What is the lock server

Hi,
I was setting up atg demo application "QuincyFunds" through CIM, while creating server instances, one option was asking to create instance as lockserver.
Can anybody please let me know what is that lockserver means.
Thanks,
gaurav agrawal

Hi,
I have gone through document provided in the link.
Below is my understanding, please correct If wrong:
Only one ServerLockManager configuration would be there across all the instances running for an application. For example, If we have10 instances comprised with 6 store site instances, 2 BCC and 2 CSC then only one instance should be configured as ServerLockManager and other 9 should be configured as ClientLockManager.
Main benefit of using that locking concept is to keep cache consistent on all server instances.
Thanks

  • How to find out what is the lock key for the computer

    How to find out what is the lock key for the computer?

    You don't.
    If you forgot or lost the password, all you can practically do is reset it.
    The manner in which you do so depends on what version of OS X you are running. The older versions utilize the reset password utility on your recovery/re-installation disk/drive.
    On Lion, you use the following technique to reset the Administrators password:
    Boot to your Lion Recovery Partition, by holding down the Option key while starting, and then selecting the Recovery HD as the boot choice.
    Once booted, at the top of the screen is a menu ..., select Utilities / Terminal from the menu bar.
    In the Terminal window, type “resetpassword” (without the quotes) and press return. A “Reset Password” window will open. Select your boot volume (your SSD drive) if it is not already selected. Select your administrators username from the menu labeled “Select the user account” if it is not already selected. Follow the prompts to reset the password. Restart the computer from the apple menu.

  • What are the lock modes in Lock object

    What are the lock modes in Lock object ?
    what are the divfferences between
    Exclusive , cumulative
    Shared
    Exclusive , not cumulative
    Could any body explain what happens in each table lock ?
    How the lock consists ?

    HI
    Lock objects are used to synchronize access to the same data by more than one program.
    The lock mode controls whether several users can access data records at the same time. The lock mode can be assigned separately for each table in the lock object. When the lock is set, the corresponding lock entry is stored in the lock table of the system for each table.
    There are three types of lock modes
    1.Exclusive
    2.Shared
    3.Exclusive not cummulative
    Exclusive lock: The locked data can only be displayed or edited by a single user. A request for another exclusive lock or for a shared lock is rejected.
    Shared lock: More than one user can access the locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock is rejected.
    Exclusive but not cumulative: Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. All other lock requests are rejected.

  • What is the windows server 2013 license version than I need to install workflow manager 1.0

    what is the windows server 2013 license version than I need to install workflow manager 1.0?
    enterprise or standard? can I install it on datacenter?
    please provide me with the reference.
    thanks

    Workflow Manager will work with either SharePoint Enterprise or Standard.  It doesn't work well with Foundations since it depends on User Profiles to pass user identity to the workflow.  And yes you can install it on Windows Server datacenter edition.
     Here are the supported platforms for installation
    http://msdn.microsoft.com/en-us/library/jj193487(v=azure.10).aspx
    This article talks about integration with SharePoint and states that Foundation is not supported, but it doesn't differentiate between the Server editions, so any edition will do.

  • What's the "web server" in WAS... ?

    A non-SAP colleague of mine bugs me with questions like "what is the web server-part of WAS? It's Apache, right?"
    Me being relatively ignorant about these specific down-to-earth technical sides to the WAS, means I have to ask: What IS the "web server" part of WAS...? Is it a brand new built-from-scratch web server, or did SAP bundle a 3rd-party product like Apache into the "basis" system?
    Trond

    Hi Trond,
    good question. The SAP Application Server evolved into the SAP Web Application Server back in 2000 with the addition of the Internet Communication Manager (ICM). The ICM support the HTTP protocol (a web sever) and was written complete by SAP. SAP then introduced the SAP J2EE Engine, this to contains support for HTTP.
    In a full blown Web AS (ABAP + J2EE), requests are sent to the ICM and then passed to either the ABAP stack (BSP apps) or the passed to the J2EE HTTP port if the request is for a J2EE web app.
    So in short, SAP wrote their own Web Server...thus you don't need to purchase 3rd part web servers.
    Hope this helps!
    Cheers,
    Jeff

    what does 'the activation server is temporarily down' mean?

    That you may have jailbroken your phone. You may have used that computer to jailbreak a phone. You may have a bad hosts file on the computer because of that. There are many reasons, but generally those are the main ones. According to this http://www.apple.com/support/systemstatus/ there are no system outages.

  • How to find what port the admin server is running

    how can I find out what port the admin server is running on a server?
    thanks,

    Hi
    Go to your domain root folder/config and open config.xml file in any editor. Search for the name of the admin server which is typically like AdminServer and under this tag see if you have a tag by name <listen-port>. If yes, then you should see the port number. If not, it means it is running at default port of 7001.
    If you have admin access, i hope when you login you will be giving url like http://adminhost:adminport/console. Now this adminport is the port on which admin server is running. If not, then check config.xml file.
    Thanks

  • What does the lock with a circle around it mean in the top right corner of my iPhone 5c

    What does the lock with a circle around it mean in the top right corner of my iPhone 5c

    It means that your screen rotation is locked. Open up the control center by sliding your finger up from the very bottom of the screen, and click on the screen rotation lock symbol, which is the same symbol you see on the status bar.
