Remaining Online When Server Connection is Lost
The Attention - Connection to server is unavailable! dialog box alerts you when a server or network failure occurs during a server transaction and you lose connection with the server. It prompts you whether you want to go offline.
You can explicitly choose to stay online or go offline. Click No in the Attention - Connection to server is unavailable! dialog box to remain online. Alternatively, you can set the dm_offline_after_event configuration option to no so that No is the default option.
If you remain online, you can attempt the server transactions that terminated abruptly when the server connection was lost. The Creo application also tries to reestablish connection with the server. The server and the workspace are not in synchronization, but synchronization is eventually achieved.
