java - COBOL 与服务器的连接在 VSCode 中关闭

Question

我现在正在尝试学习 COBOL(希望)能够帮助解决危机。我正在调用IBM course这需要 VSCode 中的“IBM Zowe Open Editor”和“Zowe Explorer”扩展。我花了很长时间为其设置 JDK。我使用 JDK1.8.0_251，如 configuration问道。我仍然收到错误消息“cobol 语言服务器在过去 3 分钟内崩溃了 5 次”，导致我的代码无法运行。以下是 COBOL 语言服务器的输出:

更新:我想我需要访问 z/OS 大型机。我找到了如何获得免费访问here在 IBM 的 Master the Mainframe 计划中，但显然我需要添加 z/OSMF 软件(只为您提供 3 天的免费试用期)或名为 Remote System Explorer API 的东西。我会继续研究...

Answer 1

报告中数据中心升级时 COBOL 服务器系统不可用。 COBOL 服务器现已启动。我建议使用开放大型机项目、OMP、slack channel cobol 编程类(class)来寻求帮助。仅供引用 - z/OSMF 已安装并可运行。 COBOL 类(class)系统、Master the Mainframe 学习系统、Zowe 教程系统和 ZTrial 系统都是具有单独 IP 地址的独立 z/OS。请包含系统的 ID 和 IP 地址，以确保我们保持同步。
