ORACLE Instance testdb3 - Archival Error
ORA-16014: log 4 sequence# 558 not archived, no available destinations
ORA-00312: online log 4 thread 1: '+DATA/testdb3/onlinelog/group_4.266.944679837'
Archiver process freed from errors. No longer stopped
Cause :
In my case the problem was log_archive_dest_2 was set incorrectly.
SQL> show parameter log_archive_dest_1;
NAME TYPE VALUE
------------------------------------ --------------------------------- ------------------------------
log_archive_dest_1 string LOCATION=/holding/testdb3/archive_logs
valid_for=(online_logfile, all_roles)
Solution :
SQL> ALTER SYSTEM SET log_archive_dest_1='LOCATION=/holding/testdb3/archive_logs valid_for=(all_logfiles,all_roles)' scope=both;
System altered.
