HashCode method return same value for different string?

Hello. I am finding hashCode method of string return same hashcode for many different string? It seem when string is long we get same value many times? What is solution? I am useing JDK 1.0.2. Thank you.

Hello. I am finding hashCode method of string return
same hashcode for many different string? There are about 4 billion possible hashcode values.
How many possible strings do you think there are?
Obviously many strings will have the same hashcode.
What is
solution?The solution is to not depend on hashcodes being unique.

Will a sequence return same value for two different sessions?

Is there a possibility that a sequence will return same value to two different sessions when it is referred exactly at the same instance of time?

@Justin... Thanks for your insight; indeed, we too feel this shouldn't ever happen and never heard of it either, but there it is. (No, we haven't logged a TAR yet -- whatever that is -- partly because it didn't occur to us and partly because we only recently came across the issue and sensibly want to do some testing before we cry foul.)
However, the code is pretty straight-forward, much like this (inside a FOR EACH ROW trigger body):
SELECT <seqname>.NEXTVAL INTO <keyvar> FROM DUAL;
INSERT INTO <tblname> (<keyfield>, <... some other fields>)
VALUES(<keyvar>, <... some other values> );
(where <tblname> is NOT the table on which the trigger is fired). This is the only place where the sequence is ever accessed. The sequence state is way below its limits (either MAXVALUE or <keyfield>/<keyvar> datatype size).
In this setup, end users sometimes got an out-of-the-blue SQL error to the effect that uniqueness constraint has been violated -- as I said, we used to have a unique index on <keyfield> -- which leads us to assume that the sequence generated a duplicate key (only way for the constraint to be violated, AFAIK). We released the constraint and indeed, using a simple SELECT <keyfield>, COUNT(*) FROM <tblname> GROUP BY <keyfield> HAVING COUNT(*)>1 got us some results.
Unfortunately, the <tblname> table gets regularly purged by a consumer process so it's hard to trace; now we created a logger trigger, on <tblname> this time, which tracks cases of duplicate <keyfield> inserts... We'll see how it goes.
@Laurent... winks at the CYCLE thing Our sequence is (needless to say) declared as NOCYCLE and the datatype is large enough to hold MAXVALUE.

SCCM 2012 Reporting Code Returns Same Value For Total Number Of Required Updates Per Computer

I'm trying to make a custom report in SCCM 2012 R2 with SQL 2012 since Microsoft took out the ability to list the number of updates needed per computer. This was in WSUS reporting but is not in SCCM reporting. I've made a custom report for this but can't
quite get it to work. The report runs but the same value for total number of updates needed shows up for every computer. I took a query from one report and am trying to get it to run inside the select statement from another report. Here is the code as it is
right now:
declare @CI_ID int; select @CI_ID=CI_ID from fn_rbac_ConfigurationItems(@UserSIDs) where CIType_ID=9 and CI_UniqueID=@AuthListID
          declare @StateID int
          select @StateID=StateID from fn_rbac_StateNames(@UserSIDs) sn where sn.StateName=@StateName and TopicType=300
          declare @RequiredUpdateCount int
          select @RequiredUpdateCount=Count(v_StateNames.Statename) from
v_StateNames,
v_Update_ComplianceStatusAll
Inner Join v_R_System On (v_R_System.ResourceID = v_Update_ComplianceStatusAll.ResourceID)
Inner Join v_UpdateInfo On (v_UpdateInfo.CI_ID = v_Update_ComplianceStatusAll.CI_ID)

v_StateNames.TopicType = 500 and
v_StateNames.StateID = v_Update_ComplianceStatusAll.Status and
v_StateNames.Statename = 'Update is required'

There's plenty wrong with it. It gives you no idea of how many patches each box needs. Then you have to click on each computer, click the sort arrow by the "required" column, and count the number needed. When you have hundreds of computers to work on this
is a big deal as it's very time consuming. What's great about the view in WSUS that had this is that it listed this for you and you could sort the required column. So if have most computers needing 2 patches, you can go find the one that needs 40 and 150 (to
over exaggerate) and put the time on them needed to see why they're so far behind. The WSUS format was quick, easy, and informative. SCCM makes getting this info a royal PITA which is why I'm (and many others) so royally peeved at MicroShaft for removing this
functionality, but that's what we've all come to expect from MicroShaft--just like when then took the nice colorful themes out of Office 2010 and replaced them in Office 2013 with just white, gray, and a darker gray. That's super boring and actually hurts
my eyes.

Qry return same value for a particular column for each row but not all time

hi,
We recently migrated to Oracle Database 10.2.0.3.0 from 9i. We were using a sql to populate a table and it had been running fine. After migration the same sql is fetching / population incorrect values, but not everytime. If we run the same sql again it gives a correct result.
Ex:
insert into a1 ( col1, col2, col3 )
select a.field1, b.field2, c.field
from tab1 a, tab2 b, tab3 c
where a.field = b.field
and b.field (+) = c.field
something like this. Let us assume it fetches 200 rows
But sometimes the col1 has the same value for all the 200 rows and col2, col3 has correct values. If we run the same sql next time, the col1 fetches the correct value and everything is correct.
Could someone help on the above issue.

I know it's difficult but can you put together a small test case for us to reproduce this behaviour? Did you contact Oracle Support?
Any special constructs used behind the scenes? Virtual private database? Views?Materialized Views? Anything else?

Same values for different address in BP

Hi Guys,
How to popup the standard (current) communication address details into new communication address details.
Scenario: The exited BP has one address and now he moved to another address, in that case we suppose to update or maintain his new address, am I right.
When I click on u2018createu2019 for new address on address tab in BP, the screen should be popup with current address communication (Telephone number, mobile number, fax and email) details into new address communication fields.
Ex : current address mobile number 9812345678, when you open new address.
The new address screen mobile number field would be display with same number 9812345678. Without manually work.
What is the solution for above business scenario in SAP 4.7

You cannot make the present communication address for a customer to come into the address screen of the new customer you are creating.
How does the system know that you are creating the master for the existing customer but with a new address!!!. It can be a new customer altogether.
Another important thing is, In this scenario, you should not create a new BP master. Then the customer number will be different and all the old history of the customer will be useless for you for any analytical purposes.
Just go to the customer master in change mode, and change the address. That should work well for ur need.

Random returning same values for all threads?

I "translated" an Applet example from a book to a MIDlet (as part of my learning process). However the MIDlet does not react as it should, and when the particles are all moving independently in the Applet, they are stuck together (as one) in the MIDlet.
So far, only one possibility was suggested to me: if the Random object are created one after the other, they could end up based on the same seed (which is the clock by default) and will generate the same numbers.
I tried to delay between the creation of the threads with no result. And the fact that the applet runs properly makes me wonder...
Does anyone have a clue?
In the MIDlet:
protected Thread makeThread(final Particle p) { // utility
 Runnable runloop = new Runnable() {
 public void run() {
 try {
 for(;;) {
 p.move();
 canvas.repaint();
 Thread.sleep(100); // 100msec is arbitrary
 catch (InterruptedException e) { return; }
 return new Thread(runloop);
}In the particle:
protected final Random rng = new Random();
public synchronized void move() {
 x += rng.nextInt(step) - (step/2);
 y += rng.nextInt(step) - (step/2);
 //returns exactly the same 10 times in a row
}

You might try justing just one static Random object.
Also note that als long as your using CLDC 1.0, you don't have any floating point support.

Two methods with same name but different return type?

Can I have two methods with same name but different return type in Java? I used to do this in C++ (method overloading or function overloading)
Here is my code:
import java.io.*;
public class Test{
public static void main(String ar[]){
try{
//I give an invalid file name to throw IO error.
File file = new File("c:/invalid file name becasue of spaces");
FileWriter writer = new FileWriter(file ,true);
writer.write("Test");
writer.close();
} catch (IOException IOe){
     System.out.println("Failure");
//call first method - displays stack trace on screen
     showerr(NPe);
//call second method - returns stack trace as string
        String msg = showerr(NPe);
        System.out.println(msg);
} // end of main
public static void showerr(Exception e){
     StringWriter sw = new StringWriter();
     PrintWriter pw = new PrintWriter(sw);
     e.printStackTrace(pw);
     try{
     pw.close();
     sw.close();
     catch (IOException IOe){
     IOe.printStackTrace();
     String stackTrace = sw.toString();
     System.out.println("Null Ptr\n" + stackTrace );
}//end of first showerr
public static String showerr(Exception e){
     StringWriter sw = new StringWriter();
     PrintWriter pw = new PrintWriter(sw);
     e.printStackTrace(pw);
     try{
     pw.close();
     sw.close();
     catch (IOException IOe){
     IOe.printStackTrace();
     return sw.toString();
}//end of second showerr
} // end of class
[\code]

Overloading is when you have multiple methods that have the same name and the same return type but take different parameters. See example
public class Overloader {
     public String buildError(Exception e){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( e.getClass().getName() )
               .append( " : " )
               .append( e.getMessage() ) ;
          return buffer.toString() ;
     public String buildError(String msg){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( msg ) ;
          return buffer.toString() ;
     public String buildErrors(int errCount){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( "There have been " )
               .append( errCount )
               .append( " errors encountered.") ;
          return buffer.toString() ;
}Make sense ???

SAP XI 3.0 Same source for different target in std Value mapping function

Hi,
We have replicated 4 value mapping entries from R3 to XI having the same Context , Agency , Schema and value for source, but each of the 4 values has the same Context and Agency but different Schema and Value respectively.
To illusstate :
Source                             |Target
Context Agency Schema    Value -----Context Agency   Schema     Value
CS1      AS1      SS1      1        CT1       AT1      ST1       A
CS1      AS1      SS1      1        CT1       AT1      ST2       A
CS1      AS1      SS1      1        CT1       AT1      ST3       B
This value mapping is not working and we always get the source value as the result.
We are wondering if the reason for this is that we use the same source for different targets. But we are not 100 % sure of it.
When I read the documentation on Value mapping or when we use the value mapping standard function in graphical mapping, we pass the context , agency and schema of the source and target respectively and the source value to get the target value, and this combination is always unique in our case as seen in the above example.
Has anyone faced this kind of an issue, if yes I would appreciate if anyone could help us resolve this problem.
Thanks in advance.
regards,
Advait

Hi Advait,
From the below what I understand is that you are not able to do value mapping for the follwoing
1     A
2     A
3     B
As value mapping allow one to one mapping only. Please do it like as mentioned below
1     1*A
2     2*A
3     3*B
Then in the graphical mapping of Integration Repository do the mapping for the same as shown below
source field > VALUEMAPPING> UDF--> TARGET Field
In UDF suppress the value of 1* , 2* , 3* which can be done as follows
create one UDF with one input field
//write the code as below to suppress the field
return input.substring(2);
Here the davantage of using 1* , 2* , 3* etc is that you have the option to use value mapping for 100 values which I think is not normally the case for any Interface.
If you have same source you can do the same thing for that.
Hope this helps you to resolve your query.

How to use different default parameter value for different report subscriptions

In ssrs is it possible to define different default parameter values for different subscriptions? In the following example I have a report which has two subscriptions with different start date and end date values:
Report name – Testsubscription.rdl
Subscription-1
Input parameter (default values):
start_date = first day of current Month
end_date = till date
Subscription-2
Input parameter (default values):
start_date = first day of current Quarter
end_date = till date
I know an alternative way of doing this would be to copy the rdl file with a different name but I am curious whether this can be done within a single report definition file. I am using SQL Server 2008 R2 Standard Edition.
Thanks!
spp

Hi sppdba,
As per my understanding, there is a report with two parameter: start_date and end_date, you want to configure subscription for the report, and set different default values for start date and end date. And you want to know if it is possible to achieve you
goal by using a single report definition file.
Since you are using SQL Server 2008 R2 Standard Edition, we need to achieve your goal by configuring two subscriptions for the report. For detail information, please refer to the following steps:
1. In design surface, right click start_date and open Parameter Properties dialog box.
2. In General pane, type Name and Prompt, set Data Type to Date/Time.
3. Click Available Values in left pane, select Specify Values.
4. Click Add button, in Label text box, type “First day of Current Month”, click (fx) button in Value section, then type the expression like below:
=DateSerial(Year(Now()), Month(Now()), 1)
5. Click Add button, in Label text box, type “First day of Current Quarter”, click (fx) button in Value section, then type the expression like below, then click OK.
=DateSerial(Year(Now()), (3*DatePart("q",Now()))-2, 1)
6. Right click end_date and open Parameter Properties dialog box.
7. In Available Values pane, select Specify Values.
8. Click Add button, in Label text box, type “Today”, click (fx) button in Value section, then type the expression =Today(), then click OK.
Now that the parameters are created, we need to configure subscription for the report. For detail information, please follow these steps:
1. Open Report Manager, and locate the report for which you want to create a new subscription.
2. Hover over the report, and click the drop-down arrow.
3. In the drop-down menu, click Manage. This opens the General properties page for the report.
4. Select the Subscriptions tab, and then click New Subscription.
5. Select the delivery extension and data source for the subscription.
6. Select a method of delivery, then choose report delivery options.
7. Specify conditions that cause the subscription to process and delivery to occur.
8. Set start_date to First day of Current Month, end_date to Today, then click OK.
9. Create a new subscription as step4 to 7, set start_date to First day of Current Quarter, end_date to Today, then click OK.
The following screenshots are for your reference:

Customisation for PO Release (different Values for different Doc Types)

Dear Experts,
I need to configure for PO release procedure where in the Characteristics would be Plant (2 Plants), Doc Type (3 types - Standard PO, Imports PO & Capital PO) and Value (2 stage release: 0-100000 & >100000 INR for Std PO, 0-200000 & >200000 INR for Imports PO and 0-300000 & >300000 INR for Capital PO).
Please let me know where I shoud define the different Values for different Docs for the Release procedure to work properly.
Or let me know the entire procedure for achieving the same.
Regards,
MNP

Hi MNP,
You have to create different CLASSes in IMG with the possible combination of different characteristics,
EX. CLASS EKKO11 - Plant A, Doc type- Std PO, Value- 0-100000 & >100000 INR
CLASS EKKO22- Plant A, Doc type- Import PO, Value- 0-200000 & >200000 INR
CLASS EKKO33- Plant A, Doc type- Capital PO, Value- 0-300000 & >300000 INR and same for other plant
then assign these classes to the respective Release group.

Insert into .. sql return incorrect value for 2 columns,sometime no value

Hello,
Oracle 10.2.0.3 , sol 10. (recently upgraded from oracle9i & sol8)
sql query is used to populate a table. sometimes it is populating same values for all the records in 2 columns. Sometimes not populating or partially populating 1 other column. other times its running fine.
SQL is not changed at all. When run again , it populates correctly.
any help is highly appreciatied.
--pooja

no ORA errors while execution. Its completing successfully.
and its an intermittent issue. when the SQL is run manually its gives perfect results. Rerunnign the entire process is also fine. Conclusivly, data & SQL has no problem.
its an insert into table <SQL>
SQL contains left outer join.
example:
Expected output:
1 john texas
2 smith MA
3 rob michigan
Actual Output
1 john texas
2 smith texas
3 rob texas

PPOME - Can't insert the SAME task for different organization unit

Hi all,
I have a doubt; in SAP 46C, it seems that is impossible to insert in PPOME, Detailed window, Tasks tab the same task for different organization unit. The only way to do this is in PP01 - General management, where you can explicitely create a [B-007] relations with the same "T" Object. Now, it is a little bit difficult for a user to switch from PPOME ad PP01 when defining new organizational structure.
The question: is there any way to insert the SAME task directly in PPOME, overwriting the standard behaviour of the system that by default create a new task for each new insertion?
Thanks all
Paolo

Hi Naveen
thank you for your prompt reply.
The issue that I want to solve is that some organization unit (not all) must be flagged for an external export to another system, depending on some characteristic of each org unit. I didn't find a similar attribute on standard field, so I thought to insert a common task to all the org units to export, so that this relation can serve as the missing attribute on org unit definition.
PP01 let me insert a task (type T, and not TS) on an org unit directly, so I want to know if I'm going to break some standard behaviour of SAP if I insert a task on OU.
Thank you
Paolo

Java returning incorrect values for width and height of a Tiff image

I have some TIFF images (sorry, I cannot post them b/c of there confidential nature) that are returning the incorrect values for the width and height. I am using Image.getWidth(null) and have tried the relevant methods from BufferedImage. When I open the same files in external viewers (Irfanview, MS Office Document Imaging) they look fine and report the "correct" dimensions. When I re-save the files, my code works fine. Obviously, there is something wrong with the files, but why would the Java code fail and not the external viewers? Is there some way I can detect file problems?

Figured it out. The files have a different vertical and horizontal resolutions. In this case the horizontal resolution is 200 DPI and the vertical is 100 DPI. The imgage width and height values are based on those resolution values. I wrote a section of code to take care of the problem (at least for TIFF 6.0)
 private void setPageSize(int pageNum) throws IOException
 IIOMetadata imageMetadata = _reader.getImageMetadata(pageNum);
 //Get the IFD (Image File Directory) which is the root of all the tags
 //for this image. From here we can get all the tags in the image.
 TIFFDirectory ifd = TIFFDirectory.createFromMetadata(imageMetadata);
 double xPixles = ifd.getTIFFField(256).getAsDouble(0);
 double yPixles = ifd.getTIFFField(257).getAsDouble(0);
 double xRes = ifd.getTIFFField(282).getAsDouble(0);
 double yres = ifd.getTIFFField(283).getAsDouble(0);
 int resUnits = ifd.getTIFFField(296).getAsInt(0);
 double imageWidth = xPixles / xRes;
 double imageHeight = yPixles / yres;
 //if units are in CM convert ot inches
 if (resUnits == 3)
 imageWidth = imageWidth * 0.3937;
 imageHeight = imageHeight * 0.3937;
 //convert to pixles in 72 DPI
 imageWidth = imageWidth * 72;
 imageHeight = imageHeight * 72;
 setImgWidth((int) Math.round(imageWidth));
 setImgHeight((int) Math.round(imageHeight));
 setImgAspectRatio(imageWidth / imageHeight);
 }

HashCode method return same value for different string?
