WebLogic Server (WLS) has several server cache directories it uses to store deployed applications and shared libraries. Each server (admin and managed) has its own cache directories named cache, stage and tmp. Sometimes these cache directories become stale and there can be a mismatch between what's running in memory and what's in the cache directory. This can cause various WebLogic Portal (WLP) issues such as NullPointerExceptions, broken portlets and deployment problems, to name a few. When experiencing these types of issues the first thing you should do is clear the cache directories to see if it resolves the issue.
This document explains how to clear the server cache directories (cache, stage, tmp).
