DC/UCF System Generation › Online Components and System Tasks

Online Components and System Tasks

A DC/UCF system can include CA IDMS online components and system tasks. Some online components are supplied with DC and UCF; others must be purchased as separate products. System tasks are supplied with DC and UCF.

Online Components

CA supplies the following online components for a DC/UCF system:

• CA ADS—A fourth-generation application development environment used to create and execute online applications that access and update CA IDMS databases
• Automatic System Facility (ASF)—A facility to create and update non-sql defined data tables
• IDD menu facility—A menu-driven facility to use the IDD Data Dictionary Definition Language (DDDL) compiler
• CA IDMS Performance Monitor—CA IDMS Performance Monitor A product to report on DC/UCF task activity
• CA ICMS—CA ICMS A product to link personal computers to the data management and storage capabilities of the mainframe computer
• Online debugger—A facility to detect, trace, and eliminate errors in programs running under the control of DC or UCF
• CA IDMS Online Command Facility (OCF)—CA IDMS Online Command Facility A facility used to create and maintain CA IDMS physical database definitions and SQL-defined databases
• Online IDD—An online version of the IDD DDDL compiler
• CA IDMS Mapping Facility—An online version of the facility used to define maps for communication between applications and terminal operators
• CA OLQ—A product to retrieve and format information from CA IDMS databases through an English-like query language or SQL
• Online schema compiler—An online version of the compiler used to create and update non-SQL defined schemas
• Online subschema compiler—An online version of the compiler used to create and update subschemas
• Online system generation compiler—An online version of the compiler used to define DC/UCF systems
• Transfer control facility (TCF)—A facility to control multiple sessions of one or more CA IDMS online development tools for a single user

System Tasks

CA-supplied system tasks are:

• BYE or B signs the user off from the DC/UCF system and terminates the connection with the system.
• CLIST executes a series of task statements that are in a module and stored in the data dictionary.
• CLOD erases logically deleted modules from the load area (DDLDCLOD) of the data dictionary.
• DCMT allows DC/UCF users to monitor system runtime activities and to update system definitions while a DC/UCF system is executing.
• DCPROFIL allows DC/UCF users to display information about the configuration of a DC/UCF system.
• DCUF provides user functions that control various aspects of a DC/UCF terminal session.
• LOCKMON allows DC/UCF users to display information about the lock status in their DC/UCF system.
• LOOK allows DC/UCF users to view the contents of selected load modules.
• OLP (online PLOG) allows DC/UCF users to display the current contents of the DDLDCLOG area online.
• OPER enables DC/UCF users to monitor system activity and to cancel active task threads.
• QUED erases expired queues from the queue area (DDLDCRUN) of the data dictionary.
• SDEL erases logically deleted users from the database security area (SYSUSER.DDLSEC).
• SEND transmits a user-supplied message to other DC/UCF terminals.
• SHOWMAP displays maps defined using the CA IDMS Mapping Facility.
• SIGNOFF signs the user off from the DC/UCF system but maintains the connection with the system.
• SIGNON or S signs the user on to the DC/UCF system.
• SUSPEND terminates UCF dedicated mode but maintains the connection with the UCF back end.

The SYSGEN members that must be included in the DC/UCF system definition for the CA IDMS online components and system tasks listed previously are presented in System Programs and Tasks.
