近日，本人由于工作需要，需要在redflag linux DC Server 5.0下安装配置weblogic 8.14下的应用，但出现很多问题，现将问题描述及解决方案简述如下：
操作系统：redflag DC Server 5.0
应用平台：weblogic 8.1.4
JDK版本： JDK1.42_04 Jrockit81sp5_142_05
问题描述：操作系统安装正常、weblogic 814安装正常，使用/bea/weblogic81/common/bin/config.sh配置新域，使用jrockit81sp5_142_05的JDK，成功配置完成。但未配置应用前尝试启动startWebLogic.sh系统报错，错误日志如下：

===== END DUMP ============
./startWebLogic.sh: line 66: 5236 已放弃 (core dumped) ${JAVA_HOME}/bin/java ${JAVA_VM} ${MEM_ARGS} ${JAVA_OPTIONS} -Dweblogic.Name=${SERVER_NAME} -Dweblogic.ProductionModeEnabled=${PRODUCTION_MODE} -Djava.security.policy="${WL_HOME}/server/lib/weblogic.policy" weblogic.Server
后更换/bea/jdk142_05为默认jdk，系统可以正常启动，本以为这样就可以正常了，但一天后，Weblogic频繁挂掉，最短时间只有2分钟左右就需要重新启动应用，仍然报错。
出现问题以后，我们立即请求bea电话支持，并发送错误报告给bea，但回应不明确，提供几种方案仅供参考：
一、操作系统问题，可能有某些参数配置不对；
二、更换weblogic版本；
三、更换更新版本的JDK；
四、Weblogic安装有问题，尝试重新安装。
经过多次尝试，发现weblogic 815可以在该环境下正常安装、配置域、使用Jrockit启动startWebLogich.sh，由于weblogic各版本差距较大，因而应用开发平台应与使用平台相同，所以更换weblogic版本可行性较小。
后尝试下载较新版本JDK，我们下载安装的是j2re_1_4_2_08_linux-i586.bin，该文件可在www.java.com下载到，安装以后，问题消失。
总结问题原因，很有可能是weblogic 814与redflag DC Server 5.0包含的jdk存在兼容性问题，因此不能正常启动。
