We have environment with Primary and Active standby Dataguard. For some reason storage on Dataguard is crashed and I had rebuild the Dataguard DB from backup. Noticed Archive log is not being shipped and when I look at alert log found following errors.
FAL[server, ARC3]: FAL archive failed, see trace file.
Errors in file /local/opt/oracle/diag/rdbms/xnodbcor/XNODBCOR1/trace/XNODBCOR1_arc3_2216.trc:
ORA-16055: FAL request rejected
ARCH: FAL archive failed. Archiver continuing
ORACLE Instance XNODBCOR1 – Archival Error. Archiver continuing.
Checked parameter values on archive_dest on primary DB and noticed “RESET” value assigned to ” log_archive_dest_state_1″
log_archive_dest_state_1 string RESET
Enabled the dest_1 as below, that fixed the problem. Error disappeared and logs are being shipped and applied on Standby site.
SQL> alter system set log_archive_dest_state_1=enable;
SQL> alter system switch logfile;
