ABSTRACT OF PROBLEM
___________________
32-Way Loosely Coupled Pool Support.
 

COMMENTS ON PROBLEM
___________________
Currently,  TPF  supports  a  maximum  of  8  processors loosely
coupled in a single TPF complex.  32-Way  Loosely  Coupled  Pool
Support  provides  structural  changes  to pool support to allow
future configurations of up to 32 loosely coupled processors  in
a single TPF complex.
 

SOLUTION
________
Keypoint  9  (CTK9),  the pool section keypoint tables (CY2KTs),
and the short-term  common  control  records  (STCCRs),  contain
tables  based on a maximum of 8 loosely coupled processors.  New
formats have been provided for CTK9, the CY2KTs, and the  STCCRs
to  allow  a  maximum of 32 loosely coupled processors.  Because
the amount of data required for 32 processors  exceeds  the  4-K
limit of CTK9, some of the data previously kept in CTK9 has been
moved  to  fixed  file  records.  To contain CTK9 within the 4-K
limit, the active and standby set size tables and part  of  each
CY2KT have been moved to the new fixed file record type, #CY2KT,
where each ordinal in the #CY2KT fixed file record type contains
one CY2KT data record.
 
In  addition,  the short-term processor control records (STPCRs)
are currently stored in a shared fixed file record type (#STPCR)
that uses ordinal-based uniqueness to provide a  unique  set  of
records  for  up  to  8  processors. To support up to 32 loosely
coupled processors, the STPCR control and data records have been
moved from their shared record type, #STPCR, to a new  processor
unique record type, #STPUR.
 
Finally,  to  facilitate  the  addition of new pool types in the
future, the pool descriptor record  (CYPDR)  has  been  provided
with a new format.
 
To  facilitate  coexistence  and  migration, access methods have
been provided for the affected  pool  data  structures  and  are
similar to those used for the Pool Expansion Project (PXP), APAR
PJ17912.    Each  of the affected data structures (CTK9, CY2KTs,
STCCRs, STPCRs, and CYPDR) has a record  retriever  function  to
find  and  file these records. While the pool data structures on
DASD are in PXP format, the access methods convert  the  records
from  PXP  format  to 32-Way Loosely Coupled Pool Support (32LC)
format before returning the record to the  requesting  function.
Conversely,  the access methods convert the data structures from
32LC format to PXP format before filing the record to DASD. This
allows coexistence with processors that have not been IPLed from
an image containing 32-Way Loosely Coupled Pool  Support.    The
access  methods convert the pool data structures between PXP and
32LC formats as long as the ZPMIG CONVERT functional message has
not been issued and the pool data structures on DASD are in  PXP
format.  Issuing  the  ZPMIG CONVERT functional message converts
all pool data structures on DASD to 32LC format. At that  point,
the  access  methods  are still used, but they no longer convert
the pool data structures between 32LC and PXP formats. All  pool
data structures are used and filed in 32LC format.
 
If  ZPMIG FALLBACK is used to return the pool data structures on
DASD to PXP format, the access methods automatically detect this
and convert the  pool  data  structures  between  32LC  and  PXP
formats.
 
At  this  time,  TPF  is still limited to a maximum of 8 loosely
coupled processors in a TPF complex. Additional functionality is
required before TPF can support a configuration with more than 8
loosely coupled processors.

Migration Considerations
========================
      As follows:
 
  Message changes
  --------------------------------
      Yes
 
  Functional Changes
  ----------------------------------
      The ZPMIG functional message has been changed to convert the
      pool data structures between Pool Expansion Project (PXP)
      format and 32-Way Loosely Coupled Pool Support (32LC) format.
 
      See TPF Migration Guide: Program Update Tapes for more
      information about functional changes.
 
  Automation and Operation Changes
  ----------------------------------
      See TPF Migration Guide: Program Update Tapes for more
      information.
 
  Coexistent Configurations
  -------------------------
      A processor IPLed from an image containing 32-Way Loosely
      Coupled Pool Support can coexist indefinitely in a TPF
      complex with processors that have been IPLed from an image that
      does not contain 32-Way Loosely Coupled Pool Support.
 
      Once the ZPMIG CONVERT functional message is issued, any
      processor joining the complex must be IPLed from an image
      containing 32-Way Loosely Coupled Pool Support.
 
  Recommended Migration Scenario
  ------------------------------
  Follow these guidelines to apply this support to your system.
  See TPF Migration Guide: Program Update Tapes for more information.
 
  1.  Ensure that no deactivation or reallocation processing is
      running on the system.
 
  2.  Install PUT 14, which contains APAR PJ27686 for 32-Way
      Loosely Coupled Pool Support.
 
  3.  Examine your TPF system to determine if you must modify your
      pool migration user exits to accommodate 32-Way Loosely Coupled
      Pool Support. Note that the user exits represented by UPX0, UPX1,
      UPX2, and UPX3 have been reused from the Pool Expansion
      Project (PXP).
 
      Name of           User Exit       Activated
      User Exit:        Program:        In:
      Rearrange_CTK9    UPX0            CYH0
      Dearrange_CTK9    UPX1            CYH1
      Find_STCCR        UPX2            CYH2
      File_STCCR        UPX3            CYH3
      Find_CY2KT        UPX6            CYH6
      File_CY2KT        UPX7            CYH6
 
  4.  Examine your TPF system to determine if your code accesses
      CTK9, CY2KTs, STCCRs, STPCRs, or the CYPDR. Your code must
      be changed to use the appropriate access methods when finding or
      filing any of these pool data structures. See TPF Migration
      Guide: Program Update Tapes for more information about these
      access methods.
 
  5.  Define the new record types in all SIP Stage I decks as follows:
 
      -#CY2CPY:
          Shared record
          Defined in all subsystems
          4K Record
          Requires 48 ordinals
 
      -#CY2KT:
          Shared record
          Defined in all subsystems
          4K Record
          Requires 48 ordinals
 
      -#CY2NEW:
          Shared record
          Defined in all subsystems
          4K Record
          Requires 48 ordinals
 
      -#STPUR:
          Processor unique record type defined for all processors
          Defined in all subsystems
          4K Record
          Each processor requires the following number of ordinals
           to be defined for it:
             12 + ((number of SST-A directories + 499)/500)
                + ((number of LST-A directories + 499)/500)
                + ((number of 4ST-A directories + 499)/500)
                + ((number of SST-B directories + 499)/500)
                              .
                              .
                              .
                + ((number of 4ST-D directories + 499)/500)
             where the calculation in parentheses is repeated 12
             times, once for each short-term pool section.
 
  6.  Run the FACE Table Generator (FCTBG) to create a new FACE table.
 
  7.  Assemble the SIP Stage I deck to create a SIP Stage II deck.
 
  8.  Run SIP Stage II.
 
  9.  Load 32-Way Loosely Coupled Pool Support to an image in your
      complex and re-IPL all active processors using that image.
 
 
4
 
 
 
 
 
 
 
 
 
 
 10.  Once all active processors in the TPF complex have been IPLed
      from an image containing 32-Way Loosely Coupled Pool Support,
      the pool data structures in each subsystem can be converted to
      32LC format. To convert the pool data structures, perform each
      of the following steps once in each subsystem:
 
      a.  Ensure that the pool status is set for each processor by
          entering the ZDFPC functional message on each processor.
 
      b.  Verify that all active processors in the complex are
          running from an image containing 32-Way Loosely Coupled
          Pool Support by issuing the ZPMIG STATUS functional
          message from each active processor. Message PMIG0011I
          should be displayed on the console of each processor. If
          this message is not received, the processor on which the
          ZPMIG functional message was issued was not IPLed from an
          image containing 32-Way Loosely Coupled Pool Support.
          Re-IPL the processor on the correct image before
          proceeding.
 
      c.  Enter the ZPMIG CONVERT functional message to convert all
          pool data structures to 32LC format. This functional
          message may be entered from any active processor in the
          complex.
 
      d.  When you enter the ZPMIG CONVERT functional message and
          there are inactive processors that have never been IPLed
          from an image containing 32-Way Loosely Coupled Pool
          Support, those processors may not have current pool carve
          values set in keypoint B. When the inactive processors are
          brought into the complex, pool restart validates the amount
          of storage carved for pools, if necessary, resetting the pool
          carve values in keypoint B and requesting an IPL. Because
          this validation is performed for a single subsystem at a time,
          a complex with multiple subsystems could see multiple
          requests for IPLs when bringing up the inactive processors.
 
          To avoid these additional IPLs, enter the ZGFSP SET functional
          message on each subsystem for each inactive processor. This
          sets the pool carve values in keypoint B.
 
 11.  Once the pool data structures have been converted to 32LC
      format and there is no need to fall back to PXP format, the
      #STPCR fixed file record type can be removed from the SIP
      Stage I deck. Note that once the #STPCR fixed file record
      type is removed, fallback will no longer be possible.
