If you select to use the MySQL, PostgreSQL or SQL server database to store the analysis results, the database is created automatically by the installer. However, when you select to use the Oracle database you must create the database and the schema before installing the Portal via Talend Installer.
When defining the database to store analysis results, you must:
make sure that users of the Portal are granted the right privileges on different databases as described in Privileges in databases.
make sure, for the PostgreSQL database, to add the IP of the computer which will install the Portal on the PostgreSQL server.
