由於目錄變化，需要將資料庫從目錄/home/db2inst1移動到目錄/public/home/guanghong.yu/db2inst1

重新編目資料庫

$db2 uncatalog db oracle
$db2 catalog db oracle

編目成功後會即可看到：
$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         =

如上操作做了後仍然不能連線資料庫，需要對錶空間做如下操作：
編輯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
執行如下命令：
$db2relocatedb -f mvdb.cfg
[

[email protected] db2]$ db2relocatedb -f mvdb.cfg
Files and control structures were changed successfully.
Database was catalogued successfully.
DBT1000I  The tool completed successfully.
執行成功，資料庫可以成功連線啟用啦
[[email protected] db2]$ db2 connect to oracle

   Database Connection Information

 Database server        = DB2/LINUXX8664 9.7.5
 SQL authorization ID   = DB2INST1
 Local database alias   = ORACLE
OK，移動後的資料庫可以被使用啦。
