SORTMERGESTART Procedure
Table 5-4. SORTMERGESTART flags Parameter Bits (page1of2)
Flag Meaning
flags
Bit Value Description
No purge of
existing output
file
<5> 0 SORTPROG purges an existing output file that seems
too small. This value is the default.
1 SORTPROG does not purge an existing output file that
seems too small, unless the file has the wrong file type
or maximum record length.
Structure for
NEWPROCESS
parameters
<6> 0 SORTPROG uses the process-start four-word
structure described in Table 5-2
on page 5-28. This
value is the default.
1 SORTPROG uses the expanded process-start
structure (an array of one or more 29-word entries)
shown in Table 5-2
on page 5-28. This value is
required for parallel sort or merge runs.
MINSPACE
mode
<7> 0 SORTPROG does not use MINSPACE mode. If the
MINTIME flag is set to 0 and process-start does not
specify a segment size, SORTPROG uses the
AUTOMATIC mode, in which the extended memory
segment size is limited to 50% (90% for the distributor-
collector in parallel sorting) of the available physical
memory. This value is the default.
1 SORTPROG uses MINSPACE mode, in which the
extended memory segment size is 256 pages.
MINTIME mode <8> 0 SORTPROG does not use MINTIME mode. If the
MINSPACE flag is set to 0 and process-start does
not specify a segment size, SORTPROG uses the
AUTOMATIC mode, in which the extended memory
segment size is limited to 50% (90% for the distributor-
collector in parallel sorting) of the available physical
memory, up to 127.5 MB. The default is 56 MB.
1 SORTPROG uses MINTIME mode, in which the
extended memory segment size is limited to 70
percent of the available physical memory.
Scratch file size
check
<9> 0 Exists only for compatibility with earlier versions of
FastSort.
1 Exists only for compatibility with earlier versions of
FastSort.
Alternate
collating
sequence table
<10> 0 SORTPROG ignores the collate-sequence-table
parameter. This value is the default.
1 SORTPROG uses the alternate collating sequence
table. If you did not provide the table,
SORTMERGESTART returns error 67.
