You are about to plug a multi-terabyte non-CDB into an existing multitenant container database (CDB).
The characteristics of the non-CDB are as follows:
-Version: Oracle Database 11g Release 2 (11.2.0.2.0) 64-bit -Character set: AL32UTF8 -National character set: AL16UTF16 -O/S: Oracle Linux 6 64-bit
The characteristics of the CDB are as follows:
-Version: Oracle Database 12c Release 1 64-bit -Character Set: AL32UTF8 -National character set: AL16UTF16 -O/S: Oracle Linux 6 64-bit
Which technique should you use to minimize down time while plugging this non-CDB into the CDB?（）

Which statement is true？（） Compilation succeeds.。 class A does not compile.。 The method declared on line 9 cannot be modified to throw TestException.。 TestA compiles if line 10 is enclosed in try/catch block that catches TestException.。 某教师为大班积木区的教育目标制定为：“能为所建造的物体命名”，你认为这一目标（） 太笼统、太空泛。 不符合大班儿童年龄特征。 太抽象。 不够清晰。 论述铰孔时铰削余量过大的影响。 Which is the correct description of a pinned buffer in the database buffer cache（） The buffer is currently being accessed.。 The buffer is empty and has not been used.。 The contents of the buffer have changed and must be flushed to the disk by the DBWn process. 。 The buffer is a candidate for immediate aging out and its contents are synchronized with the block contents on the disk.。 某一220KV线路有两套保护，一套常规保护，一套微机保护，重合闸使用方式是（）。 微机重合闸停用，常规重合闸投用。 两套重合闸全投用。 常规重合闸停用，微机重合闸投用。
