基于LGH-PE站点查询了所有站点虚拟机配置发现以下站点虚拟机硬盘设置中cache不等于unsafe
LGH-PEPolicyBroker(10.230.12.2)、NEZHAAgent(10.230.12.3)、Data Transporter(10.230.12.4)
OAP-PEPolicyBroker(10.231.12.2)、NEZHAAgent(10.231.12.3)**yinfutao** commented on *2023-01-10T10:37:43.927+0800*:
通过测试已整理出调整磁盘缓存策略文档,待[~chengsiyuan] 在现场测试环境进行校验。

使用五层工程部测试环境的OLAP再次进行测试把磁盘缓存策略从Default (No cache)调整到Write back (unsafe)后MD5值没有变化OLAP程序正常启动。
登录测试环境的TSG界面下发安全策略的URL阻断、拦截和代理策略的URL阻断、关键字监测、内容替换、URL重定向、下载劫持、脚本注入都能达到对应的效果。[~chengsiyuan]
