Download or read book Considerations for Transitioning Highly Available Applications to System z written by Alex Louwe Kooijmans and published by IBM Redbooks. This book was released on 2011-10-14 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: You may have several triggers to investigate the feasibility of moving a workload or set of workloads to the IBM® System z® platform. These triggers could be concerns about operational cost, manageability, or delivering the agreed service levels, among others. Investigating the feasibility of a possible migration or transition to any other platform, including System z, requires a number of basic steps. These steps usually start with an understanding of the current workload and its pain points, and end with a business case to move the workload. It is important to find out how easy a migration is going to be and how much risk will be involved. In this IBM Redbooks® publication we offer thoughts on how to move through these steps. We also include a chapter with a System z technology summary to help you understand how a migrated workload may fit on the platform. Our focus in this book is on workloads that are mission-critical and require a high level of availability, including disaster recovery.

Download or read book System z Mean Time to Recovery Best Practices written by Frank Kyne and published by IBM Redbooks. This book was released on 2010-03-22 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This IBM® Redbooks® publication provides advice and guidance for IBM z/OS® Version 1, Release 10 and subsystem system programmers. z/OS is an IBM flagship operating system for enterprise class applications, particularly those with high availability requirements. But, as with every operating system, z/OS requires planned IPLs from time to time. This book also provides you with easily accessible and usable information about ways to improve your mean time to recovery (MTTR) by helping you achieve the following objectives: - Minimize the application down time that might be associated with planned system outages. - Identify the most effective way to reduce MTTR for any time that you have a system IPL. - Identify factors that are under your control and that can make a worthwhile difference to the startup or shutdown time of your systems.

Download or read book Improving z OS Application Availability by Managing Planned Outages written by Frank Kyne and published by IBM Redbooks. This book was released on 2014-12-22 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This IBM® Redbooks® publication is intended to make System Programmers, Operators, and Availability Managers aware of the enhancements to recent releases of IBM z/OS® and its major subsystems in the area of planned outage avoidance. It is a follow-on to, rather than a replacement for, z/OS Planned Outage Avoidance Checklist, SG24-7328. Its primary objective is to bring together in one place information that is already available, but widely dispersed. It also presents a different perspective on planned outage avoidance. Most businesses care about application availability rather than the availability of a specific system. Also, a planned outage is not necessarily a bad thing, if it does not affect application availability. In fact, running for too long without an IPL or subsystem restart might have a negative impact on application availability because it impacts your ability to apply preventive service. Therefore, this book places more focus on decoupling the ability to make changes and updates to your system from IPLing or restarting your systems.

Download or read book System z Parallel Sysplex Best Practices written by Frank Kyne and published by IBM Redbooks. This book was released on 2011-01-11 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This IBM® Redbooks® publication pulls together diverse information regarding the best way to design, implement, and manage a Parallel Sysplex® to deliver the levels of performance and availability required by your organization. This book should be of interest to system programmers, availability managers, and database administrators who are interested in verifying that your systems conform to IBM best practices for a Parallel Sysplex environment. In addition to z/OS® and the sysplex hardware configuration, this book also covers the major IBM subsystems: CICS® DB2® IMSTM MQ WebSphere® Application Server To get the best value from this book, readers should have hands-on experience with Parallel Sysplex and have working knowledge of how your systems are set up and why they were set up in that manner.

Download or read book Threadsafe Considerations for CICS written by Chris Rayns and published by IBM Redbooks. This book was released on 2012-04-05 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 MVSTM 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.

Download or read book DS8870 Data Migration Techniques written by Bertrand Dufrasne and published by IBM Redbooks. This book was released on 2017-11-16 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This IBM® Redbooks® publication describes data migrations between IBM DS8000® storage systems, where in most cases one or more older DS8000 models are being replaced by the newer DS8870 model. Most of the migration methods are based on the DS8000 Copy Services. The book includes considerations for solutions such as IBM Tivoli® Productivity Center for Replication and the IBM Geographically Dispersed Parallel SysplexTM (GDPS®) used in IBM z/OS® environments. Both offerings are primarily designed to enable a disaster recovery using DS8000 Copy Services. In most data migration cases, Tivoli Productivity Center for Replication or GDPS will not directly provide functions for the data migration itself. However, this book explains how to bring the new migrated environment back into the control of GDPS or Tivoli Productivity Center for Replication. In addition to the Copy Services based migrations, the book also covers host-based mirroring techniques, using IBM Transparent Data Migration Facility (TDMF®) for z/OS and the z/OS Dataset Mobility Facility (zDMF).
