如何制作数据库的物理副本？

Question

我正在寻找使用 Toad 制作 DB2 数据库副本的解决方案。

我试过这样的 db2move 命令：

db2move sample COPY -sn BASESAT -co target_db schema_map "((BASESAT,BASESAT4))" -u SATURNE

BASESAT 是我的数据库，BASESAT4 是我要创建的副本

我收到这个错误：

当我尝试命令模式时。我明白了

也许这对你有帮助。

创建示例数据库；

 user@host:/home/db2inst1:>db2 "create db sampledb"
DB20000I  The CREATE DATABASE command completed successfully.

user@host:/home/db2inst1:>db2 connect to sampledb

   Database Connection Information

 Database server        = DB2
 SQL authorization ID   = DB2INST1
 Local database alias   = SAMPLEDB

样本table；

user@host:/home/db2inst1:>db2 "CREATE TABLE SAMPLETABLE  (COL1   CHAR(6)      NOT NULL,   COL2 VARCHAR(24)  NOT NULL)"
DB20000I  The SQL command completed successfully.

插入一个虚拟行；

user@host:/home/db2inst1:>db2 "insert into SAMPLETABLE VALUES ('test1','test2')"
DB20000I  The SQL command completed successfully.

这是出口；

user@host:/home/db2inst1:>mkdir data   
user@host:/home/db2inst1:>cd data/
user@host:/home/db2inst1/data:>db2move sampledb export

Application code page not determined, using ANSI codepage 819

*****  DB2MOVE  *****

Action:  EXPORT

Start time:  Mon Jul 18 17:49:49 2016


Connecting to database SAMPLEDB ... successful!  Server : DB2 Common Server V10.5.7

EXPORT:    147 rows from table "SYSTOOLS"."HMON_ATM_INFO"
EXPORT:      0 rows from table "SYSTOOLS"."HMON_COLLECTION"
EXPORT:      5 rows from table "SYSTOOLS"."POLICY"
EXPORT:      1 rows from table "DB2INST1"."SAMPLETABLE"

Disconnecting from database ... successful!

生成ddl。

user@host:/home/db2inst1/data:>db2look -d sampledb -e -a -o db2look.sql
-- Generate statistics for all creators 
-- Creating DDL for table(s)
-- Output is sent to file: db2look.sql
-- Binding package automatically ... 
-- Bind is successful
-- Binding package automatically ... 
-- Bind is successful



user@host:/home/db2inst1/data:>db2 terminate
DB20000I  The TERMINATE command completed successfully.

这是第二个数据库。

user@host:/home/db2inst1/data:>db2 "create db copydb"
DB20000I  The CREATE DATABASE command completed successfully.


user@host:/home/db2inst1/data:>db2 "connect to copydb"

   Database Connection Information

 Database server        = DB2
 SQL authorization ID   = DB2INST1
 Local database alias   = COPYDB

在 db2 中更改数据库名称如下所示

CONNECT TO COPYDB;


user@host:/home/db2inst1/data:>db2 -tvf db2look.sql 
CONNECT TO COPYDB

   Database Connection Information

 Database server        = DB2
 SQL authorization ID   = DB2INST1
 Local database alias   = COPYDB


CREATE SCHEMA "DB2INST1"
DB20000I  The SQL command completed successfully.

CREATE TABLE "DB2INST1"."SAMPLETABLE"  ( "COL1" CHAR(6 OCTETS) NOT NULL , "COL2" VARCHAR(24 OCTETS) NOT NULL ) IN "USERSPACE1" ORGANIZE BY ROW
DB20000I  The SQL command completed successfully.

COMMIT WORK
DB20000I  The SQL command completed successfully.

CONNECT RESET
DB20000I  The SQL command completed successfully.

TERMINATE
DB20000I  The TERMINATE command completed successfully.

您也可以使用导入而不是加载。

user@host:/home/db2inst1/data:>db2move copydb load

*****  DB2MOVE  *****

Action:  LOAD

Answer 2

感谢您的帮助，我得到了解决方案。如果其他人遇到同样的问题，请执行以下步骤： 1-创建要复制的数据库（在我的例子中是 BASESAT2） 2-在命令模式下使用 db2move，如下所示： db2move dbname COPY -sn SCHEMA_OF_YOUR_DBname -co TARGET_DB dbname_copy USER user_name USING password
