<div id="body1590128863846"><div class="section" id="mrs_01_1019__s1b2ee2c9093c4228adbfc35c6d501e70"><h4 class="sectiontitle">Scenario</h4><p id="mrs_01_1019__a4d86a30ec10043a4b6e3f7efbbb83986">When the number of clusters reaches a certain scale, the default settings of the Java virtual machine (JVM) cannot meet the cluster requirements. In this case, the cluster performance deteriorates or the clusters may be unavailable. Therefore, JVM parameters must be properly configured based on actual service conditions to improve the cluster performance.</p>
