今天在用crs启动集群时,发现不能带起第二个节点的实例

[oracle@p520:/oracle/app/oracle]$crs_stat -t

ora.orcl.orcl2.inst.log 日志记录如下:

SQL*Plus: Release 10.2.0.4.0 - Production on Fri Jun 4 10:42:26 2010

Enter user-name: Connected to an idle instance.

SQL> ORA-01565: error in identifying file '+dgtest/orcl/spfileorcl.ora'
ORA-175'

处理过程如下:

手工启动这个节点的实例是可以启动的

[oracle@p650:/oracle/app/oracle/product/10.2.0/clusterdb/log/p650/racg]$export ORACLE_SID=orcl2
[oracle@p650:/oracle/app/oracle/product/10.2.0/clusterdb/log/p650/racg]$sqlplus "/as sysdba"

SQL*Plus: Release 10.2.0.4.0 - Production on Fri Jun 4 10:54:02 2010

Connected to an idle instance.

我们可以看到是DGTEST是大写的

SPFILE='+dgtest/orcl/spfileorcl.ora'

而initorcl2.ora 下面的spfile dgtest是小写的

更改成大写
[oracle@p650:/oracle/app/oracle/product/10.2.0/clusterdb/dbs]$vi initorcl2.ora
"initorcl2.ora" 1 line, 37 characters
SPFILE='+DGTEST/orcl/spfileorcl.ora'

srvctl 修改database spfile 参数

[oracle@p650:/oracle/app/oracle/product/10.2.0/clusterdb/dbs]$srvctl modify database -d orcl -o /oracle/app/oracle/product/10.2.0/clusterdb -p +DGTEST/orcl/spfileorcl.ora

后再启动crs,能带起节点2数据库

[oracle@p650:/oracle/app/oracle]$crs_stat -t

ora.p650.ons   application    ONLINE    ONLINE    p650

总结:数据库实例的spfile参数和$ORACLE_HOME/dbs/initsid.ora文件要一致,有大小写区分

要注意。
