Faced the same issue. Recreated tablespace as "jiratbs". Recreated user without the option  TEMPORARY TABLESPACE. Seems the problem has gone.

Hi @liudaxia ,

Please confirm that you're following the steps found here:

https://confluence.atlassian.com/doc/migrating-to-another-database-148867.html

Most importantly, the versions of Confluence must be the same.

Also, confirm that the Oracle database is configured correctly.
