• Legacy, causing loss of the scope of variables?

  Hi all
  
  I am working on a class right now, "Block" that has several private variables (call)
  _Color,
  _x,
  FLF,
  _parent...
  
  I have a second class (BlockGenerator range block). In the constructor for BlockGenerator, I call the block using super (parent, x, y) and then I put some of the reactive power inherited from the block class. I'm trying to compile in strict mode, but it is causing the following error message:
  
  1119: access of the property possibly _color not defined through a reference with static type src.game:BlockGenerator.
  
  the error is reported on the following line in the BlockGenerator constructor:
  This ._color = new BlockColor (BlockColor.PLACE_HOLDER);
  
  I've attached some more sample code. Please let me know if anyone has an insight as to why my class BlockGenerator cannot see inside vars inherited from the Block class.
  
  Thank you

  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.

• 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.

• 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

• Need information to set up the XmlDocumentInfoBean process variable?

  Dear team,

  We want to use the QueryForMultipleRowsAsXML service for one of the requirement. For the information this service XML parameter, we'd spend column/xml mappings dynamically.

• Global constants-> process Variables

  I know that you can set the variables as constants in a process that you can manipulate the value via /AdminUI.  These are however by constants of process.  Is it possible to set up constants that are available in a process that is applied to complete installation of the CA?

  For example, I may have some strings that are used in an email through all processes according to which instance LC the process runs.

  As I do now is to define an XML document that exists in the repository. Each instance of LC uses the same XML schema, but the values may differ. I have a process (which may remain the same in all instances of LC) who reads this file and assigns the XML values for process variables.

  Just curious, what about if there was a better way, because Adobe certainly thought about the question of the constants at least on a per-process basis.

  It's a good way to do it.

  We have integrated that that would make it easier than that.

  Essentially, you need a service that can give you these values. Whether a process or a custom component.

• extraction of XML in process variables: (no not the case)

  Hello

  I have a process that takes xml as input data and it must extract the data in process variables, I created. For this I used setvalue processes, where the input parameter is of type xfaform. For this variable, I gave the form as the url of the model (I tried both pdf and the xdp). It loads the schema so file when I checked in the settings of schema. I traced this value (one of the objects in xml) to an another process in the setvalue parameter variable. When I run this process, I don't see the value of the XML object is assigned to the process variable.

  The process is not any mistakes out there. I checked the records as well. I don't know what Miss me in the mappings. I use version 8.2. I have attached ACL that contains the processes and resources. Your help will be very appreciated.

  Thank you

  Chaitanya

  I gave the pdf as a reference model to the xfaform variable. So, will receive navigate the XPath for companyname, it takes thatpath.

  You might be able to break through to the node you want to in xPath Builder, it does not mean that the xPath expression will work based on the data you will receive. You must ensure that you send other xdp data that the xPath will not work.

  Send by email button submit xdp data. Just xml. The difference is that data xdp encapsulates the XML with data/data/xdp tags. What you see when you get off using xPath for an xfaForm variable Designer.

  I think you have two options:

  1 use a normal submit button, set the data to submit to the XDP data and submit URLs using the MAILTO Protocol.

  2 - having an input xml variable and change your XPath to match the structure of the xml file you will receive.

• Get an instance of a single process to another process variable

  Hi Dan,.
  I read some time there is a thread where you said that you have code samples to get an instance of a process to another process variable.

• Packages oversized can cause loss of packets with Dell PC6248

  Hello

  We are seeing packet loss on our voice network which causes the phone sometimes sounds without interruption.  This could be the result of oversized packets (more details below).  On a separate note, if I transfer images using Windows Deployment Services multicast it floods all ports (so I don't more :-).  I had initially activated IGMP but he already caused the switch block at random which may have been connected with firmware earlier.

  We have the fairly simple network:

  1. 3 Dell PC6248s connected in a star (dist 1 and 2 switches access) topology connected together with LAG trunks running latest firmware.
  2. Several VLANS: voice VLAN (100) production data for IP phones, the vlan 1, dev on vlan 5.
  3. IP phones are mainly Aastra 9133i popular with some Polycom.

  I dug more and we are seeing a certain 'oversized packages' on the LAG trunks.  I was wondering if it is at the origin of packets to drop.  If Yes, can I change the MTU size to 1522 (I read that marking adds 4 bytes to the default MTU of 1518) or is there a configuration error I forget somewhere?

  I've been searching through your configuration and try to spot something that may be the cause, but nothing is really jumping on me.

  On the phones they have workstations that connect to their internet access? Or is it just the phone itself?

  One thing we can look at the practice enables jumbo frames. Jumbo frame can be let through all ports and the switch will still go from regular sizes. Extended frames must be activate through all the connections at both ends, once activate on the LAG on a switch, you need to activate on another LAG switch also pass to the back.

  Console (config) # interface range ethernet 1/g1-1/g48

  Console (Config-if) #mtu 9216

  Console (Config-if) #exit

  Console (config) # interface ethernet port-channel 1

  Console (Config-if) #MTU 9216

  Console (Config-if) #exit

  Make sure that you back up the configuration in the startup-config on the switch.

  That a try and see if there is a change in behavior.

  Thank you.

• The range of process buffers affect the audio quality?

  I came across some problems of overload on Logic Pro X and I was suggested to increase "Process buffer range" to "Large" to reduce the errors of overload. My question was whether this parameter will affect my audio quality. Thank you!

  It can affect the latency and should not affect the audio quality.

• 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?

• PID control with big delay in the process variable

  Hello

  My goal is to control the temperature via a valve and heat exchanger. I proceeded variable (temperature) measured from a hose. This temperature should be raised a few degrees with a heat exchanger. So basically I need to order a valve that allows the water to flow through the heat exchanger to raise the temperature to the desired level.

  My original plan was to use a base PID regulation to operate the dispenser. However, it is about 0.5 to 1 minute of delay time in the temperature probe after I opened the valve, which increases the temperature. This leads to a situation where the PID regulation valve fully open during this period (trying to get the temperature rise). Then once the temperature begins to rise it fires quite quickly. PID begins turning the tap off almost immediately, but because of the time delay in the sensor, the temperature exceeds seriously. This led to severe oscillation and at worst unstable processes. I tried to adjust the PID control to "predict" the timer to close the valve in advance to minimize the excess, but failed.

  I would appreciate if anyone has any ideas how to make this type of control with Labview PID functions. I also wonder if there is a better type of control procedure for this scenario as a PID control?

  -Lars

  This is a very common situation in the heating control, and generally PID can be adjusted to make it work. How do you do the tuning? If you do it by trial and errors, you have little chance to succeed. For a slow process with time delay, I like to use the method Cohen Coons, or similar open Ziegler-Nichols-loop method. The idea is that you temporarily remove or disable the PID. Set the valve in a fixed position and wait for the temperature to stabilize. Then, change the setting of the valve and record temperature at regular intervals data until the temperature is stable again to a new value. Use these data to get the initial values of PID using the equations provided by the tuning method you choose.

• Redirection of PL/SQL in application process

  Hi all

  APEX 4.2 - Oracle 10g

  I read the forum here and the web. I'm not getting a redirect page 1 of PL/SQL code successfully in an application process.

  I see in other forums that the developers achieve success with the code below.

  Application process runs a PL/SQL block On anonymous, Load: before header.

  The code I am using has been tested and it fires properly. The problem lies in the actual redirect lines (owa_util.redirect_url).

  Begin

  If [a clause] = True then

  HTP.init;

  owa_util. REDIRECT_URL ('f? p = & APP_ID.:1: & APP_SESSION.');

  apex_application.stop_apex_engine;

  end if;

  END;

  Looks like the browser (IE 8.0.7601.17514) trying to open the following...

  .../f?p=4000:RUN_PAGE:5795566109287:BRANCH_TO_PAGE_ACCEPT:no::FB_FLOW_ID,FB_FLOW_PAGE_ID,F4000_P1_FLOW:1284,4,1284

  Wherever I expect what follows

  Any help appreciated.

  Neil.

  The code works fine.

  The process page is triggered before * every * page load. So there loop of redirection to page 1 and more.

  I added a condition to exclude the redirect if the current page is page 1

  I love an easy solution!
