Slide 14

15. Pre-requisites for High Availability
• Setup VIP or DNS Alias for multiple
sites.
• Create Data Guard database on other
site.
• NFS Shared Library
• Primary OMS Setup
• Plugins Installed on Primary Site
Slide 15

16. 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

17. 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

18. 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

19. 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

20. 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/grid-
control/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

23. PluginInstall.sh
Slide 23

24. 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

26. Installation Steps: (Silent)
OMSCA Breakdown on Standby database using the
backup file created
• Uses the backup file just generated = bka file
• Admin Server HTTPS Port = 7101
• Managed Server Port=7202
• Managed Server HTTPS Port=7301
• EM Note Manager Port = 7403
• EM Upload Port = 4889
• EM Upload HTTPS Port=4900
• EM Console Port = 7788
• EM Console HTTPS Port= 7799
• Config_home = /u01/oracle/product/OracleHomes2/gc_inst
• EM_INSTANCE_HOST aa2prodora11.jstor.org (Standby machine)
Slide 26

27. Installation Steps: (Silent)
Of all these ports the following are relevant to the load
Balancer:
•EM Upload HTTP Port: 4889
•EM UPLOAD HTTPS Port: 4900
•EM Central Console HTTP Port: 7788
•EM Central Console HTTPS Port: 7799
Slide 27

28. Installation Steps: (Silent)
• Run OMSCA on Standby database using the backup
file created
<OMS_HOME>/bin/omsca recover -ms -backup_file
/opt/oracle/product/backup/opf_ADMIN_20120504_031016.bka

!!! Many errors at this stage, due Failed attempts
Slide 28

29. 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

30. 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

31. 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

32. 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

33. 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

34. 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.
