EXP 边导出边压缩打包

exp 可以导出oracle 的数据库逻辑备份,但一般都是导出完成后再用压缩工具打包,有没有边导出连压缩的办法呢?有

下面就用exp\gzip实现

shell版本bash

在rhel 5下操作

SQL> conn test/test;
Connected.
SQL> select * from tab;

TNAME                                                        TABTYPE
———————————————————— ————–
CLUSTERID
———-
TEST_TRAN                                                    TABLE

TEST_UNUSE                                                   TABLE

SQL> set linesize 200
SQL> run
1* select * from tab

TNAME                                                        TABTYPE         CLUSTERID
———————————————————— ————– ———-
TEST_TRAN                                                    TABLE
TEST_UNUSE                                                   TABLE

    The DC15 The Ball series currently contains four vacuum models the all floors, animal, total clean, and full kit. If a kitchen has room to accommodate a microwave oven, it should also be able to take one of these.
