如何移动DB2的数据库建库目录

由于目录变化，需要将数据库从目录/home/db2inst1移动到目录/public/home/guanghong.yu/db2inst1

重新编目数据库

$db2 uncatalog db oracle

$db2 catalog db oracle

编目成功后会即可看到：

$db2 list db directory

Database alias = ORACLE

Database name = ORACLE

Local database directory = /public/home/guanghong.yu/db2inst1

Database release level = d.00

Comment =

Directory entry type = Indirect

Catalog database partition number = 0

Alternate server hostname =

Alternate server port number =

如上操作做了后仍然不能连接数据库，需要对表空间做如下操作：

编辑mvdb.cfg

DB_NAME=ORACLE

DB_PATH=/home/db2inst1,/public/home/guanghong.yu/db2inst1

INSTANCE=db2inst1

NODENUM=0

CONT_PATH=/home/db2inst1/db2inst1/NODE0000/ORACLE/T0000000/C0000000.CAT,/public/home/guanghong.yu/db2inst1/db2inst1/NODE0000/ORACLE/T0000000/C0000000.CAT

STORAGE_PATH=/home/db2inst1/,/public/home/guanghong.yu/db2inst1

运行如下命令：

$db2relocatedb -f mvdb.cfg

[db2inst1@hpserver2 db2]$ db2relocatedb -f mvdb.cfg

Files and control structures were changed successfully.

Database was catalogued successfully.

DBT1000I The tool completed successfully.

运行成功，数据库可以成功连接激活啦

[db2inst1@hpserver2 db2]$ db2 connect to oracle

Database Connection Information

Database server = DB2/LINUXX8664 9.7.5

SQL authorization ID = DB2INST1

Local database alias = ORACLE

OK，移动后的数据库可以被使用啦。
