• Oracle Utilities active work and management (WAM) - application Cluster vs Non Clutered

  I installed WAM on a three-node cluster, with a footstool of Server WebLogic Administration Console on the node 1, but WLS_FORMS managed server on node 1, 2 and 3. I need to break 3 node in the cluster, as the company needs to use it for testing idepentantly. I have already built a new instance of WAM database for this, but I don't know how to break 3 node in the cluster and run with its own Web Server Admin logic.

  Does anyone have any advice or learn more about me.

  Thanks in advance

  Hello

  Of after your description it seems that it is only a single domain configured which has wls_forms tuned to 3 knots.

  In this case, you can't break wls_forms on node3 to have its own server admin.

  My suggestion is to stop wls_forms on node3 and configure a new area dedicated to node 3 with an administrator of the server and the managed Forms Server.

  Thank you

• Confusion over the memory of a bunch of Java and WLS_FORMS

  Hi all
  
  Background first:
  
  Oracle Forms/Reports 11.1.2 64-bit
  WebLogic Server 10.3.6
  JDK 1.6 update 37 64-bit
  Microsoft Windows 2008 R2
  Using nodemanager to start/stop the servers managed
  
  After reading all the documentation and searched this forum and the Internet for advice, I'm still totally confused about how best to make use of memory on the server (the server I'm working now on a 8 GB). Two trains of thought that I discovered in my research:
  
  (1) do not change the size of Javaheap at all (stick with the default values) and just create additional managed servers on the same machine.
  
  (2) increase the size of the heap Java for WLS_FORMS
  
  That said, here are my questions:
  
  (A) what is the best practice approach (#1 or #2)?
  
  (B) if it is the #2, what is the approved way to increase the heap size? I tried to add - Xms and arguments - Xmx to the WLS server begin arguments in the WLS console. They are applied when the managed server is started (confirmed in the log file), but because of the way WLS_FORMS is started, there are more - Xms and arguments - Xmx applied after mine, and peaks of Java one last mention if there are duplicates.
  
  1st update: Question #2 seems to be answered by the support notes 1260074.1 (the only place I had not yet looked at)
  
  Thanks for any idea that you can provide. If there is a document that I missed somewhere, I'm happy to be told where it is, and will read and summarize the results here.
  
  Kind regards

  John,

  I'll try to comment on each of your own:

  (1) we had been make some type errors "Unable to contact forms Apache Server" (users see the error "Failed to bridge APACHE server"). The logs showed nothing interesting. I increased the memory allocated using setDomainEnv.cmd, and the error seems to have disappeared. Yes, I know it's a shotgun approach, try something without really having a reason to do it, but it seems to have helped Edit: now I have review of OHS logs instead of WLS_FORMS newspapers, I found the log messages, which brings me to Doc 1380762.1, who tells me that I need a patch. DOH. Oh crikey, forms 11.1.2.1 is out and it came out shortly after that we have downloaded 11.1.2.0 to create these environments. Good and the bad new kind of thing...

  The Apache Bridge error is relatively in line toward the front if you understand what it is say you. It is an error generated by mod_wl_ohs which is the property of SST (Apache). This module is responsible for the relationship between OSH and WLS. The Apache bridge error means that OSH (mod_wls) has been unable to get a response from the managed server WLS he called. Basically, he was unable to cross the bridge ;) The cause could be anything from the managed server does work not, management server is busiest, or there is a problem of network configuration and the server simply didn t hear appeal of OSH.

  It is all described in Note 1304095.1 MOS

  Regarding 11.1.2.1, this can be installed fresh or as a patch on 11.1.2.0. So for machines which currently installed, you can go directly to 11.1.2.1 without having to first install 11.1.2.0.

  
  .

  (2) as tony.g suggested, we are looking for what we should do to solve them "I have n servers with x GB of RAM, what should I do to configure out-of-the-box forms for stability" issue.

  As I said, there is really no 'forms' specific settings associated with how much RAM your machine has. The only exception to this is (although a little indirect) to use the grouping of the JVM. JVM pooling can reduce the size of each execution process memory footprint by moving his calls from java to the pool of the jvm, then common queries of sharing with the other running execution environments. Memory, use of OSH or WLS managed server really has nothing to do directly with the forms. Specifically to the managed server, from a perspective of forms, I would not expect the cost of memory of WLS_FORMS spending a large part due to the workload. I'm expecting increase as the simultaneous load increases, but I would not expect it to be significant. If I had to guess, see an increase of 1 m or less per user wouldn't surprise me (that's just a guess - I don't know what would be the expected values). If we were to use our older scalability guidelines (Oracle), usually we would have suggested that you should consider about 100 sessions by 1 FMV for better performance. Given that v11 uses a newer version of java and scalability is better today, I suspect that you can easily spend a couple of hundred (300 for example) or more before the performance decreases. In addition, the need to add more managed servers would be probably necessary.

  This is discussed in Note 989118.1 MOS

  
  .

  (3) HA is important to us, so we set up a cluster of servers of forms/States with a BLT in front of her. I read in the literature on the management of clusters, cloning of a managed server and with the support, how to increase the memory heap for the WLS_FORMS server. My thought process was 'If Oracle gives me instructions on how to increase the heap memory and how clone managed servers, there must be a scenario in which do have advantage." I'm trying to understand the scenarios in which we would do either of these activities.

  Refer to the note that I mentioned above. As a general rule, if you limit the number of simultaneous sessions less than about 300-400, I think the default settings should be fine. If you think you want to go beyond 300 or 400 per managed server, then probably you need to increase the heap the managed server max. Yet once again, refer to the note that I mentioned earlier.

  See also Note 1260074.1 MOS

  
  .

  I am aware of the JVM pooling (Yes yell us reports) - I still have to this implementation, but it is on my to-do list.

  This is discussed in the [url http://docs.oracle.com/cd/E38115_01/doc.111210/e24477/jvm.htm]Forms Deployment Guide

  
  Hope that helps ;)

• How to make a stacked cluster chart?

  I am creating a cluster diagram, classified by different emails sent to customers (let's call them 1, 2 and 3 Email) and has each kind of stacked e-mail based on the answer (opened, clicked).  Is it possible to have your chart be grouped and stacked?  The x-axis are labeled by the day of the week, and I would be more group by email (1, 2 and 3) every day.

  Thanks in advance for the help!

  Numbers isn't a stacked column cluster chart. But you can use a 3D stacked column and can 'cheat'similar to the way you would in Excel.

  

  The trick is to leave blank lines in the table of data which, when the fill color is removed, the differences between the clusters form.

  I don't understand how to get the labels for each cluster in the right place.  When the two left columns are defined as cluster labels column headers appear where it is indicated in the screenshot, is not ideal.  It is possible that the days of the week may have to be manually labeled with text boxes.

• How to feed a cluster in the mathscript?

  Hi all

  I'm trying to feed a cluster in the mathscript. I found that, if the name of the element in the cluster has no spaces or special characters, it works fine. But it does not work if the name of the cluster components have special characters. That's how Mathscript designed? No work around here?

  Hey dragondiver,

  We hope that you do well today. This document overviews the intended use and the behavior of data with MathScript types.

  Transmission of data in and out of the node MathScript (MathScript RT Module)

  http://zone.NI.com/reference/en-XX/help/373123C-01/lvtextmathmain/ms_passing_data_lv_mathscript/

  So, to answer your question more specifically, the rule for naming elements within a cluster in the node is,

  "You have to tag individual items in the cluster. The labels must begin with an alphabetic character and can contain only alphanumeric characters and underscores, no spaces. »

  It must explain the behavior you're seeing with your code!

• create the cluster

  Hello

  Can we have clusters in the regular similar to LabVIEW user interface designer?

  Thank you.

  Assembly,

  To work around the problem, you can use the flatten in primitive XML string in your web service, and then use the screw of Parsing XML in the Web user interface designer to get your data from cluster:

  

  For an example on the use of the screw of the XML parsing in the generator of the user Web interface, see this example: Arbitrary in LabVIEW Web Interface Builder Web Services call

• Add an element to a cluster without updating all users of the cluster

  I have a cluster that is sent to many different vi. Whenever I have added to this cluster, I need to change every vi that uses it to fix the various controls of input terminals and ungroup by names.

  I'm not change or remove existing items in the source cluster. just to add another element that one worries of the vi "shipwreck" for others, it is simply one don't care. Is it possible to avoid having to fix each "sink" vi when I do this? I would only need to update the vi that uses the new element (which of course, I do anyway).

  In C, I can update, add a member to a typedef'd struct and everything is fine - no problems; How can I do something similar in LV?

  If you branch out a cluster then all sinks must be the same. You should do your cluster a typedef and use the typedef on your screws in this way that you change only one place. Even with the a typedef in C.

  LabVIEW manual contains instructions on how to create and use of typedefs.

• Good practices of FIFO: updated old cluster or create new

  Hello world

  My question is more on "good practices" that really solve a problem.

  I use FIFO to send images and other data from a producer to a consumer.

  I created a cluster which includes all the data that must be sent through the FIFO.

  My question is: can I create a new cluster to each loop of the producer and put this cluster in the FIFO or should I set a shift and then register and update the data of this fallen registry change by sending in the FIFO?

  Below you will find two screenshots that sums up the idea (NB: these aren't the real VI.) We come here to show the general idea).

  If there is a difference (in the way that the computer uses memory for example, or something else...) between these two methods of programming, you will give me some details so that I can understand why to use one over the other, please?

  Thank you very much.

  Best regards.

  Luke

  

  

  I think that there is very little difference in terms of performance (perhaps the registry approach change is slower than sliiightly - but probably not noticeable in most cases).

  The main reason you want to use the shift register approach is that if you update only certain values before sending the data in the queue, those that would be lost if you created a new cluster each time. For example, if 'Directories' was constant, you could just power/updating that once the value to the registry to shift and just update the part "ImageAcquired" of the cluster before you send it in the queue. This also means that if you update your cluster to have more elements (using a type-def, of course), you can be less worried about having to update the individual elements.

  I think it is less a problem of performance (both are valid and effective) and more a matter of maintainability and flexibility.

• History of clear ranking with only refers to the cluster

  I have a group of UI elements that I save them as a strict type def be reused between various programs. I can send data in each of these elements. However, I use graphic waveform instead of waveform graphs so that I can stack data. In my application, the user can select data at different points in time so I need clear history graphic waveform and then update the graph with the necessary values. It works fine if I make a direct reference from the graph but I can't operate using just the reference to the cluster. I get either a mismatch of type if I use a strict reference, or I don't see the historic property at all if an appending reference is used. I've seen people putting this problem before but had not seen the right solutions that work with just the reference of the cluster. Any thoughts?

  In the comic book, do a right-click on the reference to the "table of waveform" and select Create-> constant.  Strictly typed constant wire at the entrance of "class of target" of "more class specific.

• How can I connect a Labview XY (cluster of 2 tables) TestStand 2010 SP1 chart and do appear correctly in the report?

  Patterns of data record TestStand 2010 SP1 default shared this cluster in two tables stored as binary data, resulting in two graphs displayed in the report: one for data and one for X data Y. We need the elements X and Y, couples on the same graph. This cluster is marked for logging as a step output variable. It seems possible to add a table "PROP_XYGRAPH" (similar to the PROP_ANALOGWAVEFORM) to the schema to simplify the other treatment after the database record, but how can we get the Builder, to accept this type of data is displayed correctly? XY graphics come from LabVIEW 2013 SP1 exclusively as a cluster of two matrices, usually between 500 and 1,000 items long.

• How to set the cluster error in postexpression?

  Hello

  I created a c language #-driver that returns a 0 for the pass or - 1 for failure in the functions 'int MyFunction().

  Now I use this function for teststeps.

  Question is: How can I use this returnvalue to set the cluster error?

  So that one - 1 causes an error.

  I think it can be done somehow in the post expression.

  How can I put a

  If (returnvalue == - 1).

  {

  Result.Error.Code = 10100

  Result.Error.Msg = "an error has occurred."

  Result.Error.Occured = True

  }

  Thanks for help

  Hi OnlyOne,

  Check out this example (stored in TS4.0)

  The tower is done using a breakets conditional and literal.

• Instruments cluster interface

  I'm doing my final year project on machine vision based instrument cluster of inspection, I have a good experience with LabVIEW and vision, but this project requires instrumentation running outside of a front vehicle vision real function of inspection to take place, how does take less part interfacing (move hands via USB SE)? should I go for the devices USB CAN go, OR I need to stimulate the cluster as possible what ever I can (speedometer, odometer, etc.), can someone guide me on this point, what the best strategy would be to go on the project?

  Thank you

  Nizamani,

  Here is an article on the use of the virtual ports CAN.

  http://digital.NI.com/public.nsf/allkb/ed9cf160dc07f09f862572c90072b13c?OpenDocument

  You could write two loops which read and write through virtual ports of the CAN. In this way, you can replace the writings and readings with calls to write the material if necessary.

  You can use the USB interface to send images to a physical device. So you could build a virtual instrument listen you while a parallel loop is send information to the virtual device built you.

  Look in the window to find examples to find some simulated devices that may be useful for a starting point. You may be able to find another example posted in the forums or in the area of the developer.

• How to connect a cluster of berries to a waveform graph
