Book Description
Jobs and spooled output consume system resources, mainly the CPU used to create and manage them and the storage to contain them. Typically, in most environments, you can manage resources that jobs and spooled files consume successfully. However, on the largest systems, with the largest numbers of jobs and very large numbers of spooled files, you can encounter limits. Too many jobs can fill up the job table, or too many spooled files can consume all the system's storage. Having a large number of jobs and spooled files in the system can contribute to potentially long IPLs for unexpected outages. Having a very large number of spooled files on a single output queue can result in lock contention. This IBM® Redpaper publication describes best practices and recommendations for managing jobs and spooled output on IBM i. It provides an overview of the various controls within the IBM i operating system that you can configure to adjust the limits for spooled output and jobs. It also provides recommendations for setting these values. We do not explain in detail each of the configuration controls that we discuss in this paper. Rather, if you need additional information regarding the topics that we discuss, see the IBM i 6.1 Information Center at: http://publib.boulder.ibm.com/iseries/

Book Description
Monitoring and managing your system's performance is critical to ensure that you are keeping pace with the changing demands of your business. To respond to business changes effectively, your system must change too. Managing your system, at first glance, might seem like just another time-consuming job. But the investment soon pays off because the system runs more efficiently, and this is reflected in your business. It is efficient because changes are planned and managed. Managing performance of any system can be a complex task that requires a thorough understanding of that system's hardware and software. IBM® i is an industry leader in the area of performance management and has many qualities that are not found in other systems, such as: - Unparalleled performance metrics - Always-on collection of metrics - Graphical investigation of performance data While understanding all the different processes that affect system performance can be challenging and resolving performance problems requires the effective use of a large suite of tools, the functions offered by IBM i are intended to make this job easier for users. This IBM Redbooks® publication explains the tasks and rich tools associated with performance management on IBM i.

Book Description
In this IBM® Redbooks® publication, we present guidelines for the development of highly efficient and scalable information integration applications with InfoSphereTM DataStage® (DS) parallel jobs. InfoSphere DataStage is at the core of IBM Information Server, providing components that yield a high degree of freedom. For any particular problem there might be multiple solutions, which tend to be influenced by personal preferences, background, and previous experience. All too often, those solutions yield less than optimal, and non-scalable, implementations. This book includes a comprehensive detailed description of the components available, and descriptions on how to use them to obtain scalable and efficient solutions, for both batch and real-time scenarios. The advice provided in this document is the result of the combined proven experience from a number of expert practitioners in the field of high performance information integration, evolved over several years. This book is intended for IT architects, Information Management specialists, and Information Integration specialists responsible for delivering cost-effective IBM InfoSphere DataStage performance on all platforms.

Book Description
The IBM® i operation system (formerly IBM i5/OS®) is considered one of the most secure systems in the industry. From the beginning, security was designed as an integral part of the system. The System i® platform provides a rich set of security features and services that pertain to the goals of authentication, authorization, integrity, confidentiality, and auditing. However, if an IBM Client does not know that a service, such as a virtual private network (VPN) or hardware cryptographic support, exists on the system, it will not use it. In addition, there are more and more security auditors and consultants who are in charge of implementing corporate security policies in an organization. In many cases, they are not familiar with the IBM i operating system, but must understand the security services that are available. This IBM Redbooks® publication guides you through the broad range of native security features that are available within IBM i Version and release level 6.1. This book is intended for security auditors and consultants, IBM System Specialists, Business Partners, and clients to help you answer first-level questions concerning the security features that are available under IBM. The focus in this publication is the integration of IBM 6.1 enhancements into the range of security facilities available within IBM i up through Version release level 6.1. IBM i 6.1 security enhancements include: - Extended IBM i password rules and closer affinity between normal user IBM i operating system user profiles and IBM service tools user profiles - Encrypted disk data within a user Auxiliary Storage Pool (ASP) - Tape data save and restore encryption under control of the Backup Recovery and Media Services for i5/OS (BRMS) product, 5761-BR1 - Networking security enhancements including additional control of Secure Sockets Layer (SSL) encryption rules and greatly expanded IP intrusion detection protection and actions. DB2® for i5/OS built-in column encryption expanded to include support of the Advanced Encryption Standard (AES) encryption algorithm to the already available Rivest Cipher 2 (RC2) and Triple DES (Data Encryption Standard) (TDES) encryption algorithms. The IBM i V5R4 level IBM Redbooks publication IBM System i Security Guide for IBM i5/OS Version 5 Release 4, SG24-6668, remains available.
