Contents 1 Introduction 2 Reasons 3 RDO 4 Activate/Install

Introduction

This feature was introduced with CTS 3.2

Reasons

1. 7*24 Support was main reason
2. Addition to the static DFHRPL
3. Very flexible way for application load libraries
4. Easy to use/setup
5. Easier rollout/backout of application changes

RDO

You can use CEDA to define a set of libaries (old load-modules or new program objects)

!DEF LIB
!OVERTYPE TO MODIFY                                        CICS RELEASE = 0650
! CEDA  DEFine LIbrary(          )
!  LIbrary      ==>

!  Critical     ==> No                 No ! Yes

1. Choose a non existing DD-Name
2. Number 10 is reserved for DFHRPL. 1-9 is for libs before DFHRPL and 11-50 for addtional libs after DFHRPL

Activate/Install

You will see a lot of messages in the MSGUSR like this
