How to use Oracle Client

Dear Buddies,
To the best of my knowledge I understand that Oracle Client is a minimal package to get connected to the Oracle Server in order to access the database. Corrrect me if I am wrong.
I have installed it based on the steps given in http://www.oracle.com/technology/tech/oci/instantclient/index.html
and also other sites.
How do I start using it? If SQL Plus, all I have to do is launch the SQL Plus, get connected and start using the database. How should I use this Instant Client? Please guide me. Is it compulsary to use it with SQL Plus? or some other tools?
I also tried the methods mentioned in this pdf http://www.oracle.com/technology/products/oraclenet/files/OracleNetServices_NetEasyConnect.pdf
but it doesn't help me as well.
Expecting your support and reply.
Thanking you in advance.

You need a client program that uses Oracle client to connect to an Oracle Database.
One such program is "sqlplus", it is the command line interface.
Its usage is described extensively in
http://download.oracle.com/docs/cd/B19306_01/server.102/b14357/toc.htm
See specifically
http://download.oracle.com/docs/cd/B19306_01/server.102/b14357/ch3.htm#sthref610
for how to connect to a database.

How to start to use Oracle client to access Database ?

Folks,
Hello. I have just installed Oracle Client into directory /home/myOracle/Oracle_Client. But I don't know how to start and configure the client to access Oracle Database.
Can any folk tell me how to start to use Oracle client to access Database ?

I have earlier managed to install the Oracle Client (32-bit) in 32-bit clients and servers Oracle Client 10.
The reason that it went well before was the exellent setup and configurationprograms we got with that version.It seems you are confusing the "full" Datbase Client with Instant Client.
Now I'm trying to install the Oracle Instant Client 11g R2 both 32-bit and 64 (of the latest revision) on a 64-bit Windows 2008 Server .
I have managed to install the driver but the setup doesn't give me any Net Configuration Assistant or Net Manager to help with the configuration.What setup? Are you not using just the zip files?
What are you installing exactly, i.e. what install media (file) did you download?
So I haven't succeded in configuring it despite I I read the readme-info that comes with the Instant Client files.There's not much to configure - that's sort of the point of Instant Client. Just drop a few files in a folder, set PATH and off you go.
Doesn't <instant client dir>\sqlplus user@'hostname/servicename' work?

How to use Oracle partitioning with JPA @OneToOne reference?

Hi!
A little bit late in the project we have realized that we need to use Oracle partitioning both for performance and admin of the data. (Partitioning by range (month) and after a year we will move the oldest month of data to an archive db)
We have an object model with an main/root entity "Trans" with @OneToMany and @OneToOne relationships.
How do we use Oracle partitioning on the @OneToOne relationships?
(We'd rather not change the model as we already have millions of rows in the db.)
On the main entity "Trans" we use: partition by range (month) on a date column.
And on all @OneToMany we use: partition by reference (as they have a primary-foreign key relationship).
But for the @OneToOne key for the referenced object, the key is placed in the main/source object as the example below:
@Entity
public class Employee {
@Id
@Column(name="EMP_ID")
private long id;
@OneToOne(fetch=FetchType.LAZY)
@JoinColumn(name="ADDRESS_ID")
private Address address;
EMPLOYEE (table)
EMP_ID FIRSTNAME LASTNAME SALARY ADDRESS_ID
1 Bob Way 50000 6
2 Sarah Smith 60000 7
ADDRESS (table)
ADDRESS_ID STREET CITY PROVINCE COUNTRY P_CODE
6 17 Bank St Ottawa ON Canada K2H7Z5
7 22 Main St Toronto ON Canada L5H2D5
From the Oracle documentation: "Reference partitioning allows the partitioning of two tables related to one another by referential constraints. The partitioning key is resolved through an existing parent-child relationship, enforced by enabled and active primary key and foreign key constraints."
How can we use "partition by reference" on @OneToOne relationsships or are there other solutions?
Thanks for any advice.

How to connect sql server using oracle Client

Hi,
I am working in oracle9i and windows os 32 bit.
I need to connect SQL server 2000 from my oracle client..
I heard about heterogeneous connectivity ...
Please expalin me the steps what to add and how to connect the sql server...
Regs....

Are you trying to connect to SQL Server from your Oracle database (i.e. create a database link in Oracle to SQL Server)? Or are you trying to connect to SQL Server using your Oracle client software (i.e. SQL*Plus)?
The former just requires Heterogeneous Services with Generic Connectivity. The latter is functionality that has been depricated and probably no longer works in your environment.

How i install oracle client with ODBC using response file method

Hi,
I have managed to create a response file using OUI. Currently, I do not know what are the methods which i can install a group of computers using this response file. Any advise
Thanks in advance.
Best regards,
Tony

Presumably, any method that allows you to remotely run code on the group of computers would allow you to do a silent install of the Oracle client and ODBC driver. I know Microsoft and various third parties sell such tools, but I'm not enough of a Windows admin to know anything about the relative benefits of the products in this category.

How to use Oracle Spatial in this scenario

My scenario is like that:
I'm very new to Oracle Spatial
I'm building an application that will be based on asp.net.(I am
confident about .net)
As per my client requirement there are some kml file in one archive
folder.
Let me give an example:
say there is a kml file for region A.(latitude say 36 n to 40 n and
longitude is 110 w to 115 w) already in the archive folder.
Now if a new kml file(say A1.kml) that has been created by the user
and say its latitude and longitude are respectively 37n and 112w. As we clicked A.kml, google earth is opened up for the region A and as
we move our mouse cursor to more deeper more polygons are visible.
eventually polygon for A1.kml is also visible and definitely which is
inside the polygon for region A.
How can I achieve this thing by using oracle spatial 10g? ---(it's one of my senior's advice to use "oracle spatial 10g" in this scenario)
I'm not too sure whether I can able to make it clear to u about my
situation; plz xcuse me if I'm wasting ur valuable time.

How to use oracle.sql.* package?(in nls_charset12.zip)

is there anyone could tell me how to use the method in this package? for i want to convert a character set from the database (solaris)default character set to the client(win2000) while storing data into ResultSet.
or anyway that could chnage it would be appricate.
thanks in advice,

Hello Gaurav,
First off, not sure why you are calling
call.addNamedArgument("JOB_ID", "JOB_ID_I");
call.addNamedArgumentValue("JOB_ID", jobId);
You should call the first statement to indicate you will be adding in a "JOB_ID_I" argument to the query, or the second statement to add the value directly to the call, but not both. Calling both indicates your procedure is expecting two parameters called "JOB_ID" and you will get an exception if you do not define the "JOB_ID_I" argument on the query and pass in a parameter for it.
TopLink does not currently create Oracle objects such as Structs and VARRAYs for you from java objects - atleast not for stored procedures arguments, as it does not know how or what to convert them to. You will need to create the Oracle object type yourself, and pass it into the query. I have not tested it, but it would look something like:
UnitOfWork unitOfWork = getUnitOfWork();
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("DSM_JOB_PKG.INSERT_JOB_RUN_LOG");
String jobId = jobIdItr.next().toString();
call.addNamedArgumentValue("JOB_ID_I", jobId);
Timestamp sysdate = BeanConvertUtil.getCurrentTimestamp();
call.addNamedArgumentValue("ORDER_DATE_I", sysdate);
call.addNamedArgumentValue("USER_ID_I", userId);
Connection con = getSession().getAccessor().getConnection();
oracle.sql.ArrayDescriptor anArrayDescriptor = new oracle.sql.ArrayDescriptor("GENERIC_STRING_TYPE",con);
oracle.sql.ARRAY anARRAYin = new ARRAY(anArrayDescriptor, con, paramTypeIds );
call.addNamedArgumentValue("JOB_PARAM_TYPE_IDS_I", anARRAYin );
oracle.sql.ARRAY anARRAYin2 = new ARRAY(anArrayDescriptor, con, paramValues);
call.addNamedArgumentValue("JOB_PARAM_VALUES_I", anARRAYin2 );
session.executeSelectingCall(call);

How to update Oracle Client

Hey,
I downloaded and installed the Oracle Client Version 10.2.0.1 on Windows x86
Now I would like to update this oracle client, but how ?
I installed the software to
C:\oracle\client
Now I downloaded Patchset 3 (10.2.0.4)
But I can´t install this patchset, because I can´t select the folder c:\oracle\client --> OUI-10136: OracleHome already exists
But thats the home I need to update, right ?
How to update the oracle client software ?
Is there any full package to download for version 10.2.0.4 ?

Absolut weird.
I can´t use the drop down menu.
It looks like disabled.
But acutually you can (and have to) click on the little arrow, pick the default value and then the installation works.
Thanks a lot
