我在 DB2 中创建了一个数据库。它一直工作到昨天，但现在尝试连接到数据库时出现以下错误：
[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: …db2-connect ×1
