What is the recommended data type (decimal, float, or real) for Engineering design data?

Hi,
I'm creating a database to store engineering design data. I've created the table with fields using decimal. In my searches, decimal is recommended for financial applications since it stores an exact representation of the number. My question
is would float or real be more recommended for engineering applications as it involves calculations and also the user cannot tell the exact precision of the data such as how many decimal places to the right?
Thanks.

Affirmative, float and real are probably better for engineering applications.
Discuss the issue with the engineers.

Very important is the span column paragraph property which allows to span several columns in a text frame or to split a column in several sub columns.
Very important is the tag feature, which is also important for creating PDFs with unlimited access.
A lot of problems with footnotes and page layout have been solved due to a better text engine. Up to CS5.5 it could happen that a footnote could force a page be empty when a document was opened.
With CS5 rounded frame corners which are editable were introduced.
Object Styles have been completed since CS3.
Content tools to create linked content were introduced. You need only to change the original content (text or image) and all linked content will be updated as any other link. The linked content can be in the same and in any other document.
Since CS5.5 it is much easier to anchor frames in a text flow with the little at the top of a frame symbol.

What is the recommended way to handle mouse click events for custom nodes that subclass Panes?

Hi,
I have created a custom node that is a StackPane containing a Label on top of a Polygon.
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Polygon;
public class CustomHexagon extends StackPane {
    private Polygon hexagon;
    private Label overlayText;
    public CustomHexagon( String text, double... points ) {
        this.hexagon = new Polygon( points );
        this.overlayText = new Label( text );
        overlayText.setStyle( "-fx-font-weight: bold;" );
        hexagon.setStroke( Color.GREEN );
        hexagon.setStrokeWidth( 5.0 );
        hexagon.setFill( Color.WHITE );
        this.getChildren().addAll( hexagon, overlayText );
// Lays out the node where it should be according to the points provided for the Polygon.
        this.setLayoutX( points[0] - getLayoutBounds().getMinX() );
        this.setLayoutY( points[1] - getLayoutBounds().getMinY() );
// Show the border of the StackPane.
        this.setStyle( "-fx-border-color: black; -fx-border-width: 1; -fx-border-style: dashed;");
    public String getOverlayText() {
        return overlayText.getText();
I want to display a tesselation of these custom hexagons. Because a CustomHexagon is a StackPane, not a Polygon, MouseClick events can be picked up when the mouse is clicked outside of the stroke of the hexagon but still within the StackPane (which takes up a rectangle larger than the hexagon). The following program demonstrates this.
public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        Group root = new Group();
        CustomHexagon[] hexagons = {

After running this program, when one clicks within the intersection of two StackPanes (borders shown by dashed lines), the target of the mouse click event will be the StackPane on top as determined by the order in which they were added to their parent.
This is a problem because there is only a small "T" shaped area within each hexagon that when clicked will target that hexagon with an event, rather than adjacent nodes.
I would appreciate any reccomendations to solve this problem.
Thanks,

What is the recommended way to obtain tracking data from carriers post XSI

We currently run an old version of SAP Business Connector. We are in the process of migrating all interfaces off BC onto PI. The one remaining interface we have problems is the XSI (Express Delivery Interface) interface we have with ECC06 and UPS via the BC server. The interface works but is not stable and we would like to decommission it if we are able.
I'm not 100% clear but it appears that XSI is no longer the recommended solution for obtaining tracking data from carriers. What is the recommend method today? We'd be happy to use a PI or ABAP solution but would prefer a standard solution that was supported by SAP and UPS.

Using Time Machine is the simplest way to back up.

If it's DOS/FAT32, you can only size file sizes up to 4GB.
If you are using it on a Mac only, format it Mac OS X HFS+.

What is the recommended way for persisting JMS messages?

What is the recommended way for persisting JMS messages?. As per the IMQ admin documentation , using the default built-in persistence type which is through unix flat files is much efficient and faster, compared to the database persistence .

Any thoughts?

From the output, you are using imq 2.0. In that release
the key used to persist a durable subscriber in the database
table has a limit of 100 characters. The output shows that
your value is:

esponse%2C+JMQDestinationDescription%3DA+Description+for+the+Destination+Object%7D:
which is much longer than 100 characters.
You might want to shorten the string you use for the
durable name.
And yes, the default file-based persistence store is
more efficient when compared to the plugged-in persistence
through a database.

WHat is the best index type for non uniqueness / Varchar columns in SQL 2008 R2

Hello All Greetings,
Please help me here with my doubt,
in my table i have two columns about a million rows, it has about 20 columns in it, three columns with name as Period, Gender so most of the time these two columns use in where clause,
Gender will contain Either M or F , Period contains YYYY-Month (2013-December, 2013-August) etc so i would like to add a Index to these two columns so that in will increase the performance, so please let me know what type of indexes i need to add to
these columns in the table,
please note that only one time we will add data to the table which will take only 2 minutes but we query the table every day
so my question what is the best index type that i need to create on columns with non uniqueness values in the column.,
Thank you In Advance,
Milan

There is nothing whatever wrong with creating an index on a VARCHAR column, or set of columns.
Regarding the performance of VARCHAR/INT, as with everything in a RDBMS, it depends on what you are doing. What you may be thinking of is the fact that clustering a table on a VARCHAR key is (in SQL Server) marginally less efficient than clustering on a monotonically
increasing numerical key, and can introduce fragmentation.
Or you may be thinking of what you have heard about writing JOINs on VARCHAR columns - it is true, it is a little less efficient than a JOIN on numeric type, but it is only a little less efficient, nothing that would lead you to never join on varchar cols.
None of this does not mean that you should not create indexes on VARCHAR columns. A needed index on a VARCHAR column will boost query performance, often by orders of magnitude. If you need an index on a VARCHAR, create it. It makes no sense to try to find an
integer column to create the index on - the engine will never use it.

What is the recommended way to do multiple channel, single point sampling for control with an NI PCI-6255 in RLP?

Hello,
I am writing a driver for the M-series NI PCI-6255 for QNX. I have downloaded the MHDDK and have all the examples working. I have also enhanced the examples to do interrupt handling (e.g. on AI_FIFO interrupt or DMA Ring Buffer interrupt). My ultimate goal is to write a driver that I can use for closed-loop control at 500 Hz using all 80 channels of the NI PCI-6255. I may also need to synchronize each scan with a NI PCIe-7841R card for which I've already written a driver. I want an interrupt-driven solution (be it programmed I/O on an interrupt or DMA that generates an interrupt) so that the CPU is available to other threads while the 80 analog inputs are being read (since it takes quite a while). I also want to minimize the number of interrupts. Basically, I will need to collect one sample from all 80 channels every 2 milliseconds.
There are many different options available to do so, but what is the recommended technique for the NI PCI-6255 card? I tried using the AI FIFO interrupt without DMA, but it seems to interrupt as soon as any data is in the AI FIFO (i.e. not empty condition), rather than when all 80 channels are in the FIFO, so more interrupts are generated than necessary. I tried using DMA in Ring Buffer mode to collect a single sample of 80 channels and interrupting on the DMA Ring Buffer interrupt, which appears to work better except that this technique runs into problems if I cannot copy all the data out of the DMA buffer before the next AI scan begins (because the DMA will start overwriting the buffer as it is in ring buffer mode). If the DMA is not in ring buffer mode or I make the ring buffer larger than one 80-channel sample then I don't have a way to generate an interrupt when one sample has been acquired (which I need, because I'm doing control).
I saw something in the documentation about a DMA Continue mode in which it looks like you can switch between two different buffers (by programming the Base Count/Address with a different address than the current address) automatically and thereby double-buffer the DMA but there is no real documentation or examples on this capability. However, I think it would work better than the Ring Buffer because I could interrupt on the DMA CONT flag presumably and be copying data out of one buffer while it is filling the other buffer.
Another option would be DMA chaining, but again, I cannot find any information on these features specific to the NI DAQs.
I tried interrupting on AI STOP figuring that I could get a single interrupt for each scan, but that doesn't appear to work as expected.
I know that DAQmx on Windows has the ability to do such single sample, multiple channel tasks at a fixed rate so the hardware must support it.
Any suggestions would be appreciated.
Thanks.

Hello,
The interrupt that will happen nearest the times that you need is the AI_Start_Interrupt in the Interrupt_A group. This interrupt will occur with each sample clock. By the second time this interrupt fires, the AI FIFO should have the samples from the first conversion. If it is easier to use programmed IO, you can read the samples out of the FIFO until you get all 80.
Additionally, you can set the DMA to send samples as soon as the FIFO is no longer empty...instead of waiting for half full or full. This change will reduce latency for your control loop. You can set AI_FIFO_Mode in AI_Mode_3_Register to 0. By the second time this interrupt fires, you should be able to check how much data is in the DMA ring buffer and read the 80 samples when they are available. You can make the ring buffer larger than 80 samples if you see data getting overwritten.
There is no interrupt associated with 80 samples being available in the FIFO or 80 samples being available/transferred by DMA to the host. X Series has much more flexibility with these interrupts.
I hope this helps!

What is the recommended way of connecting to repository out of WebDAV, RMI, JNDI and JCA connector ?

What is the recommended way of connecting to repository out of WebDAV, RMI, JNDI, and JCA connector possibilities provided by CQ 5.5?

Hi dp_adusumalli,
I recognized your list of ~8 questions you posted at around the same time, as I received that same list in our customer implementation from Arif A., from the India team, visiting San Jose. :-)
I provided him feedback for most of the questions, so please check back with Arif for that info.
For this particular question, can you provide specifics for the types of interactions you are interested in?
Understanding the kinds of things you need to achieve will help determine which of the CQ/CRX interfaces is best suited for the task(s).
I've collated a few points on this subject on this page:

It looks you are new to PI,
you have to develop scenario end to end, by creating source data type and target data type(if you have XSD's not required),then use Graphical mapping (message mapping) to map source and target structures.
Search in sdn for one end to end scenario you will understand easily

Is there a risk of setting a console connection timeout and what is the recommended setting?

Is there a risk of setting a console connection timeout and what is the recommended setting? Please suggest if there is any best prctice documentation that can be referred.

Hi Henrik
depend on what you need or what your security policy says for my lab gear i use 60 minutes. because i know how can access this. if you have gear outside in insecure space set it to a minimum or disable the console. everybody how can access your gear can break in. simple restart and boot w/o config. and you are in.
it realy depends how secure is your space and how much security you need.
and than the settings for policy have to match, what sec do you have if your console login and logout is secure. but when you restart you can simple break in by starting w/o config and than load it.

What is the recommended length of the cable in between the GPIB instrument and GPIB-USB card.

hi,
we are planning to use GPIB-USB Controller in our application by replacing the existing GPIB-PCI controller. Our GPIB instrument doesn't have the standard IEEE GPIB Connector. So, we will have to connect one more cable in between GPIB-USB controller and the GPIB Instrument. I just want to know what is the recommended lenth of the cable that can be connected in between the GPIB instrument and the GPIB-USB card. Could anybody please help me?
Thanks,
Rajaram

Page 730 in the 2001 catalog gives detailed cabling requirements for the GPIB bus. It's usually best to keep the length 2meters or less.

What is the recommended ratio of publish nodes to dispatcher web servers for CQ5.5?

What is the recommended ratio of publish nodes to dispatcher web servers for CQ5.5?
We are getting conflicting opinions on this form the field. I realize this is a loaded question. I'd like to see how Adobe presents this opinion. In the past scaling at the webserver level was only loosely tied to the publishing layer. Now it seems as dynamic functionality increases the ratio is getting closer to 1:1.
Also,I'd like to know in what use cases this load on publisher increases dramatically.
