• DB Oracle 11 g r2 Configuration process and the session

  I recently installed DB Oracle 11g R2 and 50,000 users connect to this database suggest me what would be the basic configurations.
  Sessions settings and database processes are 5000 and 5505 but it is lagging bit now so if its possible I want to make maximum processes and sessions or automatic.

  And the platform would be?
  Windows is not suitable for this number of users.
  And even on Unix, I would if I were you configure shared server or connection pooling.

• I want to know that the total number allowed per process and overall user objects?

  In my system, I have windows xp sp3 installed. my system by the number of user process object is 10000. When the total user of my system object reaches 10000, I'll be able to do whatever it is like opening a new tab in iexplorer. so, I just want to be consistent with what is the total number by process and in the entire system (all processes)

  Please read the documentation of the requirement for Oracle APEX 5. Ensure that your environment meets these requirements. Upgrade your oracle database or other software if necessary components and then you can go right 4.1/4.2 to 5.0 update according to the above-discussed upgrade strategies in the above discussions.

  Reference: https://docs.oracle.com/cd/E59726_01/install.50/e39144/pre_require.htm#HTMIG376

  You should go for upgrade of the Oracle APEX of 4.1 to 5.x. Regression test your applications to remove if any errors introduced by upgrade. The kickoff of a new project to migrate your applications to universal theme.

• Layers of combine: logic, process and Apex pages gui?

  When explaining models for example relational data or logic model, it is often easier if the template could be included as well as the process, or to the Applications Page navigation?

  Is it possible to combine the photo layer designs?

  How to represent on the elements of unique scheme of mode of data flow diagrams and logical and relational data types is shown here http://www.thatjeffsmith.com/archive/2015/04/more-fun-with-data-modeler-diagrams-in-version-4-1/

  So that I could begin to show the first process then add navigation of gui beside him and turn more details to the display by clicking the layer 'SHOW '.

  You can create overview subview as entry point to the network of the subviews nested - you can navigate forward and back using "Figure" diagram nested and ' go to the diagram >... ". "feature

• How to plan the propagation process and/or application

  Hi all
  
  Is it possible to predict the spread and application during the Oracle Streams configuration?, I mean, I don't want to run replication online because I have other object outside the Oracle who need to reproduce within the db to get my aplication (red only) in sync.
  
  So, when I can do? Here is an example of process apply and spread:
  
  BEGIN
  DBMS_STREAMS_ADM. () ADD_SCHEMA_RULES
  schema_name = > 'shm '.
  streams_type = > 'apply ',.
  streams_name = > 'apply_from_db1 ',.
  queue_name = > "strmadmin.from_db1"
  include_dml = > true,
  include_ddl = > true,
  source_database = > "db1.world"
  inclusion_rule = > true);
  END;
  /
  
  .....
  
  BEGIN
  DBMS_STREAMS_ADM. () ADD_SCHEMA_PROPAGATION_RULES
  schema_name = > 'shm '.
  streams_name = > 'db1_to_db2 ',.
  source_queue_name = > 'strmadmin.captured_db1 ',.
  destination_queue_name = > '[email protected] ',.
  include_dml = > true,
  include_ddl = > true,
  source_database = > "db1.world"
  inclusion_rule = > true,
  queue_to_queue = > true);
  END;
  /
  
  Perhaps, am I is not clear to my question, or maybe I do everything in the bad sense on propagation processes and the workflow application.
  
  So, I looked in all the documents available and I can't find how to plan the process... What is the part that I am missundertanding?
  
  As long I have it other non Oracle objects (system files objects, we say that some objects in ECM file system related with data) to replicate with the data schema, I can't replicate any changes to the schema of the source table to the schema database of fate (automatically). So, I'm replicated ECM file systems objects in other external tool (with build-in Windows Calendar integration)... but how I can program spread and/or application treats in the middle of stream 2-way?
  
  Please, I need a hint of someone as soon as possible.
  
  Thanks in advance.

  Your question is not very clear, so here's what you need to know abot schedules DBMS_STREAMS_ADM and spread:

  The schedule is done automatically when you add the spread with DBMS_STREAMS_ADM.
  This API DBMS_STREAMS_ADM encompass several other APIs:

  -DBMS_CAPTURE_ADM,
  -DBMS_RULE_ADM
  -DBMS_APPLY_ADM
  -DBMS_PROPAGATION_ADM.
  -DBMS_AQ_ADM

  This DBMS_STREAMS_ADM is supposed to make things easier, but it takes an important definition default values, so that you see all the actions that are performed as they are done quietly behind the scenes.
  The establishment of the regular spread is on of these silent setting and the time that occurs with a never ending cycle to wake up/run/sleep.
  The duration of sleep between 2 execution is defined by DBA_QUEUE_SCHEDULES. LATENCY

  From the spread itself, it's a job. When the next execution is set to null, he reschedule itself, like an endless loop.
  Here's how the job will appear:

  I want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. After that, I want to arduino to send out necessary via a serial port to labVIEW which should be read using visa read and store in a chain. While I am able to write or read both individually, I can't do it consecutively. I used advanced read and write vi for checking my code, but nothing is helping. The wrong bed 'time delay before execution. " Please let me know where I can go wrong. Also is it possible to write code for hx711 using labVIEW

  1. you need not "\n" on your orders println().  This command adds an end of line character already in the message.

  2. you get the error because you have a loop around your reading.  After the first reading (well technically, the second because of you add an extra line end character), there is nothing left in the port.  As a result, you will get the timeout.

  3. you should really consider using a Structure of the event.  This way you just don't write and read when you press the Write button and you can also use the structure of the event to make the loop to stop.  I also go up to close the port inside the stop-> value Change event.

  

• difference of initial value of string between the steps in the process and an external instance of LabWindows/CVI

  Hello

  I'm curious to know what I see using TestStand, LabWindows/2013 2013 with regard to initial in TestStand string values when you perform the steps in the process or an external instance of LabWindows/CVI.

  I have a step (CVI) string value that is used to check an array of characters stored in an EEPROM to test.  I pass on the Step.Result.String in the CVI by reference.  I then read the table charater of the EEPROM in the chain (Step.Result.String).  The string is then compared against the limit as specified in the test step breast.

  When I run this test step to perform the steps in the process selected in the popup Configuration of the adapter of LabWindows/CVI, it seems that the memory allocated for the string is filled with null characters.  Which is what I expected.

  When I run this test step to execute the steps in an external instance of LabWindows/CVI iselected of the Configuration of the adapter of LabWindows/CVI popup, it seems that the memory allocated for the string is filled with something else.  That is not what I expected.  For example what I see in the memory, it's the first characher is one byte NULL but the remaining bytes are some other values, as shown below:

  F0 00 AD BA 0D F0 AD BA 0D F0 AD BA 0D AD BA 0D AD BA 0D BA 0D AD F0 F0 F0
  F0 AD BA 0D F0 AD BA 0D F0 AD BA 0D F0 AD 0D AD BA 0D AD BA 0D F0 F0 F0 BA...

  In my code I make sure to write a null character in the following location table charater I just write in the chain so I have no problem with the test is working properly.  I have remove the writing from my code null character and was able to verity that the test passes when executing the steps in the process and fails during execution of the steps in an external instance of LabWindows/CVI.

  The returned string contains what I wrote for her, and then the rest of the string is filled with the values that are in the memory allocated for the string.

  Here's my Question: is this the expected behavior for the original string values in TestStand between both types of stage performances?

  Thank you

  Chris Young

  In general teststand not Initializes the unused portion of the string buffer, so it is expected that the values of the memory after character no endpoint will be different, or even to each call. If you happen to be get zeros after the null terminator which was probably due to random character (i.e. the memory allocated just arrived already having zeros in there) or perhaps a debug setting you use perhaps in the Visual C runtime (if you are debugging the process in visual studio or modify visual C runtime heap parameter). TestStand is not initializaing memory after the null terminator character in both cases (I checked the code).

• Variables of unique process and EVS?

  Hello

  I used variable shared unique process and shared network variables in a project with a host PC and a cRIO.

  Is it possible to host the variable engine shared on the PC and still have the cRIO using process variables unique shared when the PC is turned off, and therefore the EVS is not available?

  Reading the documentation, I think it's okay, but I don't know, I'd check myself but the cRIO isn't available .

  Thank you very much

  Steve.

  Hello Steve,.

  Here is a link to a KB which has a note that a shared variable unique process does not use the Shared variable engine.

  http://digital.NI.com/public.nsf/allkb/1F45A4298B976F4A86257168006EA0C3?OpenDocument

  The reason is that it would add additional overhead to the application.

  One thing to remember of thought, it is that when the VI on the cRIO comes to use a shared variable of the network and the engine is not available this VI will throw an error.

  With respect,
