ABSTRACT OF PROBLEM
___________________
Unlimited Pool Segment Support.
COMMENTS ON PROBLEM
___________________
Unlimited pool segment support was designed to address the fol-
lowing major issues associated with the online RECOUP package:
o Pool Segment Restrictions: The long-term directory refer-
ence table (LTDRT) is a file resident record and, therefore,
limited to a size of 4096 (4K) bytes. As a result, section
2 of the LTDRT can only describe pool directories that cor-
respond to a maximum of 125 pool segments defined in a TPF
system. Further, RECOUP procedures require assembling pool
segment information into program segment DYD0. Since DYD0
is also limited to 4K bytes in size, a maximum of 190 pool
segments can be defined in it. Customers require the
ability to define more than 125, even 190, pool segments in
their TPF system.
o Performance Restrictions: RECOUP and PDU processing sequen-
tially search the LTDRT to find the bit in a specific pool
directory that represents a specific file address. As the
number of pool segments defined in the TPF system grows
larger, the search time for a sequential record search can
grow prohibitively large. A faster, more efficient search
method is required.
o Extensive Pool Generation and Reallocation Procedures:
Program segment DYD0 must be manually rebuilt to include
online pool maintenance available (OPMAAA) and/or online
pool maintenance deactivation (OPMBBB) records. An improved
method of creating OPMAAA and/or OPMBBB records is required.
SOLUTION
________
The following changes have been made as a part of unlimited pool
segment support:
o Eliminating Pool Segment Restrictions: Unlimited pool
segment support eliminates pool segment restrictions by
eliminating section 2 of the LTDRT and assembled pool
section information from program segment DYD0. Section 2 of
the LTDRT has been replaced by the IBM pool allocation
resource table (IPART), which resides in main storage only.
The ZPOOL GENERATION CREATE functional message processing no
longer uses DYD0 to extract pool segment information. This
information is now retrieved directly from the FACE table
(FCTB).
o Improved Performance During RECOUP and PDU Processing:
Unlimited pool segment support replaces section 2 of the
LTDRT with the IPART, which resides in main storage, and
uses a combination index and b-tree search mechanism for
quicker searches to improve RECOUP and PDU processing per-
formance.
o Improve Pool Generation and Reallocation Procedures: After
creating and loading a new FACE table to the TPF system,
pool generation and pool reallocation will automatically
create pool segment information. Internal processing calls
to the RTCUC macro with the POOLSEGMENT parameter specified
returns data similar to what existed in the OPMAAA table.
Additionally, internal processing calls to the RTCUC macro
with the DEACTIVATEDSEGMENT parameter specified returns data
similar to what existed in the OPMBBB table.
