Product Overview

IBM Z JCL Expert is built on a modular architecture consisting of several key components: * **JCL Parser:** Analyzes JCL syntax and extracts relevant information. * **Rule Engine:** Applies validation rules based on configuration files. * **Dataset Checker:** Verifies the existence and accessibility of datasets.

* **Db2 Plan Validator:** Validates Db2 plans referenced in the JCL. * **Security Policy Enforcer:** Enforces security policies and access controls. * **Reporting Engine:** Generates validation reports and audit trails.

These components communicate through internal APIs and message queues. The tool uses configuration files, typically in XML or YAML format, to define validation rules, dataset naming conventions, and security policies. It supports authentication methods such as LDAP, RACF, and Kerberos, and uses Role-Based Access Control (RBAC) to manage user permissions.

The tool exposes REST APIs for integration with other systems, allowing for programmatic JCL validation and retrieval of results. The system requires network ports for communication with LDAP servers, Db2 databases, and other z/OS components.

Frequently Asked Questions

What are the primary functions of IBM Z JCL Expert?

IBM Z JCL Expert validates JCL syntax, checks for dataset existence, verifies Db2 plans, and identifies security violations before job submission. It helps prevent batch job failures due to common JCL errors.

How does IBM Z JCL Expert validate JCL syntax?

The tool analyzes JCL statements, ensuring they adhere to z/OS syntax rules. It identifies misspelled keywords, incorrect parameter values, and missing required parameters.

How does the tool check for dataset existence?

It verifies that datasets specified in the JCL exist and are accessible to the job. This prevents abends caused by missing or unavailable datasets.

What Db2-related checks are performed?

The tool checks if the Db2 plans referenced in the JCL are valid and available. This prevents job failures related to Db2 connectivity or plan issues.
