You're ready to finalize the apps tier configuration when the testing of the database startup and shutdown
process is completed. At this moment, the e-Business Suite configuration on the application tier server is unaware of
the changes in the database tier; that is, Net services and JDBC configuration is still set for a single-node database and
needs to be adjusted for the RAC database.
As expected,
AutoConfig
is capable of adjusting the configuration and the process is well explained in the “4.7.
Establish Applications Environment for Oracle RAC” section of My Oracle Support note “Using Oracle 11g Release
2 Real Application Clusters and Automatic storage management with Oracle E-Business Suite Release 12.2 (Doc ID
1453213.1).” Here's a quick summary of the steps:
1.
Adjust the
tnsnames.ora
and the JDBC URL in the context file manually to allow
connectivity to one of the database instances of the RAC-enabled database.
2.
Run
AutoConfig
on the applications server to retrieve the configuration information from
the database, and then write the necessary changes to the configuration files.
3.
Update the JDBC URL from in the Weblogic Server data source.
This concludes the database migration to ASM and RAC. You've made it through the most complicated
part—implementing e-Business Suite on ODA. At this moment, you have a fully functional system with two nodes
in the database tier and one node in the application tier. The next section of this chapter will show you how to
clone the application tier VM and implement the second application tier node using the shared application
tier file system.
Clone the Application Tier VM
At this moment, you have only one virtual machine running the e-Business Suite application tier. Fortunately,
it's very easy to clone a new VM on the ODA from an existing one, and doing so will give you a VM that is already
preconfigured the for the existing environment. Create a VM template from the existing VM, and clone the new
VM from the new template. Additionally, you'll have to change the hostname and the IP address. Let's take a more
detailed look at how to accomplish this process:
1.
Stop the e-Business Suite services. Make sure they are not running during the cloning
process to follow.
2.
Stop the existing VM (oevm1) by connecting to one of the ODA Base servers and running
oakcli stop vm
, as shown next. Follow by executing
oakcli show vm
to confirm when the
VM shuts down.
[root@s1 ~]#
oakcli show vm
NAME MEMORY VCPU STATE REPOSITORY
oevm1 12288 4 ONLINE odarepo1
[root@s1 ~]#
oakcli stop vm oevm1
Shutdown VM initiated for oevm1

oakcli show vm
