My production database is running on 8.1.6.0 .I created a standby and it was working fine for about a month .Today suddenly the production database went down where as the standby database was doing the managed recovery .

when I saw the alert log it show that arch ora 600 errors ..
The fix is to apply patch set 8.1.6.3 which the oracle support has said .

Till sunday I will not be able to do this since i have to bring other database also down .

What should i do to remove the link between the primary and the standby database

And have only the the primary database alone ..

I want to have only the primary database only for the time being ...
