RMAN delete archive log and cross check

ORA-00257: archiver error. Connect internal only, until freed.

then delete old archive log



RMAN delete archive log file


This will delete all the archive log before SYSDATE-2

RMAN> delete noprompt force archivelog until time 'SYSDATE-2';



Or

RMAN> delete force backup completed before 'sysdate - 1';


IF the archive log no longer there (delete) you need to do crosscheck to make RMAN know that this file is not available for backup anymore :


RMAN> crosscheck copy of archivelog all;




RMAN> show all;

RMAN configuration parameters for database with db_unique_name ORCL are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

Oracle 10g RMAN DURATION

RMAN duration



RMAN> BACKUP DURATION 1:00 TABLESPACE anuj;

RMAN > BACKUP DURATION 3:00 DATABASE PLUS ARCHIVELOGS;


DURATION hh:mm -> Specifies a maximum time for a backup command to run , if backup not
complete upto this time , then RMAN backup will stop



RMAN> backup device type disk format='/home/oracle/RMAN/reportA%U.bkp' as compressed backupset duration 1:00 minimize load database;



to check RMAN BACKUP

select message,time_remaining from v$session_longops where sid=XXX and sofar<>totalwork;



[PARTIAL][MINIMIZE (TIME|LOAD)] -> With disk backups, you can use MINIMIZE TIME run the backup at maximum speed (default)

MINIMIZE LOAD to slow the rate of backup to lessen the load on the system. With MINIMIZE LOAD the backup will take the full specified duration.
