Build the resource side of the CRUD matrix

Recipe IDio.moderne.mainframe.analysis.FindResourceUsage

Artifactio.moderne.recipe:recipes-mainframe

Report which programs and jobs reach each file, queue, DB2 table, data set and IMS segment, one row per resource and program carrying the letters of everything done to it. This is the matrix FindResourceCrud and FindBatchCrud build, turned on its side: theirs answers what one program touches, this one answers who else touches a store, which is the question asked before a file is changed or retired. The same rows are pivoted rather than the portfolio being read again, so a VSAM file read through CICS in one program, read natively in another and allocated by a job under its real data set name is three rows about one store — and every segment a DL/I call names carries its own letters, the last one written and the ones above it read to reach it.

Resource usage matrix

io.moderne.mainframe.analysis.table.ResourceUsage

Which programs and jobs reach each file, queue, DB2 table, data set and IMS segment, one row per resource and program, with the letters of everything they do to it.

Export after a run

mod study . --last-recipe-run \
  --data-table io.moderne.mainframe.analysis.table.ResourceUsage

Column	Description
Resource kind	Whether the resource is a file, a temporary storage or transient data queue, a DB2 table, an IMS segment, or a data set, a generation or a library member the JCL names.
Resource	The resource by the name the outside world knows it by: the ASSIGN name of a native file, the data set name behind a DD, and the resource's own name for a CICS file, a DB2 table or an IMS segment.
Program	The program that reaches it, empty for a data set a job allocates and no program among the sources read opens.
Job	The job whose step binds it, empty where the program names the resource itself.
CRUD	The letters of everything done to the resource — C, R, U, D, in that order. Empty where a job names a data set and nothing says what becomes of it.
Via JCL	Whether the row was read from the JCL rather than from the program. A JCL row names the data set as the installation knows it; a program row names what the program itself calls the store.
