DB2 logs are full

Question

Hi All,
We install SRM system with DB2 9.1, We have using logarchmeth1. The log directory /db2/SID/log_dir is getting full every time.
We are taking full online backup including logs every week for the Development server.
Can i delete the logs in the log_dir..? as we are taking full online backup including logs. And we dont have tape to take backup of archive logs.
Please suggest..
Regards,
