Trying to Understand IP Addresses

I've been studying routing, and although I feel like I have a basic idea of routing and the different protocols associated with it, I've always had this IP address question.
If I you are given the whole network 70.70.0.0/16 by your ISP (I'm using classful addresses to keep it real simple), than why can't that same ISP give someone else the network 70.70.0.0/24.
Since the first network has a 70.70.0.0/16 address, and the other network would have a 70.70.0.0/24 network, wouldn't that mean that it's a whole separate network since the netmasks are different. I know you can't assign those two networks out to two separate companies, but can someone explain why? Thanks!

The network 70.70.0.0/16 includes the range 70.70.0.0 to 70.70.255.255 while network 70.70.0.0/24 includes the range 70.70.0.0 to 70.70.0.255. There you can see that 70.70.0.0/24 is part of 70.70.0.0/16 and you can't give it to a different customer.
Don't stop after you've improved your network! Improve the world by lending money to the working poor:

[SOLVED] Trying to understand the "size on disk" concept

Hi all,
I was trying to understand the difference between "size" and "size on disk".
A google search gave plenty of results and I thought I got a clear idea about
it.. All data is stored in small chunks of a fixed size depending on the
filesystem and the last chunk is going to have some wasted space which
will *have* to be allocated.. Thus the extra space on disk.
However I'm still confused.. When I look at my home folder, the size on disk
is more than 320 GB, where as my partition is actually less than 80 GB, so
I guess I'm missing something.. Could somebody explain to me what does
320 GB of 'size on disk' means?
Thanks a lot in advance..

Hi all,
Thank you for your replies.. My file manager is indeed pcman fm and
indeed it seems to be an issue.. In b4data's link the last post reads:
B-Con wrote:
FWIW, I found the problem. (This bug is still persistent in v0.9.9.)
My (new) PCManFM bug report is here: http://sourceforge.net/tracker/index.ph … tid=801864
I submitted a potential patch here: http://sourceforge.net/tracker/?func=de … tid=801866
Bottom line is that the file's block size and block count data from the file's inode wasn't being interpreted and used properly. The bug is in PCManFM, not any dependent libraries. Details are in the bug report.
Since PCManFM is highly used by the Arch community, I figured I should post an update here so that there's some record of it in our community. Hopefully this gets addressed by the developer(s) relatively soon. :-)
I guess that pretty much explains things.. And I think I did understand the 'size on disk' concept
anyway
Thanks again!

Trying to understand hashCode( )

Hello again, I'm trying to understand the hashCode( ) method. I have a textbook which describes it this way:
"A hashcode is a value that uniquely identifies an individual object. For example, you could use the memory address of an object as it's hashcode if you wanted. It's used as a key in the standard java.util.Hashtable[i] class."
Please forgive me if this emplies that I may be a bit slow with this, but this explanation is too vague for me to grasph what's going on here. Can someone thoroughly explain (in a non scientific way), how and why this method is used?
Thanks in advance.

I thought the examples I provided might give you an idea why the hashCode method is useful. I'll try one more brief one, and if that doesn't connect that spare wire to the light bulb over your head, then I'll have to agree with schapel and suggest that you study up on your CS theory.
This will be a really crocked up example, and you could skirt some of the issues with better design, but it's a valid example nonetheless.
You run a greenhouse or an arboretum or something. You've got 25,000 Tree objects (forget their subclasses for now). Trees have properties like species, name (I don't know why you'd name a tree--just bear with me), location, age, medical history. You're going to put your Trees into a java.util.Set, so you've got a collection with one reference to each tree. However, you're getting overlapping subsets of your trees from various sources--that is getAllElms() returns some trees that are also in getAllOlderThan(10). You need to combine all those results into a 1-each collection of Trees.
When you go to add an Object to the Set, the Set has to first check if that Object is already present. The Set implementation could iterate over all its elements and call equals() to see if that Object is already there. Or, it could first get the hashCode (let's say you've implemented hashCode to return the xor of the species and the age). So, maybe 100 out of your 25,000 trees are 50 yeard old Elms. Internally, if the Set implementation keeps a mapping from hashCode to an array of Trees with that hashcode, then it only has to copmare to those 100 trees that match, rather than all 25,000.
As I said, this is a cheezy example. One problem is that if trees are mutable, this Set implementation won't work, since the Set won't know that a Tree's internal values (and hence, possibly, its hashCode) have changed.
Is is making any sense yet?
Okay so please help me understand this rudimentary,
logical reason for wanting to use a hashCode( )? Say
I create a top level class called "Plant.java". Now
from that class I create a subclass called Tree.java
from which several other subclasses and objects are
created. Help me gain a basic understanding of why
and how the hashCode( ) method might be beneficial.
(lol... I feel sort of like I've opened up a cool new
electronic toy, I'm standing here with a "spare wire
in my hand wondering what the heck this part is
for?")
Thanks again for your help. I really apprecitate it.

Hi Bret,
Sorry it's taken me a bit of time to respond, but please find below a run-down of the WS-I related problems I spotted in your WSDL document. The first few are related to the import error you saw, and there's a few others that I'll also discuss. Apologies in advance if you've already spotted and corrected those.
I'll use line numbering based on the formatting of the WSDL and XSD that you supplied.
BP2417 (the one you asked about)
The line number in the error is a red herring. There are two problems here:
- WSDL document, line 29: You're using the XSD type string unqualified - it should be xsd:string.
- WSDL document, lines 8 and 13; schema, lines 3 and 4: The namespaces you're using don't match. Either change the namespaces in the schema to be http://Messages.xsd, or change the namespaces in the WSDL to http://www.bret.org/S3test/Messages.
BP2202
You should declare UTF-8 or UTF-16 encoding when creating WSDL or schema documents. The easiest way to do this is to go to Tools|Preferences, and set JDeveloper's default encoding to either UTF-8 or UTF-16.
BP2032
WSDL document, line 26 and 43: The name attribute of the fault should read SigFault, not sigFault, as WSDL is case-sensitive.
WSDL document, line 44: You should use a soap:fault element, not a soap:body element, to bind a fault, thus:
<soap:fault name="SigFault" use="literal"/>
BP2012
WSDL document, lines 17 and 20: Message parts in a document-bound service like this one should reference XSD elements and not complexTypes. What you need to do is define two elements in your messages schema whose types are SigReplyMessage and SigRequestMessage respectively, and then reference those elements from the WSDL.
WSDL document, line 38: The value of the parts attribute should be Keys to match the name of the part child of the RequestSignature.
WSDL document, line 41: The value of the parts attribute should be SigAndExp to match the name of the part child of the ReturnSignature.
WSDL document, line 44: The value of the parts attribute should be faultMessage to match the name of the part child of the SigFault.
BP2115
WSDL document, lines 17 and 20: The names of the elements should be sigReplyMessage and sigRequestMessage and not SigReplyMessage and SigRequestMessage, again because WSDL is case-sensitive.
WSDL document, line 30: The element attribute of the part references xsd:string, which is not an element but a complexType. You'll need to add an element declaration to your schema, which is of type xsd:string.
I've included corrected versions of your WSDL and schema below, I hope this helps. I also note you've posted a few other messages related to WS-I and WSDL, I hope I've managed to cover those in this message too.

Alan.

Trying to understand WDS

Hi all,
I'm using three AirPort Extremes to form a WDS. For the sake of brevity, I'll abbreviate their function and MAC addresses as:
Main14
Relay07
Remote2C
All three airports are run in Bridge mode.
Main14 is at the north end of my home. It is connected by ethernet cable to my DLink router. Main14 is set up as the WDS Main and it has been told that there are two remotes, Relay07 and Remote2C.
Relay07 is at the south end of my home. It has been told that the main WDS is Main14 and that there is one remote, Remote2C.
Remote 2C is in an outbuilding south of my home. It has been told that the WDS main is Main14.
I'm puzzled by two things:
1) If I pick up my MacBook, fire up Airport Utility and open three config windows, one for each Airport, and click the wireless client option so I can see what clients are being served by each Airport, and beginning at the north end of my home, I start walking south. When I'm next to the main WDS, I see that Main14 is serving the MacBook at a 54 rate. As I walk away from the main toward the relay (and even further south, the remote), the rate drops. I walk past the relay and the rate to the main keeps dropping. I get out to the outbuilding and I see the MacBook transfer from the main to the remote, Remote2C, and the rate goes back up to 54. The MacBook never transfers to the relay. Why not?
2) Going back to Airport Utility, and again with windows open for each Airport and looking at wireless clients, I can see the three Airports talking to each other. As a typical example,
Main14 sees client Relay07 at rate 11 and also sees client Remote2C at rate 1.
Relay07 sees client Main14 at rate 54 and also sees client Remote2C at rate -1.
Remote2C sees client Main14 at rate 18, but does not see Relay07 at all.
I don't understand two things here. Why doesn't Remote2C see Relay07 as a client? The relay is much closer to the remote than it is to the main. Second, how are any two units talking to EACH OTHER at different rates? If Main14 is talking to Relay07 at 11, shouldn't Relay07 be talking to Main14 at the same rate? But it isn't; Relay07 is talking to Main14 at 54. This doesn't make sense to me.
The practical reason I'm asking this, beyond simply trying to understand how the WDS works, is that my wireless connection in the outbuilding is very erratic. One moment I've got a full strength connection, the next I'm utterly disconnected. So I'm guessing that something isn't quite right here. But I don't know what, and I don't really understand how the system is working, so troubleshooting is a bit of a challenge.
Thanks for any help!

Hi Brian,
I'm having exactly the same problem, with the slight difference that I'm living in a flat and that the distance between WDS main and WDS relay is 4 meters (with direct line of sight) and the distance between WDS relay and WDS remote is 5 meters... My flat is built around an 'L' shaped corridor with main, relay and remote being each at one point of the 'L'.
Tried also to scan for used channels and took one of the free ones.
Can anybody help?
Thanks,
Buebeli

Trying to understand PersistenceContextType.EXTENDED

Hello,
I'm trying to understand the PersistenceContextType.EXTENDED setting. It is my understanding that when I put this in my class, it means that the container managed transaction will span multiple method calls.
I have a stateful bean:
@Stateful(name = "StatefulContainerSessionEJB")
public class StatefulContainerSessionEJBBean implements StatefulContainerSessionEJB, StatefulContainerSessionEJBLocal {
@PersistenceContext(unitName = "Model",
type = PersistenceContextType.EXTENDED)
private EntityManager em;
// implied REQUIRED transaction
public void createAddress() {
try {
// create a new address
Address addr = new Address();
//... set addr fields
System.out.println("Persist addr at: " + addr.getStreet());
em.persist(addr);
System.out.println("Persist of addr complete");
} catch (Exception ex) {
ex.printStackTrace();
// transaction should still be alive here
@Remove // this is what causes the transaction to end
public void cancelTransaction() {
System.out.println("Transaction rolledback");
em.getTransaction().setRollbackOnly();
And in my main code I have:
StatefulContainerSessionEJB statefulContainerSessionEJB;
public String createAddressThruStateful() {
System.out.println("Create Address Thru Stateful Button hit....");
try {
final Context context = getInitialContext();
statefulContainerSessionEJB = (StatefulContainerSessionEJB)context.lookup("StatefulContainerSessionEJB");
statefulContainerSessionEJB.createAddress();
} catch (Exception ex) {
ex.printStackTrace();
return null;
public String cancelPartTimeTransaction() {
System.out.println("Cancel Address Thru Stateful Button hit....");
try {
statefulContainerSessionEJB.cancelTransaction();
} catch (Exception ex) {
ex.printStackTrace();
return null;
First question is: am I using the Stateful bean correctly in main? i.e. its a class level variable and get instantiated in the createAddressThruStateful call.
My second question is: when I run this code, my address get commited to the DB at the end of the createAddress() call. I didn't expect this to happen.
Please straigten me out.
Thanks,
Chris

please tell me what the inout in this coode means:A parameter that supplies input as well as accepts output is an INOUT parameter.

Trying to understand iMac 10.6.8 better and find out if someone is spying on my computer.

Would like to find out if my computer is being spied on. Trying to understand info in "About my mac" means. Came across something in software Extensions...MACFramework: It says: Version: 10.8.0, Get Info String: MAC Framework Pseudoextension, SPARTA, Inc, 10.8.0, Kind: Universal,

What does this mean?
How/Where and What do I look for to see if someone is spying on my computer? And if so how do I remove it?

The Mandatory Access Control Framework is part of OS X, and is not spyware.
If you want to know if someone is spying on your computer, install Little Snitch. It will tell you when anything new is trying to send something outside of your system.

Hello, World - trying to understand the steps

Hello, Experts!
I am pretty new to Flash Development, so I am trying to understand how to implement the following steps using Flash environment
http://pdfdevjunkie.host.adobe.com/00_helloWorld.shtml
Step 1: Create the top level object. Use a "Module" rather than an "Application" and implement the "acrobat.collection.INavigator" interface. The INavigator interface enables the initial hand shake with the Acrobat ActionScript API. Its only member is the set host function, which your application implements. During the initialize cycle, the Acrobat ActionScript API invokes your set host function. Your set host function then initializes itself, can add event listeners, and performs other setup tasks.Your code might look something like this.
<mx:Module xmlns:mx="http://www.adobe.com/2006/mxml" implements="acrobat.collection.INavigator" height="100%" width="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
Step 2: Create your user interface elements. In this example, I'm using a "DataGrid" which is overkill for a simple list but I'm going to expand on this example in the future. Also notice that I'm using "fileName" in the dataField. The "fileName" is a property of an item in the PDF Portfolio "items" collection. Later when we set the dataProvider of the DataGrid, the grid will fill with the fileNames of the files in the Portfolio.
<mx:DataGrid id="itemList" initialize="onInitialize()" width="350" rowCount="12"> <mx:columns> <mx:DataGridColumn dataField="fileName" headerText="Name"/> </mx:columns> </mx:DataGrid>
Step 3: Respond to the "initialize" event during the creation of your interface components. This is important because there is no coordination of the Flash Player's initialization of your UI components and the set host(), so these two important milestone events in your Navigator's startup phase could occur in either order. The gist of a good way to handler this race condition is to have both your INavigator.set host() implementation and your initialize() or creationComplete() handler both funnel into a common function that starts interacting with the collection only after you have a non-null host and an initialized UI. You'll see in the code samples below and in step 4, both events funnel into the "startEverything()" function. I'll duscuss that function in the 5th step.
               private function onInitialize():void { _listInitialized = true; startEverything(); }

Trying to understand Android OS updates delays

This is not another hate mail, it´s more about trying to understand the facts and motives regarding the OS updates (or lack of).
Hopefully this material will arrive at someone from Sony with enough power to do something about it.
Ever since I can remember, Sony has been THE brand for electronics. I can´t remember a TV or VCR in my house that it wasn´t Sony, and they lasted for LOTS of years.
When a couple years ago I finally had the money (and the need) for a Smartphone, i chose the X10 Mini, which is a great little phone from a great brand, but it´s stuck at Android 2.1... which makes it a crippled android nowadays...
It really bothered me the lack of OS updates, so I chose to buy a Galaxy Nexus, but it´s really expensive in my country. So my second option was a Galaxy Ace 2, but they haven´t arrived to my country yet, so I went with my third option: Xperia Sola, knowing beforehand that it´s a great phone, a great brand, but I might get slow OS updates.
I bought it about 10 days ago when I saw they were starting to roll out the updates.
10 days later I still don´t have my update. And not only that, but I don´t see much light at the end of the tunnel...
I found a thread with the SI numbers that were updated, and there were a bunch on Oct 1, another bunch on Oct 4, and one code on Oct 8, and no other update since...
I also read that those who did get the update, were having bugs with the OS, and also found threads from other Xperia models, whose updates began rolling 3 months ago, and there is still people who hasn´t gotten the update...
As a customer, and a owner/CEO of a small company, I have a really hard time understanding how a HUGE company like Sony can be making such mistakes...
I have been thinking objective reasons, and I can only think of one. I know it´s a wild guess, but I´m starting to think that our salvation might be the very thing that means our condemnation: CYANOGENMOD!!!
Think about it: Why would Sony spend more money hiring twice as much programmers, when they can make only one update per phone, and sit down and see how CM releases begin to appear, for all tastes and needs. And... IT´s FREE!!!
Also, if there is a software related problem (way more likely than a hardware problem), then the CM developers take the fall, instead of Sony. And I´m beginning to see custom OS installers that are more user friendly, so it might be something that they take in accout when neglecting OS updates.
If that´s the line Sony is following, it´s a very risky move and it won´t work. Sony Mobile will crash and burn, but it´s still a better business plan that "let´s get lazy and make ULTRA slow updates so we don´t spend a lot of money programming".
If you can´t afford more programmers, stop including so much bells and whistles and make your OS near vanilla. Include a couple of Xperia menus, a custom theme and voila!
The main reason I wanted the Galaxy Nexus is Vanilla OS, which means inmediate OS updates. Sony on the other hand, takes a year or two to release it after its launch. If they release it at all...
Another though... why not stop making that many different phones! Really! There are like 5 Xperia models i can´t tell one from the other... even with specs side by side!
You are trying to make too many phones and you are failing with all of them! (Software and software updates are also part of the phone, one of the most importants...)
I know hiring programmers is expensive, but you are sacrificing one of the most expensive values for a company EVER: Customer credibility! Which as you know better than me, takes years to create.
If Apple had problems with carriers and code aprooving and stuff, they might get away with it, becouse they alone have all the devices. If iOS 6 is delayed a few months, it´s delayed for everyone, and besides Apple fanboys rarely complain about Mac products, but Android is a more independent and educated market.
I´m not saying that Apple users are ignorant, not at all, but I´m pretty sure most iPhone owners don´t even know what processor or how much RAM their phone has. They just "swallow" the Apple Way of Life. (it´s a good phone becouse Apple says so).
The Android user on the other side, because of the fragmentation of the market, has many brands and models to choose from. An Android user about to buy a new phone will most likely go online looking for different models, specs, reviews in webs and forums...etc.
You can´t say "I don´t know how HTC and other companies get their updates so soon, but we take a lot more becouse Google and the Operators must aproove the code.", because there are many other brands that have exactly the same difficulties or more, since they are smaller, and we can SEE online that they are indeed delivering solid and relativly fast updates.
Did we miss something? Does HTC use Witchcraft to get their code aprooved?
My underlying point is this: You are getting lazy... VERY lazy with software programming for your phones, and WE KNOW IT!
It´s not the "difficulties" you claim, becouse every brand has those difficulties.
This isn´t 1999 you know. We are in the information age. If you lie to us and tell us that your phones have the latest OS, I can go online and see that you don´t (Hello!!!). If I see that the company lies to it´s customers, I will stop buying their products. If I´m so dissapointed with how Sony handles OS updates and their customers queries about it, then I want for the first time ever to sell my Cell Phone becouse I´m not happy with it, or the brand behind it.
We also live in the "Here and now" age. You can´t expect your customers to read about new Android releases on news and blogs, and wait YEARS with arms crossed waiting for their update... The world doesn´t work like that. Not anymore at least...
It´s not a matter of how many recources you have, it´s about how you use and balance them. GIVE MORE IMPORTANCE TO SOFTWARE UPDATES! IT´S WAY MORE IMPORTANT THAT YOU THINK! LISTEN TO YOUR CUSTOMERS!!!
You guys are Sony are smart and design great products, but you are not GOD! You are not our wife, no one has sworn alliagence to you.
If you stop giving us good products and start lying to us, we hate you and stop giving you our money. Simple as that.
My sola is beatiful, I love the design, the screen, the hardware... but it hasn´t been updated yet to 4.0, not to mention 4.1, which REALLY is the latest version... so stop advertising that your phones have the latest Android OS, unless you want angry customers switching to other companies, which you are getting.
I also read some stories that Androind 4.0 was announced for the Xperia PLAY, and then it was called off... Do you have any idea how pissed I would be and ripped off I would be if I bought my phone based in that information and then you say it won´t be available?
Well, actually right now my possition is worse, since you SAY you will update my phone, but you don´t say when, and I read online about people still not getting their updates months after the rollout started, so I´m in the limbo right now...
As a company, one of the worse things you can do is calling your customers stupid, and when I see the answers you give in this forum, then I feel insulted. I feel like they are talking to an idiot or ignorant person with the so called "diplomatic" answers, which are basicly empty excuses for not doing your job right.
You gave us the frikking CDs, DVDs and Blu-Rays!!! Don´t tell us you can´t tweak an already built OS in a year!
I really hope you change their OS update policies really soon, before you lose the already small cellphone market share you have, or at least change your P.R. and C.M. policies towards a more open one.
We all are humans and make mistakes, but we customers really appreciate honesty and truth.
Have an open conversation with your customers! Don´t lie about your shortcomings! Accept then and ask the community to help you solve them, ask them what they biggest problems are, what features are most important to them, how often do they expect updates... LISTEN TO THEM!!
"Succes is a meneace. It tricks smart people into thinking they can´t lose."
Ps: Nothing personal with the mods from this forum, I´m not killing the messenger, I know that you can ONLY give the info you are allowed to give, and even if you wanted, you probably don´t know the answers yourself, since you work in the Communications department, not Developement or anything technical, and if you can't give any given info, then they probably won´t give it to you either... My message is to the company as a whole. I just hope you will be a good messenger and give this to whoever needs to read it.

My bad, it´s closer to 40 the number of phones released hehe
I know it´s all about money, and I know Sony is obligated to neglect users who haven´t given them money after an x ammount of time. However, it´s not a matter of making the phones obsolete earlier, so the users want to buy a new phone faster and therefore getting more money.
A person will buy a new phone when he/she has the money to do so and wants to do so.
It´s not a matter of WHEN. It´s a matter of WHAT.
The question is not "When will that user buy a new phone?", but rather "When that user buys a new phone, whenever that is, what phone will it be?"
I have a love/hate relationship with Apple. I would never use a iPhone. I would love having any Mac, if someone gives it to me, but I would never spend my harn earned dollars on such an overpriced piece of hardware over general principals.
However, i do recognice that Steve Jobs was a business genius. Weather you like or love his ideas and methods, he turned a garage project into the biggest company in the world, with a market value higher than Exxon with 1/3 of it´s assets.
Apple is a money making machine, and that is where the "hate" part of my relationship comes from.
However, it surprised me a lot to see that they released iOS 6 for the iPhone 3GS, released in 2008!
That get´s you thinking, that inside all that "SELL NOW" culture Apple is, they also support their older devices that people bought years ago but can't buy a new phone now. However, when they can do it, it will surely be another iPhone. Because they FEEL that the company listens and cares for them.
Also if you jump from iOS 6 on the 3 GS to a brand new iPhone 5, the transition will be virtually non-existant, except for Siri and a couple of features.
However jumping from Android 1.5 or 2.1 to Jelly Bean, might not be so easy on some users, making them more likely to give iPhone a shot.
Since they have to adapt to another phone anyway, they might as well try the apple...
And for old users, it gives people a sense of continuity and care about the user. Otherwise we feel like being kicked out of a restaurant right after we payed the bill.

WARNING:IP: Hardware address '02:bf:0a:d0:00:2a' trying to be our address

Hi,
When my system boots up the following error message is prompted:
WARNING:IP: Hardware address '02:bf:0a:d0:00:2a' trying to be our address
I perused documentation and it states that this occurrs when the ATM lane device is set to promiscuous mode by running snoop -d lane0. The corrective action to be taken should be to not ket the ATM lane device rin in promiscuous mode & not to ignore the warning.
What I want to know is how to implement the resolution?
Thanks!

Ok, my mistake.
So that PC is also trying to use 192.168.0.1.
And it must be doing arp broadcasts on the LAN.
Solaris should probably be ignoring them since it has an 10.x.x.x address on the lan. So it shouldnt care about 192.168.0.x addresses on the LAN.
Only on the crossover network.
But apparently it cares anyway.
So I suggest you change the cluster heartbeat addresses to something else thats less likely to be chosen by random computers on your lan.
Or figure out why the PC is trying to use 192.168.0.1. It could be someone running vmware or virtual box.
Or vlan you lan, so your critical servers arent sharing a network with random poorly configured PC's.

Trying to understand OIM - Please help

Hello All,
I am pretty new to OIM, just trying to understand how OIM works. For the past 4 years I was in Sun IdM and planning to switch over to OIM.
I read some documentation, I think OIM will perform basic provisioning and it contains out of box connectors to do basic provisoning. I have some questions can anybody please help
- Sun IdM uses Express language to develop custom workflows or forms, in OIM to develop workflows which language did you use, is it Java or any other language?
- If I want to provision users on AS/400, HP Open VMS or AIX systems, how can I do that I don't see any out of box connectors for these resources, so in order to integrate these resources do we need to write our own custom connectors?
- If the out of box connector does not support a specific function on a resource what are the options do we have? for example if the AD connector does not support to delete the exchange mailbox, how your going to perform this in OIM? Do we need to write a Java code for this?
- How much Java coding is necessary in OIM?
- Is OIM supports role based provisioning?
Please share any information.
Thanks in advance.

Sun IdM uses Express language to develop custom workflows or forms, in OIM to develop workflows which language did you use, is it Java or any other language?
- JAVA
If I want to provision users on AS/400, HP Open VMS or AIX systems, how can I do that I don't see any out of box connectors for these resources, so in order to integrate these resources do we need to write our own custom connectors?
- If OOTB connectors are not available then you'll have build you own connector as per Target Resource.
If the out of box connector does not support a specific function on a resource what are the options do we have?
- You'll have customize their connector as per your requirements or write your own
How much Java coding is necessary in OIM?
- We can't calculate how much java. It's totally depends on requirements how much code you'll ahve to write. But everything will be done using Java only.
- Is OIM supports role based provisioning?
Here Group represent Role. At a small scale it supports. But for large scale you'll have to use Oracle Role Manager as you do in Sun Role Manager.

What happens when you change your address in your iTunes account? You also have to have a payment method associated with the USA, For example gift cards are restricted to the country of their purchase.

Trying to understand, being prompted the file compression rules on saving, or not

Hello,
I'm trying to understand something, could I ask for your help, please ?
After working on a jpg file, when I want to save it, still as jpg, with my Photoshop CS5,
- sometimes photoshop will just save the picture, and it's done
- sometimes photoshop will show me the compression dialog, "JPEG Options", in which I can choose the compression ratio, the format options (baseline, baseline optimized, progressive), and have an estimation of the total file size
While not being prompted any dialog is simpler, and I'll then simply assume Photoshop decides to retain the current image's compression and format rules, I must say I like to be in control, and I'd like to know under what form the file is being saved without having to resort to the much more complex "Save For Web" menu.
Please, would you know WHAT "triggers" the appearance of the JPEG Options when we close/save a jpeg file, in photoshop ? What makes this menu not to appear, what makes it appear ?
If there are trivial file operations/changes/filters that necessarily trigger its appearance when we want to save, something like that ? I've tried a variety of these, but I still can't figure it out, sometimes it shows in the end, and sometimes it doesn't.
Thank you very much if you can help me
Kind regards,
Oliver

@ c.pfaffenbichler
These are images from various sources, not just one.
I'm deliberately excluding Save For Web, this completely re-processes everything.
My purpose, precisely, is to know when photoshop takes the decision to retain the image's "rules", and when photoshop decides to pose us the question, how do we want it saved.
Simply taking a jpeg image, doing stuff on it, and hitting control-w to close the window, and seeing if it will be an
- «OK, sure, do you want to save ? You clicked OK to confirm you wanted the changes saved ? Good, now it's closed» or a
- «please sir, how would you like your image saved, tell me the compression ratio and the format options, thank you»

UTL_HTTP.end_of_body Exception Error. Trying to Understand the Reason Why?

I have the following PLSQL Function that returns a End_of_body Error. This started when we migrated from 10g to 11g. It is simple enough to capture so the error does not stop the Function Flow, but the error causes the OCI driver in OBIEE to error, which prevents the use of OBIEE IBOT to execute. Trying to understand why this error is occurring..not sure if we have a permissions issue on the UTL_HTTP Package or what?
Anyone seen this problem in 11g? Suggests on resolving would be great. Thanks.
