hello,
I am not a DBA and if you have one in your company you may ask him more information about this oracle error but it seems that main error is
ORA-24005: Inappropriate utilities used to perform DDL on AQ table
all the other ones are just consequence of this one.
Does your "protect" account on oracle DB as correct privileges as described in Symantec documentation ?
It seems there is already lot of object in tablespace you want to use for DLP DB (may be due to previous failed installation) and script is not able to drop them.
If you cannot solve it, you could try to drop this tablespace and create a new one for your DB protect user.
regards.
