• How a shared single process variable be FIFO and single element?

  How a variable shared unique process can we both FIFO and the only element at the same time?

  I read the NOR recommended for communication between a loop deterministic and non-deterministic loop.  He is said to use SVariable ingle-process Shared FIFO and single element.  OK I can't have something... because in my mind these two things must be mutually exclusive.  How do you have a single item 1?

  

  What 'RT FIFO activé' means, that when you use the variables shared in a timed loop it actually is written to a RT FIFO created automatically.

  The key here is that generally shared variables are shared resources and can add jitter to deterministic tasks if another loop uses the variable at the same time as your loop of deterministic.

  So here's the takeaway, when shared with RT FIFO active Variables using:

  • Normal loops read and write the shared variable in the same way as they always do.
  
  
  • Call loops read and write a FIFO RT rather
  
  
  • The data is automatically passed between the RT FIFOs and shared in a nondeterministic loop variable

  RT FIFOs exist because their architecture referred to as non-blocking so that when the timed loop trying to access it is guaranteed immediate access to a memory space.

  Does that answer your question?

  Given that the
  introduction of shared variables, whenever I needed a global variable, I have
  use shared unique process variables. But I started now return to
  using the old global variable because I think that there are some significant drawbacks
  to the single shared variable. Here is the ability to search for
  case of variables and also the ability to view or change the value of
  the variable (OK, we have the variable Manager, but I found slow and)
  unstable). My question is, are there reasons to use the new single
  process variable actions on old global variables?

  Dear Terje,

  As you use only the variables on a single system. There is no advantage to the use of unique process shared on Globals variables.

  Infact a global variable uses a little less processing power that a global variable as the implementation of a shared variable single-pocess effect is a global variable with the timestamp feature.
  If you use a shared variable single process, if you don't need the timestamp feature, then disable it to use less processing power.

• variable single process shared with the single element fifo reading arbitrary values

  Hello

  my request in real-time has a motion control loop and a loop of data acquisition. Before the move, the starting position is read once in the motion control loop and recorded as a shared single process with fifo variable single active element (I want to save only the last value). The starting position is then read several times in the loop of the acquisition of data and compared to the actual position. The movement is stopped in the DAQ loop when the difference between the starting position and the actual position reaches a certain displacement of the target.

  Now to my problem: the starting position is read in the loop of data acquisition of the variable correctly shared in the first round after having been written. Then it keeps read an arbitrary value that I have no idea where it came from. How can this happen?

  I summarize: I write the starting position once and then read it several times to calculate the actual shift...

  Thanks in advance for any help! Kind regards

  Hey,.

  It is a strange behavior, usually the variable should return the last value written. You write the variable in another place of the code too? You debug the application?

  What is the RT platform you are working? Version of LabVIEW?

  I suggest using a "functional Global Variable" and see if you still get this random values.

• Unable to get the total number of records processed by the processor of trade rules

  Details of the environment

  ======================

  Disqualification Version: 12.1.3.0.0

  
  

  I use a business rules processor to implement multiple business rules on one record and I am looking for a summary of the number of records increased and does not have a specific rule.

  
  To illustrate:
  Suppose there are 2 rules, invalid number in Column1 and valid number on Column2.
  10 records to process and 3 folders don't rule 1 (valid on column1) and 9 entered failure of rule 2 (valid number on Column2).

  In the browser of result of the processor Business, the number of past records and failed is displayed but is not part of the output of the processor itself. In the example above, there will be 1 pass and 9 fail records and given the values of said the total number of records can be derived which is 10.

  This is why the expected output will be:
  Success of failure
  Rule 1:7 (10-3) 3
  Rule 2: 1 (10-1) 9
  Note: The number of records that failed can be derived from the table of the rule ID but I don't know how to get the total number of records in order to calculate the number of records that a given rule.

  I tried to publish the County of acceptance and rejection in the browser of result of the processor Business in an intermediate table and ask the same intermediate table to get the pass and fail values but Disqualification does not allow to write and read the same intermediary object in a single process. What is the best way to get the number of records total handled by the processor business rules? This kind of attributes (that do not exist only in the browser of result) can be included in the output of the processor in the next version of the Disqualification?

  In addition, the intermediate table contains only 1 sheet with pass and failure values while the exceptions which have individual failure on each rule contains 12 Archives. What would be the best approach to merge a single record into multiple records according to the example below?

  Staging table
  Success of failure
  1 9

  Exception table
  Single ID ID rule
  Rule 1 Record1
  Rule 1 Record2
  Rule 1 record Record3
  Rule 2 Record1

  Exception table with: staging Table data merge
  Rule ID ID Unique Pass Fail Total
  Rule 1 1 9 10 Record1
  Rule 1 1 9 10 Record2
  Recording rule 1 Record3 1 9 10
  Record1 rule 2 1 9 10

• How to get the Instance number as one of the fields in a form of the ADF?

  Hello

  We want the Instance # a request to be part of the shape as an output readonly text.

  (I mean the Forum # who appears in the details of the notice of monitoring process, not the activity number):

  

  )

  How can we get the instance # as part of the form?

  Thank you

  Hi Tali,

  The variable pre-defined information "instanceId".  If you use ADF, the human task data control, expand "Process Info" and drag it onto the form.

  I'm curious to know why you want to do it though.  If it's just so that you can report what you see in the list of "Tasks" of your workspace with instances in the list you see when you click on the tab "Monitoring of the process", I think that there is a better way.  The titles in the follow-up process tab do not have by default "No. of instance.  They may instead be given labels if you use 11.1.1.7 or 12 c.  There is a trick to this and it is shown in this blog post: display of labels for Instance in the follow-up process tab.

• How to get BPEL Instance Id #?

  How to get BPEL Instance Id #? so I can pass this value to the database to get an idea on what id what data processed.

  Hi Guibert,

  Create a schema in your process with content below:

  
  
  xmlns:p = "http://schemas.oracle.com/service/bpel/common".
  xmlns = "http://schemas.oracle.com/service/bpel/common."
  targetNamespace = "http://schemas.oracle.com/service/bpel/common."
  elementFormDefault = "qualified" >
  
  
  
  
  
  
  
  

  
  
  
  
  
  
  

  Now create a type parameters (i.e. ParamsVar) element (root element in above XSD) in your BPELprocess.
  Now using expression in the copy of the assign activity to assign some value (say InstanceID) in the name of the element (IE here in go to article InstanceID and to the name of the section in ParamsVar will come)
  Now the expression in the copy of the assign to assign activity ora: getInstanceId() to the value of the element (IE here in go to article ora: getInstanceId() and in to Value in ParamsVar section will come)

  At this point, your ParamsVar holds the value of your instaceid.

  Now you must edit the def transformation in BPEL (i.e. of section in source view)... as below

  You will get as below once u set source and target variables
  

  You must add bpws:getVariableData('ParamsVar') to the foregoing section

  Then it will look like below

  Now, changing add the following model section before and after the namespace definitions
  
  Here InstanceID will contain the value you pass by transformation.

  Now you can use this setting wherever you want in the transformation as below;

• DSC - event trigger for single shared process Variables

  Hello

  I understand how to set up a Notification of change of value for published network Variables shared so that an event fires when this particular shared Variable changes. However, I can't understand how to do the same for the single shared process Variables. Is it still possible? Can someone shed light on this point, please?

  Thanks in advance.

  -James Pham

  VRspace4,

  Hello! It is not possible to activate alarming for unique shared process Variables. A workaround to set up a Notification of change of value would be to create a network shared variable that reads in your Variable single process, but at this point in time, it could be useful that replace your variable with a variable that is shared on a network.

• single process SV - required generation

  LV 2011 SP1 (only use DAQmx, GPIB, & RS422, not in real time)

  Can't find a quick answer for that.  I know how to build and deploy the network published SV with an EXE but not single-process.

  I inherited someone of code that uses 2 unique processes shared in a unique LVLIB variables.

  (1) the LVLIB container must be included in always included to build?

  (2) are the included MS - SVs automatically included in the EXE?

  (3) the Source file settings requires a line item for the LVLIB?  It can simply be assigned to the item *.exe?

  (4) because there is just no network not associated with SV, I see no reason to include the EVS element for installation of LVRTE. True?

  (5) possibly related: once built and launched, the application cannot locate the typedef used for one of the MS - SV the typedef is used elsewhere in the code (so should be included in any case).

  Thanks for a quick reply.

  Dave

  You did not say what the real problem - exe can not be built at all? It does not start? Something works do not?

  As for point 5), go to the SV type data options and choose Disconnect in typedef (or something like that). I had a lot of problems with SV binded to typedef, they works just not in applications applications (in fact, don't use no SVs in exes and you'll do just fine ).

• Why there is only a single process RFS in v$ managed_standby?

  We build a backup using Oracle Dataguard 10 g server.
  Steps to start this server are:
  SQL > STARTUP NOMOUNT;
  SQL > ALTER DATABASE MOUNT STANDBY DATABASE;
  SQL > ALTER DATABASE RECOVER MANAGED STANDBY BASE DISCONNECT FROM the SESSION.
  
  When we show the process using v$ managed_standby
  SQL > SELECT PROCESS, STATUS, THREAD #, SEQUENCE #, BLOCK #, BLOCKS FROM V$ MANAGED_STANDBY;
  the result is

  There is only a single process RFS. Whereas, when I read articles on the GDO, they mention that there are two methods of RFS.
  
  How to create the RFS another process? Should be to identify what are the parameters?

• Get FacesContext Instance in HTTP servlet, running before filter faces?

  Hello!
  
  I have a HTTP servlet faces filter before running in my application (ADF BC 10.1.3.3). I would like to get an instance of my Module from the Application of this servlet to perform some published methods, I have in my App Module. The problem is that when trying to call FacesContext.getCurrentInstance () .getApplication () throws nullPointerException for FacesContext.getCurrentInstance () returns null. I did some research on it and found that it is because my http servlet runs before the Faces servlet and so I can't get a reference to the FacesContext in this way.
  
  I also found this blog: http://www.thoughtsabout.net/blog/archives/000033.html on how to access the context of faces and backup the beans in a servlet filter. I wonder if anyone has any ideas on this is not not a good approach? Is there a better way to do this? Otherwise, it is a good practice, this post can serve as a tip for someone trying to do a similar thing :).
  
  Thank you
  Kind regards!
  
  BB

  BB,

  If you need an application module in a servlet filter, I'm not sure that I have use the FacesContext at all (I guess you are trying to get a reference to an AM by the binding container). Why not just use normal calls (createRootApplicationModule and release) to get it?

  If Miss me something, feel free to correct me ;)

• Regulator PID very slow to reach the value Point and zeros process Variable when it should not

  Hello

  I am using a PID controller to regulate the emission of a filament current in an ion gauge, but I'm running into several problems.

  The first and less important, are the controller of PID VI takes at least 5 minutes to get the current where it needs to be.  Is it possible to speed this up?

  The second and more important, are that the PID controller tends to zero the process variable before you start the process of getting the close process of the target value variable.  This can be seen in the attached VI: I write 5.8 volts voltage filament - something I did at the beginning to try to get the controller PID for the process close to the target faster - value variable but when the PID controller starts to do his thing, he kills the tension before anything, rather than rise of 5.8 V.

  The attached VI is a single which has these problems.  VI actual ion gauge controller I've written has the same problems, but in a form even more frustrating.  I have a while loop set up for the filament voltage to where it should be (using a PID controller) first and foremost, then a loop of data acquisition, which also includes a feedback loop in the form of a PID regulator to maintain the filament voltage.  When the second PID controller starts to run, it concentrates the tension that the earlier had set, taking another 5 + minutes to reach the point where we can take data and giving us 5 minutes of false data in the process!

  Does anyone know why PID controllers are behaving like this, and what can I do to fix/work with this behavior?

  Hello

  It seems that PID VI will always be 0 for the first iteration. You can, however, use the advanced PID VI and set up the first iteration in manual mode. After subsequent iterations, you could then define this automatic mode and there will be a transition smoothly. I think this will give you the desired behavior.

• Return TopCPU process variable rule data

  I try to customize the rule runaway_process and have some difficulty to retrieve the values of the data model. The goal is to have an email sent when this rule fires for some hostnames. The scope was pretty easy, but get the values of process variables to be included in the e-mail message is a challenge.

  The rule is defined in the TopCPU table and below that is Process_TopCPU. Can I return the latest value data there with:

  Server.get("DataService").retrieveLatestValue (Scope, "Process_TopCPU"). GetValue()

  However, this seems to return the rows in the table of 5 albums processes. I want to return the details (order, Pct_CPU) from the top of the page process only and looks like you have to go a little further below and pull data from Process_TopCPU_Entry. I do not understand how to return these individual values but... can anyone help with this?

  The difficulty here is that the Observations are so-called Observation complex (several processes CPU high of perception at any time)

  The following Scriptlet will work (assuming you reach on the host object.)

  It will search all ALBUMS of Cpu processes in the current collection that correspond to a specific filter criteria and create a string that contains name and uses CPU for each of them. I hope this will help you to build your own version for your use case.

  // Define the filter closure. you could do this inline but I like to declare this on it's own section for readabillitydef filter = { processEntry->  return processEntry.cpuUsage > 0.03}
  
  // use teh find Observation entries function which is part of the Foglight core functionallity and filter for Processes that use more then 2% CPU in my casedef entries = findObservationEntries(#topCPUProcesses from $scope.cpus#,filter)
  
  // Header def msg =  "Processes with high CPU Usage :\n"
  
  // create a single line for each process using a GString templatemsg += entries.collect{ "Name: $it.command  cpu: ${it.cpuUsage *100} %"}.join("\n")
  
  // return the message return msg  
  

  I've also attached a screenshot which describes the function used
