Promotion Packages

> New “Kind” of Package Promotion=Y/N set by user on CREATE/MODIFY Panel

> Restrictions Only MOVE actions allowed

Same “From Location” required for all actions

Processor ALLOC=LMAP/PMAP

> New Processor DD Statement Parameter Enables Dynamic Concatenation of Libraries

Based on Current Inventory Location, Map Definition

“LMAP” – Logical Map (STG 1-STG 2-STG 2)

“PMAP” – Physical Map (STG 1-STG 2-STG 1-STG 2)

//SYSLIB DD DSN=NDVR.&C1ENV..&C1STG..&C1SYS.COPYLIB,// ALLOC=LMAP// DD DSN=NDVR.&C1ENV..&C1STG..COMMON.COPYLIB,// ALLOC=PMAP

Product Performance Improvements



Concurrent Action Processing

> “Like Breaking Up a Single Large JOB Into Several and Submitting Them All At Once…”

> Concurrent Action Processing Available For: Batch Element Action SCL

Packaged Element Action SCL

API-Initiated Element Actions (CMEW)

> Actions Executed In Type Sequence If There Are More Tasks Available Than Actions, “Non-

Sequenced” TYPE Actions Used to Maximize Throughput

> Can Reduce Execution Elapsed Time As Much AS 70%!!!



> Setup: CA CCI Spawn Facility Used to Initiate STCs (like CMEW)

– Must Define a CCI Service Definition

Enable Via C1DEFLTS

– SPAWN=Y/N - On or Off

– SPAWNCNT - Default Nbr of Concurrent Tasks

– SPAWNMAX - Maximum Nbr (99) of Concurrent Tasks

– SPAWNPROC - CA CCI Service Definition / JCL PROCLIB MBR

Copy JCL PROC to PROCLIB (“ENDEVOR” supplied with r12)

Requires Global Type Sequencing Implementation (r7)



> External Security Interface (ESI) Can Control Access

> Concurrent Action Processing Requested Via Batch Action or Package Submit Panels

Generates a DD statement //EN$CAPxx (xx = # of tasks)

– If “xx” omitted, C1DEFLTS “SPAWNCNT” value used

– The “xx” value must be within C1DEFLTS “SPAWNMAX” range



> Notes: Execution Messages Grouped and Returned to Initiating

JOB for Reporting

If MAXCC Reached, Gradual Shutdown Occurs

PRINT, LIST, ARCHIVE-File Actions Are Not Spawned

The Product Is I/O-Bound – Concurrent Action Processing WILL NOT DRAIN RESOURCES!



> Notes: Empirical Evidence Indicates 8-10 Spawned Tasks Provide

Optimal Throughput

RLS (or LSERV) Provides a Large “Boost” By Reducing VSAM File Contention

Spawned Tasks Do Not Spawn Other Tasks

– (C1BM3000 executed within a processor)

> CA Was Awarded a U.S. Patent For This technology!


Batch Element Action Submit ISPF Panel

Enhanced Product Functionality



Automatic Version Rolling

> Elements Automatically Roll To Next Version When Level 99 Updated

> Delta Consolidation Option No Longer Necessary (but remains available)

> Eventually, Version Numbers Will Disappear – Leaving Four-Digit Level Numbers

> Maximum Number of Levels is 9999

> Automatic Version Rolling Is Not Optional Can be avoided by using delta consolidation option


Element Delta Level Retention by Age

> Activated by Setting Retention Age on SYSTEM Definition Element Delta and Component List Delta Options can be

set independently

Each defaults to “Off”

> Whenever a Delta Level is Created, “Old” Delta Levels Deleted

> “BC1JRDLT” Utility JOB is Provided to Identify “Old” Delta Levels

Can Be Executed in “Update” Mode to Remove “Old” Levels

CSV Data Extract Utility Enhancements

> Now Supports: CA SCM for Mainframe SMF Activity Data

Element Delta Level Information

Package Ship Information

Completely Revamped Product Installation



Product Installation

> Standard SMP/E Steps RECEIVE

APPLY

Tailor JCL Using a Scan/Replace Utility Program

USERMODs for user tables

> Follows Current CA Standards (Common CSI)

> Base Release and Service Packs – Same Installation Format



> All table source is unloaded into the iprfx.iqual.TABLE library

> The sample application and processor examples are unloaded into the iprfx.iqual.SAMPLE library

> Sample JCL members delivered contain INCLUDE MEMBER=SCMM@LIB statement for STEPLIB/CONLIB concatenation

> Sample JCL members delivered contain INCLUDE MEMBER=SCMM@SYM statement for variable substitution



SCMM@LIB Example:

//STEPLIB DD DISP=SHR,DSN=BST.QA1200.AUTHLIB

// DD DISP=SHR,DSN=BST.C11200.AUTHLIB

//CONLIB DD DISP=SHR,DSN=BST.C11200.CONLIB



SCMM@SYM Example

// SET C@RT=3480// SET D@VOLSER=DVOLSER// SET I@PRFX=BST// SET I@QUAL=C11200// SET P@DISK=SYSDA// SET T@DISK=SYSDA// SET T@VOLSER=B1200C// SET U@PRFX=BST// SET U@QUAL=QA1200



JCL Member Example:

// INCLUDE MEMBER=SCMM@SYM//ENBP1000 EXEC PGM=NDVRC1,// PARM='ENBP1000',// REGION=4096K// INCLUDE MEMBER=SCMM@LIB//SYSPRINT DD SYSOUT=*

Alternate IDImplementation Improvements



Alternate ID Implementation Improvements

> ICHRCX01 Security Exit Removed From Product Reimplementation of the ALTID Facility Precludes Its Need

> USEREXIT Table Enhancement Can Control Use of ALTID for Exits

Can Swap Single USEREXIT TCB or Entire Address Space During Exit Processing (Needed for INTRDR)

> TSO Processor Steps Require “LGNT$$$I/LGNT$$$O” OPENs to Swap TO/Unswap From the ALTID

Causes Security Context of Address Space to be Swapped – Not Just the Task



> Adjustments for RACF “TEMPDSN” Option Option Forces Userid Context At Allocation Time to be the

Same as At Data Set Open Time for Temporary Data Sets

– Causes Problems for ALTID Facilty

– Workarounds: Specify ALTID=N on Processor Step

USE “RACF_TEMPDSN_OPTION=ON” ENCOPTBL Option to Force the Use of “MODHLI” for All Temporary Data Sets (makes them temporarily permanent)

– UNIT Parameter Value for Permanent Data Set Allocation Taken from C1DEFLTS WRKUNIT Specification



> Adjustments for RACF “TEMPDSN” Option Non-CA Processor Programs That Dynamically Create

Temporary Data Sets, But Do Not Delete Them, Cause Problems Due to ALTID/USERID Mismatch

– Correct Defective Program -- Delete the Temporary Data Set It Created Before Terminating

– Specify ALTID=N on Processor Step

Documentation Changes




> The User Guide has been rewritten and provides procedures for tasks performed in foreground, including foreground batch tasks. Other batch tasks are still addressed in the SCL Reference Guide and the Packages Guide.

> The installation steps are now provided in the Implementation Guide. The Getting Started has been eliminated, with relevant information moved to either the Implementation Guide or the Administration Guide.



> The guides are provided in searchable Adobe PDF format. They are no longer provided in IBM BookManager BOO format.

> The CA Common Services CA-L-Serv Technical Bulletin now provided in the Technical Document Index on the product home page on www.Support Connect. It is no longer included with the guides in the documentation set.

> The following guides have been eliminated: Quick Reference Guide for Administrators and Quick Reference Guide for Users.

Conversion & Compatibility Issues



Conversion Requirements

> None!


Backward Compatibility

> Promotion Packages New promotion package record types will be orphaned

– Delete promotion packages using r12

> Greater Than 99 Element Delta Levels r7 cannot “handle” this

– TRANSFER / MOVE w/o HISTORY using r12

> Usage of ALLOC=LMAP/PMAP in Processors r7 cannot execute processors with this feature enabled

– Remove the ALLOC=LMAP/PMAP parameter
