Analyzing an Oracle dump I have a full Oracle dump, I know I have to imp the dump with the fromuser touser clause.

However, I don't know the names of the schemas included in the dump.  How can I open the dump created with Oracle 10g just to check and analyze the content?
Use the SHOW=Y option for imp

From the manual at http://download.oracle.com/docs/cd/B19306_01/server.102/b14215/exp_imp.htm#sthref2498


  When SHOW=y, the contents of the export dump file are listed to the display and not imported. 
  The SQL statements contained in the export are displayed in the order in which Import will execute them.
  The SHOW parameter can be used only with the FULL=y, FROMUSER, TOUSER, or TABLES parameter.
