Configuration for Distributed Server Architecture
PlantScape Server and Client Configuration Guide 355
The maximum tuning settings for each remote server are set by the global cache
age time. The cache flush time is calculated first. The cache flush time is then
used to calculate the cache age time. The cache age time is then used to calculate
the maximum subscription time. These calculations are as follows:
To tune the global cache settings:
1
On the System Configuration Menu display click Distributed Servers. The
Distributed Servers Configuration summary opens.
2
Click the link flagged as This Server. The Distributed Server Local
Configuration display opens.
3
Click the Tuning tab.
You can tune the following global cache settings to apply to all distributed
architecture connections on the subscribing server.
Tuning Setting Minimum Value Maximum Value
Cache Flush Time 10000ms. (Global Cache Age Time)/4
Cache Age Time Cache flush time Global Cache Age Time - (2 * Cache Flush
Time)

Property Description
Cache Age Time Sets the maximum limits (in milliseconds) for the tuning
settings for each remote server this server will access.
The default is 1 hour. (Also referred to as global cache
age time.)
Read Data Valid Time The amount of time (in milliseconds) that data remains
valid. When this time expires, the values are read again
from the publishing server. This value is independent of
the subscription time. The default value is 10 seconds.
