3. The Goal of Monitoring System
 Complete
 No “White Noise”
 Redundancy
 Escalation Process
 GUI Interface for Those Less Familiar
 Secure

4. Enterprise Manager 12c, the Cloud
 EM12c was announced at Oracle Open World,
Oct. 2011.
 EM12c was Oracle’s answer to business’ reach
into Cloud environments, which offers the ability
to setup, deliver and manage them.
 Administrators, through a single console, can
now monitor usage, setup metering,
chargeback for users, manage deployed
applications, manage issues and link
applications to MOS directly.
#Kscope

5. The Nitty-Gritty
 The full installer (OMS, Agent and Repository)
is available for Linux x86-64, Windows, Solaris
and AIX.
 The installation requires Oracle Weblogic
Server 10.3.5, which is included in the package.
 Installation does require an Oracle Database on
which Oracle Management Repository will be
configured. Version 10.2.0.5 and above are
supported.
 The EM12c manages databases from 9.2.0.8
and above.
#Kscope

6. The Nitty Gritty, Cont.
 Installation Rules
● The Oracle user does NOT require SUDO privs, (to
put security concerns at ease…) Any account with
SUDO privileges can run the root.sh script at the end
of the EM12c and agent installations.
● Port configuration in environments with more than
one EM, (i.e. running parallel with 10.2.0.5, such as
our environment) can run into port conflicts.
#Kscope

7. Licensing
 As long as the OMS is on its own server and is only
used for the OMS repository and/or an RMAN
backup catalog repository, individual oracle
licensing IS NOT required for the Oracle database
utilized for the repositories, (Please see pg. 15 of
the following PDF from Oracle.)
 Questions revolving dataguard installations, but
RAC is clear- you have to pay for RAC
installations of EM12c!
 http://download.oracle.com/docs/cd/B19306_01/lic
ense.102/b40010.pdf

8. The Repository:11.2.0.2
Ensure your redo logs are at least 300M each!
ALTER SYSTEM SET pga_aggregate_target=1G SCOPE=SPFILE;
ALTER SYSTEM SET shared_pool_size=600M SCOPE=SPFILE;
ALTER SYSTEM SET job_queue_processes=20 SCOPE=SPFILE;
ALTER SYSTEM SET log_buffer=10485760 SCOPE=SPFILE;
ALTER SYSTEM SET open_cursors=300 SCOPE=SPFILE;
ALTER SYSTEM SET processes=500 SCOPE=SPFILE; 1000!
ALTER SYSTEM SET session_cached_cursors=200 SCOPE=SPFILE;
ALTER SYSTEM SET sga_target=2G SCOPE=SPFILE;
EXEC dbms_auto_task_admin.disable('auto optimizer stats
collection',null,null);
#Kscope

9. Why Increase Processes in 11g?
#Kscope

10. Sysman Logins
 Ensure that the SYSMAN account is both
unlocked and set to a password that meets the
proper requirements, (over 8 characters, mixed
case, number and non-ascii characters.)
 Know that once the repository is created, there
will be sub-accounts supporting the SYSMAN
user, (SYSMAN_RO, SYSMAN_MDS, etc…)
These are REQUIRED to have the same
passwords set through the EMCTL commands
as the SYSMAN repository owner.

19. Adding Agents
 Auto-deployment is an easy, repeatable process that no
longer requires maintenance windows.
 No SUDO privilege is necessary for the Oracle user,
the root.sh can be run by any account with SUDO privs
or by the Unix Admin.
 A simple addition to the /etc/hosts file for the agent
server and the EM12c host server to each file is all that
is required.
 If on a Windows EM12c, deploying to a Unix/Linux
environment, Cygwin installation/configuration is
required.
