Time Gathering Systems Secure Data Collection for IBM System i Server (It’s about time . . . to change the perspective) Secure Data Collection for IBM System i Server

TG Communications Architecture Standard TCP sockets service Scalable and recoverable Non-polling for performance Automated startup and operation User defined system management Notification on error User interface via data queues

Standard TCP Sockets Service The TG Server on the System i platform is a standard TCP/IP sockets server. It listens on a user-defined port for connections from a data collection device, processes the data, and returns information to the device. Multiple data collection devices can connect at the same time to the same port. For each device, multiple transactions can be processed. After the connection is complete the TG communications service is ready for the next transaction. The TG Server can listen on a specific IP address or can operate in a multi-homed fashion.

Scalable and Recoverable The TG communications server handles multiple, simultaneous transactions from devices. Each device session is processed independently of other sessions. You can define up to 99 pre-started sessions to further improve performance. In the event of a network or application failure the TG Server will automatically recover and restart communications. Error event notifications are sent via email and message to QSYSOPR.

Non-polling System i Performance Unlike serial device connectivity, the TG Server does no polling of devices. Each device transaction is a real-time event which is processed as needed. This event-driven model for data collection transactions reduces system and network utilization. When transactions are not being processed, no system resources are used.

Automated Startup and Operation The TG Communications Service starts automatically when you start the communications subsystem TGDATAQ. An auto-start job in the subsystem definition starts the TCP server. By starting the subsystem in the QSTRUP program you can automatically start device communications support when you start your system. TG Communications support runs without operator or other human intervention.

User Defined System Management The TG Communications environment runs in its own subsystem. You use standard iSeries applications to configure the execution priority, job logging level, and other operational characteristics of the application. There is no need to modify job descriptions, classes, job queues, or other system objects.

Notification on Error In the event of a network or application failure, the TG Communications Support will send error notification messages and automatically restart. The notification messages can be sent via: SMTP email SNMP network management QSYSOPR message queue User-defined message queue

User Interface via Data Queues For customers using TGS Solutions, transactions are sent to a user-defined data queue. TG for Infinium Users is a Module that delivers Master file integration. All transactions are processed by standard user RPG or Cobol applications. The TG Communications Server will automatically start your transaction processing program if desired.
