DB2数据迁移之db2lock/db2move
1.模拟带有identity表
[db2inst1@xifenfei ~]$ db2 "create table t_xff(xid smallint not null generated always as identity
> (start with 1,increment by 1),x_name varchar(200))
in
ts_xifenfei"
DB20000I The SQL
command
completed successfully.
[db2inst1@xifenfei ~]$ db2
"insert into t_xff(x_name) values('www.xifenfei.com')"
DB20000I The SQL
command
completed successfully.
[db2inst1@xifenfei ~]$ db2
"insert into t_xff(x_name) values('XIFENFEI')"
DB20000I The SQL
command
completed successfully.
[db2inst1@xifenfei ~]$ db2
"insert into t_xff(x_name) values('xifenfei')"
DB20000I The SQL
command
completed successfully.
[db2inst1@xifenfei ~]$ db2
"select * from t_ff"
SQL0204N
"DB2INST1.T_FF"
is an undefined name. SQLSTATE=42704
[db2inst1@xifenfei ~]$ db2
"select * from t_xff"

2.导出表结构
[db2inst1@xifenfei ~]$
mkdir
move_s
[db2inst1@xifenfei ~]$
cd
move_s/
[db2inst1@xifenfei move_s]$ db2look -d sample -e -l -o db2_sample.ddl
-- No userid was specified, db2look tries to use Environment variable USER
-- USER is: DB2INST1
-- Creating DDL
for
table(s)
-- Output is sent to
file
: db2_sample.ddl

3.导出数据
[db2inst1@xifenfei move_s]$ db2move sample
export

4.目标端创建数据库
C:\Windows\system32>db2
"create db db_XFF pagesize 8 k"
DB20000I CREATE DATABASE命令成功完成。

5.目标端创建对象
C:\Windows\system32>DB2 -tvf D:\move_s\db2_sample.ddl -l d:\xifenfei.log
--检查xifenfei.log文件,发现错误,手工修复

6.导入数据文件
D:\move_s>db2move db_xff load
***** DB2MOVE *****

7.重新导入identity表
D:\move_s>db2 connect to db_xff
数据库连接信息
数据库服务器 = DB2
/NT
9.5.0
SQL 授权标识 = XIFENFEI
本地数据库别名 = DB_XFF
D:\move_s>DB2
"load from tab19.ixf of ixf modified by identityoverride insert into db2inst1.t_xff"
SQL3501W 由于禁用数据库正向恢复，因此表所驻留的表空间将不被置于备份暂挂状态。
SQL3551W 表至少包含实用程序将覆盖的一个 GENERATED ALWAYS 列。
SQL3109N 实用程序正在开始从文件
"D:\move_s\tab19.ixf"
装入数据。
SQL3500W 在时间
"2012-04-15 23:06:52.393775"
，实用程序在开始
"LOAD"
。
SQL3150N PC
/IXF
文件中的 H 记录具有产品
"DB2 02.00"
，日期
"20120405"
和时间
"202132"
。
SQL3153N PC
/IXF
文件中的 T 记录具有名称
"tab19.ixf"
，限定符
""
和源

。
SQL3519W 开始装入一致点。输入记录数 =
"0"
