Session manager attach data

I've got a successful implementation where I am using NI's Session Manager to manage instrument sessions. I want to be able to attach information to the session to reference later. I have managed to implement the AttachLong and AttachString methods (as well as the get versions) and things are working just fine. However, I can't seem to manage to get the AttachObject method to work out.
Does anyone have any sample LabVIEW code for implementing the IInstrSession.AttachObject / IInstrSession.GetObject methods?
Thanks

hi,
1.check to No the cache
2.check at what level you have set the user (max is 7)
3.clear all cache and the logs.
4.restart all services...
reults???
is it possible to show us the results???
hope i helped....

I have a problem with session manager session files because of the invalid json storage data submited by firefox

Hi, i have problem with session manager's session files. The problem is: the submitted storage data from firefox which is put between "storage":{ and its matching closing brace } But in some of my session files there is non equal { and } under storage's braces. I need to get storage data but in my case it is very hard to do. My question is there any char put before or after { and } like /{ or \{ to avoid confusion? If there is not such thing, i think there could be different solution but i am not sure: i look couple of my session files; after "storage":{...} there is ,_"formDataSaved" so i can get storage data in this example ... by looking between "storage":{ and ,"_formDataSaved" easily. Is there every time ,"_formDataSaved" after "storage":{ ? Thank you.

Well, it seems waiting is not my strong suit..! I renamed a javascript file called recovery to sessionstore. This file was in the folder sessionstore-backups I had copied from mozilla 3 days ago, when my tabs were still in place. I replaced the sessionstore in mozilla's default folder with the renamed file and then started mozilla. And the tabs reappeared as they were 3 days ago!
So there goes the tab problem. But again when I started mozilla the window saying "a script has stopped responding" appeared, this time the script being: chrome//browser/contenttabbrowser.xml2542
If someone knows how to fix this and make firefox launch normally, please reply! Thank you

How to import old Session Manager data

I just upgraded to Firefox 35.0 and had to reinstall Session Manager. Now Session Manager doesn't show any of the old saved sessions. I've found the file containing these old sessions, but can't figure out how to import that file so that I can use it with the new versions of Firefox and Session Manager.

#Go to your profile folder:
#*[https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data#w_how-do-i-find-my-profile Find you profile]
#Exit Firefox.
#Look for sessions folder, enter in it and put here that file with old sessions.
#Restart Firefox and try load the session.

Non Blocking Socket ans Session management

All samples of Non Blocking socket use SelectionKey.attach( Object ob) to attach a partial message if the received data is incomplete. So far so good.
Are we supposed to use the same approach for session management ( Keeping info on Username, password, timeout values, etc.)
Thanks

I disagree with your first statement. The attachment is normally a session object that contains user information, session state, and the ByteBuffer.

What is new with MAX 2.0 and is it compatible with Session Manager?

We added non-IVI instrument information in, basically the same structure as for IVI instruments,
into the ivi.ini file to keep all instrument information in the same place. Using MAX Version 1.1 caused no problems whatsoever and the system worked fine. With the advent of MAX 2.0 you seem to use ivi.ini as well as config.mxs to store instrument information. What we have found now is that given a working ivi.ini file from MAX 1.1, we end up with 2 or 3 copies of all the devices in the IVI Instruments->Devices section! When the duplicate entries are deleted and the application exited, the
ivi.ini file is updated minus the [Hardware->] sections which contain the resource descriptors that our appl
ications look for. As an added complication, under MAX 2.1 (From an evaluation of the Switch Executive) It behaves the same, except that it almost always crashes with one of the following errors. 'OLEChannelWnd Fatal Error', or 'Error#26 window.cpp line 10028 Labview Version 6.0.2' Once opened and closed MAX 2.1 will not open again! (Note we do not have LabVIEW on the system.) What is the relationship between the config.mxs and ivi.ini now? Also, your Session Manager application (for use with TestStand) extracts information from ivi.ini and may expect entries to be manually entered into ivi.ini (e.g. NISessionManager_Reset = True) i.e. Is the TestStand Session Manager compatible with MAX 2.0?

Brian,
The primary difference between MAX 1.1 and 2.x is that there is a new internal architecture. MAX 2.x synchronizes data between the config.mxs and the ivi.ini. The reason you're having trouble is that user-editing of the ivi.ini file is not supported with MAX 2.x.
Some better solutions to accomplish what you want:
1. Do as Mark Ireton suggested in his answer
2. Use the IVI Run-Time Configuration functions. They will allow you to dynamically configure your Logical Names, Virtual Instruments, Instrument Drivers, and Devices. You can then use your own format for storing and retrieving that information, and use the relevant pieces for each execution. You can find information on these functions in the IVI CVI Help file located in Start >> National I
nstruments >> IVI Driver Toolset folder. Go to the chapter on Run-time Initialization Configuration.
I strongly suggest #2, because those functions will continue to be supported in the future, while other mechanisms may not be.

Session management in Info View with two different logins using single sign

There is a form with 2 user logins UserA and User B to redirect to infoview with sso in my application. I am able to go to each of the Infoview pages successfully but have the following problem.
User A logs in and infoview opens in a new IE window and sees his/her folders based on permissions and is able to do his/her work for the first time.
User B logs in andand infoview opens in a new IE window sees his/her folders based on permissions and is able to do his/her work for the first time.
After a while when User A tries to access the InfoView in the previously opened IE Window, he/she gets an error message. An error has occurred: The object with ID 2519 does not exist in the CMS or you don't have the right to access it.
User B is able to continue his/her work. Who ever logs in the last, he/she is able to continue his/her work but the other one gets an error.
Please let me know on how to address this issue . I added logonToken and tried everything at my hand but no success. Is this session controlled by business objects or by the jsp page. What more changes are required for my jsp page to fix the error. Attached below are the form and the applogon.jsp snippets.

Active sessions showing no data in pie-chart

Hi All,
Does anyone know why my Enterprise Manager cosole in Oracle 10g installed on windows xp professional is not showing any data? Availabilty is always 0% for the instance ORCL and the active sessions pie-chart is always showing 0.01 since May 17,2005.
Can anyone tell me how to configure EM so that instance ORCL and the active sessions start showing data again?
Thanks

Session Manager not thread safe

We are running 6.0 web server with IWSSessionManager turned on. We have the failover set to true so that we always load from the persistent store.
We had a situation where a frame set invoked 2 requests to the application. The logic in the session manager seems to be for each request:
1) the session is loaded from the database.
2) the new session overwrites the session in memory.
3) the servlet/jsp uses that session.
4) that session is persisted.
Now.. if only one of the requests actually modifies the session then threadA and threadB have 2 session instances which have unique objects with the same session id. The last one to complete is stored in the database. This would result in data loss. (btw.. the code in question is IWSSessionManager.getSession(String id, ServletContext context)).
Has anyone else seen this, or have we set up something really wacky?
Thanks!

Why did I lose Session Manager, as well as all my DOZENS of saved sessions (online course placemarks etc) with the upgr to 17? NEVER an issue, using FF forever

After installing latest ff (17.0) session manager was no longer installed. re-installed, but all previous sessions (as I stated dozens, with placemarks where I left off with online courses, pages with possible Christmas shopping items, etc etc) are ALL GONE. Been using FF for at least 10 years and this never happened before. Not a happy open source camper :(

Are you still using that profile where your extensions were installed?

Database session management in APEX

How is the database session managed in APEX? I found that sometimes a database session can last from page to pages in an APEX application, but sometimes every page starts a new database session.
Is there a way to control the database session in APEX?
Thanks,
-Fengting

Since HTTP is a stateless and connectionless protocol, you are not guaranteed to get the same database session between pages. APEX maintains the session state implicitly. Each session is assigned a unique identifier with APEX. The APEX engine uses the session ID to store and retrieve the applications working set of data or session state before and after each page view.
The session information persists in the database until purged. Therefore, as long as the client's session cookie has not expired, a user can continue running the application long after having first launched it. This is also what allows a user to run multiple instances of an application simultaneously in different browser sessions.
That being said, I think the answer to your question is that it is not necessarily going to be the same database session (but could be), nor can you control it. You should use session state.

Is it possible to use run-time configuration in conjunction with Session Manager?

I'm trying to avoid using MAX, basically because it's a pain for users to configure MAX when the application already knows what the configuration is. I actually get the configuration from a database, but that's another story. I've experimented with run-time configuration (see page 4-31 of the 'IVI Driver Toolset' manual) and it works fine. However, when I try to use this in conjunction with Session Manager, session manager complains that my logical name is not a driver session name. I suspect that Session Manager is looking up logical names from a different source, therefore run-time configuration won't work. Any suggestions? I've attached the files I'm working with.

SessionMgrTrial.zip ‏41 KB

Hello Mark:
The Session Manager GetLogicalNames method does not distiguish between logical names and virtual instrument names. A user of the method cannot ask for just logical names or just virtual instrument names. Right now you always get both. The new function is called InstrSessionMgr.GetNames. Notice that the online help file says Boolean for the flags parameter when it is an enum.
Hope this helps. If you have any further queries, please let us know.

Why not construct an intermediate page after the
login page that has SESSION_UNSPECIFIED and
a refresh META tag. The page can then refresh
to either the login failed or login succeeded pages
depending on how the login went! Looks like...
1) Login page (SESSION_UNSPECIFIED)
2A) Refresh page (SESSION_UNSPECIFIED)
< HTML >
< HEAD >
< META http-equiv="refresh"
content="0;URL=<a href=
"http://www.blah.com/forte.cgi?PageName=3">http://www.blah.com/forte.cgi?PageName=3</a>" >
< /HEAD >
< BODY >
Login succeeded. Please wait...
< /BODY >
< /HTML >
2B) Refresh page (SESSION_UNSPECIFIED)
< HTML >
< BODY >
Login failed.
< /BODY >
< /HTML >
3) We're finally in. (SESSION_REQUIRED)
I'm not sure if this works on internet exploder.

Subject: (forte-users) Session management for page builder
Hi everybody,
We have a lot of legacy code making use of the page builder service to
produce web pages. These pages were originally written without session
management. I'm now busy adding session management to them, but there is
one problem with this approach and I will appreciate if someone can shed
some light on it. Here it is:
Page one is submitted.
Some validation (authentication) takes place and depending on the outcome,
either page 2A (SESSION_REQUIRED) or 2B (error page with
SESSION_UNSPECIFIED) must be displayed. In order to implement this, I
needed a place to make a decision. The way I've done it, is to pass a
'virtual page' (SESSION_UNSPECIFIED) to the page builder service. The
validation is done here and request.PageName is then replaced with the
PageName of pages 2A or 2B. The HandleRequest() method is then called
again. The problem is that the ValidateSession() method does not get
invoked again, thus allowing 2A through without a session. How do I make
sure that the ValidateSession() method get invoked again?
The approach making use of templates look to me as if it has all the means
to do this (redirect tag), but I don't want to rewrite everything if I
don't have to. Is there a way that a pagebuilder page can be specified by
the redirect tag? This will definitely help, but so far I've only managed
to call templates from the redirect tag.
Is the template approach better suited for session management? It is
definetely better documented...
Regards.
Jaco

Handle task attachment data

Hello all,
I've defined a user task which returns, when completed, some XML data placed in attachment node. However I'm not able to handle such data from BPEL process, no mather what XPath expresion I use.
For example: if returned task has the following content:
<task>
<attachment><node><child>somedata</child><anotherchild>somedata</anotherchild></node>
</attachment>
</task>
¿What XPath expression should I use to extract content of <child> element?
Thanks.

Thanks Mike,
I was adding xml stuff into attachment data as a java.lang.String, I also solved this problem by using org.w3c.dom.Document instead. When the attachment is included as org.w3c.dom.Document object, BPEL process manager is able to browse the xml data with XPath.
Bye.

Cannot attach data store shared-memory segment using JDBC (TT0837) 11.2.1.5

Not enough storage is available to process this command.
If I'm wrong I'm happy to be corrected. If you reduce the PermSize and TempSize of the datastore (just as a test) does this allow JBOSS to load it?
You don't say whether this is 32bit or 64bit Windows. If it's the former, the following information may be helpful.
"Windows manages virtual memory differently than all other OSes. The way Windows sets up memory for DLLs guarantees that the virtual address space of each process is badly fragmented. Other OSes avoid this by densely packing shared libraries.
A TimesTen database is represented as a single contiguous shared segment. So for an application to connect to a database of size n, there must be n bytes of unused contiguous virtual memory in the application's process. Because of the way Windows manages DLLs this is sometimes challenging. You can easily get into a situation where simple applications that use few DLLs (such as ttIsql) can access a database fine, but complicated apps that use many DLLs can not.
As a practical matter this means that TimesTen direct-mode in Windows 32-bit is challenging to use for those with complex applications. For large C/C++ applications one can usually "rebase" DLLs to reduce fragmentation. But for Java based applications this is more challenging.
You can use tools like the free "Process Explorer" to see the used address ranges in your process.
Naturally, 64-bit Windows basically resolves these issues by providing a dramatically larger set of addresses."
