一个监控java程序运行的shell
#!/bin/sh exportJ_LIB=/data/sms/lib; exportCLASSPATH=.:$J_LIB/jtds-1.2.jar:$J_LIB/log4j-1.2.12.jar:$J_LIB/postgresql-8.1-404.jdbc3.jar; exportJAVA_HOME=/usr/java/jdk1.5.0_05 exportJRE=/usr/local/jdk/jre exportSHELL=/bin/bash exportHOME=/data/sms #javacheckstatus if/bin/psax|/bin/grep-vgrep|/bin/grep"javaXinTai";then cd; else cd/data/sms/xintai; /usr/java/jdk1.5.0_05/bin/javaXinTai>/dev/null& fi
定时执行可以保证javaXinTai可以一直在运行
