Oracle Database Discussions

Hi ,
I installed Oracle 11g in OEL Linux . OEL Linux is inside Oracle VM . I installed in another machine (OEL Linux inside Oracle VM) . In the other machine installed Weblogic 10.3.2 , SOA Suite and RCU . I've noticed connection problems and hangs since installation of RCU .Database listener gets down or hangs every time i try to connect with it . Installation took a lot of time (this was unusual ) but in the end was successful . When i start soa_server i see errors regarding ConnectionDeadSQLException and DataSource related , when i try lsnrctl status it hangs a lot and sometimes it stops by itself .I'm 100% sure that it's listeners problem (I've tested connection from other machines too). I'm attaching listener.ora file . Please help me cause this is really urgent for me
