oracle19c - Oracle XE 18c impdp dump from 19c

Question

I have a dump file that is created using expdp from Oracle 19c (exported with version parameter 18). Is it even possible to import the dumpfile to an Oracle 18c XE database? The structure and everything else from the 19c database is unknown to me. I just got the 13gb dumpfile.

While using impdp it says:

Connected to: Oracle Database 18c Express Edition Release 18.0.0.0.0 - Production
ORA-39002: invalid operation

Thats it.

In /opt/oracle/diag/rdbms/xe/XE/trace/alert_XE.log it says:

XEPDB1(3):DW00 started with pid=62, OS id=23288, wid=1, job SYSTEM.SYS_IMPORT_FULL_01
2020-12-09T15:25:55.364764+00:00
XEPDB1(3):Resize operation completed for file# 9, old size 266240K, new size 276480K

Is there a another logfile I don't know about?

Anyways, my command looks like this:

impdp user/password@localhost/xepdb1 DIRECTORY=import_dir DUMPFILE=dump.expdp nologfile=y version=18 full=y

Yes, the user is privileged to do so. Yes, the import_dir is set with CREATE DIRECTORY and the user is also privileged to use this directory.

I'm lost.

edit: I used stackoverflow for many years now and this is my very first question since I'm NEW to oracle in general and as I stated above: I'm lost.

2nd edit: It's still the same error even after I try to partially import the dump with parameters like tables=

Perhaps your dump file is too big. Oracle XE has some limitations.

See the Oracle documentation: https://www.oracle.com/database/technologies/appdev/xe.html

Resources:

• Up to 12 GB of user data
