Parameter in IEASYSxx

IPS=xx

Notes

The IPS contains five catagories of information.  They must be specified in the order shown.

 

1. Service definition coefficients:

[CPU=xx.x] [IOC=xx.x] [MSO=xx.x]

 
2. Workload levels

WKL=(xxx,xxx [,xxx])

 
3. Performance objectives

OBJ=xx, SRV=(xx [, . . .])

 
4. Domains

DMN=xxx,CNSTR=(xxx,xxx,xxx)

 
5. Performance groups

PGN=xx, (DMN=xx, OBJ=xx, DUR=xxxxxxxxx

                    [,UNIT=x,] [,ISV=xxxxxx] [,RTB=x]

                    [,APG=xx] )

               [( . . .)]

 

 

Syntax

  • Comments are permitted wherever blanks are allowed.

  • The general format of a comment is:  /* comment text */

Parameters

Keyword Meaning

Value

Range

Default

Value
APG

Specifies the dispatching priority within the APG range that will be assigned to a transaction.  The APG is divided into three distinct groups:

  • Mean-time-to wait   0 - 6

  • Rotate                     11

  • Fixed                       7-10, 12-15

 0-15 6
CNSTR

Specifies the constraints of a domain, that is , the minimum MPL, the maximum MPL, and the weighting factor, respectively.  All three must be specified.  The value ranges for each are:

  • minimum MPL          0-255

  • maximum MPL         0-255

  • weighting factor         1-255

 (see left) none
CPU

Indicates the number by which accumulated CPU service units will be multiplied.

 

 0.0-0.9 1.0
DMN

Specifies a unique number that is used to associate a domain with a transaction.

 

 1-128
DUR Specifies the length of the performance group period in units indicated by the UNT keyword.

0-999999999

or

0-999999K

 none
IOC

Indicates the number by which accumulated I/O service units will be multiplied.

 

 0.0-99.9 1.0
ISV The interval service value specifies the minimum number of service units that a transaction should receive during each interval of real storage occupancy.

100-999999

or

100-999K

 

 100
MSO

Indicates the number by which accumulated storage service units will be multiplied

 

 0.0-99.9 1.0
OBJ

Specifies a unique number that associates the performance objective with a particular period in the processing of a transaction.

 

 1-64 none
PGN

Specifies a unique identifier for a performance group definition.  This number is used to associate a job, job step or time-sharing session with the respective performance group.

 

 1-255 none
RTB

Specifies the response/throughput bias for a particular performance group period.

 

 0-1 0
SRV

Specifies the service rates that define performance objectives.

 

 0-9999 none
UNT

Specifies the units for the DUR parameter.  "S" indicates service units, "R" indicates real time in seconds.

 

 S,R S
WKL

Specifies a series of positive number of increasing value.  They provide a reference for defining performance objectives.  There can be up to 32 numbers in any workload level specification.

 

 1-128 none
CPU

Specifies the weighting factor by which the recommendation of the CPU load adjusting function is to be multiplied, when an address space is evaluated for swapping.

 

 0.0-9.9 0.1
IOC

Specifies the weighting factor by which the recommendation of the I/O load adjusting function is to be multiplied, when an address space is evaluated for swapping.

 

 0.0-9.9 0.1
ERV

Specifies the "enqueue residence value".  This is a multiplication factor used to calculate the amount of task execution time during which an address space should not be swapped out.

 

 0-999999 1
