Lindon, We have had a controller card go intermittently hay-wire and corrupted the database. It even caused corruption to read-only tablespaces. It is quite possible to corrupt Oracle read-only files with an os or hardware problem. A good backup procedure was the saving grace for that one. Currently I am attempting to diagnose slowdowns in logging into the database. Normal connect time is < 3 seconds. During slow downs connect > 60 seconds. All indication so far point to memory problems or controller problems. Difficult to trouble shoot without tools built for the os. (Novell). It takes a lot of paging through the os displays before and after the trouble occurs. A reboot of the system clears the trouble for a week or so. Ron

Second time - no idea. Oracle Support said they'd need mounds of info from the o/s and even then they may not be able to explain it. Since I didn't have the time to gather all the necessary info we let it go. What a lovely thought for a Friday afternoon. At least my databases aren't corrupted.

Anyways, the problem was traced to a corrupted Oracle database (as to whether the tables or the data file got corrupted. how and why - a $$$ consultant is trying to find out). How could an Oracle database get corruppted in the first place? Anyone here with an experience of their Oracle database getting corrupted and what caused it and what was done to fix it? -- Lyndon Tiu Quoting DENNIS WILLIAMS <[EMAIL PROTECTED]>: > Lyndon > I would look at the wait statistics to see what is happening inside > Oracle.
