红帽全球峰会2.4. 主机系统和依赖项问题
在某些情况下，Data Grid 部署可能会遇到主机系统或外部依赖项导致的错误。本节详细介绍了任何已知问题，以及故障排除和临时解决方案。
Red Hat Enterprise Linux 7 上的 TLS
RHEL 7 提供 OpenSSL 库的版本，它尚不提供对 TLSv1.3 的支持。但是，Data Grid Server 8.3 默认启用 TLSv1.3 和 TLSv1.2，这会导致加密 Hot Rod 和 REST 端点的客户端连接出现错误。
Data Grid Server 还记录如下信息：
WARN [org.infinispan.HOTROD] ISPN004098: Closing connection due to transport error org.infinispan.client.hotrod.exceptions.TransportException:: ISPN004077: Closing channel due to error in unknown operation.
WARN [org.infinispan.HOTROD] ISPN004098: Closing connection due to transport error
org.infinispan.client.hotrod.exceptions.TransportException:: ISPN004077:
Closing channel due to error in unknown operation.如果您在 RHEL 7 上安装 Data Grid Server，您应该使用以下 JVM 选项禁用 OpenSSL 来使用原生 Java SSL 库：
-Dorg.infinispan.openssl=false
-Dorg.infinispan.openssl=false
