Multiple Sessions

We recently upgraded to 10g R2 (10.1.2) from version 9.0.4. We are having issues trying to open a second window (or session). We get a "Server Not Responding" error. It doesn't happen all the time but doesn't seem as reliable as the previous version. Are there config settings I can modify to correct this?
Thanks, Phil

What's the OS platform of your Application Server ? What JRE version are you using and OS your client PC?
If you recently upgraded to 10.1.2 you should consider upgrading to 10.1.2.3 and applying the latest patches, see the following thread: Webutil File Transfer -Progress bar not being closed
Are you getting any FRM errors on the client side ?? Any dump files generated in the $ORACLE_HOME/forms/trace folder at the time of the error?

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 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 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.

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?

Abstract: ALLOW ABILITY TO LAUNCH TWO DISCOPLUS SESSIONS FROM SAME BROWSER CONNECTION PAGE
*** 07/17/08 07:31 am REQUEST TEXT ***
Please refer to bug 6656139. Need to get Discoverer Plus certified to
support launching two plus sessions from same browser connections page when
using SUN JRE 1.5/1.6 or higher.
As per bug 6656139 it appears to be JVM 1.5.x limitation, because same
actions work fine when using SUN JRE 1.4.2_xx.
*** 07/17/08 07:31 am BUSINESS NEED ***
Impossible to run reports against two different databases simultaniously
using same Discoverer instace, or just several reports at the same time,

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 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
Maria

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

Ruth

MacBook Pro do not read photo dvd recorded in multiple session in Windows

I have 20 photo dvds recorded in my pc in multiple sessions.
When I open the dvd using finder it only shows some of the folders not all of them. If I open the same dvd using parallels with windows xp it shows everything.
Is there any way that I can read the complete dvd?

Multiple session handling in the Web UI

Hi all,
According to the SAP help documentation, a user can have multiple sessions open in the Web UI. However after a certain period, inactive sessions are terminated. This is certainly the behaviour that we witness on our system, the second inactive session times out after about 25 minutes.
Does anyone know how to adjust the time out of this second session, this appears to be independent of the general timeout for htttp which is set at 2hours according to the transaction SMICM.
Thanks in advance
Paul

Follow the steps mentioned by Pankaj.
Even after this the debugger did not start, do the steps below so that HTTP debugger is on
1) Run the T-code SICF
2) Search for the service name CRM_UI_FRAME in the service name. click on F8
3) Select CRM_UI_FRAME and click on the Edit Menu. Select the option Debugging --> Activate Debugging
4) This opens a pop up, give your user name and click on OK.
Now start running the application. The debugger should start.
Hope this helps.

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).

Need to store multiple session values in flex

Hi,
I need to store multiple session values in flex based on the user who logged in.
For Example, if a user logged in as an administrator and in another windows another user logged in as guest, i need to maintain two seperate session for the two different users.
Is it possible for maintaining different sessions.
Expecting your valuable response.
Thanks
Jude Paul

Look at Shared Objects. You can store this information in them by creating a unique object for each type of user.

Multiple connections or multiple sessions preferred

Hi All,
Is it better to create multiple connections for each sender/receiver or single connection but multiple sessions for each sender/receiver? Assume in my case that there are about few hundred receivers. Thanks.

Edit : Sorry, bad answer.
