我们在诊断Oracle backup restore问题时总是希望能获得足够的诊断信息，一般来说RDA会是一个最好的诊断信息收集工具，但是有时候客户会很反感使用RDA(不信任感)，这里我们提供一段专门用来收集oracle备份恢复信息的脚本。 运行以下脚本需要设置合理的"ORACLE_HOME、ORACLE_SID"环境变量，并设置NLS_DATE_FORMAT环境变量，如 
NLS_DATE_FORMAT="DD-MON-RRRR HH24:MI:SS"
export NLS_DATE_FORMAT
以"rman target /"登陆并运行: 
spool log to rman_report.log
set echo on
show all;
report schema;
list incarnation;
list backup summary;
list backup;
list copy;
report need backup;
report obsolete;
restore database preview;
spool log off
以下脚本在sqlplus中以sysdba身份执行，执行要求数据库至少处于mounted已加载状态下；注意该原始脚本是只读readonly的，它仅仅是读取数据字典，不会造成危害，当然请确保你的脚本来源!!
