Simple NTP source question

We have had some issues with our network time, which I tracked down to a closed port on an external firewall. However, in tracking this down, a question came up. We have four sources in our NTP config, including the "undisciplined local clock." Since the local clock on a computer is never really accurate, I expect it to drift after a while. Do I really want that as one of my sources? Should I delete it? CAN I delete it?
Phil

It is probably worth noting that the local clock is forced to be stratum
10, which means it is not likely to ever be used UNLESS nothing else can
be used. Leaving it should not hurt and may keep ntp services from
unnecessarily complaining when bigger problems are happening (like a lack
of network connection to any other sources, which is something you'll
hopefully notice since it probably means a cable fell out of your computer
or your ISP's switch).
Good luck.

Configure Domain Controller ( PDC emulator) as NTP source for Cisco switch 6509

Hi All,
My Org consists of 2 DC one Physical and One Virtual. All Roles are on Physical machine. I ran a W32tm /Query /Configuration command on PDC emulator and the results are confusing.My PDC is using time source VMICTimeProvider a syou can see below.
VMICTimeProvider (Local)
DllName: C:\Windows\System32\vmictimeprovider.dll (Local)
Enabled: 1 (Local)
InputProvider: 1 (Local)
My first Question is that Is it Ok for PDC emulator to use this time source or should I change to some Other source like pool.ntp.org or time.windows.com,0x1.
My Second Question is that I have a core switch cisco 6509 and I want this switch to use my NTP server (PDC emulator ) as NTP source,but at present I cannot as I am getting this error on switch.(no select intersectionTP )
Can Any one help ... Its is urgent
Thanks in Advance

You should not make your DCs sync their time with your Hypervisor. This usually ends with time synchronization problem so I would recommend to disable that on your DCs and domain joined VMs and use an external NTP server to sync time on your PDC while using
your AD forest topology for time sync on other DCs and domain-joined computers.
I have already started a Wiki article that describes how to configure time sync in an AD domain and you might consider using the GPO configuration option that is stated: http://social.technet.microsoft.com/wiki/contents/articles/18573.time-synchronization-in-active-directory-forests.aspx
For the CISCO switch, I would recommend asking them in CISCO forums.

Secondary ip address - using as NTP-Source

Hello,
if i configure a secondary ip address on a primary inerface.
How can i force some services to use this secondary ip address as source-address.
For example, NTP, Tacacs, ... and so on.
I am loooking for something similar to ntp source-interface on routers.
Thanks
Andreas

Hello,
You even do not need to set a secondary ip address.
You can use single IKE identity so the VPN peer is identified by all of its peers with a single IKE identity which is achieved by using a loopback address (always up) that must be advertised by your routing protocol or by the mean of a static route.
This will save resources in the case when crypto map is bound to different interfaces for access link redundancy or in your case when you are planning to change the interface ip address, so the IKE SA will exist between the two peers regardless of which ip address is used.
In the other side you can point IPSec ?set peer? command to the peer loopback interface.
Additional features might help:
- IPSec keepalive/ DPD (Dead Peer Detection), this will intercept peer failure at time.
- Another feature that will clear the IPSec SA if a maximum idle timeout is reached.
I successfully tested the configuration, take a look at routers configuration file.
I hope I answered your question.
Have a good work,
AJN

NTP source interface failure

NTP always uses the outbound interface, regardless of configuration of source interface.
Managed to get it to work by combining the source interface on the server command line. So instead of:
ntp server xxxxx
ntp source Loopback0
we used the command
ntp server xxxx source Loopback0
Be sure to eliminate the other ntp server and source commands.

If you're referring to applets, the command is "source-interface" as an argument to the mail action:
action X mail to "[email protected]" from "[email protected]" server 10.1.1.1 subject "Test" body "this is a test" source-interface Gi0/0

Simple X-fi Question, Please Help

!Simple X-fi Question, Please HelpL I've been looking for an external sound card that is similar to the 2002 Creative Extigy and think I may found it in the Creative X-Fi. I have some questions about the X-fi though. Can the X-fi:
1. Input sound from an optical port
2. Output that sound to 5. surround- Front, surround, center/sub
3. Is the X-Fi stand-alone, external, and powered by a USB or a wall outlet (you do not need a computer hooked up to it)
Basically I want to connect a TosLink optical cable from my Xbox to the X-Fi. That will deli'ver the sound to the X-Fi. Then I want that sound to go to a 5. headset that is connected to the X-fi via 5. front, surround, and center/sub wires. The X-Fi has to be stand-alone and cannot be connected to a PC to do this.
Thank you for your help.

The connector must match, and the connector polarity (plus and minus voltage) must match. Sorry, I don't know if the positive voltage goes on the inside of the connector or the outside. Any wattage of 12 or more should be adequate.

Simple Crop tool question... how do I save the crop section?

Hi,
I have a very simple crop tool question. I'm a photoshop girl usually... so Illustrator is new to me. When I select the crop section I want... how do I save it?... if I select another tool in the tool panel, the crop section disappears and I can't get it back when I re-select Crop tool. If I select Save as... it saves the whole document...and not just my crop section.
Like I said, simple question...but I just don't know the secret to the Illustrator crop tool.
Thanks!

A Simpler, More Direct Question About Merge Joins

This thread is related to Merge Joins Should Be Faster and Merge Join but asks a simpler, more direct question:
Why does merge sort join choose to sort data that is already sorted? Here are some Explain query plans to illustrate my point.
SQL> EXPLAIN PLAN FOR
2 SELECT * FROM spoTriples ORDER BY s;
PLAN_TABLE_OUTPUT
|   0 | SELECT STATEMENT |              |   998K|    35M| 5311   (1)| 00:01:04|
|   1 | INDEX FULL SCAN | PKSPOTRIPLES |   998K|    35M| 5311   (1)| 00:01:04|
---------------------------------------------------------------------------------Notice that the plan does not involve a SORT operation. This is because spoTriples is an Index-Organized Table on the primary key index of (s,p,o), which contains all of the columns in the table. This means the table is already sorted on s, which is the column in the ORDER BY clause. The optimizer is taking advantage of the fact that the table is already sorted, which it should.
Now look at this plan:
SQL> EXPLAIN PLAN FOR
2 SELECT /*+ USE_MERGE(t1 t2) */ t1.s, t2.s
3 FROM spoTriples t1, spoTriples t2
4 WHERE t1.s = t2.s;
Explained.
PLAN_TABLE_OUTPUT
|   0 | SELECT STATEMENT       |              |    11M|   297M|       | 13019 (6)| 00:02:37 |
|   1 | MERGE JOIN            |              |    11M|   297M|       | 13019 (6)| 00:02:37 |
|   2 |   SORT JOIN            |              |   998K|    12M|    38M| 6389 (4)| 00:01:17 |
|   3 |    INDEX FAST FULL SCAN| PKSPOTRIPLES |   998K|    12M|       | 1460 (3)| 00:00:18 |
|* 4 |   SORT JOIN            |              |   998K|    12M|    38M| 6389 (4)| 00:01:17 |
|   5 |    INDEX FAST FULL SCAN| PKSPOTRIPLES |   998K|    12M|       | 1460 (3)| 00:00:18 |
Predicate Information (identified by operation id):
   4 - access("T1"."S"="T2"."S")
       filter("T1"."S"="T2"."S")I'm doing a self join on the column by which the table is sorted. I'm using a hint to force a merge join, but despite the data already being sorted, the optimizer insists on sorting each instance of spoTriples before doing the merge join. The sort should be unnecessary for the same reason that it is unnecessary in the case with the ORDER BY above.
Is there anyway to make Oracle be aware of and take advantage of the fact that it doesn't have to sort this data before merge joining it?

A few simple (?) dimension questions...

Hi, I have a few really simple dimension questions that I just can't figure out in OWB (which I'm just now starting to play with):
1) I'm trying to create a dimension that has no levels or any hierarchy. In the BI tool, I just want this dimension to act as a "pick list" for one of 8 values (DW data snapshot dates for the last 8 weeks...) Users won't summarize by this dimension, or ever have more than 1 week selected at a time. How can I set this type of dimension up?
2) Somewhat related to #1 - just to get something working, I set up a "time in weeks" dimension not as a time dimension, just as a normal user dimension. I then added a single "weeks" level with a surrogate key (using "key" instead of "id"), short desc (as the business key), and long description. Set up a mapping from my source table, everything worked fine. The strange thing I've notcied is that the relational table produced has both a "week_key" column and a "dimension_key" column. How can I get rid of the "dimension_key" column - its just an exact duplicate of the lowest level key column? Note - we will have a dimension table with over 1.3 BILLION rows in our warehouse - so duplicating this column does add a significant amount of overhead - this isn't just an academic problem.
3) related to building this "test" dimension - my source table has 8 records in it. Whenever I run the ETL to populate the dimension table, the surrogate keys end up being key values 9 - 16 instead of 1 - 8. Note this is even if I reset the sequence number to 1 before I start, etc. My understanding is that Oracle uses a variable width number field when storing data - so having this dimension with values 1-8 instead of 9-16 saves approx a byte for every fact table record (which we're predicting will be in the range of 20 - 50 BILLION rows). How can I force the dimension to start numbering at 1?
Thanks in advance,
Scott

Hi
Reg #2, I do not think we can get rid of the "dimension key". It looks like OWB is creating this column as a default Primary Key and hence is not possible to remove this. May be if we build the base Table for dimension as a normal relational table, which will allow us to define our own keys, and then build the "Dimension" using AWM on this relation table may resolve the issue of having duplicate primary keys. Its only a thougt, have not tested though.

Ridiculously simple audio editing question for Garage Band

Ok, so this is really a fundamental
question. It concerns editing technique.
In analog mixing, the editor put
the sounds to be saved in the right
places on each of several tracks --
narration, sound effects, lip sync,
music, etc. The tracks were then
all locked together and the mixer
adjusted the volumes to either save
or reject audio information.
A blank master received the information
and that was your final product,
in sync, sprocket by sprocket, with
the video.
My question, then, is, how do you
do it in digital multitrack such as
Garage Band? Are you aiming to have
4 or 5 tracks all level controlled
or do you simple erase unwanted
sound, or what exactly do you do,
in post production? If you are going
to do a voice over, then you have to
do a mix at some point, not just a
cut and paste. What's the philosophy,
if you don't mind my asking?
Thanks,
Ed

Wow... you gave me flashbacks to a movie soundtrack I scored, with separate reels of tape all synced up and whirling away for final mixdown!
To answer your question as best I can in a paragraph or two, digital mixing is unlimited compared to analog. Whereas tape has a physical limit, you can always add another digital track (there are limitations to digital, but they are becoming harder to reach as systems become increasingly powerful). So no need to erase. Editing is also a breeze. Digital tracks are endlessly malleable, with virtually every parameter available for automation.
Sometimes you might mix down to stems or mix everything down to a stereo master (or alternative mixes) for post production. Similarly, in post, they can deal with huge numbers of digital tracks from different sources.
In terms of a professional workflow, Logic is the more typical choice over Garageband, and includes a number of features designed for scoring to picture: variable sample rates, frame rates, etc.
Gain staging in digital recording is different than in analog, and it requires a different approach to achieve excellent sounding results. But the digital workflow is so much more flexible, forgiving, and economical, that it has been the death-knell for the analog workflow. Infinite bussing, routing, mixing, comping, storing, stemming... infinite possibilities, really!

Simple Java SDK question for server group assignment

I have a snippet of code below in which I am trying to apply the setProcessingServerGroup() and setProcessingServerGroupChoice() methods to my report object. My question should be relatively simple: I believe I need to cast(?) my iObject report object to iProcessingServerGroupInfo per the API in order to use the setProcessingServerGroup() and setProcessingServerGroupChoice() methods, but I'm not sure how to do so.
Can someone please advise how to cast my iObject to iProcessingServerGroupInfo?
Thanks in advance...
Code:
IInfoObject iObject = (IInfoObject) childReports.get(i);
int sgID_view = Integer.parseInt(serverGroupID_view);
int sgPref_view = Integer.parseInt(serverGroupPref_view);
!!!!! CONVERSION / CAST NEEDED HERE !!!!!
iProcessingServerGroupInfo.setProcessingServerGroup(sgID_view);
iProcessingServerGroupInfo.setProcessingServerGroupChoice(sgPref_view);

To followup, I've been able to cast to IShedulingInfo in order to use the setServerGroup() and setServerGroupChoice() methods successfully:
IInfoObject iObject = (IInfoObject) iObjects.get(i);
ISchedulingInfo iSchedulingInfo = iObject.getSchedulingInfo();
iSchedulingInfo.setServerGroup(427);
iSchedulingInfo.setServerGroupChoice(2);
But I don't know how to perform the cast to be able to access the setProcessingServerGroup(), sterProcessingServerGroupChoice() methods.
Any help appreciated.
Thanks!

Simple java architecture question

This should be a simple question to answer but I haven't been able to find a good answer.
I have an application that establishes a network connection with a server and registers event listeners on that connection.
What I want to do is find a way without a busy-wait/while loop to keep the main() thread running so that the listeners can do their job.
Here is a sample of what I've got:
public static void main(String[] args)
SomeConnection conn1 = null;
try
conn1 = new SomeConnection("someaddress");
TrafficManager tm = conn1.getTraffictManager();
TrafficHandler th = tm.createTraffichandler(new MessageListener()
                    public void processMessage(Message message)
                         System.out.println("Received: " + message.toString());
     catch (Exception e)
          e.printStackTrace(System.out);
     conn1.disconnect();
The problem is that the application doesn't stay running to respond to traffic coming across the connection.
Any guidance would be appreciated.
Thanks

Well, what is the job of the MessageListener if it isn't to listen for messages? And apparently it isn't doing that because your application terminates.
Bear in mind that I don't have any idea how any of those four classes work, or even how they are supposed to work. So let me just quote this line from the API documentation of the Thread class which says when your application will terminate:
"All threads that are not daemon threads have died, either by returning from the call to the run method or by throwing an exception that propagates beyond the run method."
That must be the case in your application.

Simple Java Coding Question

I know this is a simple question, but I can't search for the answer to this because it involves syntax that Google and the like don't seem to search for..
I am trying to figure out some Java code that I have found. I would like to know what:
a[--i] and a[++j] mean.
My first thought was that they meant to look at the position in the array one less (or more) than i (j). But that doesn't seem to be the case. A is an array of Strings, if that matters...
Thanks for you help.

It mean increase/decrease the int i/j by 1. This is done before it gets you the value of a[]. for example if i=5 and you said a[--i] it is really a[4] and i is now equal to 4;

Simple Java EJB question.

When it comes to EJB v3 Remote and Local interfaces,
(With JBoss EJB Container Software in mind, for this question,)
-Does the Remote interface for the EJB include method signatures from the Bean class
-that are to be seen
-that are to be hidden?
-Does the Local interface for the EJB include method signatures from the Bean class
-that are to be seen
-that are to be hidden?
Which is which for
-EJB 2.1 ?
-EJB 3.x ?
- is EJB 3.x reverse compatible in that it allows use of the javax.ejb.* interfaces,
and would accept a EJB 2.1 approach, or does it force one to use Annotations
exclusively?

Simple Task - Syntax Question (how do you pass variables from one component to another component - databinding)?

Hi all,
I'm trying to pass some width/height/URLs from a Video Player component to a Social Bookmarking component's embed text input field. (for people to grab and share videos).
I know this is a simple task, but it's the end of the day and I seem to be having a brain failure... What's the syntax to achieve this? Do I have to import the video player component? These widths/heights/URLs are all being dynamically generated from an XML... should I be pulling it from the XML or just reuse the variables that already exist in the Video Player component?
Here's my code...
Video Player:
[Bindable]
public var source:String = "";
[Bindable]
public var autoPlay:Boolean = false;
[Bindable]
public var fullScreenMode:Boolean = false;
[Bindable]
public var clipTag:String = "_movie";
