• Oracle RAC 日常基本维护命令


    列出配置的所有数据库

    [root@node1 ~]# srvctl config database
    NOVADB

    所有实例和服务的状态

    [root@node1 ~]# srvctl status database -d NOVADB
    Instance NOVADB1 is running on node node1
    Instance NOVADB2 is running on node node2

    单个实例的状态

    [root@node1 ~]# srvctl status instance -d NOVADB -i NOVADB1
    Instance NOVADB1 is running on node node1

    在数据库全局命名服务的状态

    $ srvctl status service -d orcl -s orcltest
    Service orcltest is running on instance(s) orcl2, orcl1

    显示指定集群数据库的所有服务

    [root@node1 ~]# srvctl config service -d NOVADB
    NOVADB PREF: NOVADB1 NOVADB2 AVAIL:

    显示节点应用程序的配置 —(VIP、GSD、ONS、监听器)

    [root@node1 ~]# srvctl config nodeapps -n node1 -a -g -s -l
    VIP exists.: /node1-vip/192.168.150.224/255.255.255.0/eth0
    GSD exists.
    ONS daemon exists.
    Listener exists.

    利用srvctl config命令可以看到现有数据库的配置信息:

    [root@node1 ~]# srvctl config database -d NOVADB -a
    node1 NOVADB1 /opt/ora10g/product/10.2.0/db_1
    node2 NOVADB2 /opt/ora10g/product/10.2.0/db_1
    DB_NAME: NOVADB
    ORACLE_HOME: /opt/ora10g/product/10.2.0/db_1
    SPFILE: +RAC_DISK/NOVADB/spfileNOVADB.ora
    DOMAIN: null
    DB_ROLE: null
    START_OPTIONS: null
    POLICY: AUTOMATIC
    ENABLE FLAG: DB ENABLED

    显示 ASM 实例的配置

    [root@node1 ~]# srvctl config asm -n node1
    +ASM1 /opt/ora10g/product/10.2.0/db_1
    [root@node1 ~]# srvctl config asm -n node2
    +ASM2 /opt/ora10g/product/10.2.0/db_1

    ORCL:NOVA3

    启动/停止RAC集群

    确保是以 oracle UNIX 用户登录的。我们将从rac1节点运行所有命令:

    # su – oracle

    [oracle@node1 ~]$ hostname

    node1

    停止 Oracle RAC 10g 环境

    第一步是停止 Oracle 实例。当此实例(和相关服务)关闭后,关闭 ASM 实例。最后,关闭节点应用程序(虚拟 IP、GSD、TNS 监听器和 ONS)。

    [oracle@node1 ~]$ export ORACLE_SID=NOVADB1
    [oracle@node1 ~]$ emctl stop dbconsole
    [oracle@node1 ~]$ srvctl stop instance -d NOVADB -i NOVADB1
    [oracle@node1 ~]$ srvctl stop asm -n node1
    [oracle@node1 ~]$ srvctl stop nodeapps –n node1

    启动 Oracle RAC 10g 环境

    第一步是启动节点应用程序(虚拟 IP、GSD、TNS 监听器和 ONS)。当成功启动节点应用程序后,启动 ASM 实例。最后,启动 Oracle 实例(和相关服务)以及企业管理器数据库控制台。

    [oracle@node1 ~]$ export ORACLE_SID=NOVADB
    [oracle@node1 ~]$ srvctl start nodeapps -n node1
    [oracle@node1 ~]$ srvctl start asm -n node1
    [oracle@node1 ~]$ srvctl start instance -d NOVADB -i NOVADB1
    [oracle@node1 ~]$ emctl start dbconsole

    使用 SRVCTL 启动/停止所有实例

    启动/停止所有实例及其启用的服务。我只是觉得有意思就把此步骤作为关闭所有实例的一种方法加进来了!

    [oracle@node1 ~]$ srvctl start database -d NOVADB
    [oracle@node1 ~]$ srvctl stop database -d NOVADB

    启停止监听
    [oracle@node1 ~]$lsnrctl start listener_hostb
    [oracle@node1 ~]$lsnrctl stop listener_hostb

    以下没经过测试呢,等待测试,工作太忙了..

    查看备份
    $ocrconfig -showbackup

    备份
    /data/oracle/crs/bin/ocrconfig -export /data/backup/rac/ocrdisk.bak

    还原 需要停掉所有的节点,Stop the Oracle Clusterware software on all of the nodes
    /data/oracle/crs/bin/ocrconfig -import file_name

    自动备份的还原
    # /data/oracle/crs/bin/ocrconfig -showbackup
    # /data/oracle/crs/bin/ocrconfig -restore /data/oracle/crs/cdata/db168crs/backup00.ocrhosta$cluvfy comp ocr -n all //检验

    ocr 检查
    #ocrcheck配置路径在
    /var/opt/oracle/ocrconfig_loc文件里面 如果需要更改OCR磁盘的路径配置。

    OCR磁盘空间检查
    # /data/oracle/crs/bin/ocrcheck
