WEBSDMAX is a parameter on JANUS DEFINE, which defines and sets characteristics of a Janus port. See the List of JANUS DEFINE parameters.
This parameter indicates the maximum number of sdaemons to be used for cached web logins. This parameter has no effect unless the WEBLOGHOLD parameter is set to something other than 0.
Since there is no upper limit to the number of login requests that can come into a web port at a given instant, it is quite possible for a flurry of login requests to tie up every sdaemon, causing a variety of problems including making it impossible to connect to any Janus port. WEBSDMAX limits the number of sdaemons that will be used by a port for cached logins. If a new cached login is required, and WEBSDMAX will be exceeded, the oldest cached login session will be discarded even if it hasn't been around WEBLOGHOLD seconds.
The default for WEBSDMAX is half the number of sdaemons defined to the Online. If sdaemons are used heavily for other purposes in the Online or there are multiple ports using the logon caching facility, WEBSDMAX should be adjusted down. For more discussion of the logon caching feature, see the Janus Web Server Reference Manual. WEBSM is a synonym for WEBSDMAX.
This parameter is valid only for WEBSERV ports.
