Using user defined global functions
HelloI put implement Error Handling in a package. The logic goes like this:
If the call to the first interface fails, KO called the proc error using what error message is retrieved, written to a file and an e-mail notification is sent.
The code below is written in the procedure.
OdiOutFile-FILE=E:\OraHome_2\oracledi\demo\Assignmnt\ErrorLog.log
ErrMesg: "< % = odiRef.getPrevStepLog ("MESSAGE") % > '"
Now, I need to implement using a global function that can be used through interfaces to implement the error handling.
I want to club the code used above with the sending of a notification by e-mail.
Can someone pls guide me if I have my approach is correct and how this approach can be implemented using the global function?
Thank you.

Hi Ritika,
May I suggest a method?
Build a package, describe your flow of interface, the (failed) k of each interface, call OdiSendMail.
In the OdiSendMail set all settings such as mail server, from and to, subject to body of message code below, paste
Previous step <%=odiRef.getPrevStepLog("STEP_NAME")%> with the session number <%=odiRef.getPrevStepLog("SESS_NO")%> failed with the error message
* <%=odiRef.getPrevStepLog("MESSAGE")%>. *
Please look in the operator for more details.
So, what will the ODI is, it will send a notification to the recipient with the error message, the session number, and the name of the interface.
Sample:
Step previous INT_LOAD_AGE with the number of session 1822124 failed with the error message
17002: null: java.sql.SQLException: IO exception: the network adapter could not establish the connection
Please look in the operator for more details. Makes sense? http://img259.imageshack.us/img259/1704/screenshot003.jpg PS: Please close your threads accordingly award points (useful/correct) help experts for you with impatience. Thank you

CTX = null;
return a SUCCESS;
}
public BigDecimal ODCIAggregateMerge (oracle.sql.STRUCT ctx2) throws SQLException {}
return a SUCCESS;
}
}
To implement this in the database, I use the following script:
CREATE OR REPLACE TYPE IMPROG. SECONDMAX_J as object
(
INTEGER key,
public static function ODCIAggregateInitialize (sctx IN OUT SECONDMAX_J)
Return number
IN THE JAVA LANGUAGE

,
Member ODCIAggregateTerminate (self IN SECONDMAX_J function,
Return returnValue NUMBER, flags in number number)
IN THE JAVA LANGUAGE
NAME "Java.Math.BigDecimal return of SecondMax_j.ODCIAggregateTerminate (double [], int).
,
Member ODCIAggregateMerge (self IN OUT SECONDMAX_J function,
CTX2 IN SECONDMAX_J) return number
IN THE JAVA LANGUAGE
NAME "Java.Math.BigDecimal SecondMax_j.ODCIAggregateMerge return (oracle.sql.STRUCT)".
);
/
CREATE OR REPLACE FUNCTION F_SECONDMAX_J (NUMBER value) RETURN NUMBER
PARALLEL_ENABLE
AGGREGATION to the HELP of SecondMax_j;
/
When I now use the F_SECONDMAX_J function.
"(Columnname) select F_SECONDMAX_J from Tablename t;
It works perfectly and shows me the right result.
Then I tried to implement the fusion part as follows:
public BigDecimal ODCIAggregateMerge (oracle.sql.STRUCT ctx2) throws SQLException {}
BigDecimal Key2 = null;
BigDecimal ctx_max = null;
BigDecimal ctx_secmax = null;
BigDecimal ctx2_max = null;
BigDecimal ctx2_secmax = null;
retrieve the context stored with the key
StoredCtx_SecMax ctx = null;
try {}
CTX = (StoredCtx_SecMax) ContextManager.GetContext (Key.intValue ());
} catch (Exception e) {}
}
Object [] impAttr = ctx2.getAttributes ();
Key2 = (BigDecimal) impAttr [0];
retrieve the second context stored using the key2
StoredCtx_SecMax ctx_sec = null;
try {}
ctx_sec = (StoredCtx_SecMax) ContextManager.GetContext (key2.intValue ());
} catch (Exception e) {}
}
ctx_max = ctx. LeseMax();
ctx_secmax = ctx. LeseSecMax();
ctx2_max = ctx_sec. LeseMax();
ctx2_secmax = ctx_sec. LeseSecMax();
If (ctx2_max.compareTo (ctx_max) == 1)
{
If (ctx2_secmax.compareTo (ctx_secmax) == 1)
{
CTX. SchreibeSecMax (ctx2_secmax);
}
on the other
{
CTX. SchreibeSecMax (ctx_max);
}
CTX. SchreibeMax (ctx2_max);
}
on the other
{
If (ctx2_max.compareTo (ctx_secmax) == 1)
{
CTX. SchreibeSecMax (ctx2_max);
}
}
return a SUCCESS;
}
When I now try the function
"Select / * + parallel (t 4) * / F_SECONDMAX_J (Columnname) of Tablename t;
I always get a pointer NULL-error because the variable key2 is always 0 and therefore the functions LeseMax() and LeseSecMax()
in the second context 'ctx_sec' produce this error NULL pointer.
To me it seems that each parallel process is the construction of an additional class for himself, which is not available are my main process.
My question is now how it is possible to access the context of stored of the parallel process, so that I can combine the results.
Thank you very much
JosefHi Josef,
just guess that I've never implemented with java user-defined aggregate functions or support parallel execution:
Maybe you have to implement ODCIAggregateWrapContext?
+ Application of ODCIAggregateWrapContext is optional. It should be implemented only when the external memory is used to hold the aggregative, context and the user-defined aggregate is evaluated in parallel (which is, stated as PARALLEL_ENABLE). If the user-defined aggregate is not evaluated in parallel, ODCIAggregateWrapContext is not necessary. +
[http://docs.oracle.com/cd/B12037_01/appdev.101/b10800/dciaggfns.htm#i1004974]Report it to progress and success.
Good luck

THT of the user-defined aggregate function includes 'in the GROUP BREAST"
There are a lot of library functions in Oracle that can be used with the clause "WITHIN GROUP".
Is it possible to create the UDA who works in the same way (in whatever language)?
Function I created can be called with clause but not with "WITHIN GROUP".
Any ideas?

HW to generate topics using user-defined thesarus
Hi all
We have created a thesaurus and transferred to the database using the command ctxload.
We have compiled the thesaurus using ctxkbtc to create a knowledge base.
But we want to use only the new dictionary of synonyms to generate themes of our text data.
How can we do this? Please suggest to go about it.
Thanks in advance.I think that means the author of the question ' how can I ignore the current contents of the knowledge base? Unfortunately you can't do - theme queries are still operating against the base of knowledge expanded together.

Xquery functions using predefined in user defined functions
Hi all
I have a requirement to call a function defined by the user in the osb xquery file. That function, I use osb predefined string functions, but they do not work it displays the error message in the file of xquery. Can you please suggest how to use user-defined functions.
Thank you

Writing user defined function the same way as the oracle functions
Hi guys,.
In one of the interviews, I saw the guy asked me to write a function defined by the user who will be the column name and the list of all values.
For example
Name: employees table
Column name: Employee_Name
Employee_name
Scott
Ivgun
Jack
Shane
The query must be in this marker
SELECT col_agg (Employee_name) emp_name of employees;
The output must be
Emp_names
Scott, ivgun, jack, shane
Please let me know if this is possible
Any suggestions will be much appreciated.
Thank you

variables of user-defined data transfer
Hello
I use the etherCAT 9144 chassis and is only supported by this hardware FIFO range target. After a search, I realized that the only way to transfer data from FPGA to the host by using user-defined variables. But these variables do not support the notion of FIFO. So which is the best practice to transfer data after measures (provable 10 Hz measurement of 15 values) to host VI?
Thank you
As mentioned, the 9144 only supports the analytical engine.
In regards to what you do, it really depends on the entire application. For example, what is the master? Are there other systems at issue here? Etc. It's a good read, in general, although it might not help this second right: http://www.ni.com/white-paper/14151/en/
A high level, you need to decide what you need. If you have need for deterministic communication, low-latency over long distances from a RT controller, the 9144 is probably the right choice. If you need low latency + streaming over short distances to a RT controller, you should look into the RIO MXI chassis. If you need mainly not deterministic low speed (10 hz) data mixed with low flow continuous over long distances to a windows or host RT, then ethernet expansion rio (9146,7,8,9) is probably the right choice. If you need high speed continuous with low control latency over long distances to a windows or RT host, you need a full cRIO controller. Based on what you've posted so far, its uncertain is the right person.
Lets say you're stuck with the 9144 for now. As you can easily hit 1 kHz scanning cycles, it should be perfectly possible to data 'stream' to 10 Hz. If you run the scan at 1 kHz engine, then you are 100 x oversampling. Where it gets complicated is this requirement of sync. By default, acquisition input/output is synchronized to the clock of the scan (and you can see when the clock of scan is set by a knot of e/s FPGA). However, you can take complete control of a module in the FPGA and read inputs and outputs at any time if you please. In other words, you can set up so when DIO0 goes high you immediately enjoy all the values of AI 15. You can then transfer these values HAVE switched to the host using the user-defined variables.

I just noticed that these files appear to be copyrighted. My first question is do you have author permissions to post them in a public forum? If this isn't the case, then you can remove them. That being said, I have reviewed the code and it seems easy enough to work around your problems (provided that you have the copyright permissions). How to bypass the problems is to replace the fields of the struct with variables. There is of course allows you to change some definitions of functions for input and output the necessary variables which I think was the best 5 variables. You will also need to redo the code that uses a table of error checking cell. In total, I estimated about 30 minutes of work. I would have given you work around these files had not been protected by copyright. So, unfortunately, you will need to implement the work around you.

User-defined function: BAD ARGUMENT TYPE, ERROR
I am creating a function defined by the user, named DOTAN, to calculate the angle between two vectors X and Y. The UDF looks like this: DEFINE (' DOTHAN (X, Y) = ACOS (DOT (X, Y) / (ABS (X) * ABS (Y)))')--> (see pic attached to the actual Calculator display). The problem is that I can not set because as soon as I hit ENTER I get the warning: DEFINE ERROR: wrong Type of Argument. I tested each component separately and I am sure that the problem is with the help of DOT (X, Y) inside a UDF, but I don't know why. Maybe I'm missing some setting related to the use of functions which take an argument that is greater than 1 inside a UDF. Just guessing. Any idea?
Thank you
for some reason, the DOWRY is a commandment and not a function for the 50G.
You cannot use DOT in a function, you maybe wrote a program
in RPL
'--> x, y ' x y DOT XY ABS ABS * / ACOS ' ""DOTHAN"STO

I don't know what means your post, so here's how to create a user-defined function:
1) click Start
(2) select "Control Panel".
(3) select "system and maintenance".
4) click on "Administrative Tools".
5) click on "Task Scheduler."
(6) click on "create task" (right in the list pane under) "Actions") "
"(7) opened in the general tab it will choose if it only works when the account that is used to implement is connected, or ' if that user is logged in or not" (leave the box ' do not store the... "empty password)
(8) always in the general tab, check the box 'run with highest privileges '. (This will ensure that no program can block)
(9) type a name for the task (in the general tab)
(10) to set the job to run an awhile, use the "triggers" tab, if you want to set a task runs after xx min. temps_inactivite, choose the 'conditions' tab, then choose the desired time.
(12) click on the 'actions' tab click on 'new '. in the program/script line, search for and select the program you want to run, and then click Open.
13) click OK in the window "create a task".
14) click OK again and you are done.
I hope this helps. -

None of the answers was * exactly * correct, but they gave me enough information to solve the problem.
To implement what I have to code the functions a bit differently.
- BPEL functions are all the IXpathFunction extension classes.
- Mapper functions are not.
- BPEL functions are each separate classes.
- A single class with a method for each desired function mapper functions.
- BPEL classes outcrop in the config file ext-bpel-xpath-functions-config. XML
- The Mapper class is exposed in the config file ext-Mapper-xpath-functions - config.xml
A BPEL class looks like:
public class editCaseNumber implements IXPathFunction { public Object call(IXPathContext context, List args) throws XPathFunctionException { return docOut; } }
A class to map looks like:
public class mapperFunctions { public static String replaceString(String sIn,String sMat,String sRep,String mode){ return finalString; } public static XMLDocumentFragment compressFile(String indoc){ return docOut; } }
(I deleted the code of these to avoid confusion.)
My ext-Mapper-xpath-functions file - config.xml looks like:
soa-xpath-functions xmlns="http://xmlns.oracle.com/soa/config/xpath" xmlns:map="http://www.oracle.com/XSL/Transform/java/com.f17.customfunction.mapperFunctions" version="11.1.1" resourceBundle="oracle.tip.tools.ide.common.resource.IDEMessageBundle" >

any user defined function in the rule set by the user
Hello
I wonder if I can use a function defined by the user in a rule set by the user in oracle sem... I've seen examples of user defined function the used in sparql query filter clause in this guide to dev... However, I don't know if I can define a function in oracle database SEM. and use it in the body rule or the head. For example, I want to define a function of the length that allow to calculate the difference between two dates. So, I want to set a rule as follows: event1: d1 and event1 has_start_date: has_end_date d2 and duration (24, d1, d2) then event1:date_satisfiable 'yes '. Oracle supports this type of rule? Thank you very much.

Salvation Hong,
User-defined in 12 c inference can be a good choice for your condition. Please see the following document.
Defined by the user and querying inference

User defined function join VS - Performance...
Hi all
all connecting mulitple table and get values... which one is the best?
Join or user-defined function...
row function
--------------------------
Select b.SID, get_salary (empid) from emp;
Note: get_salary function will return the salary of the pay tables.
Using joins
--------------
Select b.SID, b.salary from emp, a, b of salary
where a.empid = b.empid;
What is the best performancewise?
also if you give any related document also very well.
Thanks in advance.

Hi, experts,
I wrote a sql query to get the amount after calculation.
It runs correctly, and no error returned.SELECT A.FORM_NO, C.SKUCODE, B.QUANTITY * ( CASE WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) = 2008 AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) = 2008 THEN TO_NUMBER(TO_CHAR(A.END_DATE,'MM')) - TO_NUMBER(TO_CHAR(A.START_DATE,'MM')) +1 WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) = 2008 AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) > 2008 THEN 12- TO_NUMBER(TO_CHAR(A.START_DATE,'MM')) + 1 WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) < 2008 AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) = 2008 THEN TO_NUMBER(TO_CHAR(A.END_DATE,'MM')) WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) < 2008 AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) > 2008 THEN 12 ELSE 0 END )/((TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) - TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY'))) *12 + TO_NUMBER(TO_CHAR(A.END_DATE,'MM')) - TO_NUMBER(TO_CHAR(A.START_DATE,'MM')) + 1 ) AS QUAN FROM FORM_TBL A, QUANTITY_TBL B, SKU_TBL C WHERE A.FORMNO = B.FORMNO AND B.SKU = C.SKU;
I would change for a user-defined function.
BUT IT CANNOT BE COMPILIED.create or replace function get_quantity (pi_year number, pi_year_diff number, pi_form_no varchar2, pi_skucode varchar2) return number is po_quantity number; begin SELECT ( B.QUANTITY * ( CASE WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) = (pi_year + pi_year_diff) AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) = (pi_year + pi_year_diff) THEN TO_NUMBER(TO_CHAR(A.END_DATE,'MM')) - TO_NUMBER(TO_CHAR(A.START_DATE,'MM')) +1 WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) = (pi_year + pi_year_diff) AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) > (pi_year + pi_year_diff) THEN 12- TO_NUMBER(TO_CHAR(A.START_DATE,'MM')) + 1 WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) < (pi_year + pi_year_diff) AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) = (pi_year + pi_year_diff) THEN TO_NUMBER(TO_CHAR(A.END_DATE,'MM')) WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) < (pi_year + pi_year_diff) AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) > (pi_year + pi_year_diff) THEN 12 ELSE 0 END )/((TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) - TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY'))) *12 + TO_NUMBER(TO_CHAR(A.END_DATE,'MM')) - TO_NUMBER(TO_CHAR(A.START_DATE,'MM')) + 1 )) into po_quantity FROM FORM_TBL A, QUANTITY_TBL B, SKU_TBL C WHERE A.FORMNO = B.FORMNO AND B.SKU = C.SKU and c.skucode = pi_skucode and a.form_no = pi_form_no; return po_quantity; end;
The error is a recursive sql error
ORA-00604: an error has occurred at the SQL level 1 recursive
I think that there is no syntax error.
What is the reason?
Thank you very much!What is your DB version. If you are using 11g then can be consider that

User-defined function problem. Help!
I can't get the user-defined function to work in Essbase, although it seems to be just registered. Could someone help me to have a look at java codes below? Greatly appreciated!
public class {depreciation
public static double Adeath (double r, int period, double LoanBalance) {}
Calculate amortization payment
Double LBound = LoanBalance/period;
Double UBound = LoanBalance;
Double MBound =(LBound+UBound)/2;
Double err = 0;
int i = 0;
If (r < 0 |) Period < = 0 | LoanBalance < = 0) {}
MBound = 0;
}
ElseIf (period == 1) {}
MBound = LoanBalance *(1+r) ;}
on the other
{}
Double MBalance is PVCalc (r, Period, MBound);.
ERR = MBalance-LoanBalance;
If (err > 0) {}
UBound = MBound ;}
If (err < = 0) {}
LBound = MBound ;}
MBound =(UBound+LBound)/2;
i ++ ;
}
While (err > 0.001 | err <-0,001 & & I < = 100);
return (MBound);
}
Define the present value
public static double PVCalc (double rate, NPER, double PMT int) {}
Double pvpmt = pmt;
Double cpvpmt = 0;
for (int j = NPM; j > 0; j-) {}
for (int i = 1; i < = j; i ++) {}
pvpmt = pvpmt /(1+rate/12);
}
cpvpmt = cpvpmt + pvpmt;
pvpmt = pmt;
}
Return cpvpmt;
}
}
Is there something to do with the double data type, int, double? Essbase spend 'int '?
Help, please! Thank you very much!!
Published by: user9132709 on March 2, 2010 12:47I just tried and it works.
I also added
System.out.Print (MBound);
just before the return (MBound);
in the Java class
I created a calc script against Sample.Basic
Fix("Florida","100-10","Actual","Apr")
('Sales'
'Sales' = @Amort (0.06, 360, 10000000);
)ENDFIX
I run essbase in the foreground, so I see the exit of System.out.print (Mbound);
Validated the script "59955.05251799688" was written in the output window, so the Java class works.
I also ran the calc script and the value was written in 'Sales' (the block already existed for the POV before anyone says that my script would not work)I registered the CDF of Java with.
create or replace function '@AMORT' as
"Amortization.Amort (double, int, double).You must ensure that you see something like the following in the application log or output in the command window.
External function of [GLOBAL] [@AMORT] saved OK
See you soon
