Method Detail

preloadResourceTask

public static void preloadResourceTask()
                                throws IOException

INITTASK to preload classes from the resource specified in PreloadPrms.resourceFile.

Throws:

IOException

cycleConnectionOnceTask

public static void cycleConnectionOnceTask()
                                    throws com.gemstone.gemfire.cache.CacheException

TASK to cycle the connection on a distributed system, once only.

Set ConnectionPrms.createCacheAndRegion true to create a cache and region once connected. Set ConnectionPrms.useCacheXml true to create the cache and region using generated XML instead of APIs.

Set ConnectionPrms.bounceVm true to bounce the VM after disconnect.

Set ConnectionPrms.logTimes true to log info-level messages with the duration of various operations.

Set ConnectionPrms.deleteSystemFiles true to delete the system files, and directory if the VM is being bounced, for each connection cycle, to prevent I-node depletion.

Sidesteps the distcache framework and goes to great pains to avoid logging overhead through minimal use of helper classes. Cannot be used with most task methods in CachePerfClient.

Writes statistics values for TaskSyncBlackboard.ops and TaskSyncBlackboard.opTime needed by a separate VM running the CachePerfClient.statArchiverTask(). This is necessary since the statarchiver for the VM executing this task does not live long enough to record stats.

Throws:

com.gemstone.gemfire.cache.CacheException
