我已经在DB2中创建了一个数据库。直到昨天它还在工作，但现在我在尝试连接到数据库时得到以下错误:
[IBM][CLI Driver] SQL1031N The database directory cannot be
found on the indicated file system. SQLSTATE=58031
Explanation:
The system database directory or local database directory could not be
found. A database has not been created or it was not cataloged
correctly.
The command cannot be processed.
User response:
Verify that the database is created with the correct path specification.
The Catalog Database command has a path parameter which specifies the
directory where the database resides.
sqlcode: -1031
sqlstate: 58031
错误的原因是什么，我如何修复它?
查看实际数据库文件所在的数据库文件夹是否已重命名或移动。
可能是许可证问题。尝试重新安装许可证
