zDataConnect Modernization Guide

zDataConnect enables applications on one z/OS system to access sequential datasets residing on another z/OS system without requiring modifications to the application code. It intercepts I/O requests and redirects them to the target system.

zDataConnect uses standard z/OS communication protocols, such as TCP/IP, to establish connections between systems. It leverages existing network infrastructure for data transfer.

No, zDataConnect is designed to be transparent to applications. It intercepts dataset access requests at the system level, eliminating the need for application code changes.

zDataConnect supports various sequential dataset organizations, including physical sequential (PS), partitioned datasets (PDS), and extended sequential datasets (ESDS).

The core components include the Intercept Module, which intercepts I/O requests; the Communication Manager, which handles network communication; and the Security Manager, which enforces access control policies.

zDataConnect uses configuration files, typically in PARMLIB datasets, to define dataset mappings, communication parameters, and security policies. These files are read during system initialization.

zDataConnect uses standard z/OS security mechanisms, such as RACF, ACF2, or Top Secret, for authentication and authorization. It integrates with these security systems to enforce access control policies.

zDataConnect provides a CLI for administrative tasks, such as configuring dataset mappings, managing security policies, and monitoring system activity. The CLI is accessed through a TSO session or a z/OS console.

zDataConnect logs system activity, including dataset access requests, security events, and error messages, to SMF records and system logs. These logs can be used for auditing and troubleshooting.

zDataConnect reduces the need for data replication and transfer, minimizing storage costs and network bandwidth usage. It enables real-time access to data, improving decision-making and operational efficiency.

By providing transparent access to remote datasets, zDataConnect eliminates the need for complex data integration processes. This simplifies application development and reduces maintenance costs.

zDataConnect enables organizations to consolidate data storage and management, reducing infrastructure complexity and improving resource utilization. This leads to cost savings and increased agility.

zDataConnect supports authentication methods such as LDAP, Kerberos, and multi-factor authentication (MFA) to verify user identities. It integrates with existing security infrastructure for seamless authentication.

zDataConnect uses an access control model based on Role-Based Access Control (RBAC). Administrators assign roles to users, and these roles determine the datasets and operations that users are authorized to access.

zDataConnect uses encryption protocols such as TLS/SSL to protect data in transit between systems. It also supports encryption at rest for sensitive datasets, using z/OS encryption facilities.

zDataConnect provides comprehensive audit logging capabilities, recording all dataset access requests, security events, and administrative actions. These logs can be used for security monitoring and compliance reporting.

zDataConnect can be monitored using standard z/OS monitoring tools, such as SMF and RMF. It also provides a dedicated monitoring interface that displays system status, performance metrics, and error messages.

zDataConnect supports automated restart and recovery procedures to ensure high availability. It can be integrated with z/OS workload management systems to prioritize critical dataset access requests.

zDataConnect can be integrated with z/OS automation tools, such as IBM System Automation for z/OS, to automate routine administrative tasks and respond to system events. This reduces operational overhead and improves efficiency.
