• Immutability and appendOnly features in GPFS 3.4v on AIX

  Protect your business data on IBM AIX® systems using immutability and appendOnly features supported by IBM® General Parallel File System (IBM GPFS™) V3.4 ensuring compliance to various government regulations. Having rich set of command line interfaces, GPFS allows you to set appropriate restrictions to your business audit files, health center records and log files in order to effectively secure them from being tampered with or accidentally deleted. This article illustrates how to make use of immutability and appendOnly restrictions offered by IBM GPFS V3.4 to protect your AIX data.

• SWIG for developers in a hurry

  SWIG is a nifty open source tool that lets you integrate C/C++ code with just about any mainstream scripting language. Among other things, it exposes the code base to a wider audience, improves testability, and lets a portion of your Ruby code base run off high-performance C/C++modules.

• Troubleshooting and performance analysis of different applications in Versioned WPARs

  Versioned Workload Partitions (WPARs) is a new revolution in the area of WPARs in the IBM AIX® operating system. Applications that are supported in existing operating systems can also be configured to run in Versioned WPARs. However, there can be issues while configuring and running the same applications in Versioned WPARs. This article addresses trouble shooting of problems that might occur when common applications such as IBM WebSphere® Application Server, IBM DB2® and others are started in Versioned WPARs. This article also discusses the performance comparison of applications and benefits of moving an existing setup(on older hardware) to new IBM POWER7® hardware in the form of Versioned WPARs.

• Migration of WebSphere Deployment from IBM WebSphere Application Server Network Deployment V6 to V7 on AIX 6.1

  This article provides insight to a migration exercise in clustered production environment and covers issues and resolutions on the way to successfully achieving the migration of complex network deployment configuration from IBM WebSphere® Application Server Network Deployment (ND) V6 to V7 on AIX® 6.1 platform. The WebSphere and AIX system administrators would benefit most from this article as these migration issues may occur in one form or the other.

• Introduction to text manipulation on UNIX-based systems

  This introduction to text manipulation on UNIX platforms provides an overview of some common commands widely available and installed standard on most UNIX-based releases. Many times these standard utilities are ignored in favor of more modern text-processors such as Perl, Python, or Ruby, which are not always installed on a system. An introductory review of these tools helps practitioners who are learning UNIX or Linux or those who may be looking to renew forgotten knowledge.

• The performance detective: Where does it hurt?

  Learn how describing performance problems on an AIX system can help you diagnose and fix them. Pinpoint the real issues with your system, and discover how the key to understanding why a system is responding poorly is knowing where to look and what questions to ask.

• Hardware migration using alt_disk_copy

  Examine how to use the alt_disk_copy utility to migrate your rootvg disks to new hardware, and learn how this method is practicable when you do not have the facility or resource of using remote network installs.

• VIOS disk mapping in a nutshell

  Examine a simple way to map disk devices within VIOS servers, without caring about name patterns. Although name patterns are important, learn how to bypass them if necessary when troubleshooting servers.
