Oracle Par File Comments
Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP, Data Mining and Real Application Testing options. Use a command file. A command file is a text file residing in the file system. Use a stored script. This script is stored in the Oracle RMAN catalog database and executed from the Oracle RMAN command prompt. Command Files. Oracle RMAN command files are plain-text files and similar to shell scripts in UNIX or batch files in Microsoft Windows. What is the best way to add comment format in the sqlldr control files using -- or /* comment */. A parameter file is a text file listing the parameters for Oracle 12c’s Data Pump Export or Import and setting the chosen values. Data Pump Export and Import parameter files are constructed the same way. Follow these steps to run a Data Pump Export with this parameter file: Type the parameter file into a text editor and save it to a directory.
Update:
Oracle Comments In Sql
I have never used oracle database before. I have .dmp file which is of 50 gb. I dont know how it was exported or which version it was exported from. I downloaded oracle 12c realease 2 and tried to do an import but I get the error '.dmp may be an Data Pump export dump file'. What do I need to do so that I can run sql queries on it eventually. Please see the attached image.
UPDATE :I tried the command : IMP SYSTEM/Password SHOW=Y FILE=DBO_V7WRIGLEY_PROD_20180201_TECHOPS-5527.dmp fromuser=SYSTEM touser=SYSTEM
It gave me a message saying import terminated successfully with warnings. what does this do ? Also where can I view the data now if its imported ?

in sqlplus as SYSTEM:
back in command line:
when done, you can remove the DIRECTORY object
in a CDB database (which is your case), this will not work, unless you pre-create all the users and roles in SQLPLUS, after running this command:
Otherwize, you can create a PDB inside your CDB and import your DMP file into the PDB. In this case, you'll need to modify the connection in the IMPDP command as follows (change SYSTEM/Password to SYSTEM/Password@//localhost/pdb_name) :
First of all, you should use impdp instead of imp. And don't forget to take backups before doing anything. Also, you should have your dmp file on your server's local directory. I've seen people trying to import dmp files located on their computer's hard drive. That's not how things work.
I recommend you to drop the schema if you are importing to an existing schema for better results.
To drop an existing schema, login to sqlplus with an admin account
sqlplus username/password@connect_identifier

Then you can use this command to drop the schema:
Query your DB to see if data pump directory is defined
If directory is not defined use this command to define (btw 'D:orcl12' is my oracle instance path, you should use your own path)
Quit sqlplus to command prompt and run impdp with admin credentials (Be sure there's no other logfile with the same name on source directory - if so operation will abort)
impdp username/password@connect_identifier directory=DATA_PUMP_DIR dumpfile=filename.dmp logfile=filename.log
If the operation succeeds you may have to update User-Defined Datatypes manually because they are not importing correctly.

Is there a way to put comments in a data pump export parameter file?

Yes, by using # at the start of a line.
Actually everything after the # sign will be ignored, so this can be used after a parameter as well.
This is a bit hidden in the manual:

Table names specified on the command line cannot include a pound sign (#), unless the table name is enclosed in quotation marks. Similarly, in the parameter file, if a table name includes a pound sign (#), then the Export utility interprets the rest of the line as a comment, unless the table name is enclosed in quotation marks
