java 导入导出的 命令

$exp lddba/ld_321@192.168.1.3/testora file=E:\db_bak\ld20170219_1testora.dmp log=E:\db_bak\ld20170219_1testora.log full=y;
$imp lddba/ld_321@127.0.0.1/ldora file=E:\ld20170225_1test.dmp log=E:\ld20170225_1testimp.log fromuser=lddba touser=lddba statistics=none;
/***********************************************************************

statistics=none是为了不导入统计信息，如果表很大，导入统计信息会花很长时间;

rows：表示导出数据行full( 全库导出): 导出除ORDSYS,MDSYS,CTXSYS,ORDPLUGINS,LBACSYS 这些系统用户之外的所有用户的数据.下面这个应该是imp时的参数，exp没有ignore=y 表示忽略创建错误，继续后面的操作

show parameter deferred_segment_creation

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
deferred_segment_creation boolean TRUE
SQL> alter system set deferred_segment_creation=false;

系统已更改。

SQL> show parameter deferred_segment_creation

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
deferred_segment_creation boolean FALSE

处理后需要重启 才能生效

select 'alter table '|| table_name|| ' allocate extent ; ' from user_tables where NUM_rows =0;
