Page Not Found on OEM Tips

Expert Oracle Database Tips by Donald BurlesonApril 22, 2015

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:

  1. Verify the registry entries for $ORACLE_HOME and ORACLE_SID

  2. Ensure that your listener is running with lsnrctl, and restart the listener if needed:

    c:\lsnrctl stat

  3. Verify your Oracle connectivity with SQL*Plus:

    c:> sqlplus nolog myuser

  4. Drop your existing OEM configuration (from the DOS prompt using emca):

    c:> set ORACLE_SID=mysid
    c:> emca -deconfig dbcontrol db -repos drop

  5. Recreate the EM environment with emca:

    c:> emca -config dbcontrol db -repos create
