I have a backup.dmp file, which is backup file of my database built in oracle. please suggest me how can I see tables, schema etc stored in that backup.dmp ? should I install some software to open this backup.dmp file.
Thank you in advance.
.dmp files have been generated by oracle tools (data pump or maybe export). To exploit this files, you need to install Oracle (try for exemple oracle 10g express) and then use the import(imp) or data pump (impdb)
You can view the dump file contents using Toad (must be fully licensed with the DBA extension), imp or impdp.
impdp scott/tiger#orcl directorory=dpump sqlfile-abc.sql dumpfile=xyz.dmp and logfile=xyz_log.log full=y
Or
imp scott/tiger#orcl file=abc.dmp show=y log=abc_log.log full=y
These commands will create viewable DDL of the actual DB creation.

I have a Microsoft background and I'm learning Oracle products.
I was able to import Oracle Database 19c Sample Schemas on a Docker Oracle image from command line following this guide.
I now would like to know if there is a way to import the same sample through a GUI using Oracle SQL Developer.
With SSMS is quite simple to import/export databases, row data, CSV, etc... but I don't see the same tool for Oracle SQL Developer.
EDIT:
#thatjeffsmith suggested to right click on tables > Data Import Wizard, but when I select "db-sample-schemas-master" I only find the samples with .sql files in it and .sql files cannot be imported with this tool
It depends.
The .SQL files can be ran through the SQL worksheet via F5 no problem.
The sqlldr scenarios, you could rename the .dat files to .dsv files.
Right click on your table, like Sales History SH entries, choose Import Data, and walk the wizard.
But, it would be much easier to just follow the instructions as is, especially if you are new to Oracle.
I received an Oracle 11g database for parsing, but the dump file is in .datp format. I have not found anywhere on the internet reference about this type of file linked to OracleDB Schemes. The client's instructions are "have to use Oracle to read it" but:
1- I have superficial knowledge in Oracle
2- this database will be migrated to MySQL
3- I have Oracle XE 11g installed but neither does it have any tools that open this file (at least not apparently).
Any light on how to open and import this database for Oracle or MySQL?
If it's a dump file then most likely it's an export from either the old EXP utility or the newer Datapump export (expdp).
The file extension is not standard but seems to point to DATaPump. If so you can import it into an Oracle database using Datapump import utility, impdp. Find out more.
If that doesn't work, try original imp instead. Find out more
I have back up file for oracle 11g.(.bak file)
How to restore .bak file in Oracle 11g.Please, anyone, help me.I am new in Oracle.

In Toad, SQL statements can be saved as Named SQL. How can I take backup of named SQL statements and restore when Toad crashes or use in another PC or computer.
Appreciate any insight.
I do not know which version you have. By me is in:
C:\Users\UserName\AppData\Roaming\Dell\Toad for Oracle\12.9\User Files\SavedSQL.xml
See all *.XML files in the same directory. There are connections, code templates and more
How can i import a DMP file into my oracle 10g expression edition database?
I tried with imp but its showing an error:
IMP-00010: not a valid export file, header failed verification
IMP-00000: Import terminated unsuccessfully
How can i solve this?
Make sure the exp was done with a version of 10g that is lower or equal to the version of the oracle 10xe. If it was done with expdp instead of exp, you will not be able to import it using imp. You can not import a dump file into an older db an exp that was done with the exp of a newer version. I would suggest you find out what the exact version of the exp tool used and if it was exp vs expdp. If necessary use the exp tool from the 10xe and exp what your need remotely from the 10g enterprise db. Then you be ensure you can imp it.
I fear that there is no easy way to import this DMP file with that error message. Are you sure that the DMP file was exported with exp and that nobody has tampered with it aftwerwards. Maybe this is a shot in the dark but possibly you have transfered the DMP file with FTP and forgotten to turn on binary mode.
Oracle Utlities Guide states that The Import utility cannot read export dump files created by the Export utility of a later maintenance release or version. For example, a release 9.2 export dump file cannot be imported by a release 9.0.1 Import utility.
Now, I am not sure if oracle 10g enterprise edition is considered a later maintenance release compared to oracle 10g express. Anyway, I'd try to use the same exp and imp version, propably the one of oracle 10g express.
