The sections above described the initial installation and configuration process. Once completed Connect CDC SQData is operationally ready to become active. IMS data that is changed will be logged by IMS, then Captured. Subscribing Engines will be authenticated by the Controller Daemon and CDC data will be Published via TCP/IP to each subscribing Engine, which will apply the data to the target datastores.
This section covers a few of the common operational activities likely to be encountered while in operation.
There are three methods supported for interacting with Connect CDC SQData components on z/OS:
1.ISPF panel Interface - The IMS Quickstart Guide provides detailed step by step instructions.
2.z/OS JCL - Traditional z/OS Jobs that execute the SQDCONF and SQDMON utilities and their full range of options for managing and controlling the SQDAEMON Controller Daemon and the z/OS IMS Log Reader Capture and zLog Publisher.
3.z/OS Console Commands - Duplicate many of the commands associated with the SQDCONF and SQDMON utility programs. Note, in order to issue any z/OS commands from TSO (including SDSF) the user must have TSO CONSOLE authority and possibly SDSF command authority.
