Migration access to Oracle using SQL Developer

I have to Migrate Access Office 365 database to Oracle 19c using sql developer 19.2 but when I open sql developer connection there is no option for access. Only all I can see for Oracle where I successfully connected to Oracle.
Can anyone help me how can I connect to access database and successfully migrate database to Oracle?
Thanks for your help in advance!

Chandar
Perhaps it would be better to migrate Access database to SQL Server first (also called "upsizing"), and then to migrate the SQL Server database to Oracle.

Need info on oracle driver compatibility

I am a newbie to oracle database, could anyone please help me here.
I can not find drivers for oracle 9.2 so i used oracle 10g instead. i am also able to connect to database but when i am querying; i am not getting any results. (I am using Powerbuilder 12.6 for development)
Apparently i would like to know compatibility of oracle drivers. Does Oracle 10g drivers supports oracle 9i ?
I tried oracle website and documentations but nothing helped me.
The PowerBuilder drivers communicate with Oracle Client, not the server. Your choices for PowerBuilder drivers are O90 (Oracle 9i), O10 (Oracle 10g), and ORA (Oracle 11g).
The Oracle Client and the Oracle database server wouldn't have to match but your application will be restricted to use features supported by the client and server.

PostgreSQL to Oracle Database with Oracle GoldenGate 11.2.1

I've spent 2 days to sync postgresql database to oracle. Read few books, googled many times..
1. I have setup PostgreSQL on CentOS 6.5 (A) also installed oracle database on this VPS. copied GoldenGate to it.
2. I have already setup 2 oracle VPS using Goldengate and setup as Source (B) and Target (C). I'm trying to sync PostgreSQL to Target VPS.
3. GoldenGate runs on A server without error.
The problem is when I setting up it requires ODBC config (page 14). I'm new to PostgreSQL so little confusing for this..
Also when I google i find only to postgresql from oracle.
Main doc I'm following is http://docs.oracle.com/cd/E35209_01/doc.1121/e29642.pdf
Actually I have found Oracle Golden Gate new features https://blogs.oracle.com/dataintegration/resource/2013-DIFamily/OGG_WinUnix_Rel_Notes_11.2.1.0.7.pdf
Oracle Golden Gate don't support what I want to do.
They say:
Oracle GoldenGate introduces support for PostgreSQL. This support includes the mapping, manipulation,
filtering, and delivery of data from other types of databases to a PostgreSQL database. Oracle GoldenGate
does not support the capture of data from PostgreSQL to other PostgreSQL databases or to other kinds of
databases.
GoldenGate does not support Postgres as a source - only target.
Check out Attunity for what you are trying to do.
Postgres support was only for delivery in Oracle GoldenGate 12.2. Oracle is working on a full capture/delivery support for Postgres. It will be out in a later release post 19c. Please check the OTN website for versions.

Oracle 11g Backward compatibility with older oracle releases

Our organization is planning to upgrade its most of the oracle servers & clients to 11g Release 2.
But one of our client system is still using oracle 8i installation.
Can we able to access the objects of Oracle 8i from oracle 11g client?
Some blogs says that it should work and other say it won't.
Can anybody faced any issue with such configuration.
One of the senior dba told us that oracle only supports backward compatibility of 2 versions earlier to current version. Assuming this fact we shouldn't been able to access database objects running on oracle version 8.
Kindly help.
Thanks in advance.
We had to revert to Oracle 10 client (10.1, I believe) in order to connect to an Oracle 8 database. If there is a way to do it using 11.2, I'd like to be schooled.
EDIT: 10.2 will work. Here's the official word:
http://www.oracle.com/technetwork/database/windows/install10202-083849.html
"Access to an Oracle Database Server (Oracle8i Release 3 or later)"
And as of 11.1, you're out of luck:
http://www.oracle.com/technetwork/database/windows/install11106-087844.html
"Access to an Oracle Database Server (Oracle9i Release 2 or later)"
Oracle doesn't even list version 8 in any compatibility tables on their web site. We verified that current (11g R2) JDBC drivers from Oracle do not work with Oracle 8 database sources. It means that it is not possible to access Oracle 8 databases from the latest version of Oracle SQL Developer because it is using JDBC driver.
While there is a slim chance to be able to access Oracle 8 from some other Oracle 11g client, I would not bet my business on that.
