How to use index of Oracle Table in EJB??

Hello I have a Table Department and it's index on Dpt_Name column.
I have created ejb - cmp in OC4J for Department Table.
I am getting all the data but it is not in index on department, Where I have to specify index of table in Oc4j.
Reply appriciated.
Rajiv

Rajive,
An index is used automatically by the Database for faster retrieval of data. The query optimizer in the database determines whether to use an index and which index to use for a SQL statement and you don't have to specify the index in OC4J.
If you have an index on deptname, then the index will be used when the SQL has a where clause like "where deptname = 'Personal' " or
"where deptname like 'P%' ", etc. In case of CMP, if you have a finder method called findByDeptName and then this index will be used.
For details on deciding on your indexing strategies please look at http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/appdev.920/a96590/adg06idx.htm#11977

Heterogeneous joins do not exactly scale and performance can be severely degraded by network speed and b/w availability. And there is nothing you can do in the application and database layers to address performance issue at the network level in this case - your code's performance is simply at the mercy of network performance. With a single glaring fact - network performance is continually degrading. All the time. Always. Until it is upgraded. When the performance degradation starts all over again.
If the tables are not small (few 1000 rows each) and row volumes static, I would not consider doing a heterogeneous join. Instead I would rather go for a materialised view on the Oracle side, use a proper table and index structure, and do a local database join.

Best way of Using Index on a Table.

I am trying to understand the phenomena of using INDEX on a Table
need some guidance!!!
Let us take this scenario
I have a table "MYRECORD" which has 4 attributes(or coulombs)
1. "STATE" (varchar) // this can have 49 different values like newyork, dehli etc
2. "YEAR" //a year like 2007
3. "MONTH" //a month like JAN,FEB etc
4. "CAT" (int) // type(category) of data represented by values 0 to 40
with a PRIMARY KEY(STATE,YEAR,MONTH,CAT)
now i will create index
1. INX_myrecord (STATE,YEAR,MONTH) on table MYRECORD
so now my question is
1. what is the effect on performance of DB it makes?
2. when I use a query
SELECT * FROM MYRECORD WHERE STATE="dehli" AND YEAR=2007 AND MONTH="JAN";
how will it get processed if index is created and not created.
3. how can I refer a index by name in a query if so possible?
Cheers,
UD

You have edited your post. Now you have a primary key consisting of state, year, month and cat which makes an index on state, year and month useless as the already existing primary key can provide for retrieval of rows by index. If you don't have other columns - or just few other not being large varchar2 columns - you should have created the table as an IOT (Index Organized Table - avoiding to have separate table and index containing - nearly - the same data) in the first place.
As a primary key by definition can contain only unique non null values, a query like SELECT * FROM MYRECORD WHERE STATE='dehli' AND YEAR=2007 AND MONTH='JAN' cannot give you more than the number of distinct cat values (0 .. 40) + 1 (if cat can be null - presumed one/some of the corresponding state, year and month is not null)
The information processing depends principally of the query, the mere presence of an index does not make sure it will be used. If an index is used it means the index will be searched first then the table rows will be accessed by rowids contained in the index (usually a single row or a range of rows - a rather small number of them - is retrieved this way, your select for example). Submitting something like SELECT * FROM MYRECORD WHERE YEAR=2007 AND cat=33 would most likely produce a full table scan of myrecord table ignoring the primary key.

How to use database look up table function in xsl mapping

Can anybody tell me how to use database look up table function while mapping xsl between 2 nodes.
I have an XML file coming in and depending on one of XML elements we need to decide which further path to take. But, using this XML element, we need to query database table, get metadata and accordingly take appropriate path. I have written lookup function which returns metadata value.
Now, the issue is how do I pass the XML element valu as input to look up function? When I tried to drag it to the input node of lookup function, it throws an error like "Maximum number of parameters exceeded"
Thanks,

If the lookup table is always going to remain the same (e.g. a character generator or something similar) you can place the values in a 2D array constant on your diagram, with the input value as one column, the equivalent as the other. When you need to perform the lookup you use an index array to return all the values in the "input column", search it using "search 1D array" and use the resulting index number to index the other column's data. If the values may change, then it would probably be best to load an array control with your equivalent values from a file.

How to enforce index in oracle query

how to enforce index in oracle query

Use INDEX hint to force Optimizer to use the specfied index.
You really need to investigate why Optimizer doesn't choose the index. Remember, INDEX SCAN are not always GOOD.

[HTML DB] How to use the existing database table?

[HTML DB] How to use the existing database table?
I installed Oracle 10g database in Computer A(Windows 2000), and I already create all the tables with data and the data size is about 300MB.
In Computer B(Windows 2000), I installed HTML DB 1.6.
How can I use /get the existing database table (in computer A) for HTML DB?
Could anyone help me on this? I am newbie and I need some detail instructions. or Where can I find the examples.....
Thanks

Well I guess if you wish to retain that architecture, i.e. HTMLDB on one machine and your data on another, you will have to establish database links to access the data. Oracle documentation will describe how to achieve that.

Regarding how to use index , please give me some example if possible

Hello everybody:
       Thank you all for your help in advance .
       would you please tell me how to use index, please give me some example if possible. couldn't thank you more!
      best regards .
     Frank

Index is used for faster access of data base tables.
An index helps to speed up selection from the database. An index is a sorted copy of selected database table fields.
The primary index is always automatically created in an ABAP-based SAP system. It consists of the primary key fields of the database table. This means, for each combination of the index fields exists a maximum of one record in the table. This kind of index is called a UNIQUE index.
If the primary index cannot be used to determine selection result, (for example, the WHERE condition does not contain any primary index fields), the system searches the whole table. To prevent this, and determine the selection result by searching through a restricted number of database records, you can create a secondary index.
However, you should not define an index for all possible fields in the WHERE condition.
Check this thread..u have more details.

How to use css in oracle forms

Hello, I am using oracle forms 11g with weblogic server 10.3.5 at windows 7.I have to use CSS in oracle forms.i have tried to search it but no profit.please some one else tell me that how can use css in oracle forms. Thnak You regards aaditya

Hi
As Francois pointed out Oracle forms has nothing to do with html based technology. The way you can get the equivalent effect of creating consistancy in the way your objects are displayed is by creating a set of items you want and alter their apperance and behaviour and place them into object libraries (one library should do the trick). From there you subclass all of you forms items off these libraries.

How to use application managed entity manager in EJB?

I finish reading The EntityManager Interface in JEE tutorial.
I know I can use container manager entity manager in EJB, but I want to explore how to use application managed entity manager in EJB.
Can I use application managed entity manager in EJB (container management JTA transaction is used)? Where do I should close entity manager if can?
The following is an example from JEE tutorial, but didn't find where to calose entity manager. and can I create mutiple EntityManagerFactory objects and Entity Manager objects to use them in a JTA transaction?
@PersistenceUnit
EntityManagerFactory emf;
EntityManager em;
@Resource
UserTransaction utx;
em = emf.createEntityManager();
try {
utx.begin();
em.persist(SomeEntity);
em.merge(AnotherEntity);
em.remove(ThirdEntity);
utx.commit();
} catch (Exception e) {
utx.rollback();

Seems like a very poor example, the whole power of EJBs is to use Container Managed Transactions so you don't NEED to manage the transaction and the entity manager yourself. What you posted is code I would expect in a non-JEE application, or in a piece of code which requires fine-tuned transaction boundaries such as batched data importing logic.
If I were you I'd research JPA in steps.
a) learn about JPA as an API outside of the scope of EJBs (recommended reading: the book 'Pro JPA 2')
b) learn about Container Managed Transactions in EJBs
c) learn about Bean Managed Transactions in EJBs
Right now you're rushing into c). I can understand that it raises many question marks at this point.

How to use indexes correctly in oracle

Hi guys
on one table i have indexes on 3 columns in the following order
a
b
c
When i m writing a select statement in my where clause what should be the order? like
where
a='some value' and
b='some value' and
c='some value';
or in reverse order like this
c='some value' and
b='some value' and
a='some value';
please let me know.
Thanks

If you have an index on a,b,c the difference in performance can be on the index order.
If column "a" has only 2 unique values then the sub values of the index only has 50% of the remaining values, the cost optimizer on Oracle will probably skip the index as an index scan of 50% is slower than a full table scan.
If a has 100 unique values then the remaining search is only on 1% of the values so is likely to be used.
As with any optimisation try using
explain plan for selec x,y,z from a_table
from where
a='some value' and
b='some value' and
c='some value'
If the index is not being used firstly try
analyze table estimate statistics
sample 10 percent
for all indexes
for all indexed columns;
and failing than try different orders in acceptance environment.

How to load data from oracle table to XML using ODI ?

Hello Team
I am trying to load data from an oracle table to an xml file. I have configured the physical and the logical schemas for the same. I have used SQL to SQL as LKM and SQL to SQL Append as IKM with Sunopsis Memory Engine as staging area.
After this, when I am executing the interface, it is executed without any errors but to my surprise I am not finding the relevant data in the xml file. What could be the reason ?
Please look into this and lemme know how to solve it.
Thanks.

Even IKM SQL Control Append is not solving the problem. There are many " order columns" in the target xml table. I have not mapped them or specified any order. Does the problem persist because of this ?
