About CICS Resource Definitions

In the Enterprise Server for .NET environment, a resource configuration is maintained as an XML file.

The installation software includes a sample resource configuration file named ResourceDefinitions.config. The sample region ESDEMO uses this resource definition file. This is installed in %ProgramData%\Micro Focus\Enterprise Developer\4.0\SEE\config.

Enterprise Server for .NET definition files are in a different format from those used in native Enterprise Server. Studio Enterprise Edition includes utilities that migrate native Enterprise Server definition files to a format used by Enterprise Server for .NET.

You can deploy resource definition files:

• As a file on a network location accessible to the installation's regions.
• To the cross-region database.

Use the Resource Editor to configure resource definition files. The Resource Editor lets you add and delete items, copy and paste items, and re-name group items.

The CICS resource types within a resource definition file are :

• PCT - Program Control Table
  • Defines the 4 character transaction id and the program name associated with it.
• FCT - File Control Table
  • The file control table (FCT) describes user files to CICS
• TST - Temporary Storage Table
  • The temporary storage table (TST) is a list of generic names (or prefixes) used to identify sets of temporary storage queues.
• PPT - Processing Program Table
  • Defines the load module characteristics to CICS.

    Each load module is defined using the DFHPPT definition, which includes the name of the load module (the PROGRAM field), and the language in which the module has been written. Examples are PL/I, Assembler, or COBOL (the PGMLANG field).

• PLT - Program Load Table
  • A program Load table (PLT) specifies programs that you want to run during CICS startup and shutdown, and groups of programs that you want to enable and disable together.
• DCT - Destination Control Table
  • The destination control table (DCT) contains an entry for each remote, extrapartition, intrapartition, and indirect destination.
• TCT - Terminal Control Table
  • CICS system can communicate with terminals, sequential devices, logical units, and other systems. The TCT defines each of the devices in the configuration. Each TCT entry defines the optional and variable features of the device to CICS, and specifies the optional and variable features of CICS to be used.
• TS Model
  • A TSMODEL specifies the properties of a set of TS queues. Individual TS queues are associated with a TSMODEL by the prefix, a character string that matches the leading characters of the queue name.
• Term
  • Defines the characteristics of a terminal device which communicates with CICS. Terminal devices include visual display units, printers
• TypeTerm

  • Defines a set of attributes that are common to a group of terminals.

    The resource is a logical extension of the TERMINAL resource. If you have a number of terminals with the same properties, you would define one TYPETERM with the required values, and then name that TYPETERM in each TERMINAL definition (or in the autoinstall model definition if you are using autoinstall)

• TRANCLASS

  • Defines the characteristics of a transaction class.

    Transactions that are defined as belonging to a transaction class are subject to scheduling constraints before they are allowed to execute. If transactions belonging to an active transaction class are already running, any new transactions are queued.

• SIT - System Initialization Table
  • Contains the initialization parameters used by the system when cold starting a CICS region.
