Integrated Pipeline mode breaks my CF11, but isn't the Classic Mode

Hello

I encountered a problem, costs after migrating to IIS 8.5 (from IIS 6), CF 11.07 - ent.

What's a sense to the pros out there?

Here's what I see:
Taskman, as SOON as the bunch of JVM Max memory has been reached (for coldfusion.exe), CF will become partially or totally insensitive.

I understand about connector tuning, and is not the problem here. Here are the lines of log isapi_redirect:

----------------
This first line below is the LAST line in the log have to do with connections (as you can see, I'm away from maxing out. Also, my file server.xml MaxThreads and Timeout are set to 1600 and 60000 and I use it only a wsconfig / x and one application pool, for a total of 1600 connections. I was very stable with those same numbers in IIS6)

[1532:3796] [info] ajp_process_callback::jk_ajp_common.c (2244): number of reuse current (cfusion) is 91 connection re-use max 800 and total number of endpoint 1600

error condition then hits

[1532:3796] [info] jk_open_socket::jk_connect.c (817): connect to 127.0.0.1:8014 failed (errno = 61)
[1532:3796] [info] ajp_connect_to_endpoint::jk_ajp_common.c (1127): (cfusion) failure opening socket (127.0.0.1:8014) (errno = 61)
ajp_send_request::jk_ajp_common.c [1532:3796] [error] (1787): failed to connect to the back-end (cfusion). Tomcat is probably not started or is listening on the port incorrect (errno = 61)
[1532:3796] [info] ajp_service::jk_ajp_common.c (2903): request to send (cfusion) Tomcat failed (recoverable), due to the error when sending the request (try = 2)
[1532:3796] [error] ajp_service::jk_ajp_common.c (2924): (cfusion) connects to tomcat failed (rc =-3, errors = 178, client_errors = 478).
[1532:3796] [error] HttpExtensionProc::jk_isapi_plugin.c (2763): service () failed with http 503 error


(I also sometimes see the following too)
[1532:14080] [info] ajp_connection_tcp_get_message::jk_ajp_common.c (1401): (cfusion) cannot receive the message header response of tomcat, tomcat (127.0.0.1:8014) forced a close connection for socket 5684
[1532:14080] [error] ajp_get_reply::jk_ajp_common.c (2376): (cfusion) Tomcat has failed or refuses the connection. No response has been sent to the customer (yet)

Once the error condition starts, then these error lines much repeat several times (with different thread... number IE [1532:xxxxx] where 1532 is the PID for the IIS for application pool worker process I am).
----------------------
CF then either freezes, or sometimes comes back to its own (maybe 20-30 minutes more later) and the isapi_redirect.log resumed normal activity (no more errno = 61) logging.

----------------------
Can I disable the integrated Pipeline mode (which makes classic), reset, and the problem goes away.

I'm a pure shop CF, no .NET or. ASP, CF just and static HTML on my IIS. I don't have a built-in mode. But since I read on google that Jakarta/CF is 'supposed' to play with Mode integrated nice, I am very concerned that my problem is a Canary in a coal mine, as it triggers the right when Max JVM is reached (!) which should have nothing to do with that because it is just engaged, not used, memory, right? It makes no sense to me.

My summary index: CF instability/grip are triggered right when bunch JVM MAX is reached (as shown in taskman for coldfusion.exe), AND I use the Integrated Pipeline Mode instead of the classic mode. (Connector a bad update is not involved in this situation).

Opinions?
Thank you!

Welcome to Byron,

Thanks for the reminder - check level CF update and if corresponding isapi_redirect.dll is applied.

Lets say I find the details in isapi_redirect.log 'CF tomcat business secret', which are not well documented anywhere. Sometimes the content of the newspaper lack useful details or periods of information when you know its use occurs. Web research certainly seems to provide a lot of queues to tomcat tuning this product or this message given. What I note - when the CF Java part is down or having a problem

the ISAPI log is more verbose.

If you want to watch the Java CF memory use issues and GC you may well do to activate JMX with JMC (JDK Java mission control tool, suggest version 5.4 and above JDK 1.8u45 or higher). Why so much? It's free ($) and you get to see not only bunch, bunch no but what tomcat is doing as well.

JMC, FOR EXAMPLE:

Cordially, Carl.

  • My integrated Webcam is recognized by MAX but not as the IMAQ device

    Hello

    I use with 2014 LabVIEW IMAQ 14 and IMAQdx14.

    I am able to use my webcame MAX both in the Vision Assistant, but when I am trying to generate vi, in the wizard, IEEE1394 Imaging is grayed out.

    When I am using triggered image acquisition and select cam0 as the name of the interface (name of my camera to the MAX), I get the error code:-1074397163 (NOR-IMAQ: the session or the interface passed is not valid.)

    In MAX, I can see and use my camera, but it appears directly in the devices and Interfaces (and not under devices NOR-IMAQ)

    I can't find out if it is compatible live show... Is this to say that my camera is not supported by IMAQ? Is there a way to check whether LabVIEW?

    Thank you

    Karol

    Hi Karol,

    Since you are able to use the camera in MAX, it is DirectShow compatible. The reason why you get this error, it is that your device is not compatible with the IMAQ driver. Instead, you should be using the driver IMAQdx and corresponding IMAQdx live. Once you use those, you should be able to control in LabVIEW. It isn't an IEEE 1394 device either, so I think that it is expected that all options for this would be grayed out. Hopefully that should get you going in the right direction, but please post again if you have problems with the generation of VI you.

    Thank you

    I tried to go to Web sites that I visit every day and they are all blocked by a virus that seems to be Mozilla (but isn't) and watch the logo of mozilla and says my site has been blocked by the parent control of Mozilla and you must sign up for this. He asks that all the personal information you give NEVER online so I knew it was a virus. I write this in safe mode. My Vipre will not pick up this virus and Malware bites either. I have deleated Mozilla and reinstalled but it did not work.

    You can attach a screenshot?

    Use a type of compressed as PNG or JPG image to save the screenshot.

    Do a check with some malware malware, analysis of programs on the Windows computer.

    You need to scan with all programs, because each program detects a different malicious program.

    Make sure that you update each program to get the latest version of their databases before scanning.

    Alternatively, you can write a check for an infection rootkit TDSSKiller.

    Hello

    I know that it isn't the best article at the post office, but there is no instance void for my computer (Satellite NB10T) series and this problem is bound to win 8
    I'm stuck at the moment: I disentailed 8 victory because I want to go back to 7

    I am aware of
    http://APS2.toshiba-tro.de/KB0/TSB2C03F80002R01.htm
    The problem is that I did not mode Boot under advanced system configuration option; the only thing I can do is enable or disable secure under the Security tab, startup mode which isn't enough

    I also added a supervisor password. It adds a clear keys for secure boot option, but still nothing on the Advanced tab to move to the Csm.
    Clearing keys does not work too.

    I tried to boot multiple linux distro and win7 on usb bootable (theses work on other computers), but no luck. Boot order usb first value of course).
    What can I do?

    Edit: will put some pictures of the uefi

    You posted the screenshots of the configuration of Toshiba utility.
    The boot mode must be changed in the BIOS settings.

    To access the BIOS of the laptop must be turned off.
    Then put the unit BUTTON and press F2 to enter the BIOS.

    In the BIOS, you will find the necessary options: secure boot must be disabled and the UEFI mode must be changed to MSC mode

    If you want to reformat the hard disk, in erasing all data on the computer, there is no need to uninstall.  Deactivation is sufficient.

  • Happy Integration Suite: Mode of Stand Alone Server: authentication

    I'm just started to try to understand and the CIS. The question I'm trying to answer is: why when trying to initialize the CIS, we do not credentials. I looked at the example and CheckInFile.java for example, I do not see a routine that asks the customer to identify or authenticate.

    I see that in the SIS API, the client must connect / authenticate but not in the CIS. What did I miss?

    Thank you!

    Hello

    You will not miss anything, it's actually a really cool feature. Default WHAT CIS connects to your content server, much the same way that the web server is on port 4444. When you live like that, you can ignore the authentication and just get a username. The content server must be pre-configured, but to allow a connection from the server you use CIS, although. You probably run it local on the same machine the server content, so you do not encounter any questions, but if you you connect from a remote server is ip must be included in the security filter in the config.cfg file server ip. CIS can be configured to connect to the web server rather than on the content server case you need credentials.

  • I have just refrehed Firefox, but have lost the upper left menu which had 'Bookmarks' 'tools' etc. Can you please tell me how to get that back?

    I have just updated Firefox, but seems to have lost the menu on top left of the page (very useful) who had a number of elements, including the 'bookmarks', 'tools' etc.. On the far left of this 4/5 menu item is the logo of Mozilla.

    Can you please tell me how to get it back?

    Hi Peter, to activate different bars on and outside, including the Menu bar, you can use one of the following methods to view the list of the toolbar, and then select the desired bar (s) there:

    To activate the menu bar, toolbar bookmarks or other bars, click it in the list.

    Is - that you are looking for?

    If something isn't quite right, it is possible that an extension has been tweaking the menu/toolbar area...

  • Firefox used to give me a menu when I saved a bookmark - where to drop them, etc. ; now he saves (I think), but just in the list of bookmarks without end. That's happened?

    I do a due diligence and requested knowledge base, but I confess that I didn't search too long. Two or three updates there, I was able to save bookmarks and a small menu (I mean menu drop down, but not) appear asking for tags, the precise positioning of the new bookmark and for me to change the name. I don't know who has not been deleted, then why isn't the little menu appear?

    In addition, the answer I found said click on the star, which blue auto; clicking again brings up the menu. Only, this isn't.

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of your modules is causing your problem (switch to the DEFAULT theme: Tools > Modules > themes).

  • need to repair the startup of windows, files, but cannot use the cd-rom drive

    for the past 6 months that I had to use a return to the top of the boot disk to get windows to load so I could copy all my important files and documents on DVDs as my windows xp edition home sp3 OS suddenly stopped wanting to load normally and I'd just reformat the HD

    Last week... my browser froze causing me to have to stop by turning off the power button... to restarting my pc, my cd-rom drive is not found and now I am unable to finish to copy my important files and these DVD

    is there anyway I can repair windows without using the cd-rom drive... .. I can get in the F12 boot menu but not in the installer of F2 or F8 safe mode without using a cd-rom drive to launch the boot disk

    2.2 under Win XP home edition sp3 dell xps 210 system, intel duo core processor 4 GB ram and 500 GB HD

    It has only 1 CD/dvd-rom combo drive and 4 smaller slots for memory cards and other... I have 3 slots open usb but do not have the files of windows to a flash drive recovery

    would it be possible to make a recovery file or file on a USB stick the size of a flash drive and boot would need... currently the largest one I have is 4 GB

    Hi storm36,

    You must have the Windows XP disk to repair Windows. As the CD/DVD drive is not getting detected, we recommend you try the following steps and check the result.

    Step 1: Check if the device is detected in the BIOS (basic input/output device)
    a. start your computer and press on delete key continuously to see the BIOS.
    b. check if the CD/DVD device is detected.
    c. If this isn't the case, then unplug the unit and he reconnected inside the CPU/Tower.
    d. check the result.

    Step 2: If the device is detected in the BIOS, try the following steps:
    a. start your computer and boot to the desktop.
    b. Click Start, click Run, type devmgmt.msc, and then click ok.
    c. select my computer, click the Action menu and click scan for hardware changes.
    d. check if the CD/DVD device is listed in the list.

    Step 3: If the problem persists, restore the computer
    see How to restore Windows XP to a previous state .
    b. Once you have restored the computer, check if the CD/DVD drive is visible.
