Importing an Existing Database from a VCS Server¶
Instead of enabling version control for an existing database, you can import a database created by another user, from a VCS repository. To do this, click Import database to open the “Import Remote Databases” dialog.
When opening this dialog, Virtual DataPort connects to the VCS server set in the “Configuration” dialog of the “Administration > VCS management” menu and retrieves the Virtual DataPort databases stored in this VCS server.
Click and in the “Remote database” list, select the database you want to import. In the “Local name” box, you can change the name that the database will have locally. Then, click Ok.
You can import several databases simultaneously by clicking and selecting another database.
The imported databases use the default VCS configuration (this can be changed later).
When the check box Include jars and I18n maps is selected, the Server enters in “single user mode” to import the metadata from the VCS server. This means that the Server will queue all the queries executed after clicking “Ok”. If this check box is cleared, the queries to other databases will be executed during the import process and also, the import process will be executed faster. The drawback is that the jars and the i18n maps stored in the VCS server will not be imported. If this check box is cleared and the imported elements rely in I18n maps or jars that have not been imported, the import will fail, but you can repeat this operation again, selecting this option.
If the check box Resolve conflicts automatically is selected, Virtual DataPort tries to detect and solve conflicts when importing a database that depends on global elements (i18n maps and jars). This makes the import process slower.
Let us say we are in this scenario:
- You have a jar called “jar_1” that is versioned and that has been modified locally but you have not checked-in the changes.
- You import the database “DB_1” that depends on “jar_1”, selecting “Include jars and I18n maps” and clearing “Resolve conflicts automatically”. The import fails because there is a conflict between the local “jar_1” and the one stored in the VCS server.
- If you open the “Import Remote Databases” dialog again and select “Resolve conflicts automatically”, the Server will overwrite the local “jar_1” with the version stored in the repository.
After disabling and enabling the VCS integration of a database or changing its “URL” of the VCS server, all the VCS metadata of the database will be lost. That is, you will have to check in again all the elements of the database.
