The Virtual CICS user group is an independently-operated vendor-neutral site run by and for the CICS user community.
The Virtual CICS user group was established as a way for individuals using IBM's CICS TS systems to exchange information, learn new techniques, and advance their skills with the product.
This Web site provides a central point for coordinating periodic meetings (which contain technically-oriented topics presented in a webinar format), and provides articles, discussions, links, and other resources of interest to IBM CICS practitioners. Anyone with an interest in CICS is welcome to join the Virtual CICS user group and share in the knowledge exchange.
CICS recovery provides the fundamental support for successful transaction processing. This presentation will discuss the concepts of recovery, and how they are applied within a CICS environment. It will talk about the relationships between transactions, units of work, logstream data and syncpoint processing. The various types of CICS restart will be considered, along with the actions CICS has to complete for both dynamic transaction backout and emergency restarts. We will discuss the different ideas within commit processing, and see how CICS manages its log data written to the z/OS Logger.
