1. First of all run this query against the ebiz db that you are having a problem starting up the stat oracle agent and see if you have registered the product called AME.
SELECT fa.application_id id, fa.application_short_name app, fa.application_name, fpi.status, fpi.patch_level
FROM fnd_application_all_view fa, fnd_product_installations fpi
WHERE fa.application_id = fpi.application_id
N mean not installed
S mean shared
I mean installed
L mean custom
2. If AME product is not registered in your environment, but you might have ran the resource kit, which Stat is expecting this product to be registered in your environment. Try the following:
2a. Go to Maintenance | General | Object Types and select 'Oracle Apps Setup Objects' from the Object class list.
2b. Find AME object types and look for the type code column. Replace it with FND
2c. Click on the 'Setup' button. (AME Actions, AME Attributes and etc)
2d. Select R12 for version.(And also 11i)
2e. In the 'Type Code' field replace AME with FND.
2f. Do the same thing for anything that start with AME
2g. Now try to startup the stat oa again
