To improve WebUI response time, an administrator can adjust the frequency at which the WebUI queries the database for new information. The WebUIAppEnvDATAREFRESHSECONDS setting controls the overall interval for refreshing WebUI data. The WebUIAppEnvCACHETTL (Time To Live) setting specifically defines how long data remains valid in the cache before it is considered stale and needs to be refreshed. Increasing the values for these settings reduces the load on the database and server, which can improve the perceived performance and responsiveness of the WebUI at the cost of data freshness.

A. WebUIAppEnvSPQUEUECONCURRENT: This setting manages the number of concurrent stored procedure calls to the database, affecting throughput, not the cache refresh interval.

C. WebUIAppEnvCACHEINTERVAL: This is not a valid or recognized advanced setting for the HCL BigFix WebUI.

D. WebUIAppEnvSITECACHESIZE: This setting controls the maximum number of sites to be held in the cache, which relates to the size of the cache, not its refresh timing.

Details: This document explicitly lists and describes WebUIAppEnvDATAREFRESHSECONDS as "The interval

in seconds

at which the WebUI data is refreshed" and WebUIAppEnvCACHETTL as "The time to live

in seconds

for the WebUI cache." It also defines WebUIAppEnvSPQUEUECONCURRENT and WebUIAppEnvSITECACHESIZE

confirming their purposes are unrelated to cache refresh intervals. The setting WebUIAppEnvCACHEINTERVAL is not present

confirming it is not a valid option.
