  10. The need for an integrated software development environment and application framework to  Support the development and operation of various real time distributed meteorological data processing systems.  Reduce the efforts in developing and maintaining similar automation mechanism for different application systems. (maximize reusability)  Integrate past experiences and best practices in system operation mechanism development become an unified architecture and tool kits for optimal system operations.  Utilizing open system software technologies, components & standards to speed up AP development while maintaining the system’s operability, flexibility, reliability and interoperability.

  12. NICE components (1/3) (1)Information Transport facility - IT Provides the solutions for reliably exchange of data and/or messages in different hosts within or among systems across network. Access controls can be applied to information objects and hosts if so wished. (2)Process Automation facility - PA Provides the solutions for automated processes management. The process activation mechanisms include : time driven (one time or periodical), event driven (single event or logical combination of multiple events). The management functions include : creation / deletion / rerun, process queueing, # of processes, execution elapse time, … (3)Data Access and Management facility - DA/DM Provides the solutions for on-line data records and files access in local or remote hosts across network. Files can be either plane or indexed. File management mechanism includes : creation, purging, archiving, backup, restore. CWB NICE - Mark Cheng 12 2011/4/1

  13. NICE components (2/3) (4)Information Service facility - IS Provides the solutions for reliably receiving and sending information objects with standard FTP, RCP & LDM protocols to interface the outside world. Status detection, Timeout, retry, multithreading and queueing mechanisms are provided for reliable transport management. (5)System MONitoring & LOGging facility – MON/LOG Provides the solutions for detecting, monitoring, logging & reporting resource utilization and/or processes activities events of application systems. Events include : resource usage & utilization, data availability, network connectivity, process life cycle, activities timing. All events can be centralized managed and displayed in an operator UI. (6)System Fail Over facility - FO Provides the solutions for maintaining high availability of system operation. Critical resources and services can be configured, monitored, managed and failovered by a decision making kernel with the support of activity monitoring, abnormal detection and fault isolation. CWB NICE - Mark Cheng 13 2011/4/1

  14. NICE components (3/3) (7)User Interfacing facility - UI Provides the solutions for users and operators to interface with the system. A set of X-window based widgets include : menu items, selection list, command button, file selection, text entry, dialog box & message window can be configured and composed via a scripting language for system’s specific needs. (8)MSS interfacing facility - MSS Provides the solutions for interfacing with the Hierarchical Storage Management system in CWB. Storage pool inventory query, migration/de- migration control and basic file operations can be applied to file objects in local and/or remote storage devices and/or servers. (9)HPC interfacing facility - HPC Provides the client side solution for interfacing with the High Performance Computer system in CWB. A Simplified commands set to encapsulate different batch systems commands for most commonly used commands for Job submission, execution control & status query. CWB NICE - Mark Cheng 14 2011/4/1
