Backup pluggable database - oracle

I have a pluggable database and I want to backup.Now,I did this in windows:
set ORACLE_SID=ORE(My pdb name)
echo ORACLE_SID
rman target /
But,I ran into these errors:
RMAN-06171(Not connected to target database)
Can anyone please advice what my target db should be? I want to backup my pdb and not container db.

You should connect to the container database in order to perform backups. After that you can run
BACKUP PLUGGABLE DATABASE pdb_name;
Refer to the official documentation:
Backing Up PDBs with RMAN
Also, your connection does not work, because there is no database instance with name of the pluggable database - only the container instance is running and pdbs are stored in it.

Restoration and Recovery of PDB (Pluggable database), we need to ensure that valid rman backup available.
SQL>restore pluggable database PDBORCL1;

Can we recreate pdb$seed in Oracle database 19c

I have lost by mistake the pdb$seed from my multitenant architecture of database.
Is there some possible way to recreate the same?
If you happen to have a regular PDB that was created from the seed database, you can close this regular PDB into a new seed database.
If you have already made changes to the regular PDB, the easiest is to create a (temporary) new CDB (which comes with a fresh seed database) using the Database Creation Assistant and clone the seed database from the temporary CDB to your CDB. After that, drop the temporary CDB.

Oracle database recovery

I was living in Ukraine, Kharkov. Now moved to another place due to war with Russian. Back there in Kharkov I had HP ProLiant server with Oracle database. Before escape city I did copy of file system to my laptop. Oracle Linux installed on laptop.
Is it possible to restore/run database instance with all my database schemas/users from that copy of filesystem?
I'm Java and PL/SQL developer. But I'm not Oracle administer, Oracle is quite complex system and it hard to run it for me from copy of filesystem.
As well, I managed to get all 4 SAS drives from server and took them with me. But I do not have a server here, I'll try to find someone who has one.
Please guide me or give some ideas what could I do to run database again. Or export and import data to new database.
The following will work if you have the same file paths as on your original Oracle database.
Create new database.
Shutdown immediate;
Change your command window to the same directory that the backups are in.
Launch RMAN with new database as target
The following are the rman commands you will be issuing:
startup nomount;
restore controlfile from '<<file path to control file>>';
shutdown immediate;
startup mount;
restore database;
recover database;
alter database open resetlogs;

Can we create backup job on Oracle PDB instance?

Can anyone help me on the below?
Is it possible to create backup jobs in oracle pluggable databases or the backup jobs can be created only on the root container database?
RMAN can execute on a PDB as well. You need a user with SYSBACKUP privileges to connect directly to the PDB. See this link for specifics:

Oracle 12c Cloning PDBs from disk

In Oracle 12c is it possible to clone/duplicate a PDB into a different CDB using a disk backup?
So if I take a backup to disk as follows, can I then clone from this backup into a new PDB in a different CDB?
RMAN> connect target "c##oradbmaint/temp1234 as sysbackup"
connected to target database: TEST44 (DBID=958109427)
RMAN> connect catalog rman/*****#RMANCATDB
connected to recovery catalog database
RMAN> backup pluggable database PDB001 to destination '/u01/app/oracle/backup';

How to clone Oracle database from one service name to other service name?

I have Oracle database and I know SYS password and service name.
I don't have access to database server.
I want to clone database and want to deploy this copy on this database server, but I want have other service name for access to copy.
For example: first base connection string is localhost:1521/sn1, and clone have connection string localhost:1521/sn2copy.
It is possible?
RMAN has the ability to clone a database.
take a look at the RMAN DUPLICATE command.
It's actually documented in the Oracle documentation: Creating a Duplicate Database on the Local Host
.
And also see (from the ORACLE-BASE Blog): Duplicate a Database Using RMAN in Oracle Database 11g Release 2
