Only one user at a time

I'm looking for help.
I have two user accounts on my iMac. Both have their own iTunes library file but these both reference to a shared store of music files (to avoid duplicates). I would now like to move this shared music to an external HDD attached to my TC.
My problem is this. If user 1 first accesses the external HDD then when user 2 tries to do so there is a little red icon on the folder and permission is denied. If I disconnect all users from the TC and then retry with user 2 the problem is reversed. It seems to me that only one user account is allowed to access a TC external HDD at a time. Is there any way around this?
In case anybody asks, my reason for moving the files is that I am hoping to buy a Sonos music system, which can read iTunes music from the TC as though it were an NAS, even if the computer is off.

I think you're being misled a bit by the interface: the checkbox labelled "Strict locking" doesn't just allow strict locking, it requires it (and thus disallows byte-range locking). That is, with strict locking enabled, any client that tries to lock any part of the file actually locks the entire file. Access normally depends on byte-range locking to allow different clients to share the database (as long as they aren't trying to modify the same part of it at the same time), but with strict locking the first client locks all others out.

Concurrent program to be submitted y only one user at a time

Hi
I have an issue with one of my reports. The report is using temporary tables, those will under go insertion and deletion while the report is running. So, to make sure that two or more concurrent requests submitted for same report, will not conflict, I want to make my concurrent request to be submitted by only one user at a time.
How can I do that?
Any help is appreciated.
Thanks

The "run alone" box should not be checked. This indicates that this program can only run when no others are running. Pl see MOS Doc 1078462.6 (Custom SQL Concurrent Program Returns NO MANAGER Error). This option should typically not be used.
To be able to achieve what you need, set the incompatibility (as you have done) and then bounce the concurrent managers for the setting to take effect. Pl see these MOS Docs

1. Does not start automatically 2. Only ONE user at a time

When I plug the IPOD it should start iTunes automatically (I have the box checked) but it does not. Never has done that. I have the latest 7.1 version.
Another pain in the rear is that only one user at a time can run iTunes. That stinks. If another user has it open you MUST log off, stop them, log on. They ought to make this work for all users as other windows pro rams do. If it is doing NOTHING with the library then I ought to be able to use it.

That may be true but it is a real pain since when it happens the only way to recover is to terminate all of the iTunes modules with task manager and start it manually. It also leaves the IPOD in a state that says do not disconnect. You can disconnect since nothing is really happening but there is no excuse for this not to start much faster. When you have multiple users it is a real pain. It ought to be able to either end when finished or better yet allow multiple users simultaneously updating from different libraries.
I guess i will just have to get in the habit of treating it as a single user and start and stop it every time I need it and be suer not to let it run. Not nice because that means waiting for larger Podcast downloads instead of having there ready for me when I sign on my computer.

Only one user at the time can execute VE01 (due to blockage of VEIAV)

Hi,
As I understand it only one user at the time can execute VE01 (or MEIS for arrivals). If someone is already executing the VE01 transaction the error-message "Table VEIAV is blocked by user XX" appears. It does not matter if one tries to execute it for different legal entities - no parallel processing seems to be possible.
This is a huge limitation for a global concern with many entities operating in the same SAP instance. Does anyone recognize this problem and are there any ways to get around it? It does not make sense that dispatches (VE01) and arrivals (MEIS) cannot be executed for several organizational units at the same time in parallel?
Thanks in advance,
Mats Hansson

yes I know this problem.
One should not maintain much thru this transaction.
for me it is not more than an emergency transaction, as it is not really more than table maintenance thru SM30
You should investigate what entries/changes the users have to make.
Limit these manual entries by having better data in the system, so that SAP can itself create the entries for this table.
Organize more, less users , maybe just one per company who shall maintain VEFU manually.
Train them to prepare their entries before they start using VEFU.
Explain that they should leave VEFU as soon as possible as the block other users.
assign maintenance windows to the users.

Only one user at a time can log in per client

Server: 10.6.2
Client: 10.5.8
The share point on the server is the default of /Users. Home directories are configured as /Network/Severs/hostname/Users/username. In the "Home" tab of each user, the home directory shows up as "afp://hostname/Users", which is the default when creating a user.
On a given client, only one user can log in at a time. If the first user switches to the login screen without logging out (fast user switching), when the second user attempts to log in, they get an error "You are unable to log in to account "xxxx" at this time."
Looking in the secure.log, the error appears to be "file busy":
Mar 7 12:13:39 G4-MDD authorizationhost[677]: ERROR | -[HomeDirMounter mountNetworkHomeWithURL:attributes:dirPath:username:] | PremountHomeDirectoryWithAuthentication( url=afp://Mini.local/Users, homedir=/Network/Servers/Mini.local/Users/xxxxxx, name=xxxxxx ) returned 16
The server's /Users directory is mounted. It appears to be trying to automount another copy, rather than use the existing mount.
How do I resolve this so multiple users can be logged in at one time? Surely I don't have to create a share point for each user?

I'm glad to hear I'm not the only one encountering this problem, although the fact that this problem has apparently existed for some time is mind boggling to me. The idea that there is some data corruption issue here is not a valid concern. We did this all the time on Linux in my previous life. There is no need to unmount the mounted directory, at least in the default case. The mount point is /Users. Home directories on the server are /Users/fred and /Users/sally. Automounter mounts /Users at the mount point /Network/Servers/serverhostname/Users. Fred is logged in and can access /Users/fred. Now Sally wants to log in. /Users is already mounted. There is no reason to unmount/remount /Users. OS X can see it is already mounted. Just log Sally in - she already has full access to her files.
If Fred and Sally reside on different servers, then there would be different mount points /Network/Servers/hostname/Users - again no conflict in the mount points.
The only solution I can see right now is a separate share point for each user, which is unacceptable. That might work for my two users. It's hardly scalable from a maintenance standpoint.
I do have the problem of fred logging out and sally not being able to get in right away, but that period is probably less than a minute. Wait a minute, then sally can log in.

Is there a way have a file only accessable by only one user at a time

Here's the question...
I want to set up a file so that it can only be accessed by only one person at a time - is there any way to do this?

Turn off fast user switching and autologin, making all users log off before other users can use the machine.

Only one user at a time allowed to open MS Access database on a Mac share

I have an issue trying to open a Microsoft Access database from our Mac OS X Server running on XServe.
The MS Access file is stored on a Share Point on the XServe. Windows XP clients open the database. The problem is that it will only allow one user at a time to open the file. The has previously been operating fine when it was stored on a Windows server.
The Group's permissions for this Share Point allow Read & Write.
Any thoughts would be much appreciated.

Issue with QuickVPN on SA520 - only one user at a time?

Currently, whenever we have multiple users attempt to VPN in - the first user gets in fine, however, any subsequent user is able to connect but repeatedly receives the message that they are unable to communicate with the network, would you like to wait. I'd like to be able to have more than one user connected concurrently to the VPN - any help would be greatly appreciated.

Hi:
Thanks for reporting the issue. Please let us know which OS you are using that is experiencing this problem.
If you are using Window 7 and/or Vista, we already have a fix in our next release image 1.1.62 (MR2).
It would be release soon, either end of this week or early next week.
If you need it earlier, please let me know, I can PM you with a private image.

Only One User Can Access Time Capsule At A Time

This seems strange....
I've been using the Time Capsule without issue for around a year. I can access it from my Mac Mini with no problem. I can also access it from my Macbook with no problem. When it comes to the iMac, I have two user accounts. One for me, and one for my wife. When my wife tried to access it, the Time Capsule blocked access beyond the root. (So we could select TC from the sidebar, then double-click the TC folder that appeared, then the small icon in the top of the window has a stop sign through it with no folders displayed).
Mine is fine - so I tried to fix it by deleting my wife's keychain passwords to the TC. I reset them and it connected her. However, when I swapped to my account I was locked out!
I reconnected, and I regained access - and now my wife's locked out again!
I haven't got the time capsule set to user account access, so I have no idea where to go from here!
Please help!

I am not sure if this issue is happening because of following observation.
The config is using ip 10.2.10.255 in the VPN pool , we cannot use this ip address as this is broadcast ip in the VPN pool subnet. Do the following and then check connecting vpn clients and post results.
no ip local pool ifn_noc_ips 10.2.10.1-10.2.10.255 mask 255.255.255.0
ip local pool ifn_noc_ips 10.2.10.1-10.2.10.254 mask 255.255.255.0

How to : only one user in a branch can do the batch process at a time ?

dear gurus,
In ADF web application, accessed by multiple branch (20), there is a
batch process to create invoices from orders. There are 3-5 users in a
branch. one user can process about 30 - 50 orders to become
invoices.
Business rule is : In one batch process, each users must produce
invoices with gapless invoice number. e.g : user_1 create 30 invoices
no.001 - 030, user_2 create 40 invoices no.031-070 ... and so on...
So we want to protect that at a time, in one branch, only one user can
do the batch process. User_2 must wait until user_1 is done to start
the process.
We use the table below to maintain the latest invoice number created :
CREATE TABLE doc_number
DOC_TYPE VARCHAR2(6 BYTE) NOT NULL,
BRANCH_CODE VARCHAR2(6 BYTE) NOT NULL,
DOC_NBR NUMBER(12) DEFAULT 0,
CONSTRAINT "DOC_NUMBER_PK" PRIMARY KEY (DOC_TYPE, BRANCH_CODE)
The question is :
I think of locking a spicific row of the doc_number table (select ...
for update wait 10) at the beginning of the batch process stored
procedure.
But what if the session/connection left orphan and the row is lockde
forever before the dba kill it ?
So is there a better approach to limit the user execution of the
process ?
Thank you very much for your help,
Krist

Forget it. See http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:4343369880986.
However, if you are dead set on doing this old fashioned thing of trying to emulate paper invoices from a numbered tablet, you could always just let everyone generate all of their invoices with no invoice number whenever they want, then at some time ( say 21:00 every day), take a lock on the table and apply invoice numbers to all of the records with a null invoice number -- which will take only a few centiseconds at most. And let the users/system print only invoices that have numbers assigned. This way, you pretty much eliminate the concurrency issue of various branches generating invoices only in their time window -- yuk, what an awful way to have to do business.
And completely forget about users or branches having their own range of numbers. That is completely nuts. Your database already knows which branch owns which invoice, right??

Locking a JSP Page i.e allowing only one user to access it at a time

Hi,
I have web application where multiple users can log in at the same time.
I have a JSP where a user is presented with a list of executable items.It is quite possible that at the same time more that one user tries to execute the same item.I want to disable this. i.e at a time only one user should be able to execute the item.
Currently what i can think of is putting an extra column in the database...saying that this item is locked and you cannot access it until unlocked.But then this would involve a round trip to database.I want to avoid it, and do some coding in java code itself.
But i dont know how to proceed.
Any Help......

sorry for the misdirection :(
yes..try using the synchronizing for the run process for of the item in the action class.
I shall try to provide you with the code changes, if can you please provide the back end code doing the job u said

Return only one record at a time

I am new to crystal reports so any help would be appreciated. I have a .net app that is a order processing system. When the user is in a record, they want to be able to click on a button an open a crystal report showing only that orders details. I created a crystal report that has the following fields:
Order ID, Product ID, Unit Price, Sell Price, Hours.
The Order ID is the primary key in the database. The report runs fine when clicking the report button in the app, but returns the details for every order in the database. We just need the details of the order that the user is processing. How do I setup the report to only show that order's details? I am using VB 2005 and Crystal v9.

Brian,
Thank you for all your help. I have been able to setup the report to return only one record at a time. In my app, when I click the report button the PDF opens perfectly with only one record. However, when I go to another record and open the PDF it returns the information from the record id that was set as the default parameter value (crReportDocument.SetParameterValue("Orders", 67). How do I get it to return the report for a different record? Here is the code I'm using. I think I'm really close with your suggestions but I'm just missing one step.
#Region "CrystalReport"
     ''' <summary>
     '''Override the CrystalReportButton_Click and call DisplayReportAsPDF_CrystalReportButton function

      Dim crReportDocument As CrystalDecisions.CrystalReports.Engine.ReportDocument = New CrystalDecisions.CrystalReports.Engine.ReportDocument
      Dim fileName As String = "test.rpt"
      Try
          If fileName.Substring(1).StartsWith(":\") Then
          crReportDocument.Load(fileName)
      Else
          crReportDocument.Load(Me.Page.MapPath(fileName))
      End If
      Catch ex As Exception
          Dim errMsg As String = ex.Message.Replace(Chr(13).ToString(), "").Replace(Chr(10).ToString(), "")

           paramValue.Value = "67"
           crReportDocument.SetParameterValue("Orders", 67)
DisplayReportAsPDF_CrystalReportButton(crReportDocument)
      Catch ex As Exception
          Dim errMsg As String = ex.Message.Replace(Chr(13).ToString(), "").Replace(Chr(10).ToString(), "")

Only if you have more than one device running FaceTime at your end.

Restrict program access ( only three user at a time)

Hi
I want to restrict the program only two users at a time ( with out using authorization object ).
Thanks & Regards,
K.Gunasekar.

Just an idea:
create a table with one column to store the userid. Each time the program ist started, you execute a SELECT COUNT( * ) on that table and EXIT from your program as soon as the table contains more that 2 entries. In case the table does not contain more than two entries, you can proceed after adding the SY-UNAME to that table. At the end of the prgram you have to delete SY-UNAME from that table.

Only one user at a time
