I'm trying to generate a model file of an existing online domain but discoverDomain encountered a runtime exception.

The domain has a persistent store of type "JDBCStore" with a target "wls_server1". The store is configured with the property "create tabel from ddl file" with the value "weblogic/store/io/jdbc/ddl/oracle_blob_securefile.ddl".

The discoverdomain script can't handle this situation. When I remove the value of the property "create tabel from ddl file", the script ends normally.

The log file
discoverDomain.log.error.log

A part of the stdout.

However, you have a bigger issue in that JDK 17 is not compatible with WLS 12.2.1.4. Please drop back to JDK 8. Hopefully, this will clean up issues like:

Thanks, I'm currently performing a discover with 1.8.0_391 and so far no stacktraces :-)

@RogierEnders Another minor issue is that you are invoking discoverDomain.sh with both -skip_archive and -remote. Clearly, the code currently allows this but it really shouldn't--they should be mutually exclusive as they handle the no archive file scenario differently, as documented in paragraph 4 of the Discover Domain Tool docs. My current plan is to put logic into the tool startup to fail the tool if both options are specified. Thoughts?

Good to point that out. I was trying if I didn't get the error with -skip_archive but that obvious didn't solve it. When I turned back tot -remote I forgot the remove the other one.

Failing to start the domain discovery looks like a good plan.
