WebSphere Application Server V7.0: Concepts ... - IBM Redbooks

The new properties will be listed by default in the system log, although they must
first be created as Custom properties to benefit from them. To do so, log on to the
Integrated Solutions Console and navigate to Server → Server Types →
WebSphere application servers → (your_server) → Server Infrastructure →
Administration → Custom properties → New. This will create the properties
on a server base.
Note: When modifying one of the new parameters listed in Table 14-2 make
sure to have these additional parameters configured (available in prior
versions):
► control_region_timeout_delay
► control_region_timeout_save_last_servant
