• Question on how to deploy Oracle Tuxedo JCA adapter

  Hi all:
  I have question on how to deploy the JCA Tuxedo Oracle Weblogic 11g adapter (10.3.3).
  I try to deploy a jar file. But the web application cannot find the JNDI name that defined in the JCA Tuxedo adapter.
  Then I tried to deploy it as a web application. The console can be found this way JNDI name.
  
  However, there was a FAILED Module Exception:
  
  weblogic.application.ModuleException: java.lang.NullPointerException
  at weblogic.connector.deploy.ConnectorModule.prepare(ConnectorModule.java:239)
  Caused by: java.lang.NullPointerException
  at weblogic.connector.external.impl.RAComplianceChecker.hasMatchingConnFactoryInterfaceInRA(RAComplianceChecker.java:668)
  
  Could someone help me on this issue?
  
  Thanks for any information!

  Dawn,

  You must use the RAR file. (a file with the extension 'rar' and created using the jar) When you have downloaded Tuxedo of OTN JCA adapter you have is a RAR file.

  After downloading the RAR file to your local workstation, you need to configure, reconditioning and then you can deploy them.

  Use the following to set up procedure and reconditioning
  1 create a sub-diretory called 'adapts' r in the directory where you downloaded the file com.oracle.tuxedo.TuxedoAdapter.rar
  2 cd of ' adapter
  3 unjar the RAR file
  adapter > jar xvf... /com. Oracle.Tuxedo.TuxedoAdapter.rar
  4. to set up
  1. the downloaded file com.oracle.tuxedo.TuxedoAdapter.rar UN - jar
  2. change the configuration
  2.1 if you wish to use the connection configuration factory founded, then change the META-INF/weblogic - RA.Xml
  2.2 If you want to use the domain configuration file, then change the META-INF/ra.xml and then change dmconfig.xml
  NOTE 1: factory based configuration only supported in 11.1.1.2.1
  NOTE 2: the JNDI name is in META-INF/weblogic - RA.xml and you can change to the JNDI name that you like
  5 renovation
  adapter >... jar cvf MyTuxedoAdapter.rar *.

  Now you are ready to deploy JCA Tuxedo adapter
  There are two ways to deploy it to WLS
  1 use the console to configure it as an application
  NOTE: This is the only way that support the main map. Main mapping configuration is necessary for the propagation of security identity of Tuxedo for access control. (you also need to have a copy in the file of Tuxedo TPUSR locally and configured in the configuration)
  2 copy the RAR file into DOMAIN_HOME/autodeploy directory $

  NOTE: you must replace the JATMI that come with WLS and use the one that come with adapter JCA Tuxedo.

  You can also download the sample of RTO and run the example and check the information listed in the file readme.txt and build.xml ANT script and setenv.sh you can find all the information mentioned above.

• 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

  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.

• 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!

• R2 Oracle Tuxedo

  Hi people.

  My name is Bruno Taboada I found here to ask some questions.

  I am creating a sample project using Oracle Tuxedo Release 2, however, I have some question about it.

  First, I created a simple project to a queue and waiting and that it worked fine, but when I tried to test some examples of oracle documentation I realized the new version of oracle Tuxedo does contain some features such as: tpenqplus() but tpenqueue() one definition. So, with this in mind, I wonder if the 12cR2 Oracle Tuxedo (12.1.3) there is a queue of messages from Tuxedo Oracle? in the opposite case.

  How to install Oracle Tuxedo Message Queue (12.1.1.0) in 12cR2 Oracle Tuxedo (12.1.3)? or else

  Should I use Oracle Tuxedo 12cR1 (12.1.1.0) because it's already been perfectly integrated to other modules of Tuxedo oracle like salt, TSAM including OTMQ?

  Fact 12cR2 Oracle Tuxedo (12.1.3) along Oracle Tuxedo Message Queue (12.1.1.0) separately but taking part in the same area? in this case, it is recommended to be deployed as such? How does it work? I have no idea. any suspicion?

  Finally, Oracle goes to get out a built-in version of Oracle Tuxedo (12.1.3) 12cR2 with Oracle Tuxedo Message Queue? in the affirmative. When will it be?

  I hope that I was clear enough.

  Thanks in advance for all replies.

  Best regards.

  Todd little-Oracle

  Hi Bruno.

  Queue messages from Tuxedo is a product of queues advanced messages that combines reliability and transactional features of the Tuxedo/q with the rich capabilities of Oracle MessageQ of e-mail.  So, the answer is simple if/q will meet your needs in a Tuxedo application, use/q.  If you don't need all the features of tuxedo, but you need robust advanced messaging, use messages from Tuxedo queue.  If you need both, add Tuxedo queue of messages on Tuxedo.  So if you need things like notification of delivery, offline messaging, and other more advanced messaging facilities Tuxedo/q provides and if you still need a Tuxedo, add Tuxedo messages on Tuxedo queue.

  Kind regards

• 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,
  Rahul.R.Buddala

  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

• Install HRCS9.0 Linux question: the application designer and Tuxedo domain Boot have SQL error

  People,

  
  Hello. I was installing HCM and Campus Solution 9.0 with PeopleTools8.53. Server machine is Oracle Linux 5.10 and Windows XP-based client computer.  The architecture of my internet is WebLogic11g/Tuxedo11g/OracleDatabase 11 GR 1 material. PeopleTools 8,53 works correctly in the browser.

  In the database server Oracle Linux 5.10 machine, I run scripts 'createdb10.sql, utlspace.sql, hrcddl.sql, dbowner.sql, psroles.sql, psadmin.sql and connect.sql' one by one. Can I use Data Mover to load Windows XP data into the Oracle Linux 5.10 DB HRCS90 instance. The Data Mover script hrcs90ora.dms is done correctly in Windows XP. Configuration Manager is configured correctly.  But when I login in the application designer, I can't connect and get the message as below:

  
  «Security Table Manager (Get): the database is release 8.52.»  The PeopleTools running require databases at 8.53 release. »

  
  I followed the http://docs.oracle.com/cd/E37306_02/psft/acrobat/PeopleTools-8.53-Upgrade_02-2013.pdf document to upgrade HCM and HR 9.0 revision 5 Database Instance HRCS90 in Oracle Database Server with Linux. My upgrade is complete. The above problem is solved.

  When I login in the application designer in Windows XP, the error message as below:

  I checked the PSOPRDEFN table in the database Linux HRCS90, not the OPERPSWDSALT field.

  I also checked the connection process PS the user traverses the 3 tables: PSOPRDEFN and PSACCESSPRFL, PSSTATUS.

  My oprid, the symbolicid and the accessid ownerid in the 3 tables are correct.

  My question is:

  Why is there a strange OPERPSWDSALT field in the SQL statement that causes Signon failed?  How to solve the problem of access code?

  Thank you.

  > Then it connects with SQL > and then run script rel853.sql, but its outcome is not just because the database is started with sysdba.

  The database is always started '' as sysdba. '' "Useless" to connect as sysdba to run the PSoft script while accessid.

  You need to come back in the book of the Oracle.

  Fair enough, this is my last word to this thread.

• Oracle 11g compatibility with oracle 10g and 9i?

  
  Hi all
  
  
  
  I have a few questions about the compatibility of 11g.
  
  
  
  Client Oracle 11g is compatible with oracle 10g client that is already installed on the desktop computer?
  
  
  If any changes to do so and where?
  
  
  
  Is oracle 11g oracle 10 g/9i on the same server where are installed the 10 g/9i compatible?
  
  
  Concerning
  
  

  If the question you ask yourself is 'Can I have multiple versions of the Oracle installed on the same client computer' or "Can I have several versions of the database Oracle installed on the same machine", the answer is Yes. As long as you install each version in another House of Oracle, and we are talking about versions 8.1.5 and upward, you can have as many different versions of the client and the database on the same machine as you wish. Of course, you are still subject to the support of operating system compatibility (e.g. Oracle 9.2 did not had been supported on Windows 2008, so do not expect to work).

  The only problem you may have would be with components that are not compatible with several House. This mainly affects third-party Windows drivers (drivers third party ODBC, etc.) who do not know how to work with multiple Oracle homes and end up using which version of the client Oracle happens to appear first in the path.

• DesignJet T1100ps: Question of compatibility T1100mfp

  Hello.

  My company is owner of scanner and plotter connected together via a USB cable. The two devices are connected to our network separately. Scanner is DesignJet T1100mfp and DesignJet T1100PS plotter.

  In the near future we would like to replace our current plotter with the newest one, but we would like to continue to use our current scanner (with regulator).

  We contacted the official HP service center for our country and their response was that they do not know the answer and it is should be tested first. Now for us to test it, we would have to buy the new tracer first, then test it, which is obviously not an option.

  So my question is can where to find list of supported for this scanner devices so that we could get the best ratio price/performance ration about compatibility?  DesigjJet T1300 is compatible with this particular scanner. Or can anyone suggest the best solution.

  Thanks in advance

  Hello

  You can connect the T1300 on a T1100 scanner.

  You need to update the software of your scanner first.

  Here is the link to get the software

• Stupid question about compatibility

  I would be happy to search the forum for inDesign to discssions on compatibility with other editions, but it seems that it is impossible. Where this stupid question.

  Problem: a uniform translation ends me back-saved files in InDesign CS, which I created originally, but I can't open them.

  This that I have to spend $500 on an upgrade so I can open it or is there a way they can back - save it so I can open it?

  Thank you

  I think that I get it now. I doubt that the files have been saved as files InDesign CS. As I said before, it is impossible to back - save as InDesign files. Only InDesign X can save to a file, InDesign X. very probably, the provider is you open files in a later version of InDesign and save as native file of this version, InDesign 4, 5 or 6, you cannot open.

  You have three options:

  1. You are upgrading InDesign to be compatible with the version of the provider.
  2. Only translated text files, then you replace the text in your files.
  3. Having the export INX since InDesign 4 provider. If they use later to edit it can be a loss of hassle and risks of formatting.

• Question RE: being an Oracle Developer, best practices.

  Dear Oracle gurus:
  
  If you would be so kind as to entertain a few lame need questions will Jr. Oracle Developer, I would be very happy!
  
  1. If I understand correctly, I can pretty much Learn SQL and PL/SQL using Oracle 10 g Express without the need to install further configuration of Oracle? SQL Developer and Oracle 10 g Express would be sufficient for learning SQL and PL/SQL?
  
  2. how the future for an Oracle developer who is well versed in SQL and PL/SQL? Was hoping to specialize in this aspect of Oracle and may continue with the discoverer (I had previously had some experience deploy reports in Discoverer 3/3i). Your opinions?
  
  3. as an Oracle Developer, am I supposed to know that s/n matter as well? Or stick to the development? The reason why I ask is - I found that if I try to do too much, a whole bunch of nothing does happen. Isn't better to focus on something and do it well?
  
  4. any ideas or comments about the future of development in Oracle you want to share?
  
  Thank you for your time! :)

  Oracle 10g Express Edition will give you at least 1 year of learning. If you are really able to SQL and PL/SQL Express, you are longer than many so-called Oracle professionals.

  2. how the future for an Oracle developer who is well versed in SQL and PL/SQL? Was hoping to specialize in this aspect of Oracle and may continue with the discoverer (I had previously had some experience deploy reports in Discoverer 3/3i). Your opinions?

  Unfortunately, I see that SQL and PL/SQL to be lost in the hype Java and .net. More and more developers and applications forget the basics of database.

  Indeed, a much touted merger devleopment demo focuses strongly on tanks (single general-purpose attribute-value lookup Table)

  3. as an Oracle Developer, am I supposed to know that s/n matter as well? Or stick to the development? The reason why I ask is - I found that if I try to do too much, a whole bunch of nothing does happen. Isn't better to focus on something and do it well?

  A good developer knows his tool. A good database developer Oracle SQL doesn't understand.

  A great developer Oracle includes the internal implications of the database, but also a DBA. Both (but rarely) should work closely together.

  For example, a great developer understands that you do not commit in a loop. The 'why' of it is often seen by developers as "something DBA.

  4. any ideas or comments about the future of development in Oracle you want to share?

  I would say a lot of reading is in front of you. I would encourage the following, in the following order:

  Manual chapter, Oracle Concepts 1
  Guide the developer Oracle - foundations, chapters 1 & 2
  one of the books of database Oracle Expert Tom Kyte
  O'Reilly books "SQL Cookbook"
  Books O'Reilly Oracle PL/SQL (co-) written by Steve Feuerstein
  ORacle concepts, the rest
  Dan Morgan Library to http://www.morganslibrary.com
  Developer's Guide - Fundamentals - Oracle the rest
  The Oracle - other as interest falls Developer's Guide

  Oracle guides are available from http://tahiti.oracle.com and most SQL and PL/SQL can be exercised on the free and moderately light (sic) Express Edition.
