RE: alter system reset

On a Unix system, you can "tput reset" to clear up that mess after viewing a binary file by accident.

Using an editor to view the binary file is a much better idea than displaying it directly to the screen. Doing so with a binary file will often corrupt the display.

All that is needed is to close the window and open a new one, but that is kind of a pain at times as you lose your command history.

Prem,

The SPFILE should never be opened to be modified; opening a file to see the contents are acceptable and that's what I said. Sometimes opening the file in an editor may not be needed;
"type" in Windows command prompt or "cat" in unix will let us achive the same objective.

Talking about the SPFILE modification, you can't effectively modify it with accuracy. The file is binary (actually binary in the beginning and then text towards the bottom part), so even if you open it in notepad and save it, there is no guarantee that the file will be accurately saved with all contents intact.

By the way, I have edited the SPFILE in some cases, only in development, though; but I wouldn't advise it to be done that way; always use ALTER SYSTEM ... SCOPE=SPFILE to modify it or edit the init.ora file and then create the SPFILE from it. You can create the spfile from pfile even when the instance is down.

HTH. Arup
