Difference Between Oracle Database Server And Client?
Jul 22, 2011
Currently I am doing one Oracle installation.But very much confused where to start from. Since I am installing oracle on my personaly Laptop,do I need to install Oracle database server and Oracle client both or only installing database server is sufficient.
What is the exact difference between oracle database server and client.Only knowledge I have is that client is used to access database server remotely.are Oracle database server and client installable to be downloaded separately?

I've a question regarding difference of character sets, while taking a export(logical backup) of database on directly to server(linux RHEL 2.1 AS) and export on a client (windows xp prof machine, where only a oracle 9i client is installed). On server it seems to fine and okay, but on client node i'm getting following error for almost all tables.
EXP-00091: Exporting questionable statistics.
My question is :
[1] Is it creating any sort of problem, if later on i import the data which was taken from client node.
[2] Why there is a difference(marginal) in dump(.dmp) file size.
[3] Is there any way to overcome it, or it is the natural behave of it. Means not a problem.
[4] If i'm using a long or blob as datatype for some of my table,is they have any problem if i persist like above.
Additional Information about character sets On server node :
Export done in US7ASCII character set and AL16UTF16 NCHAR character set server uses WE8ISO8859P1 character set (possible charset conversion)
On client node :
Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set server uses US7ASCII character set (possible charset conversion)

I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server.
2. I invoked "sqlplus" from another unix box to login to the database.
3. I found that the process id (ps -ef |grep sqlplus).
4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID,
SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM,
SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID
FROM
SYS.GV_$PROCESS, SYS.GV_$SESSION
WHERE
SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST'
and SYS.GV_$SESSION.MACHINE like '%hostname%'

what would be the settings on my home's computer for the same. i mean tnsname.ora file or any other setting.

I have installed Oracle 10gR2 database server recently in the Windows box. The database works fine. But I am unable to connect through the Internet Explorer. I found that the service for the isqlplus is not available. Do I need to run any script for creating the service?

I have new virtual UNIX machine and I installed oracle client on /usr/lib/oracle. Also I have a oracle database and I am able to connect to this database from my desktop sql developer.
So now I am trying to connect from new UNIX machine. Where I created tnsnames.ora file under /usr/lib/oracle/network/admin and before connecting did export the following
export TNS_ADMIN=/usr/lib/oracle/network/admin
export ORACLE_HOME=/usr/lib/oracle/
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$PATH:$HOME/bin:/sbin:$ORACLE_HOME/bin
export ORACLE_SID=VFIODSD1
when I try
# sqlplus
username :xxxxxxx
password : xxxxxxx
ORA-12545: Connect failed because target host or object does not exist. Not sure what I missed here. using same tns file I am able to connect from sql developer on windows.

I want to know what is the difference between the file catproc that we run after creation of the database in the Oracle 9i,10g and 11g r2. I have run that file in 11g R2 but it is taking more time and more over there are many new things that i saw in 11g R2 than what were there in 9i and 10g.

difference between a user and schema on Oracle.By difference, I do not mean what is a user and what is a schema.
I understand that if we create a user, the schema gets created by default for that user. Does that mean that we cannot create a user/schema alone.
What if I just want to create a user and grant him some read access on an existing schema or just want to create a schema.

I've migrated from Oracle 9i to Oracle 11gR2, when i'm checking my application on Oracle 11gR2, i found that some of the query result are differed from the previous version of Oracle 9i, which is very illogical to me. I've checked the data for all related tables which are involved in one of the query. I've checked all indexes also. Still i'm not convinced that Oracle is doing anything wrong. I cannot recreate the whole scenario here, because of many tables involved in that query.
One of the sample query code.
select 'ProductMaster' producttype,e.schemecd,e.SCHEMESHORTDESC as SCHEMEDESC,to_char(e.schemefrdate,'dd/MM/yyyy')as schemefrdate, to_char(e.schemetodate,'dd/MM/yyyy') as schemetodate,e.mkid ,e.countrycd,e.statecd,e.districtcd,f.schemetype, a.productcd,a.packsizecd,a.packtypecd,a.sortorder1, a.countrycd,a.statecd,a.districtcd,a.p_uniqueid,a.mrp, (a.productcd ||'-'||b.countryname||'-'||c.statename||'-'||d.districtname|| ' -pkt.prc:'||a.pktprice ||' -mrp:'||a.mrp) as pcode

We are having major differences in performance when accessing an Oracle 11gR2 database from two different environments.
I won't sadden you with the gory details of the full application but I will use an indicative example of our problem.
We have SQL Developer in both environments. In each of these SQL Developer instances is a defined a connection to the same database on another machine. So there is the PC looking at a database and a virtual instance looking at the same database.
Selecting the '+' sign next to 'tables' for that connection, on the PC the list of four tables comes back in 4 seconds but on the virtual instance the list of the same four tables comes back in 1 minute and 50 seconds.
This sort of timing issue is repeatable for all accesses to the Oracle database on the third machine.

I have a Client Server application that I created using an MS-SQL Server Database (MS-SQL Server 2008 R2 Express).Since MS-SQL Server has wide range (and number) of DATA_TYPEs, I elected to dedicate a few of those DATA_TYPEs to application-specific processing (mainly the MONEY and BOOLEAN DATA_TYPES).
I further decided that within the Client Application that the general processing of a particular field would be determined by the corresponding DATA_TYPE stored in the database.
The DATA_TYPE of a particular field within the SQL Server database and may be determined by querying:
"select DATA_TYPE from INFORMATION_SCHEMA.Columns where ( ( Column_name = 'my_Field' ) and ( Table_Name = 'myTable' ) )"
I also extract/use other DATA_TYPE information as needed/appropriate.
With this information the Client Application can consistently process a MONEY (a DATA_TYPE in MS-SQL Server) differently than perhaps either a DECIMAL or a BIGINT (two other DATA_TYPEs in MS-SQL Server). I have to create the field with the correct DATA_TYPE in the database, but after that I don't have to worry about it.
I am now moving over to an Oracle Database (Oracle Database Express Edition 11g Release 2). And I would like to have the same (or similar) functionality as described above.
Oracle has fewer DATA_TYPES so it is more difficult to tie an application-specific-datatype to an Oracle-database-specific-DATA_TYPE. There simply aren't as many to "sacrifice" to my application-specific-processing. I don't want to treat every NUMERIC field as "the-apps-money-type."
With Oracle I can associate "the-apps-money-type" with, let's say, a NUMERIC(9,2) and then the Client Application will treat all NUMERIC(9,2) as "the-apps-money-type."The Client Application queries the Oracle database for DATA_TYPE, DATA_PRECISION, and DATA_SCALE to make this determination.
But this approach does not appeal to me, suppose that I have other NUMERIC(9,2) fields that are not of "the-apps-money-type." How can I set and then later determine, from the Oracle backend, if the NUMERIC(9,2) field is meant to be used as "the-apps-money-type" or just a regular number?
Is there some way I may create some sort of "sub DATA_TYPE" in Oracle?I considered indicating this in the COMMENTS field that is associated with particular field. Then query for that comment when I process NUMERIC DATA_TYPEs. But the COMMENTS field does not seem to make it into user_tab_columns or all_tab_columns.
(With Oracle SQL Developer one can create/modify/delete the user created tables/fields. COMMENTS may be added to particular fields within a table--these are the COMMENTS that I am referring to above).What I would like to do, and most direct approach to me, would be to somehow create a user defined DATA_TYPE that is simply:
1) a user defined DATA_TYPE name (like, MY_MONEY_TYPE),
2) associated with an Oracle Built-in datatype (like NUMERIC(9,2).
Then when the client application queries user_tab_columns the field may be processed appropriately. If I cannot do that, perhaps there is somewhere else that I may set and subsequently query for this sort of information. What is(are) the most direct way(s) to implement the functionality described above?

I'm trying to connect a oracle client application on the client machine to a remote oracle server on the server machine but i get a connection fail.
On the server machine I configured oracle server in the following way:
Installed oracle server. Created a database "DB_Test" with the database configuration assistant Created a LISTNER with the Oracle NET Manager with the following parameter:
Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521 Created "dbtest" service with the Oracle NET Manager with with the following parameter:
Service Name: "dbtest" Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521
All services on the server machine are running and I opened port number (1521) in the router. On the client machine I installed SQL PLUS and SQL Developer.
With SQL Plus as by the official documentation I have entered the following command:
CONNECT username/password@[//]host[:port][/service_name]. In my case is:
CONNECT SYSTEM/oracledb@//ENZOVAIO:1521/testdb.
With SQL Developer I have entered the same parameter.
But with both SQLPlus and SQL Developer the connection fails.

My question is; I've been reading the Oracle database 11g R2 documentation at this link [URL]...
I passed a couple of days learning about all installation configuration parts including the desktop class and server class.As I was learning, So I had already downloaded Oracle Database Express 11g R2 for win32.
So as i had finished the installation guide I thought it's time to install the oracle now. I did it, and what I found was that there was not any option during installation that i read in above documentation. While trying to find about this difference i reached on documentation[URL]...
That is for express version only.
My question here is, Express edition, we use for learning purpose, But it doesn't look like it has all the stuff that we should learn during installation And what documentation I should follow from my above given two links?

I wanted to load some data(selected rows) from one system to other.
from source(production) system Toad: selected * from employee table where registration date is not today.
from data grid I exported the rows using save as (in insert statement format) to employee.sql.
the sql file(employee.sql) has the below values for emaplyee 2,60716197237375E17 in the source(production) system this value is 260716197237375278, Later I loaded the sql file to dev system at linux prompt with sql file
@emplaoyee.sql
I retrieved the data after loading using to_char
select toc_char(emp_code) from employee_t;
the value I got is :260716197237375000
where as my expectation is : 260716197237375000
Is there any configuration required on linux system to convert the data correctly while loading to database using @employee.sql?
To conclude:
Exported value : 260716197237375278 (but exported as 2,60716197237375E17)
After import the value is : 260716197237375000 instead 260716197237375000

on my Windows 7 machine with Oracle Client 12.0.1.0 installed I'm trying to create a database link to a database server, that runs under Oracle Standard Edition1 11.2.0.2. When i login to sqlplus on the client with "sqlplus /nolog" and type the command : SQL> create database link SID connect to user identified by passwd using 'tnsnames.ora connection'; I'm getting an SP2-0640: not logged in.
Ok, thats clear, because i use sqlplus with /nolog option. But on client side normally I have no database, where I can login. So I think, there will be no user, or? The database to which I want to connect is set in tnsnames.ora. Generally: Is it possible to use the Oracle Client to create a database link?
