To answer this question, you need to understand the different backup formats used for database backups.

Option A) backup set only - This option is correct because a backup set is a logical backup format that can be written to tape. It includes all the necessary data and metadata to restore the database.

Option B) image copy only - This option is incorrect because an image copy is a physical backup format that cannot be written directly to tape. It is a bit-for-bit copy of the database files and is typically used for faster recovery.

Option C) only user-managed backup - This option is incorrect because it does not specify a specific backup format. User-managed backup refers to the process of manually performing backups, but it does not specify the format.

Option D) both image copy and backup set - This option is incorrect because although both backup sets and image copies are valid backup formats, only the backup set can be used for writing to tape as specified in the question.

Option E) only incremental image copy backup - This option is incorrect because it specifies a specific type of backup (incremental image copy) rather than a format. Incremental backups only copy the changes made since the last backup and do not provide a full backup of the database.

Therefore, the correct answer is option A) backup set only. This option is correct because a backup set is a logical backup format that can be written to tape.

To recover the locally managed temporary tablespace after a tempfile has been deleted at the operating system level, the correct option is:

D. Drop and re-create the tablespace.

Explanation: When a tempfile is deleted at the operating system level, the associated locally managed temporary tablespace becomes unusable. To recover the tablespace, you need to drop and re-create it. This process involves dropping the existing tablespace and then creating a new tablespace with the same name.

Flashback the database (Option A) is not applicable in this scenario, as it is used to restore the database to a previous point in time.

Performing a point-in-time recovery (Option B) is not necessary in this case, as it is used to recover the database to a specific point in time.

Performing a full database recovery (Option C) is not required for a locally managed temporary tablespace recovery.

Using recovery manager (RMAN) to recover the database (Option E) is not applicable in this situation, as the issue is specific to the temporary tablespace.

Therefore, the correct answer is D. Drop and re-create the tablespace.

To answer this question, you need to understand the concept of Automatic Shared Memory Management (ASMM) and the background processes involved in managing the memory component.

ASMM is a feature in Oracle Database that dynamically manages the size of the System Global Area (SGA) components, such as buffer cache, shared pool, and large pool. It automatically adjusts the sizes of these components based on the workload of the database.

The background process that ASMM uses to coordinate the sizing of the memory component is called Memory Manager (MMAN). The MMAN process is responsible for dynamically managing the memory allocation and deallocation within the SGA.

Let's go through each option to understand why it is correct or incorrect:

Option A) PMON - The Process Monitor (PMON) process is responsible for process recovery and cleaning up resources when a user process fails. It is not involved in coordinating the sizing of the memory component in ASMM.

Option B) SMON - The System Monitor (SMON) process performs recovery and cleanup operations during database startup and shutdown. It is not involved in coordinating the sizing of the memory component in ASMM.

Option C) MMNL - The Memory Monitor Light (MMNL) process is responsible for monitoring and managing the Automated Maintenance Tasks. It is not involved in coordinating the sizing of the memory component in ASMM.

Option D) MMAN - The Memory Manager (MMAN) process is responsible for coordinating the sizing of the memory component in ASMM. It dynamically manages the allocation and deallocation of memory within the SGA.

Option E) MMON - The Manageability Monitor (MMON) process is responsible for collecting and managing performance data for the Oracle database. It is not directly involved in coordinating the sizing of the memory component in ASMM.

The correct answer is Option D) MMAN. This option is correct because the Memory Manager (MMAN) process is the background process used by ASMM to coordinate the sizing of the memory component.
