Do you need licences from the start?
• No, you do not
• You need licence(s) when
– You need HA options
– You need management pack options
Architecture / Planning
sysco.no
Check – Do you need a separate test and production environment?
• Pros
– Only possible solution when there are separate network zones
– Can test patches in test environment
• Cons
– Higher cost for maintenance and hardware
– Cannot verifiy every patch first, but do you need it?
Architecture / Planning
sysco.no
Check – Where is your service desk?
• Will all be handeled in EM ?
• Do you have external systems for this?
– Nagios
– HP
– Remedy
• This is handeled by Connectors or custom
Architecture / Planning
sysco.no
Check – Is there any ITIL requirements?
• EM fits the ITIL vocubulary well
• There is good support for compliance rules / framework
Architecture / Planning
sysco.no
Check – Will you use an LDAP service?
• You can have a user base in EM, but we recommend only for a small
set of users
• If you have LDAP in place, we recommend using it
• This will need some setup on the LDAP service
• Use personal users – not SYSMAN
Architecture / Planning
sysco.no
Check – Do you have any OS requirements?
• We recommend Oracle Enterprise Linux
• But others work too
Architecture / Planning
sysco.no
Check – Can you run this virtual?
• Recommended is dedicated physical environment
– For redundancy: ODA X4-2
• For virtual environment we recommend OVM
– Not on same virtual environment as the rest (separate OVM Manager)
• Licencing is not an issue, so use a fast server – recommendation is 32GB RAM,
minimum 16GB RAM
• Check that your disk is not slow
• Our recommendation is the simplest choice: Run DB and EM on same node
Architecture / Planning
sysco.no
Check – Do you need HA?
• HA will require HA on database, and you will have to licence the database
• HA will require a more complex installation procedure
• For clustered install, Oracle Database Appliance is an option
• If you are not sure, plan for HA or growth
– for example configure a virtual host name
– use the middle size option instead of small

• Do get too many notifications
– Stop those not relevant
