Abstract:
CICS/VS is one element of online system organization that is called "Software Support". It helps creating a data base / data communication system which the user can tailor to suit the requirements of his particular application. A CICS/VS system consists of control modules, system tables, control areas, application programs and data sets. There is journal management in control modules that can be used to create data for checking CICS/VS operation. The data is stored chronologically into system journal data set. To create this data set, it consists of a CICS/VS Generation. It contains the creation of control modules and system tables that are related to this data set. b. Before CICS./VS execution. It contains the preparation extents of disk for this data set. c. CICS/VS execution. It contains the assignment of job control statements relating to this data set in startup job stream. When initializing CICS/VS system with prepared startup job stream and normally executing under the control of CICS/VS, journal management will automatically create and write data for checking CICS/VS operation to system journal data set. This data set is specified as the format of variable - length blacked record. It is necessary to read system journal data set, whenever an extant of disk journal is full and begins to reuse for output or CICS/VS system is shutdown. To read this data set, we use the program that is developed in this thesis.
