Cache-Wide Parameters
The cache-wide parameter settings for a distributed cache are maintained on the Terracotta Server Array and affect all of the Integration Servers that use the cache. When you change a cache-wide parameter setting on one Integration Server, the change is applied to all Integration Servers that use the cache.
The following table identifies the cache-wide parameters and indicates whether they affect the cache on the Terracotta Server Array, the local portion of the cache on the Integration Servers, or both. As noted in the table, all cache-wide parameter settings are dynamic, meaning that changes you make to them take effect immediately. You do not need to reinitialize the cache manager or restart the Terracotta Server Array to put the changes into effect.
