Passing between app servers.

Hi,
Is it possible to pass the session attributes from one application server to another securely?
I have a user validated in one application running in a app server. I need to pass in the user information to another application running in another app server securely. How do I do that?

Jndi communication between app servers?

Hi all,
I'm quite familiar with J2EE and its communication architecture. In the past, I haven't had the need to communicate from one app server to another (just all web/applet clients to the central app server). But now I need to :)
Is there a way to communicate (synchronously) between app servers on different machines that aren't clustered? Clustering is not a possibility.
I know JMS is an option, but JMS is asyncrhonous. I also know you can't create server sockets in an app server because the J2EE spec disallows this approach, so forget about client/server communication via sockets.
This would be my ideal solution:
Server A does a jndi lookup for a bean on server B. Server A gets this reference and works with it just like any other J2EE client to server B.
Does JNDI allow you to do lookups to other namespaces outside of the current namespace on server A?
Can this even be done?
Thanks,
Les Hazlewood

Yes. It's possible. For one of my applications, I have three HP-UX servers that run i2 software on them, but for different business units. I have a J2EE application that does a little bit of everything for the i2 applications. Since the business logic is the same, with only the business dept differing, I deployed 3 instances of JBoss, each running on their own server. My user's log into one of the applications, doesn't matter which, and if they request a service (EJB) that needs to run on a different server, my webapp makes a connection to that server and uses the remote EJB to do the work. It's very possible and an excellent solution.
The solution will depend on which J2EE server you're using.
Here's a class I use to retrieve the InitialContext I need for my application:
package com.cibavision;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
import java.rmi.RemoteException;
import java.util.Properties;
public class CibaJNDI{
   public static InitialContext getInitialContext ( String server ) throws javax.naming.NamingException {
      Properties p = new Properties () ;
      p.put(Context.INITIAL_CONTEXT_FACTORY,
             "org.jnp.interfaces.NamingContextFactory");
      p.put(Context.PROVIDER_URL,
             "jnp://" + server + ":1099");
      p.put(Context.URL_PKG_PREFIXES,
             "org.jboss.naming:org.jnp.interfaces");
      return new InitialContext (p) ;
}Using this class, I have logic in my application that calls for the appropriate server, something like this:
if businessA then use server1
if businessB then use server2
if businessC then use server3
I then call for my InitialContext, request my EJB, and I'm off and running. No clustering, it matters which machine I'm on (I have to read extract files, etc.)
Works great. We are also a weblogic shop, but I haven't made any calls to weblogic from outside my J2EE app yet, but it should only differ by the hash attributes you pass to new InitialContext( props ).
Hope this helps,

Apache / JRUN setting up trust between two app servers

Hi,
I have two applications running on Apache web server and JRUN app server.
How can i setup a trust domain between the two jrun app servers so that the user doesnt have to enter authentication credentials in both the servers when forwarded from app server 1 to app server 2?
Thanks in advance

I researched that we can do a "fake" authentication by using cookies. Has anyone does this before? Can somebody guide me on this?

"Portable" way to do message passing between threads?

(I posted this on the Apple Developer Forums already, but since that forum is only accessible to registered and paid iPhone developers, I thought it would be nice to put it here as well so as to get some more potential eyeballs on it. I apologize if this kind of "cross-posting" is not kosher/is frowned upon around here.)
Hey everybody,
"Long-time listener, first-time caller," heh.
I've been working for the past 2-3 months on my very first iPhone app. Actually, what I've been working on is a framework that I plan to use in an iPhone app of my own but which I am also trying to write for the "lowest-common-denominator" so that I (and others) can use it in other apps written for both Mac and iPhone.
Not only is this my first time writing an iPhone app, it is my first time writing for any Apple platform. In fact, it is my first time using Objective-C, period. I cannot stress this enough: I am a "n00b." So go easy on me. I also have not worked with threading before this, either, on any platform, so the learning curve for me here is rather significant, I'm afraid. I am NOT afraid of either taking the time to learn something properly OR of rolling up my shirtsleeves and working. However, on account of my experiences so far, I am finding myself (not to flame or anything!) quickly becoming frustrated by and disillusioned with not so much Objective-C itself, but the Foundation frameworks.
So with that said, read on, if you dare...
The basic idea behind my project is that the framework I am writing will present an API to developers which will allow them to write client apps that interact with a particular network appliance or network-aware embedded system. I already have my basic set of classes up and functioning, and the framework works to my satisfaction both on MacOS and iPhoneOS. The platforms I am targeting are MacOS X Tiger 10.4 and later, and iPhoneOS, and up until this point, I've managed to keep a codebase that works on all of the above.
What I wanted to do next was add some multithreaded goodness to the mix. (Woe is me.) I have asynchronous network socket I/O working within the main thread, and it, in fact, works a treat. In my test app on the phone, I've managed to keep the UI nice and responsive by using the main thread's runloop efficiently. But even though TCP async I/O works fine within the main thread, I want to be able to split out and offload the processing of any data received by the app from the appliance to its own thread. (It is possible, and even desirable, for an application using this framework to be connected to multiple appliances simultaneously.)
My idea, in order to try to keep things as simple and as clean as possible, was to implement a wrapper class that presented my other main class as an "actor." So, rather than instantiating my main class, one would create an instance of the wrapper class which would in turn control a single instance of my main class and spawn its own thread that the network connection and all data processing for that particular connection would run within.
(I hope I'm making sense so far...)
Out of the gate, writing a subclass of NSThread sounds like the logical design choice for an "actor-type" thread, but because I was trying to maintain Tiger compatibility, I stuck with +detachNewThreadSelector:etc.
Once I decided to pursue the actor model, though, the main problem presented itself: how to best pass messages between the main thread and all of the "actor" threads that might be spawned?
I stumbled upon -performSelector:onThread:withObject:, and knew instantly that this was exactly what I was looking for. Unfortunately, it doesn't exist on Tiger; only its much more limited little brother -performSelectorOnMainThread:withObject: does. So I kept looking.
All of the pre-Leopard documentation, tutorials, and sample code that I read indicated that to pass messages between threads, I needed to basically pretend that the threads were separate processes and use the expensive Distributed Objects mechanism to get messages back and forth. Unfortunately, even if that WAS a desirable option, iPhoneOS does not have any support for DO! Grrr...
Finally, I thought I found the answer when I ran into a third-party solution: the InterThreadMessaging library from Toby Paterson (available @ http://homepage.mac.com/djv/FileSharing3.html). In this library, the author basically implemented his own version of -performSelector:onThread:withObject: called -performSelector:withObject:inThread:. Sounds close enough, right? And actually, it is pretty darn close. It's made to do exactly what it sounds like, and it does it in a platform-neutral way that works on pre-Leopard systems as well as iPhoneOS, using Mach ports instead of DO.
(...wellll, ALMOST. I discovered after I built a small test app around it that it actually isn't "iPhone-clean." The author used an NSMapTable struct and the NSMap*() functions, which don't exist in iPhoneOS, and he also implemented the handlePortMessage delegate method, but although iPhoneOS has NSPort, it DOESN'T have NSPortMessage. GAAARGH. So I took the time to replace the NSMapTable stuff with NSValue-wrapped objects inside of an NSMutableDictionary, and replaced the handlePortMessage method implementation with a handleMachMessage method, which took some doing because I had to figure out the structure of a Mach message, NO thanks to ANY of the available documentation...)
Once I started using it, though, I quickly discovered that this implementation wasn't up to snuff. My "actor" class and my main thread will be passing a ton of messages to each other constantly whenever there is network activity, and with InterThreadMessaging, I found that whenever activity started to ramp up, it would collapse on itself. This mostly took the form of deadlocks. I found a note that someone else wrote after experiencing something similar with this library (quoted from DustinVoss @ http://www.cocoadev.com/index.pl?InterThreadMessaging):
"It is possible to deadlock this library if thread A posts a notification on thread B, and the notification on B causes a selector or notification to be posted on thread A. Possibly under other circumstances. I have resolved this in my own code by creating an inter-thread communication lock. When a thread wants to communicate, it tries the lock to see if another thread is already using the InterThreadMessaging library, and if it can't get the lock, it posts a message to its own run-loop to try again later. This is not a good solution, but it seems to work well enough."
So I tried implementing what he described using a global NSLock, and it did help with some of the deadlocks. But not all. I believe the culprit here is the Mach ports system itself (from the NSPortMessage documentation for -sendBeforeDate:):
"If the message cannot be sent immediately, the sending thread blocks until either the message is sent or aDate is reached. Sent messages are queued to minimize blocking, but failure can occur if multiple messages are sent to a port faster than the portís owner can receive them, causing the queue to fill up."
InterThreadMessaging in fact calls -sendBeforeDate: and exposes the deadline option, so I tried setting a really short time-to-live on the Mach messages and then intercepted any NSPortTimeoutExceptions that were thrown; upon catching said exceptions, I would then re-queue up the message to be sent again. It worked, but Performance. Was. A. Dog. At least the message queue wouldn't be full indefinitely anymore, causing the main thread to block, but during the whole time that these messages were expiring because the queue was full and then being re-queued, either the main thread was trying to send more messages or the actor thread was trying to send more messages. And as far as I can tell, the Mach ports queue is global (at the very least, there is seemingly only one per process). The message would get through with this model...eventually.
JUST IN CASE the problem happened to be something I screwed up as I was rewriting portions of the InterThreadMessaging library so that it would compile and work on the iPhone SDK, I substituted in the original version of the library in my Mac test app to see if any of these problems became non-issues. I found that both versions of the library -- mine and the original -- performed identically. So that wasn't it.
Finally, in frustration I said, "screw it, I'm going to try it the Leopard way," and replaced all of the method calls I was making to InterThreadMessaging's -performSelector:withObject:inThread: with calls to Foundation's native -performSelector:onThread:withObject: instead, changing nothing else within my code in the process. And wouldn't you know: IT WORKED GREAT. Performance was (and is) fantastic, about on-par with the non-threaded version when only dealing with a single connection/instance of my class.
So, in the end, I was able to do nothing to salvage the InterThreadMessaging implementation of cross-thread method calling, and as far as I can tell, I'm out of (good) options. And thus my mind is filled with questions:
How is the Leopard -performSelector:onThread: method implemented? I'm guessing not using Mach ports, given that I didn't have the same blocking & deadlocking problems I had with InterThreadMessaging. Is it possible to re-implement this Leopard+ method in a similar manner as a category to NSObject under Tiger? Or is it possible, perhaps, to increase the size of the Mach ports queue so that InterThreadMessaging works at a sane level of performance? Or -- I'm getting desperate here -- is there any way that I could trick -performSelectorOnMainThread: to target a different thread instead? (I am assuming here that -performSelectorOnMainThread is implemented under-the-hood much like the new -performSelector:onThread: is implemented, but with a hard-coded NSThread pointer built-in to the code, and that the new method just exposes a more flexible interface to what is basically the same code. I'm probably wrong...) Is there another third-party library out there that I've missed that fits my requirements for being able to do message-passing between threads in an efficient and portable manner?
I refuse to believe that there is no way for me to maintain compatibility with all of the platforms I wish to support without having to resort to making preprocessor #ifdef spaghetti out of my code. And there SURELY has to be a better way of doing cross-thread message passing in Tiger without using Distributed Objects, for Pete's sake! Is this really how people did it for years-on-end since the dawn of NeXT up until the advent of Leopard? And if there really, genuinely wasn't another alternative, then what is up with the lack of DO in iPhoneOS?? Does Apple seriously intend for developers who have good, solid, tested and working code to just chuck it all and start over? What if there was some aspect of DO that previous implementations relied upon that cannot be recreated with simple -performSelector:onThread: calls? (I don't know what those aspects would be...just a hypothetical.) I mean, I can understand needing to write new stuff from scratch for your UI given how radically different the interface is between the Mac and iPhone, but having to reimplement back-end guts such as something as elemental as threads...really?!
I do laud the inclusion of the new method in Leopard as well as the new ability to subclass NSThread itself. But for those of us that need to support Tiger for one reason or another, some of these restrictions and omissions within iPhoneOS seem like rather pointless (and frustrating) roadblocks.
As I hope is obvious here, I have tried to do my homework before throwing up my hands and pestering y'all. If you have the patience to deal with me, please tell me what I am missing.
Thanks for taking the time to read,

Thanks again for your patience. Comments below.

It is pretty unusual that anyone would want to call perfomrSelector on any thread other than the main thread.
What I described in my original post was not a worker thread, but an "actor."
It is hard for me to answer this question because there are so many options available to do "message passing". The fact that you think there are so few tells me that you really aren't sure what you need to use.
I didn't say there were few options for message passing. I said there were few options for message passing that fit my criteria, which are that any potential solutions should both A) work efficiently and with good performance, and B) be available both pre-Leopard AND on the iPhone. -performSelector: ain't available before Leopard. Distributed Objects is overkill. Kernel Mach messages apparently have a high overhead, too, as my experience with the third-party library I wrote about in my original message shows.
...consider notifications.
I thought notifications couldn't be posted across threads, either. How do I post a notification to another thread's default notification center or notification queue from a different thread?
The notification center is owned by the process. Each run loop can listen for just the notifications it wants. You don't "pass" or "send" notifications, you run then up the flagpole for all to see.
I am aware of how to use notifications. The documentation for NSNotificationCenter clearly states that "In a multithreaded application, notifications are always delivered in the thread in which the notification was posted, which may not be the same thread in which an observer registered itself."
So, again, I don't see how one thread can post a notification in such a way that the observer's registered method is executed in another thread (posting notifications "across threads"). This probably isn't a big deal if you are using mutexes (assuming you don't actually care which thread carries out the task associated with the notification posting), but as I said before, this is not what I'm after.
I don't know what you are really after.
Allow me to attempt to explain a second time, in a more concise fashion.
My app will have multiple, persistent TCP connections open, one connection per remote device. The user will be able to select a task to execute on a particular device that we have a connection open to, and get back from the application real-time updates as to the progress or results of the execution of that task. In certain cases, the length of the task is infinite; it will keep executing forever and sending back results to my application which will update its display of the results every second that ticks by until the user STOPS that particular task.
This can be done simply using async I/O in the main runloop, sure. But if I were going to thread this so that I could be processing the results I've received back from one *or more* remote devices while also doing something else, given that I will only have one (persistent) connection open to any given remote device that I'm interacting with (that is to say, I won't be opening up a separate TCP session for every single task I want to execute on a single device simultaneously), it makes sense _to me_ to implement this as I've described: with every connection to each remote device getting its own thread that lasts for the lifetime of the TCP session (which could be the entire time the application is running, times however many devices the user wishes to be connected to while in the app). I won't be spawning a new thread for every task the user wishes to ask a remote device to do.
This is why (I think) I need bi-directional messaging between the main thread and each of these threads dedicated to a given remote device that we have an active session with/connection to. The main thread needs to be able to tell remote device X (which already has a running thread dedicated to it) to do task A, and then get real-time feedback from that remote device so that the main thread can be displaying it to the user as it is coming back. Same with remote device Y running task B, simultaneously. At any time during the execution of these tasks, the user needs to be able to tell my app to stop one of these tasks, and the main thread needs to send that message to one of the remote devices via that device's dedicated thread.
This is why I am talking about this in terms of the "actor model," and not the "worker thread model," because the former model seems to fit what I want to do.

Cannot get Telnet to work between two servers on same subnet

I need to test if communication is open on port 8444 between two servers.
I installed telnet client on a Server 2008 R2 server and telnet server on a Server 2008 SP2 server. I also manually started the Telnet service that was set to disabled on the SP2 server. I disabled the Windows firewall on both servers. They
are both on the same subnet so they don't need to go through any routers and I can ping successfully.
When I try to telnet to the remote server by typing telnet "ip address" 8444, I get an error that says "Could not open connection to host, on port 8444: Connection failed.
I tried other ports like port 80 and got the same error.
What else is needed to get this to work?

VMs have nothing to do with it, as long as there's network communication between the servers.
As I said, there must be a service or application listening on that port for it to respond. For example, try this:
C:\> telnet
When the telnet prompt opens, type in:
open mail.messaging.microsoft.com 25
If it works, you should see this:
220 CH1EHSMHS035.bigfish.com Microsoft ESMTP MAIL Service ready at Thu, 7 Feb 2013 00:57:33 +0000
That means that Microsoft's mail servers are LISTENING on port 25 and it responded. And note, telnetting to port 25 is a non-default telnet port, because port 23 is the default telnet port. When you type in a space and then a port number, you're telling
the telnet client to use that port.
That is the SAME THING if some sort of application or service is listening on port 8444 on that other server you're trying to telnet to. If there is no app or service listening, it will just time out.
And no, installing the TELNET service on that sercver will NOT answer to any port other than 23. The telnet service by default, uses TCP 23, unless you specify otherwise.
So once again, what service or app on that server is supposed to be listening on 8444?

Port forwarding between two servers from Same subnet

Hi,
We have a Cisco ASA 5520 Version 8.4(3). There exists a site to site VPN tunnel between us and a client and the client sends us the data to our local host/server 10.x.x.20 on port 52944. So 10.x.x.20 gets data on port 52944. We want to forward this data to a test server 10.x.x.21( same subnet IP) on port 52945. so basically I want to forward traffic from 10.x.x.20:52944 to 10.x.x.21:52945.
Is this possible. I am a new bee to the networking and still learning. Excuse me if this sounds silly.
I know we can add one more ACL in the VPN tunnel and add this test server IP in the ACL. but, then I have to ask the clinet to change their ACL too. I dont want to do this. So I want to wrok around it. Any help or suggestions is much appreciated.
Thanks in advance :)
This is my first ticket in the support community.

SharePoint Foundation 2013 - Search Configuration Issue - 2 App Servers and 2 Front-End Servers

Hi,
We have a SharePoint Foundation 2013 with SP1 Environment.
In that, we have 2 Front-End Servers and 2 App Servers. In the Front-End Servers, the Search Service is stopped and is in Disabled state and in the 2 App Servers in One App Server, Search is Online and in another Search is Starting but goes to Stopped sooon
after.
Originally, we had only 1 App Server and we were running our Search Service and Search Service Application in that. Now since the index location became full and we were unable to increase the drive there, we added one more App Server and now the issue is
Search is not properly getting configured in either of these App servers. What we want to do is run Search only in the new App Server, because we have a lot of storage space for Index locations here, but in the older App Server, not run Search at all. We
tried keeping the Search Service disabled and ran the below PowerShell Scripts, but none of the ones are working. These scripts are creating the Search Service Application, but the error of "Admin Component is not Online", "Could not connect
to the machine hosting SharePoint 2013 admin component" is coming up.

What is the difference between apps and applications?

I have an application that I've been running on my older Mac. Now that I have a new MacBook Pro, I have to reinstall new software that is compatible. When I go to the vendor website I see an application I can download or a link to the Mac App Store. Is an application different than an app? When should you download them from a vendor website and when should you go to the app store? Do apps end up in the Launchpad and an application in your Applications folder? I can't seem to find information on what is the distinction. Are they actually two different things? Any help would be appreciated.

No difference between apps and applications. If you download the app from the Apple AppsStore you have better security and a conveninet place to have all your downloads. Nothing wrong with downloading from a trusted developer though.
EDIT: Yes they will either wind up in your Download folder as a .dmg you will have to double-click on to install, or most app store apps will install to your Applications folder.

Workflows 2013 and SQL Report Services: Configure on Independent Servers or Existing App Servers?

Currently, my SharePoint 2013 Farm has Workflows 2013 and SQL Report Services installed on app servers, along with other applications. Workflows 2013 isn't working correctly (installed prior to my coming on board with the organization), I'm assuming it
is a configuration issue, but rather than re-configure, I've read that is recommended to be a standalone server. It was also recommended by a MSFT rep that our report services have its own independent server. Currently, Report Services is also installed on
an app server that runs other applications on the farm.
Has anyone had any experience with installing Workflows 2013 and/or SQL Report Services on independent vs. existing application servers?
Additionally, my existing application servers have 24 GB of RAM (I believe the recommendation for SharePoint production environments is 12 GB), should I plan for the potentially new servers (Workflows and Report Services) to also have 24 GB of RAM? Not really
sure if it will be needed if they have dedicated tasks.
Thanks for any input you can provide!

It entirely depends on load. WFM will work just fine installed on servers in the SharePoint farm. SSRS preferably should go on the end-user facing servers for better performance.
The questions you're asking are all "it depends" :)

2 App servers in farm will be auto failover and load balanced?

Dear all,
We are going to setup following SharePoint farm:
2 WFE
2 APP
2 OWA
2 SQL with shared NAS
We will have hardware load balance in front of 2 WFE. From my understanding, the 2 WFE will detect which APP server is available and send the request there.
Hence, if APP1 is down, all traffic come from both WFE will be directed to APP2.
But I am not so sure about the part about load balance. If all the 8 server instance are working properly, the new request come from WFE2 will be sent to APP1 or APP2? Or it depends on which service application is asking?
In addition, we planned to run all search components on APP servers. But the 2 APP servers are both 16GB memory which is lower than suggested specification. I am considering whether I can assign all the search workload on APP2 while all the other on
APP1.
Thanks.
Mark

Here is a good artcicle on how SharePoint load balances service applications:

Yes you can create APP02 as search server but then service apps will not be redundant , so it would be better to run all the service apps on both the servers and if you see any memory issues, then scale it later.
As per
http://technet.microsoft.com/en-us/library/651dba4d-8751-4bd8-9492-f2842b2e1177(v=office.15)#HW_Enterprise , 16 GB is recommended for application server so i think you should be okay unless there is very high load .

How can I switch between apps without going to home screen?

Is there anyway to switch between apps with one tap? (ie. without going to home screen first). Kind of like a command-tab feature.
Steve

Well, you can have one app that you can get to with a double push of the home button (set in settings which you want), but I think it's only your contacts list, or your ipod app. Still useful though.

How do I stop Firefox mobile from having to restart when switching between apps?

When I'm switching between apps, firefox takes 10 seconds to load up again. Why isn't it already loaded since I just had it up? The Opera browser doesn't do that.

Android automatically closes apps in the background when it needs more memory. To let Firefox run in the background longer, we will need to reduce its memory usage. We are continuing to work on this with each new version of Firefox.

Can you install the Office Web Application Server on one of the App Servers for SharePoint 2013?

Hi,
Is it possible to run Office Web Application Server (shows preview images for docs and allows Notepad, Word, Excel to work etc) on one of the SharePoint 2013 App Servers. I don't want to have to create a new server. It talks about setting
up a farm.
Better still how the feck do you switch this functionlity off - I always remember it being a pain in the arse. We accidentally ran the first part of the configuration on one of the SharePoint App Servers only to find out our subscription does not
have this download (bar stewards changed this Nov 2014 - just after started contract).
Help would be much appreciated as close to go live
Thanks.
John.

Hi John,
Please reboot the server at the very beginning and test the issue again.
Quote from you:
Problem is I get Internet Web Page cannot display the webpage everytime I click in a excel document, powerpoint document, notebook link or the preview
Please post the url in browser address here.
If you just executed the command below:
Add-WindowsFeature Web-Server,Web-Mgmt-Tools,Web-Mgmt-Console,Web-WebServer,Web-Common-Http,Web-Default-Doc,Web-Static-Content,Web-Performance,Web-Stat-Compression,Web-Dyn-Compression,Web-Security,Web-Filtering,Web-Windows-Auth,Web-App-Dev,Web-Net-Ext45,Web-Asp-Net45,Web-ISAPI-Ext,Web-ISAPI-Filter,Web-Includes,InkandHandwritingServices
It just install some windows feature to the current server, we can find it should be done before installing several server products.
Could you please verify if the command you executed is the same as the one above?
You could also go to local disk and check if there is OfficeWebApps folder under C:\ProgramData\Microsoft\?
If you check in Control Panel > Programs, is there any feature related to Office Web Apps?
If you have confirmed there is no Office Web Apps feature installed, please go to SharePoint document library settings, and make the document to open in client, does it work?

Going between apps they continue to reset. I can no longer do what I need my iphone for.

Going between apps they continue to reset. I can no longer do what I need my iphone for. I've looked for a solution and haven't found one. This seems to be a gigantic blunder in the latest evolution of iOS. I used to love iphone but now it's like a curse. Thanks for any help you can give.

Can you be more specific? What does "going between apps they continue to reset" mean?

Passing between app servers.
