linux下 oracle 11g 手工建库

实例名

export ORACLE_SID=mypl

创建文件夹

mkdir /u01/app/oracle/product/admin/adump -p

mkdir /u01/app/oracle/product/admin/bdump -p

mkdir /u01/app/oracle/product/admin/cdump -p

mkdir /u01/app/oracle/product/admin/udump -p

mkdir /u01/app/oracle/product/admin/pfile -p

mkdir /u01/app/oracle/product/admin/create -p

mkdir /u01/app/oracle/oradata/mypl

创建密码文件

orapwd file=/u01/app/oracle/product/11.2.0/dbs/orapwmypl password=oracle;

创建启动实例文件

[root@orale app]# chown -R oracle:oinstall /u01/app/

[root@orale app]# chmod -R 775 /u01/app/ 

[oracle@orale app]$ cat >aaa.ora 

db_name=mypl

control_files=(/u01/app/oracle/oradata/contro01.ctl)

进入SQL创建指定实例启动文件

[oracle@orale app]$  lsnrctl start

[oracle@orale app]$ sqlplus / as sysdba;

SQL>create spfile from pfile='/u01/app/aaa.ora';

File created.

SQL> startup nomount;

ORACLE instance started.

Total System Global Area  146472960 bytes

Database Buffers           50331648 bytes

Redo Buffers                2531328 bytes

执行脚本创建数据库(注下面参数是给虚拟机配置的):

SQL> 

CREATE DATABASE mypl

   USER SYS IDENTIFIED BY oracle

   USER SYSTEM IDENTIFIED BY oracle

   LOGFILE GROUP 1 ('/u01/app/oracle/oradata/mypl/redo01.log') SIZE 50M,

           GROUP 2 ('/u01/app/oracle/oradata/mypl/redo02.log') SIZE 50M,

           GROUP 3 ('/u01/app/oracle/oradata/mypl/redo03.log') SIZE 50M

   MAXLOGFILES 20

   MAXLOGMEMBERS 5

   MAXLOGHISTORY 200

   MAXDATAFILES 100

   CHARACTER SET ZHS16GBK

   NATIONAL CHARACTER SET AL16UTF16

   EXTENT MANAGEMENT LOCAL

   DATAFILE '/u01/app/oracle/oradata/mypl/system01.dbf' SIZE 500M REUSE

   SYSAUX DATAFILE '/u01/app/oracle/oradata/mypl/sysaux01.dbf' SIZE 325M REUSE

   DEFAULT TEMPORARY TABLESPACE temp

      TEMPFILE '/u01/app/oracle/oradata/mypl/temp01.dbf'

      SIZE 20M REUSE

   UNDO TABLESPACE undotbs1

      DATAFILE '/u01/app/oracle/oradata/mypl/undotbs01.dbf'

      SIZE 200M REUSE;

      

 Step 10: Create Additional Tablespaces

SQL> create tablespace users datafile '/u01/app/oracle/oradata/ocm/users01.dbf'  size 50M;

Tablespace created.

SQL> alter database default tablespace users;

Database altered.

执行下面三个脚本(注第三个需要用system用户执行)

SQL> @?/rdbms/admin/catalog.sql
SQL> @?/rdbms/admin/catproc.sql

SQL> @?/sqlplus/admin/pupbld.sql

分配内存

SQL> show parameter db_cache_size

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

db_cache_size                        big integer 48M

gyj@OCM> alter system set sga_max_size=800M scope=spfile;

System altered.

SQL>alter system set sga_max_size=600M scope=spfile;

SQL> shutdown immediate;

SQL> startup

SQL>alter system set db_cache_size=200M;

到这就已经建库完成了

以上的参数及以下均是抄袭的

删除数据库：因使用手工创建的数据库使用DBCA无法删除，此时需要使用命令来删除数据库。

使用以下三个命令即可：
startup mount exclusive
alter system enable restricted session;
drop database;  

数据库相应的控制文件,日志文件，数据文件会自动删除,spfile也会删除(归档日志不会删除). 

手工建库时的ALERT日志

[oracle@bys3 ~]$ find /u01/ -name  alert_*

/u01/app/oracle/diag/rdbms/mypl/mypl/trace/alert_mypl.log

/u01/app/oracle/diag/rdbms/mypl/plocp/trace/alert_plocp.log

[oracle@bys3 ~]$ cat alert_mypl.log
