Object DS Commands

SQL/MX Connectivity Service Administrative Command Reference—526350-005

5-3

ADD DS

existing DS. The existing DS and the new one must have different names. Two

DSs with the same name generate an error.

Using this parameter can be the first step in renaming a DS, followed by stopping

and deleting the old DS.

MaxServer count

is the upper limit on the servers that can be operational for this service on this DS.

The default value is 1. A value of 0 gives the system default, which is a value

determined by the system at run time. Valid values are 0 through the total number

of ports allowed, minus 3. The MXOAS command determines the total number of

ports allowed. Different services can have different limits, which prevents you from

validating them when you create them.

IdleServer count

is the lower limit on the available idle servers that are operational for this service

on this DS. Valid values are 0 through MaxServer count, with 0 as the default.

This count represents idle servers that are waiting for user connections. At DS

startup, once the InitServer count is satisfied, additional servers are started

until the IdleServer count is reached. Initially, idle servers are started in blocks

of five, with a check for incoming connection requests occurring between each

block. After peak user loads, idle servers are terminated to the IdleServer

count value (see IdleTimeout on this page).

InitServer count

is the suggested number of servers that each service starts when the DS first

starts. Legal values are from 0 to the smaller of either 1000 or the value specified

by the MaxServer count, with the default value as 0. If the initial server count

exceeds 1000, an error is displayed. When the value for InitServer count is

greater than 0, the servers are started in blocks of five with a check for incoming

connection requests occurring between each block. To permit servicing incoming

users, the DS goes to the STARTED state as soon as the first server starts. These

servers count as idle if they are not allocated to new users immediately.

IdleTimeout timeout-val

is a keyword or the integer number of minutes a server waits in the available state

for a connection before it stops itself when the count of servers exceeds the

IdleServer count value for the DS. The default value is SYSTEM_DEFAULT,

which is defined by MXCS (ten minutes, currently). Other valid values are

NO_TIMEOUT and from the integer one to a large number.

timeout-val

SYSTEM_DEFAULT | NO_TIMEOUT | minutes

Note. The value of 1000 is applicable from H06.26/J06.15 RVU and SQL/MX version R3.2.1.
