Cause
The schema name looks something like BITBUCKET-USER. Oracle Database does not accept hyphen (-) in the schema name, hence this error.
Solution
Follow the below steps to use a different schema for your Oracle Database and use that while connecting the Oracle Database to Bitbucket:
Create another user with a name that doesn't have a hyphen (-) and has an underscore (_) instead, or just one word like "
bitbucketuser"Add/modify the Database information in the
<Bitbucket-home>/shared/bitbucket.propertiesfile.
Please refer to this page for more information: Connect Bitbucket to Oracle.
