4. XINFO and CICS XINFO´s CICS scanner analyzes the CSD file:
Complete overview about all CSD data
Complete Cross Reference, e.g.
Batch and CICS
COBOL and CICS
PL/1 and CICS

5. Why analyzing the CSD file?
“Normal” IT personal like production planners have no detailed knowledge about internal structures of CICS
“Normal” IT personal like operators have no access to CICS data
A standard “Cross Reference” for CICS does not exist
Typical questions like “which CICS programs are currently using file A.B.C” cannot be answered easily

MAPSET
FILE (DD and DSN)
Transient data Queue

7. XINFO and CICS Some examples:
Which programs belong to which transactions?
Which programs are running below the 16M line?
Which programs are running in a remote CICS?
