Architectural Help - Converting Single-User DB to Multi-User

I have a single-user database running in Java 1.4. I want to convert it to a multi-user database targeted at really small (no way they can buy Oracle) groups. I have a lot of expertise in the old way (file/record locking, avoiding deadly embrace, etc.) but don't think this is right for Java.
What would be a good Java architecture for such a small DBMS? Initially it would be fine to just run a server on a network, tho longer-term it would be great if the solution extended to a remote server on the net. J2EE is not in the cards unless its absolutely required.

Thanks, warnerja.
Here's the issue. The user is viewing a list of names (customers or whatever). Names are physically stored in the order entered; logically viewed sorted on last name, then first. The user drags the elevator car two thirds of the way down. Now what?
Using SQL-based anything, you're pretty much forced to query the table for the whole result set; keep it in memory and then scroll off that. Suppose you have lots of names - 100K or more. This goes dead slow. Worse, in real applications your names will be inner-joined to maybe several other tables so the problem really multiplies.
See MS Access for a good example of how bad this can be. I've got one where the user clicks the down arrow on a combo box and then waits two minutes (actual, measured with my own watch, wait time) for the list to appear. Ugh.
I've created an indexing method I call the b++tree, which makes it perfectly simple to respond to that user action: goto( 66000 ); getNext( 20 ). If my calculations are correct, that goto() should happen in a single disk read and about ten millis.

How to make extension available for all users in a multi user environment

Hi,
In a multi-user environment, a user install a dreamweaver extension,but just the user who install the extension can use it.
Is there a way that administrator install the extension and make this extension available for other users in multi-user environment(e.g. the Windows 7)
Thanks

Dreamweaver had this capability many releases ago, but it has been dropped, so it's no longer available.

User Settings in Multi-user setup?

We are using two new CS5 editors in our news department. We set the machines up on our Domain partly for being able to use NTFS permissions and because our IT department hates stand alone machines.
The issue we are having is that each person logs in as a Domain User which give similar rights as a local user would have. The editor seems to work fine and we don't seem to have any problems with doing this other than each user must setup about 15 settings for the first time.
They have to change the location of where the project is created to the 500 GB E:\ drive that we have shared on the network (this is for being able to copy and entire project from one editor to the other), then they have to change the DV-NTSC preset for correct audio tracks and then change the General tab settings for Playback through DV Realtime Settings (why is this no longer the default, doesn't anyone still use tape??). Then they save a preset. After that the preset will give the correct audio and sequence settings except the "Playback Settings" does not seem to track from one project to the next.
Then they have to change the source channel mapping to Mono so the two tracks we record in the field, Interview/standup on track 1 and Natural sound on track two don't come in as stereo audio. (this one seems to stay for new projects under that user)
Then they have to change the audio hardware to enable the "line in" for recording tracks from our mixer.
PHEW!!!, as you can see this is a time consuming annoying issue to have every user have to do this.
Is there a way to make some of these settings the default for any user that uses the PC? I don't want to go back to a shared project setup like we had under Avid as it caused a lot of issues with people deleting other peoples stuff.
Any idea's on making these settings stick would be great, Do I need to allow "Domain Users" full write acces to the Premiere Program Files directory?
Thank you,

The main reason for the separate accounts is for allowing each user to have a folder in the E:\ Drive on each editor will be the 1 TB Scratch Drive. These system are only going to be doing DV video for now and will use only basic edits for News packages and VO/SOT's and such. Nothing complicated unless they want to. When users leave every two years (Market 195) we can just delete the user and their folder to clear them out, which gets rid of all the garbage people seem to leave on the desktop.
We have two editors and a common problem with them being stand alone (as they were with the avid systems) is a reporter would go in to Edit 1 and capture or import from camera (nNovia Media Pack) the video for a news story. Then due to having to rush out to get another interview or breaking news they would leave for a while. When they get back there is another user in that bay using it for the next 30 minutes to an hour and so that reporter is forced for time issues to re-capture the same content into Edit 2. This causes wasted time and frustration.
Other stations in our company use a server with large amounts of storage, each user has a folder on that server with all their content. Because you can not edit across the network drives due to latency issues, they copy the Project folder with all their captured clips and files to the local drive of the editor, and go to work editing. Then after working on that project for a while they copy it back to the server that is Backed up and has many TB of storage.
We can't afford to build that server now so I am settling for them to work on each editors Local 1 TB Scratch Disk in a Folder called "Edit 1 Projects"
Then when a user logs into that folder and creates a Sub Folder with their name, e.g. "Sam Johnson" that becomes their folder. Then I am having them create individual project folders under that, e.g. "School graduation VO", "Police shooting PKG". Because that user "Sam Johnson" created the folder he has full rights to it by using the "Creator Owner" NTFS permission I set on the Parent Folder to propagate to the child folders. All other Domain Users can read and use other peoples video, but they do not get "Modify" rights so no user can delete other users stuff. (Another issue we had problems with on the old editor) Only and Admin or in our case the news director can delete stuff.
The plan behind all of this is the reporter would be able to, in the same scenario I outlined above, navigate the network to the shared drive of the other editor and copy/move the subfolder they need over the network. After the copy (which includes the captured files and project file) they could open that project and keep working. With Gigabit speed this should not take long for smaller projects.
I haven't tested this other than it is similar to the Benchmark project I downloaded as a Zip. When I extracted that, I was able to open it as all the source files were included. I am sure there would be issues when the project/files gets so large that the time to copy is as long as re-importing from the tape/camera.
Another benefit of this is users can navigate their projects on the two editors from their desk computer in the newsroom. With a bit of training they will be able to delete the .avi files they no longer need. Due to the video being the largest files, they can easily do cleanup without going into the bay at all. If they want to keep a great clip of B-Roll they shot, they can burn a Data DVD from their desk. All of this is possible being on the domain and having user rights passed from one machine to another through their network login.
If anyone knows of a major flaw to my idea I am not thinking of let me know,
Thanks

Error d124 Multi user calendar

Hello,
we moved all of our users from one PO to another, both GW2012SP2. When the users now open their multi user calendar they get the error "d124".
When i open the multi-user list in a users mailbox there are entries from the old po an the new po. I tried to remove the old entries by click the Name, click Remove User, click OK to save. When i re-open the list, the removed users dont appear. Now i closed the Client, start it again and all of the removed users are shown up again in the multi-user list...
Does anyone have an idea how to remove the user in the multi-user list permamently? Or have any GW Check options to solve this?
kind regards
Benjamin

Moving in every sense of the term always leaves some loose ends like
this. This is why as much as possible we like to move POs and not the
users if we can avoid it. Basically some of the connectsions betweek
users broke because a bunch of them are still looking at the old PO, so
we need to work through those connections and fix them.

In looking this up I found I had a user in my list that was no longer in
the system and I had the same behaviour in trying to deal with it. I
realized that this was only the users I have proxied into, so I went into
my proxy list, removed the offending user, and after a restart the
problem went away. So how many of these do you need to deal with?
Before we look at the specialized GWchecks, make sure you are running a
regular set of them and checking the resulting outputs for any errors
that might point you to parts of the cleanup.
http://www.konecnyad.ca/andyk/gwlogs.htm
Running through the TopDown rebuild (TID 3347260 at
https://www.novell.com/support/kb/doc.php?id=3347260) and selecting the
Rebuild Indexes after doing the other parts at those levels may help.
Afterwards an Analyze/Fix of Structure & Index would be useful, checking
the results to see if it reports problems. If there are such problems,
rerun again to see that they are gone.

Sendmail dependency for multi-user milestone

I am currently setting up a CommuniGate mailserver on a Solaris 10 box . Starting the new service is hampered by sendmail running on the smtp port.
My question regards disabling sendmail services so that CommuniGate can do its own thing. The sendmail service is shown as a dependency for the multi-user milestone:

I've read the sections on dependency groupings (i.e. optional_all/none) but I'm still confused regarding the real links between services.

Set Database Back to Multi User from Single User

I am using SharePoint Services 3.0 (SP1) with default configuration options, which installs the Microsoft##SSEE instance of SQL to my local C:\ drive.
While attempting to relocate the files to another drive, I set one of the databases (as recommended) to Single User by using the SQL Server Management Express tool.
I cannot now reset that database to Multi User, even by executing the query
exec sp_dboption 'database_name', 'single user', ''FALSE'
again by using the Management Express Tool.
Can someone please help, in plain english???? Thanks

I have similar issue.
I have took backup of WSUS (Windows Server 2002 R2) Windows internal database using SQL Server 2008 Management Studio and restored on Windows Server 2012 R2 Server.
Now SUSDB database was in Single User mode. I have tried ALTER DATABASE <<Database Name>> SET MULTI_USER WITH NO_WAIT and i'm getting blow error.
Msg 5069, Level 16, State 1, Line 1
ALTER DATABASE statement failed.
How i can change it Multi User?

Change single user to multi user

Hi,
I put the database ABC in single user mode through SSMS, now when I am changing back it to multi user, I get below error
Msg 1205, Level 13, State 68, Line 1
Transaction (Process ID 127) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
Msg 5069, Level 16, State 1, Line 1
ALTER DATABASE statement failed.
127 is my own session.
Please help me

Hi,
I restarted the database and was able to get rid of deadlock , but I am still confused how was the deadlock when no other session was in the database, there were other connections to master database.
Also let me know how can I check and remove the deadlock?
REgards
Probably taking it Offline would have worked i assume.Deadlock is not possible if only one transaction is there multiple transaction are required/involved .As suggested by article provided by me there must be some other request coming from application or
from other users who have logged in .Did you searched ? tried using DMV to find out ?
If you say' yes I did but did not find anything ', I would not believe you.regarding how to resolve deadlock please search on net you will get many good articles.without seeing deadlock graph one cannot comment.
Also its brave decision to take database single user ,before we do we make sure app is not accessing DB,no other job is running which is accessing DB. Any background process is using DB should be either killed or rolled back then we proceed with keeping
DB in single user mode.

Several users on a single file issue: Hosting a multi user Quickbooks file on the WD EX4

Hello everyone. This is going to sound like a super specific third party support issue - but there are some universal things going on here that may help others regarding multiple users of individual files on the EX4. My company houses client and billing files on the EX4. It's all been well and good until we recently allowed multi-user access to our Quickbooks company file. Of course the goal is to have multiple employees working on the file at the same time from different computers. We purchased licenses for each - everything is on the up and up. Whereas I could access the company file on the EX4 with no problems on my computer as a single user, now as soon as I turn on multiuser mode in QB to allow others to access the file on the EX4, the file becomes inaccessible. What do you guys think is happening where one user access to a file on the EX4 is fine, but multiuser access causes the file to be inaccessible? How do you fix it? Other thoughts, there doesn't seem to be a limitation on the EX4 relating to multiple people accessing the same file - streaming the same song for example. So why would a billing database file be any different? Especially when the licenses and program allow that access. Here's more info, if I host the file on my desktop computer everyone can access it in multiuser mode over the network. The limitation is the WD EX4. What do you think is going on? (I'd appreciate any insight as I am talking to both tech support teams, QB and WD, this week.)

Thank you so much for your reply. The error shows up when one switches to multi-user mode. It states: Error H101, H202, H303, or H505: when opening your company file When you open a company file in multi-user mode, you see an error:You're trying to work with a company file located on another computer, and this copy of QuickBooks can't reach the server on that computer (H202).You're trying to work with a company file located on another computer, and that computer needs additional installation and setup. (H101, H303, and H505).It appears that the QuickBooks software on computer [server name] is set up to allow shared connections to the company file, but the QuickBooks software on your computer is unable to communicate with it. (H202).Most often it's an H202 error which suggests that the program can't reach the server on that computer (NAS location). Why would the NAS location become invisible / unreachable once multi-user mode is on? I really appreciate your expert brainstorm and ideas.

I'm not sure exactly what you are asking. InDesign files can be edited by only a single user at one time, but any user can open a file not already in use.

UPK11 - multi-user environment - manage author permissions - help

We are configuring our UPK 11 multi-user environment.
As we have it set, the "everyone" group has modify access to all folders.
I would like to have a few admins have modify access to the system folder and everyone else be read only.
Here's my dilemma -
My admin profile is also a part of the everyone group - so if I set the permissions on the everyone group to read only, that effects the admin login as well.
The documentation says that if I set up an author with explicit folder permissions, that they are not included in the everyone group, but everytime I try, they are added (irrevocably) to the everyone group before I can even assign an explicit permission.
I tried to set the everyone group to read only and nearly hobbled my admin account.
Can someone who has managed authors in a UPK 11 multii-user environment send out some tips?
I'm not understanding the documentation well enough to make headway.
[email protected]

Hi Paul,
I recently performed an implementation of UPK 11 at a client and had to show one of their employees how to administer the security surrounding profiles and authors.
The group "Everyone" is default, and each person will belong to that group. It seems that when a person is assigned to another group/with author-specific permissions, it will override that which is set to the "Everyone" group.
What I normally suggest (and implement) is that you modularise your security (separate the authors into their respective departments), and then create those departments as groups, and then assign permissions as required. Lets use an example - it assumes you are logged in as an admin user:
I create 3 folders (where 4 and 5 are defaults):
1. HR
2. FIN
3. CS
4. Administrators
5. Everyone
Each author is defaulted to number 5, and all administrators should be included in group 4.
Now the goal is to prevent HR and FIN from modifying CS, and vice-versa for the other two groups.
You will see in your library that the root is defined as "/". Firstly, ensure that the Administrators group has Modify access to this folder (Administration --> Manage Groups --> Permissions). I think you need to click on edit, then click on the "Add" button (under permissions), and choose the root folder "/" - ensure it has modify - by default this value should already exist. This now ensures that the security is filtered down to all sub-ordinate folders that exist under the root folder - you do not need to manually assign "modify" permissions to each folder for the Administrator group, as you have already done so at root level.
You will also notice that there is a "Members/Users" tab (can't remember off the top of my head which), and this allows you to select the profiles/authors that have Administrator group priviledges - ensure the correct users are selected.
I normally leave the "Everyone" group as it is - do this for now, ensure everyone is included in it, and only modify after you have implemented and tested your security structure if needs be - normally the other group permissions override the "Everyone" group permissions.
Next step is to assign department specific permissions to the 3 folders we created. Navigate to Administration --> Manage Groups, and ensure that you begin by editing the first department group (HR) - create the group if not already done, then edit (little pencil logo). You would like all HR users to have full modify access to their folder only, but they must not be able to mess around with the other two departments or the "System", "Getting started with UPK" and "/" folders. Under permissions, click on the Add button, and ensure that the folder "HR" has modify priviledge. Add the remaining 4 folders (CS, FIN, System, Getting started with UPK), and assign either Read or Read/View permission - this will ensure all other folders cannot be modified by HR users. Add the relevant HR users to the group under the "Members/Users" tab.
Apply the same for FIN and CS respectively.
Now you could get to a point where you may need cross-departmental access for a few users (FIN may need to access some HR content). I recommed that you do this on the user level, and not the group level, as you will limit who can access other departments. Navigate to Administration --> Manage Authors. Click on the specific user that will require access to another department. Edit his profile and under the permissions tab, ensure that he has required access to the other department folder (or sub-folders only) by adding and assigning the priveledge. This should ovveride the group security set for that specific department - but only for this user!
Test by attempting to create content in an un-authorised folder (when logged in as a normal user). Test admin account by creating content in each folder. If it works - you will no longer need to modify "Everyone", as your permissions are defined under the other groups. I hope this all makes sense?
Thats it in a nutshell really.
I hope that this helps, and feel free to get back to me if you are still unsure?
Regards,
Greig

Multi-user login screen help

I am looking into an application front end with NI hardware controlling a temp process. The fun thing is the multi-user login that controls the screens you can access. Does anyone know of a good way to accomplish this?

I've attached it below. Here is the description from the webpage:
This VI uses Key Down events to control the user login process. The user must enter the username and password using only upper and lowercase letters. If the user enters other characters, the VI displays an error message and discards the event. The VI also converts all uppercase letters to lowercase before verifying the username and password in a subVI. "Number of loops" displays the number of times the While Loop iterates, which is the number of times an event occurs on the front panel.

Diff bet multi user and single user installation

Hi,
what is the diff betweeen single user and multi user installation,please let me know advantages and disadvantages also .
Regards

Hi,
what is the diff betweeen single user and multi user installationSingle user installation is having one user who owns all the application/database tier files. When you do an installation, you run RapidWiz as this user.
Multi-user installation is having two different users (applmgr user who owns the application tier files, and oracle user who owns the database tier files). When you do the installation, you run RapidWiz as root user.
On Windows, you cannot have multi-user installation. So, the above is valid on Unix/Linux.
More details can be found in the Concept manual --> http://www.oracle.com/technology/documentation/applications.html
please let me know advantages and disadvantages also .I always prefer multi-user installation as you just source the application/env file in the user's profile (in the applmgr/oracle profile) and the file is sourced once you login as that user. For single user installation, you will have to be sure that you source the proper env file manually each time you want to switch between the application and the database (just imagine if you try to shutdown/startup the database after sourcing the application env file, or trying to use any database executable file like export/import/sqlplus ..etc, you will end up using the application tier executable files).

RVM Multi-User Installation Help

I am trying to follow this wiki guide on installing RVM for Multi-Users.
https://wiki.archlinux.org/index.php/RV … stallation
The problem is after I add myself to the rvm group using
$ sudo usermod -a -G rvm <user>
Then I log out and back in, but there is no ~/.bash_login file.
The next step is to change the line
[ [ -s $HOME/.rvm/scripts/rvm ] ] && source $HOME/.rvm/scripts/rvm to the system-wide location changing $HOME to /usr/local/
but I can't because there is no ~/.bash_login file.

Reread the page again, the instructions are quite clear:
After the script has finished, then add the following line to the end of your ~/.bash_login or ~/.bashrc (or ~/.zprofile or whatever)
You should also read the bash page to get an understanding of the various files in the shell initialization process:

How to send one email to multi-users using JavaMail ?

I am using JavaMail API. I am working in "sending emails to users", I had already tested "one email to one user" and got success but when tried to send one email to multi-users then I failed to do that?
Can anyone help me to do this?
I have used the below code to send to multi-user:
Address[] toAddr = {new InternetAddress(_to),new InternetAddress (to2)};
msg.addRecipients(Message.RecipientType.TO, toAddr);
But it is static only 2 users. I want to send to multi-users dynamically taking datas from database.
I have tried by using below code but it doesn't work.....
InternetAddress[] emails;
while (resultset.next()) {
temp = resultset.getString(1);
emails.setAddress(temp);
i++;
Address[] toAddr = emails;
msg.addRecipients(Message.RecipientType.TO, toAddr);
Thank you in advance...
-ritesh

I think you're confused about some basic Java programming techniques.
There are two obvious ways to do this.
1. Call the addRecipient method in a loop.
2. Collect all the recipients in a List, convert it to an array, and call addRecipients.

File structure and Multi-user access/control

Hi All
Currently evaluating RH. Our plan is to use RH HTML with RoboServer and either SourceSafe or Team Foundation for source control. We will be producing the "printed" manual (PDF) and publishing online help (hopefully html via RH server) from the single source layout
Given that we will edit content in RH's XHTML editor, I'm not clear on when we should create new files or the granularity of multi-user access. We have 17 apps and I plan to use a master project and merging (because we need to link to related topics in other apps).
I'm really not sure what should constitute a file in RH. First off, is access controlled at the file level?
I want to have multiple authors editing the same manual at the same time, so do I need to break the manual into multiple small files (currently it's a single word doc)?
If I do break it into multiple files, what's the best approach: 1 file per topic (or is this a requirement)?
Finally, when I come to generate the PDF, will the files be combined. (i.e. can I have different page-breaks than I have in the RH project)?
Any pointers greatly appreciated
Regards
Mark

Hi,
First off, is access controlled at the file level?
Not sure what you mean by that. In source control, you can check in/out ever file independent. Sometimes dependent files will be automatically checked out, for instance images used in the css when you check out the style sheet.
I want to have multiple authors editing the same manual at the same time, so do I need to break the manual into multiple small files (currently it's a single word doc)?
That be the idea. Anyway, it's not a good idea to have an entire RoboHelp project in a single topic. You probably want to cut up your contents into the small chunck: topics.
If I do break it into multiple files, what's the best approach: 1 file per topic (or is this a requirement)?
In RoboHelp a topic is a HTML file. RoboHelp doesn't force you to split up content into one or more topics. If you are creating help for the web, you want the information to be organized in relatively small chunck so users can quickly scan through it.
Finally, when I come to generate the PDF, will the files be combined. (i.e. can I have different page-breaks than I have in the RH project)?
Not sure what you mean by page breaks. As RoboHelp creates HTML files, there are no page breaks such as in paper manuals. When you create a PDF, you combine the topics you need into a single document.
If a PDF is required for you, you may want to consider not using RoboHelp for your sources. A PDF created by RoboHelp is useful for internal use, but it never seems to get good enough to give to customers. Personally, when a PDF version of a manual is required, I create the manual in FrameMaker and link or import the book into RoboHelp. You can also link Word documents, so you may want to play around with that before deciding whether to use Word, RoboHelp or FrameMaker for your source.
