Receiving a File 57
This data can be scanned for string matches. The extended compression window size affects how
much virtual memory the extended compression routines use. Higher window size values use more
memory but achieve greater compression. The valid values for this subparameter are 8–15, inclusive.
The default value is *INITPARMS.
ECMLEVEL specifies the extended compression memory level parameter, which determines how
much memory should be allocated for other internal data structures like the hash table and the
previous table (pointers to previous strings starting with the same 3 characters). The extended memory
level affects how much memory the extended compression routines use. Higher memory levels use
more virtual memory but achieve greater compression. The valid values for this subparameter are 1–9.
inclusive. The default value is *INITPARMS.
EXCLUDE(generic, member-name, (start-range/stop-range), ‘list’)
specifies criteria that identifies the file members that are not to be copied. EXCLUDE allows you to
make exceptions to members specified generically or by range in the SELECT option. Refer to the
IBM Sterling Connect:Direct Processes Web site at
http://www.sterlingcommerce.com/documentation/processes/processhome.html
for the syntax and
override priority for the SELECT and EXCLUDE parameters appropriate to the remote node.
generic specifies a generic member name. For example, if you specify CD*, all member names
beginning with CD are excluded.
member-name specifies an individual member name.
start-range/stop-range specifies first and last names in an alphanumeric range of members.
Although member names in a range are treated as generics, they cannot be used with an asterisk (*). A
slash (/) separates the first (start-range) and last (stop-range) member names. The two members
specified, as well as all members in the range, are excluded.
‘list’ specifies any combination of the subparameters.
FALIAS(*YES
|*NO)
specifies whether aliases are copied when their associated member names are copied.
FBUFND(n)
specifies the number of I/O buffers VSAM uses for transmitting data between virtual and auxiliary
storage. (A buffer is the size of a control interval in the data component.) Valid values range from
1–510. The default is 2. Increasing this number generally improves the I/O performance on the file but
requires more memory. This parameter is valid only when the source side is an z/OS node.
FDBPARMS(dbid, dbsubid)
indicates that the Sterling Connect:Direct for z/OS SQL SERVER is to process the I/O request against
the database identified by the subparameters of this keyword and defined by the SQL= parameter. The
DBPARMS parameter is used with the optional Sterling Connect:Direct for SQL feature. This
parameter is valid only when the source side is a z/OS node. Only DB2 is supported.
To determine the values to code to access a given DB2 table or set of DB2 tables, consult your
database administrator.
dbid specifies the 1–4 byte DB2 database ID.
dbsubid specifies the 1–4 byte DB2 database sub-ID.
FDCB(modeldcb, blksize, den, dsorg, keylen, linct, lrecl, optcd, recfm, rkp, trtch)
overrides attributes of the source file. DCB attributes are determined from the operating system unless
specified.
modeldcb specifies a model data set control block (DSCB).
blksize specifies the length in bytes of the block. The minimum length is 18 bytes, and the maximum
length is 32,760 bytes.
