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
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

重新编目成功，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。
