I have run the post install as both dbo and sa, and I am seeing missing tables that are in the Appendix A, but not in the database either through Catalog or Management Studio.
The missing tables:
Read/Write
JTX_TRANSACTION_SESSIONS
JTX_TRANSACTIONS_TEMP
JTX_TRANSACTIONS
JTX_STEP_COMMENTS
Read
JTX_LAYERS
JTX_JOB_TYPE_MAP_DOC
