Difference between Design Time & Run Time in JavaBean.

Please tell me that what is the difference between the dsign time and run time in Java Beans.

This is most important when it comes to reflection.
In design time, when not using reflection, you can
include and instantiate classes by importing them and
then calling a constructor:
import java.util.*;
List list = new LinkedList() ;... but when using reflection:
List list = (List)
Class.forName("java.util.LinkedList").newInstance()
;this will compile ("design time") no matter whether
this assignment is valid or not.
A completely wrong statement that will compile
(design time) but not run (run time):
Object o =
Class.forName("ACompletelyInvalidClassName").newInstan
ce() ;I love reflection. Its magic.Design time != compile time/

Difference between Bucket capacity and Time continuous capacity

Can somebody explain the difference in functionality between "Bucket capacity" and "Time continuous capacity" as used in field "Finite capacity" in "PP/DS bucket capacity" tab in Resource?
How will above above two settings work when you have "Block planning" in "Bucket definition" tab in same tab?
Thanks,
Srini

Hello,
The difference between Bucket capacity and Time continuous capacity are:
Time continuous capacity is basically the capacity which is infinite continuous duration in time and you can define the shift intervals and breaks to adjust as per business process e.g. everyday 8 hrs or 16 hrs capacity with lunch time and breaks in between whereas bucket capacity is a discrete capacity and is specified bucket wise. Bucket capacity can be in PPDS as well as SNP. In PPDS it is used specifically for CDP planning or block planning. In SNP it can be used for bucket capacity references as Transport resources, storage resources , bucket planning etc
With respect to Block Planning:
You maintain the blocks using the entire validity of the available capacity of the resource. If you defined buckets from block planning for validity periods in which no blocks are defined, the buckets correspond to technical intervals in which the system schedules on a time-continuous basis.
You can check out the below link for the Block planning with Bucket capacity:

Difference between Designer 6i and Forms 6i?

difference between Designer 6i and Forms 6i?

Designer 6i is more related to the development cycle of a database and the various tools that access the database(from creating the database entity relationship diagrams to creating the physical tables/ddl). Forms 6i is more geared towards data management of the database. Designer 6i has tools to help auto-generate 6i forms.

Difference between Design Time and Runtime

Hi all, very nice to be here sharing knowledge with each other.
I wanna share my practical experince knowledge that is ,
Almost all the properties that can be set at the Design time for any object can also be set at the Run-time using only
GET_object_PROPERTY and SET_object_PROPERTY.
In fact, I have posted the same info on some othr place, too.
Thanx.

Difference between Runtime and Desing time Mapping.

Hi ,
I have read somewhere regarding Mapping between Entity service and External Service ,In that "Both Design time mapping and Runtime mapping is same only difference in User interface".
I have worked on both Design time mapping and Runtime mapping during my work i have found difference as design time mapping we can do in NWDS and Runtime mapping we can do in CAF Runtime Configure.
Here my questions are :
Is it only the difference or anything else?
What is the advantage of Runtime mapping?
Where I can find difference of Design time mapping and Runtime mapping?
If possible explain with nice example
Thanks and Regards,
Suresh B

Hi,
Run Time Mapping: with this feature you can do mapping at run time that is after deployment of your application on the server.That is you can do mapping with out changing your souce code.But with design time mapping you have to change the source code before deployment of your application.

JDeveloper: Viewing a .css on JSP at design-time + run-time

Hi,
As a newbie to JDeveloper, i'm struggling to get a stylesheet reference to work in both the Design view and at run-time. Dragging a stylesheet on to the JSP works fine in the development enviroment, but when the JSP is called from a controlling servlet, the stylesheet doesn't render. From looking on the web it seems i have to use request.getContextPath() to get the path: doing this works at runtime, but in the design view of JDeveloper doesn't show anything (obviously wouldn't because the getContextPath is evaluated at runtime).
Is there a work around so i can see a style sheet rendered in both design & runtime?
Thanks,
Phil

Hi,
Thanks for your reply. When I added my stylesheet (from the component palette) JDev put it in a 'css' folder. When I drag it on to the page it uses ..href = "css/stylesheet.css".. This doesn't work at runtime, neither does href = "/css/stylesheet.css".
To explain the problem better...if I create a new project with 2 jsp files and link them together with Go to page 1 etc this is fine. As soon as I use the mvc method of controlling jsps thorough servlets I can call page 1 fine, but if I linked back to page 2 with the href calling the jsp directly (rather than through a servlet) it won't find the page, because the context root has an extra 'servlet' folder on the path, ie it's looking for page 2 in "Testing-Project-context-root/servlet/page2.jsp", when it's not located in a servlet folder. This is why the css file is not rendering, because it's looking for it in a servlet folder. I can only get round it at the moment by using:
<link type="text/css" rel="stylesheet" href="<%=request.getContextPath()%>/css/stylesheet.css"/>. This of course is no good in the development environment.
Thanks,
Phil

Get the difference between two java.sql.Time values

Hi, I'm developping a web application in which I need to to subtract one java.sql,Time value from another. The two values are stored in a database field of type DateTime. I used following code
java.sql.Time start_time=resultset.getTime("startTime");
java.sql.Time end_time=resultset.getTime("startTime");
java.sql.Time diff=start_time-end_time;
can u give me any comment on this code

Remember what the Date/Time object in Java represents - a single point in time.
Subtracting one from another gives you an amount of time elapsed between the two dates. Fine.
Making a new Date out of that number is incorrect. The number no longer represents a point in time, but rather a duration.
Its like saying "There is 10 seconds difference between the two times, so the time is now 1 Jan 1970, 00:00:10 GMT".
The simple and stupid calculation is to take the milliseconds difference, and divide it to get to a more humanly readable value.
// duration in milliseconds
long duration = ?????
long durationInSeconds = duration / 1000;
long durationInMinutes = duration / (60 * 1000);
long durationInHours = duration / (60 * 60 * 1000);
// careful - not always true!
long durationInDays = duration / (24 * 60 * 60 * 1000);
NOTE: The "daysBetween" calculation is potentially complicated by Daylight Time adjustments. The simple approach does not necessarily work exactly.

Capturing the difference between Actual and planned time

Hii...
I have created and released a production order which contains 25 operations and qty: 3 nos. I have done operation confirmation for 0010 operation as 2.5 hours (where as planned time is 1.5 hours). I would like to know how to get a report which can show the difference between actual & planned times.
And also I would like to know the operation time 1.5 hours which entered ny me was for operation of 1 number qty or its for 3 quantities.
Best regards,
Haneesh R

if you maintained in routing 1 qty = 1.5 hrs, when you create production order qty 3 = 3 * 1.5 hrs so total 4.5 hrs for that operation 0010 to completed

Just wondering what's the difference between using iChat and Face Time / Seems like face time is easier, especially wih my new 4s...?
So, if I wanna face time someone with a Mac (intel based) desktop, do they need face time app ?

What is the difference between start() and run()

Hi:
what is the difference between start() and the run()???
in my app, i have
Console.debug( "starting thread to listen for clients" );
_server = new Server( this );
_server.start();
_server extends Thread..
why everytime i use server.start(); my app will terminate on it is own, even though in my servr.run() method, i have a while loop
and if i call _server.run() explicitly in my code, that while loop will be in execution
can someone let me know??
thnx

what is the difference between start() and the
run()???start() is a method on Thread that tells it to start.
run() is a method in the object that the thread executes.
why everytime i use _server.start(); my app will
terminate on it is own, Err.... I'm not convinced this is true. It'll throw an IllegalThreadStateException, if you try to restart an existing thread.
If that's what you're saying.
even though in my _servr.run()
method, i have a while loopI don't see the connection. Are you saying that the while loop never terminates, and you don't see why the thread is terminating?
and if i call _server.run() explicitly in my code,
that while loop will be in executionIf you call server.run() explicitly, then run() will be executed in the same thread that you called it in.

Difference between a Change-run and Activate master data

Hi experts,
Could you tell me what is the difference between making a change-run on a masterdata (rsa1 --> Tools --> Apply Hierarchy/Attribute Change...), and making a right-click on this masterdata and click on "Activate master data" ?
The result seems to be the same, all rows in version M (Revised) are changed in version A (Active)...
Thanks for your help.
Tempka.

Hi
Change run will update the master data changes in Aggregates and update the object master data as well.
Activate master data will only activate the new records and it will not update the aggregates.
check out the below thread
Attribute Change Run VS Master data activation

Time running time of applications in windows??

How do I time the running time of applications in windows??
in linux its quite easy : time ./a.out
but how in windows??

You can use TimeIt.exe from MS's Windows Server 2003 Resource Kit Tools:
http://www.microsoft.com/downloads/deta … layLang=en
The whole kit has to be downloaded (~ 12 MB), but you can extract the rktools.exe file and then extract the rktools.msi file contained therein to get at the individual tools without having to install everything if you desire.
From the extracted readme file:
Timeit.exe
TimeIt is a command-line tool that records the time a specified command takes to run.
File Required
* Timeit.exe
TimeIt Syntax
timeit [-f FileName] [-a] [-c] [-i] [-d] [-s] [-t] [-k KeyName | -r KeyName] [-m Mask] [Command]
-f FileName
Specifies the name of the database file where TimeIt keeps a history of previous timings. The default file name is .\Timeit.dat
-k KeyName
Specifies the keyname to use for this timing run.
-r KeyName
Specifies the key name to remove from the database. If the key name is followed by a comma and a number, the slowest time (positive number) or the fastest time (negative number) for that key name will be removed.
-a
Specifies that TimeIt should display average of all timings for the specified key name.
-i
Ignores nonzero return codes from the program run by TimeIt.
-d
Shows detail for average.
-s
Suppresses systemwide counters.
-t
Specifies tabular output.
-c
Forces a re-sort of the database.
-m Mask
Specifies the processor affinity mask.
Command
Specifies the command to time.
Note
TimeIt accepts only parameters preceded with a dash (-).
Though I believe TimeIt is a good choice based on your post, alternatively you could install Cygwin or use the various timer modules / classes / functions available in a variety of different programming languages depending on which one(s) you may use.

Difference between extraction collective run and a V3 collective run

Hello Roberto.
As per your weblog can you elaborate on the difference between a Extraction collective run and a V3 collective run for Queued delta and V3 Update respecively,
Regards,
pravin

Hello Roberto,
Fine Roberto I have 3 more questions with regards to Queued delta-
1.     In case of Queued deltas how does the data come to the LBWQ ex. MCEX02 queue from the application technically when a transaction is posted in R/3.
2.     What role does the Function Module MCEX_UPDATE_02_QRFC play in getting the data in LBWQ.
3.     Does the extraction Queue read the update tables VBHDR,VBMOD eventually like the V3 collective run.

Pravin

Is there a difference between designated port and root port?

Hi,
I am reading up the Cisco press books and have some difficult understanding whether there is a difference in designated port and a root port?

Hi Shaik,
This explanation is too simple. What if u cascade some switches? Not all are directly connected to your root.
Next, bridge ID is only taken into consideration when determining which one will become the root. If u connect a switch to another with two links, the switch with the lower bridge-id becomes the root, but now u still don't know whitch port is the root port. U'r right when saying port cost is determined, but port cost is only the bandwith divided by a default constant (FE 100Mbit the constant is 10000000, i think), if its equal again u only have the port-ID as the last choice.
BUT only if the switch recieves on both Ports equal cost BPDU's from its root(refer to my first posting in this thread)!
U'r right.... a designated port is in forwarding state. It is forwarding the (lowest cost) BPDU's onto the connected segment. But if u have your lower end switch connected with two links to a non-root switch, u will encouter the same problem(s.o.).
I don't want to go against everyone here. But understanding STP is a nessassity in LAN Troubleshooting. So please be lenient against me.

Sebastian

Usage of line item dimension - design or run time?

Hi,
Can anyone please tell me at which stage a line item dimension is considered - at design time or after data load, once queries are run and performance degenerates?
I have read many posts and blogs about line item dimension and high cardinality, but I would require more information on when a line item dimension comes into play.
If we can decide at design time, then how is it done without data being loaded?
At which instances will the dimension table size exceed the fact table's size?
Please explain the above 2 points with a clear example, including the DIM ID and SID table access, and the ratio calculation for line item dimension consideration.
Thanks in advance.

Hello Aparajitha,
I agree with Suhas on point of consideration of LID . It would be good enough to consider a Dimension as LID in the Cube during design, it will be fruitful for the performance point of view. There is no point in saving the LID for future purpose if you have less than 13 Dimension in the Cube. It is going to save a extra join in connecting the relevant data.
If the total Dimension exceeds 13 or more (during design) , then you no option but include the related Char IO together in a one dimension.Here you cannot make a LID .
During the run phase, if the Dim table is more than 20 % of Fact Table, then for the sake of performance you have to go for the LID.In that case you will have the overhead of managing data (backup, delete & restore) .
On your specific questions :
"If we can decide at design time, then how is it done without data being loaded "
Technically same as you do during run-- Goto Dimension -- Right click --Properties -- and Check LID.
Logically -- Depending upon the Business meaning, which char has max unique values you can go with as LID.
"At which instances will the dimension table size exceed the fact table's size "
Frankly I haven't come across that.. ... Fact table is the center table and always will be the huge table in comparison to Dim table . Dim table cannot exceed the Fact Table ....!
Yes if the size of Dim Table is more than 20% of Fact table ( ratio of Dim Table to Fact Table) , then we have to select between the LID or High Cardanility.
Gurus..Please correct if anything is wrong ..!

YN
