Find the plans and packages the bind decks declare

Recipe IDio.moderne.mainframe.db2.FindBindChain

Artifactio.moderne.recipe:recipes-mainframe

Report the chain a bind deck writes down and mark every card that writes it: the plan, the packages its PKLIST may run, the collection each package lands in, the DBRM it is bound from and the program that DBRM was precompiled from, with the job whose step reads the deck. Nothing else in an estate holds the chain — the COBOL never names its package and the JCL never names its plan — and a deck bound in the job stream is read as one too. A second table reads the same binds from the package's side, so that which plans may run a package is a lookup rather than a search: a plan lists either the package outright or its whole collection with *, and only expanding the second says what a package change reaches. AnalyzeBindChain answers the same question and changes nothing.

Data tables

DB2 bind chain

io.moderne.mainframe.analysis.table.Db2BindChain

What each bind card declares, one row per plan or package it names: the deck it is written in, the job that runs that deck, the collection the package lands in, the DBRM it is bound from and the program that DBRM was precompiled from. The deck is the only place the chain from a plan to the program that runs under it is written down — neither the COBOL nor the JCL says any of it.

Column	Description
Deck	The member the deck is: a bind library member under its own name, or the job the deck is written in the stream of.
Deck path	The file the card was written in.
Line	The one-based line of that file the subcommand begins on, counting from the top of the job for a deck written in-stream.
Command	BIND where the card makes the object, REBIND where it names one that already exists. Only a BIND says what an object is bound from.
Binds	Whether the card binds a PLAN or a PACKAGE.
Plan	The plan, empty for a package bind. A plan is what a batch step names in RUN PROGRAM(...) PLAN(...) and what the CICS resource definition names.
Collection	The collection the packages are bound into, empty for a plan bind. This is the name an environment varies: the same deck binds into another collection on another subsystem.
Package	The package, empty for a plan bind. * where a REBIND names every package of the collection rather than one.
DBRM	The DBRM member the package is bound from, from MEMBER. Empty for a plan bind and for a REBIND, which is bound from whatever it was bound from before.
Program	The program the DBRM was precompiled from. A DB2 precompile writes the DBRM under the program's own name, so the DBRM member, the package and the program are the same word — this is the join from a plan to the code that runs under it.
Program path	The program's file, empty where no program of that name was read. A bind for a program nobody supplied is how a gap in an ingestion shows.
Package list	The packages a plan may run, from PKLIST, as written: an entry names a collection and either one package or * for all of them. Empty for a package bind.
Qualifier	What unqualified table names in the package resolve to. This is the schema the SQL in the program actually reads, which the program never names.
Owner	The authorization identifier the object is owned by.
Job	The job whose step runs this deck, empty where no job read here does. A deck run by two jobs has a row for each.
Step	The step of that job, which is where the bind is placed among the compiles.

DB2 package plans

io.moderne.mainframe.analysis.table.Db2PackagePlans

The bind chain read from the package's side: which plans may run each package, and so which plans a change to the program behind it is felt under. A plan lists either the package outright or the whole collection with *, so the plans a package runs under are written down nowhere one name at a time.

Export after a run

mod study . --last-recipe-run \

Column	Description
Collection	The collection the package is bound into.
Package	The package.
Program	The program the package is bound from, which is the DBRM member of the same name. Empty where no bind read here says what the package holds.
Plan	A plan that may run the package. Empty where none read here lists it.
Listed as	PACKAGE where the plan's PKLIST names the package outright, COLLECTION where it names the collection with * and so picks up every package bound into it, NOT_LISTED where no plan reaches it.
Package deck	The deck the package is bound in.
Plan deck	The deck the plan is bound in, which is often not the one the package is bound in.

Source files that had results

org.openrewrite.table.SourcesFileResults

Source files that were modified by the recipe run.

Export after a run

mod study . --last-recipe-run \
  --data-table org.openrewrite.table.SourcesFileResults

Column	Description
Source path before the run	The source path of the file before the run. null when a source file was created during the run.
Source path after the run	A recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Parent of the recipe that made changes	In a hierarchical recipe, the parent of the recipe that made a change. Empty if this is the root of a hierarchy or if the recipe is not hierarchical at all.
Recipe that made changes	The specific recipe that made a change.
Estimated time saving	An estimated effort that a developer to fix manually instead of using this recipe, in unit of seconds.
Cycle	The recipe cycle in which the change was made.

Source files that had search results

org.openrewrite.table.SearchResults

Search results that were found during the recipe run.

Export after a run

mod study . --last-recipe-run \
  --data-table org.openrewrite.table.SearchResults

Column	Description
Source path of search result before the run	The source path of the file with the search result markers present.
Source path of search result after run the run	A recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Result	The trimmed printed tree of the LST element that the marker is attached to.
Description	The content of the description of the marker.
Recipe that added the search marker	The specific recipe that added the Search marker.
