Shared libraries - what for?

can anyone offer a reasonable explanation for the following.
iphoto has the ability to share libraries - great!
i can share the library on my MacMini - good.
i can see it fine on my MBP and copy/paste pictures into my MBP library - cool
but, i cannot copy/paste pictures from the MBP back into the MacMIni - ???, why not?
I accept this would be an issue with iTunes and DRM etc. etc., but what is the usefulness of sharing picture libraries that cannot be expanded/updated?
am i missing something? is it possible? can i do this if i spend money on Aperture?
do you think apple understand this issue?
what do all the macbook air customers do when their hard drives are full with iphoto and itunes libraries - take their external drives with them?
ah yes - make a computer that weighs 3.0lbs and forget about 30lbs of extras to make it function.
starting to sound like a rant now...

i cannot copy/paste pictures from the MBP back into the MacMIni - ???, why not?
Have you tried, while on the Mini, copy photos from the MPG library to the Mini library?
what do all the macbook air customers do when their hard drives are full with iphoto and itunes libraries
The Air is not designed to be a full service laptop. It's designed for the basic functions that business men need and then connect with a computer at home for much of the other stuff. I'm sure many will have two libraries, a full one at home a small one, with only the latest or most needed photos, to take on the road with the Air. Then use iPhoto Library Manager to copy new photos from the Air to the primary and needed photos from the primary to the Air.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
Note: There now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

JBI Shared Libraries

Hi. I have arrived to a new project and they are working with JBI (developing BPEL) with Glassfish + openESB.
I have no experience with JBI and I've been request to do some research about JBI Shared libraries. The problem comes for us when two composite aplications have to share one resource (in this case an .xsd file that includes other schema files). I don't know how to do such a thing. What I've done so far is:
- create a new project (as a java project in netbeans) with the needed files
- create the jbi.xml file under the META-INF folder
<?xml version="1.0" encoding="UTF-8"?>
<jbi
    xmlns="http://java.sun.com/xml/ns/jbi" version="1.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:identification="http://www.sun.com/jbi/descriptor/identification/v1.0">
    
    <shared-library class-loader-delegation="self-first">
        <identification>
            <name>my-shared-lib</name>
            <description>JBI shared library</description>
            <identification:VersionInfo component-version="1.0.0" build-number="000001"/>
        </identification>

            <path-element>./xsd/Requests/types.xsd</path-element>
        </shared-library-class-path>
    </shared-library>
</jbi>- deploy in the glassfish server via web interface
But when the POJO class that needs that file it is not available (neither in the classpath). What I have to do or what I'm doing wrong?.
Thanks in advance

"Also with regards shared libraries - whn some people come out of their browsers they clear their temporary internet folders of everything ie: cached/cookies too. So those people would have to redownload everytime. Is that right?"
Cookies do not matter for caching. If they set their browser to clear cache - ALL files will be loaded every time new sessions starts.
"So even if I create that framework to test for changes which I doubt I can do then
it sounds like an excellent idea to have various shared libraries just for the fact that it doesn't matter
about file size but the positive is that if I change one library the other remain unchanged.
Would that be a correct assumption?"
There is no single correct answer or even recommendation to how to deal with RSLs (Runtime Shared Libraries). Each application dictates its own rules that depend on objects availability at the points they need to be consumed. Size may or may not matter (again, answer depends on architecture and internal application business logic).
From the standpoint of choices of what to load and what is changed, if there is no mechanism that detects changes and because of how caching is done - it is only all or nothing approach (either all RSLs have to be loaded per session or one relies exclusively on browser cache).
Change detection is pretty difficult to implement if you rely on client side only because, again, how cahing is handled.
Also, conceptually RSLs must be very stable entities and shouldn't be something that changes often if ever. If they are meant to change often - it is definitely a critical design flaw. Perhaps, this case indicates that what is actually happens is that RSLs attempt to represent data/information/presentation layers. Data MUST EXIST TOTALLY separate from logic and presentation. I cannot stress it strong enough - mixing information, presentation and logic leads to major inefficiencies if not disasters.

Best Practice for External Libraries Shared Libraries and Web Dynrpo

Two blogs have been written on sharing libraries with Web Dynpro DC, but I would
like to know the best practice for doing this.
External libraries seem to work great at compile time, but when deploying there is often an error related to the external library not being a deployed component.
Is there a workaround for this besides creating a shared J2EE library which I have been able to get working? I am not interested in something that works, but really
what are the best practice for this. What is the best way to limit the number of jars that need to be kept in a shared library/ext library. When is sharing ref service/etc a valid approach vs. hunting down the jars in the portal libraries etc and storing in an external library.

Security is mainly about mitigation rather than 100% secure, "We have unknown unknowns". The component needs to talk to SQL Server. You could continue to use http to talk to SQL Server, perhaps even get SOAP Transactions working but personally
I'd have more worries about using such a 'less trodden' path since that is exactly the areas where more security problems are discovered. I don't know about your specific design issues so there might be even more ways to mitigate the risk but in general you're
using a DMZ as a decent way to mitigate risk. I would recommend asking your security team what they'd deem acceptable.

Why plugin/addon concept for Runtime Shared Libraries not implemented in Flex?

Hi All,
I am posting my refined query here in continuation to my post Fundamental and crucial drawback with Flex in Flex India Community as my last refined query was left unanswered though I feel there is a definite sense of purpose to it.
Why plugin/addon concept for Runtime Shared Libraries not implemented in Flex?
Here is why I feel it should be implemented in Flex.
Though Runtime Shared Libraries SWF file can be cached in the client browser and just need to be loaded only once when the user access a Flex application for the first time,
"40-60% of daily visitors to your site come in with an empty cache. Making your page fast for these first time visitors is key to a better user experience."
Qouting from 'Best Practices for Speeding Up Your Web Site' as described in Tenni Theurer's blog post Browser Cache Usage - Exposed!
While still retaining the cacheability of RSL's for compatibility reasons, flex should give the flexibility and thereby enhance performance by offering RSL's as a plugin/addon.
Looking for your comments and insigts on the same.
Thanks,
Ram Manoj Kongara.

I finally skimmed through the links you posted. The terms plugin and addon
are not in either of the articles so I'm unclear what you are suggesting.
The topic seems to be about application performance. The Flash Player
supports a cross-domain cache of actionscript libraries separate from the
browser cache. Each official release of Flex contains a set of these
libraries. As new Flash Player versions or new Flex versions are released,
and users visit sites utilizing those new versions, the browser picks up the
latest Flash Player and the Flash Player picks up the latest Flex libraries.
These days, it only takes a few months for a new Flash Player to achieve
major saturation in browsers although it still takes a bit longer for Flex
libraries to achieve saturation.
Adobe will soon be hosting these libraries so if you build your application
to leverage these libraries, you will find that the total download from your
server will be minimized, limited to only your application code and assets,
although you might want to serve the libraries in case they are not already
in the cache if you see high latency to the Adobe servers on a cache miss.
The SWF or SWFs you do serve off your servers should be optimized through
normal good application development practices. Flex provides features such
as deferred instantiation in its ViewStack and Accordion containers to defer
the creation of objects until viewed. Flex has a ModuleManager to allow you
to not download parts of your application until they are needed. A
model-view or MVC architecture will make it easier to create modular
boundaries within your application and leverage these features.
If I have not addressed your concerns please describe your issue in more
detail.

Can't find "Look for shared libraries" in the Sharing pane of iTunes preferences. How can I find it?

I am trying to set up Home Sharing between my computer and my wife's. Sharing keeps disappearing from the side bar although Home Sharing is turned on for both computers. Using the Help tab it says to check the "Look for shared libraries" in the preferences/shared box. The problem is that "Look for shared libraries is not there to select. Any ideas how I can sort this out?

I'm having a similar issue even after the "Shared Libraries" box is checked in General preferences on iTunes...
On early verisons of iTunes i had no problem with sharing or remote access via iPad. I really need to figure out how to get this working.

HPUX shared libraries versions of XML parser v2 for C++

Hi All,
Could somebody tell me whether Oracle have any plans to distribute shared versions of the xml libraries that ship with the C++ XML Parser for HPUX.
I am working on a project that uses shared libraries that in turn use the Oracle XML parser. I have managed to get the final executable to link to the xml static library (the symbols are unresolved when I link the sl, but sort themselves out on the final link) but HP do not recommend mixing static & shared libraries - and my code size increases by quite a bit using this method.
I would much prefer to use shared libaries as I do when I link the Oracle 8.1.6 libraries.
Thanks in advance,
Steve Dalton

I was able to find out that the XDK libraries on HPUX for Oracle 8.1.7 are built with the +z compiler option (unlike the current versions on OTN for HPUX). So, that will give you position independent code and should allow you to build a shared library.

Can client dynamically link to shared libraries for different versions ?

Can Oracle client dynamically link to Oracle shared libraries if the versions are different ?
Hi:
I apologize for this newbie question:
We are using PRO C to generate the client C code.
We can compile both dynamic and static versions of our Oracle client.
Our question is:
is it possible to compile a dynamically linked Oracle client in say version 10.1.0.2 and actually run the application against say version 8.1.7.0 environment ?
That is, can an Oracle client dynamically link to the Oracle shared libraries if the versions are different ?
If it is possible, then how to modify the makefile
to enable Oracle client to reference different versions
of shared libraries ?
Thanks
JL

What you describe is not supported.

How can i share my library with my new computer when the itunes on the new computer does not have the "look for shared libraries" command in the preferences/shared pane?

It worked fine before i updated the most recent update, My old computer readds the new one but the new one does not read the old one now.

Is the iTunes library actually shared on the old computer?
I have never had a need for forcing iTunes to look for shared libraries, it simply detects them.

How to use g++ to build shared libraries for labview in linux?

does anyone knows if it's possible to compile a shared library in linux with g++ that could be recognized by labview?
thks
JP

Hi JP,
Yes you can use g++ to build shared libraries that labview can use. You'll want to give your C++ library a C interface. This is really common practice. You can do this by simply declaring functions as 'extern "C"'. Here is a link with more information:
http://www.parashift.com/c++-faq-lite/mixing-c-and-cpp.html#faq-30.8
I've personally worked on projects that do exactly what you want to do.

What is factory default "Sharing & Permissions" setting for User folders?

System:
Mac OS X Lion 10.7.2
MacBook Air (Mid 2011)
Single User – Administrative Account
Question:
What is factory default “Sharing & Permissions” setting for User folders (Desktop, Downloads, Library, Movies, Music, Pictures, Public), subfolders, and documents and other contents?
I’m thinking the factory default “Sharing & Permissions” for all of the above (except Drop Box in the Public folder) is as follows, but not certain.
Name                          Privilege
myusername (Me)    Read & Write
staff                            Read only
everyone                   Read only

Are these also the settings on your Documents folder and the various files in the Documents folder? Same question for your Library folder?
Name                          Privilege
myusername (Me)    Read & Write
everyone                   No Access

Use of deployment classpath or shared-libraries to pick-up "custom" classes

Hi,
I’m trying to determine an approach to dealing with how classes are found in a deployed ADF application via classpath, etc. I’ve tried to explain the situation below as best I can so it’s clear. If you have any comments/suggestions as to how this could be done, it would be much appreciated
Current Application structure:
Consists of an application initially deployed to OC4J 10.1.3.4 using an alesco-wss.ear file
Application contains a single Web Module, initially deployed as wss.war file within the alesco-wss.ear file above.
The Web Module (wss) was built in JDeveloper 10.1.3.4 using 2 projects, a Model and ViewController project, and uses ADFBC.
The Model project seems to also generate an alesco-model.jar file in the /WEB-INF/lib/ folder, even though Model classes are in the /WEB-INF/classes/ folder below?
Exploded structure of application on application server looks something like:
applications/alesco-wss/META-INF/
/application.xml <- specifies settings for the Application such as Web Module settings
/wss/
/app/ <- directory containing application .jspx pages protected by security
/images/ <- directory containing application images
/infrastructure/ <- directory containing .jspx files for login, logout and error reduced security
/skins/ <- directory containing Skin image, CSS and other files
/WEB-INF/
/classes/ <- directory containing application runtime class files as per package sub-directories
/lib/ <- JAR files used by application (could move some to shared-libaries?) – seems to contain alesco-model.jar
/regions/ <- directory containing .jspx pages used for Regions within JSPX template page
/templates/ <- directory containing template .jspx pages used for development (not really required for deployment)
/adf-faces-config.xml
/adf-faces-skins.xml
/faces-config.xml
/faces-config-backing.xml
/faces-config-nav.xml
/region-metadata.xml
/web.xml
testpage.jspx <- Publicly accessible page just to test
The application runs successfully using the above deployment structure.
We plan to use the exploded deployment structure so that updates to pages, etc. can be applied individually rather than requiring construction and re-deployment of complete .EAR or .JAR files.
What I’m trying to determine/establish is whether there is a mechanism to cater for a customisation of a class, where such a class would be used instead of the original class, perhaps using a classpath mechanism or shared library?
For example, say there is a class “talent2.alesco.model.libraries.ModelUtil.class”, this would in the above structure be found under:
applications/alesco-wss/META-INF/classes/talent2/alesco/model/libraries/ModelUtil.class
Classes using the above class would import “talent2.alesco.model.libraries.ModelUtil”, so they effectively use that full-reference to the class (talent2.alesco.model.libraries as a path, either expanded or within a JAR).
From the Oracle Containers for J2EE Developer’s Guide 10.1.3 page 3-17, it lists the following:
Table 3–1 Configuration Options Affecting Class Visibility
Classloader Configuration Option
Configured shared library <code-source> in server.xml
<import-shared-library> in server.xml
app-name.root <import-shared-library> in orion-application.xml
<library> jars/directories in orion-application.xml
<ejb> JARs in orion-application.xml
RAR file: all JARs at the root.
RAR file: <native-library> directory paths.
Manifest Class-Path of above JARs
app-name.web.web-mod-name WAR file: Manifest Class-Path
WAR file: WEB-INF/classes
WAR file: WEB-INF/lib/ all JARs
<classpath> jars/directories in orion-web.xml
Manifest Class-Path of above jars.
search-local-classes-first attribute in orion-web.xml
Shared libraries are inherited from the app root.
We have reasons why we prefer not to use .JAR files for these “non-standard” or “replaced” classes, so prefer an option that doesn’t involve creating a .JAR file.
Our ideal solution would be to have such classes placed in an alternate directory that is referred to in a classpath such that IF a class exists in that location, it will be used instead of the one in the WEB-INF/classes/ directories, and if not such class is found it would then locate it in the WEB-INF/classes/ directories.
- Can a classpath be set to look for such classes in a directory?
- Do the classes have to replicate the original package directory structure within that directory (<dir>/talent2/alesco/model/libraries)?
- If the class were put in such a directory, without replicating the original package directory structure, I assume the referencing “import” statements would not locate it correctly.
- Is the classpath mechanism “clever” enough to search the package directory structure to locate the class (i.e. just points to <dir>)?
- Or would the classpath mechanism require each individual path replicating the package structure to be added (i.e. <dir>/talent2/alesco/model/libraries/ and any other such package path)?
If we are “forced” to resort to the use of JAR files, does a JAR file used for the purpose of overwrite/extending a sub-set of classes in the original location need to contain ALL related package classes? Or does it effectively “superset” classes it finds in all JAR files, etc. in the whole classpath? That is, it finds talent2.alesco.model.libraries.ModelUtil in the custom.jar file and happily goes on to get the remainder of talent2.alesco.model.libraries classes in the other core JAR/location. Or does it need all of them to be in the first JAR file for that package?
Any help would be appreciated to understand how these various class visibility mechanisms could be used to achieve what is required would be appreciated.
Gene

So, nobody's had any experience with deploying an ADF application, and providing a means for a client to place custom classes in such a way as they're used in preference to the standard application class, effectively to implement a customised class without overwriting the original "standard" class?

Shared libraries?

Is there an option or a solution within Photos to do shared libraries, multiple libraries on one computer and between multiple computers? I am reading and initially it looks like there is less flexibility for this then there was in iPhoto/Aperature. And the AD line of "For the first time, iCloud Photo Library gives you access to your entire Mac photo and video library from all your devices" doesn't work, when one iPhoto/Aperature library is 250GB, several others are 25-50GB each, looking at an aggregate over 500GB of media. Not expecting this to be a DAM, but initially it looks like options are less. Very hesitant about converting libraries at this point, and I have been running Photos Beta for several months now.
Advice?

Thanks.
I figured as much, I was hoping that they would have built some functionality into this for home/small business shared libraries. With so many homes let alone small businesses that have shared networks that rely on sharing resources, it would seem obvious to build that function, but I guess there are other objectives.
We have been running iPhoto then Aperature for so long and it is integrated into all computers and devices. Saying that we are not looking for a DAM is because we have managed to make a framework of networked libraries that does what we need, plus it is more hassle to switch to a DAM (plus I can't find one at a price we are willing to pay).
Just going to have to bite the bullet and switch to a DAM sometime soon.

Sharing Libraries across accounts on one computer

I'd like to know an easy method to share iPhoto libraries across accounts on one computer. It looks like iPhoto is more or less ignoring this topic. I have searched the web for tips, found some, yet the instructions are complicated and what seemed to be the best one didn't work. Anyone in this forum that can help me?

haha, brian has a hidden message in there.
Anyway, here all the links I have for sharing. The last link for using ACLs is the one I think you are thinking of.
SHARING IPHOTO LIBRARIES
Sharing libraries between users on the same local network
You can also share a library on the same machine between users the same way.
Sharing libraries between users on the same machine...
-both users must have sharing enabled in their iPhoto Preferences
-both users must be logged in and have iPhoto running
-Remember that you can only view the other library. You can't edit the photos or play the saved slideshows or view the made books or burn them to CD or DVD. The books and slideshows will show up as an album. You can play that album as an "on the fly" slideshow. You can drag images from the sharing library to your library in the source column to import them to your library. You can then edit, add to albums, books, slideshow, etc.

Without knowing what you have installed or what modifications you have done it is not possible to say what goes wrong. Like I previously mentioned, you may have installed an incompatible version of a core system library. Sorry, I'm not going to read any installation manual to find out what you might have done wrong. You may need to reinstall the complete system or just the popt installation package.
Based on my experience people sometimes seem to misunderstanding the concept of software version requirements, which are always minimum version requirements and does not mean, for instance, software made for gcc 4.1.10 does not work under 4.1.12. You cannot simply upgrade or downgrade core system libraries without affecting the installed system. Using YUM to install software will check this and prevent you from breaking your system. RPM does not check any dependencies and hence can break your system beyond repair.

Sqlplus: Error while loading shared libraries: libsqlplus.so:

Hi
The Error is as follows:
sqlplus: Error while loading shared libraries: libsqlplus.so: cannot open shared object file: no such file or directory
Installed R12 with RUP2.
User Oracle already exists.
I tried to create a user appsdev as follows:
#adduser appsdev
#passwd appsdev
#cd /home
#chmod 500 appsdev
login as user appsdev/appsdev
run the env file from $ORACLE_HOME
$sqlplus
sqlplus: Error while loading shared libraries: libsqlplus.so: cannot open shared object file: no such file or directory
if run the env file and sqlplus from user ORACLE.i don't get the error.
but from the appsdev user i get the error.
what should i do to execute sqlplus successfully from appsdev user.
regards,
charan

if run the env file and sqlplus from user ORACLE.i don't get the error.
but from the appsdev user i get the error.Is the "appsdev" user the owner of the application tier? If so, source the env file under %APPL_TOP% and check then.
Did you specify the dba group as the primary group for "appsdev" user?
