Issue about tracking behavior, when use tracker

when using the tracking behavior, when whe choose to simply click on analyze and when to apply and use a tracker

The link I provided is the user manual section about tracking. It has the workflow for stabalizing.
http://help.apple.com/motion/mac/5.0.5/#motn18190529
The section on strategies to improve tracking is important, also.

Question about the CSS behavior when using layer 3 sticky and sticky table

Hi everyone,
I have a question about the CSS behavior when using layer 3 sticky and sticky table is full.
If I configure layer 3 sticky and specify the inactivity timeout as below, how does the CSS
handle subsequent needed sticky requests ?
advanced-balance sticky-srcip
sticky-inact-timeout 30
CSS document says that
Note:
If you use the sticky-inact-timeout command to specify the inactivity timeout
period on a sticky connection, when the sticky table becomes full and none of
the entries have expired from the sticky table, the CSS rejects subsequent
needed sticky requests.
My question is what is the next reaction by doing the CSS if the CSS is in the
following condition:
when the sticky table becomes full and none of the entries have expired from
the sticky table, the CSS rejects subsequent needed sticky requests
Does CSS just rejects/drops subsequent needed sticky requests ?
or
Does CSS does not stick subsequence requests to particular service but CSS forward
subsequence requests with round-robin basis ? which means if the sticky table is full,
the CSS just works round-robin load balancing fashion for subsequence requests ?
Your information would be appreciated.
Best regards,

Hello,
There is a good document explaining this on Cisco web site
http://www.cisco.com/en/US/products/hw/contnetw/ps789/products_tech_note09186a0080094b4b.shtml
It depends if the sticky-inact-timeout is used or not. If not, it's FIFO (the oldest entry in the sticky table is removed). If yes, the CSS will reject the next sticky request.

DBMS_XMLQuery behavior when using stored function within cursor select

Consider the following SQL Statement
select t1.id
, t1.name
, cursor ( select t2.id
from tab t2
where t2.t1_id
= t1.id
and validate(t2.xyz,:bd1)
= 1
from tab t1
where t1.id = :bd2
DBMS_XMLQuery is used to create a context and to bind the appropriate values. In this case 'validate' is a stored function. I get the following error message upon execution:
ORA-29532: Java call terminated by uncaught Java exception:
java.sql.SQLException: Missing IN or OUT parameter at index:: 1
Issuing a similar statement in SQL*Plus works fine. I was wondering whether this is a known issue when using a stored function in the cursor select statement in the context of DBMS_XMLQuery or whether I'm doing something wrong.

Hi Jan,
This problem has been identified and fixed. The fix should be available in the next release. Thank you for bringing this up to our attention.

Odd behavior when using custom Composite/CompositeContext and antialiasing

Hi,
I created a custom Composite/CompositeContext class and when I use it with antialiasing it causes a black bar to appear. I seems it has nothing to do with the compose() code but just that fact that I set my own Composite object. The submitted code will show you what I mean. There are 3 check boxes 1) allows to use the custom Composite object, 2) allows to ignore the compose() code in the CompositeContext and 3) toggles the antialiasing flag in the rendering hints. When the antialiasing flag is set and the Composite object is used the bar appears regardless of if the compose() method is executed or not. If the Composite object is not used the bar goes away.
The Composite/CompositeContext class performs clipping and gradient paint using a Ellipse2D.Float instance.
a) When the Composite is not used the code does a rectangular fill.
b) When the Composite is used it should clip the rectangular fill to only the inside of a circle and do a gradient merge of background color and current color.
c) If the compose() method is ignored then only the background is painted.
d) When antialiasing is turned on the black bar appears, i) if you ignore the compose() method it remains, ii) if you do not use the Composite object the bar disappears (???)
NOTE: the compose method's code is only for illustration purposes, I know that AlphaComposite, clipping and/or Gradient paint can be used to do what the example does. What I am trying to find out is why the fact of simply using my Composite object with antialiasing will cause the odd behavior. Been trying to figure it out but haven't, any help is appreciated.
Thx.

I got a better version to work as expected. Though there will probably be issues with the transformation to display coordinates as mentioned before. At least figured out some of the kinks of using a custom Composite/CompositeContext object.

Issue with instant ringback when using sip trunk to SP

Hi all,
We use CUCM 8.0.2.
We have a SIP trunk to a SP connected via one of our Cisco 2911 routers configured as a CUBE.
Cisco IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.0(1)M3, RELEASE SOFTWARE (fc2)

data           None            None
We also have several ISDN lines that run out via various Cisco routers configured as H323 gateways.
We use 7945 and CIPC for our phones.
We're having an issue with calls going via the SIP trunk where we hear ringing instantly after dialling - but before the actual device at the other end starts ringing (considerable difference).
Using the SIP trunk: If I make a call to my mobile phone - I hear ringing instantly - about 3 rings before my mobile phone actually starts ringing - undesireable.
Using H323 gateway: If I make a call to my mobile phone - I hear silence for a bit - then ringing when the mobile starts ringing - desired.
Using SIP trunk: If I make a call to a landline that is ready - it rings instantly for at least 1 ring - before the actual phone I'm calling starts ringing - undesireable.
Using H323 gateway: There is a momentary pause before hearing ringing on my phone and the phone I dialled - desired.
Using SIP trunk: If I make a call to a landline that is off-hook (with no call-waiting/etc.) - it rings once and then returns the busy signal (the worst issue) - undesireable.
Using H323 gateway: There is a momentary pause before hearing busy signal - desired.
Phone to phone internally (same network): Operates as expected (instantly rings locally and on the phone I'm calling). Between phones that utilise the SIP trunk and phones that utilise the H323 gateways within the same network - communication is instant and as expected.
Any ideas why this happens and how to stop it?
I want it to not ring until the situation is known and that it can provide the appropriate feedback (ringing/busy/etc.).

Any help or a point in the right direction would be greatly appreciated.
Cheers,

I ended up resolving this issue as follows:
In CUCM, under Device > Device Settings > SIP Profile.
I modifed the profile relevant to my SIP trunk, under the "Trunk Specific Configuration", I set "SIP Rel1XX Options" from "Disabled" to "Send PRACK if 1xx Contains SDP".
Now, I get the expected delay before hearing ringback.
Solved!

Strange behavior when using Labview to collect data from Tektronix tds8200 oscilloscope

I have hit a wall in trying to figure this one out. The problem I am having is that my program does not start the oscilloscope when it should.
I am using a Tektronix TDS8200 oscilloscope. My goal is to collect waveform data from the oscilloscope using Labview. My program first initializes and configures the oscilloscope; this part of the program runs fine.
The second part of the program begins the data aquisition using the 'tktds8k Start or Stop Aquisitions.vi' function, which is equivalent to pressing the Run button on the scope. The 'tktds8k Get Waveform.vi' function is then used and should ideally return the data, which I have connected to a waveform graph for visualization.
When I run my program, the first part executes without issue, but as soon as the program gets to the Get Waveform function, the Run button on the scope, which is green when running, turns off; the program then times out, and no data is collected.
Here's where it gets weird. I went through some debugging to try and figure this out, and I put breakpoints on both the Start and Get Waveform functions so that I could step through the later part of the program. The program continues through the Start function, and the Run button on the scope is green. The breakpoint for the Get Waveform function is reached, and when I press continue, the Run button turns off and then turns back on almost immediately; the data is collected, the waveform graph is displayed, and the program exits without an error.
I thought timing might be the issue, so I made the program wait as long as 5 seconds between the Start and Get Waveform functions, and that did not work. I also tried moving the Start function to before the configuration functions, and removing the Start function altogether; neither method worked.
Are there any thoughts on why the program works when I have the breakpoints enabled and doesn't when the breakpoints are disabled? I am sure that there is an easy fix, but I haven't been able to find a solution.
I have attached a pdf containg information on the Oscilloscope functions (tktds8k.pdf), and I have also attached my program.
Solved!

Thank you for the swift replies.
After Bill asked about the ID Query, I decided to try a few things that I had already gone over just to double check. I was suspspicious that timing was the source of the error. Using a timed while loop, I set the wait time to 10 seconds and got results. As it turns out, 5 seconds is not long enough, but 8 seconds is a sufficient wait time for the program to work. With the problem solved, I am still mystified as to why waiting 8 seconds is required.
I think that the oscilloscope must be given sufficient time to display the signal on-screen before the Start Aquistion or Get Waveform functions are used. With this logic in mind, the breakpoints were acting as a sort of wait, allowing the signal to be displayed before continuing through the program.
In response to Jeff, I am indeed using an external direct trigger. The hardware is sound, but apparently, my coding could use some work.
I have attached the modified code. I am certain that there is a more elegant solution to the timing than simply slapping a timed while loop on the code. Any suggestions?

Question about file size when using "Export for Web"

Hi!
I created a .mov file and worked to get a great balance between file size and quality so that I could deliver it via the web and make it easier for end users to see the video on a slower connection.
My question: When I use "Export for Web," my .mov file is converted into a very large .m4v file--more than double the size of the original file. I know that this export option is to optimize the file for a wide variety of users/internet speeds. Am I correct in guessing that the end size is not an issue? I would post the .mov file instead, but I really like the option of embedding into a html page along with the "click to play" option.
Bottom line--is it better to post the smaller .mov file that i originally started with or to go ahead and link to the bigger .m4v file that was created with the "Export for Web" option?

"Export for Web" is a feature of QuickTime Pro and it makes 4 files and the html page code for easy copy/paste Web page editing.
The very first file is called a "reference movie" and it links to the other 3 files (56kbps, 900kbps and 1.5Mbps). It, and the page code, "read" the connection speed of the viewing hardware and "serve up" the correct file based on that connection speed.
In nearly all cases the "Desktop" version would still be smaller in file size than the original source. The times the file would "increase" in file size would be when an already compressed was used as the source file. You can find out more about your source file by opening it in QuickTime Player and viewing the Movie Inspector window information.
There are dozens of other html "tricks" that could be used if your source file is already compressed but you want a different display size:
Page code to show "aspect" or scale="tofit". This code allows values "outside" of those found in the actual QuickTime file be used for the Web page display. A 320X240 QuickTime .mov file looks pretty good at double size (640X480) but the file size would still be that of the source file.
"Poster Movie" is another html trick that loads the Web based file directly in the QuickTime Player application (bypassing Web page layout restrictions). These files are also known as "Presentation Movies".
Another method is the QuickTime Media Link file (.qtl). These are simple text based files that are used as a "direct link". These use simple XML (Extensible Markup Language) and are easily created in any text editing application. The simple syntax has amazing control over a simple QuickTime .mov file. You can launch (and quit) the QuickTime Player, display at other dimensions and even embed "links" inside the display.
Some of my files as examples:
http://homepage.mac.com/kkirkster/Lemon_Trees/ a "Poster Movie" style.
http://homepage.mac.com/kkirkster/.Public/RedneckTexasChristmas.qtl
A QuickTime Media Link file. A tiny file should download to the viewing machine, launch QuickTime Player, present the movie and it even includes a "link" to my Web page.
Edit: It appears you must now double click the .qtl download to launch QuickTime.

DHCP lease issue for PPPoA sessions when using external DHCP server

We used to use the Cisco 7206VXR's DHCP server to hand out leases, and when we lost several hundred customers on a link, the router was able to get them up and connected with an IP address within minutes.
We switched over to using an external DHCP server so we could have more control over some extended DHCP options, as well as to aggregate all our DHCP traffic. Now, if we lose 100 DSL customers all at once, it takes 90 minutes for them to come up again. They come in a few at at time, until all 100 are back.
We see waves of RADIUS auth's in our RADIUS log (RADIUS has always been handled externally, so nothing changed there), and continuous streams of DHCP requests come in and DHCP offers go out. What seems to be happening is that a whole bunch of modems auth with RADIUS, request IP addresses, but for whatever reason, timeout when they don't all get their lease, drop the connection, and retry the whole process all over again. We purchased a dedicated DHCP server, thinking that was the bottleneck, but performance is about identical.
Here's our config:
interface Virtual-Template1
ip unnumbered Loopback11
ip helper-address a.b.c.d
peer default ip address dhcp
ppp authentication pap
ppp ipcp dns a.b.c.d e.f.g.h
ppp ipcp unique-address
My questions are:
- is there any performance issue with using an external DHCP server and PPPoA
- is there anything in our config that would cause such delays
Frank

GP:
No, the DHCP server is not across a WAN link; there is only a 10/100 switch in between the router and the DHCP server. There are no dropped packets on the interface.
I ended up opening a case with TAC about this issue. While I had the helper address configured in the template, TAC recommeneded that I specify the actual DHCP server with the command "ip dhcp-server x.x.x.x". This eliminates the DHCPBROADCAST (which I've verified). Perhaps the DHCP relay portion of the Cisco router is performed serially, instead of in parallel. By that, I mean, the next DHCPBROADCAST won't go out until there is the response for the first DHCPBROADCAST.
I'll know in a few days when we test again.

Problems about trackpad+keyboard when using Leopard on Macbook Pro

I'm using Macbook Pro Multitouch 2.4 and I have two problems while using this laptop. have anyone same problem with me?
1- about trackpad: I 'm not usually using tapping trackpad, but when I try to use tapping trackpad for a while, trackpad cannot tap. So I must change to click trackpad. When I logging out or restarting, the trackpad can tap again.
2-about keyboard+trackpad: I sometime get freezing keyboard+trackpad excepting power button. But when I close the lid to sleep my laptop and open it again, it return normal but after a while it continue this problem.
I'm using Leopard v1.5.3 although 1.5.2 also have the same situations.
Anybody help me T_T

I found this solution elsewhere on the forum:

Performance issue in Webi rep when using custom object from SAP BW univ

Hi All,
I had to design a report that runs for the previous day and hence we had created a custom object which ranks the dates and then a pre-defined filter which picks the date with highest rank.
the definition for the rank variable(in universe) is as follows:
<expression>Rank([0CALDAY].Currentmember, Order([0CALDAY].Currentmember.Level.Members ,Rank([0CALDAY].Currentmember,[0CALDAY].Currentmember.Level.Members), BDESC))</expression>
Now to the issue I am currently facing,
The report works fine when we ran it on a test environment ie :with small amount of data.
Our production environment has millions of rows of data and when I run the report with filter it just hangs.I think this is because it tries to rank all the dates(to find the max date) and thus resulting in a huge performance issue.
Can someone suggest how this performance issue can be overcome?
I work on BO XI3.1 with SAP BW.
Thanks and Regards,
Smitha.

Hi,
Using a variable on the BW side is not feasible since we want to use the same BW query for a few other reports as well.
Could you please explain what you mean by 'use LAG function'.How can it be used in this scenario?
Thanks and Regards,
Smitha Mohan.

Issue with " " in file when using file adapter

Hi,
Iam using FIle adapter to load the data from file to a table.
Every thing is working fine, but when ever the record in the file has " " in the data it fails.
Eg:
12|"LOG" logo|Y
I am using file adapter with delimiter | and empty in enclosed by.
When I intiate the process it throws saying expected delimited | but could not be found . But I am not using any enclosed by clause so it should not check for | after ".
Any one have any ideas or face this kind of problem.
Thanks

Hi,
Even i faced this issue before...the problem with file adapter is the attribute nxsd:quotedBy takes " as default even if u dont mention it takes the same and now after the quotes it immediately expects | wch is not there in the data and it throws the error...now the fix for the problem is put some symbol for nxsd:quotedBy wch u never expect in the data some thing like less than or greater than symbol ....some thing like below
<element name="FieldTwo" type="string" nxsd:style="terminated"
nxsd:terminatedBy="|" nxsd:quotedBy="<"/>

What about session memory when using BEA Weblogic connection pooling?

Hi,
consider a web application, allowing database connections via a BEA Weblogic 8.1 application server. The app-server is pooling the oracle connections. The oracle database is running in dedicated server mode.
How are the database requests from the web app served by the connection pool from BEA?
1) Does one oracle session serve more than one request simultanously?
2) Does BEA serialize the requests, which means, that a session from the pool is always serving only one request at a time?
If (1) is true, than what about the session memory of Oracle sessions? I understand, that things like package global variables are beeing stored in this session private memory. If (1) is true, the PL/SQL programmer has the same situation, as with programming an Oracle databas in "shared server" mode, that is, he should not use package global variables etc.
Thankful for any ideas...

Reading "Configuring and Using WebLogic JDBC" from weblogic8.1 documentation, I read:
"... Your application "borrows" a connection from the pool, uses it, then returns it to the pool by closing it...."
What do you mean by returning the connection by closing it? Tbe server will either return the connection to the pool or close it...When application code does typical jdbc code, it obtains
a connection via a WebLogic DataSource, which reserves an
unused pooled connection and passes it (transparently wrapped)
to the application. The application uses it, and then closes
it. WebLogic intercepts the close() call via the wrapper, and
puts the DBMS connection back into the WebLogic pool.
The reason, why I as an Oracle programmer ask this is, because every session (=connection)
in Oracle has its own dedicate, private memory for things like global PL/SQL variables.
Now I want to figure out, if you have to careful in programming your databases, when
one Oracle session (=connection) is serving many weblogic requests.It is serving many requests, but always serially. Do note however, that we
also transparently cache/pool prepared and callable statements with the
connection so repeat uses of the connection will be able to get already-made
statements when they call prepareStatement() and prepareCall(). These
long-lived statements will each require a DBMS-side cursor.

Question about static context when using classes

hey there.
i'm pretty new to java an here's my problem:
public class kreise {
     public static void main (String[] args) {
         //creating the circles
         create a = new create(1,4,3);
         create b = new create(7,2,5);
         System.out.println(a);
         System.out.println(b);
         //diameters...unimportant right now
         getDiameter a_ = new getDiameter(a.radius);
         getDiameter b_ = new getDiameter(b.radius);
         System.out.println(a_);
         System.out.println(b_);
         //moving the circles
         double x = 2;
         double y = 9;
         double z = 3;
         a = create.move();
         System.out.println(a);
}creating a circle makes use of the class create which looks like this:
public class create {
    public double k1;
    public double k2;
    public double radius;
    public create(double x,double y,double r) {
        k1 = x;
        k2 = y;
        radius = r;
    public create move() {
        k1 = 1;
        k2 = 1;
        radius = 3;
        return new create (k1,k2,radius);
    public String toString() {
    return "Koordinaten: "+k1+" / "+k2+". Radius: "+radius;
}now that's all totally fine, but when i try to usw create.move to change the circles coordinates the compiler says that the non-static method move() can't be referenced from a static context. so far i've seen that my main() funktion MUST be static. when declaring the doubles k1, k2, and radius in create() static it works, but then of course when having created the second circle it overwrites the first one.
i pretty much have the feeling this is very much a standard beginner problem, but searching for the topic never really brought up my problem exactly. thanks in advance!

You can't access a non-static method from within a static context. So, you have to call move() from outside of the main method. main has to be static because, in short, at least one method has to be static because there haven't been any objects initialized when the program is started. There are more fundamental problems than with just the static context issue.
I'm confused by your code though. You call create.move(), but this would only be possible if move() was static, and from what I see, it's not. Now that's just one part of it. My second issue is that the logic behind the move() method is very messy. You shouldn't return a newly instantiated object, instead it should just change the fields of the current object. Also as a general rule, instance fields should be private; you have them as public, and this would be problematic because anything can access it.
Have you heard of getters and setters? That would be what I recommend.
Now, also, when you are "moving" it, you are basically creating a new circle with completely differently properties; in light of this, I've renamed it change(). Here would be my version of your code:
public class CircleTester {
    public static void main (String[] args)
         //Bad way to do it, but here's one way around it:
         new CircleTester().moveCircle();
    private void moveCircle()     //really a bad method, but for now, it'll do
        Circle a = new Circle(1,4,3);
        Circle b = new Circle(7,2,5);
        System.out.println(a);
        System.out.println(b);
        //diameters. Don't need to have a new getDiameter class
        double a_ = a.getRadius() * 2;     //Instead of doing * 2 each time, you could have a method that just returns the radius * 2
        double b_ = b.getRadius() * 2;
        System.out.println(a_);
        System.out.println(b_);
        //move the circle
        a.change(2,9,3);
        System.out.println(a);
public class Circle {
    private double k1;
    private double k2;
    private double radius;
    public Circle(double x,double y,double r)
        k1 = x;
        k2 = y;
        radius = r;
    public void change(int x, int y, int r)
        k1 = x;
        k2 = y;
        radius = r;
    public String toString()
         return "Koordinaten: "+k1+" / "+k2+". Radius: "+radius;
    public double getRadius()
         return radius;
}On another note, there is already a ellipse class: http://java.sun.com/j2se/1.5.0/docs/api/java/awt/geom/Ellipse2D.html

Issues with sending mail when using 2 email accounts - possible bug?

Hi all,
Having issues with trying to send email from the 3g iPhone. I have 2 IMAP acounts set up on the phone, one
which works fine but when I try to create mail from the primary account as soon as I hit send it exits the mail program and goes back to the home screen.
Both IMAP accounts have identical settings apart from the username and email address. On the primary account there is no sent messages folder on the iPhone whilst there is on the account that works. I've had a look in the advanced settings and it is programmed to store sent messages in the local sent folder which doesn't exist. I've tried selecting it to store in a IMAP folder as I thought maybe it was crashing as the local folder wasn't there but it has the same result.
Have deleted the account and entered the settings back in again to try to coax it to create the local sent folder but cake up with the same problem.
Suggestions are welcome.

You have their SMTP servers mixed up, go to Mail>Preferences>Accounts>Outgoing Mail Server (SMTP), click on the server then choose Edit SMTP Servers and select the correct one for each account. Then check the Use Only This Server box

Strange behavior when using servlet filter with simple index.htm

I am new to J2EE development so please tolerate my ignorance. I have a web application that starts with a simple index.htm file. I am using a servlet filter throughout the website to check for session timeout, redirecting the user to a session expiration page if the session has timed out. When I do something as simple as loading the index.htm page in the browser, the .css file and one image file that are associated, or referenced in the file are somehow corrupted and not being rendered. How do I get the filter to ignore css and image files??? Thank you!!
