the recall of a message broker thread safety

Hi all:

I use a message broker called Solace (similar to Tibco in term of its APIs), but this issue applies to messages in general officers as well.

There is a XMLMessageListener #onReceive () callback method, which exports the requests from clients. The question is: when several applications at the same time, rush will be they queued to process? For example, #2 application will not enter the onReceive method until application #1 is transformed or discharged by a subtask?

It's the only way I can image how a message broker security threads in this scenario. Someone can correct me if I'm wrong?

Thanks, Johnny

Well, I do not know XMLMessageListener #onReceive (), but the jms MessageListener http://docs.oracle.com/javaee/5/api/javax/jms/MessageListener.html indicates the contract specifically thread in the javadoc:

"Each session must ensure that it transmits messages in series the listener."

If you use the API specific broker, however, the behavior is what specifies that the Broker application.

  • Cannot install the updates, receive error message: automatic updates has been disabled by the administrator, but I don't.

    Original title: How can I, as an administrator, turn on automatic updates, whenever I try, I get an error message saying that automatic updates has been disabled by the administrator.  I didn't do it, then?

    Question stands as is.

    Hello

     

    1. have you made any changes to the computer before the show?

    2. What antivirus application is installed on the computer?

    3. What are the different user accounts on the computer?

    This problem occurs if Windows Update has been disabled by one of the following settings:

    · Group Policy

    · System policy
    · Registry

    I suggest you follow these methods and check.

    Method 1: Perform the clean boot and try to install the updates.

    To do this, follow the steps in this link:

    http://support.Microsoft.com/kb/310353

    NOTE: Once you check the functionality, follow the suggestions under steps to configure Windows to use a Normal startup state.

     

    Method 2: Try to turn on the auto update by following the steps in the link below.

    How to configure automatic updates by using Group Policy or of registry settings

    http://support.Microsoft.com/kb/328010

    Registry warning: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base: 322756

    How to back up and restore the registry in Windows

     

    Method 3: Turn off the antivirus application and try to download the updates and check.

     

    Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

     

    Method 4: Perform a full scan of the computer using the following antivirus applications.

    Microsoft Safety Scanner: http://www.microsoft.com/security/scanner/en-us/default.aspx

    Malicious software removal tool: http://www.microsoft.com/security/pc-security/malware-removal.aspx

    Note: The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

     

    I hope this helps!

    4. start - devices and printers - add a printer - add a local printer - create a new port - local port and name it QBD_PDF.

    5. Choose install AMYUNI Technologies - Amyuni Document Converter 300 (click the button update windows if it is not on your list).

    6. If windows detects you already have a driver and then choose to replace the current driver. The printer name Quickbooks PDF Converter - do not share the printer - NOT set as the default printer. Finishing

    7. start right click - devices and printers - printer QB, choose printer - properties and go to the Advanced tab.

    8. remove the checkmarks in the 4 elements with square next to them (lower part of the screen) boxes, and then select "Print directly to the printer" press OK to close the window.

  • Is it possible to use a Type of personalized content for the REST service operation messages?

    I try to POST to the third party, documentum of EMC, REST service using service broker in 8.53 peopletools integration operations. Unfortunately, the third party only accepts a content type of 'application/vnd.emc.documentum+json', which I could not send PeopleSoft and use a message definition at the same time.

    In my service operation, if I do NOT fill the request message I can POST to the URI with the such custom content type defined in the property page of the connector in the routing. I have not found a way to do it and also present JSON content on demand, since there is no message associated with the operation. Is it possible to include in this type of message content without using a request message?

    If I DO not fill the request message I can't POST successfully because the message content-type of "application/json" gets passed as the content-type instead of the value in the property page of the connector from the routing. Is it possible to change the content type during the use of a message definition?

    Thank you

    Paul

    Hi Paul - you can turn on tracing by using the on demand connection as follows:

    1. on the routing set detail header and detail "journal".

    2. Main Menu > PeopleTools > Integration Broker > Service Operations Monitor > Administration > control installation Options

    -Enable logging of the bridge

    -On the registration of demand = 5 (to enable detailed logging)

    Note: On request connection only works for the outgoing synchronous Services. In this case, we should be fine. You will find the by transaction log file on your gateway web server... / applications/peoplesoft/PSIGW.war/WEB-INF/.

    I did it for one of the REST service operations my test (I'm on 8.52.22). I have my content type of message the value application/json to the operation of the service page. On the routing page, I added a connector property content-type=application/vnd.emc.documentum+json.

    Here are the results on the integration gateway logs:

    Message-ID:<-.................@nowhere>

    MIME-Version: 1.0

    Content-Type: multipart/related; Boundary = "Integration_Server_MIME_Boundary."

    Content-ID: PeopleSoft-internal-Mime-Message

    PeopleSoft-ToolsRelease: 8.52

    -Integration_Server_MIME_Boundary

    Content-Type: text/plain; Charset = UTF-8

    Content-Transfer-Encoding: 8 bit

    Content-ID: IBInfo

    Content-Disposition: inline

    Sync There ... * deleted for security purposes *... ContentSection0text/plainN

    CREATE5000000000000

    -Integration_Server_MIME_Boundary

    Content-Transfer-Encoding: 8 bit

    Content-ID: ContentSection0

    Content-Disposition: inline

    username = * collected for security purposes * & password = * deleted for security purposes *.

    -Integration_Server_MIME_Boundary-

    The Content-Type of the delivery is sent as HTTP Connector of the target and the content of the message (text/json) Type property is always persistent (see the text in bold above). You can compare logs between your two scenarios (with and without the message in the POST) and see if you find something interesting.

    I even tried the following code to see if that helps, but I get the same results.

    & MSG. IBInfo.LoadRESTHeaders ();

    / * Adds additional headers not defined on the route * /.

    REM & MSG. IBInfo.ConnectorOverride = True;

    bRet = & MSG. IBInfo.IBConnectorInfo.AddConnectorProperties ("Content-Type", "application/vnd.emc.documentum+json", % Httpentete);

    & RESP = IntBroker.SyncRequest % (&MSG);)

    I'm working on a similar project at this moment where I'm integrating perceptual Nolij Web RESTful API (Document Management System). I had to resort to using a http client base (common of apache) java instead of broker of integration because of the similar frustrations with REST (cookies are lost, unable to deal with raw binary data in a response message, etc.).

    Benefits: Java provides total flexibility.

    Cons: As we are bypassing framework Integration Broker, we need everything (error handlng, logging, etc.) do it ourselves.

  • PANIC in the recall of Vix_FindItems causing the crash

    I'm trying to use the VIX API to get a list of all virtual machines stored to a host computer. The easiest way to do this seemed to be to use Vix_FindItems and pass it a callback that was to build a chain of all VM file names (add at the end of a string, whenever the callback has been called). However, on the third iteration through the callback, the execution stops, displays an error message and exit:

    Panic: SAY d:/build/ob/bora-222403/bora/lib/sync/syncWaitQWin32.c:336

    The callback method that I wrote with debug printf (s), is the following:

    void VixCollectVMS(VixHandle jobHandle,
                         VixEventType eventType,
                         VixHandle moreEventInfo,
                         void *clientData)
    {
         int i = 0;
    
         VixError err = VIX_OK;
         char *url;
    
         printf("\nProcessing event...%d\n", eventType);
    
         //Only actually process item found events (8).
         if(VIX_EVENTTYPE_FIND_ITEM != eventType) {
              return;
         }
         printf("Checkpoint %d\n", ++i);
    
         //Get the location on disk
         err = Vix_GetProperties(moreEventInfo,
              VIX_PROPERTY_FOUND_ITEM_LOCATION,
              &url,
              VIX_PROPERTY_NONE);
    
         //This checkpoint never gets reached on the Panicked invocation of the callback
         printf("Checkpoint %d\n", ++i);
    
         //Assuming it's successful, append it, otherwise print the error
         if(VIX_OK == err){
    
              strcat((char*) clientData, url);
              strcat((char*) clientData, "\n");
    
         } else {
              printf("Error encountered: %s",
                   Vix_GetErrorText(err, NULL));
         }
         //Clean up
         Vix_FreeBuffer(url);
    
    }
    

    I spent in a char * calloc () ed 10000 characters like clientData, was expected to move from one point to another, so that I could just continue to add to it here. I also assume that the filenames of computer virtual channel would be made available for the function call after reminders were completed running, reported by putting a VixJob_Wait in the calling function. As it is, execution stops flawless during the third call of the recall.

    So, two questions: first, why is that happening and what means the error? The error seems to be related to me trying to use clientData for transmitting information, between and out of the callback function.

    Second, is there a better way to get a list of all virtual machines registered with a host?

    (Note: this is compiled under Windows, but apart from the change in the location of VIX.h in the header, should be easy to compile on Linux.)

    Its mem smash a bug in your configuration.

    VMNames = '\0 ';

    should be

    * VMNames = '\0 ';

    strcat() is very unhappy with the original.

    Is it possible to do it automatically, or I have to open all messages and add the addresses one by one?
    Thank you very much.

    As soon as, Thunderbird adds contacts not in your personal address book to an address book "collected addresses".

    Add all recipients of all messages in a single list.

    I don't know what that means. You want to create a new address book or a mailing list?

  • During the transmission of a message, it is surrounded of how red lines I elinmate them

    During the transmission of a message, it is still blocked with red lines around the message and title. I've never had this happen with other programs such as Windows Live Mail, hope you can help eliminate this very annoying problem.
    Thank you.

    Ignore them. They are the attempt of Thunderbird to help you navigate through complex systems of images, often resulting in multiple shipments. They allow you to decide exactly here where in a message you insert new. I sometimes try to flatten the content by removing unnecessary nested frames, but it is generally not worth the effort.

    Send a copy of this message to yourself and you will see that they are invisible to the recipient - until it is re-released in Thunderbird.

  • How to merge all my email accounts so that all messages appear in the pane of a message?

    With Outlook Express, messages from all accounts appeared in the part of my message. How to configure this in Thunderbird?

    There are 2 issues here:
    1. When you open an account in thunderbird, it opens new drafts deleted folders etc. for each account, and message filters only work for Auditors that they are defined in. Even if you select < view/unified > there is still a maze of folders for the account of another user in your navigation pane. If you don't want this, the only way I could work around was to create user accounts in windows live or outlook and import < import/tools/settings / >-laborious! * You must remove the accounts that you created manually in thunderbird < tools/accounts > until you import or those that you have already created is not replaced, and will always be separated. Result: you get ONE of each record, receiving the e-mail for all the accounts and a message filter installation! And user accounts still show UN user accounts, but not the folders navigation pane.

    2. If you don't want to do the above, you can try < view/unified >. There is also a favorite option. If so, you must configure your filters of message for LOCAL FILES unless you want them to run on a single account.

  • Why "Bulk Mail" foder not shows not the number of unread messages unless I click on the folder (via IMAP Yahoo mail)?

    'Spam' of the Yahoo e-mail account folder (as seen through the web interface 'Yahoo mail') is displayed in Thunderbird as 'Bulk Mail' (IMAP). Looking at the account in Thunderbird foders, I see the number of unread messages in each folder. "Bulk Mail" always seems to be empty. If I click on the "Bulk Mail" folder, then magically messages appear in the message list and the number of unread messages is displayed next to the name of the folder, as in all other folders for this account.

    Why I need to touch the "Bulk Mail" folder to see the number of messages inside?

    Yahoo deletes the messages in this folder during certain periods. I'm in danger of losing messages unless I remember to touch all of the mail files in bulk from my account Yahoo in Thunderbird.

    How do I get the "Bulk Mail" folder to display the number of unread messages as do all other folders of the same account?

    Thunderbird 24.6.0, Windows 7 Enterprise Edition (Sp1)

    Pekka

    I do not use IMAP in Thunderbird, so I can't provide instructions step by step, however, other e-mail programs have settings synchronize each individual file on a calendar or using push IMAP (vs when you click it) or not. If Thunderbird has these parameters, I would expect that they appear in the properties of the folder or the account settings. This might be useful, but I don't know if you already have a few dig like that or not.

    FYI, a quick search brought me to this page:
    https://support.Mozilla.org/en-us/KB/configuration-options-folders

    An item listed on this page is the following:

    Configure the IMAP folders, connections, and namespaces

    Location of the menu: tools | Accounts settings | < account name >. Server settings | Advanced

    It might be a good starting point because it does not mention connections to IMAP folder, but the folder properties could still be somewhere easier to read first, just in case. To do this, the site lists this:

    Configure the properties of the folder (IMAP folders only)

    Menu card: Edit | Folder properties. General information

    However, I think that you could right-click on the "Bulk Mail" folder and click Properties on the shortcut menu.
