you can use the two built in procedures which are used specifically for interrogating linked servers.
EXEC sp_tables_ex [OracleLinkedServerName] will get you started, but from there, you need to find a database/schema/table to really dig into:
EXECUTE sp_tables_ex
@table_server ='CPULinked',
@table_schema='BOOFILES',
@table_name = 'DOCTR'
EXECUTE sp_columns_ex
@table_server ='CPULinked',
@table_schema='BOOFILES',
@table_name = 'DOCTR',
@Column_Name ='DRTYPE'

Thanks for the tip!
Unfortunately, these queries returned empty result sets for me, though the server, schema and tables/views most certainly exist (and I can query them using OPENQUERY)
Actually what I was looking for was an equivalent to sp_help that I can run on Oracle. So something like:
select * from openquery(oracle, 'exec sp_help ''schema.table''')
replacing 'exec sp_help ''schema.table''' with whatever the equivalent is on Oracle.

ahh, sorry.
DESC or DESCRIBE TableName will get you some information, not sure how pretty it will be over a linked server, but that's what you want to try.

Doesn't Oracle have metadata views like ALL_TABLES, ALL_TAB_COLUMNS and ALL_USER_TABLES? Can you query those?

Alas, I don't think you can run DESC over OPENQUERY, since it is not a SQL command. I think you can only do that with the SQLPLUS command.Could be wrong though!
You are right.....it is an internal command that only works with SQLPlus.....shame though....

oracle has equivalent information_schema
Select * from all_tables
select * from all_views
Select * from all_tab_columns
***The first step is always the hardest *******
