Center, are installed. Refer to that network product’s
documentation to obtain the appropriate server names.
minservers The minimum number of servers which will be in
existence at all times. This includes active and reserved
servers. These servers are created immediately on the
initiation of Network Services and are then kept in
reserve until a change request is received. Once the
change request is completed, the server is returned to
reserve status. If necessary, additional servers are
created immediately to fit the new minimum specified.
Valid range: 0–1250; however, see the following note.
Default: 0
maxservers The maximum number of servers. If necessary, reserved
servers will be terminated to fit the new maximum.
However, a server that is in use will not be terminated
until it is returned to the reserved server pool.
Limits in the number of allowed processes and internal
data structures can prevent you from reaching the
maximum number of servers. Valid range: 0–32767;
however, see the following note.
Default: Varies by server
NOTE
The total number of all active servers may not exceed 1250. The sum of
all minservers must always be 1250 or less. You may specify a number
greater than 1250 as one or more maxservers values, but there will
never be more than a total of 1250 servers of all kinds at any one time.
Discussion
The number of server processes is controlled with the SERVER function.
The maximum number of servers limits how many processes of each
server type can be in existence at any time. If the servers are at the
maximum limit and a new change request (such as a DSCOPY or REMOTE
HELLO) is received, the request will be rejected. By setting a maximum
limit, you can control the amount of process resources available for
NS 3000/iX.
Because the creation and initialization of a server takes time, using
reserved servers decreases the set up time for a change request. A
reserved server is created ahead of time and is held in reserve until a
change request is received. The minimum number of servers controls
the number of reserved processes for each type of server. The number
set for the minimum does not limit the number of concurrent users of
the Network Services. If there are more concurrent users than the
minimum number of servers specified, new users can use the Network
Services, but there is a delay while the additional servers are created.
