Oracle 11G R2  RAC修改归档模式


库建好以后默认是非归档模式,需要修改一下


测试第一种方法:

总结一下顺序:


第一种:


$                       srvctl stop database -d momorac
sqlplus任一节点  startup mount
                         alter database archivelog 或者   alter database noarchivelog;
                         shutdown immediate
$                       srvctl start database -d momorac

第二种:

sqlplus任一节点  alter system set cluster_database=false scope=spfile sid='*';
$                       srvctl stop database -d momorac
sqlplus任一节点  startup mount
                         alter database archivelog 或者   alter database noarchivelog;
                         alter system set cluster_database=true scope=spfile sid='*';
                         shutdown immediate
$                       srvctl start database -d momorac
