Macro resource definition

Reference information for resource definition macros used to create CICS® tables.

Introduction to CICS control tables and macros
You can define most CICS resources by using resource definition online (RDO), but for some resources you must use CICS macros.
Defining resources in CICS control tables
Some CICS resource are defined in CICS control tables.
CLT—command list table
The command list table (CLT) is used by the extended recovery facility (XRF) and contains a list of MVS™ system commands and messages to the operator, to be issued during takeover. Typically, the function of these commands is to tell alternate systems to take over from their active systems in the same MRO-connected configuration.
PDIR—DL/I directory
The PDIR is a directory of all the remote program specification blocks (PSBs) that are accessed by the CICS system.
FCT—file control table
The file control table (FCT) describes to CICS the Basic Direct Access Method (BDAM) user files that are processed by file management.
MCT - monitoring control table
The monitoring control table (MCT) defines the user data fields in CICS monitoring performance class records and describes how they are manipulated at event monitoring points (EMPs). It also controls which system-defined performance class data fields are recorded.
PLT—program list table
A program list 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.
RST—recoverable service table
Note on terminology: DBCTL refers to the CICS—IMS/ESA® DBCTL (database control) interface.
SRT—system recovery table
The system recovery table (SRT) contains a list of codes for abends that CICS intercepts. After it intercepts one, CICS attempts to remain operational by causing the offending task to abend.
TCT—terminal control table
Use the DFHTCT macro to define SNA logical units (LUs) that support logical device codes and sequential devices attached by BSAM.
TLT—terminal list table
A terminal list table (TLT) generated by the DFHTLT macro instruction allows terminal and operator identifications to be grouped logically.
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. Any unique temporary storage identifier generated dynamically in an application program that begins with the same characters as the generic names automatically acquires the same properties as the TST entries.
XLT—transaction list table
The transaction list table specifies transactions that can be initiated from terminals during system termination, and groups of transactions that you want to enable or disable together. Use a TRANSACTION resource in preference to XLT.
