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/

sqlplus / as sysasm

SQL> show parameter pfile

ASM的SPFIE不能直接cp出来

ASMCMD> cp +DATA/plmdb-cluster/asmparameterfile/registry.253.947607045 /home/grid/

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;
