JCL-QA is a program product designed to scan individual JCL job streams, entire JCL libraries, or job streams extracted from job scheduling systems. The product can be used to enforce installation standards, or perform a system validation test. The system validation tests can be performed on either the local system, or remote systems that are also running JCL-QA.
Each job stream is driven through the operating system's converter/interpreter program to expand the JCL. The operating system builds internal control block structures for each input job stream. JCL-QA can then process these control blocks and drive them through validation routines and/or installation rules for standards enforcement. When processing multiple input job streams, the jobs can be "ordered" and JCL-QA can simulate catalog and VTOC updates occurring between the scanned job streams.
The product can be used from ISPF or run as a batch job.
JCL-QA is based on the JCL scan facility used by the MON-Snapshot to scan and report on JCL found in PDS and sequential data sets. JCL-QA is an enhanced version of the original JCL scan facility. The product has been designed to simulate the job flow found in a batch window, and to perform a series of tests on the job streams to validate that the jobs will run on the target system. The product:
ensures that the programs executed by steps are found in the appropriate STEPLIB, JOBLIB or system libraries
validates volume and unit names
validates SMS construct names used by the JCL
validates data set availability and usage
simulates passed data set usage in a job
simulates catalog activity as one or more jobs are "executed"
can be used to enforce installation JCL standards
can be executed as a batch job or from an ISPF session
can simulate jobs on remote systems
High speed JCL validation minimizes overnight production impact
Affordable pricing (versus established product offerings)
Ensures system compatibility by utilizing the operating system's converter/interpreter program to expand the JCL
Provides maximum flexibility utilizing modern rules language
Proven code – based on existing MONitor product

SCC Monitor has had the ability to scan JCL since the late 1990s. Originally, this facility was used by the DTS ABARs backup product (ABC) to scan application JCL to extract data set usage information. During the past few years, several customers and DTS distributors have asked for the JCL scan feature to be upgraded into a full-fledged JCL validation product. In early 2010, DTS developers started a low-priority project to create MON-JCLQA. After several years of part-time work, DTS released MON-JCLQA in late 2011.
