第六章:load数据
1.loading data using direct_load insert
sql> insert /*+append */ into emp nologging
sql> select * from emp_old;
2.parallel direct-load insert
sql> alter session enable parallel dml;
sql> insert /*+parallel(emp,2) */ into emp nologging
sql> select * from emp_old;
3.using sql*loader
sql> sqlldr scott/tiger \
sql> control = ulcase6.ctl \
sql> log = ulcase6.log direct=true
第七章:reorganizing data
1.using expoty
$exp scott/tiger tables(dept,emp) file=c:\emp.dmp log=exp.log compress=n direct=y
2.using import
$imp scott/tiger tables(dept,emp) file=emp.dmp log=imp.log ignore=y
3.transporting a tablespace
sql>alter tablespace sales_ts read only;
$exp sys/.. file=xay.dmp transport_tablespace=y tablespace=sales_ts
triggers=n constraints=n
$copy datafile
$imp sys/.. file=xay.dmp transport_tablespace=y datafiles=(/disk1/sles01.dbf,/disk2
/sles02.dbf)
sql> alter tablespace sales_ts read write;
4.checking transport set
sql> dbms_tts.transport_set_check(ts_list =>''sales_ts'' ..,incl_constraints=>true);
在表transport_set_violations 中查看
sql> dbms_tts.isselfcontained 为true 是, 表示自包含
