Question

如何获得rac环境中的主节点

Answer 1

1.通过执行ocrconfig -showbackup获得

在节点1上执行
[oracle@dbrac1 ~]$ ocrconfig -showbackup

dbrac1 2012/01/04 10:00:03 /opt/oracle/product/crs/cdata/crs

dbrac1 2012/01/04 06:00:03 /opt/oracle/product/crs/cdata/crs

dbrac1 2012/01/04 02:00:03 /opt/oracle/product/crs/cdata/crs

dbrac1 2012/01/02 10:00:02 /opt/oracle/product/crs/cdata/crs

dbrac1 2011/12/25 01:59:53 /opt/oracle/product/crs/cdata/crs

在节点2上执行
[oracle@dbrac2 ~]$ ocrconfig -showbackup

dbrac1 2012/01/04 10:00:03 /opt/oracle/product/crs/cdata/crs

dbrac1 2012/01/04 06:00:03 /opt/oracle/product/crs/cdata/crs

dbrac1 2012/01/04 02:00:03 /opt/oracle/product/crs/cdata/crs

dbrac1 2012/01/02 10:00:02 /opt/oracle/product/crs/cdata/crs

dbrac1 2011/12/25 01:59:53 /opt/oracle/product/crs/cdata/crs

2. 还可以通过下面的语句获得
$cat $ORA_CRS_HOME/log/`hostname`/cssd/ocssd* |grep master
or
$ for x in `ls -tr $ORA_CRS_HOME/log/`hostname`/cssd/ocssd* `; do grep -i "master node" $x ; done | tail -1
