Oracle Solaris ZFS

Integrated Cloud, Applications and Platform Service

Oracle Solaris 11 delivers many path breaking innvovations in Operating System technology for you to build, deploy and manage many complex, mission critical, uninterruptable enterprise services.

Oracle Solaris ZFS offers dramatic advancement in data management, an innovative approach to data integrity, near-zero administration, and a welcome integration of file system and volume management capabilities. The centerpiece of the new architecture is the concept of a virtual storage pool, which decouples the file system from physical storage, allowing much more-efficient use of storage devices.


  1. Rock-solid data integrity: Data protected by 256-bit checksum, data consistency maintained at all times 
  2. No silent data corruption ever: ZFS self-healing feature automatically repairs corrupt data
  3. Mind-boggling scalability: 128-bit file system, zillion times the capacity of 32- or 64-bit file systems
  4. Breathtaking speed: Proven, cutting-edge technologies combined to optimize performance
  5. Near-zero administration: Complicated storage administration is automatic and simplified

My Presentation Oracle Solaris ZFS. Try it out. Simple and easy to follow steps.

Solaris DTrace, An Introduction

As a lead performance engineer with wide exposure to multiple applications in various industry domains, and working on Solaris10 platform for years. I believe, SolarisTM DTrace is one of the coolest innovations that could have ever happened in the Operating System world. DTrace was designed and implemented at Sun Microsystems by Bryan Cantrill, Adam Leventhal and Mike Shapiro.

DTrace is a comprehensive dynamic tracing framework created for troubleshooting kernel and application problems on production systems in real time. DTrace was developed for Solaris and released under the Common Development and Distribution License (CDDL). Other OS communities, after realizing the high potential and worthiness, have initiated projects to make DTrace available on respective operating systems.

DTrace can be used to get a global overview of a running system, such as the amount of memory, CPU time, filesystem and network resources used by the active processes. It can also provide much more fine-grained information, such as a log of the arguments with which a specific function is being called, or a list of the processes accessing a specific file. DTrace is Programmable, Flexible, Robust, Safe and Easy-to-Learn-and-Use. Possibilities are Endless !

    GlassFish V2 Clustering and Load Balancing - Simplified

    GlassFish V2 Enterprise Server was the first fully compliant Java EE 5 Application Server. Sun Microsystems first announced the project GlassFish in JavaOne 2005, an initiative to open source the Java EE Reference Implementation. First release was in JavaOne 2006.

    The key challenges among Enterprises or Next Generation web delivery companies is the growing user subscription base, requirement for scalability, high availability, a robust backbone, and most critically the cost-effectiveness. Deploy GlassFish with SPARC servers to provide a robust infrastructure solution with advanced features and capabilities.

    Presentation : GlassFish-V2-Clustering-Simplified.pdf

    The presentation is a sincere effort to simplify the understanding of GlassFish V2 Clustering and Load Balancing concepts, architecture, implementation and deployment configurations. The technical content has been tested for accuracy and reliability on multiple platforms. The presentation provides both the perspectives, technical and business advantages in adopting GlassFish technology.

    NetBeans 6.1, The Only IDE You Need!

    If you are ever wondering what is NetBeans, its really the confluence of world's best 'Three'

    1. A very popular IDE (Integrated Development Environment), which is open source
    2. One of the richest Platform, comprised of enormous set of Module and Plugins
    3. A large Thriving Community of Subscribers, and growing by the day

    NetBeans 6.1 IDE is completely developed on Java technology known for its portability and interoperability. NetBeans 6.1 is the "The Only IDE You Need!" to develop applications in almost any programming language. It's available on OS platform of your choice, Oracle Solaris, Microsoft Windows, Linux, Mac OS Intel. Build and manage entire Software Development Lifecycle (SDLC) within the single, most popular NetBeans 6.1 IDE.

    History of NetBeans goes back to the year 1996, developed as an academic project by the students of Prague University. Sun Microsystems sponsored the project in year 2000. Rich NetBeans Platform was born in 2001. The Platform comprises of extensive Packages and APIs, extendedable to rapidly build Rich Client applications. In 2006 NetBeans 5.0 was launched with comprehensive Module development support. NetBeans 6.x witnessed enhancements in Platform development e.g. Swing GUI builder (Matisse) among many other new features.

    My slide set 1). NetBeans 6.1 IDE (preso) and 2). NetBeans Platform (preso).

    Recommended by Geertjan WielengaNetBeans Platform Certified Engineering teaching resources, under Slides on Specialized Technical Topics and the Main NetBeans Platform APIs as "Excellent technical overview, covering the user interface support in NetBeans IDE, as well as the main NetBeans APIs."
