CA Pro-Build for DB2 Modernization Guide

CA Pro-Build for DB2 provided an interface for accessing DB2 databases from CLIST and REXX environments on z/OS. It allowed users to build and execute DB2 queries and manage database interactions within these scripting environments.

CA Pro-Build for DB2 was primarily a toolset that extended the capabilities of CLIST and REXX scripting languages to interact with DB2 databases. It provided a set of commands and functions to facilitate database access and manipulation.

Organizations that relied on CLIST and REXX scripting for automating tasks and interacting with DB2 databases on z/OS would have used CA Pro-Build for DB2. These were often larger enterprises with established mainframe environments.

Companies would have considered CA Pro-Build for DB2 when they needed to integrate DB2 database access into their existing CLIST and REXX scripts, particularly for automating tasks or generating reports. However, given its 'Not Supported' status, migration to a supported alternative is necessary.

Alternatives to CA Pro-Build for DB2 include CA RC/Query (its direct replacement), IBM DB2 Query Management Facility (QMF), and other modern database access tools that support scripting and automation on z/OS.

CA Pro-Build for DB2 required a z/OS environment with DB2 installed and configured. It also needed CLIST and REXX interpreters to be available for executing the scripts that utilized its functions.

CA Pro-Build for DB2 ran within the z/OS environment, typically in an LPAR (Logical Partition). It was dependent on z/OS services and DB2 subsystems for its operation.

The product extended CLIST and REXX by providing specific commands and functions to interact with DB2. These commands allowed users to execute SQL queries, retrieve data, and perform other database operations from within their scripts.

Common operations included connecting to DB2, executing SQL queries, fetching data into REXX variables, and disconnecting from the database. Specific commands would have been used for each of these operations, but the exact syntax is unavailable due to the product's status.

The business value of CA Pro-Build for DB2 was in enabling automation of DB2 database tasks using CLIST and REXX scripting. This allowed organizations to streamline processes, generate reports, and manage data more efficiently within their existing mainframe environments.

Without CA Pro-Build for DB2 (or a similar tool), organizations would have needed to use more complex and potentially less efficient methods for interacting with DB2 databases from CLIST and REXX scripts, or migrate to different scripting languages altogether.

CA Pro-Build for DB2 provided integration between DB2 databases and CLIST/REXX scripting environments, allowing for streamlined data access and manipulation. This integration facilitated automation of tasks and reporting.

Security features would have included authentication to DB2, potentially leveraging existing z/OS security mechanisms. Access control would have been managed through DB2's own authorization system.

Access control was likely managed through DB2's built-in authorization mechanisms, which allowed administrators to grant or revoke privileges to users and groups for specific database objects and operations.

Auditing capabilities would have been provided by DB2 itself, which could track database access and modifications. CA Pro-Build for DB2 would have utilized these capabilities to provide an audit trail of database interactions initiated through CLIST and REXX scripts.

Ongoing operational requirements would have included monitoring DB2 performance, ensuring the availability of CLIST and REXX interpreters, and managing user access to DB2 databases. Regular maintenance of the z/OS environment was also essential.

Implementation challenges might have included ensuring compatibility with existing CLIST and REXX scripts, configuring DB2 security, and training users on the new commands and functions provided by CA Pro-Build for DB2. Migrating from CA Pro-Build for DB2 to a supported alternative also presents challenges.

Administrative interfaces would likely have been command-line based, utilizing z/OS consoles or terminal emulators. User management was handled through z/OS security systems and DB2's own authorization mechanisms.
