Hi I am new and I am used to MS SQL Manager’s Attach/Detatch functionality

  • 0

Hi I am new and I am used to MS SQL Manager’s Attach/Detatch functionality to drop a database into a single file so I can move it to other computers/SQL instances. In a nut shell, this is what I want to do.

I have a large Oracle Express database (instance name Zeus) that I need to move onto other Oracle Express instances (brand new installs) and then later I need to keep them updated with Zeus’ database.

How do I do this? I am not understanding how to export the database/schema – user definition/permission, table definitions, and table data.

Thanks guys

  1. I don’t believe you can easily do that with Oracle (especially XE edition).

    You would usually do an Import/Export. This would give something like :

    expdp system/password@XE DUMPFILE=expfull.dmp FULL=y
    impdp system/password@XE DUMPFILE=expfull.dmp FULL=y

    The expfull.dmp files would be located in a folder named oradata/dpdump in the Oracle XE installation.

    You could also use Transportable Tablespaces as described here and summarized here.

    Another method involves 10 steps and would have to be adapted to Oracle XE. I mention it here for reference.
