Initializing the Database System as a Non-admin Database User

Logi JReport Server needs to connect to a server database and fetch and write data from the database tables at runtime. Database initialization is to create the required tables in the database. Usually, Logi JReport Server automatically creates database tables the first time it is started. The database information that Logi JReport Server uses is defined in the dbconfig.xml file. However, if the user ID defined in this file does not have the permission to create tables in the database, Logi JReport Server will fail to complete the operation. In this case, you will need another user, such as the database administrator who has the relevant permissions, to create a set of empty tables in the user's schema using the provided SQL files in <install_root>\script_files.

In the case when a database administrator (DBA) does not want to assign an admin database user to Logi JReport Server for connecting to the database, Logi JReport has to use a non-admin database user to initialize the database system. The database initialization will then have to be divided into three phases:

1. The DBA creates new database tables using script files stored in <install_root>\script_files\create_new_tables.
2. Customer starts Logi JReport Server using a non-admin database user. In this phase, the data in the old version's database tables if they exist will be migrated to the new tables created in the first step. If the data migration happens, you will be able to see a record of it in the debug file.
3. The DBA deletes tables of the old version in the database using script files stored in <install_root>\script_files\delete_old_tables.

If it is a newly installed Logi JReport Server connecting to a database that does not already contain the required tables, only the first step is required.

The following table lists the script files used for different purposes:
