Data Lineage

Trace data from DB2 columns, IMS segments, and file fields through COBOL host variables across programs and copybooks.

Data Lineage in OL AtomIQ traces how data moves from database columns, IMS segments, and file layouts through COBOL host variables and across programs and copybooks.

Capabilities

Interactive lineage tree with source-context preview
Direction-aware usages (read vs write paths)
Entry from DB2 Table Metadata (Track field lineage) and related resource views
Cross-program and copybook tracking for impact analysis
IMS COBOL resolves through a dedicated flavor, with no silent fallback to standard COBOL. Segment GET, ISRT, REPL, and DLET, plus PCB usage, show up as table-side lineage sources alongside DB2 EXEC SQL in mixed IMS-DC programs. DL/I segment fields and CBLTDLI I/O areas stay in the same lineage walk
