7.2.3.1.1 SMFTYPE Statement

 The SMFTYPE statement is optional.  This statement is used to
 restrict the SMF record types accepted by a unit to a subset
 of the record types specified on the
 sharedprefix.MICS.GENLIB(VTSGENIN) INPUTSOURCE statement.
 See Section 7.2.2.1 for more information on the VTSGENIN
 INPUTSOURCE statement.
 
 By default, any unit containing the VTS component will accept
 and process all SMF record types in the input data file that
 match the SMF record types specified by the complex level
 VTSGENIN INPUTSOURCE statement.
 
 If you need to implement the VTS component in two or more
 units, use the SMFTYPE statement to ensure that each unit
 processes a specific set of SMF record types.
 
 The SMFTYPE statement has the following format:
 
 SMFTYPE nnn1 nnn2 ... nnn7
 
 where:
 
 nnn1-nnn7   Are any subset of the SMF record types specified
             on the VTSGENIN INPUTSOURCE statement.
 
 There is no default.  If a SMFTYPE statement is not coded,
 all SMF record types specified on the INPUTSOURCE statement
 will be accepted and processed.
 
 The SMF record types coded with the SMFTYPE statement in
 prefix.MICS.PARMS(VTSOPS) must be a subset of the SMF record
 types specified on the INPUTSOURCE statement in VTSGENIN.  A
 maximum of seven record types can be coded.  Coding or
 changing SMF record types on the SMFTYPE statement in VTSOPS
 requires execution of prefix.MICS.CNTL(VTSPGEN).
 
 Example:
 
 A data center has recently consolidated three sites: one with
 an IBM VTS (SMF type 94), and two with StorageTek VSM
 systems. One of the sites with StorageTek is creating SMF
 record type 253 and the other is creating SMF record type
 254.
 
 The site has created three separate units for processing data
 from the consolidated sites, each with a VTS component step:
 
 o Unit A will process the IBM VTS data.
 
 o Unit B will process the StorageTek SMF type 253 records.
 
 o Unit C processes the StorageTek SMF type 254 records.
 
 The complex-level INPUTSOURCE statement must specify ALL
 record types.  The unit level subsetting is achieved using
 the following SMFTYPE statements.
 
   COMPLEX LEVEL
   sharedprefix.MICS.GENLIB(VTSGENIN)
     ...
     ...
     INPUTSOURCE  SMF  94 253 254
     ...
     ...
 
   UNIT LEVEL
   prefix.MICS.PARMS(VTSOPS)
 
     UNIT A
     ...
     SMFTYPE 94
     ...
 
     UNIT B
     ...
     SMFTYPE 253
     ...
 
     UNIT C
     ...
     SMFTYPE 254
     ...
 
 If SMF data is proactively filtered so that the records
 presented to a VTS component are already restricted to the
 record types that you want, no SMFTYPE statement is required.
 The coding of an SMFTYPE statement, however, can act as an
 insurance policy to protect against the accidental inclusion
 of unwanted virtual tape SMF record types in the raw data
 presented to a unit.
