在安装CRS时系统会要求输入cluster name, 缺省值是crs。安装后如果想查cluster name,可以从OCR中得到。
执行ocrdump命令，然后从OCRDUMPFILE中找出clustername.
......
[SYSTEM.css.clustername]
ORATEXT : crs
SECURITY : {USER_PERMISSION : PROCR_ALL_ACCESS, GROUP_PERMISSION : PROCR_READ, OTHER_PERMISSION : PROCR_READ, USER_NAME : root, GROU
P_NAME : root}
......
ORATEXT对应的项应该就是cluster name了。

另外，还可以从ocr缺省的自动备份路径来找。Oracle RAC: Frequently Asked Questions这篇文档里有这样一段话

With Oracle Clusterware 10g, how do you backup the OCR?

There is an automatic backup mechanism for OCR.  The default location is : $ORA_CRS_HOME\cdata\"clustername"\

To display backups : ocrconfig -showbackup
To restore a backup :  ocrconfig -restore 

这说明OCR缺省的备份路径里就含有clustername,如果没改过OCR备份路径，也可以从这里得到
clustername.

ofs00biiacc002>ocrconfig -showbackup


ofs00biidrc001     2008/12/10 10:22:16     /app/oracle/product/crs/cdata/crs

ofs00biidrc001     2008/12/10 06:22:15     /app/oracle/product/crs/cdata/crs

ofs00biidrc001     2008/12/10 04:50:47     /app/oracle/product/crs/cdata/crs

ofs00biidrc001     2008/12/08 12:50:36     /app/oracle/product/crs/cdata/crs

ofs00biidrc001     2008/12/04 03:25:48     /app/oracle/product/crs/cdata/crs

这里的crs就是cluster name.

另外有一个命令也可以得到cluster name. (cemutlo -n)
ofs00biiacc002>./cemutlo
Usage: ./cemutlo.bin [-n] [-w]
        where:
        -n prints the cluster name
        -w prints the clusterware version in the following format:
                 ::


ofs00biiacc002>./cemutlo -n
crs
