Table 7-6. TWORK PARAM Specifications (Page 1 of 2)
Parameter/Default Definition
MAXSEND
Default = 4000
Maximum = 10000
Maximum number of bytes that can be sent to a TRECV in a
single message. For a particular network operation, the
maximum number of bytes that can be sent in a single
message is the lowest value of either this parameter or the
MAXREQUEST PARAM specification for the remote TRECV
server class. Setting this parameter to less than 2072 can
cause failure of network operations involving long data
records.
MAXNOWAIT
Default = 3
Must be 1 through 15
Maximum number of messages that a TWORK can have
outstanding to a TRECV before having to wait for a
response. For a particular network operation, a TWORK
opens a remote TRECV with a nowait depth that is the
lowest value of the following: this parameter, the
MAXNOWAIT PARAM specification for the remote TRECV
server class, or 15. The value is never less than 1.
NETTIMEOUT
Default = 300
Minimum = 300
Number of seconds to wait for network input and output.
ITEMIDCACHE
Default = 20
Number of IDs reserved by the server. Increase this number
if your system creates a large number of items. A TMF
transaction and an update are performed after
itemidcache number of items have been created..
IDLESESSIONDELAY
Default = 24
The number of hours a session must be idle before
TRANSFER terminates the session. Refer to the TSCHED
parameter CHECKSESSIONHOUR. Values less than 24 are
not useful because the check occurs only once a day.
See “Idle Sessions” in Section 11,“Managing a TRANSFER
System,” for a discussion of this parameter.
LOGRECSPEROPEN
Default = 10000
Number of lines written to the log file after which the file is
closed and reopened.
ITEMDELETEDELTA
Default = 24
Minimum = 0 (specifies 1 second)
Amount of time in hours after the end of an item’s delivery
window that TRANSFER waits before deleting an item from
the database. The suggested value is 12: the items will be
deleted 12 hours from the end of the delivery window, which
in most cases is at night, when the TRANSFER system is
less busy.
