在啟動數(shù)據(jù)庫的時候，報ORA-000205錯誤,詳細(xì)錯誤信息如下：

經(jīng)過檢查alert.log,，發(fā)現(xiàn)如下內(nèi)容：

確認(rèn)是因?yàn)锳SM實(shí)例錯誤導(dǎo)致數(shù)據(jù)庫實(shí)例無法啟動，下面著手解決ASM實(shí)例問題：
啟動ASM實(shí)例：
ora_test@oracle[/oracle/app/10.1/dbs]> export ORACLE_SID=+ASM
ora_test@oracle[/oracle/app/10.1/dbs]> sqlplus / as sysdba
SQL*Plus: Release 10.2.0.1.0 - Production on Fri Feb 12 19:14:12 2010

idle> startup
ASM instance started
Total System Global Area 79691776 bytes
Fixed Size 1217812 bytes
Variable Size 53308140 bytes
ASM Cache 25165824 bytes
ORA-15110: no diskgroups mounted |
經(jīng)過檢查，發(fā)現(xiàn)ASM的參數(shù)中沒有了asm_diskgroups參數(shù),，增加
修改后的asm的參數(shù)文件為：
ora_test@oracle[/oracle/app/10.1/dbs]> cat $ORACLE_HOME/dbs/init+ASM.ora
instance_type=asm
instance_name=+ASM
asm_diskgroups=DATA |
然后再重啟asm實(shí)例,，能夠正常啟動
ora_test@oracle[/oracle/app/10.1/dbs]> sqlplus / as sysdba
SQL*Plus: Release 10.2.0.1.0 - Production on Fri Feb 12 19:16:38 2010

用pfile生成spfile

在asm實(shí)例正常啟動之后,，數(shù)據(jù)庫實(shí)例也能夠正常啟動了
ora_test@oracle[/oracle/app/10.1/dbs]> export ORACLE_SID=cnhtm
