Browser multiple sessions

Could be possible run multiple browser session (different sessions) from e-Test and e-Load?
Our objective is try to test an application developing with “Oracle ADF Faces” and we need to run load test with different user sessions.
When clicking the IE icon multiple times we are creating MULTIPLE PROCESSES, meaning that IE is running several times. Opening a new window will just spawn another session within the same process but this share the application session.
In order to test our system and avoid session sharing we need create "multiple process" from load tools.
How can we do this?
Any help are welcome.

Diego,
As Alex explained, every virtual user that is executed in eload will run inside it's own virtual browser. Every user will run independent of each other, as though they were executing from seperate machines. There is no sharing of cache, cookies or any other session data.
Your explanation of how a typical real user executes multiple IE processes yet still share session information is understood, but I do not see if there is a technical reason for the seperate processes. Is there some embeded object (i.e. applet) that needs to run as a seperate process? Is the client trying to force a new socket? From you initial description it sounds as though you should be able play your recorded script in a single virtual user container even though there will be no physical process split.

Setup for Discoverer to have multiple sessions opening in different browser

What is the setup for Discoverer or Windows 6 browser to have multiple discoverer sessions opening in different browser windows at the same time in Discoverer 10g Plus?
We have implemented Discoverer 10g Plus just to be used as an extract tool. We have some workbooks retrieving 200,000 or more rows from an Oracle database. It is taking 30 to 45 minutes to download. Some users are able to open multiple sessions in different browsers to download more then one worksheet at the time, but we have other users who get an error message that they can only open one session at the time. What is the setup to allow users to open more than one Discoverer session?

APEX Security: Multiple session cookies in one browser

Hi all,
I use mozilla firefox as web browser. When I open a new tab and enter the APEX application url I will be redirected to the login page. After successfully login I receive the session id and the browser the session cookie WWV_CUSTOM-F....
When I now open the next browser tab and enter the APEX application url I will be redirected to the login page. After successfully login I receive the new session id and the browser the session cookie WWV_CUSTOM-F... with new content. My session from the first browser tab will be killed, because the session cookie for this session was deleted/replaced by the session cookie from the second tab.
Is it possible to have multiple APEX sessions opened in one browser in multiple tabs?
Regards

Hi PaulP,
it's simple.
Unzip bsApex2 http://www.betasoftware.it/codice/bsApex2.zip

Multiple Sessions in CMC for the same user

Hello,
Version: BOE XI R2 SP3
A user opens an Xcelsius Dashboard. As they are using the dashboard, multiple calls are being made through QaaWS to the database. In CMC, we can see multiple sessions created for that user. However, this is not 100% consistent.
Why are there multiple sessions created for one user consuming one dashboard? Shouldn't everything result in one session?
Thank you,
Scott

Thank you Greg,
The user shows multiple session after opening and refreshing just one Xcelsius Dashboard over and over again. It is using QaaWS to get its data.
Also, as you mentioned, we are also seeing problems with Logout. Sometimes, users click the logout, but their session does not terminate. Other times, it does terminate. And, also, sometimes the logout button does not work. The user is forced to just close the browser window.
Any ideas?
Scott

Multiple sessions with Viewer 3.3.61

Hi,
I have Discoverer Server set up on a single machine, using OAS as the HTTP server, and Viewer 3.3.61.
If a user tries to run 2 queries at the same time (opens up two browser windows), one of the queries will be cancelled (usually te first query started).
Why is this? Is this normal functionality, or do I need to set something up for multiple sessions? If I need to set something up, where can I find documentation?
Thanks,
Suzanne

Suzanne,
I think this is normal for Discoverer. It seems to be that there is a session for each user login. Thus a single query for each login. This is just my observation.

How to open Multiple session

I am trying to OPEN multiple SESSION for same application and unable to do this using FIREFOX 7.01
R 12(Oracle E-Business Suite), we are using FIREFOX for several clients to open the applciation. But i cannot open different session of same applcaition. it is ONLY opening singel JAVA form. In IE 8 or 9, i can do - NO MERGE option or File>New Session option. Is there some workaround for this. I am using Windows 7.

Hi,
When you run the form in the browser, it opens a new database session. For sharing the same session, you need to open/call/new form within the form itself.
For using same JVM, you can use the [JVM Pooling|http://download.oracle.com/docs/cd/B14099_19/web.1012/b14032/jvm.htm] feature (assuming you are on forms >= 10.1.2).

Multiple session issue

Hi,
I have created SAP transaction ivews in my portal with SAP Logon tickets to connect r/3. End users are having tendency to open multiple browser window using Ctrl+N. This way they dont have to login many times and can have many portal window open.
The problem here is for each new window opned with Ctrl+n it opens a new session in R3. this way there are so many sessions are opened in R3. Is there any way we can prevent multiple sessions in R3?

Hi Rick.
I also meet with the same problem , situation.
We have tried with parameter
login/disable_multi_gui_login
but it does not work if login come from EP SSO.
When user open backend R/3 from EP SSO, it will not be considered as a new connection, so the parameter validation does not work.
I check the documents. EP has some session management methism to control the too much sessions to backend system.
And in our project, our solution is that we develop a userexit in R/3. When user login in R/3 from EP for more than 1( the number can be changed as u want ) times, the R/3 will tell user that he can only connect to R/3 for one connection, he can go on ( terminiate the old one ) or quit current.

Creating / Handling multiple sessions

How can I create multiple sessions with Servlets/JSP?
The requirement is this:
An admin-type user logs into my application. There, he can see a list of normal (non-admin) users, and should be able to log into those users accounts. Therefore, it is necessary to start a new session as this user, while the he should still be able to be logged into his admin account (and log into more users accounts, if need be). So, the admin session must remain valid, and for each login into a user account, a new session must be created.
I understand that this is not possible using the standard cookie-based approach, so I turned them off for the respective context in Tomcat and encoded all URLs using <c:url ...>. Still, I don't know how to start a new session, there seems to be no method to do this. When there is an active session, getSession(false) returns it, that's all I get. So how do I create a new session with a new session id?
While trying to figure this out, I also noticed some odd behavior in Tomcat (Version 6, though this might apply to other Tomcat Versions or even other web containers. If no session is yet active (like, on the Login page of the application), or the active session is being invalidated (as after logout), a new session is created every time one of those pages is accessed. This also happens if no session id is given at all in the URL (and, probably, if an expired session id is submitted, I didn't try this one yet).
This is not good, simply speaking. This way, the web container will quickly get swamped with ghost sessions that were, on my part, never created, and never used; still, they hang around until they expire, of course.
Any ideas? :)

Bad approach? Could you elaborate please? :)It is just plain cumbersome and coding is impossible without horrible hacks.Hm, why cumbersome? The only difference between your approach and mine is that I would use two seperate sessions, as if the user had logged in using his username and password, while you would use one session for both.
As for coding, I see no need for hacks. The admin is supposed to be able to create users, enter/change some contact data and do some settings for the users accounts, and log in as that user (without having to ask him for his login credentials) for support cases etc. Where is the need for hacks here? Except maybe if there is no way to create a session from another session...
but it wouldn't allow for an admin to look into more than one user account at once (right?) which is somewhat a requirement.So you want to impersonate more than one user simultaneously? What's the benefit of this? If you want to switch between users, just go back to the admin panel and pick another user.Yes, or rather, support staff will want to do this.
This is a common scenario in the company I work for, where 3 support people serve about 1000 active customers (of another, PHP-based project). Customer calls, a supporter will use the admin account to log in to his account and have the problem explained. If the solving takes longer, he will tell the customer that he will look into it and call back when it's sorted out. Now while he is working on this, the next customer calls, so the supporter will use the admin account again to log in this account, also, to have the problem explained etc. If the second problem is solved quickly, he will then just log out of the second customers user session and simply continue working on the first customers problem which is still active in another browser window.
Now, if the support people can have only one user session open at a time, they will have to close the first customers user session they were working in (probably having to save some work only halfway done) when the second customer calls, log in to that second customers account, help him, log out of the account to go back to the admin panel, log back into the first customer account, resume work there.
Long story short, while the first approach enables them to do small tasks on the side while working on a bigger problem, this is not possible in the second approach.
Still, any idea about the rogue sessions when I wrote about in the last paragraph?I don't understand your doubt. Every request should take place in a session. If it isn't there or if it is invalidated/expired, then the appserver will create one. I don't see how that is a problem.Ok, if this is normal behavior, then no problem. I just got suspicios when sessions kept appearing while I was not creating any myself.

How to deal with multiple sessions?

My application has requirement that number of users can log simultaneously. They can search documents, browse the site, etc. Now the funtions they can perform depend on their user type. So to keep track of their userids and usertypes, do i need to create different sessions for each of them?
If yes, how do i tackle such a multiple session problem? ( Say if an user of type A clicks the search documents button, how do i know which session he belongs to?)
If no, what else can i use?

Hi,
You only need to maintain different user types and assign one or more types to your users. You can have another table that say what privileges each user type has. Then the first time the user logs in, you fetch this information and store it in your session. Then when the user tries to do something, all you do is get his user type and see if the user type has permissions to do that specific action. You then allow or disallow him from doing the action.
Hope this helps.
Cheers,

How to avoid multiple session for the same username

I need suggestions on implementing single user login , like My system has a user with a username jdavid and my application should not allow two different sessions for the same username jdavid , can one session peep into all other session
to see if the any has a usernaem jdavid, I am basically looking for some pattern if any available for restricting multiple session for the same username . like jaas or any other security api provides this ?

Store a Map<User, HttpSession> in application scope and let your application intercept on that. On login, just check if the User is already there, then get the associated HttpSession, invalidate it and replace it by the current HttpSession, else just store the current User-HttpSession pair in the map. On logout obviously remove the User-HttpSession pair from the map.

Multiple sessions in a single database connection.

I have copied the following text from Forms Developer2000
"At runtime, Form Builder automatically establishes and manages a single connection to ORACLE. By default, one user session is created for this connection. However, the multiple-sessioning feature of ORACLE allows a single client to establish multiple sessions within a single connection. ORACLE transaction-management and read-consistency features all are implemented at the session level, so creating multiple sessions allows a single user to have multiple, independent transactions."
If ORACLE allows a single client to establish multiple sessions within a single connection, I want to leverage on this feature in my application which uses BC4J.
Can anybody tell me if
1. its possible achieve this in Java(BC4J).
2. If Yes, How?
regards,
vikrant

Thank you for your valuable suggestion.
I believe createing multiple root Application
Modules, will create as many number of connections to
database, hence multiple transactions.
But What I wanted was multiple sessions in a single
connection, who's behavior will be similar to two
different connections.Could you tell me the advantage you're looking for in multiple sessions in one connection vs. multiple connections (where connections may be pooled)?
Thanks.

How do I create a program with multiple sessions?

I need to allow multiple sessions with this program.
I realize that it involves threading of some sort, but I'm pretty new to this area and am not sure how I should go about this.
Here are the instructions:
"�     Write an application that will create an online dictionary a data file will be supplied that contains a list of words and their meanings. The hash table will contain a key (the word in question) and a value (byte offset of the word meaning stored in a random access file). You will also provide methods for entering, searching and deleting words online. The program must allow for multiple sessions."
I have most of this all done, and have a dictionaryBroker ready to write the add, delete and search methods.
But what about the mutliple sessions?
I'm thinking that my hashTable and RandomAccessFile classes are both going to have to be singleton.
What I want is for multiple people to be able to run the program at the same time, but if one person adds or deletes a record, I want it to update instantly for everyone.
But it also needs to run smoothly for everyone using it.
Thanks for any help, I just need a little push in the right direction here to help get me going.

Well here is the entire assignment:
     Write an interface for a hash table that satisfies the following criteria:
The hash table will contain a key (String) and a value (Object)
Allow for a specific load capacity, if the capacity is exceeded the table is rehashed. The rehash may be called independently
Must allow for maintaining the hash table (adding modifying etc) the key will not be changed
Must allow for retrieving information from the table
Must allow addition using a Map object or one key, value pair at a time
The addition using a Map and the rehash must be a two pass approach
�     Implement the interface.
�     Write a test routine to test all aspects of the interface. The test must calculate the efficiency of your hashing algorithm.
�     Write an application that will create an online dictionary a data file will be supplied that contains a list of words and their meanings. The hash table will contain a key (the word in question) and a value (byte offset of the word meaning stored in a random access file). You will also provide methods for entering, searching and deleting words online. The program must allow for multiple sessions.
Submission
Submit your eclipse project or executable jar file through WebCT. An efficiency of 70% or better must be attained for the assignment to be graded.
I'm in Canada, not the US.
It says online dictionary, but I don't think we actually have to do that. I'm pretty sure I can just use a simple GUI to allow them access to the dictionary.
So, I'm assuming that I just have to make sure that if multiple people are trying to access it at the same time it needs to update at the same time or something. The hashtable was the main part of the assignment so this part shouldn't be too large.

How to handle multiple session in ADF using jdevloper11g

Hello All
i want to use the form in Multiple sessions.
i have one sign up form. user enter only 4 to 5 fields & he may not fill the the manditory field & he left.but data base dont give the error to him. but next day he will come at the next day to complet his sign up i.e. when he commit the all detail that time all validation will hapen.
for that i use one table without constrain to store the temarory detail.& use other table (with constrains) for final submition.
1) i creat the view n entity for temparory table
2) & also i create views n entity for Final table
n i create one methos in viewRowImple file in that file i overrid create method from using this i set the value from tempary to final table...
but when user left the manditory field then it allow to submit the data in temparory field but when i copy that data to final table(with constrain) n user submit the data then validation happn i.e. "this fild is mandatory".when i click this error message it goes to first screen.
IS Thiis Possible.. in ADF

Generally this can be done.
I see a problem with your use case, which has nothing to do with jdev or java:
How do you identify the user when he comes back to finish the form?
For this you can't use information like session cookie or IP address because they change.
So you have to save some information about the user which lets you identify him when he comes back. All other requirements can be implemented by ADF.

How to open multiple sessions for one user?

Sorry for the silly question but I couldn't find it googling or searching through this forum, so I started wondering whether it's possible in SQL Developer to open multiple sessions for one user. I'm fairly new to SQL Developer and databases in general.
When I open SQL Developer and connect to a schema, a worksheet opens named MYSCHEMA. If I disconnect then connect, another worksheet opens, named MYSCHEMA~1. I assumed these were different sessions, but if I enter into one worksheet:
select col1 from my_table where row_id = 1
-- shows result is 1
update my_table set col1 = 0 where row_id = 1
select col1 from my_table where row_id = 1
-- shows result is 0and then enter into the second worksheet:
select col1 from my_table where row_id = 1
-- shows result is 0I would have expected the second worksheet to report 1 because the first worksheet did not issue a COMMIT. Thus, I'd guess both worksheets are the same session? Is that right? If so, how do I have two sessions open simultaneously (opened by same user)?
I'm trying to implement the code at the bottom of this post, for which testing requires at least two sessions:

Thanks Jim,
Ctrl-Shift-N doesn't do anything for me. I'm on a mac -- by experimenting it looks like command-N does what you're looking for. This appears to be the same as left-clicking on the "New" icon in the top left corner of SQL Developer, or selecting from the pull-down menu, File > New.
This opens "Create a New" window that appears to be a wizard. What would I select at this point? Options are: Database Connection, Table, View, Package, ...
I don't see an option for "Worksheet".
UPDATE:
OK, I found that if I select "SQL File", a worksheet becomes available. Perhaps this is what you intended. However, when I issue the command
select col1 from my_table where row_id = 1;it still returns 0 instead of 1. Hmm, maybe my initial assumption was wrong -- if this is a second (e.g. different) session, should I expect the changes made in the first session in SQL Developer (the UPDATE command) WITHOUT a commit, to be observed in this second session? I thought that changes made in one session were not viewable in a different session until these changes are committed in the first session? If so, how to show this in SQL Developer? I must be missing something basic here.
Or, is SQL Developer issuing some sort of "auto-commit" without my knowledge?

How to open multiple Sessions in Solution Manager

Good Day Gurus,
I am currently working on Solman 7.1 Sp12.My question is :Is it possible to open multiple sessions in Solution Manager? Here is the scenario: The client is working on multiple incidents and instead of logging on to the system again to access the 2nd incident he would like to open another session within the current call he is working on.
Is this functionality possible in Solman? I have seen the functionality working before in CRM interaction center not sure if it applies in Solman.
Your help is highly appreciated.
Thanks

Hi Maria,
Options to Call a Function in an SAP System, by entering transaction codes in the command field, the transaction in bold is the one your want for opening multiple sessions.
You can use the F1 key on the command field to display the following possible entries:
/N to cancel the current transaction
/NXXXX to call transaction XXXX directly from another transaction. Without the prefix, you can only call XXXX from the SAP Easy Access screen.
/O to display the overview of the SAP GUI sessions on your computer
/OXXXX to call transaction XXXX in a new window directly from another transaction
/NEND to end the log on session with a confirmation dialog box
/NEX to end the log on session without a confirmation dialog box
/I to delete the window you are currently using
Regards,
Ruth
