Shared logins and performance

I am upgrading MS Access applications to SQL Server 2012 back ends. We're currently approaching SS access with a single login shared by multiple users, but less than 24, for the same application. I'm having trouble finding documentation regarding
what performance effects (if any) we will have from SQL Server using this single ID approach. Does anyone have some information regarding this?

Hi SteveChicago,
Based on my understanding, you want to know if it can cause a performance issue when sharing a single login with multiple users.
As Sean mentioned, share a single login with multiple users could cause a security issue rather than a performance issue.
A login is a security principal, or an entity that can be authenticated by a secure system. Users need a login to connect to SQL Server. As a security principal, permissions can be granted to logins. The scope of a login is the whole Database Engine. So
I recommend you to create different logins for multiple users, and grant them property permission to access different database. To make sure every has his own login with different permission, it’s better for us to manage databases. About how to create a login
and map the login to a database user, please refer to this article:

HT1461 Remote Login and sharing

We are trying to remote login and shareing with network computers and have not been successful. Any help would be greatly appreciated.

Lots of people have been successful, so it does work.
Can you explain where you want to share from and to (local, across the Internet, via VPN, etc...)
Can you tell us what you tried.
Sharing within the same network is a easy as enabling System Preferences -> Sharing
Remote Login for ssh
Screen Sharing for, well screen sharing
File Sharing
Sharing across the Internet is best done using iCloud and Back-to-my-Mac, assuming you are running Lion 10.7.2 (or newer).
If you do not have that version with all Macs involved, or you are using mixed systems, then we need to know what.
The least troublesome across the Internet screen sharing and file transfer would be TeamViewer.com, and it is cross platform..
Once you give us more details, we can tailor the advise to your needs.

Shared services and workspace architecture(How we can find out req &respon)

Good morning Hyperion folks,
Does any body have any document or PDF about workspace and shared service architecture...How these both components are communicate each other..any idea or any document..while communicating of these if anything goes wrong,,where we need to check, what is exactly the problem (any suggestible logs)...
Company are doing big mistake by using this hyperion tool ..These guys are not supporting and even they don't know much about the tool apart Product dev team..and that too they are not disclosure any documents related product...
**Does anybody found any kind performance tunning guide or lab guide about workspace and shared service HFM,Planning...** I have never seen component wise documents and tunning guide and recommendations.
I am strong opnion about hyperion is,we would not get any support from oracle and documents so He can migrate Cognos TM1 and Finance management etc........

Thanks john For ur reply ..i have seen these documents long ago ..i am asking about Shared services and workspace architecture and how these are functioning and where we can find out communication error and slow login issue with workspce and shared services.. How authentication is log on ..is there any machanisam they are using for authencation ...We are using OpenLadp ...
Ex :1.Per suppose log on to workspace that request goes to shared services directory and it will check whether that user is exists or not on Shared services tables ...here what kind of alogirtham using to aunthenticate user...How we can diagonse this process taking to much time,,,is there any specific logs related this (If logs are exsits how we can find out)...
2.Once authencation done successfully and responce send to workspace and populate workspace home page...then i click on application button (FM application) and it's taki ng to much time to load HFM page.To this where we need to look whta excatly problem? what are logs file helpful to us to diagonse..

Screen Sharing freezing and high CPU usage

Hello all,
I use screen sharing to remote my mac mini as a media server connected to ma HD TV to play movies, music and surf.
Since I upgrade to mavericks on my macs (Macbook Pro Retina and my Mac Mini) I have some troubles with the screen sharing feature.
No problems with the login step, the connexion is fast, all permissions are OK (I saw there were a bug with some RDP release) but sometimes, when I use fullscreen software as VLC, Firefox, etc (not the native apple full screen feature, I just clic on the + at the top of the window), my sreen sharing freeze and I can't do or move anything on the remoted mac mini. I'm unable to close (or reduce) the screen sharing app too, it's totaly busy (But I can see the movie or the website on the 2 computer, there is no deconnection)... I have to kill the process through the monitoring activity.
During the freezing time, I try to use vnc light from my Iphone and I have no problem, I can move the mouse, reduce le VLC windows... As soon I reduce the VLC windows, the screen sharing works again. I also use the logitech TouchMouse to remote the mouse, everything work fine.
Here are a screen shot of the monitoring activity of the Mac running the screen sharing app, we can see that there is a very high CPU usage when I use VLC in fullscreen on my mac mini. The first is in normal mode. The second is in freeze mode. Screen Sharing is named "Partage d'écran".
Can someone help me to fix that, everything works fine with Mountain Lion.

I have a Macbook Pro 13.5" 2.8 GHz 4 core (2 real, 2 hyperthreaded) i7 machine running with 1920X1200 display, 3 virtual screens and VMWare adding a few virtual screens (full sized). I have another Macbook Pro 15" with 2.6 GHz Haswell 8 core (4 real, 4 hyperthreaded). I see the problem using Screen Sharing on the 15 inch (Retina screen) mode simulating 1920 X 1200 pixels using Screen Sharing to the 13.5" Macbook Pro.
When I get the ScreenSharing problem, I have identified it as related to the VMWare screen on the 13.5" Macbook Pro being shown through Screen Sharing on the Retina Screen. Before you conclude it is a VMWare problem, the computations are only on the Screen Sharing client side, not on the server side running VMWare. The mouse gets unusable through Screen Sharing. If I physically move the mouse on the 13.5" Macbook, no problem. If I switch virtual screens, the Screen Sharing goes to normal processing.
I see an appearance of a compute-bound thread on the Screen Sharing client. It takes 100% CPU on one thread, the machine as a whole is 12.5% busy (the performance monitor considers all 8 threads as equal when in fact, they are not).
A few more pieces of information. The VMWare client ends up having a lot of overlapping windows with a lot of changing graphics. My mouse runs into problems especially when it is overlaying a changing plot (Perfmon running in Windows 7, or updating email client). It does turn out that VMWare has a "native" VNC server built-in and I tried to connect to the virtual screen using the Screen Sharing Client on the machine with computing problem and voila!, no problem. I end up having a Screen Sharing Client running native running screen (supposed to be VNC, but I have not verified that) sharing protocol on a virtual screen that is NOT the VMWare virtual screen and a separate session using actual VNC protocol using the VMWare VNC server. It works perfectly fine.
If I may hazard a guess, I think I know what the bug is, or at least, what is the nature of the problem that I have. The rest of you may have a different bug. When I have difficulty, it is because I am on a window that suppresses the dock, both in remote virtual screen and on the local machine showing the screen. Two docks are suppressed, one remote, one local. Throw in overlapping windows with changing graphics in the overlapped windows and toss in a mouse on top of that. I think that the Screen Sharing is trying to refresh overlapping windows with mouse and going through the suppressed dock calculations and never converging on what the picture should be. The mouse ends up being the visible cue that shows the time frame for iterating the windows - flickers with a timeframe of greater than a second. That is far greater than the screen update time. It is totally compute bound with all the overlapping stuff that it is deconflicting. At least, that is what I think is going on.
Meanwhile, the VMWare VNC server appears to send out a single graphics context and causes the Screen Sharing client to converge to a picture. Note, the mouse appearance is very different when attaching to the VMWare VNC Server rather than the ScreenSharing native server. I see two mouse renderings, the virtual machine remote and a mouse rendering from my Screen Sharing client side. They are mostly in sync in position unless I move the mouse very quickly. If I use Screen Sharing client and server instead, I usually see only one mouse, the client side's mouse rendering.
I have a solution for my problem. It is similar to using a different VNC server/client pairing. I will use a VNC server for the systems giving me trouble that is not Screen Sharing Server exercising a probable bug in the Client (though, it could be a problem in the design of Screen Sharing itself).

HT4968 How can I take a shared calendar and recreate it using my personal ical rather than having to share?

Here's the deal. I stepped into an administrative position last fall and began building an entire calender schedule for our summer 2014 program. I put a lot of work into building two months, however I have only just realized that the apple ID is for the former person who had my job (she left herself logged in on the mac I am now using). My fault for assuming the apple id and login would be the same as the email account I am responsible for.
I did manage to share one of the calendars I created using her apple ID, so I still have access, however, I'd feel better if I could somehow take this "shared" calendar and keep it as my own using the apple ID for the email account I'm responsible for. In other words, is there a way to take a calendar that was shared with you by someone else and save it under my apple ID as MY primary calendar? I'm paranoid that this former employee will delete said shared calendar and I will have to start from scratch...

Before you start see if you can export the calendar to a .ics file via the File ➙ Export menu option. In your own account import the .ics file and that, hopefully, will bring in all the work you've done so far.

Menu tabs disappear completely after login and appears if only i press on item node at hire level

I'm using a Menu Model to Create a Page Hierarchy in my adf application on Jdeveloper 11.1.2.3.0
it is in three levels level 1 have 2 item nods (home - Help) displayed as buttons
                            level 2   contains 5 item nods about the managements displayed as tabs
                            level 3   is about reports displayed as list
the point I have apply security in the application using Adf security wizard and i assign roles and users and grants
all works fine but level 2 tabs disappear completely after login and appears if only i press on Home item node at run time
I create 2 users (admin) has all roles and can view all tabs in level 2 of my navigation and another user (emp) which can view one Tab page in level 2
Point 1 --the item nod are rendered according the #{securityContext.regionViewable['oracle.view.pageDefs.RentManagPageDef']}     (EL ) expression language
and other item nod render property are set as the same but in the page name definition
it works fine
_ Point 2 in my page template I set #{menuInfo.rendered} for renderd property of the command navigation item
it works fine
- point 3 I add a go link in my template to explicit perform log in log out from the app and redirect the user to the required page
Destination is
#{securityContext.authenticated ? "/adfAuthentication?logout=true&end_url=/faces/wearhouse.jsf" : "/adfAuthentication?success_url=/faces/company.jsf"}
and its also works fine
the problem is in the level 2 navigation tabs which is diaper after explicit log in the app directs the user to the correct page successfully
But the tabs are not rendered till I press on home button on Level 1 navigation it appears and it appears correctly cording the logged in user validation
in another words i log in as user (admin) i get directed to the successful log in page in the link go but level 2 tabs are invisible or not rendered at all    I click on Home button in level1 navigation the tabs
become rendered or viewable and i navigate normally
I log out as admin the level 2 tabs becomes invisible again
then I log in as (emp) i get directed to the successful log in page and level 2 tabs are still invisible or not rendered
I click on Home button in level1 navigation the only one tab the user emp authorized to it gets rendered (appears)
and its semi correct behavior because this is what I want him to see only
my tries to find solution
I tride to use
#{securityContext.userInRole['division']}
on the menu node item   I found same behavior level 2 tabs gets hidden till i click on home link at run time
I tride to use #{securityContext.authenticated} to control item nods rending
all tabs remains visible and i dont want that ain adition if user clicks on a tab of page he has no authority on it i recive server error
I read 30.7 Creating a Login Page in the Fusion Developer's Guide for Oracle Application Development Framework to finde about redirecting user
and it is using the same as i did from adf tutorials
I tried to make new navigation app on fast
maybe i made incorrect change in any stage of my original app
but I found same behavior
I tried to set disabled property instead of rendered property the tabs are always rendered   but I got server error when I click on a tab which a user does not authorized
So I doubt maybe problem in the El or the way I use to control rendering item node
or there additional step to stop all the tabs disappear after login
I hope please some one Help or tell me what i have to read about in the developer guide or interface developer guide or article on the web
I'll be gratfule
I know maybe it is small issue but help me please

Hi,
have a look at the sample that comes with this article: Oracle ADF: Security for Everyone It uses resource remissions to authorize panel tabs.
One test to run is to print the outcome of the security evaluation (e.g. output text) to see what it returns.

Creating a login and password in the forms

I have been trying to create a username and password to access the database that I have created using Form Builder. This is the code that I have created....the syntax is correct but its not performing the task i.e direct the user to a different form
DECLARE
LOGINNAME VARCHAR2(20);
PASWORD VARCHAR2(20);
BEGIN
IF LOGINNAME = 'CSR' AND PASWORD = 'CURRIE'
THEN
CALL_FORM ('C:\ClothingCloseout\Menu.fmx');
ELSIF
LOGINNAME = 'MGMT' AND PASWORD = 'SANDRA'
THEN
CALL_FORM ('C:\ClothingCloseout\Menu.fmx');
END IF;
END;
I also tried using the same login and password through which I get connected to teh database but that does not work either....Thanks for the help!!!

Hi Ashley,
The compilation is successful because there are no syntax errors. When the code is executed depends on where you have put this code (On-Logon trigger, etc).
In this situation, it looks like the 'code' has not been executed YET because the event has not been triggered OR it has successfully gone through ie - the IF test for loginname and pasword was not satisfied. Therefore, the call_form was never performed. (Your code does not prompt the user to input 'Loginname' and 'Pasword'). In this case, loginname and pasword are NULLs.
Regards,
John

In the Aurora "about" window it notes it automatically sends Mozilla info like usage and performance, etc. Does disabling telemetry etc in options disable this?

As the questions says, does disabling the telemetry options in the browser settings disable any information, usage, and performance sharing as it does in Firefox proper, in spite of the blurb in the Aurora "about" window?

hello Alxlight, the text in the about-dialog is static and should just inform users about the default configuration in the experimental aurora/nightly channels of firefox. when you decide to disable the various settings in ''options > advanced > data choices'' this data won't be submitted to mozilla, despite what the about-dialog says...

Hyperion EPM: Will Oracle Express suffice for Shared Services and Registry?

Hi.
I'm trying to install Hyperion EPM on Linux to make use of the Hyperion Interactive Reporting server components to allow report scheduling, web delivery of reports, etc. My data sources will all be MySQL. I'm at the point where I'm attempting to use the EPM Configurator for setting up Shared Services and Registry Database Connection. It seems my options for choosing a database on which to allow Shared Services and Registry data to reside are limited to 3: Oracle, SQL Server or DB2 (noticeably absent is MySQL)
So, it looks like I'm going to have to install an Oracle DB instance at the very least.
My question is this:
Can I get away with just installing Oracle Express for the Shared Services and Registry or will I have to install a full blown Oracle DB instance?
Thanks
-- Tom

Hi, I confirm that you can use Oracle Express for Shared services and registry. We have installed the complete EPM platform on a single virtual machine using Oracle Express. It’s interesting to use it because Oracle Express use less resource. We can run this virtual machine on a computer that only have 4GB of RAM and get good performance (for a single user).
I recommend using it for proof-of-concept and Bootcamps.

Workspace- login and password

Stability and Performance Issue With Aperture 3

I'm running Aperture 3.0.3 on my iMac. This is a switch from Adobe products and I'm having a ton of stability and performance problems.
Environment:
* My library is about 32,000 images, about 1/3 of which are 21 megapixel, the remainder are 10 megapixels or smaller.
* I have no smart albums.
* All images are referenced and live on an external FW800-connected RAID5 array. The library lives on my internal drive.
* I have an Apple Cinema display connected through the mini-DVI port.
Here's what's happening. Initially, Aperture starts up fine and things are peachy. After a few adjustments -- particularly cloning or patching, rendering becomes slow. It becomes slow as in a minute or more. On a 21 megapixel file, this is an incredible productivity killer. Here is what I've tried to make Aperture go faster (not all at the same time):
- Log in holding the shift key to make sure nothing but core system stuff is running
- Rebuild Aperture library
- Defragment internal hard disk using iDefrag
- Export a subset of images to a separate library and work on them there
None of these has had the desired effect. Worse, if I switch to full-screen mode, the whole interface becomes balky and can become unresponsive to the point where the only way out is to cold reboot the computer. Cmd+TAB doesn't even work.
I can't imagine this is an experience shared by many users of the screaming would be deafening. Lightroom and Photoshop are insanely fast by comparison so it can be done -- and on this computer.
What are the best practices for speeding up Aperture?
Thanks,
Steve

Have you tried the Bergsma BAsh?
Many of us who have upgraded our library's over time have cleaned out caches using a technique discovered by Matthew Bergsma . It cleans out some obsolete files that significantly slow aperture 3 down.
Here's what you should do:
Quit aperture
Navigate to your aperture library.
Ctrl click library and select show package contents
Open the thumbnails folder and drag contents to trash.
Then delete the entire contents of the following cache folders:
Hard Drive/Library/Caches
Hard Drive/System/Library/Caches
Hard Drive/Users/Your username/Library/Caches
You may also like to delete the preferences file but that's up to you.
~/Preferences/Library/com.apple.aperture.plist
Open Aperture:
Rebuild Thumbnails click library - photos
Then select one photo and apple(command) A to select all.
Then go to the photo menu and choose generate thumbnails.
It'll take a while to go through them all but once it's all done Aperture 3 should zip along
You can read Matthew's original post:

Restoring the NCS Database
If you are restoring the NCS database in a high availability environment, see the "Restoring the NCS Database in a High Availability Environment" section. To restore the NCS database from a backup file. follow these steps:
Step 1 To view all local repository backups, use the below command:
show repository backup_repo
Note If possible, stop all NCS user interfaces to stabilize the database.
Step 2 Manually shutdown the platform as root.
Step 3 Using the CLI, perform one of the following:
•Restore the appliance and application backup by entering the following command:
restore testbackup-yymmdd-xxxx.tar.gpg repository backup_repo
•Restore only the application backup by entering the following command:
restore testbackup-yymmdd-xxxx.tar.gpg repository backup_repo application NCS
Step 4 Click Yes if a message appears indicating that NCS is running and needs to be shut down.
Note If the restore process shuts down NCS, a restart is attempted after a successful restore. The appliance will then restart and you will have to again login and restart the dbserver, and the platform manually as root (make sure you do not start with dbclean, else you will loose your recently restored data).
The CLI displays messages indicating that the NCS database is being restored.
