hi to all,

Archivelogs are not shipping automatically.tnsping to PROD_STBY working fine. Neither Bandwidth issue nor firewall issue.
pfile has following entry :log_archive_dest_2='SERVICE=PROD_STBY reopen=60'
When we do following command on Primary
SQL> select status, Error from v$archive_dest where dest_id=2;
