TSO/ISPF – versus RDz + COBOL Analytics Tools – For DevelopmentTSO/ISPF – versus RDz + COBOL Analytics Tools – For DevelopmentUse Case ScenariosUse Case Scenarios TSO/ISPFTSO/ISPF RDz + RAARDz + RAA

We need to ensure that the unit and integration test data beds have sufficient Code Coverage Analysis before moving the application into production

Virtually impossible to achieve with ISPF search techniques

Debug Tool

We would like to document the following for all new applications:JCL run-stream jobs, Procs and Parmlib dataData Flow Diagram – all QSAM/VSAM files, DL/I databases and DB2 Tables/ViewsA process flow diagram – all of the programs in each jobA list of all programs in the application. For each program:

A graphical/hierarchical structure chart of the flow of control A list of all files accessed A list of all copybooks

If online program: Show the transaction flow – front-to-back List associated system resources (CICS/IMS table gens) List online screens – and which programs send and receive them

Java / JavaScript web pages that access the application’s: Process (COMMAREA or LINKAGE) Data

A set of analysis metrics – that calculate overall code complexity

Manual, iterative, costly, error-prone and time-consuming ISPF:

SearchEdit – document with comments

Note graphical documentation is (for all practical purposes) not supported

RAA Reports

We’re planning on transforming several key VSAM and QSAM files into DB2 tables. In order to cost and scope this effort, we need to know:

What JCL will have to be changedHow many temporary (&&Temp and SortWork) files are affected (for QSAM)All areas of the COBOL programs that access the VSAM file that will have to be re-writtenFDsCopybooks and all other related WORKING STORAGE structures and variablesLinkage SectionPROCEDURE DIVISION paragraphsAll calls to sub-routines passing values

Manual, iterative, costly, error-prone and time-consuming ISPF:

SearchEdit – document with comments

Standard (in-the-box) RAA reports

During the development of this app, the users realized they forgot about a key piece of information that will be added to a DB2 table. We need to know what COBOL/PL1 programs and Java entities (Servlets, JSPs and EJBs) reference this table – as they will more than likely need process the information in the new table/column

Standard (in-the-box) RAA reports

Debug an error that occurred during application development unit-test – including but not limited to:Data exceptionOperation exceptionArithmetic exceptionDivide By ZeroJob Cancelled/Timeout (infinite loop)Module Not Found IMS Database Error or VSAM File Error Condition (invalid status code)DB2 / SQL Error Condition Incorrect Output (No ABEND Code – just incorrect results)

TSO/ISPFTSO/ISPF RAARAA

1. Use a 3rd Party tool to determine what DB2 PLANS reference the table. Or using SPUFI/QMF, write and execute a number of DB2/DBA-level System Catalog queries – referenced catalog tables include (but are not limited to): SYSPLANS, SYSPLANDEP, SYSPACKAGES, SYSDBRMS, SYSTMT & Stored Procedure tables (if they are used)

2. Save the DB2/SQL Statement results to a TSO file – or printout. On an average large-scale z/OS production system, this could be well over 100 entries.

3. For each SQL Statement (for each of the (average) over 100 results listed in step 2)Open and browse in the COBOL sourceFind the statementFind the host variable for the column to be enlargedNote the DCLGEN record name (will have to be re-created)(The hard part) Do iterative, recursive, discrete and explicit TSO text searches, to list all COBOL variables that this field interacts with (essentially, all COBOL "data manipulation" and "data comparison" statements) that will need to be modified. Here is a partial list of explicit keywords, each if found factors into the recursive search:

MOVE MOVE – and all variations of MOVE MOVE such as MOVE CORRESPONDING MOVE CORRESPONDING – which means you now must trace GROUP moves, not just the individual field itself (if a numeric field) ADD, SUBTRACT, DIVIDE, MULTIPLY, COMPUTE, SET IF, EVALUATE, INSPECT (WHEN clause) Literals that will need to be changed – esp. if part of comparisons STRING, UNSTRING STRING, UNSTRING and Reference Modification statements CALL USING/ENTRY USINGCALL USING/ENTRY USING WRITE, READWRITE, READ A host of LE calls and COBOL intrinsic functions PERFORM UNTILPERFORM UNTIL loops with (if a variable is part of PERFORM USING) … more

Disregard all hits (false-positives) in * comment linesRepeat the above for each field affected (all fields related to any changed field become part of a linked list or, "association chainassociation chain").Be careful not miss any fields – anywhere in the association chain – this gets very difficult, when fields are externalized – see steps, 4 9 below)List all of the Records affected in the FILE SECTION, or DL/I segments, or other DB2 DCLGENs

Look for QSAM – VSAM file - DL/I database and DB2 table write operationsCreate a list or printout of all affected fields and records

4. For all File Records found in step three affected Look for QSAM – VSAM file - DL/I database and DB2 table write operationsIf DB2 Table SQL statement – return to Step 1If any records are QSAM/VSAM files – including SORT/MERGE, &&TEMP files, SYSOUT, potentially log files:

Find all JCL associated with the files The LRECL and BLKSIZE Parameters – that will need modification. SPACE parameter might need to be recalculated and extents If they are VSAM files or IMS databases built on VSAM files:

– you will need to modify the IDCAMS utility JCL used to DELETE/DEFINE the datasets If there are DL/I databases, you will have to change the DBD and modify the DL/I database – deleting and reloading (let's hope not)

5. If the field is passed from one program to another in CALL … USING/ENTRY USING Repeat steps 3,4 and this step 5 – for all affected programs

6. If the field – or any associated field anywhere in the chain participates in printed reports:Recalculate print columns to line up the fields according to the required report output

7. If the field – or any associated field anywhere in the chain is used in a CICS or IMS TM applicationRecreate the screen UI – modify the BMS or MFS macrosModify all COBOL variables affected by changes to the screen I/OFor CICS, you will have to factor in changes to the TS QUEUEs and Transaction Work AreasFor older IMS conversational programs, you will have to factor in changes for the IMS SPA definitions in the SYSGEN

8. (And here's the killer)(And here's the killer) For every file that any field in the chain is written to, you will need to trace each file through every JCL job stream and:Repeat steps 3, 4, 5, 6, 7 and 8 for every program/file/field combination - and every new association chain producedRepeat steps 3, 4, 5, 6, 7 and 8 for every program/file/field combination - and every new association chain produced
