Steps

1. 修改内核

#vi /etc/system
set shmsys:shminfo_shmmax=536870912
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=10
set semsys:seminfo_semmni=110
set semsys:seminfo_semmns=310
2. 创建用户和组

#groupadd dba
#useradd –g dba –d /export/home/oracle –m oracle
#passwd oracle
3.设定oracle用户的环境参数

#su oracle
$vi .profile       
ORACLE_BASE=/export/home/oracle 
ORACLE_HOME=$ORACLE_BASE/product/10.0 
ORACLE_SID=orcl
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK 
PATH=$ORACLE_HOME/bin:/bin:/sbin:/usr/ccs/bin:/usr/local/bin 
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/network/lib:/usr/local/lib:/usr/lib 
TMPDIR=/var/tmp 
DISPLAY=192.168.0.101:0.0
export ORACLE_BASE ORACLE_HOME ORACLE_SID NLS_LANG PATH LD_LIBRARY_PATH  DISPLAY TMPDIR 
umask 022

How to start and stop the Oracle?

Start

1. Start Listener
lsnrctl start

2. Start DB itself.
sqlplus SYS/ADMIN as sysdba

STARTUP spfile="/export/home/oracle/product/10.0/dbs/spfileorcl.ora"

Note, 1. file spfileorcl.ora contains some invalid characters in my installation. I remove them manuall. 
           2. The default pfile file initorcl.ora is not also found there.
           3. In some versions, the spfile is not option for startup, then what you need do is copy spfileorcl.ora initorcl.ora , after that, run startup in sqlplus.

3. Start EM.
emctl start dbconsole

Note, sometimes it fail, please stop it and restart it again.

4. Start isql server.
isqlplusctl start

Stop

1. Shutdown DB.
SHUTDOWN immediate

2. stop tsnlisnter.
snrctl stop”

3. Stop em.
emctl stop dbconsole

4. Stop isqlplus.
isqlplusctl stop
