RMAN-06059 expected archived log not found
Hello experts
Very often the RMAN backup notice me the following error:
RMAN-06059 expected archived log not found, lost of archived log compromises recoverability
ORA-19625: error identifying file +BD2/db/archivelog/2011_01_27/thread_2_seq_6794.4744.741546565
ORA-17503: ksfdopn:2 Failed to open file +BD2/db/archivelog/2011_01_27/thread_2_seq_6794.4744.741546565
ORA-15012: ASM file '+BD2/db/archivelog/2011_01_27/thread_2_seq_6794.4744.741546565' does not exist
Normaly I do a crosscheck of archivelog all, then I remove expired archivelog all and finally I do a level 0 backup. That solve the problem but I would like to know about the causes of the lost of one archivelog. Many time the trace that does not exist has been backed the day before so I do not know why the rman need it again.
Here is the script I use to back up:
$ORACLE_HOME/bin/rman LOG=rman.log<<EOF >/dev/null
connect TARGET /;
sql 'alter system archive log current';
backup as compressed backupset check logical TAG "RMAN_REDOS" archivelog all delete input format 'SAVE';
backup current controlfile for standby format 'CONTROL';
When I check error, I see that this archived log still is on control file rman catalog and isn´t on +ASM 'cause it was saved already.
When I check rman 's log I see that the file was backed in a before backup.
Could you please notice me about the causes?
Do you have any suggestion for me?
