  1. Ins and Outs of AllFusion Endevor ACM option Focus Area:App Life Cycle Mgt Session Code:ACC39SN

  2. Abstract This session will give an overview of ACMQ and what has changed in ACMQ release 4.0. We will discuss the implementation path and we will also take a closer look at LDS files. Finally we’ll answer some of the most frequent questions that are asked about ACMQ and its usage

  3. Agenda • What is ACMQ (release 3.9 and 4.0) • A sample Release 4.0 online query • CONSCAN / CONRELE • Initial implementation / migration • VSAM-LDS, the foundation of ACMQ • File maintenance • V-FAQS

  4. Release 3.9 and 4.0 The Tool • Only query panels • Fast where used query • A batch query program • A utility program (known as ORPHDEL)

  5. Release 3.9 and 4.0 The Foundation • Requires ASCM=YES in C1DEFLTS • 2 LDS files ACMROOT and ACMXREF defined in C1DEFLTS • ROOT contains references, XREF contains relations between them • Automatic update of ROOT/XREF at the end of processor execution

  6. Release 3.9 and 4.0 The Foundation • ACMQ contains a subset of the component lists: The input component information • Anything in ACMQ can also be found in an element’s component list • Lightning/frightening(ly) fast • Proven to be Robust due to solid Enq/Deq mechanism to serialize access

  7. New in release 4.0 • Intuitive screens (finally, sigh..) • Fastest version ever • No longer a product option • Endevor Internal Use of ACMQ • SCL batch query option Filter query results (batch only)

  8. New in release 4.0 • Automatic queries ISSUE_ELEMENT_REFERENCED_MSGS= (ON|OFF,QE,BATCH) • Automatic Orphdel • Endevor Alternate-ID support

  9. Agenda • What is ACMQ (release 3.9 and 4.0) • A sample Release 4.0 online query • CONSCAN / CONRELE • Initial implementation / migration • VSAM-LDS, the foundation of ACMQ • File maintenance • V-FAQS

  12. Agenda • What is ACMQ (release 3.9 and 4.0) • A sample Release 4.0 online query • CONSCAN / CONRELE • Initial implementation / migration • VSAM-LDS, the foundation of ACMQ • File maintenance • V-FAQS

  13. CONSCAN & CONRELE • ACMQ is an excellent repository for your element related meta-data • In your processor, extract the meta-data using a source scanner to (CONSCAN) • Use CONRELE to relate the meta-data to the element and thus get it into ACMQ

  14. Agenda • What is ACMQ (release 3.9 and 4.0) • A sample Release 4.0 online query • CONSCAN / CONRELE • Initial implementation / migration • VSAM-LDS, the foundation of ACMQ • File maintenance • V-FAQS

  15. Initial Implementation • 2 simple steps: • BC1JACMD: Defines the files • BC1JACML: Prints your component lists, this may be SLOW Schedule daily file reorganization

  16. Upgrade from release 3.9 • Backup your files • Run release 4.0 BC1JACMO to convert the internal file format • Do not share with release 3.9 users

  17. Agenda • What is ACMQ (release 3.9 and 4.0) • A sample Release 4.0 online query • CONSCAN / CONRELE • Initial implementation / migration • VSAM-LDS, the foundation of ACMQ • File maintenance • V-FAQS

  18. LDS overview • VSAM(?) LDS • 4K records(?) only • Data in virtual means page dataset • Means extremely fast(!) • Only updates get written – real paging • No file reorganization like for KSDS • No LSERV or RLS support

  19. LDS overview • Programmed access • ALESERV • DSPSERV • DIV • IDCAMS support: • DELETE/DEFINE • REPRO OUT (always) • REPRO IN (only for newly defined files) • PRINT

  20. Agenda • What is ACMQ (release 3.9 and 4.0) • A sample Release 4.0 online query • CONSCAN / CONRELE • Initial implementation / migration • VSAM-LDS, the foundation of ACMQ • File maintenance • V-FAQS

  21. File Maintenance • Both files contain 2 logical areas : • sorted • unsorted • At least once daily an ORPHDEL (BC1JACMO) to integrate unsorted data in sorted area for faster lookup/inserts • AUTO_ACMQ_FILE_REORG, by default a reorg every 5000 updates

  22. File Backup • Are backups needed? • Both files at the same time ! • Use DISP=OLD • During expected low activity, maybe immediately before/after ORPHDEL • Verify listcat data. Secondary extents are supported but not recommended

  23. Agenda • What is ACMQ (release 3.9 and 4.0) • A sample Release 4.0 online query • CONSCAN / CONRELE • Initial implementation / migration • VSAM-LDS, the foundation of ACMQ • File maintenance • V-FAQS

  24. Very - FAQs • I cannot find my ‘baby’ • What’s an ‘orphan’ • ACMQ retains references to a copybook that I just deleted, even after ORPHDEL • The A-B-C scheme: Indirect references (aka ‘clones’)

  25. I don’t find what I’m looking for • A lot of potential causes: • Check spelling • Don’t ask where used for a program, rather for a copybook • Related Comments and Text is case sensitive by default unless MONOCASE-SEARCH is set in ENCOPTBL • Don’t specify ENV, STG, SYS, SBS, TYP on the query panel, leave everything to *

  26. I don’t find what I’m looking for --------------------------------- ACM QUERY ------------------------ OPTION ===> _________________________________________________________ NO MATCHING ENTRY FOUND BLANK - Perform Element query C - Perform Comment query M - Perform Member query O - Perform Object query ELEMENT/MEMBER ===> CIMDPARM ELEMENT Query Information: Query Options: ENVIRONMENT ===> PROD WHEre-used/COMponents used => WHE SYSTEM ===> * Foreground/Batch Mode ======> F (F/B) SUBSYSTEM ===> * Create GENERATE SCL ======> N (Y/N) TYPE ===> * STAGE NBR ===> 2

  27. I don’t find what I’m looking for • By over-qualifying an element, you really ask a different question than you intend: Which element’s component lists have a reference to component CIMDPARM used out of PROD/STG2 You probably mean to ask, which component lists have a reference to CIMDPARM which is now in PROD/STG2

  28. Very - FAQs • I cannot find my ‘baby’ • What’s an ‘orphan’ • ACMQ retains references to a copybook that I just deleted, even after ORPHDEL • The A-B-C scheme: Indirect references (aka ‘clones’)

  29. What is an ORPHAN Stage-1 Stage-2 Comp-list before Comp-list after COPY-A Elm name/stg COBOL-B STG-1 Comp name/stg COPY-A STG-1 Elm name/stg COBOL-B STG-2 Comp name/stg COPY-A STG-2 COBOL-B Using Generate Processor Orphans in RED

  30. What is an ORPHAN ACMQ root record without relations • COPY-A is in component list of COBOL-B • Scenario-1: COPY-A and COBOL-B get moved to next stage using GEN processor. • Root still contains reference to COPY-A and COBOL-B in stage-1 Both COPY-A and COBOL-B in stg-1 are now orphans.

  31. What is an ORPHAN Stage-1 Stage-2 Comp-list before Comp-list after COPY-A Elm name/stg COBOL-B STG-1 Comp name/stg COPY-A STG-1 Elm name/stg COBOL-B STG-2 Comp name/stg COPY-A STG-1 COBOL-B Using Move Processor Orphan in RED

  32. What is an ORPHAN ACMQ root record without relations • COPY-A is in component list of COBOL-B • Scenario-2: COPY-A and COBOL-B get moved to next stage using MOVE processor. • Root still contains reference to COBOL-B in stage-1 COBOL-B is now an orphan BUT COPY-A in stage-1 is NOT an ORPHAN

  33. Very - FAQs • I cannot find my ‘baby’ • What’s an ‘orphan’ • ACMQ retains references to a copybook that I just deleted, even after ORPHDEL • The A-B-C scheme: Indirect references (aka ‘clones’)

  34. ACMQ retains references.. Stage-1 Stage-2 Comp-list before Comp-list after COPY-A Elm name/stg COBOL-B STG-1 Comp name/stg COPY-A STG-1 Elm name/stg COBOL-B STG-1 Comp name/stg COPY-A STG-1 COBOL-B DELETE COPY-A Orphans in RED

  35. Very - FAQs • I cannot find my ‘baby’ • What’s an ‘orphan’ • ACMQ retains references to a copybook that I just deleted, even after ORPHDEL • The A-B-C scheme: Indirect references (aka ‘clones’)

  36. The A-B-C scheme • « Only » for sites using MOVE processors • ACMQ 3.9 « loses » references after move • ACMQ 4.0 « clones » references during search • They are called « Indirect References »

  37. The A-B-C scheme Comp-lists before Comp-lists after Elm name/stg LINK-C STG-1 Comp name/stg COBOL-B STG-1 Elm name/stg LINK-C STG-2 Comp name/stg COBOL-B STG-1 COPY-A COBOL-B LINK-C Using Move Processor Elm name/stg COBOL-B STG-1 Comp name/stg COPY-A STG-1 Elm name/stg COBOL-B STG-2 Comp name/stg COPY-A STG-1

  38. The A-B-C scheme Query results 3.9 Before MOVE action LVL ELEMENT TYPE ENVIRON STG 1 COPY-A COPY ENTRY1 2 COBOL-B COBOLENTRY1 2 LINK-C LINK ENTRY1 After MOVE action LVL ELEMENT TYPE ENVIRON STG 1 COPY-A COPY ENTRY1 2 COBOL-B COBOLENTRY2 Connection with LINK-C now lost

  39. The A-B-C scheme Query results 4.0 Before MOVE action LVL ELEMENT TYPE ENVIRON STG 1 COPY-A COPY ENTRY1 2 COBOL-B COBOLENTRY1 2 LINK-C LINK ENTRY1 After MOVE action LVL ELEMENT TYPE ENVIRON STG 1 COPY-A COPY ENTRY1 2 COBOL-B COBOLENTRY2 *2 COBOL-B COBOLENTRY1 3LINK-C LINK ENTRY2
