User-defined index
Where I can find information/tutorial/"how-to" about how create/implement my own index in Oracle? Maybe there is somewhere step-by-step instruction. I read about OraGiST, Data Cartridges and Extensible Indexing.
I want to compare my own R-tree variant with the oryginal one - It is possible to perform? What parameters should I compare?
Kerad555
Other than that, I don't know what you mean. You can read more about Extensible Indexing in the Data Cartridge Developer's Guide

Ceartion of User Defined Field in EXCHANGE RATE AND INDEXES
Hi Experts,
I want to create User Defined Field in EXCHANGE RATE AND INDEXES.But while creating the UDF from User Defined Field-Management unable to find the table for it.Write now My Client are using SAP B1 2007 Ptach-08.Is there any way out to create user defined field in EXCHANGE RATE AND INDEXES.
Plz help me out on this issue.
with regards,
Pankaj K and Kamlesh NPankaj,
When you do the Manage User Fields area to define a UDF, all the possible areas where UDF's can be created in B1 is listed. You would be able to create UDF's only on these.

After having created a filter and defined a search criteria, SAP says to "create an index of the messages that match the active filters and search criteria" [Link|http://help.sap.com/saphelp_nw73/helpdata/en/48/b2e0186b156ff4e10000000a42189b/content.htm]
Every time I try to run indexing it fails. I don't know why as there is no help-button available and I haven't found anyone experiencing the same issue. Anyone else experienced the same issue?
Also - using XPath - do I have to consider any particular namespace prefix etc for PI messsages? I have tested my XPath on payload XML in XMLSpy, but the search functionality seem to expect a different format on the XPath syntax...
Thank you!
regards OleHello,
I have set this up for an interface now. I am not sure how important the index job is because
the indexing job worked in the dev system, never stopped in QA and failed in prod. Anyway the message search works in all three systems.
The following blog made me understand the namespace prefix:

Creating Index on user defined function
Does anyone know if you can create an index on a user defined, or system defined function like LOWER or UPPER in Oracle 8i?
According to Steve Yam's previous post:
DO you turn on the QUERY_REWRITE_ENABLED within session or instance? You need to
have this to utilize function based index in query.
Besides, Oracle may still use FULL TABLE SCAN if your table size is not big enough for
using index search. Determine number of blocks occupied by the table and determine
whether you really gain from the index.

User defined tables: amending Index on the database level. Opinions???
Hi everybody who has some spare time to read my stuff
I had a problem that some of you might have had. I have a user defined table, lets call it ProductTypes. Now system by default creates two columns in this table, one is Code (primary key) and another is Name (Index). I have added third column called Department. Now, if I wanted to add the following data (see bellow) to the table I would have had a constraint violation message pointing me out that I have problems with indexing.
Code, Name, Department
1, Cream, Fragrances
2, Cream, Beauty Products
^^
I could thing of couple workarounds of this problem
1. Is to duplicate Code into Name and storing rest of the data using user columns
Code, Name, Product Name, Department
1, 1,Cream, Fragrances
2, 2, Cream, Beauty Products
This approach isnt very convenient as it requires UI development should we decide to attach this table to the Item master data form in a form of combo box.
2. Is to amend Index on the database level. Initially, the index KProductTypes_Name consisted of only one column Name, what I have done is added another column which is Code to indexing. I dont see how this can harm database consistency or damage the core system. Please correct me if I am wrong.
Another way of amending index in order to solve my problem could be choosing ignoring duplicate values option for column Name.
Please let me know what are your thoughts.
Best wishes> Why don't you try adding a trigger 'instead of
> insert' where code = max(code)1 and name=max(name)1
> and use only user columns for your data. This
> provided you know SQL basics.
in this scenario we would have to do UI SDK development for the output and going to have an extra column with meaningless data in it. -
About semantic indexing using user defined ontology
hi zhe,
according to the dev. guide, you can do semantic index on a document using user defined ontology. however, multiword class names, individual names and property names defined in the ontology are usually concatenated and cannot have space. if I have a multiword concept such as "http://www.example.org/medicalProblem/DiagnosedPastNeurologicalDeficit" rather than "http://www.example.org/medicalProblem/Diagnosed Past Neurological Deficit" in the ontology and a loaded document in the table also contains the concept "Diagnosed Past Neurological Deficit", so how is the extractor able to identify the concept in the document? do I need to describe the concept in the ontology using rdfs:lable like this "<rdfs:label xml:lang="en">Diagnosed Past Neurological Deficit</rdfs:label>" so that extractor can identify the concept in the document? I am not clear how to use user defined ontology to semantically index documents. thanks a lot in advance.
hongHi Hong,
The semantic indexing feature is itself a framework. There is no native NLP engine bundled with it.
There are NLP engines like Open Calais, GATE, and Lymba that can work with this framework. Some engines
can take an ontology and map entities (events, individuals, relationships etc.) embedded in the text to definitions in the ontology. You can also perform the mapping yourself. For example, you can take out the rdfs:label (or comment, or some other descriptive parts) of URIs, build an Oracle Text index, perform a fuzzy text match for a given piece of phrase, and select the URI that gives the best matching score.
Hope it helps,

How to Manage index of user define dimensions
When I create a new rate application,The BPC system throw the message"Index was out of range:must be non-negative and less than the size of the collection parameter name :Index".
I searched oss notes:1323195 saying :"A user can change the index of user-defined dimensions by clicking a button named "Manage Index" in "Modify application". The button will be shown if**
*there are user-defined dimensions already assigned to an application or at*
*the moment of assigning a user-defined. If the button is clicked a windows*
*will popup, and the user can maintain a user-defined dimension index from*
*the window."*
But i can't find the menu "manage index" .
could someone tell me how to find it?
thanksJust go trough Manage application and Modify application and use reindex and full process.
This normally should fix your issue.

Adding user-defined number of text fields.
Okay I am having problems, obviously. I am developing a program where the user will enter X and Y values and the program will calculate the relational data. However, I can't even get a start.
First of all, the user defines the number of pairs of points they want to define. For example, they have 20 points, each with its own X and Y, so they click on 20 and then okay in the first window.
The next window will then take their answer and display X and Y text fields for as many points as they defined. However, I can't figure out any way to do this.
Feel free to run the program, the problem lies in the method setTextFields(). Help please!

Table OF user defined type in c#
Hello
I am running C# using Oracle (PL/SQL, provider ODP.NET
11.1.0.6.20) and I have a procedure which at the moment returns a table of
records. The code below demonstrates this.
TYPE R_OutData_tab IS RECORD ( ... );
TYPE OutData_tab IS TABLE OF R_OutData_tab INDEX BY BINARY_INTEGER;
PROCEDURE PROPERTY_GET (tOutData OUT <packagename>.OutData_tab);
Since .NET doesn't support Oracle records I'm looking into rewriting the
procedure so that it returns a table of a user defined type instead. The
code below demonstrates this.
create type person_type as object (name varchar2(30), address varchar2(60),
age varchar2(3));
TYPE person_table IS TABLE OF odp_obj1_sample_person_type;
PROCEDURE PERSONS_GET(out_persons OUT person_table);
I know how to handle a single user-defined type in .NET returned from a
Oralce procedure but what I need to do now is to receive a or pass table of a user
defined type using procedure. Is this supported in .NET?Dear ,
I have posted a similar kind of reply in one of the thread which may help u defining the User Defined Tabel /Filed .Just check this Out :
For cm25/CM21 : Assuming that you have all the other set up for Capacity Requirement in place , please note the belwo steps for layout design for CM25 OR cm21 or cm22( all you will be used same overall profile )
1.Make sure that you have proper Overall profile defined in OPD0-Define Overall profile .Here u will define Time Profile , Startegy prfoile . Lay out Profile etc .
2.To paint your layout your soultion is to Goto -CY38-Pop down the menu -Select the Lay out Key which have been used as lay out -Goto Change Mode (Pencil symbol)-Now you will find the fields are high ligheted as per CM25 dipaly in a sequnce -You can un chekcde the Filed like Operation , Operation text , Setup what ever you do not want to show in Order Pool and Hit SAVE butotn and come back .
CM25 --> Settings --> Display Profiles --> Planning tab.profile --> I01 --> Layout ID ( Example : 'SAPSFCLA05') which is Main Capacity Lay out id .
If you goto CY38-Pop down the menu -You will find Main Capcitity Lay out Id : Example SAPSFCAS01 -Enter this lay out and chenage accordingly as I have explained in above
Once you save this , then go back to CM25 and execute with coupe of work centres to check how is the order pool looks now .
Refer this threade for Layout Id and option which u may need for CM25 front end
Exception messages in CM21 or CM25
I hope this should work

Access result set in user define type of table
here is the situation. I have a stored procedure that dequeues messages of a AQ and passes them as an OUT parameter in a collection of a user defined type. The same type used to define the queues.

I know this should be doable but........Can someone please tell us what we are doing wrong....thanks in advance.

}Hi,
Sorry but I'd refer you to the following sections (and code samples/snippets) in my book:
Mapping User-Defined Object Types (AD) to oracle.sql.STRUCT in section 3.3, shows how to pass user defined types as IN, OUT,IN/OUT
JMS over Streams/AQ in the Database: shows how to consume AQ
message paylod in section 4.2.4
CorporateOnine, in section 17.2, show how to exchanges user defined type objects b/w AQ and JMS
All these will hopefully help you achieve what you are trying to do.

User-Defined Function and Context Manipulation
Hi Mapping Gurus, I need your help.
I have a user-defined function and one of my input parameter (c) is in a loop (EDI segment). So one, if I execute my function I get:
Exception:[java.lang.ArrayIndexOutOfBoundsException: 0]
If I change the context or use the remove context node function its working but its always taking the first row in consideration since I'm using c[0] . Here is the logic:
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[0]"'";
So since c is an array [], I have tried different logic to get to the right row.
1- I tried using another parameter (e) to pass a counter or an index to my function. So each time it's looping, it's passing a new value to the function but Im still getting the first row and Im not to sure why?
int G = Integer.parseInt(e[0]); // e[] = My counter field
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
2- I tried using a parameter stored in the container:
String Num;
Num = (String)getParameter(counter);
if (Num == null) G = 0;
else
G = Integer.parseInt(Num);
G = G + 1;
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
Num = "" + G;
setParameter(e[0], Num);
and Im still getting the first one, look like its using a different container each time its looping so the Value is always the same?
4- I created a new user-defined function with the container logic, then its working but Im back to the same problem in my main function, its only looking at e[0] for my counter all the time.
5- I tried using the Seeburger Java Variables and guess what in the main fonction, as new UDF,... and guess what, same result!
So anybody out there that was able to get UDF's working into a multiple context scenario?
Am I missing something?
I will reward points and beer for any help!This is one of the text with passing a counter to the function to try to go to the right row in the array since I'm doing a remove context and I'm getting all the d_234's:
public void ReadTable(String[] a,String[] b,String[] c,String[] d,String[] e,ResultList result,Container container){
int G = Integer.parseInt(e[0]); // My counter
String var;
String DBTABLE = a[0];
String lookUpField = d[0];
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
Now this one was with the internal container logic:
int G;
String DBTABLE = a[0];
String lookUpField = d[0];
String Num;
Num = (String)getParameter(e[0]);
if (Num == null) G = 0;
else
G = Integer.parseInt(Num);
G = G + 1;
Num = "" + G;
setParameter(e[0], Num);
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
And now with the Seeburger Variables:
int G;
try {
VariableBean be=VariableFactory.getVariableInstance("");
G = Integer.parseInt(String.valueOf(be.getStringVariable("yves")));
} catch (Exception f) {
throw new RuntimeException(f);
String DBTABLE = a[0];
String lookUpField = d[0];
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
try {
G = G + 1;
Num = "" + G;
VariableBean be=VariableFactory.getVariableInstance("");
be.setStringVariable("yves",Num);
catch (Exception f) {
throw new RuntimeException(f);
All 3 logics were returning always the first row or a counter of 1 if the logic is in the main ReadTable function. -
User-defined function in order by?
Hey guys. We're trying to port our postgres db to Oracle, and I'm stumbling on this one issue. We have columns called 'sortSequences', which are arbitrarily long arrays of integers. For POC purposes, I am using varray(), but that probably won't work as an production implementation, because of it's strongly-defined size. Anyway, the crux of the problem is that I need to be able to select * from foo order by sortSequence, where the ordering evaluation is custom code. The array of integers essentially represent infinite-precision math, and we have a deterministic algorithm for comparing them, but one cannot simply produce a value from them (which I think prevents me from using a map member function in a user-defined object type.) In other words, we don't really care what the values are, we are just using them collectively as a sorting index. An aggregate function didn't look like the right answer, and a simple scalar function is out of the question. We were looking at domain indexes, but it's not clear to me that even if we created an operator bound to our user-defined type that the db would use that function for order by evaluation...
Can anybody think of a solution for this problem? If we absolutely have to live without this functionality, we can replicate it in app code, but we wish to avoid that at all costs...
thanks,
brianDoesn't look very promising for a general case.
Even for short sequences and moderate number values the computed numbers to order by are quite large.

Using User Defined Function is SQL
Hi
I did the following test to see how expensive it is to use user defined functions in SQL queries, and found that it is really expensive.
Calling SQRT in SQL costs less than calling a dummy function that just returns
the parameter value; this has to do with context switchings, but how can we have
a decent performance compared to Oracle provided functions?
Any comments are welcome, specially regarding the performance of UDF in sql
and for solutions.
create or replace function f(i in number) return number is
begin
return i;
end;
declare
l_start number;
l_elapsed number;
n number;
begin
select to_char(sysdate, 'sssssss')
into l_start
from dual;
for i in 1 .. 20 loop
select max(rownum)
into n
from t_tdz12_a0090;
end loop;
select to_char(sysdate, 'sssssss') - l_start
into l_elapsed
from dual;
dbms_output.put_line('first: '||l_elapsed);
select to_char(sysdate, 'sssssss')
into l_start
from dual;
for i in 1 .. 20 loop
select max(sqrt(rownum))
into n
from t_tdz12_a0090;
end loop;
select to_char(sysdate, 'sssssss') - l_start
into l_elapsed
from dual;
dbms_output.put_line('second: '||l_elapsed);
select to_char(sysdate, 'sssssss')
into l_start
from dual;
for i in 1 .. 20 loop
select max(f(rownum))
into n
from t_tdz12_a0090;
end loop;
select to_char(sysdate, 'sssssss') - l_start
into l_elapsed
from dual;
dbms_output.put_line('third: '||l_elapsed);
end;
Results:
first: 303
second: 1051
third: 1515
Kind regards
TaoufikI find that inline SQL is bad for performance but
good to simplify SQL. I keep thinking that it should
be possible somehow to use a function to improve
performance but have never seen that happen.inline SQL is only bad for performance if the database design (table structure, indexes etc.) is poor or the way the SQL is written is poor.
Context switching between SQL and PL/SQL for a User defined function is definitely a way to slow down performance.
Obviously built-in Oracle functions are going to be quicker than User-defined functions because they are written into the SQL and PL/SQL engines and are optimized for the internals of those engines.
There are a few things you can do to improve function
performance, shaving microseconds off execution time.
Consider using the NOCOPY hints for your parameters
to use pointers instead of copying values. NOCOPY
is a hint rather than a directive so it may or may
not work. Optimize any SQL in the called function.
Don't do anything in loops that does not have to be
done inside a loop.Well, yes, but it's even better to keep all processing in SQL where possible and only resort to PL/SQL when absolutely necessary.
The on-line documentation has suggested that using a
DETERMINISTIC function can improve performance but I
have not been able to demonstrate this and there are
notes in Metalink suggesting that this does not
happen. My experience is that DETERMINISTIC
functions always get executed. There's supposed to
be a feature in 11g that acually caches function
return values.Deterministic functions will work well if used in conjunction with a function based index. That can improve access times when querying data on the function results.
You can use DBMS_PROFILER to get run-time statistics
for each line of your function as it is executed to
help tune it.Or code it as SQL. ;)
