Oraagent many SYSRAC processes open
These are internal, background processes connecting Oracle RAC Database with Oracle Grid Infrastructure High Availability Services. You can't control them. The status of &quot;INACTIVE&quot; can be misleading; it doesn't mean they don't have a purpose or aren't actually doing anything. Any background or user session will show as &quot;INACTIVE&quot; unless it is actually performing an operation that takes long enough to be recognized from one monitoring cycle to the next, at the exact moment you happen to query gv$session.
What &quot;connection pool&quot; are you trying to grow? These background processes should not count against most application-level pools or limits.
