RAC维护工具集

• 1.节点层
• 2.网络层
• 3.集群层
• 4.应用层

本文实验环境：
10.2.0.5 Clusterware + RAC
11.2.0.4 GI + RAC
通过对比命令的输出，也可大致了解10g RAC 到 11g RAC 发生的变化。

1.节点层

1) olsnodes
olsnodes: 列出集群中所有的节点。

10g(10.2.0.5):

[oracle@oradb28 ~]$ olsnodes -h
Usage: olsnodes [-n] [-p] [-i] [ | -l] [-g] [-v]
        where
                -n print node number with the node name
                -p print private interconnect name with the node name
                -i print virtual IP name with the node name
                 print information for the specified node
                -l print information for the local node 
                -g turn on logging 
                -v run in verbose mode 

11g(11.2.0.4):

[grid@oradb23 ~]$ olsnodes -h
Usage: olsnodes [ [-n] [-i] [-s] [-t] [ | -l [-p]] | [-c] ] [-g] [-v]
        where
                -n print node number with the node name
                -p print private interconnect address for the local node
                -i print virtual IP address with the node name
                 print information for the specified node
                -l print information for the local node 
                -s print node status - active or inactive 
                -t print node type - pinned or unpinned 
                -g turn on logging 
                -v Run in debug mode; use at direction of Oracle Support only.
                -c print clusterware name

2.网络层

公有网络和私有网络。
1) oifcfg
oifcfg: Oracle Interface配置工具。

10g(10.2.0.5):

[oracle@oradb28 ~]$ oifcfg

Name:
        oifcfg - Oracle Interface Configuration Tool.

Usage:  oifcfg iflist [-p [-n]]
        oifcfg setif {-node  | -global} {/:}...
        oifcfg getif [-node  | -global] [ -if [/] [-type ] ]
        oifcfg delif [-node  | -global] [[/]]
        oifcfg [-help]

         - name of the host, as known to a communications network
          - name by which the interface is configured in the system
           - subnet address of the interface
          - type of the interface { cluster_interconnect | public | storage }

11g(11.2.0.4):

[grid@oradb23 ~]$ oifcfg

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

         - name of the host, as known to a communications network
          - name by which the interface is configured in the system
           - subnet address of the interface
          - type of the interface { cluster_interconnect | public }

2) x$ksxpia
集群的网络信息。
SQL> select * from x$ksxpia;

10g(10.2.0.5):

SQL> select * from x$ksxpia;

ADDR                   INDX    INST_ID PUB_KSXPIA PICKED_KSXPIA                       NAME_KSXPIA     IP_KSXPIA

11g(11.2.0.4):

SQL> select * from x$ksxpia;

ADDR                   INDX    INST_ID PUB_KSXPIA PICKED_KSXPIA                       NAME_KSXPIA     IP_KSXPIA

00007F2490C58CE0          1          1 Y          GPnP                                eth0            192.168.1.23
00007F2490C58CE0          2          1 Y          GPnP                                eth0:1          192.168.1.53

发现11.2.0.4版本，内网地址是169.254.xx.xx,是HAIP特性。
另外11.2.0.4版本，会把自己节点的vip和scan vip也查询出来。

3.集群层

crsctl;
ocrcheck, ocrdump, ocrconfig;
crs_profile, crs_register, crs_start, crs_stat, crs_relocate, crs_stop, crs_unregister;

1) crsctl

 If necesary any of these commands can be run with additional tracing by
 adding a "trace" argument at the very front.
 Example: crsctl trace check css
