Since there are only 10 samples (by default) in a hour, if it gets unlucky a few times you will get an out of memory alert when there is nothing to be worried about.I boosted the samples to 120/hour, so it gets a better picture of the amount of heap that is free on average. Now that a few bad samples can39。修改Thread Count的值,然后重啟WebLogic就可以生效了。l :set JAVA_HOME=d:\bea\jrockit81sp1_141_03set JAVA_VM=jrockitset MEM_ARGS=Xms512m Xmx1000ml
