There is an error manual that you can get from the technet site which is published by Oracle. Many times these aren't very detailed.

Usually if the information is sparse, I do a search on Altavista like "ORA-3113" and usually I can sift through the pages and find information. I do have a metalink acccount (several actually *laugh*) but sometimes you can get good information outside of metalink as well. Another thing you might try is posting the error. It doesn't help if it's an emergency but someone on the board might be willing to go into Metalink for you and pull relevant documents.
