Script:检查数据库当前是否有备份操作在执行中

以下脚本可以用于检测数据库当前是否有备份操作在执行中:

SELECT DECODE(os_backup.backup + rman_backup.backup, 0, 'FALSE', 'TRUE') backup
  FROM (SELECT COUNT(*) backup FROM gv$backup WHERE status = 'ACTIVE') os_backup,
       (SELECT COUNT(*) backup
          FROM gv$session
         WHERE status = 'ACTIVE'
           AND client_info like '%rman%') rman_backup
/
