Installing Oracle SOA 11g

Published on by Advait11 Comments

Introduction:

In this post we will see detailed steps to install SOA 11g. The approach used in all 11g FMW components (Including SOA) is very different then 10g. The basic limitation of any 10g component involving infrastructure was that the product itself used to create database and configure the entire infrastructure. This used to put limitation on database port which always used to be 1521.

Here in 11g version, a user has a flexibility to use any port. 11g expects installed database as a pre-reqs and uses that database to create corresponding repository. This way we can have database and listener at any port and provide that information while creating repository.

Also another important feature with all 11g components is that web server used is weblogic and it is kept as another separate component in the form of pre-reqs. So any 11g components requiring web server expects weblogic as pre-reqs. With this brief introduction about 11g FMW components characteristics we will see the installation procedure for SOA 11g.

Installing SOA 11g:

Following are the brief steps for installing SOA 11g

1) Install database 11g (11.1.0.6 / 11.1.0.7) including configuring TNS and listener

2) Create repository using Oracle RCU (Repository Creation Utility)

3) Install WLS (weblogic Server) and create a middleware home

4) Install SOA 11g inside middleware home

5) Use config.sh or WLST to create and configure SOA domain and managed servers

In case of SOA 11g, BAM also gets install and configured if selected. Here we will install both SOA and BAM

Download Locations:

You can download all the required software from following location

Oracle Database 11g (11.1.0.6/11.1.0.7) – http://www.oracle.com/technology/software/products/database/index.html

Oracle SOA suite 11g – http://www.oracle.com/technology/software/products/middleware/htdocs/111110_fmw.html

Oracle RCU – http://www.oracle.com/technology/software/products/middleware/htdocs/111110_fmw.html

Oracle WLS 10.3.1 – http://www.oracle.com/technology/software/products/ias/htdocs/wls_main.html

Step 1) Install database 11g including configuring TNS and listener

For this you can refer previous post for database installation and create a 11g database. Also create a listener on any available port and configure TNS for the database.

Step 2) Create repository using Oracle RCU (Repository Creation Utility)

Using RCU, you can create repository for SOA. You dont have to install RCU for using it. RCU comes as a zip file which you need to unzip. Once you unzip you run <RCU_UNZIP>/bin/rcu binary

This will invoke a GUI. On the first page you can select “Create Repository” and click on next.

On the next page RCU will ask for database details in which you want to create the repository. The page will look as shown below

1

Once you connect to database, on the next page you need to select the repository that you want to create. Here you can select SOA as shown below. Metadata services will get selected automatically. Also you can use any prefix for these schema. All these schema created will have the prefix string prefixed to it. In this case it will prepend DEV before each schema name. Example DEV_MDS, DEV_SOAINFRA etc.

2

Once you click on next, it will show the summary and will create tablespace if they dont exists. After tablespace creation, click on create and it will create the required repository schemas.

Step 3) Install WLS (weblogic Server) and create a middleware home

Next step is to install WLS server. Carry out the basic installation of WLS. You need to provide a new location for middleware home when asked for as shown below.

wls1

Next it will ask for the location of weblogic. Here you can accept the default value as it will be created inside middleware home.

wls2

Select all other values as default and install WLS.

Step 4) Install SOA 11g inside middleware home

Installation of SOA home is again very straight. Installation of SOA will just lay down the file system, it wont configure anything. Important input while installing SOA is the middleware home location and location for SOA home

soa1

Here Oracle_SOA1 directory will get created inside mwhome directory. Rest of the inputs for SOA installation can be default.

Step 5) Use config.sh or WLST to create and configure SOA domain and managed servers

Once SOA installation is done, the last and the most important step is configuring SOA domain.

You need to navigate to <middleware_home>/Oracle_SOA1/common/bin location and run config.sh script. This script will open a new GUI window. Follow the below screen shots for configuring SOA.

soa2

Select all the required template from this screen. If you don’t need BAM installation, you can uncheck the Business Activity Monitoring template. Click on Next.

soa3

On the next screen give any domain name (soa_domain) in this case. You can keep the Domain location and Application location as default. These directories will get automatically created when this domain gets created at the end of installation. Click on Next.

soa4

On this screen, provide the weblogic password and click on Next.

soa5

On this screen you need to provide the database connection details like database name, hostname and database port. You also need to provide all the schema names and password you created using RCU. RCU will create exact 5 schemas required for SOA configuration. You need to provide details of those schemas on this screen. Once you click in next, the configurator will test the connection for all 5 schemas.

Once the connection test goes successful, you can keep rest of the values as default and create the required domain.

After domain creation start the weblogic server using <middleware_home>/user_projects/domain/<domain_name>/bin/startWeblogic.sh script

Also start the managed servers using <middleware_home>/user_projects/domain/<domain_name>/bin/startManagedWeblogic.sh script

You can then login to console using http://<SOA hostname>:<AdminServer port>/console

soa6

In the next post, I will provide the WLST details instead of config.sh for performing tasks in step 5) above.

Hope this helps !!

Spawn, Expect, Send and Interact

Published on by Advait3 Comments

Imagine a kind of automation you want to do where you want to telnet to a server within your shell script and carry out the activity on the remote server. There no RSH setup done on the remote server and you have to enter the password non-interactively. Under these kind of circumstances we have a tool called EXPECT.

expect is a unix command present under /usr/local/bin. In one of the scenario, I wanted to automate the installation Oracle Identity manager 9.1.0.1 (The install process will come in another post shortly). But Oracle Identity manager 9.1.0.1 is nither clonable nor it can be silently installed. Trust me, only way to install Oracle identity Manager is to do interactive installation using console mode of GUI mode.

But using expect commad we can simulate the complete installation non-interactively. Here we will see a small example of expect command.

As I said before expect is a binary present in /usr/local/bin directory and expect understand the command like spawn, expect, send and interact. These are the once that I used. Lets take a example where we want to telnet to a server and get the hostname and date (Just to verify that we connected to right server). I will provide the code and will explain the significance later.

#! /usr/bin/expect
spawn telnet mfgops;
expect "login:*";
send "cmsops\r";
expect "Password:*";
send "welcome\r";
expect "(cmsops) cmsops- ";
send "date;hostname;\r";
expect "(cmsops) cmsops- ";
send "exit\r";
expect eof;

Here is how you run this script and the expected output of the same.

-bash-3.00$ expect test.sh
spawn telnet mfgops
Trying 130.35.5.43...
Connected to mfgops.us.oracle.com (130.35.5.43).
Escape character is '^]'.

So we run the script using expect (expect test.sh) instead of using sh. You can even remove the expect and use ./ to run the script, but do not use sh, the script wont work.

spawn is used to spawn a command. A command which will expect some prompts.

expect us used to tell which prompts are expected. Here * is used as wild character, in case you are not sure about complete prompt.

send is used to send the inputs to those prompts. Example for login and password we send the appropriate inputs

interact is not used in this program, but in case you want the control back to the user, you can use interact.

We also have a expect module in perl which does almost similar kind of activities, but its more advanced than expect unix command. Expect.pm (perl module) is not installed by default, but you have to install it yourself.

I found this utility wonderful in case of automating something like telnet or any interactive console based installation. A very handy tool.

Hope this helps !!
