Are there any possible reason RMAN generates some corrupt archive log files

Question

Dear all,
Are there any possible reason RMAN generates some corrupt archive log files?
Best Regards,

Answer 1

Because I try to perform daily backup at lunch time and found out it takes more than 1 hour had no any progress. Normally we take around 40 minus. The following is the log file:
RMAN> Run
2> {
3> CONFIGURE CONTROLFILE AUTOBACKUP ON;
4> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u03/db/backup/RMAN/%F.bck';
5> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 1 DAYS;
6> allocate channel ch1 type disk format '/u03/db/backup/RMAN/backup_%d_%t_%s_%p_%U.bck';
7> backup incremental level 1 cumulative database plus archivelog delete all input;
8> backup current controlfile;
9> backup spfile;
10> release channel ch1;
11> }
12> allocate channel for maintenance type disk;
13> delete noprompt obsolete;
14> delete noprompt archivelog all backed up 2 times to disk;
15>
16>
using target database controlfile instead of recovery catalog

allocated channel: ch1
channel ch1: sid=99 devtype=DISK
Starting backup at 31-MAR-09
current log archived
After that I go to archive log directory "/u02/oracle/uat/uatdb/9.2.0/dbs" and use ls -lt command to see how many archive logs and my screen just hang. After we found out that we cannot use ls -lt command to read arch1_171.dbf
archive log, the rest of archive logs able to use ls -lt command.
We cannot delete this file as well. We shutdown database abort and perform check disk...... and fix the disk error and then open database again. Everything seems back to normal and we can use ls -lt command to read arch1_171.dbf.
The strange problem is we have the same problem in Development and Production..... one ore more archive logs seems to be corrupted under the same directories /u02/oracle/uat/uatdb/9.2.0/dbs.
Does anyone encounter the same problem?
