Command View XP AE Device Manager Server Properties 117
7-2-6 server.http.request.timeout
This property sets the read-blocking timeout of the HTTP socket connection (in milliseconds). It can
be used to enable or disable the SO_TIMEOUT setting for client-connection sockets. Reading from
the input stream associated with a socket will block for only this amount of time before the socket
expires. Its default value is 5000 (5 seconds). A value of zero is interpreted as an infinite timeout,
meaning that SO_TIMEOUT is disabled for client connections. This setting should only be changed by
expert system administrators who want to fine-tune the server’s performance.
Default: 5000 (5 seconds)
7-2-7 server.http.connection.priority
This property sets the priority for all client-connection threads spawned by HTTP requests made
against the Device Manager server. Valid values are between 1 and 10 (1 = minimum priority; 5 =
normal priority; 10 = maximum priority). You should only modify this property if you are an expert
System Administrator seeking to fine-tune the server’s performance. Recommended values are
between 5 and 8.
NOTE: If the connection thread priority is set to 10 (maximum), any simultaneous request connections are
queued for sequential processing, which defeats the purpose of a multi-threaded server. This setting would
actually adversely affect server performance, particularly when you are loading complex HTML pages (for
example, those containing many images).
Default: 7
7-2-8 server.http.connection.bufSize
This property sets the size (in bytes) for all of the server’s input/output (I/O) buffers. Increased buffer
size may improve request/response network performance for high-volume connections, while
decreasing it can help reduce the backlog of incoming data. Do not set the default value smaller than
1024 bytes, or it can cause failure. You should only modify this property if you are an expert System
Administrator seeking to fine-tune the server’s performance.
Default: 8192 bytes
7-2-9 server.http.socket.backlog
This property assigns the maximum queue length for incoming connection indications (a request to
connect), such as setting the SO_MAX_CONN attribute of the server socket. If a connection indication
arrives when the queue is already full, the Device Manager server will refuse the new connection. You
should only modify this property if you are an expert System Administrator seeking to fine-tune the
server’s performance.
Default: 50
7-2-10 server.http.socket.maxThreads
When a request has been issued and is being processed on the Device Manager server, a client has
an active connection on the server. This property specifies the number of active requests that can be
processed at one time on the Device Manager server, not the maximum number of clients. Once this
limit is reached, the next request will be dropped. You should only modify this property if you are an
expert System Administrator seeking to fine-tune the server’s performance.
Default: 50
