sap online backup finished but did not delete archive logs file

[headbig]

I had sap with oracle database installed on aix 6.1. and I used nbu 7.0.1 sap agent to backup my sap data.
But after my job finished, i found that log files in /oracle/DEV/oraarch had not deleted.It was very big. each day had three to four files name with DEVarch1_******.dbf.

In sap_online_backup script file,there was a line like the following:

if [ $RETURN_STATUS -eq 0 ]
then

        timeStamp=`date '+%m%d%y%H%M%S'` ;
        br_out_file="/tmp/brarchive_out.${timeStamp}" ;
        CMD_LINE="$SAP_ENV brarchive -c -d util_file -sd > $br_out_file"

Why my online backup finished, the archive log have not deleted?

Depending on the database activity, archive files are created around the clock. Can it be the archive files are created after the online backup + archive ?

You can check /oracle/<sid>/saparchive/arch<SID>.log to see what files have been backuped.

It's solved. When the online backup is finished,the archive log will be backuped and deleted.
