DB2移动数据库目录调整方法

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。
