Send e-mail with attachment through OSB

Oracle Service Bus (OSB) contains a good collection of adapter to integrate with any legacy application, including ftp, email, MQ, tuxedo. However e-mail still recognize as a stable protocol to integrate with any application asynchronously. Send e-mail with attachment is a common task of any business process. Inbound e-mail adapter which, integrated with OSB support attachment but outbound adapter doesn't. This post is all about sending attachment though JavaCallout action. There are two ways to handle attachment in OSB: 1) Use JavaCallout action to pass the binary data for further manipulation. It means write down a small java library which will get the attachment and send the e-mail. 2) Use integrated outbound e-mail adapter to send attachment, here you have to add a custom variable named attachment and assign the binary data to the body of the attachment variable. First option is very common and easy to implement through javax.mail api, however a much more developer manage t

Tip: SQL client for Apache Ignite cache

A new SQL client configuration described in  The Apache Ignite book . If it got you interested, check out the rest of the book for more helpful information. Apache Ignite provides SQL queries execution on the caches, SQL syntax is an ANSI-99 compliant. Therefore, you can execute SQL queries against any caches from any SQL client which supports JDBC thin client. This section is for those, who feels comfortable with SQL rather than execute a bunch of code to retrieve data from the cache. Apache Ignite out of the box shipped with JDBC driver that allows you to connect to Ignite caches and retrieve distributed data from the cache using standard SQL queries. Rest of the section of this chapter will describe how to connect SQL IDE (Integrated Development Environment) to Ignite cache and executes some SQL queries to play with the data. SQL IDE or SQL editor can simplify the development process and allow you to get productive much quicker. Most database vendors have their own front-en

8 things every developer should know about the Apache Ignite caching

Any technology, no matter how advanced it is, will not be able to solve your problems if you implement it improperly. Caching, precisely when it comes to the use of a distributed caching, can only accelerate your application with the proper use and configurations of it. From this point of view, Apache Ignite is no different, and there are a few steps to consider before using it in the production environment. In this article, we describe various technics that can help you to plan and adequately use of Apache Ignite as cutting-edge caching technology. Do proper capacity planning before using Ignite cluster. Do paperwork for understanding the size of the cache, number of CPUs or how many JVMs will be required. Let’s assume that you are using Hibernate as an ORM in 10 application servers and wish to use Ignite as an L2 cache. Calculate the total memory usages and the number of Ignite nodes you have to need for maintaining your SLA. An incorrect number of the Ignite nodes can become a b
