ORA-03113: end-of-file on communication channel 解决方法今天在测试数据库中对一个表插入了大量的数据, 导致数据库卡死 hang 住, 重启数据库后报错如下:1. 以管理员身份运行C:Documents and Settingsdaviddsqlplus / as sysdbaSQL*Plus: Release 11.2.0.1.0 Production on Fri Dec 5 08:50:23 2014Copyright (c) 1982, 2010, Oracle.

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.*原来是大批量的数据插入导致闪回空间不足, 最常用的办法删除不需要的归档日志文件或者增加闪回空间大小(db_recovery_file_dest_size)查看闪回空间大小(db_recovery_file_dest_size)5. 查看闪回空间大小SQL show parameter db_recovery_file_dest_size;NAME TYPE VALUE- - -db_recovery_file_dest_size big integer 4977M6. 查看 rman 设定RMAN show all;RMAN configuration parameters for database with db_unique_name DAVID are:CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 14 DAYS;CONFIGURE BACKUP OPTIMIZATION OFF; # defaultCONFIGURE DEFAULT DEVICE TYPE TO DISK; # defaultCONFIGURE CONTROLFILE AUTOBACKUP ON;CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO g:oraclebackup%F;CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # defaultCONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # defaultCONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # defaultCONFIGURE MAXSETSIZE TO UNLIMITED; # defaultCONFIGURE ENCRYPTION FOR DATABASE OFF; # defaultCONFIGURE ENCRYPTION ALGORITHM AES128; # defaultCONFIGURE COMPRESSION ALGORITHM BASIC AS OF RELEASE DEFAULT OPTIMIZE FOR LOAD TRUE ; # defaultCONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # defaultCONFIGURE SNAPSHOT CONTROLFILE NAME TO G:APPDAVIDDPRODUCT11.2.0DBHOME_1DATABASESNCFDAVID.ORA; # default7. 将备份策略改为基于冗余数量的备份策略RMAN configure retention policy to redundancy 5;old RMAN configuration parameters:CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 14 DAYS;new RMAN configuration parameters:CONFIGURE RETENTION POLICY TO REDUNDANCY 5;new RMAN configuration parameters are successfully stored8. 全部显示RMAN show all;RMAN configuration parameters for database with db_unique_name DAVID are:CONFIGURE RETENTION POLICY TO REDUNDANCY 5;CONFIGURE BACKUP OPTIMIZATION OFF; # defaultCONFIGURE DEFAULT DEVICE TYPE TO DISK; # defaultCONFIGURE CONTROLFILE AUTOBACKUP ON;CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO g:oraclebackup%F;CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # defaultCONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # defaultCONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # defaultCONFIGURE MAXSETSIZE TO UNLIMITED; # defaultCONFIGURE ENCRYPTION FOR DATABASE OFF; # defaultCONFIGURE ENCRYPTION ALGORITHM AES128; # defaultCONFIGURE COMPRESSION ALGORITHM BASIC AS OF RELEASE DEFAULT OPTIMIZE FOR LOAD TRUE ; # defaultCONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # defaultCONFIGURE SNAPSHOT CONTROLFILE NAME TO G:APPDAVIDDPRODUCT11.2.0DBHOME_1DATABASESNCFDAVID.ORA; # default9. 手动删除不需要的归档日志文件 (删除 3 天以前的日志记录)rman delete archivelog all completed before sysdate - 310. 另外一种方法, 增加 db_recovery_file_dest_size 大小SQL alter system
