oracle RAC——歸檔日志的開啟方法
==================================
g R 要修改cluster_database參數 G R和以後的版本就不需要了
例子(g R或之前)srvctl stop database d RAC節點 sql>startup mount SQL> alter system set log_archive_dest_=location=/racdb_arch scope=spfile sid=RACSQL> alter system set log_archive_dest_=location=/racdb_arch scope=spfile sid=RACSQL> alter system set log_archive_dest_=service=rac scope=spfile sid=RACSQL> alter system set log_archive_dest_=service=rac scope=spfile sid=RACSQL> alter system set standby_archive_dest=/racdb_arch scope=spfile sid=RACSQL> alter system set standby_archive_dest=/racdb_arch scope=spfile sid=RACsql>alter system set cluster_database=false scope=spfilesql>shutdown immediate sql>startup mount sql>alter database archivelog sql>alter database open sql>alter system set cluster_database=true scope=spfilesql>shutdown immediate srvctl start database d RAC
例子(g R或之後)節點 SQL>startup mountSQL> alter system set log_archive_dest_=location=/racdb_arch scope=spfile sid=RACSQL> alter system set log_archive_dest_=location=/racdb_arch scope=spfile sid=RACSQL> alter system set log_archive_dest_=service=rac scope=spfile sid=RACSQL> alter system set log_archive_dest_=service=rac scope=spfile sid=RACSQL> alter system set standby_archive_dest=/racdb_arch scope=spfile sid=RACSQL> alter system set standby_archive_dest=/racdb_arch scope=spfile sid=RACsrvctl stop database d RAC節點 SQL> startup mount SQL> alter database archivelogsrvctl start database d RAC
測試歸檔日志的切換
節點一二上分別執行切換日志操作如下SQL> alter system switch logfile 操作執行這條語句次
節點一查詢SQL> !ls l /racdb* /racdb_archtotal rwr—— oracle oinstall Oct __dbf rwr—— oracle oinstall Oct __dbf rwr—— oracle oinstall Oct __dbf rwr—— oracle oinstall Oct __dbf rwr—— oracle oinstall Oct __dbf /racdb_archtotal rwrw—— oracle oinstall Oct __dbf rwrw—— oracle oinstall Oct __dbf rwrw—— oracle oinstall Oct __dbf rwrw—— oracle oinstall Oct __dbf rwrw—— oracle oinstall Oct __dbf
節點二查詢
SQL> !ls l /racdb* /racdb_archtotal rwrw—— oracle oinstall Oct __dbf rwrw—— oracle oinstall Oct __dbf rwrw—— oracle oinstall Oct __dbf rwrw—— oracle oinstall Oct __dbf rwrw—— oracle oinstall Oct __dbf /racdb_archtotal rwr—— oracle oinstall Oct __dbf rwr—— oracle oinstall Oct __dbf rwr—— oracle oinstall Oct __dbf rwr—— oracle oinstall Oct __dbf rwr—— oracle oinstall Oct __dbf
