You are creating an additional database by using the Database Configuration Assistant (DBCA). You opted to create a General Purpose database and during the database creation realize that the Block Size field is not enabled. What could be the reason for this?
A.You have chosen the File System option as the storage option.
B.You have chosen the Automatic Storage Management (ASM) as the storage option.
C.The data block size can be increased only when DBCA is invoked from Oracle Universal Installer (OUI).
D.You are using General Purpose template and not the Custom Database template to create the database.
是因为之前创建数据库时，选择的是按照一般目的模板来创建的，故块大小为固定的，不能改。
