XControl publish subscribe?

• Flex publish / subscribe does not public IP address

  I installed the last Flex Express LCD on top of ColdFusion 8 enterprise demo installed as JRUN/multiserver and got it all to work when you run directly from the server using the "' http://127.0.0.1:8300 / samples". " However, when I run outside with public IP address of the server, then everything works except for samples of publsh/membership push. They just hang and impossible to subscribe. Any ideas? What is a restriction on the LSCDS Express or the CF8 demo version? Or maybe a port problem? We have all ports closed except for those needed. There is an additional port that is to be opened in addition to 8300? Thanks for any help.

  I think I found the problem. It seems you must have port 2037 open for RTMP to work e-mail with sample apps. This port is closed on our firewall and I suspect that's why I'm having a problem. I'll get my network guy to make the change on Monday and then I'll try it again. Probably that it will solve.

• Account publish and subscribe to SOA Suite

  Hello

  
  

  the event driven network Publish and subscribe how do I know that it uses MQ or QA or JMS . ?

  Thank you

  Below are the main advantages of NDA instead of JMS Messaging:

  To interact with the SOA components via events EDN

  Typing with XML support inherent in the fort.

  Easy to use: simple type definition event, configuration of publish/subscribe (DTC) and you are ready to deploy/run.

  No need to manage objects JMS administered, for example in queue, connection factories, etc. - This is true in 11 g. This is true also in 12 c scalability becomes a necessary concern unless an additional heading of JMS with change of the event-to-JMS mapping.

  Publishers of PL/SQL (database) (if based on QA) supported.

• Issue of publication/Subscriber ETL

  I have a question about the use of publish/subscribe CDC with ETL on Oracle 10 g. Is the part of logic on the part of the Subscriber ETL code? In other words, when the Publisher is notified of a record of the change and sends the record to the waiting area, then calls the Subscriber. Is the Subscriber that implements the ETL logic that treats the recording before being sent to the DW/Dim tables? Something like this stream:
  Target database source-> change table/publication-> Subscribe view/ETL-> database

  Mark this thread as answered, you will find this option in the upper left corner

• Databases

  Are there aspects that I should take when binding data to a project?  I have first considered a database of basic XML but was interested in using BlaseDS framework.  Its all about the processing time!

  Thank you

  BlazeDS is a server application that would be remote to the client application that can reside on the PB.  BlazeDS is one of several implementations of servers available on the market to manage remote objects and mechanisms available in the Flex/AIR of publish/subscribe framework.  So yes, it is 'available' in regards to the client API, but BlazeDS is just an implementation to choose for the component server-side Exchange data between the client and the server (and a database).

  If you do not need 'real time' data exchange and that you are not proficient with interfacing of BlazeDS (and similar), you could be ripping out more of a paunch.  If you do not need to Exchange data with a server, there are other options.

  Hope that helps.

• Software components UCCE

  Hello

  IAM new environment UCCE (have little knowledge and worked in UCCX) and now iam in need to learn more about the company. My company is ready to provide me configuration lab company but they need of requirement as BOM for UCCE.

  When I did I got this link from cisco:https://www.cisco.com/web/partners/downloads/765/download/atp/ucce_lab_design_d3.pdf

  so, based on what I have prepared the general requirement as follows:

  Cisco® Unified ICM - a stand-alone server in MCS
  Cisco® Unified IP IVR - a stand-alone server in MCS
  Cisco® Unified CVP - A standalone server in MCS
  CTI server - a stand-alone server in MCS
  CTI OS server - a stand-alone server in MCS
  Door input (PG)-(est cette passerelle sert uniquement à cet effet) device
  Cisco® Unified Communications Manager Pub
  Cisco® Unified Communications Manager Sub
  PSTN gateway
  WAN gateway
  Windows server with AD

  With the license needed for all

  Is it OK my doubt particularly on the CTI/OS Server is this component of software that can be installed on the same machine with CVP/IVR/ICM, or is it a stand-alone server. What about a PG?

  Thank you

  Hari

  Everyone has different ideas here.

  My strong recommendation is to use a big box - say a zone of high performance HP DL380G6 with 16 GB of RAM and run VMWare ESX. Then you can use install it CUCM and CUPS who know that they are on the virtual machines and licenses. There are huge benefits to having the entire system on VMS ESX through virtual appliances to make snapshots and make back - it's so easy on VMWare.

  But if your company doesn't have a VMWare ESX, then you must - a few boxes.

  I do not recommend to buy Cisco's MCS boxes because they are HP/IBM boxes priced at a premium. Just buy the HP or IBM box (of course, I recommend HP boxes).

  What you REALLY need to learn is a correct understanding and deep of the dual nature of the components of the ICM, then I strongly suggest Progger A, Progger B, AW/HDS. A Progger running recorder, the router and the agent PG (with a PIM for CUCM, a PIM for IP IVR and a PIM for CVP). The progger also manages CG (CTI server) and CTIOS (CTI Object Server). You want the separate domain controller.

  This is so four boxes.

  Now, a box for each CUCM, IPIVR and CVP.

  So we are up to 7 boxes.

  It's nice to have a pair of publish-subscribe, if you can afford it. But most do not do this in the lab, so I would pass it.

  You should get a combined bridge PSTN/VXML - CVP. Something like a 2811. You need an E1/T1 card of course and can detach calls for the CVP and CUCM/IPIVR off the a set of channels. 1 E1/T1 will be enough.

  So 7 boxes and a router.

  You also need a SIP Proxy, in my opinion, to get a good understanding of the works of CVP. It can work without a proxy, but this isn't something you would never deploy so you will not learn what you need. You used to be able to install a presence (CUPS) relying on the DLUs CUCM server and use it only for the SIP Proxy, but Cisco recently blocked in favour of the CUSP (SIP Proxy on a router). It is expensive and I don't know if there is a way to do a laboratory at lower cost.

• Difference between Oracle EDN and JMS topic

  Hi all

  Can someone explain in detail the difference between Oracle EDN and JMS topic?

  The only difference I see is

  JMS producer must specify the name of the topic to which the message is to go...

  the NDA does not specify where any point of termination (queue or topic), he just publish the event...

  Are there other differences? How to choose when to use Oracle EDN and JMS topics?

  Please, share your ideas...

  Thank you

  Oracle EDN also uses the subject or the database under.

  So there is no difference in low level technology

  However, the NDA is much easier to implement from the subject.

  EDN avoids you having to use create rubrics, create connection factories, creating adapters, update deployments etc. All this is supported internally in the NDA and is available out of the BOX for you. You simply set an EVENT and then publish / subscribe it.

  However, you can use topics when you have other subscribers of third party such as SAP, Siebel, because the NDA is strongly coupled with Oracle SOA, BPEL, mediator components.

• Why we use JMS instead of using HTTP/SOAP WebService

  Hello

  Why we use JMS/SOAP instead of using HTTP/SOAP HTTP being more good on the Protocol TCP/IP (why seller enjoy JMS)

  Why we use JMS rather than to use the direct database because the database JMS use internally to store its payload.

  I've read these post

  < http://Java.dzone.com/articles/performance-soaphttp-vs-soapjm > and

  < http://it.Toolbox.com/blogs/the-SOA-blog/Web-Services-http-vs-JMS-19110 >

  But in reality most of the things we can achieve in the two example

  Consider using SOAP http:
  
  • Externally facing web services (for example, customers or suppliers) ( ) in JMS also is good, that we can do )
  • For simple point-to-point and services stateless ( ) we have point to point in JMS queues using )
  • Where you need a thin client with no installation of MOM
  
  

  Consider using SOAP over JMS for:
  
  • High-volume distributed messaging ( ) Why for high volume JMS is required for HTTP based Web Service ? )
  
  • Asynchronous messaging (based HTTP web service can also be asynchronous and we can use the correlation machining inside()

  • Where a transaction limit is necessary in the middleware (which is operation limit, it is not possible with the basic HTTP web service ? ) )

  
  • Where the message consumers are slower than the producers (the location of that point in difference( )
  • Guarantee deliver ()that we can achieve in web service basic HTTP using the WS-Reliable messaging standard so how this point said difference( )

  • A one-time delivery of messages (what back "only once, sending a message" threat and is not possible with the web service HTTP based ? ) )

  
  • Publish/subscribe ( ) this mechanism broad casting can be done using HTTP based web service also if all applicant read only the recording of database ) (Same JMS use the internal database)

  
  • Distributed systems of peers who can sometimes be disconnected ( ) This also good for basic HTTP web service, we can use correlation sets (asynchronous service) then even if the following resource is not in service expect that it will be available and continue run more. so, how that pint is indicative of difference )

  
  

  Someone tell me really what is the real benefits or difference and why and where we use JMS Web service instead of HTTP based Web (real difference) service base

  
  

  
  

  Thank you

• The standardization of the distributed and unit-of-order ISSUE

  Hello
  
  I will in the following document and I have a few questions on this basis
  http://docs.Oracle.com/CD/E17904_01/Web.1111/e13727/uoo.htm
  
  1.
  Based on the above, if a unit-of-order jms message is sent to a uniform distributed topic, Weblogic sends the message that one of the members of destination topic. Is it also correct to assume that messages will not be transmitted to other members of topic destination even if the redirection policy is set to "REPLICATED"?
  
  
  2.
  In addition, the document above (http://docs.oracle.com/cd/E17904_01/web.1111/e13727/uoo.htm#i1041061) mentions a limitation when using uniform distributed QUEUE and unit-of-order with hash routing function. That is to say
  + "If a member of queues distributed has a unit-of-control partner and is inaccessible, the producer sends the message will throw a JMSOrderException and messages are not routed to other distributed queue members. +.
  
  However, the document does not mention what would be a behavior under the same scenario when using uniform distributed TOPIC (the use of hash-based routing)? will it be the same behavior with uniform SUBJECT distributed as well? Can you please clarify this
  
  
  3 Please refer to the section of the document http://docs.oracle.com/cd/E17904_01/web.1111/e13727/uoo.htm#i1044686, where it is said that + 'unit-of-Order messages are processed one at a time' +. This means that any operation batch parameter specified on the MDB (listening on the subject) will be ignored and that a message will be processed at a time?
  
  
  Kind regards
  Arif

  I somehow implies that the behavior of publish/subscribe violates the contract PUA? In an RTD or a PDT, messages for the same AUP can of course be copied on multiple subscriptions. The ranking of the AUP of transformation within a given subscription is maintained.

  That said, there are only two cases where I remember off-the-top of my head that PUA command can easily be violated:

  -As you mentioned, no transactional section BMD in compatibility mode that max-beans-in free-pool greater than 1 more run in a thread pool with more than 1 thread available in the MDB. IIRC, compatibility mode is not supported with Stdp, this restriction does not apply to the Stdp. It's good to know you already noticed this in the docs.

  -Distributed queues that allow "transfer queue". I know it's documented too, but I don't remember where.

  I do not remember the existence of special restrictions on the use of PUA in combination with the PDT. Hash-based routing applies on the way of the shipment and has the same behavior on a like on a TDR or a UDQ TMP. Ditto for the track of basis of Routing Service.

  Kind regards

  Yes; or, more generally,.
  (1) GG can "capture" (consume) JMS messages and create GG tracks... and
  (2) GG can use existing trails and deliver (send messages) to JMS

  That also means you could do: database-> trail-> JMS-> path-> database. Which would give you a publish/subscribe architecture w / GG, rather than the many-to-many replication.

  ("Change data capture" terminology database is a bit strange when it comes to e-mail, but you get the idea). For historical or technical reasons, the JMS "capture" may also be referred to as the JMS VAM, and "delivery" of JMS is also going to be sometimes referred to as the JMS (Java) user exit (or java-EU).

  OK, with the terminology of the road...

  Extract from the process of mgr GG + (original) +.
  extract JME911

  table GGS. VIKSTK;

  Is very good, although, technically, the user exit before the next version 11.2 implementations do not handle the trails in "Add mode".

  From GG v10.x, default track format changed to "overtype mode" to "Add mode". User-output are automatically garbage in the track when the tracks are in "Add mode"; the tracks should rather be in mode "crush." (This "mode" is a term of full-audit of the recovery, which means that if there is a upstream "abend", then after that the restart process, target track data are added, rather than overwrite the record current, incomplete, potentially damaged.)

  In other words, in more simple terms: technically, trails should be in 'overtype mode. You can do this either by specifying "overtype mode" or saying the trails are "format version 9.5".» Actually, it does exactly the same thing. Note that this "mode" is not a problem that there is a "abend" upstream. And the 'problem' is not really predictable; Basically, from the point of view of the output of the user, there are duplicate in the trail that is simply processed data. But enough about that. Moving...

  Also, on the top of my head, I don't know that there is never a reason for a file to "throw" in "extract."

  Also... What is with complete & backslashes paths? : - )

  So this is what you have technically expected to have:

  Extract from the process of mgr GG + (updated) +.
  extract JME911
  GGS@bidb username, password ggs12345

  OverwriteMode RecoveryOptions
  rmthost 10.180.182.77, mgrport 7817
  megabytes of dirdat/JM, rmttrail 100

  table GGS. VIKSTK;

  And as for your pump running the JMS service:

  Excerpt on GG for JMS + (original) +.
  extract JE911
  sourcedefs E:\GoldenGate11gMediaPack\JMS\V22254-01\ggs_Windows_x86_Generic_32bit_v11_1_1_0_0_078\dirdef\vikstkFF.def

  CUSEREXIT E:\GoldenGate11gMediaPack\JMS\V22254-01\ggjava_ue.dll CUSEREXIT INCLUDEUPDATEBEFORES PASSTHRU
  TABLE ggs.vikstk.

  As "best practices", follow these steps:
  

  
  
  1. Copy your *.properties in dirprm. Keep all the config in dirprm. It makes things easier to bear.
     
  2. using ' / ' instead of '-' becomes much more important here. Some of these paths are read by Java, and some are read by native code (C/C++) depending on the platform. Native code on Windows is ok read a path like 'C:\path\to\foo', but if you pass it a path to the Java application, then you must use either: (1) "C:\\path\\to\\foo" or 2 "C:/path/to/foo." The same is true for relative paths; the advantage of relative paths is you don't have to deal with the "C:" or "E:" prefixes, and prm and property files are independent of the platform.
     
  3. You can eventually put all the "Properties" in one file, while defining GGS_USEREXIT_CONF and leaving GGS_JAVAUSEREXIT_CONF unset. The only reason for which you want to define the two is if you have files of separation of property, several pumps and he wants to avoid the duplication of your files.
     
  4. your pump is running the JMS user-exit must spend 100% of the output of the user data. Technically, this is necessary in particular situations, but it is best to always do (must be careful about the filtering as part of a whole operation). You can write filters in Java for more refined filtering.
     

  The problem here is:
  

  
  
  1. the path of the property for GGS_JAVAUSEREXIT_CONF file is read from Java (or, if not defined, GGS_USEREXIT_CONF is read from Java), which means that you must use "/" and not "------" as the path separator. (Just never use "\", and're you good to go in the configuration of your GG).
     
  2. in the javaue.properties file, check that classpath is set correctly; It should include "dirprm", ggjava.jar and your implementation of JMS 3rd party-online javawriter.bootoptions=-Djava.class.path=dirprm:ggjava/ggjava.jar:lib/activemq-all.jar... etc... + (* NOTE! * use colon ":" as a separator in path on Unix and semicolon ";" on Windows!) +
     
  3. (maybe) make sure that the JAVA virtual machine is in the path (windows) or LD_LIBRARY_PATH (unix) before the Bishop. Under windows, this is the path to jvm.dll, unix/linux, this is the path to libjvm.so (and dependencies, if necessary)
     

  This error (means that the ggjava.jar is not found below). (The ggjava.jar take care of all the other jars in resources/lib/*.jar of loading). This should be in {GG_HOME}/ggjava/ggjava.jar. In other words, the "ggjava" directory should be in the same directory as 'extract '. In addition, the "ggjava_ue.dll" (or libggjava_ue.so) are GG_HOME (the same as dir "extract").

  Error occurred in javawriter.c [269]: error occurred (except Java): loading Java class: java.lang.NoClassDefFoundError: com/goldengate/atg/datasource/UserExitMain

  in fact, he has no UserExitMain file in the place where he is looking.
  I expect that this file is provided in the zip, but this is not

  The UserExitMain is inside a pot inside ggjava/resources/lib/*.jar. By adding ggjava/ggjava.jar to the classpath variable, each GG jar is automatically added to the classpath. (This way, "com, goldengate, atg, datasource" is inside a jar).

  See above...

  And here's a complete example:

  -Folder: dirprm/javaue.prm

• Conditionally send messages to several consumer

  How much better would accomplish this requirement?
  
  I have a system that produces messages
  Several systems may want to consume these messages
  
  I want the producer to send messages under condition
  
  In one case maybe I send message even to each consumer
  However, in another case maybe I only want to send a message to consumers and B
  
  It would be OK if I could score some messages to some consumers, and then consumers only recover these messages designated for them. But I don't think this is possible as such any flag, that the consumer would have to read once, it consumes the message and the bed, I don't think that there is a way for the queue to make this decision for them.
  
  So, it sounds like what I need is a hybrid point-to-point and publication / subscription
  
  I want a universal way to send messages to one or more consumers of conditionally, and the conditions are dynamic.
  
  Any suggestions?
  
  It takes a TPP with a queue for each application?

  You can do this with publish/subscribe and message filters. all consumers subscribe to this topic, but all of them use a filter such as (not exactly the syntax):

  "receiver_id = 'ALL' GOLD receiver_id = 'me" ".

  (where 'me' is unique for each subscriber). Then, you can broadcast to anyone with a message including the receiver_id property value 'ALL', or send a message to a specific Subscriber by setting the receiver_id this unique ID of consumers (you will need to send the message once for each consumer in this case). (you may be able to get away with a single message by receiver_id a list separated by commas and do something like "reciever_id LIKE" %, me, %' "", just make sure that your list separated by commas has commas at the ends).

• Model real world observer in the CF?

  I'll put together some course material for my companions to desktop on design patterns in ColdFusion. I'm having a hard time coming up with an real realistic example of what situations would be a good candidate to be resolved by a model of an observer in a CF web app.  There are certainly many examples of how to implement the model in the CF, which is great, except that I don't really find a lot of scenarios that the examples are based off of meaning in a web application environment - many of them are based on Java examples where references to the observer/observable objects are maintained for life (session) of the application.

  In a CF web app, this seems as it would only make sense if you were dealing with Singletons for objects of the observer and the observed so that their references to exist outside the scope of a single page from loading.  However, I'm having a conceptual block to come with a pressing problem on why you need an observer as part of a single page model CF.

  I'd like to hear other devs CF come into contact with any real world examples.  I'm sure that I could probably something like LogBox refer to as an example of the behavior, but I was hoping for a very simple example that I could use, put a code in front of my developers.

  Thanks in advance!

  A few years ago, when I, too, was grappling with design patterns, I found a few useful items from Microsoft MSDN. One of them, the paper by Doug Purdy and Jeffrey Richter on the model of the observer, is very good and contains an example of the stock market.

  I don't see how you arrive at singletons for observers. More on that in a moment. The essence of the observer model exceeds the programming language, syntax or implementation details. All what you need to know is in the scheme of traditional patterns (which I reproduce here of Wikipedia on the model of the observer).

  

  Indeed, the diagram itself is very suggestive and can help you find examples of your own. There are 2 main roles, the observer and the object. There is a dependence as little as possible (i.e. loose coupling) between them. This allows either to change their internal mechanisms without affecting the other.

  At its most simple, with only 2 roles, the observer observes the subject. The subject has to turn standby on a dynamic resource which the observer wants to know.

  In most practical applications, there is more than one observer interested in the dynamics of resources. The subject has the responsibility to inform each of the resource, or any change observer. To be able to do so, it maintains a list of observers. Each observer has a responsibility to be notified by the subject. That's all. It is said that any system that works in this way, apply the model of the observer.

  The example of most common practice is a newspaper publisher and the subscribers. The Publisher made the object, the observer subscriber, and news from the dynamics of resources. In fact, much like Hoover became synonymous for vacuum cleaners, so too has Publisher-Subscriber become a synonym for the model of the observer.

  Let go of the need for a coupling between the observer and the object means that none of them should use shared or global variables. These variables create tighter form of coupling possible. So back to the issue of giving observer using a singleton or not. I wouldn't do it. Absolutely not. A singleton is an application-scope variable, so shared and would be pairing.

  To keep the loose coupling, it is usually recommended to implement the observer and the object as an interface. Classes representing the actual topic and concrete observer would then be the attention of implementers of the respective interfaces. Each of these concrete classes could radically change its internal structure, and the outside world would not notice. This is because the respective interface for the observer and the subject remains intact.

  Now to the Enigma of a practical example of the observer model in the context of a future ColdFusion page. In the model of the observer, the subject is of necessity an earpiece, listening on a dynamic resource object. Therefore, the ColdFusion page that represents the object must be a listener CFC. There is already an example built into ColdFusion. It's the DirectoryWatcher event gateway. Use inheritance to adapt to the CFC to include features in order to maintain a list of observers in the database. Include, for example, requests to inform observers by email whenever a change occurs in a directory.

• LCC versions

  Is there a standard place to look for download and see companies low-cost publication release notes?

  I am currently on 1.2.5. Are there any known issues with this version using the standard webcam pod with audio Publisher/Subscriber? Problems during the interaction with existing servers of the low COST airlines?

  I'd be on the latest version? Last time that I update, there were some things which has broke out which caused a lot of trouble for me. People report problems with the latest version? I have a forthcoming milestone in the next few days I need to be as stable as possible. Would you recommend the upgrade?

  Hello

  Is take a look at the file of release notes for the latest version. Currently his 1.3.5. In the release notes, you'll also see the patches. There were two releases after 1.2.5 i.e. 1.3.0 and 1.3.5.

  Ideally, you should be on the latest version that we try to maintain backward compatibility.

  Yes, there were a few corrections and optimizations for audio and video in 1.3.0, and some more coming in the next version.

  The next version, we will try to put a file of version right in the top folder of the SDK downloaded so that it becomes even easier for you to watch. So if you open the SDK Navigator application, it automatically detects if there is a new version, and if so, ask you if you want that.

  Hope this helps

  Thank you
