Cache statistics methods may return nil for first remote session on a node
When the first session on a remote host logs in, it starts up a shared
page cache on that remote node. Cache statistics for that session are
tracked in that remove SPC.
For the first session on the remote host, certain methods to programmatically
get the cache statistics incorrectly return nil for that session. These
methods are:
System class >> gemCacheStatisticsForSessionId:
System class >> cacheStatisticsForSessionId: (deprecated)
Nil is returned for these sessions from this session and from other session
that subsequently log in using that cache.
Workaround
Other methods to fetch cache statistics work correctly. There are a number
of options depending on what your specific needs are.
To get statistics for the current session, use System myCacheStatistics.
