Two environments to the same physical location

May I open two environments (one readonly and one with write access) to the same physical location on the disk?
I think to use the one with readonly access as consumer of data but the second as manager and provider of data.
Both environments will be established by different processes (applications) or VMs.
Is there any special order (sequence) to open them or there is not any.
Thanks.

Hi,
First, please see this documentation about read-only processes:
http://www.oracle.com/technology/documentation/berkeley-db/je/GettingStartedGuide/multiprocess.html
Read-only processes are very limited because changes made by the writer process are not automatically seen by the reader process, as described in the 3rd bullet of the documentation. To get around this limitation, replication can be used. Replica processes do see changes made by the writer process. For information on replication see:
http://www.oracle.com/technology/documentation/berkeley-db/je/ReplicationGuide/index.html

Duplicate entries in iTunes display, but both entries point to the same physical location.

I've seen lots of discussion about how to remove duplicate copies of the same song, but my issue is different.
iTunes has duplicate entries in its database, but if I do show in finder, then both entries point to the same physical location.
If I delete one entry, then the other entry becomes unusable.
Any idea how I could clean this up? Its annoying because if I select an album to play, then each song gets played twice.

@zoo_bink I too have exactly the same issue however it's not affecting all my files.
One solution, which I'm contemplating, is to backup the iTunes Media folder, delete files, uninstall/reinstall iTunes then re-import the files. The issue may have arisen during initial import. (I'm not sure at this stage if Apple allow iTunes to be uninstalled.)
iTunes music collection is showing 58.95GB versus 57.11GB in Finder so it's not a massive deal but annoying nonetheless as deleting entries isn't an option.
Any suggestions welcome.

I am unable to connect my ipad to the internet via wifi, when asked for my password I get message "unable toI ge join network" however my laptop is able to access the internet using similar procedures and in the same physical location.?

What router are you using? make/model/version
What security type are you using? If it is WEP then symbolic (non hex) keys may be converted to hex in different ways by different operating systems. Is your laptop a Windows PC?
If you are using WEP then drop it and move to WPA2. WEP has been deprecated by the WiFi alliance since 2004 as insecure (it can be hacked in seconds).

Two contexts sharing the same physical interface

Hi,
I have been looking for a configuration guide on how to set up one physical trunked interface to be shared between two contexts. I am sure I am just using the wrong search words but have as of yet been unable to find anything on this. Anyone able to provide a link please?
Thanks

Hi,
I have not linked (or have the need to) 3 Security Contexts before but I would imagine you could modify the above configuration a bit to achieve that also

I am not sure if this would be the way but that is how I imagined at the moment.
The setup should look something like this
Totally different matter would there be a better way to achieve the same as above

Sharing iTunes libraries from two accounts on the same physical box

I have two users set up for fast user switching on a single box. both users are active. each has its own copy of iTunes running, each with its own library, each set up to share. the firewall has iTunes sharing enabled.
from a separate copy of iTunes on a different box, I can see both libraries posted for sharing. if I try to open one of them (belonging to the administrator account), sharing works as advertised. if I try to open the other, loading times out, and the share fails with error code 3359.
is the problem that only one copy of iTunes on a physical box can be shared at a time? or is there some other configuration issue I've not taken account of?
thanks
G5 Mac OS X (10.4.5) iTunes 6.0.3

thanks for your response.
if you've submitted a feature request, it may be a lost cause for the moment. what I find, however, is that if both are logged on and active, it's the one that started first that's available.
regards.

How do I share one itunes account between two users on the same computer

How do I share one itunes account between two users on the same computer without taking up twice as much space on my hard drive?

You would need to move the itunes folder to a location that both users have permissions to access such as the Shared folder or any folder on the root level of the macintosh HD.
You can find instructions here http://support.apple.com/kb/HT1203 This method allows you to share the content without sharing the same library.

Sharing iTunes Library with two users on the same computer

I have all of my music stored on a external hard drive.
Both users on the same computer have the iTunes music location folder as the external hard drive. How do I see music added in one persons log-in? For example: I just purchased two albums under one log-in. The second log in can not see that music unless I manually add it.
Both Libraries point to the same file location.
I have over 40GB of music and I am looking for a way to manage my music files more effectively and I want to make sure that both log-ins have the same music.
I followed the instructions in article HT1203 from the apple support site.

The reason you are having this issue is because you have a shared library but private databases. What you have on the external drive is the collection of media files (library) that each account is set up to access as the source for media. What you have not done is set up a shared iTunes database, so each user accesses the same library differently.
When each user opens iTunes, iTunes access the database on their account (~/Music/iTunes/iTunes Library). Therefore, their settings, views, playlists, etc., are private. When they add songs to their library only their database file is updated to reflect those additions; simply having files in the music folder does not mean that iTunes will recognize them, hence the reason iTunes asked you if you want to move the file to the trash when you delete it from your library.
The confusion here is the double use of the term library. The contents of you music folder most definitely constitutes your media library, as it is the collection of your media files. What you see as your library in iTunes is not your library but, for the most part, the content stored in a database table maintained by iTunes in the iTunes Library file in your iTunes folder. iTunes does not access your actual media files unless it is absolutely necessary. The general assumption is that what is shown in your iTunes “library” will actually mirror what is in your music folder.
So the missing step in your setup would be to switch to the account that has the most current iTunes library—that is the one reflects the actual contents of your music folder as of now—and follow this procedure.
1. Quit iTunes.
2. Move the iTunes folder to the Shared folder (./Users/Shared).
3. Launch iTunes, but immediately hold the option key to invoke the Choose Library window.
4. Select the database (iTunes Library file) now located in the shared folder.
5. If you do not see your content, go to iTunes’ preferences and reset the location of the music folder to the external drive.
6. In the other accounts, re-launch iTunes and change the library according to steps 3 and 4.
Now all users will have access to the same iTunes database as well as the shared library. The downside of this is that each user will have full access privileges. If you have iTunes 8, then to avoid the disadvantages that come with this type of set up, see [this thread|http://forums.macworld.com/thread/105366?tstart=0] over at Macworld.

How do I separate two movies on the same timeline?

I'm using Premiere Elements 11 but have not used it for a while so I've forgotten much of what I've learned. So here is my question: I have two movies on the same timeline. How do I separate them. In other words, how can I move one over on the timeline so it will not confuse my editing of the other one? But better yet - how can I just take one movie off the time line completely and edit it later as a separate movie. I really have four short movies - one minute long. I'd like to edit them separately, with a new file name. I don't know how to do this anymore.

Tommyvincent
I have been doing some homework on the questions that you raised in this thread.
Observations....
1.
After you import a video into Project Assets, you can right click it, select Rename. That file when dragged to the Timeline will have the new name.
But...
If you import a video into Project Assets, drag it to the Timeline, right click the Timeline clip, select Rename from the pop up, then the Timeline file will be renamed but not its thumbnail in Project Assets. You would have rename that Project Asset thumbnail to match if you wanted to. But, these renamed files still trace back to the original with its original file name at its hard drive save location.
2.
About getting off your Timeline...one way would be to export the clip selectively if it were in group of clips on the Timeline. Two requirements for that
a. In Edit area, set the gray tabs of the Work Area Bar to span just the segment to be exported
and
b. In the export area, have a check mark next to "Share Work Area Bar Only" option.
3.
If you brought a clip into Project Assets, double clicked it to open its Preview Window, you could trim the clip with the Set In and Set Out points and create "subclips" with new names in Project Assets. These "subclips" would be part of that project's media that could be dragged to the Timeline when needed.
Please review and determine if any of the above is going in the right direction for what you want to do.
Thank you.

How do i create one source file that feeds two users on the same pro book?

how do i create one source file/folder of photos that feeds two users on the same pro book?

Well you can do exactly the same with a folder of photos, just put in the Users/Shared folder.
Iphoto is a mite more complex than this. It's a database and so there's a bit more involved.
For iPhoto 09 (version 8.0.2) and later:
What you mean by 'share'.
If you want the other user to be able to see the pics, but not add to, change or alter your library, then enable Sharing in your iPhoto (Preferences -> Sharing), leave iPhoto running and use Fast User Switching to open the other account. In that account, enable 'Look For Shared Libraries'. Your Library will appear in the other source pane.
Any user can drag a pic from the Shared Library to their own in the iPhoto Window.
Remember iPhoto must be running in both accounts for this to work.
If you want the other user to have the same access to the library as you: to be able to add, edit, organise, keyword etc.
Quit iPhoto in both accounts. Move the Library to the Users / Shared Folder
(You can also use an external HD set to ignore permissions, a Disk Image or even partition your Hard Disk.)
In each account in turn: Double click on the Library to open it. (You may be asked to repair the Library Permissions.) From that point on, this will be the default library location. Both accounts will have full access to the library, in fact, both accounts will 'own' it.
However, there is a catch with this system and it is a significant one. iPhoto is not a multi-user app., it does not have the code to negotiate two users simultaneously writing to the database, and trying will cause db corruption. So only one user at a time, and back up, back up back up.

How to fix the "Two computers using the same IP address" issue on the airport express

I just bought an airport express and got dsl at my apartment, and I haven't been able to set up the wireless connection. My DSL works just fine but whenever I hook up the AX I get an error message saying that there are two computers using the same IP address on the network, but I only have one computer.
I know this is probably a simple fix, but I've never had this issue when I set up the Extreme at my parents house and I haven't been able to find a thread on this.
As of right now I have it set to Factory settings.
Help please!

This modem was designed to connect directly to a computer and you are trying to connect it to a router.
Unfortunately, this is not a simple fix as both the modem and your AirPort Express will need to be configured differently to work together correctly.
Connect the modem directly to your computer.
Open up your browser and type the default IP address for the modem into the address bar. Check your documentation on the modem but it is likely 192.168.1.254
That will bring up the configuration page for the modem.
You may need to enter the modem access code which is on a label on the back or bottom of the device
Look for an Advanced tab, then look for a tab labeled something like PPP Location
Right now, you will see that "PPP is on the modem"
Chance that to "PPP is on the computer or router"
Click to save your new settings and the modem will restart
If you ever need to get the modem back to its original settings, you will need to hold in the reset button on the back of the modem for 5-6 seconds and then enter in the default IP address to be able to access the settings on the modem
Connect the modem to the AirPort Express with an Ethernet cable
Open AirPort Utility on your Mac and click Continue to follow the guided setup to "Create a wireless network"
You may be asked to "switch" networks when you do this. You want to switch
Select the "Connect Using PPPoe" option when it appears
Enter your user name and password with your provider. Leave the Service Name area blank. You want to always stay connected if you see that option
Continue to follow the guided setup and Update to save settings
Pull the power cord from the modem, wait a moment, then restart the modem
Log on to the wireless network that you created during the setup and you should have an Internet connection

Can one installation of SSIS be shared by multiple instances on the same physical box?

Hello everyone,
I hope I'm posting this question on the correct forum.
We are short on money this year and we decided to purchase one physical system to represent Development and QA.
I am designing an architecture around my systems where I would have a two SQL Server Instances (2014, Enterprise Ed), one for each environment:
DVSV-ODS01\DEV
DVSV-ODS01\QA
The only possible problem is SSIS, which I cannot have multiple installations of SSIS on the same box.
Is it possible to have the SSIS service serving the two SQL Server instances installed on the same physical box?
Thanks for your help.

Not on the same physical box, but you can go with running say the QA environment on a Virtual Machine.
E.g. the very free VirtualBox should do it. And then you can install two SSIS instances.
You can even access them simultaneously this way.

Two classes have the same XML type name??? Please, help...

Hello!
I have a simple web service class. I generated the ws server-side classes using wsgen.
I created a jar file from the generated code.
Then :
Endpoint endPoint = Endpoint.create(
new WebServicesUnitImpl()
String wsFinalName = "http://localhost:9999/akarmi";
endPoint.publish( wsFinalName );
The web service started fine.
Then called wsimport, and the generated classes have been placed into a jar file.
Then called the code like this:
WebServicesUnitImplService service = new WebServicesUnitImplService();
WebServicesUnitImpl unit = service.getWebServicesUnitImplPort();
unit.serviceXXX();
but the code doesn't work at all, resulting this error message:
Two classes have the same XML type name "{http://ws.components.core.ilogique.vii.com/}getMessages". Use @XmlType.name and @XmlType.namespace to assign different names to them.
     this problem is related to the following location:

I have this error report on all generated class file! How can i fix this?
What is the main problem? The SE usage? I copied the lates jax-ws jars into endorsed lib resulting the same.
Any help is appreciate.

Oracle XE on multiple virtual machines on the same physical machine?

hi,
does oracle's licensing for 11g express edition prohibit running XE databases on multiple virtual machines on the same physical machine? if not, does the machine have to be "hard partitioned" per oracle specifications (link below) to make it legal?
http://www.oracle.com/us/corporate/pricing/partitioning-070609.pdf
i found a similar question regarding 10g express edition in the forum (link below), but it doesn't seem like the question was ever definitively answered.
Oracle XE on multiple virtual machines on the same physical machine?
thanks

I thought until I just checked that this was a clear cut no in that it specifies 'a single server'. Now I'm not sure as 'server' is an amibuous term. I at least know that as soon as you start giving developers access to theor own XE instance for dev/testing that there are many VM environments where you can't really know what physical macine your VM is running on to actually be able to tell if you had multiple XE instances running on a single 'Physical' server. I'm not sure the question has been answered by Oracle though.

Use two interfaces on the same network

Hello every one,
I actually starting to work on a cisco project. I'm a beginner on networking and cisco technologie.
For my project we use a router 2921.
We got two network:
- Network A: 192.198.0.X / 255.255.255.0 / Gateway 192.198.0.1
- Network B: 162.168.0.X / 255.255.0.0 / Gateway 162.168.0.1
Each network use switch, Switch A (connecting to network A) is connected to interface G0/0.
And Switch B (connecting to network B) is connected to interface G0/1.
Router well configured as:
- G0/0: ip address 192.198.0.1 255.255.255.0 (network A)
- G0/1: ip address 162.168.0.1 255.255.0.0 (network B)
Every think working fine.
The problem is with this one, we need to connect a computer on G0/2. This computer is configure as network A (192.198.0.10 / 255.255.255.0 and same gateway).
I can't configure G0/2 as 192.198.0.1 255.255.255.0 (network A), cause G0/0 use this adresse.
I can't put this computer on the switch A, my only physical possibilité is to connect him on G0/2.
We just need to use interface G0/0 and G0/2 as a switch on the router with the same gateway (192.198.0.1)
How can i connect this computeur? How can i configure two interfaces on the same network and same gateway?
Thanks you

I would just put the PC on a different network, but if you really want it to be in the same network, you could use IRB to connect two of the interfaces on the router at layer 2.
Here is an example config for IRB:
interface FastEthernet0/0
bridge-group 1
interface FastEthernet0/1
bridge-group 1
bridge irb
interface BVI1
ip address 192.168.0.1 255.255.255.0
bridge 1 route ip
Notice that the physical ports do not have IP addresses on them, the IP for the subnet is on the BVI interface.
