[root@his1 ~]# cd /app/grid/product/11.2.0/grid/cdata/his1.olr
看到olr文件损坏
用以下命令，可以重建OLR文件:

[root@his1 ~]#ocrcheck -config -local
Oracle Local Registry configuration is :
Device/File Name : /app/grid/product/11.2.0/grid/cdata/his1.olr

[root@his1 ~]#touch /app/grid/product/11.2.0/grid/cdata/his1.olr 创建olr文件

[root@his1 ~]#/app/11.2.0/grid/bin/ocrconfig -local -restore /app/grid/product/11.2.0/grid/cdata/backup_20120810_102624.olr

用手动备份文件还原

[root@his1 ~]# cat /etc/oracle/olr.loc
olrconfig_loc=/app/grid/product/11.2.0/grid/cdata/his1.olr
crs_home=/app/grid

OLR: Oracle Local Registry

OCR manages Oracle Clusterware and Oracle RAC database configuration information
OLR resides on every node in the cluster and manages Oracle Clusterware
configuration information for each particular node

Voting disks manage information about node membership. Each voting disk must be
accessible by all nodes in the cluster for nodes to be members of the cluster

OLR is a registry similar to OCR located on each node in a cluster,
but contains information specific to each node.
It contains manageability information about Oracle Clusterware,
including dependencies between various services.
Oracle High Availability Services uses this information.
OLR is located on local storage on each node in a cluster.
Its default location is in the path Grid_home/cdata/host_name.olr,
where Grid_home is the Oracle Grid Infrastructure home,
and host_name is the host name of the node.
