SAP and Oracle database backup failing after Netbackup Client upgrade from 7.6.1 to 7.7.3

Hi,

If its not a compatibility issue, did you check the comunication between master and client?

####################### From Master

<installpath>\veritas\netbackup\bin\admincmd\bptestbpcd

options:
-client xxxx -verbose (where xxxx is a clientname)
-client xxxx -debug

####################### From Client

-ip (master/media server IP address)
