第一章：日志管理
1.forcing log switches
sql> alter system switch logfile;
2.forcing checkpoints
sql> alter system checkpoint;
3.adding online redo log groups
sql> alter database add logfile [group 4]
sql> (''/disk3/log4a.rdo'',''/disk4/log4b.rdo'') size 1m;
4.adding online redo log members
sql> alter database add logfile member
sql> ''/disk3/log1b.rdo'' to group 1,
sql> ''/disk4/log2b.rdo'' to group 2;
5.changes the name of the online redo logfile
sql> alter database rename file ''c:/Oracle/oradata/oradb/redo01.log''
sql> to ''c:/Oracle/oradata/redo01.log'';
6.drop online redo log groups
sql> alter database drop logfile group 3;
7.drop online redo log members
sql> alter database drop logfile member ''c:/Oracle/oradata/redo01.log'';
8.clearing online redo log files
sql> alter database clear [unarchived] logfile ''c:/Oracle/log2a.rdo'';
9.using logminer analyzing redo logfiles
a. in the init.ora specify utl_file_dir = '' ''
b. sql> execute dbms_logmnr_d.build(''oradb.ora'',''c:Oracleoradblog'');
c. sql> execute dbms_logmnr_add_logfile(''c:Oracleoradataoradbredo01.log'',
sql> dbms_logmnr.new);
d. sql> execute dbms_logmnr.add_logfile(''c:Oracleoradataoradbredo02.log'',
sql> dbms_logmnr.addfile);
e. sql> execute dbms_logmnr.start_logmnr(dictfilename=>''c:Oracleoradblogoradb.ora'');
f. sql> select * from v$logmnr_contents(v$logmnr_dictionary,v$logmnr_parameters
sql> v$logmnr_logs);
g. sql> execute dbms_logmnr.end_logmnr;
第二章：表空間管理
1.create tablespaces
sql> create tablespace tablespace_name datafile ''c:Oracleoradatafile1.dbf'' size 100m,
sql> ''c:Oracleoradatafile2.dbf'' size 100m minimum extent 550k [logging/nologging]
sql> default storage (initial 500k next 500k maxextents 500 pctinccease 0)
