Loading the rules from database?

Hi
I understand that I can load the rule base from the file system using the following code:
EngineConfiguration configuration = new EngineConfiguration();
configuration.setRulebaseDirectory(rulebasePath);
InterviewEngine engine = InterviewEngineFactory.createInstance(configuration);
But, in my case I want to store and load the rule base from the database. How can I achieve this?

GBTW,
I assume you want Web Determinations to load rulebases from a Database. The explanation of how to do this can be found in: Oracle Policy Automation Developer Help in the section Create a Rulebase Service
A tutorial can be found by searching for: DerbyRulebaseService in the Developer help.

Pre-loading the Cache from Database during application start-up

We are using Spring, Hibernate, Oracle Coherence 3.5.2 Weblogic Webservices
Our requirement is to pre-load the cache during the application start-up most probably during Authentication/Authorization Service is invoked.
We plan to load the data for other services from database into Coherence cache so that whenever user access that particular service he ends up hitting the Cache instead of database.
We would greatly appreciate sample code snippets on how to write CacheInitializerBean with marker to demonstrate the state of cache.

Hi Rob,
Thanks for pointing to the article: Pre-Loading the Cache
In fact i already looked at that article before posting. It just mentions how to load the data from database into Cache.
What i am looking for is how to make this happen during application start-up. This is my first hurdle.
The second one is as mentioned in the article http://coherence.oracle.com/display/COH35UG/Pre-Loading+the+Cache
i wrote following code which never gets populated into cache. Not sure whats going wrong even though i see Hibernate loadAll() method loading all the objects in the console
public   void populateCache() throws SQLException
    Map<Long, Object> buffer = new HashMap<Long, Object>();
    int count = 0;
     List<Contract> contractList = this.getHibernateTemplate().loadAll(Contract.class);
     log.debug("contractList size="+contractList.size());
     for(Contract contract : contractList)
         Long key   = new Long(contract.getId());
         Object value = contract;
         buffer.put(key, value);
         // this loads 1000 items at a time into the cache
         if ((count++ % 1000) == 0)
              contractCache.putAll(buffer);
             buffer.clear();
     if (!buffer.isEmpty())
          contractCache.putAll(buffer);
    }We would greatly appreciate your time in helping us resolving two hurdle blocks.

Error while loading the data from excel to database.

Hi,
I am using PL/SQL developer to load the data from excel to database. I will set the data source in the control panel and will proceed through ODBC importer in pl/sql developer to import the data.
What exactly the error is when i click the filename to view the result preview it shows an error as:
The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data.
Kindly help with solution.
Thanks/Regards
Sakthivarman J.

Hello;
That error message comes from Microsoft, so something in you Excel sheet is the cause.
Its a pain but I would check properties of each column in case Excel decided to add something, a comma for example.
Do you have a column over 255 characters? Look there first. If any length is greater than 255 it will crash and burn.
Or convert it to a CSV and create an external table.
Best Regards

Might also throw an 3163 as an error where you cannot see it.

I have created the following table to store the images
create table DEMO
ID INTEGER not null,
THEBLOB BLOB
And I also uploaded the Images. Now I am try to get a image from the table using the following procedure .But I am getting the error message line 25( htp.prn( utl_raw.cast_to_varchar2( l_raw ) );) .at it throws the following error messages
ORA-06502: PL/SQL : numeric or value error:Character string buffer too small

SYS.htp.prn procedure of the following line of code
if (rows_in < pack_after) then
while ((len - loc) >= HTBUF_LEN)
loop
rows_in := rows_in + 1;
htbuf(rows_in) := substr(cbuf, loc + 1, HTBUF_LEN);
loc := loc + HTBUF_LEN;
end loop;
if (loc < len)
then
rows_in := rows_in + 1;
htbuf(rows_in) := substr(cbuf, loc + 1);
end if;
return;
end if;
Its a system procedure. I don't no how to proceed .. I am really stucked on this....is their any other method to take picture from the database and displayed in the web page.....???? any idea..../suggesstion??
Thanks for your help!!!.

Load the data from a transparent customised table in BW to an ODS

Hi there,
How can you load the data from a transparent customised table created in BW to an ODS.
Many thanks.
Sarah

Hi,
just create a generic datasource in rso2 for that table, replicate the datasource for source system 'myself', create a infosource and assign the new datasource to that infosource. Create a update rule from infosource to ods, create a infopackage and load the data.

Error while loading the data from text file

Hi,
I got an error " Data Value Encountered before all Dimensions selected" while loading the data from the text file.
Can any one please suggest me the solution.

Possible Solutions
Make sure that the data source is valid.
Is a member from each dimension specified correctly in the data source or rules file?
Is the numeric data field at the end of the record? If not, move the numeric data field in the data source or move the numeric data field in the rules file.
Are all members that might contain numbers (such as "100") enclosed in quotation marks in the data source?
If you are using a header, is the header set up correctly? Remember that you can add missing dimension names to the header.
Does the data source contain extra spaces or tabs?
Has the updated outline been saved?

Error while loading the data from ODS to InfoCube

hai
Im trying to load the data from ODS to InfoCube for particular year .
But it says that there is a source system problem .
why it is like that .
pls tell me
i ll assing the points
rizwan

Hi Rizwan,
you didn't mention the error message in details. there could be a few places to be checked:
- check if BW itself source system is active and in tact and reactivate if necessary
- check if update rule is active and reactivate if necessary
- check if ODS is active and reactivate if necessary

Error in loading the data from flatfile

Hello All,
when am loading the data from flat file iam getting error "ERROR4 WHEN LOADING THE EXTERNAL DATA" is it because of mapping in the transferrules or error in the flat file.
Points will be assigned to all helpful answer.
Thanks & Regards
Priya

Hii Priya,
The reasons may be the file is open, the format/flatfile structure is not correct, the mapping/transfer structure may not be correct, presence of invalid characters/data inconsistency in the file, etc.
Check if the flatfile in .CSV format.
You have to save it in .CSV format for the flatfile loading to work.
Also check the connection issues between source system and BW or sometimes may be due to inactive update rules.
Refer
error 1
Find out the actual reason and let us know.
Hope this helps.

Problem with displaying the data from Database on swf file.

Hi ,
I am new to flash.Thanks in Advance Please help me....
Actually my requirement is my application consists a button(submit_Btn) when we click on the button(submit_Btn), each time it must to database(through servlet) and brings the data from database and places it on the flash swf file.Here my problem is for the first time when we click on the button it goes to database and place the data(which was returned from database) on the swf file.Next when we click on the button for the second time(or anytime) it is not going and bringing the new data from database(if some data is modified in database or not),Infact it is showing the old data(the data that was collected from previous ClickListener) only on the swf file and it is also not showing any complile time or run time error.
my Code looks like this:
submit_Btn.addEventListener(MouseEvent.CLICK,onCheck2);
function onCheck2(evnt:MouseEvent):void {
var xmlLoader:URLLoader = new URLLoader();
    var xmlurl:String = "http://localhost:8888/xmlServlet";
    var xmlrequest:URLRequest = new URLRequest(xmlurl);
xmlLoader.dataFormat = URLLoaderDataFormat.TEXT;
xmlLoader.addEventListener(Event.COMPLETE, xmlcompleteHandler);
xmlLoader.load(xmlrequest);
function xmlcompleteHandler(event:Event):void {
    var loader:URLLoader = URLLoader(event.target);
    var succData:String=loader.data;
        var xmlData:XML = new XML();
        var xmlList:XMLList;
        xmlData = XML(loader.data);
        xmlList = xmlData.children();
        for (var i=0; i<xmlList.length(); i++) {
            for (var n=0; n<xmlData.UserHumanap[i].HumanapDot.length(); n++) {
                    var x_coordinate:Number = xmlData.UserHumanap[i].HumanapDot[n].@x;
                    var y_coordinate:Number = xmlData.UserHumanap[i].HumanapDot[n].@y;
                    var point2:Point = new Point(x_coordinate,y_coordinate);
                    var circle:Sprite = new Sprite();
                    circle.graphics.beginFill(0x00ff00);
                    circle.graphics.drawCircle(point2.x,point2.y,3);   //Placing the data as dots on the swf file
Thanks in Advance.......Please Help me..........
its Urgent..........
Thanks,
Swarthi

Checkout following line in your code
var xmlurl:String = "http://localhost:8888/xmlServlet";
now change it to
var xmlurl:String = "http://localhost:8888/xmlServlet?random="+String(MAth.random());
I think you will get the point now

Unable to load the data from PSA to INFOCUBE

Hi BI Experts, good afternoon.
    I am loading 3 years data( Full load ) from R/3 to Infocube.
   So loaded the data by monthwise. So i created 36 info packages.
Everything is fine. But i got a error in Jan 2005 and Mar 2005. It is the same error in both months. That is Caller 01and caller 02 errors( Means invalid characteristics are there PSA data )
So i deleted both PSA and Data target Requests and again i loaded the data only to PSA.
Here i got data in PSA without fail.
Then i tried to load the data from PSA to Infocube MANUALLY.
But its not happening.
One message came this
       SID 60,758 is smaller than the compress SID of cube ZIC_C03; no        request booking.
   Please give me the solution how to solve this problem.
Thanks & Regards

Hi Teja,
   Thanks for the good response.
How can i check whether it is already compressed or not?
Pls give me the reply.

Actually i want to get the data from database randomly, i dont have problem either in database connection and generating random number,its working fine. but when i have to get the data from database with generated random no using absolute function , i am getting an exception
eg : rs.absolute(2);
i could not move to the second row of my result set.
not only absolute function whatever the function i am using except next method, getting exception.
my code :

I have multiple Apple IDs. Is there a way for me to merge them into a single Apple ID?
Apple IDs cannot be merged. You should use your preferred Apple ID from now on, but you can still access your purchased items such as music, movies, or software using your other Apple IDs.

You mean when you click on the hyperlink you want that row to disappear from the page, but not delete the row from the database until a commit/submit button is pressed?
Personally, I think I'd prefer that you have a delete checkbox next to every row and NOT remove them from the display if I was a user. You give your users a chance to change their mind about their choice, and when they're done they can see exactly which rows will be deleted before they commit.
You know your problem, of course, so you might have a good reason for designing it this way. But I'd prefer not removing them from the display. JMO - MOD
