Situation
This TID explains how to enable cache for "Child Availability" calculation in SLA Availabilty status portlet of Business Service Dashboard. This configuration will only affect "Viewable Elements" mode of the portlet.
Resolution
Create Formula.custom.properties in ~ManagedObjects/config directory if it doesn't exist
Add the following lines to the file:
# To be used by Availability status report-->Viewable Elements-->child availability/downtime selection
# These settings will enable cache and speed things up from portal side results
PortalBuilder.useCache=true
# These settings will enable cache and speed things up from portal side results
PortalBuilder.useCache=true
# Value in minutes.
PortalBuilder.cacheTimeout=2
PortalBuilder.cacheTimeout=2
# Value in hours.
PortalBuilder.cacheAgeOut=24
PortalBuilder.cacheAgeOut=24
Additional Information
cacheTimeout is the refresh period for the cache. In other words portal will fetch the new contents after this period of time.
cacheAgeOut indicates the time for cache expiration. If the cached contents are not accessed for the time specified by cacheAgeOut then they cache will be cleared away.
