OSB-12C : Using Email transport protocol to send/receive email

-
Oracle service bus offers the Email transport for both receiving and sending e-mails.

 In this blog, I will show how we can set up a proxy service to listen on a mailbox for new e-mail messages. For each new e-mail message, the message processing as defined in the 
message flow of the proxy service is executed.


Prerequisite:
-----------------
In order to be able to receive e-mails on the OSB, we need a running mail-server. We could
connect to an already existing e-mail server, but for this recipe to be standalone, we will use
the Apache James mail-server. Perform the following steps for the installation of Apache James
on the local machine:

1. Download the latest version of Apache James binary from: http://james.apache.
org/download.cgi#Apache_James_2.3.2_is_the_stable_version.



2. Unzip the file into a local folder.

3. Navigate to the bin folder within the Apache James binaries.


4. Locate and execute the run.bat.


5. Open a command window and open a telnet session by entering telnet localhost
4555.

6. Enter root on the Login id prompt.

7. Enter root on the Password prompt.

8. Create a new user by entering the command adduser <user> <password>.

9. Create the osbuser and osbadmin user.Along with this for this use case i have created one more user called 'testuser'.

10. List the users by entering the listusers command.



11. Enter quit to exit the telnet session and close the command window.

Now, let's install an e-mail client in order to send and receive e-mails. We will use Mozilla
Thunderbird here, but it can be replaced by any other e-mail client. Perform the following
steps to set up Thunderbird:

12. Download and install Mozilla Thunderbird from: http://www.mozilla.org/en-
US/thunderbird/.

13. Start Thunderbird by double-clicking on the icon installed on the desktop.

14. On the main window click Create a new account.


15. Enter Test User into the Your name field.

16. Enter testuser@localhost into the Email address field. Ignore the
warning message.

17. Enter testuser into the Password field.



18. Repeat step 14-17 for the OSB Admin  user.

19. Click Continue.

21. Test the two e-mail accounts by sending an e-mail message from the OSB Admin
account to the Test User account (E-mail address: testuser@localhost).


We have now configured the e-mail server and an e-mail client. Let's now implement the proxy
service which consumes e-mail messages from the testuser@localhost mailbox.

OSB-12C : XA Transactional Support feature

-
Image
OSB 12c supports both XA as well as Non-XA transactions. An XA transaction is a "global transaction" that may span multiple resources. It involves a coordinating transaction manager, with one or more databases (or other resources, like JMS) all involved in a single global transaction. XA transactions come from the X/Open group specification on distributed, global transactions. JTA includes the X/Open XA spec, in modified form. XA gets involved when you want to work with multiple resources - 2 or more databases, a database and a JMS connection, all of those plus maybe a JCA resource - all in a single transaction. In this scenario, you'll have an app server like WebSphere or Weblogic or JBoss acting as the Transaction Manager, and your various resources (Oracle, Sybase, IBM MQ JMS, SAP etc) acting as transaction resources.  Your code can then update/delete/publish/whatever across the many resources. When you say "commit", the results are committe...

Static code analysis of Terraform .tf files using ‘Checkov’ — Secure your infrastructure

-

  Hands on shelf! We can all agree that Terraform is great tool for infrastructure creation and provisioning. When we write terraform .tf files for infra creation we might miss something and we add something which can lead to security issues. Security should be prime factor for any devops related use-case. When I was searching internet for is there any tool which will scan terraform files and give a picture what may go wrong (from security perspective), I came across this very useful tool named ‘Checkov’ Link :  https://www.checkov.io/1.Welcome/Quick%20Start.html Checkov is a   static code analysis tool for scanning infrastructure as code (IaC) files for misconfigurations that may lead to security or compliance problems. Checkov includes more than 750 predefined policies to check for common misconfiguration issues. In this post, I am going to discuss how to do static code analysis of terraform tf files using checkov. step 1 : Install checkov in your machine. $ pip install...

OSB12c : Schema Validation - Dynamic Validation

-
Image
We can use validate node in OSB to validate schema. There was an option to validate the payload in OSB 11g but it was static, however from 12c there is a new feature included in the OSB validation activity that is validating the data dynamically. This will allow the user to validate the input data or other data dynamically based on certain condition. Thus the process can be stopped at the beginning itself the data validation goes wrong. You have the option to save the validation result or raise an error. Use case: 1. Create a WSDL based service 2. Add validate (dynamic) to validate incoming request structure. 3. If any violation in request structure compared with schema, Error will be raised with proper error code and description. Create new folder and name it as ‘DynamicValidateSchema_UseCase’. Create sub folders structure as shown in below image. For this use case we have created two XSDs and placed it inside Resources -> XSD folder EmployeeDetailsReq...
