去查看后台alert日志，信息显示如下：
Errors in file /oracle/app/oracle/diag/rdbms/pdunq/powerdes/trace/powerdes_ora_26567.trc: ORA-19809: limit exceeded for recovery files ORA-19804: cannot reclaim 512 bytes disk space from 16106127360 limit ARCH: Error 19809 Creating archive log file to ‘/oracle/app/oracle/flash_recovery_area/PDUNQ/archivelog/2015_04_19/o1_mf_1_1_%u_.arc‘ Errors in file /oracle/app/oracle/diag/rdbms/pdunq/powerdes/trace/powerdes_ora_26567.trc: ORA-16038: log 1 sequence# 1 cannot be archived ORA-12170: TNS:Connect timeout occurred ORA-00312: online log 1 thread 1: ‘/home/oradata/powerdes/redo01.log‘ Errors in file /oracle/app/oracle/diag/rdbms/pdunq/powerdes/trace/powerdes_arc3_27693.trc: ORA-19815: WARNING: db_recovery_file_dest_size of 16106127360 bytes is 100.00% used, and has 0 remaining bytes available. ************************************************************************ USER (ospid: 26567): terminating the instance due to error 16038 You have following choices to free up space from recovery area: 1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard, then consider changing RMAN ARCHIVELOG DELETION POLICY. 2. Back up files to tertiary device such as tape using RMAN BACKUP RECOVERY AREA command. 3. Add disk space and increase db_recovery_file_dest_size parameter to reflect the new space. 4. Delete unnecessary files using RMAN DELETE command. If an operating system command was used to delete files, then use RMAN CROSSCHECK and DELETE EXPIRED commands. ************************************************************************ Instance terminated by USER, pid = 26567
【解决办法】： 1，可以通过修改过db_recovery_file_dest_size，把其值改大些。 alter system set db_recovery_file_dest_size=20G scope=spfile;
