clients have sometimes run into trouble when the database daemon goes down or doesnt start-up normally because of a "improper" shutdown etc.
In my own implementation of "Settings Files" i have serialized hashtables marked with appropriate metadata stored to the users "application data", a backup or original copy of those settings in the common directory shared by my application framework and then in a networked enviroment, the Settings can be hosted on a database server, so the user can travel between client machines and keep their settings (and files) with them.
I have, with a bit of googling, come across the most obvious page i should have looked at in regards to Apple Mac OS X
http://developer.apple.com/documentation/MacOSX/Conceptual/BPFileSystem/Articles/WhereToPutFiles.html
According to Apple's guidlines, the most suitable place to store User configuration files is in the ~/Library/Application Support/<Application Name> directory.
and for System-wide configuration files, /Library/Application Support/<Application Name> rather then storing them with the application in the /Applications directory.

Jdev11g: Has anyone developed a multi -langual application successfully?

Hi,
In our application the user can change the language of the application by selecting it from as drop-down-list.
This works fine if we run the application with embedded WLS.
But running it on external WLS the language switch does not have any effect.
We have already filled bug 7588599 for this issue which is also reproduceable from Oracle Support.
At the moment I do not know a workaround.
I can't believe that there is nobody out there who has already been successfull with a multi-langual application on external WLS?
I hope to find a workaround in this forum to avoid waiting for backport patch.
regards
Peter
Edited by: hofespet on Nov 26, 2008 7:18 AM
repost

Hi,
problem is solved!
Excerpt from the SR:
Development did find the cause of the problem. The framework does lookup the language files in a specific format. That is the language must be in lower case and not in uppercase. In this case the file system is case insensitive since it is windows, so the exploded app just happened to work since it was finding the file on the file system. When deploying the application the file is being looked up by the jar/zip-finder which is working case-sensitive and thus it cannot find the file "startBundle_en.properties".
The application should name the resource files exactly how they will be looked up by the application and by the ResourceBundleManagerRT.
Rename the file "startBundle_EN.properties" into "startBundle_en.properties".

Peter

Aperture as a Multi-User Digital Asset Management Tool

Does anyone have any experience using Aperture in a multi-user environment? I'm trying to compare it to Cumulus by Canto which is designed as a multi-user tool.
I realize that each user would have a copy of Aperture on their Mac, but are there other issues that are not such as multi-variable searching capabilities of one versus the other. My gut tells me that Cumulus is more robust and can handle much larger libraries as well as all types of digital data and can search within document such as InDesign for a particular image.
Thanks
--Mitch

There is no possible way you can use Cumulus and
actually save money.
I don’t expect to save money. I expect to save time finding info, and avoiding duplication of almost everything we have
Stepping into digital asset management is a far bigger
issue than your boss can imagine. Try not to take this
personally, but your initial question about using
Aperture as an enterprise or workgroup DAM suggests you
have no idea what you're suggesting or possibly getting
into. Canto is all smoke and mirrors unless you can
afford the training and have dedicated, competent and
engaged support personnel.
Nothing taken personally. The question was asked because management is promoting Aperture as the end-all and be-all of imagement, whereas I’m looking for a tool to manage all our documents
Before you go much further, you need to understand
databases and you need to understand that DAM's return
on investment is not about saving money, it's about
preventing the spending of money; a huge difference and
there are few mgrs who can parse that difference from
the sales hype. Buy a copy of "The DAM Book" and try to
get someone to explain databases, cataloging
applications and server-based storage to you.
I understand databases quite well, but I will get a copy of the book you mentioned. I am running an Xserve in my environment, so I do understand servers and OS X Server.
I wish you tremendous luck and hope your experiences
are better than most of the Canto customers I have ever
met, including me. You just have no idea how expensively
wrong your decision to employ Cumulus could turn out to
be. Not that it's a bad product (although we thoroughly
despise it); it's sold as a miracle. Cumulus is a
supremely complex (not necessarily complicated),
over-designed and totally un-Macintosh application.
What version of Cumulus are you using, and why are you so unhappy with it? May I contact you off line to discuss this?
Thanks for the reply

Multi user calendar in CRM

Question - does SAP CRM have a multi user calendar that all users can read change and make additions to, enabaling the sales manager to arrange sales meetings that do not conflict with sales reps appointments and holidays booked?

Hi Experts,
I have same problem. We create appointment in CRM 2007 and adding the other employees to this activity. When we add other employees to appointment, want to display employees calendar in selected time space. If his/her calendar is empty we can add, else we couldn't.
I searched this application in search engine and found the "Room Calendar". Could we use this application in CRM 2007 UI, if yes how?
Thanks,
David.

Architectural Help - Converting Single-User DB to Multi-User

I have a single-user database running in Java 1.4. I want to convert it to a multi-user database targeted at really small (no way they can buy Oracle) groups. I have a lot of expertise in the old way (file/record locking, avoiding deadly embrace, etc.) but don't think this is right for Java.
What would be a good Java architecture for such a small DBMS? Initially it would be fine to just run a server on a network, tho longer-term it would be great if the solution extended to a remote server on the net. J2EE is not in the cards unless its absolutely required.

Thanks, warnerja.
Here's the issue. The user is viewing a list of names (customers or whatever). Names are physically stored in the order entered; logically viewed sorted on last name, then first. The user drags the elevator car two thirds of the way down. Now what?
Using SQL-based anything, you're pretty much forced to query the table for the whole result set; keep it in memory and then scroll off that. Suppose you have lots of names - 100K or more. This goes dead slow. Worse, in real applications your names will be inner-joined to maybe several other tables so the problem really multiplies.
See MS Access for a good example of how bad this can be. I've got one where the user clicks the down arrow on a combo box and then waits two minutes (actual, measured with my own watch, wait time) for the list to appear. Ugh.
I've created an indexing method I call the b++tree, which makes it perfectly simple to respond to that user action: goto( 66000 ); getNext( 20 ). If my calculations are correct, that goto() should happen in a single disk read and about ten millis.
