2 Installation steps (overview)
Oracle 12c service bus installation steps require diverse
components to be installed in a series of steps. Details for each step will be
added on the next sections, however the following items list the specific order
to be followed when performing this installation.
·
Install JDK
·
Install Oracle database
·
Install fmw infrastructure
·
Install fmw service bus
·
Execute RCU database scripts
·
Create/Update weblogic domain
This guide will provide step by step instructions required
when installing a development environment with only 1 admin server and 1
managed server. However these steps could easily be adjusted for 2 or more
managed servers. Additionally in order to simplify this development environment,
the database being used is Oracle XE which is not officially supported but
works for this purpose.
3 Install JDK
Make sure you have downloaded oracle open jdk. Oracle
edelivery site contains this and the rest of the required software components.
If you get this jdk from oracle consider rpm packaging and extract as follows
rpm -ivh jdk-7u55-linux-x64.rpm
now use the following commands to make this java your
default
alternatives --install
/usr/bin/java java /usr/java/jdk1.7.0_10/bin/java 2
alternatives --config java
test your java installation with java -version , the command output
should show something like
java version "1.7.0_55"
Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed
mode)
4 Install Oracle XE database
The XE database installation is really
straightforward therefore just extract the rpm package with the command unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip,
then navigate to the subdirectory Disk1 and
then execute rpm -ivh oracle-xe-11.2.0-1.0.x86_64.rpm
The installation will ask you to execute the following
command with root user. Open a different terminal window and execute with root
user
/etc/init.d/oracle-xe
configure
accept all the defaults except for the password, in my case
I used oracle.
Now restart your system just to make sure Oracle XE is
running when the system starts, and proceed to the next step.
5 Install fmw Infrastructure
execute the command java
-jar fmw_12.1.3.0.0_infrastructure.jar
click ok to set the oracle inventory directory. Now set the
middleware home, for simplicity in my case I used /home/oracle/Oracle/Middleware/Oracle_Home
For the installation type pick the option Fusion Middleware Infrastructure, at
this moment we don't need the examples. Installation will check all the
prerequisites are met. Check the remaining default options and then Install.
at the end you should see a successful screen as the
following.
6 Install OSB
In a similar way as the infrastructure installation execute the
osb software installation with a command as follows java -jar fmw_12.1.3.0.0_osb.jar
Click next to preserve the same oracle inventory directory.
When asked for the oracle_home use the previously created oracle_home. In my
case this is /home/oracle/Oracle/Middleware/Oracle_Home
Click next on the following default options until
installation completes.
7 Execute RCU database scripts
Now that the infrastructure has been installed is time to
create the corresponding database schemas.
Make sure JAVA_HOME variable is set, in my case this was set as
export JAVA_HOME=/usr/java/jdk1.7.0_10
Navigate to the directory [Oracle_Home]/oracle/common/bin and execute the rcu creation script
as ./rcu
Click next and select create
repository / System load and product load.
Now set the Oracle database XE connection parameters, make
sure to use an oracle database account with sysdba privileges such as SYS.
Click next and then ignore the alert message acknowledging
XE is not supported. This will still work, obviously for a production system
use a fully supported Oracle database.
Select the database schemas shown below. You can use a
different database prefix if you want, as long as you remember it at the moment
of the domain creation.
click next and set the password to be used for each of these
database schemas. In my case and for demonstration purposes I use oracle.
Now click next and accept to create the tablespaces.
Click on create and at the end a successful creation screen
will show.
8 Create weblogic domain
The first thing is to create a generic weblogic domain that
includes only OWSM and is only attached to the AdminServer. Don't create any
managed server at this point. To execute
the shell script for the weblogic domain creation execute ./Oracle/Middleware/Oracle_Home/oracle_common/common/bin/config.sh
The first thing to do is set a domain name and location, in
my case the domain name will be osbdomain
and the location /home/oracle/Oracle/Middleware/Oracle_Home/user_projects/domains/osbdomain.
Now select the components to be installed for this domain,
the below screenshot shows the detail. Also note Oracle Service Bus isn't
selected. This will make sure OWSM is installed properly without messing up
with OSB components.
click next and when asked for the domain credentials set
them and take note for future references. In my case I used weblogic for user name and weblogic1 as the password.
Now select the option Development
for domain type, also make sure jdk location is properly set and click next
On the next screen fill in all the database parameters and
then click on Get RCU Configuration
button.
click next and wait until all the database schemas have been
tested. On the following screen select Administration
Server and then next.
For the Administration Server configuration, fill in the
listen address with your hostname in my case is osbhost. For the listen port
you can use the default 7001. For the server groups choose JRF-MAN-SVR, WSM-CACHE-SVR, WSMPM-MAN-SVR.
Click next and then create. Wait until domain creation ends.
Now your domain is created and a successful screen will show
up.
The domain can be verified by starting up the administration
server with ./Oracle/Middleware/Oracle_Home/user_projects/domains/osbdomain/bin/startWebLogic.sh
Once it has started login with a web browser using
a url following the pattern http://[hostname]:[listen port]/em such as http://osbhost:7001/em. If your hostname and/or port is different use
that instead.
9 Update weblogic domain to include OSB components
Before updating any weblogic domain make sure the
Adminserver isn't running. To execute the shell script to update a weblogic
domain do ./Oracle/Middleware/Oracle_Home/oracle_common/common/bin/config.sh
Note this script is the same used when the
weblogic domain was initially created. On the first screen select the option
update and select the domain previously created, in my case this is osbdomain.
Now select the osb required components as shown on the next
screenshot.
click next and on the next screen the osbdomain database
parameters should be populated. Confirm the values and click next.
click next in order to test the database connections.
click next and select the option managed servers, clusters and coherence.
Now fill in the osb server values such as osb server name
(osb_server1 for me), listen address (osbhost for me), listen port (7003 for
me). Also verify the group OSB-MGD-SVRS-COMBINED is chosen.
click next, skip cluster configuration due we are creating
only one managed server. Click next and leave the default options for coherence
clusters. On the Machine configuration screen click on the tab Unix Machine and then on the Add button. Fill in the unix machine
settings. In my case I set LinuxMachine1 as machine name, osbhost as node
manager listen address, and 5556 as node manager listen port.
Click next and on the following screen use the blue arrow to
assign the servers to the unix machine.
Click on the update
button and wait until domain finishes the updating process.
Domain successful update screen will show.
In order to test the domain first start the admin server
from a linux terminal and then on a different terminal start the managed
server. Use the following commands
./Oracle/Middleware/Oracle_Home/user_projects/domains/osbdomain/bin/startWebLogic.sh
./Oracle/Middleware/Oracle_Home/user_projects/domains/osbdomain/bin/startManagedServer
osb_server1
Now login to the EM console in http://osbhost:7001/em and
verify the installation.
10 Additional steps
·
When login into the weblogic domain console
using a url such as http://osbhost:7001/console and clicking on deployments you
will notice the following applications are shown with a warning symbol next to
them. To fix this remove the AdminServer as a target for the following
applications
o
Service Bus SFTP Transport Provider
o
Service Bus FTP Transport Provider
o
Service Bus Email Transport Provider
o
Service Bus File Transport Provider
Appendix A
Possible roadblocks and solutions
·
If the exception Too many open files is raised then edit /etc/security/limits.conf
file and set hard and soft options for the oracle account, for example oracle soft nofile 50000.
·
if working in a virtualbox environment and
access to shared folder for the oracle account is required. Use the root
account to provide access as follows usermod
-aG vboxsf oracle
