Director Flash 8 xtra breaks shared object and onSync

This one has driven me insane for days, but at least now I
know what the problem is. It's really a Director-Flash8 xtra-FMS
problem, but I figure the best chance for a solution is posting it
here.
The problem is this: The Director Flash 8 xtra update messes
up remote shared object connections to FMS applications. The
Management Console debugger does not show any SO properties ("no
data"), and only the "clear" onSync event fires. The old Flash 7
xtra worked/works fine. To illustrate, I've tested the following
code in the Director message window with both the v8 and v7 xtra
(if you know Actionscript and not Lingo, it's still easy to figure
out what happens here). It basically creates and connects a remote
shared object on FMS:
rrr = newObject("SharedObject")
nnn = newObject("NetConnection")
sss = "rtmp:/apptest01" -- app on locally running FMS
er = nnn.connect(sss)
put er
-- 1
fff = rrr.getRemote("tester", nnn.uri, true)
put fff
-- <flash object>
er = fff.connect(nnn)
put er
--1
-- so it's all good until here. onSync callback works with
"clear", etc, but...
fff.data.foo = 55.5
put fff.data.foo
-- 55.5... but only shows in Mgmt Console when using the v7
xtra...
-- when using the old flash7 xtra,
-- debugging the FMS app and onSync events works correctly,
-- but when using flash8 xtra,
-- debugging the FMS app shows "no data" for this shared
object. foo = 55.5 should be there.
-- also, onSync events no longer fire after the initial
"clear".
If I translated this into actionscript and ran it in Flash 8
vs Flash 7, etc, would I get the same problem? I'll try that next,
but it took me a while to get this far. Is it simply a matter of
permission or firewall setting? Or is it something just broken with
the Director flash 8 xtra?
Thanks

As of just last week, Adobe can replicate the problem and is
"working on it". I don't anticipate a shockwave-flash-xtra update
to come out of this, but perhaps they can identify some other
work-around. If you can avoid using "success" onSync events and
don't need shared object debugging, then FMS works with
Director/Flash 8 xtra... but this may be a symptom of yet more bugs
that I haven't seen.
I'm stopping development on my FMS/Director project until
this is resolved... I may need to crack open the old Multi User
xtra.

FMS Remote Shared Objects and PHP

Is there a way to access remote shared objects from PHP ?
I've created an a/v chat application, once a user is connected to it, it creates a remote shared object that indicates that the user is online. I want to find out if a shared object exists via PHP to let other users, who are not connected to the flash application, know what's the user's status.
Thanks!

All the things you want to do are typical Shared Object's functionalities. I've already created a couple of huge projects myself using Shared Objects functionalities, so I can say with the full responsibility that all the things you want to do can be done very easily using those classes.
Basicaly, if you want to build your app using SO, there are few options available for you on the market. First, and the best I guess, will be Adobe's Flash Media Interactive Server. It's only disadventage is, that it's quite expensive - but it's worth it's price, believe me.
If you don't want to pay for it, you can also use a free and open source Red5 server. If it's only the "text-chat based" functionality you want to implement, with a typical video streaming, this one should be enough for you. Although, there could be some problems waiting for you if you wanted to create a full video-chat based application. Take a look at the FMS vs Red5 comparision, which maybe will help you decide - http://www.riafreaks.com/. On the first page of this URL there will be an article I'm talking about covering this topic, as well as a sample guide on how to connect FMS to PHP code, which will let you work with any database you want.
To be honest, if I understood your problem correctly, than Red5 should be enough for you. It works great with Shared Objects, it's free, and it gives you the whole Java API server side - so you can connect to the database very easily. And it also let's you create and manage Shared Objects client side, as well as server side. Although, believe me that even if you're not a Java developer yourself, you won't have to write even a single line of server side code. You can create, update and destroy Shared Objects using only your Flex clients - it'll suite all your needs in the context you've written.

Local Shared Objects and multiple SWFs: mutexes necessary?

I will have multiple SWFs on a single web page, each reading
and writing the same SharedObject, which may be up to 100K in size.
Will I need to create some sort of mutex scheme to ensure that one
SWF isn't writing while another is reading, or do all SWFs on a
page essentially run as a single-threaded application?

>1) I don't think a SharedObject.flush is synchronous.
I believe it is, as long as you're not attempting to write
more data than the user has set for the Local Storage limit.
http://livedocs.adobe.com/flex/3/langref/flash/net/SharedObject.html#flush()
You'll note that flush is described this way: "Immediately
writes a locally persistent shared object to a local file", and if
it returns "SharedObjectFlushStatus.FLUSHED" that means that "The
shared object has been successfully written to a file on the local
disk". So I'd say that the normal operation of flush() is
synchronous. However, the SharedObjectFlushStatus.PENDING state
means that we've exceeded the limit set by the user, and are
waiting for them to allow or disallow it. I believe (strongly) that
that's the only case in which a netStatus event is sent.
Do you read this differently?
As far as multiple SWFs running as cooperative or preemptive
multitasking processes, I'd really like to know the answer, but it
probably doesn't matter. The more I read and think about this, the
more it seems to me that Adobe has to prevent simultaneous reads
and writes to a single Shared Object from taking place, as one use
of it that I've read about is to share data between SWFs. For
example:

Shared object and different application servers - how to resolve this issue

Dear SDN Members,
We are occuring a big problem. We create a shared object in a program and after we call in an another one. In central system architecture, it is working well. But on a distributed architecture (4 application servers), we have a dump some times. In fact, the read of the shared object can be occured in the AS 4 but the share object has been created in AS1.
How to manage this problem to avoid this dump ?
Dupplicate the shared object in the application servers ?
Encapsulate different calls with RFC link to only one AS ?
Any parameters on server or share objects ?
Thanks a lot for your help,
Points will be given to right or good answers.
Br,
Aurélien

What is the dump you are getting ?
AFAIK, "Shared Memory"(SHM) is an area defined in the app server. I am not sure if you can access SHM of a different app server (as in your case trying to access SHM of AS1 from AS4). [http://help.sap.com/abapdocu_70/en/ABENSHARED_MEMORY_GLOSRY.htm]
In this case you can opt for "DataBase Clusters". Relevant ABAP statements: [IMPORT|http://help.sap.com/abapdocu_70/en/ABAPIMPORT_MEDIUM.htm#!ABAP_ALTERNATIVE_4@4@]/[EXPORT|http://help.sap.com/abapdocu_70/en/ABAPEXPORT_DATA_CLUSTER_MEDIUM.htm#!ABAP_ALTERNATIVE_4@4@] FROM/TO DATABASE.
Hope this helps.

Shared Objects and IOS 5.0+

So, I need a straight answer. Can I use Shared Objects for my game, or will apple fail me for using them? Will Shared Objects be backed up with iCloud?
Thanks,
diss.

Boat,
From what I have found if your IPA/APK/SWF is the same name then shared objects data should retain.
So if version 1 of your app was
AppleApp.ipa published from a swf by the name of AppleApp.swf
then when you update on your final publish save your swf and .ipa under the same name
Dont do this
First version is
AppleAppV1.swf published out to AppleApp.ipa
Second version is AppleAppV2.swf published out to AppleApp.ipa
The swf is what the shared object is associated with so keep that the same from update to update.

Security issues for Flash cookies, Local Shared Objects, .sol files

Good day, all
I just found out a bit about flash cookies from Wikipedia and http://epic.org/privacy/cookies/flash.html
I was wondering if there was a security issue with these (as opposed to privacy issues)?
It seems easy enough to prevent them being stored or delete them after they are set.
Thanks,
Hugh

Hello Patricia,
You wrote,
I came to this forum to see if I could find out how to delete adobe's flash cookies
You have to do it online via this website.
Macromedia's Website Storage Settings panel
Note: As the site says, the dialogue box is not an image, "it is the actual settings manager"
I just tried it out and deleted the flash content from How Stuff Works, then revisited the site (How Stuff Works) and it didn't add it back, so it seems to work as stated.

Flash Log In From with Shared Objects

So i want to create a flash log in and registration form for my flash game. THis game is played on your local PC not in the internet and i am using AS 2.0. So on the registration from i want to have two input text fileds: username and password. When you click on register the data from those fields to be saved as Shared Object and then on the log in when you type something in the log in fields (again two fields : username and password) the data that you wrote in those fields to pass trough the saved data as shared objects and if those two are the same then the log in is successfull if i want the movie to go on a certain frame whare it says access denied. pls help

if you use the obviously named textfields:
var so:SharedObject = SharedObject.getLocal("login","/");
if(so.data.username==undefined){
//need to register and assign:
so.data.username=usernameTF.text
so.data.password=passwordTF.text
loginBtn.onRelease=function(){
if(so.data.username==usernameTF.text && so.data.password==passwordTF.text){
//successful login
} else {
//login failure

Query Time Out and Shared Objects

Hi,
I have 2 questions.
1) from st22 i can get the list of users and time out information. But how can I find related query which has been time out by that user ?? as of now i was getting query information from st22 by getting abap program name which starts with "G" and find related query for that from the table rsrrepdir. But recently it is happening that i get abap program which starts with "G" from st22 time out but its not giving me any query information in RSRREPDIR table or by t-code se38.
can anyone guide me how can i get query info from st22 ? we have so many time out occuring in production have to trace that and improve the query performance.
2) 2nd question is - how can i get list of queries which are having shared objects like variables, templates, key figures, structures etc...
is there any specific table or t-code which provides that? we have to delete some queries in prod. but before that we want this list.
A.H.P. I am counting on you extensively for help coz i have seen that you reply to everybody. and i have asked same question in another forum at SDN but no reply !!!
waiting for help...

Hi Bhanu,
thank you for your prompt reply.
well, we dont have woorkbooks atall. we got the inventory list of all queries needs to be deleted in production. we are deleting very very old queries which are not even in used now. i know the variables and str. etc...remains but still needs to know how to find out the queries with shared object. i want that information in hands before i delete anything in dev. system and transport it to prod. so, i will have proof that i didnt delete anything important. hope you understands what i mean and why i need to know this !
i found few tables related to this but cannt relate them and get the info I need. RSRREPDIR, V_ELTDIR_TXT, RSZELTXREF,etc..
where used list in BEx gives us the webtemplates names nothing else. i meant not the shared objects. and if it is giving shared objects info then i guess i am not aware of it coz few queries i tried to check didnt get that info in "where used" list.
in metadata repository ?? i didnt get it!! how can i find queries with shared objects in metadata rep ?

Shared Objects

Not sure this is sound programming .. but I offer it up for opinion as it resolved an issue and seemingly works ..
The issue ..
Attempting to provide for "bookmarks" in an app w/ the Shared Object ..
Created the Obj in the maintimeline .. for the life of me I was unable to access the SO from a child MC .. e.g. parent.SharedObject.data. geneated errors
so I created a class object whose properties is the shared object and it worked ..

package{
public class GlobalVars2 {
import flash.net.SharedObject;
public static var UserStatus:SharedObject = SharedObject.getLocal("UserStatus");

First of all, I'd recommend to use smpatch utility to update your system. It is available "out of the box" on Solaris 10 and can be installed on Solaris 8 and 9 separately.
If you don't use smpatch, here are some tips for manual patching process:
I can only tell you about first two - libthread and libnsl. They both belong to the same package, SUNWcsl:
$ pkgchk -l -p /usr/lib/libthread.so
Referenced by the following packages:
SUNWcsl
$ pkgchk -l -p /usr/lib/libnsl.so.1
Referenced by the following packages:
SUNWcsl
Current status: installed
Now, to find out which patches are required, use 'showrev -p' command:
$ showrev -p | grep SUNWcsl
Next thing you do is search sunsolve.sun.com for latest versions of patches mentioned by showrev, download them and install with 'patchadd' command. This is rather painful process, so again, I recommend to use 'smpatch'.

Problem with shared objects synchoronization.

I encountered a small problem with shared objects.
I'm working on a program that creates chat rooms of a fixed
size of 30 users. When the 31th user comes, a new room is created.
The idea is that the client first connects to the first room
and checks if it's full by connecting to shared objects. If it is
full, connection is closed and process is reapeated on a new
instance of the application.
I use a function to connect to an instance, which takes as a
parameter a number (1 for instance room_1, 2 for room_2, etc). The
function itself creates the necessary Netconnection and
sharedObject objects.
If a room is full, Netconnections and sharedObjects are
closed and function is called again with another number.
I have no problem for connecting to the first room, but after
closing the first connection and connecting to the new room, there
seem to be some problems with the shared objects (especially,
OnSync doesn't seem to execute again after the connection to the
shared objects of the new instance).
I was wondering if you had any ideas what could cause this.
Is it the use of the same variable names for connecting at two
different shared objects?
Here is the function :
function initStreams(room) {
client_nc = new NetConnection();
client_nc.connect("rtmp://192.168.0.4/Elearning/room_"+room);
in_ns = new NetStream(client_nc);
in_ns2 = new NetStream(client_nc);
Replay_video.attachVideo(in_ns);
out_ns = new NetStream(client_nc);
out_ns2 = new NetStream(client_nc);
in_ns.play("my_recorded_stream");
users_name = SharedObject.getRemote("users_name",
_root.client_nc.uri, false);
users_name.connect(_root.client_nc);
users_language = SharedObject.getRemote("users_language",
_root.client_nc.uri, false);
users_language.connect(_root.client_nc);
users_picture = SharedObject.getRemote("users_picture",
_root.client_nc.uri, false);
users_picture.connect(_root.client_nc);
users_finger = SharedObject.getRemote("users_finger",
_root.client_nc.uri, false);
users_finger.connect(_root.client_nc);
I you need more info, I can post more of the code on the
forum.
Any help would be really appreciated

I don't see any onStatus events in the code you posted above.
If you're defining the onstatus event outside the function, that's
the problem. When you define the shared object, you also need to
define it's onStatus event handler.
Also, you really should wait for the onStatus event of the
netConnection before you connect your sharedObjects. If you try to
connect the SO before the netConnection is established, the SO will
never connect.

Modifying Dependent Shared Objects in Executables

I am attempting to perform the following operations on ELF32 format files:
1) modify the names of the NEEDED shared objects that are referenced by an executable after the executable has been built.
2) modify the embedded SONAME of a shared object file (adding one if it does not exist) after the shared object file has been built.
3) modifying the NEEDED shared objects that are referenced in a shared object file after it has been built.
The shared objects and executables are built from third party software that we have the source code for, but we do NOT want to modify the Makefile for each third party package each time we build a new version.
Of the three items, the one that is proving the most challenging is the modification of the executable files after they have been built.
Is there either a tool that enables me to modify these fields in the shared objects as well as the executables? Is there a way that I can re-link a shared object or executable file and then specify that modifications be made to the existing SONAME and NEEDED information?
(I have attempted unsuccessfully to use the elf library on executable files. Even relatively simple operations, such as modifying the length of the dynamic string section in which the NEEDED shared object is stored breaks the executable file.)

Hello Tomi,
First, thank you for taking the time to write such a well
though-out suggestion. Are you familiar
with the “LabVIEW Object-Oriented Programming: The Decisions Behind the Design”
document? I think the reason we chose to implement a ‘by
value’ strategy, is that is more in line with the LabVIEW programming paradigm
of dataflow, and would make sense to most of our LabVIEW users.
I think your suggestion is interesting, and it does
highlight the need to think outside of the conventional LabVIEW box and look to
some of the innovative things other languages do. However, I think we all agree that
synchronization takes careful planning and extra work for the programmer. Even with an ‘ideal’ solution I see no way
around this. For LabVIEW users today,
one great way to get synchronized ‘by reference’ semantics with your objects is
to use a single-element queue to pass your object. The queue itself is passed ‘by reference’ and
is inherently synchronized! The does
have the disadvantage of adding one more small layer of complexity to your
program, but some complexity would have to be introduced in any situation. The other disadvantage with this is that it
is not always an intuitive way to implement your program and requires some
amount of LabVIEW knowledge before one would generally come across this
technique.
In any case, I appreciate the time and effort you put in to
your suggestion. Please make sure that
you submit the suggestion formally through the NI Product Suggestion Center so
that it can be reviewed by some of the decision makers here.
Thanks again,

Shared object not writing?

I have a client who has a video that is to only play once when a user visits. So I created a shared object to create a param that the video has been played. It works perfect locally and on my live test site. However when the client posts it on his ning website in the header it doesn't work. The strange thing is that live and locally on my server you can see the shared object and it's size through the advanced tab in Flash's privacy settings. When on his server the size just has two dashes? Ideas.

Well they have some crazy system for uploading to the server. When it finishes uploading it works fine except for the writing of the shared object. Does ning.com have the write permissions for flash disabled? Is that possible?
Here is what the client said about the upload process:
"Not yet. Here is what I have done.
1. Click on SWF and then click save to desktop
2.In order to upload SWF to NING platform you have do it through a blog
entry to get its own URL. Once I get that I copy the "http://.... all the
way to .swf" and insert in the script for the flash header in what is called
Analytics. This process has worked fine up until now and appears to load
the new SWF just fine.
3. When I refresh pages or switches tabs it still repeats
4. I have gone into Explorer Internet options and cleared all history but
still no change."
I assumed he was still looking at the old file since it wasn't working but he was looking at the new file with the shared object. Here's a screen shot of the flash privacy settings panel:

How to Get property values from Shared Object in client's load event - Very urgent

I am using shared object to share data between two users. First user connect to shared object and set some value in shared object. Please consider that second user has not connected with the shared object yet.
Now when second user connects to the server and try to get that property set by first user, he could get shared object but could not get properties of Shared object set by first user. I observed few times that Second user can get these properties within "Sync" event between two users. But I would like to get these values for Second user in any stage (i.e. in load event etc.). Whenever Second user tries to get the property of Shared object, the object will reset the actual property value and then return reset value.
Anyone faced such issue while using shared object between two users. If so, I would appreciate if you could let me know your suggestions for following questions:
1) Is there any way to get all the properties of shared object before sync event called, as I want to get it immediately when second user connect to the application and perform next task based on the values stored in shared object.
2) Is it possible for second user to check whether any property has been set by first user? So that second user can use the property instead of reset it.
Any kind of help would be greatly appreciated.
Thank You.

How can i use the shared object already present in the system from java.

explanation:
Actually there are shared objects present in the jdk which is used by java itself.I want to know if i can use the methods in any library file(shared object) which is already present in the system.
Or the question can be put this way how does the java call the native methods? (Can we do that explicitly) in our code.

It isn't entirely clear what you mean by 'shared' objects and what the relationship with these shared objects and calling native code is.
There are no shared objects in the Java language, only the java platform.
The platform system properties are exposed via the System class (java.lang package).
You are free to create your own shared objects by using static member access or some other mechanism.
Your access to methods in any of the API's is dictated by the access type you have, normally public being the only completely open access allowing complete visibility.
You can call native methods, thats what JNI is for. Calling native methods in classes other than your own is generally done using the API provided by the developer(s) of those classes.

Issue with Shared Objects

Hi all,
I've a problem with a program working on Shared Objects technology.
We have a Job, scheduled in 18 parallelism, and each one writes into the SHM controlled by a SHMA Class.
At jobs ending, a program reads content from the area and sends an automatic e-mail with the results.
Everything works well if the writer program is executed on-line.
Otherwise, in background, seems that nothing is stored in the SHM.
Here's the code executed by the writer program:
FORM shared_memory_access TABLES it_fehler STRUCTURE rpfausg.
DATA: errors_reference TYPE REF TO data.
DATA: lx_pterl00       TYPE REF TO zcx_pterl00_collector.

I cannot explain why multiple jobs do not populate the area...

Hi Rob,
if your requirement is to have many (18) active processes all updating the shared object, and very few simply reading the shared object, then versioning is probably not what you require.
Versioning allows readers to continue to attach and read the active shared object instance while the updater gets their own instance of the shared object. When the updater does a detach_commit the old instance becomes obsolete and all new requests to attach will be diected to the new instance. The old instance will be cleaned up by garbage collection once all of its readers have detached.
If your programs primarily attach for update then you will decrease performance with versioning because a new instance needs to be created at every attach for update.
Perhaps you should just retry the attach for update after a small period of time has passed?
If, on the other hand, you do have lots of other readers of the shared object you may well still find that it is more efficient not to have versioning. I build a web shop catalogue using shared objects and found that versioning severly hampered performance. This was because, once the catalogue was initialised, updaters were pretty rare but readers were constant.
BTW make sure you keep the locks on the object as short as possible. Do all your preparation work first, then attach for update, update, detach as quick as possible.
Cheers
Graham Robbo
