the system operator enters the task identification given in

Usingthe SameTerminalwith DFF and Non-DFFPrograms
A terminalattributesset (definedat assignment
time with
the TERMATTR assignment
control statement)is in
effectwhen a terminalis communicating
with user'sprogramunderthe CCP. Therearea numberof waysof controlling the attributesset of a terminal:
1.
The first TERMATTR statementassigned
to a terminal in an assignment
set is the defaultattributes
set of a terminal. Whenneitherof the followingtwo
methodsare used,this is the attributesset in effect
for theterminal.
2.
The attributesset of a requiredterminalcan be
specifiedfor the terminalduringits attachmentto
the programvia the programassignment

of an
end-of-jobconditionor a release

lseeIBM System/3 Communications Control Program
Programmer'sReferenceManual, GC21-7579),the
defaultattributesset is in effect.
3.
The attributesset can be specifiedfor the terminal
duringits attachmentto the programvia the Acquire

Manual, GC21-75791
with the set terminalattribute
modifier. A terminalalreadyattachedto a program
with one attributesset can be re-acquired
to change
the attributesset. The defaultattributesset is in
effectwhen the terminalis no longerattachedto the
program.

at startup of the CCP (seeSfartup Procedurein the IBM

1.
A samplecontrol statementdeck is punchedfrom the

2.
The sampledeck is modifiedby the userto his speci_

generation.
3.
A full job streamto accomplishthe necessary
functions is punchedfor the user.

STORAGEUTILIZATION
This discussion
is intendedasa summaryof techniquesfor
improvingCCPperformance(response
time) and CCpmain
storageutilization. ln somecases,
techniquesfor improving
CCPperformanceresult in increaseduseof main storage.
On the other hand,techniques
for savingmain storagespace
may result in somewhatslowerperformance.The proper
balancingof thesetwo factorsfor a particularinstallation
dependson the appricationrequirements
of the instailation
and the hardwareresources
availableto the installation.
Analyzingthe applicationmix of a particularinstallation
will helpdeterminerequirements
for performanceand main
storageutilization. ln general,applicationsthat call for
cpntinuousand prolongedinteractionbetweenthe terminal
operatorand the system,suchasorder_entry
applications,
requireminimum response
time so the operatorcan be as
productiveas possible.lnquiry applications,
on the other
hand,might not requiresuchrapid response,
because
operator interactionwith the systemis not likely to be
continuous,and operatorproductivityis not likely to be as
dependenton the response
time of the system.Thus,when
the predominanttype of applicationbeingrun underthe
CCPis order-entry,systemdesignchoicescan be weighted
in favorof improvingresponse
time, evenif it costsmain
storagespace.Whenthe predominanttype of application
is inquiry,systemdesignchoicescan favor savingmain
storagespace.
ResidentAccept: The ACCEpT operandof the $EFAC
generationstatementspecifieswhether accept-input
operationsareto be handledby code residentin main
'
storageor by a transient. Residentaccept(ACCEPT_YES)
reducestransientareacontentionand providesfasteraccess
to data. lt is especially
effectivefor singlerequesting
terminal(SRT)pregysmtype operations.
Resident DFF Format lndex (5ZM-SC2 onty): The
DFFINDX operandof the systemassignment
statement
specifies
whetherthe DFF format index built by startupis
to be residentin main storage.Residentindexesreducethe
time requiredto locatea DFF format. lt is especially
effectivefor singlerequesting
terminal{SRT)programsthat
useDFF type operationsand pRUF type programs.

built in main storageif the externalpointerlist is built and
there is room for indexes. Refer to External pointer List
for more information.
Resident OPEN/CLOSE: (57M-SC2 onty): The RESOpN
operandof the $EFAC macrofor generationcauses
$CCROCto be loadedduringstartup. This eliminatesthe
needto call transientsfor allocateopen and closefunctions
underCCP. In an RPG ll programwith card input and
index loadfile output, the residentmodulesaveslg
transientcallsfor one programrequest.For sort with one
input and one output file, the residentmodulesaves3g
transientcallsfor eachprogramrequest.However,resident
open/close
requires55 bytesin $CC4#1and 10K bytesof
storageto be allocatedto the UpA.
ResidentProgramRequat (S704-SC2only): The RESREO
operandof the $EFAC macrofor generation
causes
$CCRpR
to be loadedduringstartup. This eliminatesthe needto call
transientsfor CCPprogramrequestfunctions. For an SRT
programrequestor a nonactiveMRT programrequest,four
transientloadsaresaved.For an activeMRT programrequest,
threetransientloadsaresaved.Threetransientroadsarearso
savedeachtime the systemoperatorwantsa programrequest
(PF9 key). Residentprogramrequestalsosaves
two transient
loadsfor eachsystemor terminaloperatorcommandthat
is entered. lf RESREQ-yESis specified,$CCRpRoccupies
4K bytesof storage,which would otherwisehavebeen
allocatedto the UPA.
The followingsystemdesignconsiderations
and techniques
can be usedto improveCCp performance
and/or main
storageutilization:
ResidentPolling: The RESPOLoperand of the $FBSC
generationstatement(seeindex entry) specifieswhether
BSCpollingmodulesareto be residentin mainstorage
ratherthan be executedastransients.Residentpolling
(RESPOL-YES)
is especiallyimportantwhen both DSM
partitionsareactiveto ensuregood response
time. lf resident pollingis not used,the CCpcan be preventedfrom
pollingwhen the non-CCPprogrampartitionis usingthe
DSMtransientarea(for example,for disk access).
Placementof Filesand programson Disk: CCp performance
canbe improvedthroughcarefularrangement
on disk of
DSMand CCProutines,$CCPFlLE,userapplicationprograms,3270 displayformats,and datafiles. Theseelements
of the systemcan be arrangedin sucha way asto keepdisk
access
mechanismmovementat a minimumduringCCp'
operation,thus improvingdisk access
speed.Dualspindle
systemsor the 5445 allow moreflexibility in arrangement
of
theseelementsthan singlespindlesystems.
DFF Buffer Support (5204-SC2only): Specify an optional
DFF bufferfor eachBSCline usingDFF to improveper_
formanceby allowingup to four DFF userpUTsto be
scheduled
in variousstagesof transmission
at any given
time. Seel8M System/3CCp SystemDesignGuide, GC2l5 1 6 5f o r a d d i t i o n ailn f o r m a t i o n .
