How to make single page can only be accessed by one user at the same time

While a user is accessing a page and modifying the data in this page. Other users are blocked for this page. How can it be realized?
Any ideas or help are appreciated.

So means there are n number of users and you want that if any one of them accessing this page then nobody else will have access to that page.
-> Use flag in DB and whenever user accessing that page set the flag 1 after login and check condition while other user login.
-> After logout back to 0.
Well this is possible one of the solution, not the best one.Try to find some other also.

Make PDF formular only accessable for one user at the same time?

Hello!
I designed a formular which needs to be filled in by different departments of our company. Unfortunatly the DF can be opened by several people at the same time. Is there any way to "lock" the PDF, fot that only one user has access to the formular at the same time, like e.g in MS Word Docs?
Please help, I coudn´t find a solution myself.
Thanks!

This needs to be done on an OS level not by the application.

I think Justin is correct and you should have statistics in place and a reasonable partition scheme so that the optimizer selects the correct partitions rather than telling it what to do. You paid a lot for partitioning after all.
There are some, possibly misguided, examples in the manuals showing how to create a view so you can delete from a single partition without specifying the partition criteria in the delete statement. This in effect turns partitioning back into DIY partitioning i.e. separate tables, union all and pretend its a single logical table using a view. But backwards.
So to do what you want you just assume the partitions are separate tables, and then use union all to glue the ones you want back together.
select * from sales partition (sales_q1_2000)
union all
select * from sales partition (sales_q1_2001)
union all
select * from sales partition (sales_q1_2003)
union all
select * from sales partition (sales_q1_2004);It probably goes without saying that as well as making the expensive version of partitioning behave like the free alternative, there is the possibility that it will perform like it as well.

You can open a single or multiple ports to a single device or different ports to different devices, but you cannot open the same port to multiple devices via the AirPort Utility for the Apple routers.

What is the SQL*Plus syntax to select multiple partitions from a partitioned table?
Example: select tran_date from transaction_table (partition1, partition2, partition3);

I can only hear sound from one side of the head phone

I've plug in my bass guitar through a cord and a converter in the line in port on my PC. Then checked 'listen to this device' (head phone) which is connected properly as it worked perfectly when I play any sound in ma PC. But when I play my guitar, I can
only hear it from one side of the head phone. How to fix it!?

Is that compatible to give output from both sides (R + L) ? Can you check same thing on other system ?

How can i share documents with different users on the same mac?

How can i share documents with different users on the same mac?

Shared how? The other users can read the documents or you all can read and write the documents?
The first is easy just place the documents in /Users/Shared anyone can access the files there and the other users will be able to read them.
The second is a bit trickier.

how can I get rid of multiple pictures at the same time?

Adobe Bridge, lightroom and your file browser (windows explorer or Mac Finder) can select multiple pictures at once and then delete. If you are looking for more than that for information, you will need to be more specific at what your doing, what OS you have, and version of software your using. If necessary post screen shots so we can see what your doing. The more information we have the more detailed of an explaination can can give back to you.

How many meetings can be opened by one account at the same time?

I've tried Adobe Connect trial version.
There are few questions about the product.
1.How many meetings can be opened by one account at the same time?
   I could open 9meetings at the same time using other PCs. What is the limit?
2.What is the maximum of students in a meeting?
   I'm thinking of buying monthly/Individual product.
3.The meeting never end even though host is out of it. But we want to control.
   Can host close a meeting so that all participants are out of the session?
Thanks for your attention.

This depends on your licensing.
If you are using a Named Host license, then you can open one meeting at a time. If other members of the Meeting Host group are present in a room, then it should allow you to have multiple rooms open, one for each Meeting Host licensing being used.
If you are using the Concurrent Learner license, then each meeting you join uses a different licenses, so as long as you have concurrent seats available, you can open as many rooms as you want/need.
Maximum number of attendees (students) would be your room's concurrent maximum, less your self. The monthly version of Connect offers 25 concurrent attendees in each room, so that would be 24 students and you.
The meeting does end after it is dormant (no host) for ~15 min, however you can use the End Meeting function (Meeting > End Meeting) to close the meeting and remove everyone, including yourself, from the room.

I can not establish more then 1 call at the same time

Hi,
I have SPA9000 with four active accounts. I can not establish more then 1 call at the same time. Accounts are all in registered state. The field in SIP tab, Default Group Line:, is by default: 1,2,3,4 which means if line 1 is busy try the next one in the order ( in this case number 2). But this is not happening. It always tries to dial out with the first line (account). There is no problem with the provider and I don't want to specify groups of userID's and to assign them special line for dialing out.( by the way in this way it is possible to establish more parallel calls, but then each user will always have to dial thru specific line only). Please help me to find out if the SPA is faulty or give me some workaround, so that when I try to make a call , if one line is busy to dial out thru the next available.
P.S. I suspect that SPA9000 does not notice when the line is busy or not. Maybe there is some issue with the Control Timer Values (sec) on Regional tab.
Thanks,

no it can only be one person at a time

Can we use Badi BBP_SOURCING_BADI and BBP_DETERMINE_LOGSYS at the same time

Hi everyone,
We need you help. We are working in SRM 7 and ECC 6 EhP 4. We have a doubt. Can we use badis BBP_SOURCING_BADI and BBP_DETERMINE_LOGSYS at the same time in a classic scenario?
We want to create the contract in ECC, and then we want to return the SC in SoCo in order to create the PO with the SC and the contract.
We activate both, but the SC is not returned in SoCo.
Thanks,
Ivá

Hi Ivan
You can use both badi to change srm standard behavior.
but one shopping cart item and it can have only one follow on document either Contract or Purchase order.
i presumed that you want to use same sc for two purposes to create both SC and PO but it is not possible.
for example
shopping cart item has follow on document created as a contract But you need to create a another shopping cart to create a Purchase order w.r.t that contract .
Once follow on documents are created sourcing flag will be removed .- rule
BBP_SOURCING_BADI - you can write your custom logic and make way to cockpit .
BBP_DETERMINE_LOGSYS - Determine your logical system.

Can you have more than one user on the new ipad?

Can you have more than one user on the new ipad?

You cannot set up more than one user account on the iPad if that is what you mean.
Obviously families will share an iPad, but they are really meant to be single user devices with one Apple ID only on the iPad. Multiple ID's on one iPad can become a bit of a hassle to deal with.
There is no way to lock apps or email accounts so that can become an issue as well. If you use the built in mail app for email, whoever is using the iPad can read your email.

SerZak is correct. There is a ten device limit. Yoy would still have to be signed into the correct ID in order to sync the Movie, even if you do not use Automatic Downloads, so the 10 device limit would still apply.
Your Apple ID can have up to 10 devices and computers (combined) associated with it. Each computer must also beauthorized using the same Apple ID. Once a device or computer is associated with your Apple ID, you cannot associate that device or computer with another Apple ID for 90 days. You can view which devices or computers are currently associated, remove unused devices or computers, and see how long before they can be associated with a different Apple ID from the Account Information page in iTunes on your computer:
