To take the full database export (Oracle 10g):

Create a Export Directory:
##########################

On Solaris:
-----------
SQL> create or replace directory sys_dmp as '/u02/expdp';
Directory created.

On Windows:
-----------
SQL> create or replace directory sys_dmp as 'D:\expdp';
Directory created.

Create a separate export user:
##############################

SQL> Connect /as sysdba

SQL> CREATE USER expdpadmin IDENTIFIED BY expdp default tablespace users;
User created.

Grant Export and Import Privileges.
###################################

SQL> GRANT CONNECT,RESOURCE TO expdpadmin;
Grant succeeded.

SQL> GRANT exp_full_database to expdpadmin;
Grant succeeded.

SQL> alter user expdpadmin quota unlimited on USERS;
User altered.

SQL> GRANT READ, WRITE ON DIRECTORY SYS_DMP to expdpadmin;
Grant succeeded.

To check on which directories you have privilege to read & write:
#################################################################

SQL> SELECT privilege, directory_name
2 FROM user_tab_privs t, all_directories d
3 WHERE t.table_name(+)=d.directory_name
4 ORDER BY 2,1;

Exporting Full Database:
########################

expdp expdpadmin/XXXXXX full=y directory=sys_dmp dumpfile=full_db_expdp.dmp logfile=full_db_expdp.log

Group and User Creation in Solairs.

This post is for creating an Unix Group and a User.

Solaris 5.10
--------------------------------------
Creating a Group:
--------------------------------------

For instance: Group - dba

Login as ROOT User

login: root
Password:
Sun Microsystems Inc. SunOS 5.10 Generic January 2005
#

To Check whther the group is already created.

# grep dba /etc/group
or
# cat /etc/groupgrep dba

If dba group info is not displayed, then

To create a Group:

# groupadd dba

Syntax: groupadd -g

# cat /etc/groupgrep dba

dba:103:

Note: The gid, which needs to be changed, should be not being the gid of other group.
Example:
# usermod -g 333 dba
UX: groupmod: ERROR: 103 is already in use. Choose another.

To remove a Group:

# groupdel dba

# cat /etc/groupgrep dba

Commands:
---------

Create Group - groupadd
Modify Group - groupmod
Remove Group - groupdel

For more details, check the man pages i.e. man groupadd, man groupmod, and man groupdel

--------------------------------------
Creating a User Account:
--------------------------------------

For instance: User - Oracle

Login as ROOT User

login: root
Password:
Sun Microsystems Inc. SunOS 5.10 Generic January 2005
#

To Check whther the oracle user is already created.

# grep oracle /etc/passwd
Or
# id –a oracle

If Oracle group info is not displayed, then

To create a User:

# useradd –d /export/home/oracle –m -g dba -s /bin/sh oracle


Note: In the above command
Option -Discription -Value
------------- -------------------- --------------------
-d -Home for the Oracle user -/export/home/oracle
-m -For making directory
-g -Primary Group dba
-s -Default Shell for the User -/bin/sh
Login -Name -Oracle

# grep oracle /etc/passwd
oracle:x:100:100::/export/home0/oracle:/bin/sh

To modify a User:

For example: To Comment the user and assing secondray group to the user

# usermod -c "Owner of the Oracle Software 10g" -G oinstall oracle

Note: In the above command
Option -Discription -Value
------------- -------------------- --------------------
-c -Comment -"Owner of the Oracle Software"
-G -econdary -Group oinstall


# grep oracle /etc/passwd
oracle:x:100:100:Owner of the Oracle Software 10g:/export/home0/oracle:/bin/sh

To set a password:

# passwd -r files oracle
New Password: XXXXXXXX
Re-enter new Password: XXXXXXXX
passwd: password successfully changed for oracle

Note: Where XXXXXXXX is the new password for oracle User.

To remove a user:

# userdel -r oracle

Note: The "-r" option is used to remove the user's home directory from the system.
And the Oracle user account should not be removed until and unles required, and
this should not be done on Production Servers.

# grep oracle /etc/passwd


Commands:
---------
Create a user - useradd
Modify a user - usermod
Rmove a user - userdel

seta password to the user- passwd

For more details, please check the man pages in UNIX i.e. man useradd, man usermod, and man userdel
