• A single Instance of a RT signal capture

  Hello

  I looked through and through for a simple way to capture a single instance of an analog input signal and store it as a constant. To be more precise, I want to take the first value that an analog signal is broadcast during the program execution and stores it as a constant to be used elsewhere.

  Thanks for any help the community forum might be able to provide.

  Hi Doug,.

  Look at this article on functional global variables. You can use this model to define the value once and then read it in the world within your application.

• file extension association to open only a single instance

  Hello

  I see this question posted in several forums on the internet, but I'm not able to find a definitive and functional solution. Here's the problem:

  When I do a combination of file extension to my request, if I select more than one file and then select open from the context menu, I get multiple instances of my application, one for each selected file.

  The same commenting on my application, I already put code to limit the app to run a single instance. Normally works, however, by selecting several files and then by selecting the command open, it seems that the code that check whether a previous instance is running realized too late, the system starts already several open orders.

  Is there a way to tell Windows to open the list of files selected in an instance unique app? If so, how.

  Thank you.

  Without more details on the specifics of your application, it is difficult to suggest a specific development forum.  I suggest you choose one from here: http://social.msdn.microsoft.com/Forums/en-US/categories

• How to implement a stack of screen "single instance".

  I'm looking to implement an application that accepts only a single instance of specific screens.  What is the best way to achieve this?  I have checked the documentation and can't seem to find anything that addresses this issue.

  The idea is similar to a singleton pattern...

  If (screen is nothing)

  {

  screen = new XYZScreen ();

  }

  return to display;

  If I already pushed my XYZScreen in the stack, using the pushScreen() method, I would like to get a handle to that instance, and they have to protest against the creation of another instance and add it also.  Also the memory problem, it makes more sense for the particular project that we are working on.

  I can't seem to find anything like "UiApplication.getUiApplication.getScreen ()" to get a reference to a particular screen already on the stack, or a 'Stack.moveScreenToTop () '.

  Suggestions, examples or links would be appreciated.

  You can use getActiveScreen() and getScreenBelow() in a loop to see if your display is already present in the stack to display.  If this is the case, then pop, and you then press it to remove it from its current position and make it visible.  If it is not on the stack, you can just push it.

  It works for you?

• Primary database is RAC and physical intelligence is the single instance

  Hi all
  
  I use Oracle RAC 11.2.0.3 as primary database, we will begin to use the Oracle Data Guard.
  I am designing my infrastructure and planing to use single instance Oracle 11.2.0.3 my stand physical database.
  
  My question is it possible to have my sleep as single instance database while the primary is RAC?
  is it possible to build my Oracle database single instance ensures from the primary database to the RAC, RMAN backup?
  Are there restrictions (or all of the points to consider) as my primary database is CARS while the physics of Eve is the only Oracle instance?
  
  in the link below
  [http://docs.oracle.com/cd/B28359_01/server.111/b28294/concepts.htm#i1039416]
  It was mentioned that primary can be CARS or simple and even the day before, but my question is possible to have primary as CARS all on standby as single instance? or it should be like each other?
  

  The primary database can be either a single-instance Oracle database or an Oracle Real Application Clusters (RAC) database.
  Similar to a primary database, a standby database can be either a single-instance Oracle database or an Oracle RAC database.

  Kind regards

• How to "turn on" an ABC agent single instance/Server?

  As a result of this thread: How to create an instance of "Agent ABC" only?
  
  I had many problems of implementation of the instance of 'EAC only Agent', as you can see in the previous discussions. I had all this work, but I guess I didn't understand what I ended up doing.
  
  The instance was restarted or recycled as part of an upgrade and now the dgraph process does not start. In fact, I don't know how to start it. I assumed, he launched the instance of control station/CEC. The EAC does not seem to run on the only case of an agent, so there is no way for all orders get sent to the EAC.
  
  I was working with the assumption that the only case of agent didn't need all the configurations. And I have never been documented manually start EAC on this single instance of agent.
  
  Am I guess just to start PlatformServices / EAC with the same command I use on the Server central/command of EAC?
  "cd $HOME/endeca/PlatformServices/6.1.3/tools/server/bin".
  ' nohup endeca_run.sh & '.

  In version 6.1.2 Platform service, you start with:

  source /home/gose/endeca/MDEX/6.2.2/mdex_setup_sh.ini
  source /home/gose/endeca/PlatformServices/workspace/setup/installer_sh.ini
  $ENDECA_ROOT/tools/server/bin/startup.sh

  Services Platform will work as a controller of ABC Application if there is the following file:

  $ENDECA_CONF/conf/Standalone/localhost/eac.xml

  If you delete this file (or if it does not exist), the installation will run as an Agent of the CAE.

• can we use Grid Infrastructure 11.2 to protect a single instance database?

  Hi all
  
  I would use Oracle Grid Infrastructure to protect a single instance database.
  I found these documents:
  http://www.Oracle.com/technetwork/products/Clusterware/overview/em-DB-failover-128585.PDF (for 10.2)
  http://www.Oracle.com/technetwork/products/Clusterware/overview/SI-DB-failover-11g-134623.PDF (by 11.1)
  
  I was unable to find a similar document for 11.2 GI. Do you know if such a document exists?
  
  At the moment I only know that the IM is free if used for Oracle products, but I'm not shure if it can be used for external applications one-time protext or databases
  
  Andrea

  Hello

  While it is still working (failover scripts you find in the demo folder $GI_HOME7/src/demo/coldfailover), the document does not exist, because with 11 GR 2, there is a solution to support called RAC ONE node, so make the manual configuration of obsolete.

• Start several Instances of ABC to a single Instance of the EBS provider

  Dears
  
  Currently an initiative of integration, we are integrating next design flow:
  
  (1) we have a single applicant request; We design the related ABC applicant
  (2) we use on single EBS. We use the EBS synchronization operation
  (3) we have 2 provider ABC
  
  Our business requirement is:
  If a single message is derived from the application of the applicant by the applicant, ABC, it must be published both applications via ABC provider provider components. In fact an instance of ABC single applicant will create, only one instance of the EBS and 2 provider ABC instance created
  
  Can you please suggest how we can design the EBS service in such a way that 2 instances of provider ABC will be created from single instance of EBS
  
  Thanks in advance
  
  Best regards

  The answer to your question is Yes, one Ombudsman can invoke two service calls at the same time as well.
  First of all, define your service references in the composite.xml
  Once you have done this, you can add any number of routing rules for each operation defined in the Ombudsman. In your case, you need to add two static routing rules within the same operation in the Ombudsman file. You can also select if the calls will be sequential or parallel by selecting the correct value in the drop down within the routing rule. Each routing rule will call a service reference in your case.

• Names of single instance in distributed environment

  The 11.1.2.1 installation guide (http://download.oracle.com/docs/cd/E17236_01/epm.1112/epm_install_11121.pdf) says on page 122 of the .pdf:
  
  + "When the configuration in a distributed environment, you provide a name of the new single instance that you configure each server. For example, if you use the epmsystem1 of name of default instance on the first server, and you keep the same names on the Server naming convention, create you new instance names unique on each subsequent server, like epmsystem2, epmsystem3 and so on. » +
  
  No reason not to follow this opinion, but I was wondering if it is really necessary. I'm sure I've seen facilities where "epmsystem1" has been used for for example a web application server and the Essbase server. Perhaps, I was remembering incorrectly.

  Yes, each server requires a unique name as it is registered the server with the register of SSP against the instance name, maybe it was on a 11.1.2.0 deployment that you saw the same instance name in the distributed environment.

  See you soon

• DEV and quality assurance within the oracle single instance

  We have our DEV and QA in a single instance of oracle. Scripts that refer to table in DEV names will be copied on to QA DEV quality assurance tests for unit tests at the end. DEV, extract us data from 5 source systems, one for each State of the United States, which use the same application, so the names of the source tables are identical, and so in our staging area we have a scheme by the State such as TX, GA, MD and we extract data in tables that are identical to the staging tables. As cross us the aggregation state our scripts should refer to TX.employee and GA.employee in the same sql statement.
  
  What is the best design for this using SCHEMAS, DATABASES VIRTUAL PRIVATE, VIEWS, SYNONYMS etc.?
  
  
  
  
  
  Thank you in anticipation

  Just for my knowledge, if I found myself in this situation of VIRTUAL PRIVATE databases would make sense here?

  I guess that you could possibly use VPD. But it would create major problems if you have always wanted to make schema changes - you could not add a new column to a table in DEV, for example, without this column is also available in AQ. You could not have code in DEV that does not exist in QA. I guess you could really get fancy and use g 11 edition redefinition to have an edition of dev and qa edition but I wouldn't think how to promote prod code in this kind of environment. In addition, editions is a characteristic of the company (at least, I'm not sure if it is an extra cost option) which would tend to be beyond the solvency of the company trying to save on licensing costs by combining dev & qa in a single server non - VM (and even less in the same instance).

  You may have your application use any dynamic SQL so that dev could use the DEV_TX while QA scheme used the QA_TEX schema and it was only the schema of TX in prod, but that obviously never gets old very quickly. You can create a single set of synonyms the synonym TX_FOO points to DEV_TX. FOO for users of dev and TEST_TX. FOO for test users, but then you will have to remove qualifiers to schema of all your SQL queries.

  In short, an application like you describe trying to share an instance would be a pretty massive undertaking.

• Upgrade or install fresh to 11g RAC 10 GB Single Instance base data?

  What are the benefits of taking a server Oracle 10 g clone and carry it to the node two ORACLE RAC?
  
  I think I could do the following:
  1. install and configure Oracle Clusterware
  2. install and configure the software database only
  3. get a database of clone of 10 g (database file, init.ora, trace controlfile.
  4. apply the database 10 g of Clone on the Oracle RAC 11 g database waiting it to be accessible from both nodes
  
  
  The other Option
  1. install the Oracle 10 g database software in the new environment
  2. get a clone of 10 g production database and apply to the new development environment
  3. install the software of database 11 g only
  4. turn to level 10 g single instance of database 11 g single instance
  5. install and configure the cluster 11 g clusterware
  6 move the single instance of 11 g to 11 g RAC
  
  
  When it is maybe a good idea to add DSO for this implementation? Your ideas are appreciated.
  
  Thanks in advance!

  Hello
  If you have 3 business applications, so it is good to have 3 diff for all 3 applications services it will however help only if you have multi RAC node where you have the flexibility to define the services running on specific nodes so now two node RAC, it will not be very different.

  That your goal is both fault-tolerance, I suggest you create a service with a favorite and one available to get load balancing server side, select also load_balance = yes and failover_on on the entry of TNS to switch client-side client-side.

  I hope you know for failover, only queries select are get toggled if method = select. DML is not supported for failover and you have to manage with DML failover demand only.

  Please check my blog for more details on the RAC load balancing, failover and services below.

  Thanks in advance.

  Hello

  Haven't you designate all these documents, only to those that are applicable.

  For RAC to cloning no CARS, please see (Note: 783188,1 - certified CARS for the E-Business Suite cloning scenarios). If you don't have a CAR on the source/target nodes, you don't need this document.

  There is something more that you can refer to see (R12 Data Guard with database 11g)--(Note: 1070033.1-Business Continuity for Oracle E-Business communiqué 12 utilisant Oracle 11g Physical Standby Database) for more details.

• convert CARS to single instance ebs R12

  Hi all
  
  I couldn't find any docs on metalink about converting R12 EBS of a RAC (2 nodes) to a single instance.
  If you know all the note please let know me.
  
  Thanks in advance.

  Hello

  Note: 406982.1 - cloning Oracle Applications V12 with quick Clone and
  Note: 559518.1 - cloning Oracle E-Business Suite Release 12 RAC systems compatible with the Rapid Clone

  can you tell that one to CARS to single instance using filesystem cook. ?

  As already said, there is no specific notes covering the cloning of the CARS with no CARS. Use the old note to clone non RAC with no CARS and the second to clone of CARS at the RAC.

• Single Instance Oracle 11.2.0.4.7 with GRID + ASM - AMT headphone attack Poison Fix?

  I'm under a single Instance Oracle 11.2.0.4.7 with GRID + ASM database on Red Hat Enterprise Linux 5.7. I'm trying to fix the infamous TNS Listener Poison attack vulnerability. I tried to implement the COST using this guide (Doc ID 1453883.1) but it doesn't seem to work as it still appears on a scan of the retina. I can't get a remote listener to register to test the vulnerability, and it does not appear in the log listener xml as a registration or denied. Don't know what I'm doing wrong.

  
  

  I added this to my listener.ora:

  SECURE_REGISTER_LISTENER_PROD = (CPI, TCP)

  The Alternative fix to the COST must turn off dynamic registration but I can do it when executing grid with the DSO with only a single instance database?

  How can I fix with my setup?

  You would implement better VNCR on 11.2.0.4:

  for CARS: 1914282.1

  the properties of a single instance: 1600630.1
