Hi Everyone,

This morning, I simulated loss of a datafile, and replaced it with a backup that is older than the control file. I did this in order to make sure that everything will work correctly when I need to recover the database for real.

I am glad I did this, because when I issued RECOVER DATABASE, I got the following error messages:

ORA-00308 cannot open archived log 'c:\ . . . .'

ORA-27047 unable to read the header block of file 001172.ARC

0SD -- 04006 Read File () failure, unable to read from file.

I am using Personal Oracle On a PC. The Oracle version is meant to run on Windows95; the computer uses Windows98; this initially caused installation problems which I overcame simply by repeating the installation attempts. Could the problem be connected to this mismatch?

Might this be an Operating System problem?

I would appreciate any insight into what the problem might be, and how to fix it.

Many thanks.

Cliff W.
