Oracle tuxedo, what exactly?

Hi all
As I was assingned to work on oracle Tuxedo. I don't know what it is.
I realized that it is used as a wrapper for COBOL, C and C++. This is it, or is there anything else we could do with Oracle Tuxedo?


Thanks in advance,

Hello Rahul,

Tuxedo is an application server for non-Java languages. Specifically, this means that it provides a lot of facilities that help customers create and deploy business applications written in C, C++, COBOL, and with applications of SALT add-on written in Python and Ruby. As an application server, it provides containers to host your business logic written in these languages. It offers facilities for transparently distribute your application on a cluster of machines route and balance requests to load on the computers in the cluster and the servers within a machine. If "machines" fail or network links fail, Tuxedo routera automatically requests to the remaining available servers in the cluster, thus providing extremely high availability. When these resources are returned to service, Tuxedo will automatically start the use of these resources, so you get failover and failback. Tuxedo tends to be used where RASP (reliability, availability, scalability and performance) in the application. Smoking customers regularly achieve 99.99 percent and 99.999% availability for their applications with some clients running continuously for years without failure. As a highly optimized application server, Tuxedo can invoke a service in another process and get an answer in about 35 microseconds. That performance combined with Tuxedo clustering capabilities to be able to handle 100, in thousands of queries per second, as Tuxedo scales almost linearly to a single process on a single computer, to groups of clusters.

Among the SOA platforms, all in a tuxedo is a service that is accessible by name. A customer just calls a name service passing a buffer of information. Tuxedo automatically routes the request to the least loaded server that can handle the request, and then automatically dispatches the request to the server in the business logic associated with this service. The implementation of service then treats the query in the buffer and returns a buffer to the appellant that contains the response from the service. Requests are possible synchronous, asynchronous, queued, or one-way. Other services provided by Tuxedo include monitoring transactions to support distributed XA store transactions and messaging forwards with a variety of QoS options, pub/sub messaging, a variety of gateways to provide transparent access to MQ Series queue, the gateways, SNA and TCP to connect seamlessly to CICS and IMS applications and connectors Java that provide connectivity to the JEE application servers. Tuxedo services clients can be written in C, C++, COBOL, .net and Java.

With a complementary product called salt, Tuxedo can support bidirectional SOAP/HTTP (S) web services, allowing easy integration in other SOA environments. With salt, existing Tuxedo services can made available as services SOAP/HTTP (S) without modification on existing servers in Tuxedo. With respect to "package", salt the wrappers are used, or more precisely stubs and skeletons, in support of FCC standards. This allows the business logic implemented as a simple function of C++, Python, or Ruby and all messages and manipulation of the buffer is managed transparently by the generated salt stubs and skeletons. This can make it is quite easy to take a monolithic application and break into a set of services of Tuxedo with little or no changes to the existing monolithic application code.

Smoking also provides the ability, especially with the add-on TSAM (Tuxedo system) and Application Monitor which provides a followed detailed-to-end performance of a Tuxedo for surveillance and extensive management application.

Lately Tuxedo has been used by many customers to migrate their COBOL applications to environments inherited such as much cheaper IBM CICS and IMS on expensive mainframe to distributed systems. Two recent Tuxedo associated products and ART Workbench provide tooling and a delivery infrastructure to help him in these migrations, which are performed with only or mainly automated processing code that replaces mainframe specific APIs with Tuxedo compatible API. Business logic remains intact and only the API techniques are modified. These customers often find that their total cost of ownership of the migrated application is reduced by 50-80%, while maintaining the mainframe or better quality of service.

I hope that gives you an idea of what is Tuxedo. If you have any other questions, feel free to ask.

Kind regards

    Hello

    For question 12cR1 PeopleSoft and Tuxedo, you will need to check with the PeopleSoft team as I do not know their version dependencies.

    When you ask can coexist Tuxedo 10 and 12, the answer is Yes, although I don't know exactly what you mean by coexist.  They can be in the same field of MP, or in distinct areas linked through the gateway of the field.  If they are in the same domain, then the MASTER machine must be one who executes the later version of Tuxedo.

  • Q-Oracle/Tuxedo system alongside the version 6.0 or higher

    Hi Little Todd-Oracle how things are?

    My work team have two questions related to the queues in Oracle Tuxedo.

    our team wondered if Oracle Tuxedo/q system to 12.1.1.1 version can interoperate with Oracle Tuxedo/q system to version 6.0. We are in doubt if a Tuxedo domain to 12.1.1.1 version have access or a way to use the queues deployed in another area Tuxedo to version 6.00 or higher. If so? How does it work?

    Other questions are what concerns the advantages and disadvantages to have a queue by queue space or the queue of more than one in a single space in the queue? the reason why we ask, we realized that our client development environment and production environment are made slightly different. In the development environment, there is a space in the queue and the queues are in there but in the production environment has created a space of the queue for each queue.

    Could you provide some ideas of theses and expertise for us?

    Thank you so much once again.

    We hope that you do well.

    Best regards.

    Hello

    I'm fine, thanks for asking!

    About the interoperability/q, I know exactly what you are trying to accomplish.  If it is really several areas, then it should not be a problem.  / Q use the servers TMQUEUE access to the queues/q.  These TMQUEUE servers are accessed through a service name that is the same as the name of queue/q.  He tpenqueue() and tpdequeue() API just call a service under the name of the queue under the covers.  If you can bear/q on several areas important name space of expectation as a service name in the configuration of the domain gateway.  We support connections between the different versions of Tuxedo, it "should" work, which means that the customer or you need to test this first.  Make sense?

    Regarding the queues by queue space, I think it is largely a question of scalability.  Each queue has one or more servers TMQUEUE who manages the space in the queue including all queues.  So if you have a single space with 5 cocks in it and a single server TMQUEUE queue, you can manage maximum simultaneous operations for queues 1/q.  You had defined the 5 lines each in a separate queue space, then each would have its own server TMQUEUE which means you could service 5/waiting queue of requests simultaneously.

    I hope that helps!

  • Tuxedo of Oracle and Oracle Tuxedo message queue on a virtual machine.

    Hi friends.

    How is it going?

    A small question.

    So let's go live using Oracle Tuxedo 12.1.1.0 with binding distinguished Bulletin Board and Oracle Tuxedo Message Queue 12.1.1.0 on a Virtual Machine (VMWARE) running Oracle Linux 6.2. However, we want to know if there are recommendations or mishaps in which we face before running Oracle Tuxedo on a virtual machine?

    I mean, I wonder if I have to worry about kernel parameters, settings of virtual machine or any other thing that could ruin everything.

    Another question.

    Oracle also provides certification of VMS where Tuxedo Oracle would go on top of the?

    Todd little-Oracle

    Maurice G-Oracle

    Hi Bruno.

    I'm not sure what you mean with single Liaison Bulletin Board.  I guess you mean a cluster or the MP configuration?  And is it really a clustered or just a single machine of the MP configuration?

    About the configuration, you use Tuxedo services as well or just Tuxedo Message Queue?  The biggest problem with the configuration of the BONE is the IPC resources.  If you do a-c tmloadcf on your UBBCONFIG file, it will help you to determine the required minimum IPC resources.  In general, I suggest configuration much more resources than the minimum to allow for the changes to come and for some of the parameters for heavier loads.  In particular IPC message queue settings are strongly dependent on the load.  So make sure that the maximum message size and the size of the queue are big enough for your expected workload.  You can monitor the slot load using the ipcs command.

    We don't certify virtual machine environment, but support also a long time the VM vendor to ensure compatibility, obviously VMware and Oracle VM who both do.

  • What exactly does the Time Machine backup?

    What exactly does the Time Machine backup?

    We have a Mac Pro towers (NOT for sale) and Mac mini with several hard drives installed internally.   Time Machine backup all internal disks or just the boot disk?   This can be configured?

    Time Machine backs up your default boot partition. However, if you have more than one drive or partition on your Mac (and it is formatted in "Mac OS extended (journaled)"), you can set the Time Machine to save these drives too. You can do this by removing these drives from the list of excluded items in System-> Time Machine-> Options... Preferences, so that the next backup will include all internal hard drives or partitions that you want to back up too.

  • What exactly does the "recovery disk"?

    I'm about to reinstall everything on my laptop but would like to know what exactly is the "recovery disk"...

    I presume that it formats the HARD drive with a clean installation of the operating system and all applications toshiba as a CD burner, VAP etc. are NOT installed and must be installed afterwards?

    Well, the restore CD contains an image of Toshiba. Toshiba picture is a package and contains a Windows operating system, the Toshiba drivers, tools and additional software.
    Simply said that it contains everything that you might find preinstalled on the Toshiba laptop.

    And Yes; the recovery CD formats the drive HARD integer (also partitions) and install everything again.
    It redefines the laptop to factory settings

  • The FX - 670 k, what exactly?

    I know that it is mainly a forum for peer-to-peer, but there are some officials in HP lurking around here, so I might as well ask the question:

    What exactly is the difference between the AMD FX - 670 k and an ordinary AMD A10-6700 APU? They have the same exact basic features. Is it simply that the FX - 670 k is unlocked (via the 'k' suffix)? It is even at all unlocked?

    Or it is just an attempt between HP and AMD to obfuscation to make an APU with a processor rather weak power seem more respectable in desktop systems? Because that's what I think, and I would be happy to be refuted that large companies are that cynical.

    Hello Zacabeb,

    The difference between the two is that with the AMD FX - 670 k has removed the HD D 8670.
    You can read a bit more on the difference through the following article

  • What exactly happens when you change the name of the computer, and it asks you to restart?

    What exactly happens when you change the name of the computer, and it asks you to restart - relating to the registration and identification of network?  Specifically when a computer isn't yet in one area but is still in a working group.  Y at - it show any PC by informing other computers it's name has changed?

    Computers into working groups are actively seeking each other, so if you rename a computer, it will not be shown anything. The restart is to erase the name of origin since the system cache, he will think that it's always the old name until the reboot takes place. Work computers is simply 'shake hands' with each other whenever they need to communicate.

    Computers that are part of a domain are created a 'computer' account that is assigned a random password that changes every 30 days by default automatically. These computer accounts work almost identical to an Active Directory user account, which means that they are not proactive they simply cached credentials with their permissions to provide if / when requested by heritage in the environment.
    Users and computers Active Directory accounts are stored in the NTDS. SAID the database, the backbone of an AD environment. When a computer name changes in one area, it takes the PC restarted simply for the PC. The change of name in Active Directory will replicate throughout the environment based on the settings of replication of this environment.
    I'm too simplify all this, but the general concept is there.
  • What exactly should I have?

    Although I'm an addict of the Acer, I just joined the community because I can't find the answer to my question.  I recently bought a Ultrabook through my Government company that had this description of a ultrabook that I intend to get.

    Acer Aspire S7 13.3 in. display 4 GB memory Ultrabook AS2500S1

    • Operating system: Windows 8
    • Processor & memory: I5-3317U processor Intel (1.7 GHz) 2.6 GHz dual-core with Turbo Boost technology; 4 GB memory
    • Storage: 128 GB Solid State Drive
    • Display & Design: 13.3 "CineCrystal HD LED backlit; resolution 1366 x 768; Black finish; Measure 12.8 "W x 8.9" D; 2.65 lbs.
    • Video/graphic: Graphics Intel HD 4000
    • Audio speakers: Built-in speakers
    • Includes: Built-in webcam and Microphone; Multi-Geste
    • Battery & connectivity: Up to 6.5 hours portable; WiFi; Bluetooth 4.0
    • I/o ports: HDMI 1; 2 USB 3.0 Ports; Intel certified card reader Thunderbolt
    • Approved ENERGY STAR: Yes

    When I arrived at the unit, he seemed to make the one I ordered, the box showed Aspire S5.  Then I searched this site for and S5 and it will not end.  I tried the AS2500S1 part number and unity, he showed was a V5 with features completely different and sold in another country.  When I search the SKU # 2312983, a mobile phone watch bundle.  Can someone say please 1) what exactly should I? (2) if there are, the S5 is cheaper than what I order?  (3) is there a difference?  Thanks in advance.

    Is what color? I think what the S7 comes color is white and the S5 is black. The S7 is the supermodel for acer. It features a 1920 x 1080 p screen, while the S5 has a 1366 x 768 p display. Also, I don't think that the S5 is a touch screen.

  • What EXACTLY should I submit?

    Hmm, a basic question, but I cannot find an answer anywhere -

    When I compile my application with Blackberry JDK, it spits out 3 files: 1 COD (which is in fact a zip of several small COD), JAD 1, 1 JAR.

    Now, what EXACTLY should I submit to App World?

    -the only cod, or

    -the COD and JAD (both of which are compressed in a zip archive?) or

    -cod, JAD and JAR?

    No, you don't need the JAD for App World. But it won't hurt if you include it.

    Simply put, you need not to worry.

    The JAD files are used for OTA downloads (download the application via the browser). You will need to provide this if you download your application to sites like Mobihand, App World does not use OTA, so it is not necessary.

    The JAR file is not necessary for anything. I don't know yet why the compiler produces.

  • BlackBerry smartphones, what exactly is Standby mode?

    In a quest to figure out how to activate the stop screen when I want to, I found the sleep mode, what exactly does.  All the manual says about it is to press mute to switch to standby mode, but does not say anything on this subject.  "Sleep mode", what exactly?  He always give me alerts calendar and phone calls and other alerts, or is he basically disabled?

    Jesse

    The standby mode is just a low power state to conserve battery power. He closed the backlight and screen and does not meet the presses until do you wake. Your notifications, phone calls, etc. are not affected by it.

    The case serves the same purpose: it has a magnet that is detected by the phone to put it to sleep. If you go to the notification / ringtone profile settings, you will notice 2 different setting: off the case and in the case.
