  3. Specify the action you want to perform:

  5. Press ENTER to run the process.

Tip: To see a quick help on the switches available for the /snapshot operation, type the following:

"C:\Program Files\Devart\dbForge Schema Compare for Oracle\schemacompare.com" /snapshot /?

Additional arguments:

You can edit the generated file to add some additional parameters, for example:

  • To write a comment, type:

      /comment:<value>
    
  • To apply compression to your snapshot file, type:

      /compress:[value]
    

To turn this option on, type Yes, Y, On, True, T.

To turn this option off, type No, N, Off, False, F.

  • To specify full connection string with additional parameters, type:

      connection:<connection_string>
    

    This argument is required.

  • To specify a file name and its path to save the created snapshot file, type:

      /file:<file_path>
    

    If the path is not specified, the snapshot will be saved to the current directory.

  • To specify server password, type:

      /password:<pw> 
    

Define this argument to override the password specified in the connection string.

Command line used to make a snapshot of a schema may look like:

"C:\Program Files\Devart\dbForge Schema Compare for Oracle\schemacompare.com" /snapshot /connection:"User Id=hr;Server=ORCL;Unicode=True;" /password:my_pass /schema:"HR" /file:"result.snap"

If you connect to the server in the Direct mode, the connection parameters will differ and the command line used to make a snapshot of a schema will look like:

"C:\Program Files\Devart\dbForge Schema Compare for Oracle\schemacompare.com" /snapshot /connection:"User Id=hr;Server=dbOracle;Connect Mode=SysDba;Unicode=True;Direct=True;Service Name=ORCL" /password:my_pass /schema:"HR" /file:"result.snap"
