oracle打开报错:


SQL> alter database open

  2  ;
alter database open
*
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Process ID: 29196
Session ID: 1144 Serial number: 7

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:

************************************************************************
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; 


SQL> startup mount
ORACLE instance started.


Total System Global Area 3373858816 bytes
Fixed Size    2218032 bytes
Variable Size 1862272976 bytes
Database Buffers 1493172224 bytes
Redo Buffers   16195584 bytes
Database mounted.
SQL> alter system set db_recovery_file_dest_size=20G scope=spfile; 


System altered.


SQL> 
SQL> alter database open
  2  ;


Database altered.


SQL> 


2,删除过期的归档日志,使用操作系统或RMAN DELETE 命令删除过期的命令。如果使用操作系统命令删除文件,要用rman执行
   crosscheck archivelog all;
   crosscheck archivelog all;
