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。
