EBU installation problems

We are using the folowing environment :

AIX         :  4.1.5
ADSM CLIENT :  2.1.0.6
ADSMConnect :  2.1.0.6
EBU         :  2.1.0.1.2
ORACLE       :  7.3.3

Installation of the software products, setting up EBU database and registering
target databases was OK, but when we tried to make a online backup with
EBU we get the folowing are messages (see below for full log file) :
