Oracle9i新特點(diǎn)：SPFILE的使用--How to set events with spfile and etc. Last Updated: Wednesday, 2004-10-27 0:39 Eygle ; 本文發(fā)表于itpub技術(shù)叢書《Oracle數(shù)據(jù)庫DBA專題技術(shù)精粹》,未經(jīng)許可,嚴(yán)禁轉(zhuǎn)載本文. 原文出處:http://www.eygle.com/faq/Oracle9i.New.Feature.Spfile.05.htm七. 設(shè)置Events事件Events事件是Oracle的重要診斷工具及問題解決辦法，很多時候需要通過Events設(shè)置來屏蔽或者更改Oracle的行為，下面我們來看一下怎樣修改spfile，增加Events事件設(shè)置：SQL> alter system set event='10841 trace name context forever' scope=spfile;System altered.SQL> startup force;ORACLE instance started.Total System Global Area 101782380 bytesFixed Size 451436 bytesVariable Size 75497472 bytesDatabase Buffers 25165824 bytesRedo Buffers 667648 bytesDatabase mounted.Database opened.SQL> show parameter eventNAME TYPE VALUE------------------------------------ ----------- ------------------------------event string 10841 trace name context forever 順便提一句，10841事件是用于解決Oracle9i中JDBC Thin Driver問題的一個方法，假如你的alert.log文件中出現(xiàn)以下錯誤提示: Wed Jan 7 17:17:08 2004Errors in file /opt/oracle/admin/phsdb/udump/phsdb_ora_1775.trc:ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []Wed Jan 7 17:17:18 2004Errors in file /opt/oracle/admin/phsdb/udump/phsdb_ora_1777.trc:ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []Wed Jan 7 17:17:24 2004Errors in file /opt/oracle/admin/phsdb/udump/phsdb_ora_1783.trc:ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []Wed Jan 7 17:17:31 2004Errors in file /opt/oracle/admin/phsdb/udump/phsdb_ora_1785.trc:ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []Wed Jan 7 17:17:39 2004Errors in file /opt/oracle/admin/phsdb/udump/phsdb_ora_1777.trc:ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []Wed Jan 7 17:17:45 2004Errors in file /opt/oracle/admin/phsdb/udump/phsdb_ora_1783.trc:ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []Wed Jan 7 17:17:52 2004Errors in file /opt/oracle/admin/phsdb/udump/phsdb_ora_1787.trc:ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []Wed Jan 7 17:18:11 2004Errors in file /opt/oracle/admin/phsdb/udump/phsdb_ora_1791.trc:ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []Wed Jan 7 17:18:19 2004Errors in file /opt/oracle/admin/phsdb/udump/phsdb_ora_1785.trc:ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], [] 那么，很不幸，你很可能是碰到了bug: 1725012通過設(shè)置以上事件，可以屏蔽和解決這個ORA-00600錯誤.具體你可以參考Metalink相關(guān)文檔。 八. 導(dǎo)出SPFILE文件SPFILE文件可以導(dǎo)出為文本文件，使用導(dǎo)出、創(chuàng)建過程你可以向SPFILE中添加參數(shù)。SQL> create pfile='e:initeyglen.ora' from spfile;文件已創(chuàng)建。SQL> shutdown immediate數(shù)據(jù)庫已經(jīng)關(guān)閉。已經(jīng)卸載數(shù)據(jù)庫。ORACLE 例程已經(jīng)關(guān)閉。 Initeyglen.ora文件的內(nèi)容 *.aq_tm_processes=1*.background_dump_dest='e:oracleadmineyglenbdump'*.compatible='9.2.0.0.0'*.control_files='e:oracleoradataeyglencontrol01.ctl','e:oracleoradataeyglencontrol02.ctl','e:oracleoradataeyglencontrol03.ctl'*.core_dump_dest='e:oracleadmineyglencdump'*.db_block_size=8192*.db_cache_size=25165824*.db_domain=''*.db_file_multiblock_read_count=16*.db_name='eyglen'*.dispatchers='(PROTOCOL=TCP) (SERVICE=eyglenXDB)'*.fast_start_mttr_target=300*.hash_join_enabled=TRUE*.instance_name='eyglen'*.Java_pool_size=33554432*.job_queue_processes=10*.large_pool_size=8388608*.open_cursors=300*.pga_aggregate_target=25165824*.processes=150*.query_rewrite_enabled='FALSE'*.remote_login_passWordfile='EXCLUSIVE'*.shared_pool_size=50331648*.sort_area_size=524288*.sql_trace=FALSE*.star_transformation_enabled='FALSE'*.timed_statistics=TRUE*.undo_management='AUTO'*.undo_retention=10800*.undo_tablespace='UNDOTBS1' *.user_dump_dest='e:oracleadmineyglenudump'然后我們可以使用這個pfile，或者手動修改其中的參數(shù)以啟動數(shù)據(jù)庫。我們修改這個pfile，增加一行*.log_archive_start=true使用這個PFILE啟動數(shù)據(jù)庫SQL> startup pfile='e:initeyglen.ora'ORACLE 例程已經(jīng)啟動。Total System Global Area 135338868 bytesFixed Size 453492 bytesVariable Size 109051904 bytesDatabase Buffers 25165824 bytesRedo Buffers 667648 bytes數(shù)據(jù)庫裝載完畢。數(shù)據(jù)庫已經(jīng)打開。SQL> show parameter log_archive_startNAME TYPE------------------------------------ ----------------------VALUE------------------------------log_archive_start booleanTRUESQL> 然后我們可以使用新的PFILE創(chuàng)建SPFILESQL> create spfile from pfile='e:initeyglen.ora';
