PBUSE PLUS


testing, sustainability, training and cus- tomer support operations—all from a single computing environment. Tus, the SuperCluster provides greater flex- ibility and support growth to the system administrator where needed; it can expand compute nodes, database storage or general-purpose storage independently of the other capabilities.


WORKING THE SYSTEM Personnel at SEC-Lee try to “break the system” during government acceptance interoperability testing for Interim Change Package 7.0.2 in September 2013. Eighteen testers participated, providing feedback and concurrence on the upcoming software release. The enterprise architecture upgrade provides increased performance, scalability and flexibility, while enhancing system security. (Photo by Mike Dunbar, SEC-Lee)


Tis hardware upgrade has signifi- cantly improved the responsiveness and availability of the PBUSE application, providing faster results and allowing the Soldier in the field to perform mission- critical tasks. Within the first 12 hours of the hardware cut-over, server activ- ity increased dramatically, using only 2 percent of the Web and application server capacity with more than 16,000 users logged into PBUSE; some 18 million database plus


actions and 45,000- transactions were posted to the


activity register. Te multipurpose


engineering system


has pre-integrated servers comprising T4 processors running Solaris 11; Exadata Storage Servers for increased database performance; low-latency, high-speed InfiniBand I/O fabric connecting all components; cloud management appli- cations; journaling file systems that are self-healing; and an external ZFS storage array that provides both high perfor- mance and the ability to preserve and manage large volumes of file-based data. Te Database Exadata storage is approxi- mately 100 terabytes (TB), and the ZFS file system storage is approximately 55 TB.


HARNESSING PBUSE SFC Eileen Espelien of the Training Support Unit at the Minnesota National Guard’s Camp Ripley Training Center performs a sub-hand receipt inventory using PBUSE. The decision to acquire the Oracle SuperCluster to replace the PBUSE server architecture was a response to severe server problems in accommodating an increasing PBUSE mission workload.
