二、Oracle 集群软件资源的手工注册
1. 注销crs本身自带的ons、gsd、vip资源
root@rac01 # crs_stop -all
Attempting to stop `ora.rac01.gsd` on member `rac01`
Attempting to stop `ora.rac01.ons` on member `rac01`
Attempting to stop `ora.rac02.gsd` on member `rac02`
Attempting to stop `ora.rac02.ons` on member `rac02`
Stop of `ora.rac02.gsd` on member `rac02` succeeded.
Stop of `ora.rac02.ons` on member `rac02` succeeded.
Stop of `ora.rac01.gsd` on member `rac01` succeeded.
Stop of `ora.rac01.ons` on member `rac01` succeeded.
Attempting to stop `ora.rac01.vip` on member `rac01`
Attempting to stop `ora.rac02.vip` on member `rac02`
Stop of `ora.rac02.vip` on member `rac02` succeeded.
Stop of `ora.rac01.vip` on member `rac01` succeeded.
root@rac01 # crs_unregister ora.rac01.gsd
root@rac01 # crs_unregister ora.rac01.ons
root@rac01 # crs_unregister ora.rac01.vip
root@rac01 # crs_unregister ora.rac02.vip
root@rac01 # crs_unregister ora.rac02.ons
root@rac01 # crs_unregister ora.rac02.gsd
root@rac01 # crs_stat -t
CRS-0202: No resources are registered.
2.创建虚拟IP资源:
root@rac01 # crs_profile -create havip -t application -a /oracle/crs/bin/usrvip \
-o oi=e1000g0,ov=10.198.94.139,on=255.255.248.0
root@rac01 # crs_register havip
root@rac01 # crs_setperm havip -o root
root@rac01 # crs_setperm havip -u user:oracle:r-x
root@rac01 # crs_stat -t -v
Name Type R/RA F/FT Target State Host
----------------------------------------------------------------------
ha_vip application 0/1 0/0 OFFLINE OFFLINE
root@rac01 # crs_start havip
root@rac01 # crs_stat -t -v
Name Type R/RA F/FT Target State Host
----------------------------------------------------------------------
havip application 0/1 0/0 ONLINE ONLINE rac01
3.准备控制其他资源启动、关闭、检查的脚本文件dg.sh/fs.sh/db.sh/lsnr.sh
这四个脚本文件内容参考“五-3/4/5/6”部分
对crs_profile命令中的选项和参数做简单说明:
(1) 选项-r定义了该资源所依赖的资源,在下面的例子中,资源oradata_mount启动时依赖于
disk_group先 启动,需要停止disk_group的时候必须先停止资源oradata_mount,
资源orcl_db的启动则同时依赖于oradata_mount/disk_group/havip/listener;
(2) 参数-o 包括:ci的意思是crs对资源状态的监测间隔(check interval),单位为秒;
ra : crs重启资源的尝试次数,RESTART_ATTEMPTS,次数到达以后将重新分配;
fi : 资源状态出现错误以后,crs的尝试间隔,FAILURE_INTERVAL,单位是秒;
ft : 资源状态出现错误以后,crs的尝试次数,FAILURE_THRESHOLD;
这些参数可以使用默认值,分别是60秒/1/0秒/0。
(3) 参数-a 是指ACTION_SCRIPT,参数值为资源启动、关闭、监测的脚本,脚本固定的三个参数为
start/stop/check;
管理数据库监听的部分:
修改$ORACLE_HOME/network/admin/listener.ora文件,
将其中(HOST = rac01 )部分修改成(HOST = 10.198.94.139 ) (虚拟IP地址)
crs_profile -create listener -t application -a /oracle/crs/crs/public/lsnr.sh -r havip -o \
ci=180,ra=6,ft=2,fi=12
crs_register listener
crs_setperm listener -o root
crs_setperm listener -u user:oracle:r-x
crs_start listener
管理磁盘组和逻辑卷的部分:
crs_profile -create disk_group -t application -a /oracle/crs/crs/public/dg.sh -r havip -o \
ci=180,ra=6,ft=2,fi=12
crs_register disk_group
crs_setperm disk_group -o root
crs_setperm disk_group -u user:oracle:r-x
注:本身磁盘组的启动并不依赖于虚拟IP的启动,这里之所以设置两者的依赖关系,
是为了防止虚拟IP在一个节点启动,而磁盘组在另外一个节点启动,造成资源不一致的情况出现。
管理文件系统的部分:
crs_profile -create oradata_mount -t application -a /oracle/crs/crs/public/fs.sh -r disk_group -o \
ci=180,ra=6,ft=2,fi=12
crs_register oradata_mount
crs_setperm oradata_mount -o root
crs_setperm oradata_mount -u user:oracle:r-x
管理数据库实例的部分:
crs_profile -create orcl_db -t application -a /oracle/crs/crs/public/db.sh -r \
"oradata_mount listener" -o ci=180,ra=6,ft=2,fi=12
crs_register orcl_db
crs_setperm orcl_db -o root
crs_setperm orcl_db -u user:oracle:r-x
crs_start orcl_db
4.确保脚本具有执行属性,并把public 和profile的内容拷到第二个节点上。
# chmod +x /oracle/crs/crs/public/*
# rcp -r -p /oracle/crs/crs/public/* rac02:/oracle/crs/crs/public/
5.启动所有的资源
下面可以看到,在crs启动和关闭资源的过程中,其顺序是按照前面定义的资源依赖关系进行的:
root@rac01 # crs_stop -all
Attempting to stop `orcl_db` on member `rac01`
Stop of `orcl_db` on member `rac01` succeeded.
Attempting to stop `oradata_mount` on member `rac01`
Stop of `oradata_mount` on member `rac01` succeeded.
Attempting to stop `disk_group` on member `rac01`
Stop of `disk_group` on member `rac01` succeeded.
Attempting to stop `listener` on member `rac01`
Stop of `listener` on member `rac01` succeeded.
Attempting to stop `havip` on member `rac01`
Stop of `havip` on member `rac01` succeeded.
root@rac01 # crs_start -all
Attempting to start `havip` on member `rac01`
Start of `havip` on member `rac01` succeeded.
Attempting to start `listener` on member `rac01`
Start of `listener` on member `rac01` succeeded.
Attempting to start `disk_group` on member `rac01`
Start of `disk_group` on member `rac01` succeeded.
Attempting to start `oradata_mount` on member `rac01`
Start of `oradata_mount` on member `rac01` succeeded.
Attempting to start `orcl_db` on member `rac01`
Start of `orcl_db` on member `rac01` succeeded.
检查资源状态是否正常:
oracle@rac01 $ crs_stat -t
Name Type Target State Host

havip application ONLINE ONLINE rac01
