ASM学习笔记_ASM安装

Refer to the <> for your operating system for details on installing ASM.

1 ASM’s installtion can be done by DBCA.

2 如果是非RAC环境下使用ASM, 需要在安装ASM之前用脚本$ORACLE_HOME/bin/localconfig add 启动CSS服务

CSS服务在单实例下的作用还有待确认?

只需启动CSS服务,用来实现ASM实例与RDBMS实例之间的通信
The Cluster Synchronization Services (CSS) daemon is required to enable synchronization between ASM and its client

database instances.

Oracle> su - root
password: xxxx

# /opt/oracle/product/10gr2/bin/localconfig delete
Stopping CSSD.
Unable to communicate with the CSS daemon.
Shutdown has begun. The daemons should exit soon.

#/opt/oracle/product/10gr2/bin/localconfig add

/etc/oracle does not exist. Creating it now.
Successfully accumulated necessary OCR keys.
Creating OCR keys for user 'root', privgrp 'root'..
Operation successful.
Configuration for local CSS has been initialized

Adding to inittab
Startup will be queued to init within 90 seconds.
Checking the status of new Oracle init process...
Expecting the CRS daemons to be up within 600 seconds.

...........

Giving up: Oracle CSS stack appears NOT to be running.
Oracle CSS service would not start as installed
Automatic Storage Management(ASM) cannot be used until Oracle CSS service is starte

启动不了

查看/opt/oracle/product/10gr2/log/z810/client/css.log
[ CSSCLNT][2550264832]clsssInitNative: connect failed, rc 9

运行DBCA过程中报如下错误
Oracle> $ORACLE_HOME/bin/dbca

报错:ORA-29701:Unable to connect to Cluster Manager

单实例下如何启动CRS,CSS,EVM
/etc/init.d/start crs
/etc/init.d/start css
/etc/init.d/start evm

Oracle@Z810:/opt/oracle/product/10gr2/bin/crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM

Oracle@Z810:/opt/oracle/product/10gr2/bin/crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly

Oracle@Z810:/opt/oracle/product/10gr2/bin/crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM

启动不了

在尝试了n次后终于成功了
可能的问题

1 由于在同一个节点上安装了两个Oracl版本:9i,10g.有两个ORACLE_HOME,造成混乱
在有多个ORACLE_HOME的环境下,似乎可以通过/opt/oracle/product/10gr2/bin/localconfig reset来设置环境变量
/opt/oracle/product/10gr2/bin/localconfig  $ORACLE_HOME
是这样吗? 尝试几次都未能成功

2 每尝试一次前应先将LISTENER与各个后台进程建立连接的IPC Socket临时文件删除
rm -f /var/tmp/.oracle/*
rm -f /tmp/.oracle/*
rm -f /usr/tmp/.oracle/*

3 启动监听

4 /opt/oracle/product/10gr2/bin/localconfig add
Successfully accumulated necessary OCR keys.
Creating OCR keys for user 'root', privgrp 'root'..
Operation successful.
Configuration for local CSS has been initialized

Adding to inittab
Startup will be queued to init within 90 seconds.
Checking the status of new Oracle init process...
Expecting the CRS daemons to be up within 600 seconds.
CSS is active on these nodes.
        z810
CSS is active on all nodes.
Oracle CSS service is installed and running under init(1M)

5 oracle@Z810:/var/tmp/.oracle> /opt/oracle/product/10gr2/bin/crsctl check crs

CSS appears healthy
Cannot communicate with CRS
Cannot communicate with EVM
