  1. SAS software with Hortonworks Data Platform (HDP) running on IBM POWER8
    This article describes how to set up an environment where SAS can access and analyze data stored on Hortonworks Data Platform (HDP) using SAS/ACCESS Interface to Hadoop. The environment is running on IBM POWER8 processor-based servers.
  2. Updating the Olson time zone database on IBM AIX
    This article helps users to understand how to update the Olson time zone database on IBM AIX whenever it is periodically updated with the latest time zone changes.
  3. Building open source RPM packages on IBM AIX
    RPM is a very popular packaging method for installing and managing software. Different Linux distributions provide open source software in RPM format. Building and managing RPM packages on IBM AIX is similar to Linux distributions but with some changes. This article describes how to build an open source software RPM package on AIX.
  4. A simplified approach to hardware upgrade using IBM Geographically Dispersed Resiliency for Power Systems
    This article explains the advantages of using IBM Geographically Dispersed Resiliency for Power Systems for planned hardware upgrades followed by a detailed walk-through of the steps for performing the upgrade.
  5. IBM PowerHA/Cluster Aware AIX (CAA) tunables guide
    This article explains about IBM PowerHA and Cluster Aware AIX (CAA) tunables, their default values, and the recommended values for the PowerHA cluster environment.
  6. Bidirectional supports for disaster recovery using IBM Geographically Dispersed Resiliency for Power Systems
    This article demonstrates the working of bidirectional support for disaster recovery using the IBM Geographically Dispersed Resiliency for Power Systems solution, where two sites can handle the configuration in both directions.
  7. Preserving redundant VIOS configuration on production site with IBM Geographically Dispersed Resiliency solution
    IBM Geographically Dispersed Resiliency for Power Systems is an innovative disaster recovery (DR) solution to recover virtual machines (VMs). In enterprise customer environments, multipathing I/O with dual Virtual I/O Server (VIOS) configuration is widely employed for redundancy. This article suggests a procedure to perform disaster recovery to move the VMs that have dual VIOS setup on host at production or active site to a backup site with a single VIOS setup in the backup hosts. The article also explains the procedure to preserve the original dual VIOS configuration after the VMs move back to the previous site again.
  8. Implementing server-side caching of storage data in an IBM PowerHA cluster environment
    This article explains the implementation of server-side caching of storage data in an IBM PowerHA cluster environment. This can help in reducing average latency of the workloads and achieving better write throughput by offloading requests from a storage area network (SAN). This helps in effectively serving many clients and hosts.
  9. Developing applications using libusb in IBM AIX
    libusb is an open source library that allows you to develop user space drivers (applications) for USB devices. This article provides detailed steps on developing applications using libusb on IBM AIX. Users can write driver software on AIX for their USB devices to communicate with them. This article gives detailed description on installation and configuration of libusb on AIX, enumeration of libusb devices, and how to develop applications using libusb APIs.
  10. AHAFS events support for adding and removing USB devices in IBM AIX
    Hot plugging a device in a system means the device is discovered and configured by the system without reboot or without manual intervention. The existing USB infrastructure in IBM AIX does not support discovering devices on hotplug. A configuration manager command must be invoked manually to discover the new USB devices attached to the AIX system. This article explains the hotplug infrastructure provided for USB devices in AIX and how it can be used by the applications.
