From ctrassens@yahoo.com Thu, 04 Oct 2001 02:43:50 -0700 From: Christian Trassens Date: Thu, 04 Oct 2001 02:43:50 -0700 Subject: Re: "CI" locks In-Reply-To: Message-ID: MIME-Version: 1.0 Content-Type: text/plain It's a kind of lock that appears on Parallel Server. However, it happens without it when buffers are flushed for reuse. F.e., during a truncate table. Also with applications that uses dbms_pipe this contention could be usual, because of the processes queue up for blocks on buffers. It is recommeded to increase the shared pool. However, if it is sporadic and "nobody" is hurt, I won't change it. Are you using Applications ?.
