Free 1z0-062: Oracle Database 12c Installation and Administration Exam Questions and Answers
Oracle Database 12c Installation and Administration is part of Oracle Certification from Oracle University. Oracle exam codes begin 1Z0-, and modern ones end in the release year, so 1Z0-1085-26 is the 2026 release of OCI Foundations Associate. The least-known rule is the update path: a Delta exam swaps the prefix to 1D0- and appends -D while keeping the same family number, so 1Z0-1058-26 renews through 1D0-1058-26-D.
If you searched for 1z0-062: Oracle Database 12c Installation and Administration dumps, an ExamTopics discussion or a free PDF, this is the question bank for it: practice questions with verified answers and explanations, a timed practice test and updates whenever Oracle changes the exam.

Question #2
You configure your database Instance to support shared server connections. Which two memory areas that are part of PGA are stored in SGA instead, for shared server connection? (Choose two.)
Select 2 answers.
Correct answer: C, E
Explanation
A: PGA itself is subdivided. The UGA (User Global Area) contains session state information, including stuff like package-level variables, cursor state, etc. Note that, with shared server, the UGA is in the SGA. It has to be, because shared server means that the session state needs to be accessible to all server processes, as any one of them could be assigned a particular session. However, with dedicated server (which likely what you're using), the UGA is allocated in the PGA. C: The Location of a private SQL area depends on the type of connection established for a session. If a session is connected through a dedicated server, private SQL areas are located in the server process’ PGA. However, if a session is connected through a shared server, part of the private SQL area is kept in the SGA. Note: * System global area (SGA) The SGA is a group of shared memory structures, known as SGA components, that contain data and control information for one Oracle Database instance. The SGA is shared by all server and background processes. Examples of data stored in the SGA include cached data blocks and shared SQL areas. * Program global area (PGA) A PGA is a memory region that contains data and control information for a server process. It is nonshared memory created by Oracle Database when a server process is started. Access to the PGA is exclusive to the server process. There is one PGA for each server process. Background processes also allocate their own PGAs. The total memory used by all individual PGAs is known as the total instance PGA memory, and the collection of individual PGAs is referred to as the total instance PGA, or just instance PGA. You use database initialization parameters to set the size of the instance PGA, not individual PGAs. References:
