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
files and control structures were changed successfully.
database was catalogued successfully.
dbt1000i  the tool completed successfully.
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。
