This IBM® Redbooks® publication shows the power of IBM System z® virtualization and flexibility in sharing resources in a flexible production environment. In this book, we outline the planning and setup of Linux on System z to move from a development or test environment into production. As an example, we use one logical partition (LPAR) with shared CPUs with memory for a production environment and another LPAR that shares some CPUs, but also has a dedicated one for production. Running in IBM z/VM® mode allows for virtualization of servers and based on z/VM shares, can prioritize and control their resources. The size of the LPAR or z/VM resources depends on the workload and the applications that run that workload. We examine a typical web server environment, Java applications, and describe it by using a database management system, such as IBM DB2®. Network decisions are examined with regards to VSWITCH, shared Open Systems Adapter (OSA), IBM HiperSockets™ and the HiperPAV, or FCP/SCSI attachment used with a storage area network (SAN) Volume Controller along with performance and throughput expectations. The intended audience for this IBM Redbooks publication is IT architects who are responsible for planning production environments and IT specialists who are responsible for implementation of production environments.

IBM® z/VM® 6.2 introduced significant changes to z/VM with a multi-system clustering technology that allows up to four z/VM instances in a single system image (SSI) cluster. This technology is important because it offers you an attractive alternative to vertical growth by adding new z/VM systems. In the past, this capability required duplicate efforts to install, maintain, and manage each system. With SSI, these duplicate efforts are reduced or eliminated. Support for live guest relocation (LGR) allows you to move Linux virtual servers without disrupting your business or incurring loss of service, thus reducing planned outages. The z/VM systems are aware of each other and take advantage of their combined resources. LGR enables you to relocate guests from a system requiring maintenance to a system that will remain active during maintenance. A major advantage for DB2 v10 customers is that using z/VM 6.2 does not require any changes to existing DB2 structures. This remarkable benefit is due to the fact that DB2 v10 is installed as part of the LInux guest on z/VM and is fully integrated into LGR. This allows you to smoothly move DB2 v10 when you move Linux virtual servers, without interrupting either DB2 v10 or z/VM operations and services. This IBM Redbooks® publication will help you understand how DB2 10 on Linux for System z® behaves while running on a z/VM that is being relocated using z/VM’s 6.2 Live Guest Relocation feature. In this book, we explore memory management, the DB2 Self-tuning memory manager feature, time synchronization, networking, and storage and performance considerations with regards to relocation. We also offer some best practices found during a live guest relocation for DB2 v10.

Beginning with IBM® CICS® Version 2, applications can run on TCBs apart from the QR TCB, which has positive implications for improving system throughput and for implementing new technologies inside of CICS. Examples of implementing new technologies include using the IBM MVS™ Java virtual machine (JVM) inside CICS and enabling listener tasks written for other platforms to be imported to run under CICS. The newest release, CICS Transaction Server for z/OS® (CICS TS) V4.2, includes scalability enhancements so that you can perform more work more quickly in a single CICS system. The advantage of this enhancement is that you can increase vertical scaling and decrease the need to scale horizontally, reducing the number of regions that are required to run the production business applications. The scalability enhancements in CICS TS V4.2 fall into two broad areas, which are increased usage of open transaction environment (OTE) and of 64-bit storage. This IBM Redbooks® publication is a comprehensive guide to threadsafe concepts and implementation for IBM CICS. This book explains how systems programmers, applications developers, and architects can implement threadsafe applications in an environment. It describes the real-world experiences of users, and our own experiences, of migrating applications to be threadsafe. This book also highlights the two most critical aspects of threadsafe applications: system performance and integrity.

This IBM® Redbooks® publication provides a basic introduction to the IBM System Storage® N series, virtualization, and VMware.

This IBM Redbooks publication discusses running Linux under z/VM on IBM System z9 and zSeries platforms. We describe enhancements available in z/VM Version 5.1. The intended audience for this book is IT administrators responsible for installing and configuring z/VM 5.1 systems running Linux guests. Using Fibre Channel Protocol (FCP), z/VM 5/1 can be installed on and operate from SCSI disks. Configured as emulated Fixed Block Architecture (FBA) disks, z/VM 5.1 can use FCP-attached disks for its system paging, spooling, directory, and minidisks. z/VM 5.1 adds new functions for Virtual Switches (VSWITCH). For increased network security, guests must have authorization before connecting to a VSWITCH. z/VM 5.1 introduces VSWITCH Layer 2 support. Operating at Layer 2, a VSWITCH delivers and receives network traffic in Ethernet frames. This provides the ability to handle non-IP protocols such as SNA, NetBIOS, and IPX. In addition, Layer 2 support reduces network latency and CPU overhead.
