display only user information sessions

Hello

I am looking for a solution to grant limited access to v$ session, so the specified database user can list only sessions held by himself.

something like a public version of:

Select * from session $ v

where username = user;

I can do this with v_$ session for the specified user. But there is not much sense in it since v_$ session shows all sessions.

So is it better?

Thank you

SYS, grant select on v_$ session directly to a user with grant option option. (Someone who is a DBA is still a good choice)

As this privileged user create a view by using the same query, you have above. (USER_SESSION is a logical name)

create a public synonym for your point of view USER_SESSION.

Grant select on USER_SESSION to specific users, or the PUBLIC.

In this way, v$ session is not available to the average user, but is USER_SESSION and works the way you want.

Show only user information after the connection

Hello world

I hope someone can help me please, I'm new to databases and programming.

OK, I just created my first page of the login of the user (using the dreamweaver builtin functions). Nowi have successfully built a MySQL database, insert a table with username, userPass and e-mail. The login page works correctly and redirects to the authorized page

Now, this is where I get lost. On the authorized page, I want that it lists the information related to that user only, IE display their username and your email address. What I can't work. I'm sure you must filter to show only the logged-in user, but I can't see anything at all.

Help, please

Automatically display the user information

So I'm working on this website of the school project, it's a pretty simple site in Dreamweaver. I created a log in the site and I use MM_Username to show the connected to the user. How can I go to show information of the user (name, first name, telephone number etc.) on a wall that they display all sorts of different things in (to sell, animals lost, happening, etc.
Thanks in advance!

Task Manager

my task manager currently has two active users in the console session. I am the only user of the computer and when clicking on USERS it always shows only one user. What or OMGE could be the cause.

Hello

Open the Task Manager->, click on users-> right click on another user who isn't currently active and choose log off.

This can occur when the user account is not properly disconnected.

I hope this helps.

Restricting the views to DISPLAY ONLY the rows CreatedBy current connected user
I want to user Oracle views - restrict the view to DISPLAY ONLY the rows CreatedBy / current OwnedBy signed / authenticated user!

What are the different approaches, I have something with;
setNamedWhereClauseParam, but this must be called on each ManagedBean in the constructor, as I have now!
This approach caused the button Edit/Save which simply calls the commit to stop working. In a complete view of all the lines, there is no problem, with
the button requesting validation the selectedRow in af: table.

Other means?

Thank you
It does not appear that your view object extends the framework with custom code extension class in dealing with populating the bind variable by default.

I myself put in place as long as the administrator and am the only user, but my wife's name is still on display in the user records

original title: problem strange user

Hello people out there... My problem is that I got on the computer of my wife which is a HP Pavilion with Vista home Premium. I myself put in place as long as the administrator and am the only user... However my wife's name still shows under the user folders, i.e. 'C:\User\jenny '. I went to the sections of the user to delete, but it does not appear, it shows me only... also when I try to delete the folder of the user, the delete option wonder if I want to delete my account... My folder is located on the right of the Start button with more programs from the main menu, but my wife is located under the main C: drive I obviously did something wrong when I set up my user account, but I have no idea... so if anyone of you people can help me, I would be very grateful... Thank you.

If you change the name of an account, the name of the associated in C:\Users folder does not change. As far as I know, there is no way to change this.

Error "Unable to get user information" when you try to open a session

Ahoy hoy,
When you try to connect to the workspace, everyone's is "unable to get user information".
I think the problem might come as our domain controllers have changed IP address. If it's still weird that I entered the domain name, not a specific domain controller. It could be a coincidence, I guess so.
When I log in https:// HorizonWorkspaceFQDN 0/SAAS/login/0 to use a domain account and check, it connects fine, but there is nothing outside of "details of the error: Null".
Any help would be greatly appreciated.
See you soon,.
Craig

All fixed now. Found that this /etc/resolv.conf pointed to a DNS server that had his IP has changed. It was put in the Pool of IP on initial Setup. I updated /etc/resolv.conf on workspace all virtual machines and also updated the Pools of IP.

Rebooted and everything got back online. Happy days.

I can't open my pictures folder. Error message says I don't have permission! I ran disk utility and found no errors. How this could have happened and how can I fix this problem? I'm the only user.

Suddenly, I can longer open my pictures folder. I tried to move a picture to the folder to see what is happening and received an error message saying I was not allowed to display the contents of the folder and if I move the picture here, I won't be able to see. I ran disk utility and found no permissions error.

How this could have happened and how can I fix this problem? I'm the only user. No one else has ever physical access to my computer. However, I sign up for Skyhub a few weeks ago and copied the contents of my Macbook it. Since then, a "Remote disk" icon on my hard drive. This would be part of the problem?

Select it, choose get the information on the file menu, open the section sharing and permissions and give you access.

FaceTime will not open on my Macbook pro (el capitan). Message: "FaceTime close unexpectedly. Click Reopen to reopen the application. Click report to display more detailed information and send a report to Apple. "Please help me.

Please launch the Console application in one of the following ways:

☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

Step 1

For this step, the title of the Console window should be all Messages. If it isn't, select

SYSTEM LOG QUERIES ▹ all Messages

in the list of logs on the left. If you don't see this list, select

List of newspapers seen ▹ display

in the menu at the top of the screen bar.

In the upper right corner of the Console window, there is a search box to filter. Enter the name of the application crashed or process. For example, if Safari has crashed, you would enter "Safari" (without the quotes).

Each message in the journal begins with the date and time when it was entered. Select the messages since the time of the last fall, as appropriate. Copy to the Clipboard by pressing Control-C key combination. Paste into a reply to this message by pressing command + V.

The journal contains a large amount of information, almost everything that is not relevant to solve a particular problem. When you post a journal excerpt, be selective. A few dozen lines are almost always more than enough.

Please don't dump blindly thousands of lines in the journal in this discussion.

Please do not post screenshots of log messages - text poster.

Some private information, such as your name, may appear in the log. Anonymize before posting.

Step 2

In the Console window, clear the search box, and then select

DIAGNOSIS AND diagnostic USE information reports ▹ user

(not diagnose them and use Messages) in the list of logs on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points downwards. You will see a list of reports of incidents. The name of each report begins with the name of the process and ends with ".crash". Select the most recent report on the process in question. The content of the report is displayed at right. Allows you to copy and paste to validate all of the content, text, not a screenshot.

I know that the report is long, perhaps several hundred lines. Please report all this anyway. If the report is only a few lines, make sure that you have disabled the search box.

If you don't see any report, but you know, he had an accident, you have chosen diagnostic and using the list of Log Messages. INFORMATION on the USE of DIAGNOSTIC AND choose instead.

In the interest of privacy, I suggest that, before posting, you change the UUID ' anonymous, ' a long string of letters, numbers and dashes in the header of the report, if it is present (it cannot be). "

Please do not post other types of diagnostic report - they are very long and rarely useful.

When you post the journal excerpt or the accident report, you might see an error message on the web page: "you have included content in your post that is not allowed", or "the message contains invalid characters." It's a bug in the forum software. Thanks for posting the text on Pastebin, then post here a link to the page you created.

If you have an account on Pastebin, please do not select private in exposure menu to paste on the page, because no one else that you will be able to see it.

Capturing information session registration

Hi all
Jdev Version: 11.1.1.7.1
Requirement: must enter the user name and roles in a table when a user connects. In this context, seeks to determine the means to achieve. More specifically, seeks to the exact spot as well as the information above. is captured only once per session and at the beginning of each session.
Explored approaches:
i. Web filters (filters in web.xml file) - excluded that this is not an optimal as option that gets called every request.
II. Landing Page executable - excluded, as this will be executed on every refresh as well as on the tabs of the browser within the same session
III. lifecycle listeners - once again, they are at the page level and not at the session level - thus excluding it.
I explore a different approach I'll keep this thread updated. During this time, wanted to see if there are better options that the forum here.
