When the database import package is installed during TCM installation, the database cannot be connected, as shown in the following figure:
The database import package is installed on the TCM server first. If this problem occurs during the installation, install the data package and the DB server together. Do not install the data package on the same VM with the TCM server.
The TCM can identify only the local database. The corresponding database cannot be found according to the username and password of the database.
