RAC环境维护常用命令

郑重声明：由于本人水平有限，如有不对的地方请大神指正不甚感激（[email protected]）
由于最近种种原因没有更新博客，本打算更新索引使用方法，但由于最近对RAC操作比较多，记录了一些常用的命令。索引后序增加

1.1.1.1   查看spfile位置

SQL> show parameter spfile;

 

NAME                    TYPE        VALUE

----------------------------------------------- ------------------------------

spfile                  string      +DATA0/racdb007/spfileracdb007.ora

1.1.1.2   修改spfile参数

SQL> show parameter session;

 

NAME                                 TYPE        VALUE

----------------------------------------------- ------------------------------

java_max_sessionspace_size           integer     0

java_soft_sessionspace_limit         integer     0

license_max_sessions                 integer     0

license_sessions_warning             integer     0

session_cached_cursors               integer     50

session_max_open_files               integer     10

sessions                             integer     247

shared_server_sessions               integer

SQL> alter system set sessions=250 scope=spfile;

 

System altered.

注意：有些可以马上生效的参数不用加scope参数即可使用，如果加了scope命令那么就必须重启数据库才能生效

1.1.1.3    设置SPFILE路径

[oracle@rac4 dbs]$ pwd

/u01/app/oracle/product/11.2.0.3/db_1/dbs

[oracle@rac4 dbs]$ catinitemp2.ora

SPFILE='+DATA0/emp/spfileemp.ora'

1.1.2RAC环境

1.1.2.1    查看ORACLE守护进程

[oracle@rac3 ~]$ ls/etc/init.d/init.*

/etc/init.d/init.ohasd

10G为

1.1.2.2   查看节点信息

[grid@rac3~]$ olsnodes --help

Usage: olsnodes [ [-n] [-i] [-s] [-t][ | -l [-p]] | [-c] ] [-g] [-v]

       where

               -n print node number with the node name显示节点名

               -p print private interconnect address for the local node显示priIP

               -i print virtual IP address with the node name显示VIP

                print information for the specified node

               -l print information for the local node 显示自己节点信息

               -s print node status - active or inactive 显示节点状态

               -t print node type - pinned or unpinned 显示节点类型（固定、不固定）

               -g turn on logging 打开日志记录

               -v Run in debug mode; use at direction of Oracle Support only.开启debug模式

               -c print clusterware name输出集群名字

[grid@rac3~]$ olsnodes -i -n -s -t -g

rac3   1       rac3-vip        Active Unpinned

rac4   2       rac4-vip        Active Unpinned

1.1.2.3   查看集群网络状态

[grid@rac3~]$ oifcfg

 

Name:

       oifcfg - Oracle Interface Configuration Tool.

 

Usage: oifcfg iflist [-p [-n]]

       oifcfg setif {-node | -global}{/:}..设置网卡

       oifcfg getif [-node | -global] [ -if[/] [-type ] ]输出网卡信息

       oifcfg delif {{-node | -global}[[/]] [-force] | -force}

       oifcfg [-help]

 

        - name of the host, as known to a communicationsnetwork

         - name by whichthe interface is configured in the system

          - subnet addressof the interface

         - type of theinterface { cluster_interconnect | public }

[grid@rac3~]$ oifcfg getif

eth0 10.22.19.0  global  public

eth1 172.16.6.0  global  cluster_interconnect

1.1.2.4   查看CRS状态
