1- stop nodeapps 

2- As root,  vi the script $ORA_CRS_HOME/bin/racgvip and change the value of  variable FAIL_WHEN_DEFAULTGW_NOT_FOUND=0 .  3- start nodeapps and you should see the resources ONLINE  

You can simply change the parameter one by one on each node...

1. alter system set cluster_database=false scope=spfile sid='<firstinstanceid>'; 2 Bounce the instance. srvctl start nodeapps -n db2 srvctl stop nodeapps -n db2

crs_stat

crs_start ora.db2.ASM2.asm

crs_start all

crsctl check crs

/u01/crs/oracle/product/10.2/crs/bin/srvctl start instance -d DB -i DB2

 

$srvctl setenv database -d DB -T TNS_ADMIN=$ORACLE_HOME/network/admin/

./srvctl setenv nodeapps -n db2 -t TNS_ADMIN=/u01/app/oracle/product/10.2.0/db_1/network/admin/

$ srvctl start database -d DB

以上方法试过无用，/etc/init.d/oracleasm listdisks 没有结果，/etc/init.d/oracleasm enable

 提示Initializing the Oracle ASMLib driver:                     [FAILED]

  rpm -q oracleasm-`uname -r` 提示包没有安装，检查内核版本，发现版本升级了，晕，难怪ASM不正常了，下载相应版本的ASM安装后

/etc/init.d/oracleasm enable 提示正常，/etc/init.d/oracleasm listdisks 显示正常.

srvctl start nodeapps -n db2 实例和ASM的服务不正常，强行启动。

./crs_start ora.db2.ASM2.asm -f

./crs_start ora.DB.DB2.inst -f

./crs_stat -t显示都正常

分别访问各个节点，查询数据，一切正常。
