Wats the use of Listener file in oracle

wats the use of Listener file in oracle.

Hi Rajesh !
The listener.ora file describes the environment within which requests for remote connections are serviced. When the listener process is running on a machine, connection requects are intercepted on the specified ports and passed to the database.
The listener trained to listen on a certain port , passess connections thru' to ORACLE 9i server when they contain proper authentication details.
listener.ora file consists of the following elements:
+ Listener's name
+ Protocol addresses that it is accepting connection requests on
+ Services it is listening for
+ Control parameters
By default, the listener.ora file is located in the $ORACLE_HOME/network/admin directory on UNIX operating systems and the ORACLE_HOME\network\admin directory on Windows NT.
It is possible to configure multiple listeners, each with unique name, in one listener.ora file FYI !!

What's the use of this file?

I found a file with the name [email protected] in $oracle_home/dbs.
I deleted it and my oracle works as usual.
What's the use of this file?
Thanks

I hope you took a backup of that file before zapping it. As a rule, it's a very bad idea to just delete a file in the Oracle directory to see whether anything breaks.
If you had read the documentation you would have discovered that [email protected] is part of the RMAN configuration. So your database will continue to work up until the point you try to use RMAN to recover it. If you don't use RMAN then you probably won't miss that file.

What is the use of SYSAUX Tablespace in Oracle 10G

Dear Experts,
Please Tell me What is the use of SYSAUX Tablespace in Oracle 10G Because
during Web Load Testing It is going to increase countinuosly.Although i am not using this with any tables.
How Can I find out the what is gong on in this.
Can I Remove this tablesspace and other non using Schemas like FLOWS_020100,MDSYS,OUTLN,DIP and TSMSYS etc.

What is SYSAUX?
The SYSAUX tablespace provides storage of non-sys-related tables and indexes that traditionally were placed in the SYSTEM tablespace. For example, the tables and indexes that were previously owned by the system user can now be specified for a SYSAUX tablespace. Unfortunately, Oracle still places the SCOTT schema and the other demonstration schemas in the SYSTEM tablespace. Go figure.
The SYSAUX tablespace is specified with the CREATE DATABASE command. This is demonstrated in the example database creation script in Figure 1.1.
CREATE DATABASE test
MAXINSTANCES 1
MAXLOGHISTORY 1
MAXLOGFILES 5
MAXLOGMEMBERS 3
MAXDATAFILES 100
DATAFILE '/usr/oracle/OraHome1/oradata/aultdb1/test/system01.dbf' SIZE 300M REUSE AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL
SYSAUX DATAFILE '/usr/oracle/OraHome1/oradata/aultdb1/test/sysaux01.dbf' SIZE 120M REUSE AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED
DEFAULT TEMPORARY TABLESPACE TEMP TEMPFILE '/usr/oracle/OraHome1/oradata/aultdb1/test/temp01.dbf' SIZE 20M REUSE AUTOEXTEND ON NEXT 640K MAXSIZE UNLIMITED EXTENT MANAGEMENT LOCAL

GROUP 3 ('/usr/oracle/OraHome1/oradata/aultdb1/test/redo03.log') SIZE 10240K
USER SYS IDENTIFIED BY "password" USER SYSTEM IDENTIFIED BY "password";
Oracle10g sysaux
With the new SYSAUX tablespace, Oracle comes closer to providing all the needed tablespaces for a truly OFA-compliant database right out of the box. With just one CREATE DATABASE command we can specify the SYSTEM tablespace, the TEMPORARY tablespace, the AUXSYS tablespace, the default UNDO tablespace, and the redo logs.
Of course, with the Oracle Managed Files option you can create an entire database with a single command, but the database created is not suitable for production use and is not OFA-compliant.
The SYSAUX tablespace is required in all new 10g databases. Only the SYSAUX tablespace datafile location is specified. Oracle specifies the remainder of the tablespace properties including:
online
permanent
read write
extent managment local
segment space management auto
If a datafile is specified for the SYSTEM tablespace, then one must be specified for the SYSAUX tablespace as well. If one is not specified, then the CREATE DATABASE command will fail. The only exception is for an Oracle Managed File system.
During any update of a database to Oracle Database 10g, a SYSAUX tablespace must be created or the upgrade will fail. The SYSAUX tablespace has the same security profile as the SYSTEM tablespace. However, loss of the SYSAUX tablespace will not result in a database crash, only the functional loss of the schemas it contains.
Can I drop SysAux?

Just add for example in a banking application at the end of each paragraph

How to UpLoad the Diffent type of files Through Oracle Pl/Sql...?

Hi TOM,
I want one reusable component to be developed, My requirement is as follows...
We get .CSV,.XML,.DOC.PDF files on the N/w drive. One Batch Job will be running every night and this job should upload all the files present in that N/w drive to the database (Each File should be stored in one row with unique ID) and after loading of each file is done , move the uploaded file to the backup directory.
Note : Average file size is 10-15 MB.
Loading of files in database should be done only using Oracle procedure/function.
Already return this process in Pro*C. But I don't know How to write in Oravle Pl/Sl...?

Yes it can be done. Simply consult the applicable manuals that contains all of the details on how to do it. The manuals are:
- Oracle® Database Application Developer's Guide - Large Objects (refer to Chapter 6 section on Using PL/SQL (DBMS_LOB Package) to Work with LOBs)
- Oracle® Database PL/SQL Packages and Types Reference (refer to the chapter on DBMS_LOB)

Find out the name of parameter file while oracle is running

can any one please tell me how can i find the name of oracle parameter file while oracle is running, i mean is there any parameter that specifies this thing, or is there any data dictionary view
second thing i want to change the default database i mean istead of starting the default database at startup the oracle should start the database that i specify,
i would be greatfull if any one could answer my questions

Ok, so you're running with SPFILE in default location. The file you speak about is used during the database create phase.
Just having a look at the file:
c:\oracle\admin\orcl\pfile\init.ora.1142006183316I can say that:
. The SID is ORCL
. You used DBCA to create the database
. DBCA started creating the database: Saturday 11 of February 2006 at 18:33
This file is used by the DBCA because when you create a database, you must have a parameter file in order to start the instance. This file is easily created as a text file (PFILE) first, then the instance is started. Once the database creation is over, the SPFILE is created from this PFILE. If you check the database create logs (in the %ORACLE_BASE%\admin\ORCL\* directory) you'll see a "CREATE SPFILE FROM PFILE" is ran after the database creation, or before, it depends, and the instance restarted in order for it to use the newly created SPFILE. After that, this file is useless.

What is the use of XML file in EJB

Hi,
Generally EJB contains
1) Home Interface
2) Remote Interface
3) Bean class
4) XMl file
In xml file we will mention something like
<home>name of home interface </home>
<remote?name of remote interface</remote>
what is the use of this xml file and how it works.
Thanks.

It's called the deployment descriptor and it's used by the container to support your bean's configuration. For instance, if you want container managed persistence for an entity bean then you need to tell the container which table to use in which database with the column mappings, etc.

What is the use of properites file

what is the use of properites file

Hi there
Usally a program has some variables that the user can set.
These variables are then saved in a file.
The Property class can read these files and search for special keys in that file for example
Lets say that the program that you have developed
can change its background color.
the user sets the color to pink
and the program stores the valu in the property file.
then the property file entry could look like this
color = pink
On windows systems this is verry much like the ini files if you are familiar with these. (I think allmost any OS has something similair)
In JDK 1.4 there is a new system for dealing with property files. This new class is storing the attributes directly to the register on the os
