Check Text ( C-29457r1_chk )
Determine if the Oracle Management Agent is installed: From SQL*Plus: select account_status from dba_users where upper(username) = 'DBSNMP'; If no rows are returned, this is not a Finding. If the DBSNMP account exists and the account_status is OPEN, then verify in the System Security Plan that operation and use of the Oracle Enterprise Manager Management Agent or another SNMP management program is documented and authorized. If it is not documented in the System Security Plan as being required, this is a Finding. If the DBSNMP account exists and the account_status is not OPEN, schedule the FIX action below then mark as not a Finding. Despite any justification or authorization, if a Management Agent is installed on a DBMS server that is in a DMZ and Internet facing, this is a Finding.

Fix Text (F-26519r1_fix)
Use the ORACLE_HOME/rdbms/admin/catnsnmp.sql script to remove all Oracle SNMP management agent objects in the database. Delete the executable file ORACLE_HOME/bin/dbsnmp or dbsnmp.exe if it exists from any Oracle Home not authorized for SNMP management. Uninstall any SNMP management agents installed on Oracle database servers installed in a DMZ that serve applications to Internet users. Uninstall any SNMP management agents that have not been authorized and documented in the System Security Plan. Document any authorized use of the SNMP management agent on database servers that do not support Internet applications in a DMZ in the System Security Plan. NOTE: Removal of SNMP management objects will prevent the ability to generate database statistics within Oracle Enterprise Manager.
