Oracle RAC数据库个别资源不能自动启动

 最近处理过好几个关于RAC在重启时个别资源无法启动，例instance、tns 等。

资源情况如下：

ora.CRS.dg

ora.LISTENER_SCAN1.lsnr

      1        ONLINE  ONLINE       resdb1                                       

ora.cvu

      1        ONLINE  ONLINE       resdb2                                      

ora.oc4j

      1        ONLINE  ONLINE       resdb1                                      

ora.resdb.db

      1        OFFLINE OFFLINE       resdb1                                  

      2        OFFLINE OFFLINE       resdb2     

 

从上面状态信息可以看出，resdb数据库的resdb1和resdb2两个实例及监听的TARGET和STATE值都为OFFLINE。

  而大多数初级DBA在关闭数据库和监听是基本都是sqlplus shut immediate，这样以来就会出现上边的问题。（这样会导致cluster 无法正常管理资源）

查看

查看每个资源属性的值如下：

NAME=ora.LISTENER.lsnr

TYPE=ora.listener.type

ACL=owner:grid:rwx,pgrp:oinstall:rwx,other::r--

ACTION_FAILURE_TEMPLATE=

ACTION_SCRIPT=%CRS_HOME%/bin/racgwrap%CRS_SCRIPT_SUFFIX%

AGENT_FILENAME=%CRS_HOME%/bin/oraagent%CRS_EXE_SUFFIX%

ALIAS_NAME=ora.%CRS_CSS_NODENAME_LOWER_CASE%.LISTENER_%CRS_CSS_NODENAME_UPPER_CASE%.lsnr

AUTO_START=restore----此属性

CHECK_INTERVAL=60

CHECK_TIMEOUT=120

DEFAULT_TEMPLATE=PROPERTY(RESOURCE_CLASS=listener) PROPERTY(LISTENER_NAME=PARSE(%NAME%, ., 2))

DEGREE=1

DESCRIPTION=Oracle Listener resource

ENABLED=1

ENDPOINTS=TCP:1521

LOAD=1

LOGGING_LEVEL=1

NAME=ora.resdb.db

TYPE=ora.database.type

ACL=owner:oracle:rwx,pgrp:oinstall:r--,other::r--,group:dba:r-x,group:oper:r-x,user:grid:r-x

ACTION_FAILURE_TEMPLATE=

ACTION_SCRIPT=

ACTIVE_PLACEMENT=1

AGENT_FILENAME=%CRS_HOME%/bin/oraagent%CRS_EXE_SUFFIX%

AUTO_START=restore----此属性

CARDINALITY=2

CHECK_INTERVAL=1

CHECK_TIMEOUT=30

CLUSTER_DATABASE=true

避免此问题发生，可修改如下属性：（root用户）

./crsctl modify resource "ora.LISTENER.lsnr" -attr "AUTO_START=always"

./crsctl modify resource "ora.resdb.db" -attr "AUTO_START=always"

而10G数据库的crs和11G还是有一定差别的。

10G 的属性如下：

$ crs_stat -p

NAME=ora.dba.LISTENER_RACDB1.lsnr

TYPE=application

ACTION_SCRIPT=/oracle/oracle10g/bin/racgwrap

ACTIVE_PLACEMENT=0

AUTO_START=1

CHECK_INTERVAL=600

.......

NAME=ora.dbb.LISTENER_RACDB2.lsnr

TYPE=application

ACTION_SCRIPT=/oracle/oracle10g/bin/racgwrap

ACTIVE_PLACEMENT=0

AUTO_START=1

CHECK_INTERVAL=600

DESCRIPTION=CRS application for listener on node

NAME=ora.RACDB.db

TYPE=application

ACTION_SCRIPT=/oracle/crs10g/bin/racgwrap

ACTIVE_PLACEMENT=0

AUTO_START=1

CHECK_INTERVAL=600

NAME=ora.RACDB.RACDB1.inst

TYPE=application

ACTION_SCRIPT=/oracle/oracle10g/bin/racgwrap

ACTIVE_PLACEMENT=0

AUTO_START=1

NAME=ora.RACDB.RACDB2.inst

TYPE=application

ACTION_SCRIPT=/oracle/oracle10g/bin/racgwrap

ACTIVE_PLACEMENT=0

AUTO_START=1

属性说明：

AUTO_START值

0，表示：启动到资源重启之前的状态
1，表示: 启动资源
2，表示：不启动资源

可以用如下命令进行修改

crs_register resource_name -update -o as=2  ---（root下）

一般在安装11GR2 RAC时，有经验的dba都会对资源属性进行修改

如：

./crsctl modify res ora.crf -attr AUTO_START=never

./crsctl modify res ora.crf ENABLE=0 –init

./crsctl modify resource "ora.LISTENER.lsnr" -attr "AUTO_START=always"

./crsctl modify resource "ora.racdb.db" -attr "AUTO_START=always"
