我在DB2中创建了一个数据库。它一直工作到昨天，但现在我在尝试连接数据库时收到以下错误：
[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？如何解决？

这可能是许可证问题。尝试重新安装许可证（如果有）。
