2. how to login user out?
Thanks

  • Using mavericks, how to control login apps on imac

    Hi, just bought a new imac 27" 2014, using Mavericks, and restored from backup of the old imac. When I boot up, mail, firefox automatically load. I want a blank screen with nothing open. Where do I find the control for this? Not coming up in spotlight search...

    Open Users & Groups preferences. Click on the Login Items tab, select the undesired items, then click on the Delete [-] button. If nothing is there then open General preferences and check the second option.
    Next, select Shutdown from the Apple menu. You will then see this appear:
    Uncheck the box.

  • How to control the users' authorization?

    Hi All,
    Please help me for the below scenario in system.
    A & B users have access to same business role (Ex: SERVICEPRO) in Web UI.  However, user A should be able to create and edit anything, but user B should have only display authorization (User B should not be able to create and edit anything in application). 
    Could you please suggest me how/where to control the authorization for these users? 
    Regards,
    Maddy

    Hello Maddy,
    Hello Maddy there is no specific authorization object for user. That can be done with PFCG menu. You need to play around with the PFCG Role “Menu”. The solution for your scenario is  as below:
    When I say changes in the menu, I mean changes in the menu tab of the PFCG role assigned to the user. You have to delete the UIU component from the respective folder. In the present case I have taken Sales folder - transaction Opportunity. This holds good for any transaction (eg activities, lead, etc). The moment you delete the link (UIU_COMP link) and save the PFCG Role the authorization tab will become red. Reason being that specific authorization of create/display is deleted. You need to go to authorizations make all green and generate the profile.
    You can also refer to the link below, which will be of help to you for better understanding.

  • How to find login user with the largest account

    Hello. I'm looking to put together a bash script that can do two things: (1) determine the shortname of the user with the largest account in /Users and (2) look up their full/long name. I'm going to use this script to help identify who the user on a computer and while I know that's possible that a sometime-user may have a larger account than the normal-user on any given computer, the results of a script should be sufficient in most cases for my needs.
    I'm not sure the best way to around this. I know that I can use "du -m -d1 /Users" as root:
    root on torchwood
    [ ~ ]$ du -m -d1 /Users
    157 /Users/admin
    128 /Users/johndoe
    70890 /Users/dancollins
    21746 /Users/Shared
    92920 /Users
    I know that I can also use "dscacheutil -q user" to get a full list of all users on a system.
    How can I get both the short and long name of the user with the largest account in the /Users folder?

    We're running JAMF Recon for inventory and my supervisor wants to create a report that lists the primary user of the Mac... assuming that the largest user account may be the primary user. In this case, disk space is not the issue, the top admins simply would like to be able to associate names with individual machines. This isn't the most elegant way to do it and it's not fool-proof, but it'll be correct more often than not, which they're satisfied with.
    Can I ask one more question? Using your script, I've started testing with one building and on a number of Mac, the "admin" (shortname) account is turning out to be the largest account. Is there a way to exclude the admin account from consideration?
    Thanks...

  • How to find out maximum number of login users?

    Hi all,
    Is there anyway to find out what is the maximum number of login users since a database is started? Maybe I should ask, what's the largest number of sessions has been opened in a busy time of a database since it is started?
    I know v$session is my target. But how can I find out hte HWM of opened sesions?
    Thanks.

    Thanks Serch-NET. That's what I'm doing today. I should be a little more specific. I'm looking for a script that lends itself to automation. A script that can determine all the databases on a given server, find their background dump dest., grep all alert logs and return the highest of the HWM's. This is all scripting I could do myself, but being a follower of the Lazy DBA, I was hoping someone else had done it. :-)
    Thanks again.

  • How to Control authorization for users with certain status for level 2 WBS Element

    Dear All,
    Is there any standard way or enhancement available to control authorization for users with certain status for WBS Element i.e. for example
    Pre-requisite:
    There is only 2 level of project i.e.
    Lev_ WBSE_______Description
    1___ 7-14.E_______summay outage controller
    2___ 7-14.E.2310__ Plant/unit # 2310
    2___ 7-14.E.2310__ Plant/unit # 2220
    Project Controller  (authorization role assigned "Z_PS_OP7_OTGCON_C") have all project level authorization
    Plant/Unit Controller (authorization role assigned "Z_PS_OP7_PLNTOTG_C_2310") have only level 2 authorization with enhancement that we did in system by Z table.
    User ID_ Plant #
    123345_ 2310
    122455_ 2220
    Issue:
    After System Status released and User Status approved the WBS basic date for Plant/Units should be restricted from updating/changing by Plant/Unit Controller level and only project controller should have this authority.
    Solution required: 
    Can any one tell how to control this scenario either by standard or enhancement available to control authorization

  • How to show the login user Id in the upper right corner of each page?

    Hi,
    I was wondering how to show the login user Id in the upper right corner of each page?
    thanks so much!
    cchu

    Cchu,
    The easy question first: applying a style to the welcome message. If you look at the page source, you'll see that #WELCOME_USER# is expanded to <div class="app-user">Welcome: DEMO</div> So to change the style of the message, you need to tweak the style of the app-user div in your CSS, or override it in a style block in your HTML header.
    Now, the tougher question: why the text is wrapping for you. And, really, without seeing your entire page, I can't give a full answer. But I'd suggest that what's most likely happening is that the table column you're putting it in is too narrow, so it's wrapping; try replacing the td tag with <td nowrap="nowrap"> This will force the column to be wide enough to display the full message, but might result in weird formatting elsewhere on the page (depending on what all is in your table).

  • Chat App: how to store the user IP in database when they login.

    hello,
    i am working on chat application. first i made a login GUI form. after login when we run the Chat program, it ask the ip address of the server to whom it want to connect. and if u enter the ip address, it will connect to the server and chat will begin, thats working perfect.
    but i want to show the list of users who r logged on and when i simply click on the user name, chat should begin.
    i have the logic that when any user log in, then its IP address will be stored in the database. this ip address will shown to the online users.
    but i dont know how to store the user information in database when they log in. can any body suggest me wht lines of code i should use.
    thanks.

    i have the logic that when any user log in, then its IP address will be stored in the database. Bad approach. That will only work if this chat is only intended for use on a LAN. If it's used on the internet, then your users' IP addresses will almost always be either a) those of their routers, or b) private IP addresses, and in both cases, multiple users can have the same IP address.
    this ip address will shown to the online users. Why would you want to do that? I want to chat with "Bill", not with "1.2.3.4".
    but i dont know how to store the user information in database when they log in.Do the same thing that you're currently doing to store the IP address, but with the other information you want to store.
    can any body suggest me wht lines of code i should use. This is not a code writing service.
