• .
Slide 10
EM12C Architecture
Suggestions
• Setup an additional / separate OMS for Dev/QA targets
• Setup Level 3.5 Maximum Availability Architecture (MAA)
• Multiple Sites
• Multiple OMS (Primary / Standby)
• Oracle Data Guard with Fast Start Failover setup.
• Using VIP’s / DNS alias help with data Guard rollover.
• Use Load Balancer (optional) for OMS.

sites.
Create Data Guard database on other
site.
NFS Shared Library
Primary OMS Setup
Plugins Installed on Primary Site
Slide 15
Pre-requisites for High Availability
• Optional setups:
• Fast Start Failover Data guard
Setup(Requires additional hardware)
• Load Balancer NOT REQUIRED –
Although the documentation disagrees
• RAC DB’s– Great if you can afford it.
Slide 16
Requirements Standby OMS
• Machine Required for Standby OMS/DB
(Linux, Sparc, HPUX, Microsoft)
• Plugins need to be the same version
• Exact same directory structure
• Load Balancer (optional)
• NFS Drive ….
Slide 17
Configuration Steps:
1.Install Primary OMS / DB
2.Add targets to Primary
3.Setup NFS Drive – Software Library
4.Add All Plugins required to Primary OMS
5.Add Dataguard - Standby Database
6.Create Standby OMS
7.Convert Standby Database to RAC (IF Available)
Slide 18
Installation Steps: (Silent)
 Verify NFS Software Library on Standby Machine
 Install a “Software-Only” Installation on Standby OMS
Machine
 (Do NOT run the ConfigureGC.sh or ConfigureGC.bat)
Slide 19
Installation Steps: (Silent)
•
Ensure same Plugins as the source OMS

Slide 21
Installation Steps: (Silent)
Plug-ins (Continued)
1. To Install Additional Plug-ins – Manually download the
plug-ins from OTN to Accessible location (i.e., /tmp)
a. Verify that they are the same version as primary OMS
2. http://www.oracle.com/technetwork/oem/gridcontrol/downloads/index.html
3. Run $OMS_HOME/sysman/install/PluginInstall.sh –
pluginLocation /tmp - Choose the plugins you want to
install (screen print – next page)
Slide 22
PluginInstall.sh
Slide 23
Installation Steps: (Silent)
1. Apply all patches that were applied to the first OMS
a. To Check - $OMS_HOME/OPatch/opatch lsinventory
2. Export the Configuration Details from the First OMS
a. $OMS_HOME/bin/emctl exportconfig oms –dir <Path
Name>
b. Creates bka file – i.e. opf_ADMIN_<DATE>_<TIME>.bka
c. Copy bka file to standby OMS Machine
Slide 24
Installation Steps: (Silent)
oracle@pr2prodora01 ~]$ cd /u01/app/oracle/OracleHomes2/oms/bin/
[oracle@pr2prodora01 bin]$ ./emctl exportconfig oms -dir $HOME

!!! Many errors at this stage, due Failed attempts
Slide 28
Installation Issues:
MSEVERE: OMSCA-ERR:Post "Deploy and Repos
Setup" operations failed
Check the following items :
-- Check RAM on Standby Machine – needs 6GB – to Install
-- If using 32 Bit Linux –
Modify – create_domain.py (under omsca/scripts/wls
directory)
Change - -Xmx1524m to –Xmx1324m
Change –XX:MaxPermsize=612M to –X:MaxPermsize=412M
-- Check for Lock in repository
Slide 29
Installation Issues
•
•
Check for lock in the repository
Due to multiple tries there was a lock in the
repository during the plugin deployment stage.
•
•
•
select host_url, oms_id, status, is_first_oms,
em_release_version from gc_oms_info;
select mp_guid,file_id,file_name,file_type from
mgmt_mp_files;
select * from em_plugin_lock_track;
Slide 30
Installation Issues:
•
First Issue – wrong version of the database plugin
•
•
I upgraded the database plugin but didn’t include it
in the standby installation
Copied latest “DB” plugin and reran
pluginInstall.sh
Slide 31
Installation Issues:
•
2nd Issue – Plugin Issue and multiple attempts
caused lock in EM database (SYSMAN)
•
•
•
Removed record from lock table
em_plugin_lock_track
Ran $OMS_HOME/bin - ./pluginca –action deploy
–isFirstOMS false –plugins
Started OMS
Slide 32
Final Installation Steps
 If you haven’t installed the agent on the standby
host:
$<AGENT_HOME>/sysman/install/agentDeploy.sh
AGENT_BASE_DIR=<middleware_ home>/agent
OMS_HOST=<second_oms_host_name> EM_UPLOAD_PORT=<second_oms_
port> AGENT_REGISTRATION_PASSWORD=<password> -configOnly
Note: If you have Server Load Balancer (SLB) configured, then directly
enter the host name and port number of the SLB. If SLB is not
configured, then enter the secure upload port of the first OMS.
Slide 33
Final Installation Steps

After agent is installed and deployed
•


Deploy the required plug-ins on the management agent
Secure the agent - $AGENT_HOME/bin/emctl secure
add_trust_cert_to_jks (If applicable)
In the new OMS Grid control (standby) – discover the Oracle Weblogic
services
•
•
•
Targets, Middleware, click EMGC_DOMAIN
From EMGC_DOMAIN home page
Select Farm Menu, Refresh Weblogic Domain, click continue till
2nd management server is discovered on the standby OMS Host.
