Vista Securities Processing System Modernization Guide

Vista Securities Processing System is a CICS-based system designed for securities and custodian processing. It handles trade capture, clearance, settlement, and accounting for various security types.

The system manages securities transactions from initiation to settlement, including trade order management, position keeping, and regulatory reporting.

Vista Securities Processing System was initially developed for mainframe environments using CICS. It leverages VSAM files and DB2 for data storage.

The system supports various security types, including equities, fixed income, and derivatives. It also handles corporate actions processing and dividend payments.

Common operations include trade entry using transaction codes like 'TREN', position inquiries via 'POSQ', and settlement processing with 'SETL'. Configuration files define security types and market parameters.

Vista Securities Processing System exposes COBOL copybooks for integration. Communication relies on SNA protocols.

The system comprises components like the Trade Processing Module, Settlement Engine, and Accounting Interface. These communicate through CICS inter-region communication (IRC).

Administrative interfaces are accessed through CICS panels. User management is handled via CICS security. Monitoring relies on CICS transaction monitoring facilities (TDQ and TSQ).

Vista Securities Processing System automates securities processing, reducing manual effort and improving operational efficiency. It provides real-time position keeping and supports regulatory compliance.

The system supports multiple security types and markets, enabling firms to manage diverse investment portfolios. It integrates with existing banking systems via COBOL copybooks.

By automating trade processing and settlement, Vista Securities Processing System reduces the risk of errors and delays. It provides audit trails for compliance purposes.

Vista Securities Processing System relies on CICS security for authentication. Access control is managed through CICS resource definition online (RDO).

Data at rest is secured using VSAM record-level security. Data in transit is protected using SNA LU6.2 encryption.

The system provides audit trails for all transactions and security-related events. Audit logs are stored in VSAM files.

Vista Securities Processing System is administered through CICS panels. Configuration parameters are stored in VSAM files.

Monitoring is performed using CICS transaction monitoring facilities (TDQ and TSQ). Performance metrics are collected via CICS performance analyzer.

Backup and recovery procedures involve standard CICS and VSAM utilities. Disaster recovery planning includes replicating CICS regions and VSAM files to a secondary site.
