If these alerts are creating “white noise” for your DBA Group, please
consider using one or more methods to properly silence the noise. This is
a six part blog post, (which the bellow link is only one of) but should
help you get a handle on the alerting and address it for the affected
targets.

We are running EM 12.1.0.5. For the past several months, since upgrading
our agent to 12.1.0.5, across various databases we have been receiving a
blocking alert warning with the blocker being LGWR. By the time you log on
the database directly or through Enterprise Manager, no blocking locks can
be found. In fact, sometimes no active sessions are found or run quickly.
After about 15+ minutes the alert clears.
We do correctly receive the alert on user sessions that are causing a
locking condition.
Is there a way to bypass LGWR?
