The Java 8 Streams library makes it easy to run code in parallel. A common error is code that works when run sequentially but that misbehaves when run in parallel. This is often caused by programmers who are stuck in a mode of imperative, left-to-right thinking. This leads to an iterative style in which data is mutated and where the next result depends on the result of the previous computation, creating barriers to parallel computation. This presentation covers an alternative programming technique called array programming, where operations are applied on data aggregates instead of individual elements. It also includes examples and demonstrations that illustrate these techniques and how they lead to easier-to-understand, parallel-ready code.

DataStage jobs can be parameterized to allow for portability and flexibility. Parameters are used to pass values for variables into jobs at run time. There are two types of parameters supported by DataStage jobs: Standard job parameters --Are defined on a per job basis in the job properties dialog box. --The scope of a parameter is restricted to the job. --Used to vary values for stage properties, and arguments to before/after job routines at runtime. --No external dependencies, as all parameter metadata is a sub element to a single job. Environment variable parameters: --Use operating system environment variable concept. --Provide a mechanism for passing the value of an environment variable into a job as a job parameter (Environment variables defined as job parameters start with a $ sign). --Are similar to a standard job parameter in that it can be used to vary values for stage properties, and arguments to before/after job routines. --Provide a mechanism to set the value of an environment variable at runtime. DataStage provides a number of environment variables to enable / disable product features, fine-tune performance, and to specify runtime and design time functionality (for example, $APT_CONFIG_FILE).
