Server Configuration Options
Property Description
Maximum servers
Maximum number of copies of a server process that can run in a server pool at the
same time. The range of values is 0 through 4095.
Static servers
Number of static servers, which are processes that are started automatically when
the TS/MP environment starts. (Dynamic servers are started as needed by the
PATHMON process.) The range of values is 0 through 4095. The value must not
exceed the value of the Maximum servers field. For OTS, it is recommended to
configure the Static servers field to be equal to Maximum servers, because using
dynamic servers can lead to aborted transactions under some circumstances.
Setting the number of static servers close to or equal to the value for Maximum
servers also enhances performance.
Process name
Name of the server process. If you do not choose a name, the system assigns one
when the process starts.
Processors
List of CPUs in which server processes can run. Separate the CPU numbers with
commas; for example, 1,2,5. If you do not specify a list of CPUs, the system runs
server processes in any available CPU. Specifying certain CPUs requires the
system to use only the CPUs in the list.
Process priority
Priority at which the server process is run. The range of values is 1 through 199,
the highest priority being 199.
Autorestart attempts
Number of attempts to restart the server process, in the event of its abnormal
termination. The maximum number is 32767.
Create delay
Length of time in microseconds requests are queued while a LINKMON process
waits for a server (static or dynamic) to become available. When this time period is
exceeded, the PATHMON process creates a dynamic server to process requests.
The maximum time is 18 hours.
Delete delay
Length of time in microseconds the PATHMON process waits before deleting
unused dynamic server processes. The maximum time is 18 hours.
Max links
Maximum number of links that a server process in a server pool can have to all
LINKMON processes on the host system. For example, if the Link depth field is
set to 10 and there are 3 CPUs in the host system, set the Max links field to 30 to
avoid queueing requests at the server process. While a server process is processing
a request, the maximum number of queued requests is the value of the Max links
field minus 1. The range of Max links values is 0 through 4095.
Link depth
Number of concurrent links allowed from a LINKMON process to a particular
server process in a server pool. The range of values is 1 through 255. Set the value
of Link depth to be less than or equal to the value of Max links. If Max links is 0,
use the default value of 1 for Link depth.
