由于后文会相关的演示操作会用到ASM实例,因此在文章的开始就先创建一个简单的ASM实例,后面再开始详细的介绍ASM。
由于后文会相关的演示操作会用到ASM实例,因此在文章的开始就先创建一个简单的ASM实例,,后面再开始详细的介绍ASM。
下面是创建一个ASM Instance的具体操作过程:
创建ASM实例的相关目录
[Oracle@gtser1~]$ mkdir -p $ORACLE_BASE/admin/+ASM/bdump
[oracle@gtser1~]$ mkdir -p $ORACLE_BASE/admin/+ASM/cdump
[oracle@gtser1~]$ mkdir -p $ORACLE_BASE/admin/+ASM/hdump
[oracle@gtser1~]$ mkdir -p $ORACLE_BASE/admin/+ASM/pfile
[oracle@gtser1~]$ mkdir -p $ORACLE_BASE/admin/+ASM/udump
准备pfile的初始化参数
[oracle@gtser1~]$ vi /tmp/init+ASM.ora
INSTANCE_TYPE=ASM
"/tmp/init+ASM.ora"6L, 225C 已写入
[oracle@gtser1~]$ cat /tmp/init+ASM.ora
INSTANCE_TYPE=ASM
*.instance_name='+ASM'
*.asm_diskstring='/dev/raw/raw*'
background_dump_dest=/u01/oracle/10g/admin/+ASM/bdump
core_dump_dest=/u01/oracle/10g/admin/+ASM/cdump
user_dump_dest=/u01/oracle/10g/admin/+ASM/udump
启动ASM实例
[oracle@gtser1~]$ export ORACLE_SID=+ASM
[oracle@gtser1~]$ sqlplus "/as sysdba"
