Primary and standby databases
I am creating a new database standby that will receive the archive logs from the primary productive database. Could the primary database go down if there is a communication problem between the primary and standby databases? What happens to the primary one if the archive logs can't reach the standby database?

Step 2 of 2:
If you lose communication from your primary database to your standby system, then how your primary database reacts depends on how you configured your primary database. You'll have to look to your LOG_ARCHIVE_DEST_n parameters. The LOG_ARCHIVE_DEST_n parameters have many options. If you include the MANDATORY option in this parameter, then it is mandatory that the standby database receives the archived redo log. If you use the OPTIONAL option instead (which is the default), then the standby database does not have to receive the archived redo log.
