Setting up Oracle APEX for the first time

Once you are done with installing your Oracle DB instance  ( 11g or 10g )  , the next step is to make sure your Oracle APEX is kick started .


1) Make sure your Oracle Database is up and running .

2) Make sure your default port for the webserver that is (8080) is not occupied by any other product .

3) As the Oracle Database already comes with oracle XML DB and Oracle embedded plsql gateway server , you actually need not bother about configuring the apex  , as APEX uses the embedded plsql gateway as the default Application server .


4) There are many default scripts which comes with oracle apex which can be used for installing , configuring or adminsitrting or customizing the settings of the oracle apex .

       C:\Oracle_home\APEX\    ---- you will find many sql scripts which starts with the apex_version_no_script_description.sql
 EX:-  apxldimg.sql  this is used for loading the images of the application developer of the apex during the apex installation from scratch or it upgradation .


5) One the files is apxconf.sql  , this is used for configuring the APEX   .

When you run this particular command , you will be shown the default port no which is being used or available :- 8080 .

Then  you will be asked to enter the password for the APEX ADMIN :- " enter the password".
Then you need to reneter the password for the confirmation again :  " renter the password " .

Note this password will be the admin password for you default workspace of apex thats nothing but ( Internal ) .

 You will be asked to enter the port , incase you wanna continue with the same default port then u can enter (8080) as you port no ,else you can change for any other .




[oracle@db11gr2 apex]$ cd $ORACLE_HOME/apex
[oracle@db11gr2 apex]$ sqlplus /nolog

Enter values below for the XDB HTTP listener port and the password for the Application Express ADMIN user.
Default values are in brackets [ ].
Press Enter to accept the default value.
Enter a password for the ADMIN user []

 6) Using the Following Comand cross verify whether your  web server is up and running .

SQL> SELECT DBMS_XDB.GETHTTPPORT FROM DUAL;

GETHTTPPORT
-----------
 8080

 You can mak apex down , by runnnig the comman

SQL>EXEC DBMS_XDB.SETHTTPPORT(0);
SQL>EXEC DBMS_XDB.SETHTTPPORT(8080);
again makes the Oracle APEX Up .

7)  Now login into oracle apex instance as

http://localhost:8080/apex/apex_admin

or 

http://localhost:8080/apex 

Workspace:-  Internal 

  User:-  Admin 

Password :- enter admin password .

Now create your development  workspace ,schemas and  users,



8)Incase you wanna use the pdf printing functionality or email fucntionality then you need to run this package , the package exists in the installation document , kindly! go thru it once .
