我们将在UNIX服务器上运行Java应用程序。要在前台运行它，我们使用下面的代码并将其放在文件
中#! /bin/ksh
/usr/java14_64/bin/java -classpath
/clocal/mptsgrp/user/mptsuser/configcfa/classes:/clocal/mptsgrp/user/mptsuser/configcfa/mqjavalib/xerces.jar::$CLASSPATH
-Djava.library.path=/usr/lpp/mqm/lib:/clocal/udb/db2inst1/sqllib/java/sqlj.zip:/clocal/udb/db2inst1/sqllib/java/db2qgjava.jar:/clocal/udb/db2inst1/sqllib/java/Common.jar:/clocal/udb/db2inst1/sqllib/java/db2umplugin.jar:/clocal/udb/db2inst1/sqllib/java/db2policy.jar:/clocal/udb/db2inst1/sqllib/java/db2dbgm.jar:/clocal/udb/db2inst1/sqllib/java/db2jcc_license_cu.jar:/clocal/udb/db2inst1/sqllib/java/db2jcc_javax.jar:/clocal/udb/db2inst1/sqllib/java/db2java.zip:/clocal/udb/db2inst1/sqllib/java/db2jcc.jar:/usr/mqm/java/lib:/clocal/udb/db2inst1/sqllib/lib:/clocal/mptsgrp/user/mptsuser/mqjavalib:/clocal/mptsgrp/user/mptsuser/mqjavalib/com.ibm.mq.jar:/clocal/mptsgrp/user/mptsuser/mqjavalib/com.ibm.mqbind.jar:/clocal/mptsgrp/user/mptsuser/mqjavalib/com.ibm.mqjms.jar:/clocal/mptsgrp/user/mptsuser/mqjavalib/jms.jar:/clocal/mptsgrp/user/mptsuser/mqjavalib

要从后台运行，我们使用下面的代码并将其放在文件中：
#! /bin/ksh
nohup /usr/java14_64/bin/java -classpath
/clocal/mptsgrp/user/mptsuser/configcfa/classes:/clocal/mptsgrp/user/mptsuser/configcfa/mqjavalib/xerces.jar::$CLASSPATH
-Djava.library.path=/usr/lpp/mqm/lib:/clocal/udb/db2inst1/sqllib/java/sqlj.zip:/clocal/udb/db2inst1/sqllib/java/db2qgjava.jar:/clocal/udb/db2inst1/sqllib/java/Common.jar:/clocal/udb/db2inst1/sqllib/java/db2umplugin.jar:/clocal/udb/db2inst1/sqllib/java/db2policy.jar:/clocal/udb/db2inst1/sqllib/java/db2dbgm.jar:/clocal/udb/db2inst1/sqllib/java/db2jcc_license_cu.jar:/clocal/udb/db2inst1/sqllib/java/db2jcc_javax.jar:/clocal/udb/db2inst1/sqllib/java/db2java.zip:/clocal/udb/db2inst1/sqllib/java/db2jcc.jar:/usr/mqm/java/lib:/clocal/udb/db2inst1/sqllib/lib:/clocal/mptsgrp/user/mptsuser/mqjavalib:/clocal/mptsgrp/user/mptsuser/mqjavalib/com.ibm.mq.jar:/clocal/mptsgrp/user/mptsuser/mqjavalib/com.ibm.mqbind.jar:/clocal/mptsgrp/user/mptsuser/mqjavalib/com.ibm.mqjms.jar:/clocal/mptsgrp/user/mptsuser/mqjavalib/jms.jar:/clocal/mptsgrp/user/mptsuser/mqjavalib

在我们的应用程序中，我们不确定，但与前台进程相比，处理数据时后台进程看起来要慢20-30％。我们将把大量信息写入日志。
