With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you.

Oracle, Sever, 10.2.0.4, Development database on Windows

I have an Oracle database on my local Windows XP machine that I use for development and testing.

Up to now, I have done regular exports of selected schemas for backup purposes. Even though I have managed to automate this over the years, I still find it a bit tedious. It would be much easier to simply do a cold backup while backing up the rest of my files. I just use XCOPY to an external harddrive which works just fine.

The reasons for wanting a cold backup are:
* I don't have Oracle running at all times.
* I don't use ARCHIVELOGS.
* This is a personal test system.
* When recovery is needed, I start with a fresh XP or at least with a fresh Oracle installation.
* Creating a new instance, re-creating and importing all schemas is tedious and requires lots of manual work and thinking (the latter is the hard bit...).

In order to use the export approach, I have to make sure to start up Oracle as part of my backup procedure. This also takes time. In order to use XCOPY, I simply shut down the Oracle services as the first task in my backup script.

The idea is that I shut down Oracle and xcopy all my Oracle datafiles:
C:\oracle\product\10.2.0\oradata\ORCL\CONTROL01.CTL
C:\oracle\product\10.2.0\oradata\ORCL\CONTROL02.CTL
C:\oracle\product\10.2.0\oradata\ORCL\CONTROL03.CTL
C:\oracle\product\10.2.0\oradata\ORCL\REDO01.LOG
C:\oracle\product\10.2.0\oradata\ORCL\REDO02.LOG
C:\oracle\product\10.2.0\oradata\ORCL\REDO03.LOG
C:\oracle\product\10.2.0\oradata\ORCL\SYSAUX01.DBF
C:\oracle\product\10.2.0\oradata\ORCL\SYSTEM01.DBF
C:\oracle\product\10.2.0\oradata\ORCL\TEMP01.DBF
C:\oracle\product\10.2.0\oradata\ORCL\UNDOTBS01.DBF
C:\oracle\product\10.2.0\oradata\ORCL\USERS01.DBF

as well as the spfile
C:\oracle\product\10.2.0\db_1\database\SPFILEORCL.ORA

There is lots of information on the net about backing up Oracle but it's mostly about 24/7 databases and all recommendations are to use hot backups. This is not needed in my scenario. I was not able to find simple consistent information how to recover a backup like the one mentioned above.

Questions:
1. Do I need any other files to be able to restore?
2. Do I need to export a pfile or can I use the spfile?
3. How do I recover the database on a fresh installation of Oracle suing the files as above?
