我向数据库上的用户授予了连接权限：
$ db2 grant connect on database to user dbuser
DB20000I The SQL command completed successfully.
但是当我尝试授予select权限或dbadm时，它会给我一个错误，说用户没有授予权限，但我用于连接，选择和dbam
$ db2 grant dbadm on database to user dbuser
DB21034E The command was processed as an SQL statement because it was not a
valid Command Line Processor command. During SQL processing it returned:
SQL0552N "TSSADM" does not have the privilege to perform operation "GRANT".
SQLSTATE=42502
根据GRANT (database authorities) statement，您的用户必须在数据库中拥有SECADM权限才能授予DBADM。您的用户是否拥有此权限？
