What you receive with CICS TS
Because theelementsof CICSTSareintegratedintoa singlepackage,youare expectedto installtheentireproduct.
You caninstallCICSTSusingoneof severalIBMpackages.Twoofthese packages areavailableat noadditionalchargewhenyoulicenseCICSTS:(1) ServerPac,thesystem replacedeliverable,or (2)CBPDO.
There isnostand-aloneproducttapefor CICSTS,andthereisnoCustomBuilt InstallationProcessOffering(CBIPO).
Because oftheoveralleaseof installing,IBM recommendsthatyouchoose ServerPac,if possible.
