First enter the .bash_profile file under the ORACLE user
[oracle@linux02 ~]$ vi .bash_profile
export ORACLE_SID=hldb
export ORACLE_UNQNAME=hldb
Change ORACLE_SID and ORACLE_UNQNAME to the new database name
[oracle@linux02 ~]$ source .bash_profile
refresh file
----------------------------------------------------------------------------------------------------------
Enter the /u01/app/oracle/oradata directory
[oracle@linux02 oradata]$ cd /u01/app/oracle/oradata
[oracle@linux02 oradata]$ pwd
/u01/app/oracle/oradata
Create a new folder
[oracle@linux02 oradata]$ mkdir hldb
Go to $ORACLE_HOME/dbs
[oracle@linux02 ~]$ cd $ORACLE_HOME/dbs
create password file
[oracle@linux02 dbs]$ orapwd file=orapwhldb password=oracle
Create a new parameter file and write relevant information
[oracle@linux02 dbs]$ vi inithldb.ora
DB_NAME='hldb'
CONTROL_FILES='/u01/app/oracle/oradata/hldb/control01.ctl'
MEMORY_TARGET=900M
