问题
I've installed Sqldeveloper Version 19.1 64-bit Version on an enterprise PC with Win7-64bit.
It works fine with embedded jdbc-client, but I need to get it working using the Oracle OCI-client.
Using an OCI-client (thick-driver) requires for sure a client like instantclient_12_2. I have no admin privileges on my workstation and so copied the full instantclient_12_2 to the enterprise PC.
Since I'm not allowed to change the %PATH% myself, I created a start.bat file with required settings, because without, it also won't work (already tried).
PATH="C:\Users\myuser\OneDrive\Oracle\instantclient_12_2";%JAVA_HOME%;%PATH%
C:\Users\myuser\OneDrive\Oracle\sqldeveloper64\sqldeveloper.exe
When I try to configure another Oracle-Client without this change, I get another error, that PATH to instantclient needs to be defined before any others.
Now, starting sqldeveloper with this bat-file works fine. Connections can be established using the internal jdbc client.
Then, I've configured the Oracle Client in SQLdeveloper (Preferences/Database/Advanced) and selected the instantclient directory.
Pressing the "Test" button opens the Messages log "Oracle Client Test Results - Log" and shows an error.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occured, Program will exit.
Unrecognized option: -
Now, I'm lost, because I'm not a Java-Expert. I'm wondering, why sqldeveloper as Java-tool is running, but the instant-client says it can't create the JVM.
The reason for me to use OCI-client is, that it has e.g. better support of User-breaks.

Meanwhile, I've solved it.
Result of testing:
Testing the Instant Client located at C:\Users\myuser\Oracle\instantclient_12_2
Testing client directory ... OK
Testing loading Oracle JDBC driver ... OK
Testing checking Oracle JDBC driver version ... OK
Driver version: 12.2.0.1.0
Testing testing native OCI library load ... OK
Success!
Reason were following mistakes:
- Forgot "set" in front of Variable assignment (because I'm usually using Unix)
- Used quotation marks during Variable assignment, which are taken as part of the value (also different to UNIX).
- Added JAVA_HOME and JRE_PATH
See below my complete bat-file (adapted, because of some secret information within pathnames):
REM Optional: setting of USE_OS_DATETIME_FORMAT changes DATE-Format
set USE_OS_DATETIME_FORMAT=1
set JAVA_HOME=C:\Users\myuser\OneDrive - myCompany\Oracle\sqldeveloperx64.19.1\jdk
set JRE_PATH=C:\Users\myuser\OneDrive - myCompany\Oracle\sqldeveloperx64.19.1\jdk\jre
set PATH=C:\Users\myuser\OneDrive - myCompany\Oracle\instantclient_12_2;%JAVA_HOME%;%PATH%
REM Start sqldeveloper with new local environment:
"C:\Users\myuser\OneDrive - myCompany\Oracle\sqldeveloperx64.19.1\sqldeveloper.exe"
Additionally, I've added a shortcut to the bat-file and now I can start it simply with CRTL-SHIFT-S ;-)
BTW: Same solution works fine on Win10 as well
