显示 db_recovery_file_dest_size36个G已经满了

数据库启动不了，rman target/  不行
先用root到/pb/oracle_recovery/OWLMK/archivelog删除几个最老的目录。
然后
sqlplus "/as sysdba"
startup;
仍然启动不了。
startup mount;
能启动

另外打开一个窗口：
su - lmoracle
rman target /
crosscheck archivelog all;
delete expired archivelog all;
delete noprompt archivelog until time "sysdate -3";

在sqlplus中执行
shutdown;
退出重新进入 sqlplus "/as sysdba"
startup;
正常启动
