Expression Builder performance

Is there anything that can be done about the Expression Builder performance? Whenever I need to make a change to an XPath expression I've got to wait 2-3 minutes for JDev to respond. Very irritating. I'm using 10.1.3.3.0 (Build 070615.0525)

If you look at this document :
http://download.oracle.com/docs/cd/B31017_01/integrate.1013/b28981/appx_deploydesc.htm
and search for :
xpathValidation
"xpathValidation Default value is True. If set to False, the compiler does not validate the XPath queries."
maybe this is what you need.

XPath Expression Builder Performance after Oracle FMW PS4 Upgrade

Hi,
Is there anyone out there on OFMW PS4 and facing performance issues with the BPEL Assign 'XPath Expression Builder'. We have a scenario where the BPEL process has to reference many schemas (arnd. 50+) from referenced Partner Link WSDLs and its own composite. The Expression Builder seems to be very very slow (takes minutes to load) as compared PS2 (only seconds).
Are we alone on this one / anyone has any experience/fix/workaround?
BTW,
We've unchecked the "Validate" check box from SOA Preferences, still no luck.

Compare only DATE portion of a datetime field in Expression builder

Hi! All,
This may be a simple question, but I couldn't find the answer. I have a query where I want to say :
Expression exp = exp1.get("startDateTime").equal(pDate);
here pDate is a java.util.Date class with a time stamp.
I wish to basically compare just the DATE portion of the value stored in the data base with only the DATE portion of "pDate" and ignore the time component.
How do I do this in expression builder?
By the way we are on Toplink 9.0.4.5
Thanks

There are a couple of ways to accomplish this. You could use between(beginningOfDay,endOfDay) where beginning of day is 12:00:00am on the date specified in pDate and end of day is 11:59:59pm on pDate. Or you could consider using a combination of dateName(), datePart(), and/or truncateDate() expressions to compare at the day, month, year level. I am not sure which would give you better performance, so you might need to do some testing to verify.
In the first case, create beginningOfDay and endOfDay based upon the date housed in pDate. Then:
Expression selectionCriteria = exp1.get("startDateTime").between(beginningOfDay,endOfDay);
In the second case, there would be a little more code to write:
Expression startDateTimeExp = exp1.get("startDateTime");
Expression dayExp = startDateTimeExp.datePart("day");
Expression monthExp = startDateTimeExp.datePart("month");
Expression yearExp = startDateTimeExp.datePart("year");
int desiredDay = get day of month from pDate;
int desiredMonth = get month of year from pDate;
int desiredYear = get year from pDate;
Expression selectionCriteria = dayExp.equal(desiredDay).and(monthExp.equal(desiredMonth)).and(yearExp.equal(desiredYear));
Check out the TopLink API docs on the Expression class for more details on what these Expression building methods do : http://download-west.oracle.com/docs/cd/B10464_05/web.904/b10491/index.html
Hope that helps,

DIfference b/w expression builder logical column and derived logical column

Hi Experts,
Can anyone tellme the difference between expression builder (when we double click the logical column) of derived logical column and expression builder of logical column( we see this in column mapping of LTS) ??
Thanks in advance.

Hi,
Formula given in the "expression builder of logical column( we see this in column mapping of LTS)" is performed on the physical layer of the RPD. I guess it is calculated in the Physical Query which is good for performance.
Formula in the expression builder of derived column is calculated in the BMM layer i.e in the logical query.

Amrutha.

Expression Builder In Oracle Rule Authoe

Hi,
I am using expression builder for making this kind of expression:
x = y* (new Double(.02))
where x and y are Double.
after inserting the variables and operator, validation always fails showing the following message:
Cannot perform operation. 'RUL-01726: Data type operator for *, at position 10: java.lang.Double * java.lang.Double '
Please tell me where i am going wrong. It's very urgent.

Thanks for the reply Phil.
I think that when I am updating datamodel, it is updating every thing in data model i.e. variables, constraints, functions, facts everything.
Do you have knowledge of any method in the API which updates only variables??
Also, i followed a different methodolgy be using RuleSession. have a look at code snippet:
String rsrl ;
* Double testValue = 6000.0;*
* Double discount = new Double(0);*
* try {*
* rsrl = dict.ruleSetRL( ruleSetName );*
* String dmrl = dict.dataModelRL();*
* RuleSession session = new RuleSession();*
* session.executeRuleset( dmrl );*
* session.executeRuleset( rsrl );*
* discount = (Double)session.callFunctionWithArgument("DM.calculateDiscount",testValue);*
* System.out.println(" Discount "+discount);*
* } catch (Exception e) {*
* e.printStackTrace();*
Here instead of updating dataModel i am executing ruleSet using session and callingFunction to calculate discount.
Now if disocunt is populated independent of any other vairable (e.g. discount = 10.0d instead of discount = 10.0*salesValue)
then it should work. But if discount is dependent on some variable (which has to be global Variable) then it would not populate it.
This is what i have thought.
But the above code snippets always give following exception :
oracle.rules.rl.exceptions.InvocationException: wrong argument type in function or method invocation
even when function takes arguments in my dictionary.
Your help is much awaited!! Thanks in advance.

Expression Builder: convert string to number

Hi all,
I'm having trouble building a field validation rule for bank account numbers.
The numbers have 12 positions, so I cannot use a string or text number.
The validation rule to be implemented is that the last two digits are calculated based on the first 10 (modulo 97).
However, when I use the Mid function to pick the first characters, I am unable to do any calculations on it. Apparently, the string to number conversion doesn't work (it should work when I read the manual, as it says that when using an operator between two data types, the second type is converted to the first (cf. example of 1234+abcd (should result in 1234 as to the manual))). So I tried '1*Mid(...)' or '0+Mid(...)'. Syntactically the expression builder accepts it and I can save it. BUT when I change the particular value on the screen, it gives me an SSO error (not the Field Validation error message I entered).
Why isn't there simply a function ToNumber (like ToChar)????? How could I workaround this?
Any input very welcome!
Frederik

Apparently, I was a bit confused when typing the first sentence, it should be:
The numbers have 12 positions, so I cannot use an integer or number data type, but have to use String.

Using Decode in Expression Builder...

Hi everybody,
I want to use the DECODE function of SQL in an Expression Builder....
Of course this function does not exist in any of the transformation categories(arithmetic,character,e.t.c.) in the expression builder.
I have read in the OWB on-line help that in the Expression Builder there should be an 'Others' drop - down list in order to select any of the available SQL clauses - one of them is 'decode'...
The problem is that this drop - down list in the Expression Builder is disabled.....
How can I use this function anyway..????
Instead of using ... in the Expression Builder...
decode(<column_name>,'1','val_one','2','val_two') what can I use to do the same....???
As regards the problem that the drop-down list is disabled , what may be the cause..???
I use Microsoft XP machine , Oracle 10g (v.10.2) and OWB v.10.1.0.4
The documentation says....
"This allows you to deploy the DECODE functionality in all operating modes (setbased, rowbased, etc.) and transparently across Oracle database releases (8.1, 9.0 and 9.2)."
The above means that the cause is the incompatibility..????
Thanks , a lot
Simon

I am using OWB 9.2.0.8 and I can't reproduce the problem you are having with 10.1, but did you try just typing it into the expression?
Or, better yet, use CASE. The syntax is easier to read. I think OWB translates DECODEs to CASE when the SQL is generated.
(Case <column_name>
When '1' Then 'val_one'
When '2' Then 'val_two'
End)

How to use SQL OVER and PARTITION BY in OBIEE Expression Builder??

Hi there,
I want to create a new logical coulmn with the following SQL query.
SUM(Inventory Detail.Qty) OVER(PARTITION BY Inventory Detail.A,Inventory Detail.B,Item.C,Inventory Detail.D,MyDATE )/SUM(Inventory Detail.Qty) OVER(PARTITION BY Inventory Detail.A,Inventory Detail.B,Item.C )
How to use the OVER and PARTITION BY in OBIEE Expression Builder??
Thanks in Advance

hi bipin,
We cant use by in Expression builder(rpd) .But use the same formula like this in Fx of answers
SUM(Inventory Detail.Qty) OVER(PARTITION BY Inventory Detail.A,Inventory Detail.B,Item.C,Inventory Detail.D,MyDATE )/SUM(Inventory Detail.Qty) >OVER(PARTITION BY Inventory Detail.A,Inventory Detail.B,Item.C )SUM(Inventory Detail.Qty by Detail,ITEM,Mydate)/SUM(qty by detail,item)
First check the numerator whether it was giving correct results or not then go with denominator
compare the results with sql that u have
Let me know if that does work
thanks,

Marketing Attributes and Segment Builder performance

Hello!
Could you pls let me know
1. Maximum number of Marketing attributes one can create at -
    CRMD_PROF_CHAR - Maintain Attributes
2. What is the maximum number of BP's that can be taken into segment builder
    for Target Group creation without Segment Builder performance suffering
Thanks & Regards,
Raju

The solution for the problem is as follows,
When you upgrade to JRE 1.6 version 19 patch 4, in the graphical modeler, the filter drag and drop doesnot work. In this case,    add the following line in you JAVA POLICY file.
    permission java.awt.AWTPermission "accessClipboard","read,write";
    you can find the POLICY file in the path:
       C:\Program Files\Java\<JAVA VERSION>\lib\security
Please note that I found this in note 1359890

Checking for empty tags using expression builder for XPATH

I am creating several filters in a mediator for several parallel paths. I am trying to route the mediator to the correct DB adapter based on what tags are empty in the incoming XML. The XML has 1 required tag and 3 optional. So for the expression, I am using the expression builder to load the tag name then putting either [text()] or [not(text())] immediately after each tag with an "and" in between for the 3 optional elements. The problem I am having is they always return false. For example, if I enter a value for an optional tag and put [text()] after it, it evaluates to false. What is the correct way to check if an element has text or not?
Thanks in advance!

Hi,
Its not recognizing the getVariableData func... instead try this:
string-length(xpath)>0
ex: string-length($in.body/imp1:manoj/imp1:C1)>0
It works... Happy deploying ... :)

How to use TRUNC function with dates in Expression Builder in OBIEE.

Hi There,
How to use TRUNC function with dates in Expression Builder in OBIEE.
TRUNC (SYSDATE, 'MM') returns '07/01/2010' where sysdate is '07/15/2010' in SQL. I need to use the same thing in expression builder in BMM layer logical column.
Thanks in advance

use this instead:
TIMESTAMPADD(SQL_TSI_DAY, ( DAYOFMONTH(CURRENT_DATE) * -1) + 1, CURRENT_DATE)

Did you try to deploy the mapping ? Some time the expression validator gives wrong error messege.
Try to deploy the mapping and see if you are still getting this issue

Why is ADF Bindings node not displayed in Expression Builder window?

Hello,
I'm using Oracle JDeveloper Studio Edition Version 11.1.1.1.0, and I've created a Fusion Web Application and I've configured ADF Authentication and Security for my web project, using the provided wizard.
On a certain page, I've placed a Go Link component, and I'm trying to edit the Text and Destination Property using EL Expressions. When I open the Expression Builder window all I can see are the following nodes: ADF Controller Objects, ADF Managed Beans, JSF Managed Beans and JSP Objects, but no ADF Bindings. I need to access the securityContext properties, and from what I've read in B31974-03, I need ADF Bindings.
Also, I've tryied using the search field from the Expression Builder windows, without any luck.
This is probably a newbie problem, but I really can't figure it out. Please help.
Bogdan.

Hi,
maybe your problem is that you don't have created pageDef related with your page. Try right click on your page and Go To Page Definition. It will create the related pageDef if it does not exist.
Hope this helps

Can multi-select picklist be used in Expression Builder?

Does CRMOD allow the use of multi-slect picklist in Expression Builder within workflow?

Thanks Suddu your process worked. This can be done it is just a little more manual than being able to select the field from the drop down list.
To do this go to Admin, Application Customization, choose your record type, then Field Setup. Click on Rename Fields, then Advanced and copy the multi-select picklist field. Paste it into expression builder and at the end of the name add _ITAG. You will also need to add the brackets as well. Doing this will allow you to use a mspl in expression builder.
