oracle export data (data pump)
Goal: to export oracle database instance is wan, all the operational data table for the next user wan_y dmp file
Note: The syntax expdp with exp bit different, expdp need a logical directory to store the dmp file (I could not thoroughly understand.) this directory can create your own logic. How to create your own Baidu, here comes the logical directory
su - oracle
sqlplus / AS sysdba
the SELECT * from dba_directories; : View oracle logical directory create yourself
Exit
expdp wan_y / wan_y @ WAN schemas = wan_y dumpfile = = DATA_PUMP_DIR gong.dmp Directory
user / password @ instance name schemas = username dumpfile = export file name (dmp format) directory = logical directory name
