Janus Web Server

Introduced

Before Sirius Mods 6.5

Description

The WEBOPT parameter is a standard Model 204 bitmask-type parameter introduced in Sirius Mods version 6.5. The X'01' setting causes RACF calls to be performed in a special RACF subtask.

In cases where Janus Web Server is deployed and RACF handles login validation, the RACF call load for login-protected web pages can get very high. Since these calls often involve synchronous I/Os that stop the Model 204 main task, they are generally not very good for Model 204 performance. However, if you set the WEBOPT system parameter to X'01', these calls are done in a subtask, reducing their impact on Online performance dramatically.
