PQ98426: KEYWORD T2CHK= CONTROLS T2CHK PARAMETER IN THE SINGLE STEP HASH CHECK OPTION INVOKED FROM HP IMAGE COPY V3R2.

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• A new optional keyword T2CHK=(T2num,T2len) will be added
  to the ICEIN control statement. It is the same function as
  OPTION T2CHK control statement in the PROCCTL data set for
  HD Pointer Checker.

  HPIC provides new keyword parameter T2CHK= that is supported in
  order to specify the two threshold values that will define how
  the slack bytes or unknown data is treated as T2 records.
  
  The maintenance PQ98276 for IMS High Performance Pointer
  Checker for z/OS Version 2 is required for using the T2CHK
  function.
  

Problem conclusion

Temporary fix

Comments

• FABJMAIN, FABJINT1, and FABUITCT have been modified to pass the
  T2CHK value to HPPC.
  
  FABJPARM, FABJPRM2, FABJSTMD, FABJSTMP, FABJTGEN, FABJCSIF,
  FABJMRGE, and FABJBLKD have been modified to support the new
  keyword parameter T2CHK=.
  
  The following modules have been reassembled.
    FABJACQG  FABJDBDN  FABJDCTL  FABJDPS9  FABJMDP8  FABJRCH9
    FABJCMDB  FABJDBD7  FABJDMPN  FABJDPUT  FABJMDP9  FABJRDB7

  ========================
  IMS High Performance Image Copy for z/OS Version 3 Release 2
  User's Guide: Document Number: SC18-7617-01  ( SC18761701 )
  should be changed as follows:
  
  2.0 Operating Instructions
   2.3 Input
    2.3.5 ICEIN Keywords
  |  2.3.5.49 T2CHK=
  | The T2CHK keyword specifies the two threshold values for HDPC
  | HASH pointer check that will define how the slack bytes or
  | unknown data is treated as T2 records.
  | +---------------------------------------------------------+
  | | T2CHK=(nn,ll)                                           +
  | +---------------------------------------------------------+
  
  | where:
  |  nn
  |    Specifies the maximum number of T2 records (whose length
  |    is more than the specified length of second parameter in
  |    T2CHK=) that are ignored (suppressed) and not considered
  |    to be errors. If the number of generated T2 records
  |    exceeds the threshold value, all T2 records are considered
  |    to be errors.
  
  |    The maximum value is 99 and the minimum value is 0.
  |    The default value is 0.
  
  |    This option is effective only for HISAM, HDAM, HIDAM,
  |    PHDAM, or PHIDAM databases.
  
  |  ll
  |    Specifies the maximum length of the T2 which is not
  |    considered to be an error.
  
  |    The maximum value is 99, and the minimum value is 1.
  |    The default value is 7.
  
  |    This option is effective only for HDAM and HIDAM databases.
  |    The value specified for the HISAM database does not cause
  |    an error, but is ineffective.
  
  | For example: T2CHK=(,3) is equivalent to T2CHK=(0,3).
  | T2CHK=(10,) is equivalent to T2CHK=(10,7). T2CHK=(10) is
  | equivalent to T2CHK=(10,7).
  
  | This keyword can be used in the following control statements:
  |     GLOBAL, GROUP, IC, AIC, CIC, ACIC
  
  | This keyword can be defined in site default table.
