我们最近使用2个tomcat节点（7.0.53）对我们的应用程序进行了集群，并根据Tomcat文档设置了集群https://tomcat.apache.org/tomcat-7.0-doc/cluster-howto.html
一切都按预期工作，除了会话复制在故障转移时不起作用，我必须在两个tomcat实例上设置The output should be like
DOUBLE COUNT
01 02 10 (as example)
03 04 12 (as example)
I am getting duplicated like...
01 02 10 (as example)
01 02 10 (as example)
<?php
if ($check == 'doubles'){
sort($doubles);
foreach ($doubles as $double) {
explode(" ", $double);
$dn1 = $double[0].$double[1];
$dn2 = $double[2].$double[3];
if ($stmt = $post_con->prepare('SELECT DISTINCT FROM tb WHERE CONCAT(" ", res, " ") LIKE CONCAT("% ", ?, " %") AND CONCAT(" ", res, " ") LIKE CONCAT("% ", ?, " %")')) {
$stmt->bind_param("ss", $dn1, $dn2);
$dn1 = sprintf('%02d', $dn1);
$dn2 = sprintf('%02d', $dn2);
$stmt->execute();
$stmt->store_result();
$qty = $stmt->num_rows;
echo '<div class="mini">'.$dn1.'</div>';
echo '<div class="mini">'.$dn2.'</div>';
echo '<div class="n-sort">'.$qty.'</div>';
}
}
?>
以使会话复制工作。我提到hazelcast文档来设置http://docs.hazelcast.org/docs/3.5/manual/html/websessionreplication.html，会话复制在tomcat失败时完美运行。我只是想知道这是Tomcat会话复制的一个错误吗？或者是否必须使用hazelcast等第三方库来实现tomcat失败的会话复制？
