Archiving not possible: No primary destinations errors

If space ran out in an archive destination, after you fix the problem, you may still recieve the following error in your alert_log:

ARC1: Archiving not possible: No primary destinations

A quick way to solve this is to modify your archive destination with the reopen
parameter. This parameter specifies the minimum number of seconds
before redo transport services should try to reopen a failed
destination.

SQL> show parameter log_archive_dest_1

NAME TYPE VALUE
------------------------------------ ------- ------------------------------
log_archive_dest_1 string location=/db/orcl/archive

SQL> alter system set log_archive_dest_1='location=/db/orcl/archive reopen=5' scope=both;

System altered.

Following that modification you should start seeing successful archive messages in your alert_log.

ARC1: Beginning to archive log# 1 seq# 115127
...
ARC0: Completed archiving log# 1 seq# 115127
...
