CIFS directory structure

Hi,
I’m curious about something we heard from a Cisco tech a while back. What he said was that the WAAS caches file content but not directory structure. In order to resolve a request for content the request still goes back to the original file server in order to read the directory entry. We have seen instances in the past where it seemed like directories with a large number of files consistently performed worse (even for small files). We had a situation where a single folder was being used to store all of the images from a document management system for an entire year (20,000+ files). That was completely unusable. Even after we prepositioned most of the current year, in many cases, access to these files would time out completely and fail. This did not happen when the processing was all local. When we broke the folder structure down into months rather than years, the performance of the system was improved 100 times over and we’ve had very few complaints about this system (related to network performance) since we did that.
Have either of you seen anything like this? I admit this was an extreme case of poor folder design on our part. Just wondered if the number of files in the directory seems to have anything to do with poor performance.

Anyone who can answer this?

Import statement and directory structure

First of all, sorry for such a long post, I believe part of it is because I am unsure of the concept of importing in Java. Secondly, Thanks to anyone who can ultimately enlighten me to the concept of import. I did ask this question before in the "erorr and error handling" forum, and the people who have helped me there did a great job. But, I believe I require a little more clarification and thus have decided to post here.
Anyhow, my question..
Could someone explain to me the concept of the import statement, or direct me to a webpage with sort of explanation for newbies? For some reason, I am having a hard time grasping the concept.
As I understand it, the import statement in Java, is very similar to the namespace keyword in C. That is to say, import doesn't actually "import" any source code, the way that the #include statement does in C.
So I suppose what my question is, say I have a java class file like below:
//filename: sentence.java
//located: c:\school\csc365
package csc365;
class sentence
//some variables here..
//some constructor here..
//some methods here..
And some sample program like the one below which implements the above..
//filename: test.java
//located: c:\school\csc365
import csc365.*;
import java.io.*;
class test.java
//creates some sentence object
//uses the object's methods
//some other things.
As I understand it, the test.java file should not compile because the csc365 package is not in the correct directory. (assuming of course, the classpath is like c:\school\csc365;c:\school )
But, ... where then should the sentence.java be located? In a subdirectory of c:\school called csc365 (i.e c:\school\csc365\) ?
And thus that would mean the test.java file could be located anywhere on the hard drive?
I suppose, I just need a little clarification on the correlation between a package's "name" (i.e package csc365; ) and its corresponding directory's name, and also how the javac compiler searches the classpath for java classes.
..So, theoretically if I were to set the classpath to look in every conceivable directory(provided the directory names were all unique) of the harddrive, then I could compile a test.java anywhere?
As a note: I have been able to get the test.java file to compile, by leaving out the import statement in the test.java file, and also leaving out the package statement for the sentence class, but I assume this is because the files are defaulted to the same package?

Hi Mary,
No, import isn't analogous to C++ namespace - Java package is closer to the namespace mark.
import is just a convenience for the programmer. You can go your whole Java career without ever writing an import statement if you wish. All that means is that you'll have to type out the fully-resolved class name every time you want to use a class that's in a package other than java.lang. Example:
// NOTE: No import statements
public class Family
   // NOTE: fully-resolved class names
   private java.util.List children = new java.util.ArrayList();
}If you use the import statement, you can save yourself from typing:
import java.util.ArrayList;
import java.util.List;
public class Family
   // NOTE: fully-resolved class names
   private List children = new ArrayList();
}import isn't the same as class loader. It does not bring in any source code at all.
import comes into play when you're compiling or running your code. Java will check to make sure that any "shorthand" class names you give it live in one of the packages you've imported. If it can't find a matching fully-resolved class name, it'll give you a message like "Symbol not found" or something like that.
I arrange Java source in a directory structure that matches the package structure in the .class files.
If I've got a Java source file like this:
package foo.bar;
public class Baz
   public static void main(String [] args)
        Baz baz = new Baz();
        System.out.println(baz);
   public String toString()
       return "I am a Baz";
}I'll store it in a directory structure like this:
root
+---classes
+---src
      +---foo
           +---bar
                +---Baz.javaWhen I compile, I go to root and compile by typing this:
javac -d classes foo/bar/*.javaI can run the code from root by typing:
java -classpath classes foo.bar.BazI hope this wasn't patronizing or beneath you. I don't mean to be insulting. - MOD

Organize iTunes file list by Directory Structure instead of artist/album?

Hello, I have searched for different audio players for os x which might have this feature but so far have had no luck. What I'm looking for is a feature similar to that of foobar2000 for win32 where I can organize my music by directory structure without the iTunes automatic organization by artist/album. Is there a way I can accomplish this in iTunes with some sort of xml config or hidden options? Thanks.

You don't have to have iTunes move music around on your hard drive (Preferences>Advanced>General, uncheck Keep iTunes Music folder organized and Copy files to iTunes Music folder when adding to library) but I suspect that's not what you're asking. You can't automatically view music from within iTunes by directory structure. iTunes organizes by ID3 tags ("mp3 tags"). You could, I suppose, spend a lot of time replicating your directory structure by using folders and playlists within iTunes but you'd probably have to do it all by hand.
You could check out Doug's Scripts to see if there are some scripts that might help.

How to create a tree based on directory structure

I want to create a hierarchical tree in Forms 6i based upon a file system directory structure (similar to Windows Explorer). How can I populate a tree with this information, is there something that I can call or write that would return the file system structure in a format that I can populate my tree?
Any advice would be greatly appreciated.
Thanks
Richard

Your link does not seem to work.They're re-jigging all the links to accomodate the hot poop on Oracle's latest and greatest, 10G. So at least the website is on schedule even if the actual software delivery dates have slipped :P

Directory Structure for multiple applications at one host

Can I have multiple (more than one) WEB-INF directory structures in the public_html directory for different web applications? If I do this, how do setup the url-pattern in the Servlet Mapping tag in the web.xml file? How do I setup the URL that calls the servlet from the HTML that has been send to the user�s browser?

If I understand your question, you want multiple contexts. All App Servers/Web Servers allow you to setup multiple contexts. Normally if your root context is in /home/myhome/app_server/
then you would setup multiple contexts by creating a folder for each context:
/home/myhome/app_server/context1/
/home/myhome/app_server/context2/
Each would have their own full application/website. And the way to reference these would be as such:
if the domain, www.mydomain.com, is mapped to /home/myhome/app_server/
www.mydomain.com/context1/
www.mydomain.com/context2/
I think that is what you were asking. Hope it helps

Is there any way to specify a URL in the servlet-mapping that doesn't need to be in the directory structure?

          I migrated from WebLogic 5.1 to 7.0.2 Something I used to have set-up in 5.1 no
          longer
          works.
          I am using the weblogic.servlet.FileServlet and have the URL "/cxedocs/" mapped
          to this
          servlet. So whenever the URL http://localhost:7001/cxedocs/en_US/index.html
          is used it would use the docHome associated with the /cxedocs/ URL and then append
          the "en_US/index.html" on to it. So let's say d:\temp\en_US\index.html
          But now for WL 7.0.2 it appears that the URL also needs to be in the directory
          structure.
          So it now takes the docHome "d:\temp" adds the URL "/cxedocs/" and then appends
          the
          rest - so d:\temp\cxedocs\en_US\index.html.
          I can't require that the "cxedocs" directory be there. Is there anyway to map
          a certain URL
          without requiring it in the directory structure. I looked at virtual directory
          mapping too but
          it still seemed to require this.
          Any help would be appreciated!
          Thanks!
          -Lori


          I opened up a case with support on this. After some research they came back with
          that
          NO there is no way to do this. In 6.0 it was changed to follow the spec which
          restricts this.
          The URL must be part of the directory path.

I have copied many photo's from another laptop to my Mac. The older photo's are in directories with names that help me select what I need to view. I would like to have all my imported new photo's also bee added to the directory structure I have in Finder

I have copied many photo's from another laptop to my Mac. The older photo's are in directories with names that help me select what I need to view. I would like to have all my imported new photo's also bee added to the directory structure I have in Finder but my new photo's are all in iPhoto. I want to use directories for storing and iPhoto for viewing. Is this possible or do I need to have all my photo's in iPhoto??
Mitch

iPhoto is not a Photo Viewer. It's a Photo Manager and designed for looking after the files while you organise the Photos. It really works much better if you let it manage those files. If you use iPhoto you never go near those files because iPhoto is your start point for anything you want to do with your Photos - the point of the pplication.
You can run iPhoto in Referenced mode, where it does not copy the files to the Library, but I caution you that you are making life a lot more difficult for yourself by doing that.

Export images to a directory structure based on a collection tree?

A question:
Will lightroom have the capability to export images to a directory structure which mirrors a collections logical structure?
The reason I ask this is that when I create websites using third party tools (eg, Jalbum) I typically generate a flash or HTML based site with an menu structure for navigating the images.
So, the image interface is not simply a "flat-file" display as per the templates in Lightroom beta.
To do this, with previous image management tools (eg, iMatch) I create a hierarchy of images based on the categories (or collections) that the images are assigned to, export the images in a folder tree reflecting their categories (or collection), then use, say, Jalbum, to generate the website with the menu tree reflecting the folders/images.
This is extremely useful for more complicated image websites with categories and a large no of images.
If this function was built into Lightroom I guess it would be in the export function such that the "write to folder" box could take an argument {collection name} which would create a folder tree reflecting the collections logical tree which is being exported.
Apologies if this topic has been raised previously. But this function is extremely useful if you are using third party html tools or simply building websites by hand.
Regards
Alistair

I started simmilar thread in Lightroom Feature Requests few months ago, but can't find it anymore since new forum version...
What I can suggest as a new feature is export to directory structure from collections or second option from keywords. Probably more usable and easier to implement would be from collections.
What I need it to export many photos to different directories pretty often, and this would be great help since I could arrange them in collections and collection sets. Then select collection set and export it in a manner that collection set would be main export directory, and each collection within the set would be exported to its own folder within main collection set export folder.
This would be much appreciated feature in near future
Thank you for great product by the way

Creating a Standby Database with the Same Directory Structure

Hello gurus,
I am self-learning the feature Oracle Data Guard, so I am testing it on Oracle 10g R2.
At Oracle documentation there is a section F.4.: Creating a Standby Database with the Same Directory Structure*, that explains how to create a standby database with RMAN but there is something that I don´t understand:
In the standby server, I created a database with the SID equal to production database* with the objetive to have the same directory structure, but when I try to startup nomount the standby database with pfile appear this expected error:
ORA-16187: LOG_ARCHIVE_CONFIG contains duplicate, conflicting or invalid attributes
So my question is: Is possible have the Same Directory Structure on both: Production and StandBy server?
Thanks in advanced.

Uwe and mseberg: thanks for your quick answers
I have a doubt: How can you have the same directory structure if you have differents SIDs?, for example if you follow the OFA suggestions you would must have:
On Production server: */u01/app/oracle/oradata/PRIMARY/system.dbf*
On StandBy server: */u01/app/oracle/oradata/STANDBY/system.dbf*
Or you created the directory structure manually on StandBy server? For example replacing the string STANDBY* to PRIMARY* before create the database using dbca.
Do you understand my doubt? Excuse me for my english.
Thanks.

Directory structure for ABAP+JAVA Dialog Instance

Hello,
Can any one clarify how will be the directory structure in a case where we have ABAP+Java System?
For Central Instance,DVEBMGS<instance no>
Central Services,SCS<instance no+1>
Ex:DVEBMGS20
SCS21
If I have another dialog instance,can I have only ABAP or only Java in that?What will be the directory structure?But I read that they will be in 1:1 ratio
Will it be D22(Only ABAP) or J22(Java only).
As a dialog instance,can ABAP exist with out JAVA.
or can JAVA exist without ABAP
Please explain the directory structure with an example.
Thanks,
Sudheer.

Directory structure for a J2SE+J2EE project: suggestions are very welcome

Hi, I have to start coding and organizing the CVS tree of an already mature project which is J2SE. This J2SE project can be described as a "core engine" for something else, and is a quite large project, and up to now has only a command line User Interface. I organized the dir structure as this:
/build.xml
/src/
/src/java/<package>/...../*.java
/src/demo/<package/...../*.java
/src/test/<package>/....../*.java
when I ant compile, all the .classes will be done in the "build" directory (reflecting the structure in the "src" dir):
/build/
/build/java/<package>/....../*.class
/build/demo/<package/...../*.class
/build/test/<package>/..../*.class
I am happy with this, but now comes the issue: a web interface to use this core engine (it will have the same package namespace) is in developing progess, so I have to put somewhere the *.jsp, the WEB-INF dir with web.xml and servlet sources: how would you do this? And where would you let Ant put the compiled servlet classes?
I can modify the previous directory structure to accomodate the J2EE part, this is really not a problem!
Thanks to who can suggest me a clean solution
Alessio

Create a web-inf folder at the same level of src and
jsp folder inside src
i mean
/build.xml
/src/
/src/java/<package>/...../*.java
/src/demo/<package/...../*.java
/src/test/<package>/....../*.java
/src/jsp
/web-infSo, would you put in /src/jsp only the *.jsp?
And what in /WEB-INF ? What woud you put there? Would you do something like:
/WEB-INF/web.xml
/WEB-INF/src/<package>/..../<my_servlets_and_j2ee_stuff>.java
/WEB-INF/classes/<package>/..../<my_servlets_and_j2ee_stuff>.java
In this manner sources and classes are in the same tree, it does not seem very clean to me, expecially if you consider that probably I must have a "test" directory to unit test some j2ee stuff (as for the j2se stuff in "src"): how would you do that?
Is this directory structure anyway what you meant or not?

Directory Structure

I just created a network installer for Q4 Release. We have Developers, Full, and Debug licenses. The DVDs were copied to the VLM computer's harddrive. When I created the Debug configuration, the Network Installer reported the the DVDs did not have to be modified and would copy them directly. When the network installed was done, it did not create the directory structure similiar to what the help file below shows.
LabVIEW 8.0
\_SourceFiles
\Fourth Floor Engineering
\Client
vlmclient.exe
other files
setup.exe
\Applications Group
\Client
vlmclient.exe
other files
setup.exe
Figure 1. Network Installer Directory Structure
I would have expected
LabView 8.6
    \Source Files
    \Debug
        \Client
           vlmclient.exe
         setup.exe
Only the \DISK1, \DISK2, \DISK3, \DISK4 were created. The vlmclient.exe was not created.
Paul
Solved!
Go to Solution.

When you were creating the VLI, did you get a popup message that said the source did not need modification? If you saw that popup, that means VLM was not pointed to a valid source file location, which will cause a direct copy of the files with no additions.
If you select a valid source location, you should not see that message and the Product Name field should automatically populate. If you are using the Dev Suite or Platform DVDs, you will need to follow the steps in the KnowledgeBase article I refered to in my previous post.
Here is an example of what copying the installer directory could look like if you just copy the LabVIEW 8.6 Platform DVD 1:
LabVIEW 8.6 Platform DVD 1\_SourceFiles
                                                        \(the _SourceFiles directory will contain a copy of DVD 1)
                                                \LV PDS (License Set name)
                                                        \setup.exe
                                                        \Client
                                                                 \vlmclient.exe (as well as some other vlm files)
On the client machine, you would want to run "setup.exe" to begin the installation.

Directory Structure Errors

In TechTools ( came with Applecare ) i got a failed on Directory Structure, second time since owning my couple month old machine, first time apple recomended reloading.
i dont mishandle it, dont bump, dent, etc, the laptop.
but all of a sudden sometimes my USB keyboard/mouse wont register as being plugged in all the time / techtools HDD errors.
only recent think if done is instal Onyx to look over the logs, and little while after ( days ) the issues started hapening,, same with last time, but didnt think it was Onyx, now im starting to wonder, anybody else have any issues like this, and Would Onyx couse it ( doubt it, but since onyx goes deep into the system, no idea )

It is an interesting coincidence that I came across this thread today because I had the exact same issue myself last night.
I have plenty of space available on my HDD 73.1GB.
I downloaded the latest Onyx last night and when it starts it checks the disk. I got an error on the startup volume so I ran Tech Tools as well.
TechTools came up with that same failed Directory Structure error.
I next tried to reboot the comptuer holding down Apple/S and entering fsck -fy
That resulted in errors. Tried re-running it 3-4 tims to see if it would resolve anything but got the same error with every attempt.
I then booted from DiskWarrior and ran that. It seemed to correct a number of issues and now TechTools, Onyx, Disk Utility etc. find no problems. But it was kind of an odd occurance and interesting to find I was not alone in getting that last night.
The odd thing though is that I also checked my Mac Pro while I was wating on this one to finish and had directory errors on that one as well so had to run DiskWarrior on both.
I was kind of concerned about that to say the least.

Directory structure after upgrade to iPhoto 6

After upgrading to iPhoto 6, it appears that my photos were copied from the old, date-based structure into a new directory structure, but the old structure was left behind.
What is the layout of the new structure, and can the remaining old structure be discarded at this point?
Thanks for any insight you might be able to offer...

The new structure organizes photos into Originals and Modified folders. There is a third folder called Data that contains thumbnails created for the photos (smaller pictures used for better performance). These three are essential for iPhoto 6 to work.
Each folder contains a folder for each year (a year folder is created if you have even one photo from that year, e.g. a photo from 4/3/2004 will create a folder called "2004" and any other photos from that year will then be placed within it.
Every import creates a serially numbered Roll folder within the year folder. So if you import photos including IMG_234.jpg from 4/3/2004, for example, the location of IMG_234.jpg will be:
iPhoto Library/Originals/2004/Roll 1/IMG_234.jpg
And Roll 1 will have other photos imported in the same session. If you modify the photo within iPhoto (enhance, retouch, etc), the modified copy will exist in:
iPhoto Library/Modified/2004/Roll 1/IMG_234.jpg
The Data folder will contain a thumbnail for the image in the same path as the Originals:
iPhoto Library/Data/2004/Roll 1/IMG_234.jpg
So inside the iPhoto Library folder, you will see some files and those three folders with their sub-structure folders. Other things within the top level of the iPhoto Library folder, are leftovers from the previous structure - such as a folder called "2004" or "2005" that ISN'T inside Originals, Data, or Modified folders.
PhillyPhan's advice is sage. Don't mess with the insides of the iPhoto Library. However, I did verify on my own system after I upgraded, that year folders at the top level of the iPhoto Library are from previous versions of iPhoto. So you could move those, and those only, to a separate folder on your HD. I moved those off to a DVD-ROM and haven't seen problems since.
Remember: Don't touch any files, and don't touch anything within Data, Originals, and Modified folders.

Directory Structure ?s for an Exploded Web Application

We have an application that consists only of JSPs and Servlets, no
EJBs. I am researching whether or not it's worthwhile to start using
EJBs. We're also migrating from Weblogic 5 to 6.1. I've managed to
migrate our application fine and have it up and running on WLS 6.1.
I'm confused about the exploded directory structure, the
application.xml file, where to put the EJBs and whether or not I have
to jar them. Here's our current directory structure:
DefaultWebApp/               JSPs here
DefaultWebApp/WEB-INF          web.xml and weblogic.xml here
DefaultWebApp/WEB-INF/classes     Servlets and other classes here
DefaultWebApp/WEB-INF/lib     do my un-jar-ed EJBs go here?
I've been reading a lot of BEA's documentation, particularly
‘Deploying an Exploded J2EE Application' and a ‘Web Application PDF',
and looking for relevant threads on the weblogic.developer.interest
groups. It looks like the application.xml should go in a new
DefaultWebApp/META-INF directory. But where do the EJBs go?
I also see some directory structures with another /web directory
that's confusing me.
Oh, I've also managed to compile and jar up a trial Stateless Session
EJB. Then I think I ‘auto-deployed' it into the /applications
directory, and Weblogic seems to recognize it. But when I tried to
reference it in a JSP, I got an error message ‘class x is public,
should be declared in a file named x.java'. I'm assuming this is
related to the application.xml, where I need to define the ejb
directory.
Thanks.

To deploy your web app together with your EJBs, you need to create
an "EAR" structure. Both your webapp and your EJB jars will be within
this new structure, at the same level. You may jar up your EJBs, or you
may explode their structure, it's up to you.
The resulting structure should look something like below:
EnterpriseApp/ <-- new top level
EnterpriseApp/META-INF/
EnterpriseApp/META-INF/application.xml
EnterpriseApp/lib/ <-- shared libraries (if any)
EnterpriseApp/EJB/ <-- ejbs go here
EnterpriseApp/EJB/META-INF/ejb-jar.xml
EnterpriseApp/EJB/META-INF/weblogic-ejb-jar.xml
EnterpriseApp/EJB/com/your/ejb/classes/here
EnterpriseApp/WebApp/ <-- move your current app here
EnterpriseApp/WebApp/index.jsp <-- JSPs goes here
EnterpriseApp/WebApp/other.jsp
EnterpriseApp/WebApp/WEB-INF/web.xml
EnterpriseApp/WebApp/WEB-INF/weblogic.xml
EnterpriseApp/WebApp/WEB-INF/lib <-- ui libraries go here
EnterpriseApp/WebApp/WEB-INF/classes <-- servlets go here
The above structure is identical to the structure to an EAR file, only "exploded"
as actual files and directories instead of being "jarred" into a single EAR file.
Your application.xml in this case would specify something like:
<application>
<display-name>EnterpriseApp</display-name>
<description>My Enterprise Application</display-name>
<module>
<ejb>EJB</ejb>
</module>
<module>
<web>
<web-uri>WebApp</web-uri>
