Question: I am trying to start Oracle Enterprise Manager (OEM) and I get the error "page not found".
What are the possible reason that OEM would produce a page not found error?
How can I fix the page not found problem?
Answer:
The "page not found" error is common on OEM when a PATH variable is missing, or when an OEM component is not properly installed.
To fix the "page not found" error on Oracle OEM, try this:
- Verify the registry entries for $ORACLE_HOME and ORACLE_SID
- Ensure that your listener is running with lsnrctl, and restart the listener if needed:
c:\lsnrctl stat
- Verify your Oracle connectivity with SQL*Plus:
c:> sqlplus nolog myuser
- Drop your existing OEM configuration (from the DOS prompt using emca):
c:> set ORACLE_SID=mysid
c:> emca -deconfig dbcontrol db -repos drop
- Recreate the EM environment with emca:
c:> emca -config dbcontrol db -repos create
