Continuous data collection (CDC) is an application that collects real-time TPF 4.1 system performance information. CDC uniquely stores the data in a table in a remote relational database by using the TPF Application Requester (TPFAR) feature. An offline application is then used to interpret and display the data. The name of the table is SYSTPF.TPF_DATA. This information is available in the database on a continual basis, so you can use CDC as a monitoring tool. You can run CDC with a minimum impact on TPF 4.1 system performance. Data collected in CDC is a subset of the data collected by the system performance and measurement package.
You can use the CDCA and CDCB user exits to assist in recording additional data. See TPF System Installation Support Reference for more information on the CDCA and CDCB user exits.
You can use the ZCDCO command to manage CDC. See TPF Operations for more information on the ZCDCO command.
