hmchistoryentries表在1808年版本中不存在。

Question

在进行系统更新(或ant更新系统)时，我们会发现错误(hmchistoryentries不存在)。以前有人遇到过这种情况吗？根据文档，这似乎是一种过时的项目类型。虽然我们没有使用hmc，但是我们不确定哪个扩展正在使用这个项目类型。感谢你的帮助。

Answer 1

你能搜索所有*-items.xml文件来找出它的扩展名吗？您还可能希望检查您的localextensions.xml文件是否存在扩展名或任何扩展名(取决于扩展名)。如果它在那里，你可以把它移除。

Answer 2

此错误是由于DB连接器版本不正确造成的。我们使用的是MySQL 8.0和MySQL连接器-java-8.0.19.jar连接器。但SAP官方不支持1808年版的MySQL 8.0。将其降级为MySql 5.x和mysql-连接器-java-5.1.x-bin.jar之后，此错误不再存在。

谢谢。
