gi的参数文件
/u01/app/11.2.0/grid/dbs/init.ora
但是里面的东西不对，因为这个不是asm真正使用的pfile

gi的密码文件
/u01/app/11.2.0/grid/dbs/orapw+ASM

gi的alert文件
/u01/app/grid/diag/asm/+asm/+ASM2/trace/

ASM的SPFIE不能直接cp出来

ASM也有自己的alert文件

OCM考试的时候自己创建了ASM的listener、pfile、passwd文件

oracle用户关掉监听
lsnrctl stop listener
lsnrctl stop lsnr2

grid配置监听，使用oracle用户下的监听文件
/u01/app/11.2.0/grid/bin/srvctl add listener -l listener -p 1521 -o /u01/app/oracle/product/11.2.0/dbhome_1
/u01/app/11.2.0/grid/bin/srvctl add listener -l lsnr2 -p 1526 -o /u01/app/oracle/product/11.2.0/dbhome_1
/u01/app/11.2.0/grid/bin/srvctl start listener -l listener
/u01/app/11.2.0/grid/bin/srvctl start listener -l lsnr2


grid用户配置参数文件
cd /u01/app/11.2.0/grid/dbs
vi init+ASM.ora
instance_type=ASM

grid用户创建密码文件
orapwd file=orapw+ASM password=oracle


sqlplus / as sysasm
startup nomount

CREATE DISKGROUP dg01 EXTERNAL REDUNDANCY DISK '/dev/oracleasm/disks/DISK1';
create diskgroup fra normal redundancy disk 'ORCL:DISK1', 'ORCL:DISL2';
如果失败，则alter system set asm_diskstring='/dev/oracleasm/disks/'否则下面asmcmd lsdsk --candidate显示不出磁盘组
alter diskgroup fra mount;
