ql
Determines the requested queue length, which controls how many concurrent client connection requests can be handled.
usys$tcp_params {=} ql=Number
Arguments
Number—number of client requests that can be queued. When that queue is full, the client request is rejected and the client has to try again.
Use
Use in the assignment file of the Uniface Router.
Description
The ql option determines the
requested queue length for the TCP listen() function, which is used when creating
a listening socket.
When a number of client requests arrive at the same time on the same listening port, TCP puts them in a queue and handles them sequentially. When that queue is full, it rejects the client request and the client has to try again.
The queue length determines how many concurrent
client connection requests can be handled. By default, the TCP connector uses the maximum queue
length specified by the operating system using the macro SOMAXCONN. Platforms used
to set this to 5, and you could use the ql option to override this value.
Note: In recent years, most vendors have increased the maximum queue to thousands, so you should no longer need to use this setting.
