问题

当所有 OCI 服务均已启动时，可能会出现以下一个或多个症状：

1. 尝试访问 OCI 时， Web 浏览器中显示 404 错误。

2. Elasticsearch （ ES ）会一直超时，并且没有节点可供使用。要进行检查，在https://locahost/cat/healthhttps://localhost/cat/indices OCI 服务器中输入和（在 Web 浏览器中）时，此网页将：

尝试加载，然后最终超时
在 0% 处显示黄色或红色。

3. Elasticsearch 将无法响应任何请求，如以下日志中所示：

oci-cluster.log （位于<installed_path>\SANscreen\program_data\elasticsearch\logs）显示了所有超时请求以及无法删除索引的情况。

server-indexer.log （位于）<installed_path>\SANscreen\wildfly\standalone\log将显示由于更新期间的版本冲突而导致的增量索引器失败。这意味着在计划的扫描之间会发生多个更新。此外，还存在一些错误，表示无法更新别名。

事件队列容量几乎已接近，即 2000 年<installed_path>\SANsceen\wildfly\standalone\log中超过了 1950 ，如 events.log （位于）所示。此外，还可以同时观察到大量标注和应用程序更新事件。
