Mainframe - OPC

  1. 1. Mainframe - OPC www.srinimf.com
  2. 2. What is OPC? • Tivoli Operations Planning and Control, version 2 Release 3 (OPC), and • Tivoli Workload Scheduler, Version 7 Release 0 (TWS).
  3. 3. Usage of OPC • A customer can fill out an order form on their Web browser that will trigger a UNIX job that acknowledges the order, an AS/400 job that orders parts, an OS/390 job that debits the customer’s bank account, and a Windows NT job that prints a document and address labels. • End-to-End Scheduling with OPC and TWS Mainframe and Distributed Environments • The solution is to use OPC and TWS working together across the enterprise. The Job Scheduling Console provides a centralized control point with a single interface to the workload regardless of whether that workload is running under OPC or TWS.
  4. 4. OPC Architecture • OPC consists of a Controller and one or more trackers. The Controller runs on an OS/390 system. The Controller manages the OPC databases and the long term and current plans. • The Controller schedules work and causes jobs to be submitted to the appropriate system at the appropriate time. • Trackers are installed on every system managed by the Controller. The tracker is the link between the Controller and the managed system. The tracker submits jobs when the Controller instructs it to do so, and it passes job start and job end information back to the Controller.
  5. 5. Contd… • Trackers are available for OS/390, OS/400, AIX/6000, OS/2, Sun Solaris, SunOS, Digital OpenVMS, Windows NT, SGI IRIX, HP-UX,and OS/390 USS. It is possible to schedule and track jobs on applications, such as SAP R/3. • The main method of accessing the Controller is via ISPF panels, but several other methods are available including Program Interfaces, TSO commands, and a GUI interface
  6. 6. TWS Architecture • TWS consists of a Master Domain Manager that contains the centralized database files used to document scheduling objects. It creates the production plan at the start of each day and performs all logging and reporting for the network. • All communications to agents are routed through the Domain Manager, which is the management hub in a domain.
  7. 7. Contd… • The network can be managed by a mix of agents. Fault- tolerant agents are capable of resolving local dependencies and launching their jobs should a network interruption cause a loss of communication with their Domain Managers because each one is given a set of scheduling instructions at the beginning of every processing day. • Version 7.0 introduced a new Java GUI, the Job Scheduling Console (JSC). • The JSC provides a common interface to both TWS and OPC
