Attribute Importance - Measure Influence of single classes

Hello,
I've been solving an Attribute Importance problem recently and identified the most influential factors. Now i want to find out which particular classes of this attribute have the strongest relation to the target.
If you take the affinity card problem from the Oracle Tutorials, I identified 'education' as the most influential attribute for example. But I still don't know which particular education has the strongest bond to the target, e.g. Master, Doctor, HS-Grad, etc.
I've already tried to create a Classification Build based on that single attribute, but when applying this model, the probability of the particular classes are always the same (or slightly differ on the third digit after the decimal point). Since the count of the particular classes ranges from 2 to 1655, I assume that I am doing something wrong and this is no coincidence (I already verified this with another attribute and the same result)
Is there any other way to find out the influence of the particular (categorical) classes used for the Attribute Importance?
Thanks in advance,
Dominik

Hi Dominik,
The particular integration of AI in the ODMr Column Filter node shows just column ranking. If you want to see more details on what models would consider important in ranking a column and its values, then build a GLM, SVM etc. model. You can look the coefficients of the model and see the level of significance given to categorical values of a column.
Thanks, Mark

How can I make server use single class loader for several applications

I have several web/ejb applications. These applications use some common libraries and should share instances of classes from those libraries.
But applications are being deployed independently thus packaging all them to EAR is not acceptable.
I suppose the problem is that each application uses separate class loader.
How can I make AS use single class loader for a set of applications?
Different applications depend on different libraries so I need a way that will not share library for all applications on the domain but only for some exact applications.
When I placed common jar to *%domain%/lib* - all works. But that jar is shared between all applications on the domain.
When I tried to place common jar to *%domain%/lib/applibs* and specified --libraries* attribute on deploying I got exception
java.lang.ClassCastException: a.FirstDao cannot be cast to a.FirstDaoHere http://download.oracle.com/docs/cd/E19879-01/820-4336/6nfqd2b1t/index.html I read:
If multiple applications or modules refer to the same libraries, classes in those libraries are automatically shared.
This can reduce the memory footprint and allow sharing of static information.Does it mean that classes should be able to be casted ?

You didn't specify which version of the application server you are using, but the config is similar as long as you know what to look for. Basically, you need to change the classloader delegation. Here's how it is done in 8.2

Is the whole jar loaded for a single class?

Hi,
Hopefully this is an easy yes/no question.
If my application makes reference to only a single class in a jar that has many other classes, does the entire jar (all the other classes) get loaded into memory?
If so, then it's worth it to break the jars up into only those classes I need (they're third party jars). Otherwise, I'll have to look for some other solution.
TIA.
Mike

No you don't.Yes he does - he was big enough to admit it - can't you?
import xyz.* doesn't "load everything in memory" as
schapel stated. You better read chapter 1 of your book
again (and again until it sinks in) before answering
advanced forum's questions.Perhaps you should reread schapel's post before making hot-headed replies to the advanced forum's questions. Besides, you must not read these forums too much because this topic comes up a lot.

Issue Importing measures against dimensions loaded via SSIS

Hi,
We are new to BPC and currently working in a test environment. We are having issues with importing measure data against dimensions that we are attempting to automate via SSIS. I will apologize in advance for the long post, but want to give as many details as possible.
Here is the scenario:
We installed BPC v. 5.1 SP1 on SQL Server 2005, but have since installed SP2 and SP3.
We created our own app set as a copy of AppShell. We added some user defined dimensions and created a custom application as a copy of Finance.
For initial testing, we loaded members into all dimensions via the Admin console and the Excel member sheets. We also used the Import function in data manager to upload measure data into our custom application.
We are now trying to automate the population of members for some of our dimensions (Entity and 4 user defined dimensions).
All of our data is mastered in SAP (we're on ERP 2005/ECC 6.0) with replications to our BI system (7.0). We are using custom ABAP programs to create flat files for 3 of the dimensions. For 2 dimensions, we are extracting from BI via Open hub.
We have created SSIS packages to load data from the files into the relevant mbr tables. We're taking things one step at a time and currently are processing the dimensions manually via the Admin Console - making sure that "Process members from member sheet" is unchecked.
In our first attempts at loading dimension data via the SSIS package, we tried loading only a subset of the member data (forgetting about the measure data that had previously been loaded). Because we were missing members in the load files for which measure data existed, we received data integrity errors upon processing the dimensions. Once we loaded the full member data, the dimensions processed successfully.
Our issue comes now when we're again importing measure data. Before starting to "automate" our dimensions, I had successfully loaded several months worth of measures. I had also tested clearing out one month of data. Now, I am trying to reload that month of measure data. I am using the same file as I had used previously, but the Import function is now rejecting all records. The dimension members it is rejecting are valid dimension members, but they are all from dimensions we are attempting to automate.
Has anyone encountered an issue like this before? Even if you haven't, do you have any thoughts on what our issue might be? Any help would be greatly appreciated!
Thanks!
Shannon

There actually could be a couple different things. The processing of the dimension could have encountered an error and therefore did not update the sql dim table association with the dimension. You should check to see if the dimDIMENSION sql table actual have any members in it and if the members you are trying to load to are there. If there were any errors in processing the mbr table the dim table will be empty.
Also the automated update could have added extra character to the member name such as a trailing space which would actually make the dimension member name different than what is in the membersheet.
In your automated dimension update, it would be a good idea to update the membersheet as well as the mbr sql table. Then you can process the dimension from the sheet in the admin tool to troubleshoot any errors in your memberset.

How to access an attribute(this is referencing to another class) in a class

Dear Gurus,
I have to read an attribute of a class and that attributes type another class.
I have intantiated the class and my question is how to read the attribute. I know I can not dirrectly read the attribute since this is another class. I think I have to first reference the attribute right? Please advise me.
My code looks like below:
data: lo_fpm                                 type ref to if_fpm.
data: lo_msg_mgr                        type ref to if_fpm_message_manager.
data: lo_component_manager    type ref to cl_fpm_component_manager.
lo_fpm = cl_fpm_factory=>get_instance( ).    " cl_fpm_factory is a class which has a static method get_instance
lo_msg_mgr = lo_fpm->mo_message_manager.
lo_component_manager = lo_fpm->mo_component_manager.
The above statement is giving syntax error. I do not know why.
The basic difference b/n the two methods is if_fpm~mo_message_manager    type ref to if_fpm_message_manager    and
mo_component_manager     type ref to cl_fpm_component_manager.
Any help would be appreciated.
Thanks,

Enabling log4j for a single class or package

hi all
If i use log4j for logging in my classes,
is there a way for enabling it just for a single class or a packages?
Considers that i use log4j.properties for configure it
Regards
Giovanni

Two things. Firstly, it's better to use private static final Object classLock = new Object();because that saves you worrying about whether any other code synchronises on it. Secondly, if you do decide to go for the delegation route then java.lang.reflect.Proxy may be a good way forward.

Hibernate: Mapping a 1:1 relation to a single class

Hy,
got the following situation:
Two Database-Tables:
1. loc_entry_history:
- "ehid": primary key, auto_increment, unique
- "time": Timestamp
- "views": int
2. loc_entry_history_info:
- "ehid": foreign key on "loc_entry_history.ehid", primary key, unique
- "title": String
- "plz": String
As you can see, this results in a 1:1 mapping between loc_entry_history and loc_entry_history_info. I now want to map these Data into ONE single class using Hibernate. I used the following Config:
<class name="de.dbruhn.framework.test.beans.History" table="loc_entry_history">
      <id name="id" column="ehid">
         <generator class="native" />
      </id>
      <property name="time" column="ehtime" type="timestamp" />
      <property name="ip" column="ehip" />
      <property name="views" column="ehviews" />
   </class>
   <class name="de.dbruhn.framework.test.beans.Info" table="loc_entry_info">
      <id name="id" column="ehid">
           <generator class="foreign">
               <param name="property">history</param>
           </generator>
       </id>
       <one-to-one name="history" constrained="true"/>
      <property name="title" column="eititle" />
      <property name="plz" column="eiplz" />
   </class> but this is not what I want:
I want the Data to be stored in a single Class, so one Class with the Name "history" where also the "title" and "plz" are stored.
How can I do this? I tried changing the "class name="[...].Info" into "class name="[...].History" but then the property "history" is missing. But I cant add the property history to the class, it would be a self-reference.
Thanks for any help

Thanks for your reply.
Because the data in loc_entry_info isn't always needed, so I put it into a second table to safe the table space!

Multiple Units of Measurements for a single item

Hi all,
How do I maintain multiple units of measurements for a single Item/ I have a scenario where purchase orders are being made for sand in Metric Tons, Tons, Kgs and Cubit Feets. Each measurement is being used at each construction site of the company but the item is single sand. One more problem is here with the material reconciliation of stock since it is maintained in different units of measurement and conversion from unit to other is problematic.
Thanks

Help with Error message in Flex 2.0 while trying to import from a library of classes

The following code is in a folder named saras. Inside saras
is a file named saras.as and a library of classes named
ASCB3Library. I downloaded this library after I purchased a book
named ActionScript 3.0 CookBook. I have tried every way I know for
a full week to instantiate the pen class from the library. I have
e-mail the book publishers and I understand that the author has
changed jobs --- I definately am not trying to make any bad
references --- I am simply asking for help --- there must be
someone out there with my same problem --- I am nottoo sharp but I
am not so obtuse as I seem to be making myself.
package {
import flash.display.Sprite;
import ASCB#Library.classes.ascb.drawing.Pen;
//import ascb.drawing.Pen;
public class saras extends Sprite
public function saras() {
var pen:Pen = new Pen(graphics);
pen.drawArc(100,100,50,80,20, true);
graphics.lineStyle(1,0,1);
graphics.lineTo(300,200);

As far as I know, iWork (without a s) was never depicted as opening _"all Excel documents"_ but as _"opening Exel documents"_ which means that it open _many of them but not all_ .
Is it surprising that it is unable to open documents created with an Excel version introduced after the Numbers creation ?
To get it able to open them, you will have to wait for the next major version.

Please clarify: can you add attributes to the Out of Box classes?

In this thread,
http://technet.oracle.com:89/ubb/Forum36/HTML/000116.html
It said, (March 21, 2001)
"You are not allowed to add attributes to the Out of Box classes that ship with IFS. You have to subclass the out-of-box attributes and define your custom attributes as extended attributes of your subclass. The add button is only active when the class you are viewing is not one of the out of box classes"
In the 1.9 documentation on page 179 I see
"Oracle 9iFS also allows you to add or modify attributes on content types after they
have been created.
Or, you may need to add custom attributes to the Document and Folder content types that come with Oracle 9iFS. You can add
attributes to a content type at any time"
Is this a new feature of 1.9?
Would a good workaround be to create a PropertyBundle for each Document and Folder? Would there be a big performance hit?
I dont want to create a new folder type and a new document type since I'm not sure how the rest of the system will use them.
Someone please respond, I've been trying to figure this out all day.
Thanks in advance
Mitch
null

In the isshell in ifs 1.1.9, I do a
ls -attrall
and I see "null" next to the property bundle. I assume this to mean that no property bundle has been created for this folder instance.
As for categories, 1.2 doc states.. "A folder, ... can be associated with zero,one or more categorys" I will have to create a new category for each file and or folder.
I really want to have additional attributes for each file.
I dont want to subclass folder because, if a user does a drag and drop in NTFS a folder will be created and not a MyFolder.
I have a kludge for now; I put a comma delimited list of items in description field.
Apparently this limitiation, is changed in 1.2. See above.
Thanks for your help. IFS is a really great product. Cant wait for 1.2 on NT.

Ok guys, being new to the Action scripting game, I am already finding myself with Errors. I have researched this for the last few days, and each time I come up with an answered solution, the solution is always the curly bracket. But for the life of me, I can not find a missing bracket!

Access to class attributs by coding in its mother class method definition

How can I retrieve information about a class attributs by coding?
And is it possible to access to the attributs of the Child class from the Mother class?

Hi,
a very easy way is to define an attribute TYPE REF TO DATA in the super class and write generic access methods which work with it by dereferencing it and assigning a field symbol. This might even save you the effort of creating a class hierarchy, because one class may be able to handle all the data objects whose types are only known at run-time.
In the below example, the only specific thing about the sub class is the constructor in which the data object is created and typed:

Problem with import statement for user created classe

I recently downloaded J2sdk1.4.0_03 before that I had jdk1.3 and never had this problem.All the files other than named package I import for my
application does not compile.But when I commented that out it work just fine.
any help is appreciated

thanks
It makes sense not to import non-packaged class.
My other problem is with JDBC ODBC.I have a Dell system with Windows XP.
I registered my User Data Source to ODBC with MS Text driver(.txt , csv).When the code reaches at the .executeUpdate(CREAT TABLE CUSTOMERS)
it throws an exception
sQLException 3:java.sql.SQLException: [Microsoft][ODBC Text Driver] Cannot modify the design of table 'CUSTOMERS'. It is in a read-only database.
Do I really need to change the attribues or some thing else.
How can I chane the attributes of the database.Never had problem with windows 98.

How to deploy a single class to the web portal?

EDIT: I've been able to create the deployment file. I found an older copy of NWDS and the old project folders are working perfectly again. I'll cross that bridge with the new version another time.
Firstly, sorry if this post is in the wrong section ... I looked around and couldn't find a section that I thought fitted.
A while back my company created a simple login module to similate a single sign on for our network. The module worked perfectly for a few months, then about a months ago it started rejecting logins for no apparent reason. I've asked all involved with the system and everyone claims that they haven't touched anything and that the problem must be within the Java class.
Due to recent workstation upgrades, I now have the latest version of NetWeaver Development Studio installed (SDN_Preview_SR_5_IDECE71). This new version does not like the old project that was created for this task, and I am struggling to create a new project which will do what I need.
Can someone point me to up-to-date documentation that explains how I can create a project which contains only a single java class that is to be deployed to a web portal? The class that is created extends the SAP class; com.sap.engine.interfaces.security.auth.AbstractLoginModule.
Please note that I have already look at some of the online documentation, for example: http://help.sap.com/saphelp_nw70ehp1/helpdata/en/e1/8e51341a06084de10000009b38f83b/frameset.htm
And that was of no help as it seems the documentation is no longer up-to-date with the current version ... or am I looking at the wrong documentation?
Another possibility is to install the older NetWeaver Development Studio, the problem here is I do not know where I can download a copy for Windows? I can only find the latest version for Windows online.
Thanks in advance for any and all assistance,

Hi Andreas,
You need to do the following:
- Upload the text file as a local configuration file in the "Local Content":
http://wikis.sun.com/display/OC2dot5/Uploading+a+Local+Configuration+File
- Create an OS Update Profile for the configuration file:
http://wikis.sun.com/display/OC2dot5/Creating+an+OS+Update+Profile
- Create a job and select the profile you have created as well as the servers you want to deploy the text file on:
