Can I use MD5 value for indexing files ?

I would like to know if MD5 value for each unqiue file is also unique. I am wonder if U can use MD5 value of a file for indexing. Any suggestion ??

I would like to know if MD5 value for each unqiue file
is also unique.No, since the number of MD5 hashes is less than the number of possible files. Of course, if you don't have many files the probability of clashes is pretty low. There's some theory about this which you'll find in algorithms textbooks where they talk about hash tables.
I am wonder if U can use MD5 value of
a file for indexing. Any suggestion ??Why? Don't you want your index to tell you something about the contents of the file?

Thanks

Because sync requires to use persistent storage locations. This is out of Adobe's control. It is entirely up to the hardware vendor how he anchors the drive/ volume and integrates it into the file and folder structure.

Can I use multiple values for a rollup key on the same Endeca record?

We have a business need to to aggregate our records using different criteria, based on user navigation. We are thinking of using a rollup key with multiple values to help with the aggregation, but we are running into some issues.
Here is a made-up xample of what we want to do: assume we have a group of products and these products can be organized into groups using parent-child relationships. We would like to create an aggregate record for each parent, and we want the aggregate record for each parent to include all the children for the parent. To achieve this, we use a field called "parent_rec_spec" that holds the parent record spec and we set the same value on the field for the parent and its children. When we do rollup using the parent_rec_spec as the rollup key, we are able to see one aggregate record for each parent (with its children).
The previous setup worked perfectly for us so far. But now we are getting a business requirement that allows children nodes to be linked to multiple parents at the same time. We were hoping of using another dimension to limit the records based on user roles/characteristics , so that only applicable parents/children are displayed (for example, we can use "market" as an additional filtering property, and we decide to show all parents/children for "North America", while hiding the parents/children for other markets).
This caused an odd behavior when children are linked to multiple parents. For example, assume that SKUs A and B were linked to parents in "North America" and "Europe" at the same time, and assume that the user chose the "North America" market. The navigation state would eliminate the parents/children that are no in North America, and will also cause the parents/children that are labeled for North America to show up and be aggregated correctly. This however will lead to the creation of additional aggregate records for the A and B using the parent_rec_spec values that would have linked them to the Europe parents (even though the parents are hidden away).
Here is an example index file that we used to load the test data:
Update||1
Market||North America
Record Type||Product
Name||Parent 1
rec_spec||P1
parent_rec_spec||P1
EOR
Update||1
Market||Europe
Record Type||Product
Name||Parent 2
rec_spec||P2
parent_rec_spec||P2
EOR
Update||1
Market||North America
Record Type||Product
Name||Child A
rec_spec||A
parent_rec_spec||P1
EOR
Update||1
Market||North America
Market||Europe
Record Type||Product
Name||Child B
rec_spec||B
parent_rec_spec||P1
parent_rec_spec||P2
EOR
Update||1
Market||North America
Market||Europe
Record Type||Product
Name||Child C
rec_spec||C
parent_rec_spec||P1
parent_rec_spec||P2
EOR
Update||1
Market||Europe
Record Type||Product
Name||Child D
rec_spec||D
parent_rec_spec||P2
EOR
In this setup, we have parent P1 marked for North America with children A, B and C, and parent P2 marked for Europe with B, C and D as children. When we use North America as a filter in the navigation state, and parent_rec_spec as the rollup key, then we will see an aggregate record for P1, A, B and C. But we will also see an aggregate record for B and C by itself (presumably because of the other parent_rec_spec value on these records).
The actual data that we are testing with is more complicated, but the end result is similar. We also noticed that the additional aggregate records would not be created always, depending on the ordering of the records.
The question that I need help with is this: is there a way to fine tune the rollup logic so that it can only include certain records (in the example above, we can change the rec_spec from PA and PB to PA_North_America and PB_Europe and then we would be interested in rolling up using values that end with NorthAmerica).
By the way, we considered using separate rollup keys for each context (like parent_rec_spec_north_america and parent_rec_spec_europe), but the number of contexts is dynamic, and might grow large. So it is not easy for us to create the additional properties on the fly, and we are concerned about the possible large number of dimensions.

Thanks for you reply.
But actually I don't want to show the \ (backslashes) to the user in my text box.
Ok let me elaborate this problem little more.
I want to show my text box as it is in normal editors e.g. In Matlab editor. There is a text box and on left side the gray bar shows the line numbers corresponding to the text. Further more i want that the user should be able to click on any line number to mark specific line as breakpoint (red circle or any graphical indication for mark).

How can I use jbo:InputSelect for a char type filed?

How can I use <jbo:InputSelect for a char type filed?
I have two tables. One is room (primary key is room(type is char)), another table is responsibility (foreign ker is room(type is char)). Both tables have same length for room column.
There is a problem:
If I use (in the "DataEditComponent.jsp" file)
<jbo:InputSelect multiple="false" datasource="dsEdit" displaydatasource="roomData" displaydataitem="ROOM" displayvaluedataitem="ROOM" ></jbo:InputSelect>
to get the room input for responsibility from combobox(Datasource roomData is from room table). In the form the room field cannot bind the data in combobox, alway select the first item. And if I select one item and click the update button.There is an error message:
Error Message: JBO-27010: Attribute set with value H409 for Room in Responsibility has invalid precision/scale
I found If I changed the field type from char to varchar2 in database also change the entity objects, it works well. I wonder if there are any diffrence using <jbo:InputSelect tag in char and varchar2 type. How can I use <jbo:InputSelect for a char type filed as i don't want to change my datatype in database at this stage.
I try this in JDeveloper 9.03, 9.034, 9.04. The result is the same.

If I were in your shoes, here's how I would do it:
<%-- Assuming you have dsRoom and dsResponsibility --%>
<%-- Select is an HTML tag --%>
<select name="ROOM" size="1">
<% char roomID =""; // Init your character var
// Open a rowsetIterator to get the records and add them to the LOV
<jbo:RowsetIterate datasource="dsResponsibility" changecurrentrow="true" >
<% roomID = (char)dsResponsibility.getRowSet().getCurrentRow().getAttribute("ROOM"); // Grab the char value
// add the value to the LOV
%>
<option value="<%=roomID%>"><%=roomID%></option>
</jbo:RowsetIterate>
</select>
If you are using this as part of an edit page you may want to utilize the "selected" option of the <option> tag. In one instance I am doing this on an edit page because the use may open an existing record. If I don't account for it, then it will change the DB to contain the first value from the list! You can do a simple check like:
//Set the current record's char
char curRecord = (char)rowEdit.getAttribute("ROOM");
// inside the iterate:
if (curRecord == roomID) {
<option value="<%=roomID%>" selected><%=roomID%></option>
} else {
<option value="<%=roomID%>" ><%=roomID%></option>
Hope that helps!

Dear Friend,
Here when you have the callableSattement as ?=proc(?), the first ? is an output parameter. So you should register it as out parameter using registeroutparameter.
Then you can get the value from the outparameter using callablestatement.getXXX().
Try that way.

Can i use create function for MSSql scalar and table valude function.

Hi,

2) How many type of user defined function are there in oracle 11g express?
3) And can i reture any "type" form user defined function?

Q1)That means even if i return predefined types like integer, varchar2 then also PGA is used ?The data type does not determine where the variable is stored. A string (called a varchar2 in Oracle) can be stored in stack space, heap space, on disk, in a memory mapped file, in a shared memory, in an atom table, etc.
It is the who and what is defining and using that string, that determines where and how it is stored.
The Oracle sever supports 2 languages in PL/SQL. The PL (Programming Logic) language is a procedural/declarative language. It is NOT SQL. SQL is integrated with it. The PL/SQL engine uses private process memory (PGA). So PL/SQL variables exist in the PGA (but there are exceptions such as LOBs).
Q2) So please suggest me solution in oracle.Sounds to me you are looking at how to implement a T-SQL style function as an Oracle function, and once implemented, do joins on the function.
Do not use PL/SQL in SQL in place of a SQL select. It is not T-SQL.
One cannot use PL/SQL to create functions along the style of T-SQL, where the function executes a SQL using some conditional logic, and then return as if the function was a native SQL select.
T-SQL is an extension to the SQL language - making it a hybrid and very impure language implementation. PL is based on ADA - part of the Pascal family of languages. The E-SQL (embedded SQL) approach used in languages like C/C++, Cobol and Ada, has been transparently done in PL/SQL. You can write and mix PL code and variables with SQL code. And the PL/SQL engine figures out how to make the call from the PL/SQL engine to the SQL engine.
But PL/SQL is not "part" of the SQL language and does not "extend" the SQL language in a T-SQL fashion.
So you need to check your SQL-Server preconcepts in at the door, as they are not only irrelevant in Oracle, they are WRONG in Oracle.
The correct way in Oracle, in a nutshell - Use the SQL language to do data processing. Use PL/SQL to manage conditional process flow and the handling of errors.

Can I use servlet as my welcome file

How can I use servlet as my welcome file? I know how to use jsp or html pages as my welcome file but that doesn't work for servlets. I modified my web.xml for making jsps and html as my welcome pages but that <welcome-file-list> tag is not working for servlets.

This was a bug that occured in older Tomcat programs, not sure if it still occurs or not.
Basically, when this happens, you have to have a physical file with the welcome file name. So you would have to create a file named index.do in each of your directories you wanted the welcome to work for. The index.do wouldn't have to actually do anything. It just had to exist. Then when the URL was used to create content, the servlet would be called to create that content.

HT3354 how can i use one table for reference to another

how can i use a table for a referance to another eg when i type a word in a cell, i will like it to match the word with another table then return the information in the cell i am using

you can use vlookup() (or any of the lookup family of functions) to locate an item based on a key value:
Here is an example of something you can do with two tables:
The table on the right is title "Data" and stores a list of names with age and favorite color.
The table on the left uses the value in the first column to lookup up information in the table Data
in the table on the left:
B2=IFERROR(A2&" is " & VLOOKUP(A2, Data :: A:D, 2, 0)&" years old and likes the color "& VLOOKUP(A2, Data :: A:D, 3, 0), "NOT FOUND")
I know this look complicated. so I'll break it up into smalled pieces:
first the "&" is called the concatenate operator and joins two strings. like this:
a string is a set of characters between double quotes.
so "string 1" & "string 2" becomes "string 1string2" or "Sam " & "Jones" becomes "Sam Jones"
you can use cell references instead of strings directly in which case the concatenation is performed on the contents of the cells.
so if cell A1 contains "Hi " and the cell A2 contains "There" then A1 & A2 will result in "Hi There"
so you could add the formula
A3=A1 & A2
this is short hand for select cell A3 then type everything including the A3 so that A3 contains "=A1 & A2" (omit the double quote)
OK. So the formula I provided concatenates several items together:
it concatenates A2, then the string " is " then a formula, then the string " years old and likes the color " then a formula
the two formulas (highlighted in blue) perform a lookup of the value in cell A2 in columns A thru D of the table named "Data". If if finds the value in cell A2 in the first column of the lookup range in the table Data (column A) then it returns the value from the same row but in the second or third column.
all that is in a function calld iserror() to trap the condition where the calue you enter in A2 does not exist in the table Data:

Can I use the value range as F4 ValueHelp in WebUI?

I have a Z-field in CustomerH. Its datatype has a domain with a fixed value range attached.
I show this field in the header of a sales order but the value help does not show up automatically.
My question is: Can I use this value range as input for the value help or do I have to code a "real" value help and attach it via the V-Getter?
Thanks.

How can I use a Value at several different places without using a long wire?

too much wire alway make program into mess.So can I use the Value in labview like using it in C.
I have try the "Local Value",but it don't work well as a Cluster. For example, I can't connect it with "Unbundle By Name" and other Cluster Tools.

Overuse of local variables is probably worse than the "mess" created by long wires. It increases memory usage, violates data flow, and increases probability of race conditions. A better solution to long wires is to make the diagram smaller by using subVIs. There's been a lot of discussion here and in the various LabVIEW style guides about avoiding local and global variables. I use them seldom and only then when I doing some complicated user interface.

Hi, how can i break the value for a row and column once i have converted the image to the array???????

Hi, I would like to know how can i break the value for a row and column once i have converted the image to the array. I wanted to make some modification on the element of the array at a certain position. how can i do that?
At the moment (as per attachhment), the value of the new row and column will be inserted by the user. But now, I want to do some coding that will automatically insert the new value of the row and the column ( I will use the formula node for the programming). But the question now, I don't know how to split the row and the column. Is it the value of i in the 'for loop'? I've tried to link the 'i' to the input of the 'replace subset array icon' , but i'm unable to do it as i got some error.
Please help me!
For your information, I'm using LABView 7.0.

Hi,
Thanks for your reply.Sorry for the confusion.
I manage to change the array element by changing the row and column value. But, what i want is to allow the program to change the array element at a specified row and column value, where the new value is generated automatically by the program.
Atatched is the diagram. I've detailed out the program . you may refer to the comments in the formula node. There are 2 arrays going into the loop. If a >3, then the program will switch to b, where if b =0, then the program will check on the value of the next element which is in the same row with b but in the next column. But if b =45, another set of checking will be done at a dufferent value of row and column.
I hope that I have made the problem clear. Sorry if it is still confusing.
Hope you can help me. Thank you!!!!

Can I use "dvt" function for customizing the chart format in OBIEE 11g?

Hi,
".pcxml" file cannot be found in OBIEE11g. However, can I use "dvt" function for customization? If yes, how?
Reference for dvt function:
http://docs.oracle.com/cd/E23943_01/apirefs.1111/e12418/tagdoc/dvt_pieGraph.html

Hello,
I know it's possible, because i already found some blogs about changing the chart colors and turning off the animated graphs.
<Graph visualEffects="NONE" animationDuration="0">
But we want to alter more chart options, like make a bar chart default stacked. In 10G this was possible. I think this is also
possible in 11G through the dvt-graph-skin.xml, but what i want to know is, is there a document that explains which tags you could use in this file.
It would be great to get some help on this.
