Listener Registration Process (LREG)
The listener registration process (LREG) registers information about the database instance and dispatcher processes with the Oracle Net listener (see "The Oracle Net Listener"). When an instance starts, LREG polls the listener to determine whether it is running. If the listener is running, then LREG passes it relevant parameters. If it is not running, then LREG periodically attempts to contact it.
Note:
In releases before Oracle Database 12c, PMON performed the listener registration.”
Excerpt From: Corporation, Oracle. “Oracle® Database Concepts, 12c Release 1 (12.1).”

Oracle Database 12c–Move Datafile Clause
Use the MOVE DATAFILE clause to move an online data file to a new location. The database can be open and accessing the data file when you perform this operation. The database creates a copy of the data file when it is performing this operation. Ensure that there is adequate disk space for the original data file and the copy before using this clause.
You can specify the original data file using the file_name, ASM_filename, or file_number. Refer to ASM_filename for information on ASM file names. If you identify the file by number, then file_number is an integer representing the number found in the FILE# column of the V$DATAFILE dynamic performance view or in the FILE_ID column of the DBA_DATA_FILES data dictionary view.
Use the TO clause to specify the new file_name or ASM_filename. If you are using Oracle Managed Files, then you can omit the TO clause. In this case, Oracle Database creates a unique name for the data file and saves it in the directory specified by the DB_CREATE_FILE_DEST initialization parameter.
If you specify REUSE, then the new data file is created even if it already exists.
If you specify KEEP, then the original data file will be kept after the MOVE DATAFILE operation. You cannot specify KEEP if the original data file is an Oracle Managed File. You can specify KEEP if the new data file is an Oracle Managed File.
Syntax:
MOVE DATAFILE ( 'filename' | 'ASM_filename' | file_number )
[ TO ( 'filename' | 'ASM_filename' ) ]
[ REUSE ] [ KEEP ]

Difference between PGA_AGGREGATE_TARGET and PGA_AGGREGATE_LIMIT
PGA_AGGREGATE_TARGET
| Property | Description |
|---|---|
| Parameter type | Big integer |
| Syntax | PGA_AGGREGATE_TARGET = integer [K | M | G] |
| Default value | 10 MB or 20% of the size of the SGA, whichever is greater |
| Modifiable | ALTER SYSTEM |
| Range of values | Minimum: 10 MB Maximum: 4096 GB - 1 |
| Basic | Yes |
- Only controls “tunable” memory allocations
- “Tunable” means the oprations can opt to use PGA or temp space, like hash join, sort, etc
- Actual PGA usage is often much higher (3x) since operations for “untunable” memory do not heed this parameter
- Particularly problematic with parallel queries with high DOPs, badly behaved PL/SQL
PGA_AGGREGATE_LIMIT (New in 12c)
| Property | Description |
|---|---|
| Parameter type | Big integer |
| Syntax | PGA_AGGREGATE_LIMIT = integer [K | M | G] |
| Default value | By default, PGA_AGGREGATE_LIMIT is set to the greater of 2 GB, 200% of PGA_AGGREGATE_TARGET, and 3 MB times thePROCESSES parameter. It will not exceed 120% of the physical memory size minus the total SGA size. |
| Modifiable | ALTER SYSTEM |
| Range of values | Oracle recommends that you do not set PGA_AGGREGATE_LIMIT below its default value. PGA_AGGREGATE_LIMITcannot be set below its default value except in a text initialization parameter file (pfile) or binary server parameter file (spfile). If a value of 0 is specified, it means there is no limit to the aggregate PGA memory consumed by the instance. |
| Basic | No |
PGA_AGGREGATE_LIMIT specifies a limit on the aggregate PGA memory consumed by the instance.
There is no difference in behavior between PGA_AGGREGATE_LIMIT being explicitly set or being set to the default.
Actions Taken When PGA_AGGREGATE_LIMIT is Exceeded
Parallel queries will be treated as a unit. First, the sessions that are using the most untunable memory will have their calls aborted. Then, if the total PGA memory usage is still over the limit, the sessions that are using the most untunable memory will be terminated.
SYS processes and background processes other than job queue processes will not be subjected to any of the actions described in this section. Instead, if they are using the most untunable memory, they will periodically write a brief summary of their PGA usage to a trace file.
What is the value for PGA_AGGREGATE_LIMIT if value is 0? Either not set or under AMM control.
