Connect internal only, until freed 错误的处理方法 1. 用sys用户登录 sqlplus sys/pass@tt as sysdba 2. 看看archiv log所在位置 SQL> show parameter log_archive_dest; NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ log_archive_dest string log_archive_dest_1 string log_archive_dest_10 string 3. 一般VALUE为空时,可以用archive log list;检查一下归档目录和log sequence SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 360 Next log sequence to archive 360 Current log sequence 362 4. 检查flash recovery area的使用情况,可以看见archivelog已经很大了,达到96.62 SQL> select * from V$FLASH_RECOVERY_AREA_USAGE; FILE_TYPE PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES ------------ ------------------ ------------------------- --------------- CONTROLFILE .13 0 1 ONLINELOG 2.93 0 3 ARCHIVELOG 96.62 0 141 BACKUPPIECE 0 0 0 IMAGECOPY 0 0 0 FLASHBACKLOG 0 0 0 5. 计算flash recovery area已经占用的空间 SQL> select sum(percent_space_used)*3/100 from v$flash_recovery_area_usage; SUM(PERCENT_SPACE_USED)*3/100 ----------------------------- 2.9904 6. 找到recovery目录, show parameter recover SQL> show parameter recover; NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ db_recovery_file_dest string /u01/app/oracle/flash_recovery_area db_recovery_file_dest_size big integer 5G recovery_parallelism integer 0 7 上述结果告诉我们,归档位置用的是默认值,放在flash_recovery_area下(db_recovery_file_dest目录=/u01/app/oracle/flash_recovery_area) [root@sha3 10.2.0]# echo $ORACLE_BASE /u01/app/oracle [root@sha3 10.2.0]# cd $ORACLE_BASE/flash_recovery_area/tt/archivelog 转移或清除对应的归档日志, 删除一些不用的日期目录的文件,注意保留最后几个文件(比如360以后的) --------------------------------------------------------------------------------------- 注意: 在删除归档日志后,必须用RMAN维护控制文件,否则空间显示仍然不释放。 --------------------------------------------------------------------------------------- 8. rman target sys/pass [root@sha3 oracle]# rman target sys/pass Recovery Manager: Release 10.2.0.4.0 - Production on Tue Jan 20 01:41:26 2009 Copyright (c) 1982, 2007, Oracle.
