今天測試部門的人叫我過去，說是數據庫當了，起不來了。 我過去看了看情況，做了如下操作 SQL> shutdown immediate數據庫已經關閉。已經卸載數據庫。ORACLE 例程已經關閉。SQL> startupORACLE 例程已經啟動。 Total System Global Area 135338868 bytesFixed Size 453492 bytesVariable Size 109051904 bytesDatabase Buffers 25165824 bytesRedo Buffers 667648 bytes數據庫裝載完畢。ORA-01092: ORACLE 例程終止。強行斷開連接 表面上看不出問題，我查看alert_oracas.log文件 SYS auditing is disabledStarting up ORACLE RDBMS Version: 9.2.0.1.0.System parameters with non-default values: processes = 150 timed_statistics = TRUE shared_pool_size = 50331648 large_pool_size = 8388608 java_pool_size = 33554432 control_files = f:\oracle\oradata\oracas\CONTROL01.CTL, f:\oracle\oradata\oracas\CONTROL02.CTL, f:\oracle\oradata\oracas\CONTROL03.CTL db_block_size = 8192 db_cache_size = 25165824 compatible = 9.2.0.0.0 db_file_multiblock_read_count= 16 fast_start_mttr_target = 300 undo_management = AUTO undo_tablespace = UNDOSTB1 undo_retention = 10800 remote_login_passwordfile= EXCLUSIVE db_domain = instance_name = oracas dispatchers = (PROTOCOL=TCP) (SERVICE=oracasXDB) job_queue_processes = 10 hash_join_enabled = TRUE background_dump_dest = f:\oracle\admin\oracas\bdump user_dump_dest = f:\oracle\admin\oracas\udump core_dump_dest = f:\oracle\admin\oracas\cdump sort_area_size = 524288 db_name = oracas open_cursors = 300 star_transformation_enabled= FALSE query_rewrite_enabled = FALSE pga_aggregate_target = 19922944 aq_tm_processes = 1PMON started with pid=2DBW0 started with pid=3LGWR started with pid=4CKPT started with pid=5SMON started with pid=6RECO started with pid=7CJQ0 started with pid=8QMN0 started with pid=9Mon Apr 18 17:30:25 2005starting up 1 shared server(s) ...starting up 1 dispatcher(s) for network address '(ADDRESS=(PARTIAL=YES)(PROTOCOL=TCP))'...Mon Apr 18 17:30:26 2005ALTER DATABASE MOUNTMon Apr 18 17:30:30 2005Successful mount of redo thread 1, with mount id 2424210674.Mon Apr 18 17:30:30 2005Database mounted in Exclusive Mode.Completed: ALTER DATABASE MOUNTMon Apr 18 17:30:30 2005ALTER DATABASE OPENMon Apr 18 17:30:32 2005Thread 1 opened at log sequence 105 Current log# 2 seq# 105 mem# 0: F:\ORACLE\ORADATA\ORACAS\REDO02.LOGSuccessful open of redo thread 1.Mon Apr 18 17:30:32 2005SMON: enabling cache recoveryMon Apr 18 17:30:34 2005Errors in file f:\oracle\admin\oracas\udump\oracas_ora_3404.trc:ORA-30012: 撤消表空間 'UNDOSTB1' 不存在或類型不正確 Mon Apr 18 17:30:34 2005Error 30012 happened during db open, shutting down databaseUSER: terminating instance due to error 30012Mon Apr 18 17:30:35 2005Errors in file f:\oracle\admin\oracas\bdump\oracas_smon_996.trc:ORA-30012: undo tablespace '' does not exist or of wrong type Mon Apr 18 17:30:35 2005Errors in file f:\oracle\admin\oracas\bdump\oracas_pmon_3500.trc:ORA-30012: undo tablespace '' does not exist or of wrong type Instance terminated by USER, pid = 3404ORA-1092 signalled during: ALTER DATABASE OPEN... 於是我查看了以下信息來確認undo表空間的問題 SQL> conn sys/sys@oracas as sysdba已連接到空閒例程。SQL> startup mountORACLE 例程已經啟動。 Total System Global Area 135338868 bytesFixed Size 453492 bytesVariable Size 109051904 bytesDatabase Buffers 25165824 bytesRedo Buffers 667648 bytes數據庫裝載完畢。SQL> select name from v$datafile;

文件已創建。 修改pfile文件 #*.undo_management='AUTO'#*.undo_tablespace='UNDOSTB1'undo_management=manualundo_tablespace='system' 關閉數據庫，並且從目錄F:\oracle\ora92\database下去掉SPFILEORACAS.ORA文件 重新啟動 SQL> shutdown immediateORA-01109: 數據庫未打開 已經卸載數據庫。ORACLE 例程已經關閉。SQL> startup mountORACLE 例程已經啟動。 Total System Global Area 135338868 bytesFixed Size 453492 bytesVariable Size 109051904 bytesDatabase Buffers 25165824 bytesRedo Buffers 667648 bytes數據庫裝載完畢。SQL> alter database open;

NAME------------------------------CWMLITEDRSYSEXAMPLEINDXODMSYSTEMTOOLSUNDOTBS1USERSXDBTEMPTSCAS1TSCAS2TSCAS3TSCAS4TSCASINDX1TSCASINDX2SNAPSHOT_TS 並且打開圖形界面查看，這時候才發現undo表空間的名字是UNDOTBS1 其實早就能發現的，大家以後分析問題一定不要太快下結論，要自己分析。。。 於是做以下操作改變undo 表空間的名字 SQL> create spfile from pfile; 文件已創建。 SQL> shutdown immediate數據庫已經關閉。已經卸載數據庫。ORACLE 例程已經關閉。SQL> startupORACLE 例程已經啟動。 Total System Global Area 135338868 bytesFixed Size 453492 bytesVariable Size 109051904 bytesDatabase Buffers 25165824 bytesRedo Buffers 667648 bytes數據庫裝載完畢。數據庫已經打開。SQL> show parameter undo NAME TYPE VALUE------------------------------------ ----------- ------------------------------undo_management string MANUALundo_retention integer 10800undo_suppress_errors boolean FALSEundo_tablespace string systemSQL> alter database set undo_management=auto;alter database set undo_management=auto *ERROR 位於第 1 行:ORA-02231: 缺少或無效的 ALTER DATABASE 選項 SQL> alter database set undo_management=auto scope=spfile;alter database set undo_management=auto scope=spfile *ERROR 位於第 1 行:ORA-02231: 缺少或無效的 ALTER DATABASE 選項 SQL> alter system set undo_management=auto scope=spfile;
