Oracle 8i? Really?
Why are you installing a version of oracle that hasn't been supported in this millenium, and is SEVEN major releases behind current? (8i, -> 9.1 -> 9.2 -> 10.2 -> 10.2 -> 11.1 -> 11.2 -> 12.1).
Now, to your question .... an error message with no context little better than no error message at all.
EXACTLY what did you do that resulted in this error? Exact commands, full commands, please.
In the absence of any context for the error . . . Let me google that for you
The error occurs due to various reasons.
If possible post the log here or create service request with Oracle support to debug.

Probably not going to get a lot of help from Oracle Support for an Oracle 8i problem.
