NOR-IMAQ: The interface passed or the session is invalid

• NOR-IMAQ: The transmitted session or the interface is not valid, why?

  Hello:

  I am facing an error that I can't explain. I configured a NI 1742 smart camera, to do some tests. The camera is configured in Max Max I can make some shots of the image and image captures without problem, I can do the same thing in the Vision Assistant. However, in LabVIEW I can't even start a session IMAQ.

  

  When I try to log in with the Vi Init IMAQ, I always get an error that says "NI-IMAQ: the transmitted session or the interface is not valid. I don't understand why this is happening. I did some research and found that this error indicates when the specified interface does not exist or the unit is unplugged. But I checked and rechecked, and as you can see in the previous image, the interface exists, and of course the smart camera is connected and working. No error status displays the status doesn't lead. I tried with the VI generated with the Vision Assistant, but had no luck, in LabVIEW always manifest error.

  

  

  I have LabVIEW 8.6, Vision Assistant 8.6, OR-IMAQ 4.3, MAX 4.6.1

  No idea why this error?, I tried, but I can't understand why!

  I really appreciate help. I'm a bit desperate.

  Thanks in advance.

  Robst.

  Hello

  Just to make sure, you run LabVIEW RT? and if you are, you are your VI running on my computer or have you create a project and added to your target of the smart camera and the VI under this goal?

  If you use your VI on your local computer, the error message makes sense because there is no img0 interface in your computer.

• Expiring sessions / are invalidated too early

  Hi all

  We have recently updated Apex 5.0.1 bug tracking application. Since then users complain to pass that their session expired error message and need to re-login, although they work constantly with the application and have not been idle. The behavior is not reproducible on demand. The application property 'Session duration in seconds Maximum' is set to dry 28800 (8 hrs), "Maximum Session Idle Time in Seconds" is set to 10800 seconds (3 hours). Neither value is reached, the problem sometimes happens also after working with the app for a few minutes only. The authorization scheme used by the application is set to "Invalid Session name of the procedure" pointing to a procedure that doesn't include that of:

  procedure invalid_session_proc is

  Start

  (wwv_flow). Show

  p_flow_id = > v ('APP_ID').

  p_flow_step_id = > 'LOGIN '.

  );

  apex_application.stop_apex_engine ();

  end invalid_session_proc;

  If the user simply is redirected to the login page.

  Questioning apex_050000.apex_workspace_activity_log I found two types of entries:

  
  

  one)

  ERROR_MESSAGE ERROR_ON_COMPONENT_TYPE ERROR_ON_COMPONENT_NAME APEX_USER

  person is ORA-20987: APEX - your session has expired - contact the administrator of the application.    WWV_FLOW_SECURITY FINAL_EXCEPTION_HANDLER

  APEX_USER is sometimes even vacuum!

  and

  (b)

  ERROR_MESSAGE ERROR_ON_COMPONENT_TYPE ERROR_ON_COMPONENT_NAME APEX_USER

  [email protected] ORA-20987: APEX - your session has expired - click < a href = "f? "p = 109:1:NO:" > here < /a > to create a new session.    WWV_FLOW_SECURITY FINAL_EXCEPTION_HANDLER

  I guess b type entries are created during a timeout values is reached, but why don't Apex sometimes think that the sessions are invalid / expired, even if they are still valid and product entries of type has?

  Someone has any advice on how to better analyze this problem? Because it cannot be replicated on demand, preferably a mechanism of the Protocol would be necessary which can be analyzed for example every day.

  No one can describe the algorithm that apex is used to determine that a session is valid or point to the documentation?

  Some setup information:

  * Apex version: 5.0.1.00.06

  * DB version: 11.2.0.3.0

  * Version of ADR: 2.0.10.289.08.11

  * Version of the glassfish server: 3.1.2.2 (generation 5)

  Any help will be greatly appreciated.

  Kind regards

  Christof

  Solution: the problem was caused by the browser asking favicon.ico when you open a file in a new browser window/tab instead of download. In our production environment, we use an Apache Web server as a frontend for Glassfish. In the Apache conf files a rewriting rule has been defined that redirect each attempt to a file in the root of the document to the login page of our Apex application. This of course also applied to favicon.ico, then all requests for this file invalidated the session of the Apex. After changing the configuration so that redirected requests for favicon.ico is no longer the problem disappeared.

• NOR-IMAQ library for the 64 bit version does exist?

  I use PCIe-1429 and NOR-IMAQ 4.1 and programming on VS2005.

  NOR-IMAQ library for the 64 bit version does exist?

  Wooddoll,

  In general, 64-bit import libraries are installed in C:\Program Files (x 86) \National Instruments\Shared\ExternalCompilerSupport\C\Lib64\MSVC\imaq.lib for 64-bit variants.

• With the help of NOR-IMAQ imgSnap (ANSI C) with Windows 7 x 64

  Hello

  I am trying to make a few acquisition base image using ANSI C to NOR-IMAQ calls (as distributed by the release of November 2009 Vision of OR). I develop on Windows 7 x 64.

  The Installer seems to work very well, but when I do the following call:

  void * theTempBuffer = NULL;

  Int32 theRetVal = imgSnap (mSession, & theTempBuffer);

  I get the following error:

  This 32-bit device works on a 64-bit with more than 3 GB of memory OS physics. This configuration could allocate memory 64-bit that is not supported by the device. To resolve this issue, reduce the amount of physical memory in the system.

  I see that I compile to a target 32-bit or 64-bit. I would have concluded that the PCI-1422, quite simply, is not supported under Windows 7 x 64, but the card (and attached camera) work very well for smacking or grabbing of images when I go to the Measurement & Automation Explorer.

  Thanks for your help.

  Eric, that did the trick. Thank you very much!

• NOR-488: The non-existent GPIB interface. During the generation of the Application in LV8.5

• Failed to set the specified property while the session is running - 6552

  I created a program to run several different scripts.  The first time through my program works perfectly.  The second time through (without reset of the card, or re - download vectors etc.) but it fails.

  As he tried to run the following command:

  niHSDIO_ConfigureDataVoltageCustomLevels (DIO3_acq_session, 11-13, 18, 19', 1.8, 2.0)

  I have the following error:

  "Specified property cannot set while the session is running.
  Set the property before the opening of the session, or abandon the session before setting the property. »

  Any suggestions on what could happen?  Alternatively, any advice for troubleshooting techniques to learn more about the problem?

  I found my error:

  Several of my scripts include a list of markers so that the records are captured, and I download the recordings captured later.  Whenever I'm about to run a script that has files, I made the "niHSDIO_ConfigureAcquisitionSize" function in order to identify the size and quantity of records.

  However, the first script in my program that I run I don't need records captured, so I didn't bother to call the function "niHSDIO_ConfigureAcquisitionSize".

  So, first map like the default setting for the number of records for the first script (in which I do not bother with all the captured records), but then the subsequent pass in my stream of test cards do not like the fact that I have had set up for many more records that he caught (lack of markers / triggers).

  It's a little confusing to explain, but I found the problem, so any help is needed.

• It has no option in Vision Assistant block to close the session classification! (How to fix 1074396030 error?)

  I use Vision Acquisition blok, then assistant block vision.

  These blocks are in while loop.

  Once the vision outputs help block class for the next iteration:

  ERROR: There are too many sessions open classification. You must close a session before you can open another.

  I know there are block to eliminate the classifier, but do not know where to connect!

  The only option you have without upgrading is to right click on the Express VI and select 'open the front panel. The Express VI then passes to a standard Sub - VI that you can edit and modify the code to close the session if needed.

  The disadvantage of this approach is that by doing this, we have broken the link between the Express VI and the Vision Assistant, which means that you can not change the algorithm developed in the Vision Assistant more you.

• -1074130544 the session handle is not valid.

  I'm using LabView 2011 on Win7.

  I'm working my way through the part of the "verification Procedure" of the "NI PXI-4071 calibration procedure.  Step 3 of the "Call the niDMM Reset VI." verification procedure and display Figure 1. The device, the NI PXI-4071, OK appears in NEITHER-MAX (Figure 2) and works well with the program 'NOR DMM Soft Front Panel'. When I run what I think is the correct code, the error 1074130544, "the session handle is not valid." appears. The BD and FP are shown in Figure 3.

  Hi Ed,

  If you want to call niDMM Reset, you will need to provide a descriptor of instrument rather than a descriptor of instrument.

  To start a session to your DMM and generate a handle of the instrument that you can use with other functions OR DMM, you must first call niDMM to initialize or niDMM initialize with Options.  You can wire the 'Dev1' to pin 'Descriptor of Instrument' and the function returns a handle of the instrument.  You can then wire the "instrument handle" PIN to pin "handle of the instrument" on the Reset niDMM VI.  Whenever you initialize a session to an instrument, it is also to close the session by plugging in the handle of the instrument to a function niDMM close .  The code snippet below shows what I described:

  

  I have also included a Simple VI of error handler to report all errors that occur.

  In addition, it seems that if you call niDMM reset with the default values instead of niDMM reset.  If you have not assigned any of the default values user defined logical name calls then both of your device should be functionally equivalent.

  If you make these changes, you should no longer generate the error.

  Good luck!

• The session is disconnected

  Is there a way to set the timer for the disconnection of the Session in the collector configuration.

  Hello Bbcstone,

  Unfortunately at this time it doesn't have a way to change the timer logout to log on to the appliance EPSC web INTERFACE.  After a period of inactivity, the user interface will be you disconnect from the security session.   However, you can still log in again and see the status of any work already under way by going to the reports section of the CSPC UI.

• ISA550W: WAN redundancy is in charge of the session affinity?

  Hi, we are using the ISA550W WAN failover mode.

  I wonder if we switch to weighted, double-WAN mode is the session affinity is respected? In other words, if we have a PC on the internal network by using an external website, all the following connections will use the same WAN interface, or will be they possible be changing back and forth between WAN different interfaces depending on the load?

  I see no mention of this in the docs, so I am assuming that it is not supported.

  Thank you

  Neil

  Double-WAN mode weighted, a connection from a PC should continue using the same connection WAN for the destination of the original session was created for.  However, if the PC opens another session (i.e. a connection to another site), then this session should use the best connection, which could mean that he uses the WAN2.

• Order of port re-auth authentication and switch / stop of the session

  Hi all

  We are implementing an ISE (1,4) and met regarded questions on the agenda of the authentication and a stop of the session after posture in line. We got mab, dot1x as authentication order (priority of authentication is set to dot1x, mab). We have configured a reauthentication in the ports of the switch. Windows uses begging all-connect NAM (see 4.2) to dot1x and posture. During the re-authentication, either all-connecting NAM or switch does not start an eapol start and switch allows the session to the MAB, where - as when seen dot1x and mab authentication switch order generates eapol start. The switches are 3750 (15.0 (2) SE8).

  Any possibility we could force the switch/NAM agent sent an eapol start during re-auth?

  Regarding the posture, posture once conform for an endpoint (after dot1x authentication passes) following a judgment of the ISE manual session for an endpoint, switch creates a new session in ISE changes and switch the State of the unknown port to posture. Posture ise AC client still shows status of complaint of posture in the endpoint. It seems do not know about the stop of the session. During NAM endpoint agent session performs a re-auth component however posture remains unchanged "in line".

  Does anyone have experience this problem?.

  Thanks in advance.

• RECORDING OF THE SESSION OF ASA

  Hi all

  We need to capture the session information from ASAs used for VPN traffic. The requirement is pretty basic, but in particular, we need to capture information about entering any Connect VPN which will then be allowed to hairpin on the Internet. The minimum information we need to connect are the IP address of the Source of the connection of the VPN client, LAN IP and then allotted if the hairpining Internet address allocated public IP and finally the VPN user name. We use PRTG network monitor, but do not know if he will accept the session log files.

  Any ideas on how to achieve this?

  Thank you

  Hello

  To my knowledge you already send Syslogs to a server, then to connect building/disassembly for VPN users messages, you should see the VPN username inside (en).

  The Syslog ID are the usual connection building/disassembly IDS which are

  • 302013 (Build TCP)
  • 302014 (TCP disassembly)
  • 302015 (Build UDP)
  • 302016 (UDP disassembly)

  The TCP connections log message format is for example

  302013
  Error Message    %ASA-6-302013: Built {inbound|outbound} TCP connection_id for interface:real-address/real-port (mapped-address/mapped-port) [(idfw_user)] to interface:real-address/real-port (mapped-address/mapped-port) [(idfw_user)] [(user)] 
  
  302014
  Error Message    %ASA-6-302014: Teardown TCP connection id for interface:real-address/real-port [(idfw_user)] to interface:real-address/real-port [(idfw_user)] duration hh:mm:ss bytes bytes [reason] [(user)] 
  
  As you can see that they contain information about the 'user' (user name), "real address" (ip address, the client has received), 'address topographiee' (public ip to which the connection has been coordinated address) as well as the information where the user is connected.
  EDIT: You mentioned that you want to save the source address of actual VPN connection also? To do this, you will probably need to look for some other ID Syslog
  The actual information on the Syslog message ID can be found here

• Join the Session after 3rd party authentication OAuth

  I use 5 APEX and integrate my application with another 3rd party solution. This 3rd party solution uses OAuth2 for authentication, which has a static redirect_url (a successful authentication post) which cannot be defined in the URL to call. Rather, it is defined as part of their application.

  I know it's confusing, so here is the whole process that happens:

  • Web server is Node.js (Express with Passport for OAuth authentication) makes queries APEX proxies to ADR 3 / Tomcat.
  • The user connects to the application of the APEX and gets a new session ID.
    • ex: f? p = 100:1:20953642103077
  • Once logged in, there are a few JS on Page 1 (P1) that detects whether the user has been authenticated with this 3rd party service (call the 3PS for that matter). It does this by looking at a custom cookie that is set by the web server for Node.js (let's call this 3ps_token).
    • If 3ps_token is null, then it will trigger the process of 3PS OAuth and use is redirected to their site to connect and to grant the appropriate privileges.
    • Once 3PS has granted the privileges, the user will be redirected to a predefined URL which is stored as an attribute in the 3PS area. I can't pass in the URL as a parameter to URL redirection and don't have, so no real way to back the session APEX I was coming.
    • The redirect URL is currently going back to the Node.js, which sets the 3ps_token in a cookie, and then tries to redirect to the APEX and 'join' the existing session. This is where I'm having issues as the URL that I provided is/ords/f? p = 100 (as I don't know the original session).

  How can I join my existing session of APEX (in the example above, 20953642103077)? If the following solution here: login page of APEX 4.1 kills the existing session cookie but this would require a custom authentication which I was hoping to avoid. Christian Neumueller-Oracle made a comment at the bottom of its solution join session is not secure. Is their a best practice because this so?

  Hi Martin,

  I have good news for you, we implemented session to return to the APEX 5. It will allow you to have an APEX URLs without a session id. You must first enable this feature in the Administration of the proceedings (see https://docs.oracle.com/cd/E59726_01/doc.50/e39151/adm_wrkspc002.htm#BABJCGAG) and then at the page or application level. Please consider the implications of security in this article, because to return potentially open your application to XSS attacks from other applications on the same server.

  Kind regards
