ORA-32017 ORA-16187异常处理

数据库：oracle 11.2.0.4

系统：CentOS 7.9

环境：rac(2节点)+dg

问题描述：往log_archive_config添加第二个备库orclhr时报ORA-32017、ORA-16187，如下所示：

SQL> alter system set log_archive_config='dg_config=((orcl,orcl_149,orclhr)';
alter system set log_archive_config='dg_config=((orcl,orcl_149,orclhr)'
*
ERROR at line 1:
ORA-32017: failure in updating SPFILE
ORA-16187: LOG_ARCHIVE_CONFIG contains duplicate, conflicting or invalid attributes

SQL> show parameter spfile

SQL> alter system set log_archive_config='dg_config=(orcl,orcl_149,orclhr)';

System altered.

处理方案：此处第一个备库orcl_149并没有开启实时应用，当将orcl_149备库启动实时应用后，添加恢复正常.

SQL> alter system set log_archive_config='dg_config=(orcl,orcl_149,orclsr)';

System altered.
SQL> alter system set log_archive_dest_3='service=orclsr lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=orclsr' sid='*';

System altered.
