开滦项目性能调优总结

1、开滦项目性能调优总结调整前数据库服务器telnet 至数据库服务器查看资源占用（2台数据库集群）通过资源占用可以看出：当前数据库服务器的CPU（16颗）有瞬时的等待，整体在80%区间内，运行正常。页交换方面是0，没有页交换出现。内存方面，2这台数据库服务器可用内存为：1.9G左右，10.20.10.11这台在0.8G左右。Oracle当前参数配置SQL show parameterNAME TYPE VALUE O7_DICTIONARY_ACCESSIBILITY boolean FALSEactive_instance_count integer aq_tm_processes integ
