1.首先設置要創建的ORACLE的SID，如果在.bash_profile文件裏設置裏該變量，就不用設置了。
$echo $ORACEL_SID
mdy
如果沒有設置，就手動設置，如果壹個服務器上要運行多個ORACLE實例，也需要手動設置。
export ORACLE_SID=gcm
2. 創建需要的診斷目錄，這些目錄都是ORACLE進程遇到錯誤或用戶手動TRACE時需要的。
mkdir -p $ORACLE_BASE/admin/gcm/adump
mkdir -p $ORACLE_BASE/admin/gcm/bdump
mkdir -p $ORACLE_BASE/admin/gcm/cdump
mkdir -p $ORACLE_BASE/admin/gcm/udump
mkdir -p $ORACLE_BASE/admin/gcm/pfile
創建oracle的數據文件目錄
mkdir -p $ORACLE_BASE/oradata/gcm
3. 創建ORACLE的參數文件$ORACLE_HOME/dbs/initgcm.ora 內容如下：
aq_tm_processes=0
audit_file_dest=/oracle/admin/gcm/adump
background_dump_dest=/oracle/admin/gcm/bdump
compatible=10.2.0.1.0
control_files=/oracle/oradata/gcm/control01.ctl, /oracle/oradata/gcm/control02.ctl, /oracle/oradata/gcm/control03.ctl
core_dump_dest=/oracle/admin/gcm/cdump
db_block_size=8192
db_domain=""
db_file_multiblock_read_count=16
db_name=gcm
instance_name=gcm
dispatchers="(PROTOCOL=TCP) (SERVICE=gcmXDB)"
job_queue_processes=10
nls_length_semantics=BYTE
open_cursors=300
pga_aggregate_target=94371840
processes=150
remote_login_passwordfile=EXCLUSIVE
resource_manager_plan=""
sessions=170
sga_target=285212672
undo_management=AUTO
undo_retention=900
undo_tablespace=UNDOTBS1
user_dump_dest=/oracle/admin/gcm/udump
4.創建密碼文件
orapwd file=$ORACLE_HOME/dbs/orapwgcm password=admin entries=5 force=y
5.創建oracle的建庫腳本 createdb.sql,內容如下：
create database gcm
MAXINSTANCES 1
MAXLOGHISTORY 1
MAXLOGFILES 5
MAXLOGMEMBERS 5
MAXDATAFILES 100
DATAFILE
'/oracle/oradata/gcm/system01.dbf' size 100m reuse autoextend on next 1m maxsize unlimited extent management local
sysaux datafile
'/oracle/oradata/gcm/sysaux01.dbf' size 100m reuse autoextend on next 1m maxsize unlimited
default temporary tablespace TEMP tempfile
'/oracle/oradata/gcm/temp01.dbf' size 20m reuse autoextend on next 640k maxsize unlimited
undo tablespace UNDOTBS1 datafile
'/oracle/oradata/gcm/undo01.dbf' size 20m reuse autoextend on next 5M maxsize unlimited
logfile
GROUP 1 ('/oracle/oradata/gcm/redo1.dbf') size 10m,
GROUP 2 ('/oracle/oradata/gcm/redo2.dbf') size 10m,
GROUP 3 ('/oracle/oradata/gcm/redo3.dbf') size 10m
CHARACTER SET ZHS16GBK
NATIONAL CHARACTER SET AL16UTF16
6.數據庫創建完成後，再創建ORACLE的數據字典。
SQL>@/oracle/product/10g/rdbms/admin/catalog.sql
SQL>@/oracle/product/10g/rdbms/admin/catproc.sql
SQL>@/oracle/product/10g/rdbms/admin/catexp.sql
到此ORACLE手動創建過程就完成了
7.創建（新）用戶：
create user gcm identified by onewavegcm;
username：新用戶名的用戶名
password: 新用戶的密碼
也可以不創建新用戶，而仍然用以前的用戶，如：繼續利用scott用戶
8.創建表空間：
create tablespace gcm datafile 'd:\data.dbf' size 300m;
tablespacename：表空間的名字
d:\data.dbf'：表空間的存儲位置
xxx表空間的大小，m單位為兆(M)
9.將空間分配給用戶：
alter user gcm default tablespace gcm;
將名字為tablespacename的表空間分配給username
10.給用戶授權：
grant connect,resource,dba to gcm;
11.然後再以樓主自己創建的用戶登錄，登錄之後創建表即可。
conn username/password;
創建表用create table.
SELECT host_name, instance_name, version FROM v$instance;
select distinct username from v$session ;
imp gcm/onewavegcm file=gcmtable.dmp full=y
12.修改監聽配置文件listener.ora
gcm =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 219.141.133.x)(PORT = 1522))
)
)
)
SID_LIST_gcm =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = gcm)
(ORACLE_HOME = /oracle/product/10g)
(SID_NAME = gcm)
)
)
13.啟動實例
su oracle
export ORACLE_SID=boss
sqlplus>startup
exit
su oracle
export ORACLE_SID=gcm
sqlplus / as sysdba
>startup
14.啟動監聽
su oracle
#lsnrctl start #listener1
#lsnrctl start gcm #listener2
