The -901 error may also occur with the following error message 
returned when user creates a nickname: 
 
SQL0901N  The SQL statement or command failed because of a 
database system 
error. (Reason "invalid index colnames".)  SQLSTATE=58004 
 
This is an error raised when there is a remote table which has 
an index defined on lots of columns involved in NNSTAT operation 
or nickname creation. 
 
This error results from a limit on sum of the length of a 
nickname index columns, which is 640-bytes.
