How does TimeMachine determine which backup to link to?

We have 4 Macs, each having a Time Machine backup file on an external Time Capsule.
How does the Time Machine on each Mac know which file on that Time Capsule it links to?
Is it done via the file name, meta-data in the backup file, some other method?
Ideas?
Thanks

Before "you" start an instance you set env variable ORACLE_SID. This identifies an instance. When you go into sqlplus and issue STARTUP, Oracle starts the instance named by the sid. Thus the instance running on the server is controlled by you. This changes as noted below.
If you were using a non-Oracle tool to start instances, such as Veritas, then you would see it start the instance you coded into the tool. It would not randomly pick an instance. It looks in the Veritas config file and sees that you always want instance 1 on this node and instance 2 on that node.
That said, you can make Oracle more random or "grid" like. 10g RAC done Oracle's way likes to bounce around between primary and secondary nodes. To see which instances are running on a node you can "ps -ef | grep pmon". Alternatively, use sqlplus to look in the database: view gv$instance gives you each instance name paired with the name of the host it is currently running on. There is one line of output per instance currently running.

Static Files with same name. How does apex determine which files to serve?

Hello, I'm using apex 4.2.1.00.08 and I cannot figure out how apex manages the static files and cannot find any help in the docs (other that some high level UI description).
The application is serving some file and I cannot find which one it is in any easy way.
I have a workspace where there are several files that have the same name, and I cannot understand how apex figures out which one to serve, and also don't understand what is value of associating a file with an application.
There are files associated with application 0, which don't appear to show up in the "shared components", but can be seen as
SELECT *
FROM wwv_flow_files
WHERE flow_id = 0;
and can apparently only be deleted using "SQL Commands" inside apex.
the URL called is something like
wwv_flow_file_mgr.get_file?p_security_group_id=13498126233076320&p_fname=myfile.css
so apparently the only parameters that matter are the workspace and the file name. The associated application is irrelevant.
apparently files linked to flow_id 0 have precedence over all the other files ...
Thanks for clearing up a bit of "fog" on this issue.

Files associated with an application are referenced using *#APP_IMAGES#*
Files not associated with an application are referenced using *#WORKSPACE_IMAGES#*I referenced with #WORKSPACE_IMAGES#, but now I see that if I use #APP_IMAGES# the URL generated will also contain the application ID. This would help to discriminate between different files with the same name but linked to different applications ...

Do they take precedence over all other files with the same name?
Filename is unique for the given workspace[and application]I disagree. I have multiple files with the same name ... the root of this problem ...
so apparently the only parameters that matter are the workspace and the file name. The associated application is irrelevant.How is your static file referenced??
But not always, try associating an static file with and application and reference it using #APP_IMAGES# instead of #WORKSPACE_IMAGES#

Thanks, but the documentation doesn't give much details ... apparently files referenced with #WORKSPACE_IMAGES# can still resolve to files linked to specific applications ... I would like to understand the actual workflow for the various cases (file references with APP_IMAGES, referenced with WORKSPACE_IMAGES, file associated with the application, with another application, with no application, with application "0" ...).
Also, I find it somewhat misleading that you can have files associate with applications that don't exist anymore (e.g. have been deleted).

How does one determine which version of the runtime installed?

I am trying to distinguish whether or not a particular language version of java 1.4.0 is installed on a certain computer. As you may know, one can download the English language version of the runtime or All languages including English. Is there anyway to easily determine which language version is installed?

How does RAC determine which instance number to run on which node

Good afternoon
I am trying to script a process and I need to identify how RAC decides which node runs which instance. Is it the first one of the pair added to the cluster that runs node 1 or is there some other piece of information that I need to work this out
This is on Redhat Linux with 10.2.0.3 for CRS, ASM and databases
Cheers
Peter

How does DIADEM import TDMS files? How gets every channel his number and groupindex? How can I determine which channel has which groupindex and number?

I store different channels in a TDMS file.
I like to have a time channel at the first position with group index 1 and number 1.
When I read the TDMS file with DIADEM the time channel (Float64) is on a differernt position, and the channels are not sorted alphabetically.
Here are my questions:
How does DIADEM import TDMS files?
How gets every channel his number and groupindex?
How can I determine which channel has which groupindex and number?
Best regards
Joerg

Hi Jörg,
i suppose that you´re programme whose create the *.tdms file is writing on false position. Try to create datas with timechannel on first indes in diadem, then save it and then open it again. you see that all is correct. So please tell me what programm in what version do you use and please attache it here.
Did you use the library for creating *.tdms files like in the link ?
http://zone.ni.com/devzone/cda/tut/p/id/6471
Here you find the gtdms_8.x.zip - when you extract it and opened the *.llb you find vi´s for all functions e.g. writing 2d array of strings to *.tdms file
when you open the subvi´s then you see how created and writing datas/structure to *.tdms files. Because *.tdms is binary you can´t see structure with open it in editor.
When you don´t have Labview you can use the 30 days test of current version 8.5 under following link
german version download link

HT201250 How can I determine which Time Machine backups can be deleted to free space on my backup device?

Time Machine keeps hourly backups for the past 24 hours, daily backups for the past month, and weekly backups.
But are they all incremental or full backups?
How can I determine which can be deleted to free space on my backup device?
Thanks.

Thanks.
So, if TimeMachine only makes one full backup the first time a backup is taken, and then automatically removes backups as space is needed, is there a danger that there can come a point where no single restore point exists?
I find Apple's lack of detail around this topic disappointing. It's such an important thing.
I guess TimeMachine doesn't work quite how I want it too. Seems to be true of so many Apple products!

I have about 5,000 images in a Folder. How can I determine which images are NOT in a Collection?

I have about 5,000 images in a Folder. How can I determine which images are NOT in a Collection?

Create a smart collection with criteria "collection" and "does not contain"; and also with criterion Folder contains (or folder contains all)
That works if you are thinking about a specific named collection.
If you are interested in finding photos that are not in ANY collection, the usual trick is "collection" "does not contain" "a e i o u y"

How can I determine which image was clicked in 3D carousel?

I have been modifying some 3D carousel code that I found in hopes that I can get it such that when image "resolv2.jpg" (or any of my other images) is clicked on at the front of my carousel, it goes to a specific webpage. By just replacing "moveBack(event.target) from the toggler section of the code with "navigateToURL:(newURLRequest('http://google.com'), the target DOES sucessfully go to google when clicked on. However, I want to modify this code by altering the else statement to say something to the effect of "else if event.target (clicked on object) is 'resolv2.jpg' THEN go to google". So essentially, my question is how can I determine which image was clicked? Here is the entire code with the area I was altering bolded:

Your answer may be correct, but I am very much a beginner to actionscript, and I was wondering moreso if it is possible to determine the root/url (i.e. images/resolv2.jpg)? Or even if InteractiveScene3DEvent calls a variable that holds this url? However, specifically, I'm just wondering if the actionscript itself could determine the url in a line of code such as "if object == BitmapFileMaterial("/images/resolv2.jpg"); "? Also, here's a copy of InteractiveScene3DEvent in more detail if you think that will help:
public class InteractiveScene3DEvent extends Event

How can i determin which tab has been clicked??

hi there
how do i determine which one of the tabs in a tabbedPane has been clicked? do i add ActionListener to the tabbedPane or its sub JPanel?

I import them all, it finallly compiled, but I am not sure if they are ok. here is the codes
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
TabbedPane = new JTabbedPane();
TabbedPane.addTab("Easy", easyTab);
TabbedPane.addChangeListener(new ChangeListener()
public void stateChanged( ChangeEvent ce )
Object source = ce.getSource();
if (source == "Easy")
currentTab = "easy";
does it look all right to you?

How can I determine which computer a share is connected to in /Volumes from terminal or a script?

I run a set of virtual machines via Fusion on an iMac that we run automated tests on for our website. There is a folder on each VM called /Automation that is shared.
I have a python script that runs on the host, that will find an open VM, start it up and then mount the VM's /Automation folder. So if there is only 1 VM powered on, the folder shows up in /Volumes as /Volumes/Automation. The problem is when there are 2 or more VM's powered on, because then the shares start being named /Volumes/Automation-1 and Automation-2 etc. So my question is, how can I determine which computer each share belongs to from terminal or a script?
In other words, I'm looking for something like:
/Volumes/Automation = "FirstVirtualMachineName.local"
/Volumes/Automation-1 = "SecondVirtualMachineName.local"
Is there any way to determine which computer a mounted share is connected to? In the past, I've just unmounted all /Automation folders, and then mounted them in a particular order, but that's unreliable and messy in my opinion. If anyone knows a better way, please let me know. Any help is appreciated.
Thanks,

Well I think I have a workable solution. It's not perfect, but I think it will do the trick. I can put a spotlight comment on the folder similar to 'HostName=OSX-Automation-1.local' and can then retrieve that value from our server with the following python snippet:
import subprocess
out,err = subprocess.Popen(['osascript','-e','tell application \"Finder\" to get comment of \"Macintosh HD:Volumes:Automation-1\"'],stdout=subprocess.PIPE, stderr=subprocess.PIPE).communciate()
So I could just loop through each 'Automation*' folder in /Volumes and grab the name from the spotlight attributes on the directories. I don't think I really need to worry about the comments being overwritten, but I may have one of our launch daemons that run on the VM check that spotlight comment once a minute or something to ensure that the correct value is there.
If it ends up not working well in practice, I'm going to give your suggestion about a config script a shot. It would require a little more up front work, but seems as if it would be pretty solid after that.
Thanks again for helping me think it through
