Hi fellows.
I'v performed a "cold cloning" from NT 8.0.5 to Linux 8.1.7.
Everything went off well, but every time I connect using sqlplus I get the following error:

----------
ERROR:
ORA-06553: PLS-707: unsupported construct or internal error [2603]

Error accessing package DBMS_APPLICATION_INFO
ERROR:
ORA-06553: PLS-707: unsupported construct or internal error [2603]
----------

It then connects normally.
Second error seems to be a missing package, whereas I don't know the reason for the first one.

I've already executed standard.sql as SYS, but am getting the same error.

What should I do??
Would it be better to do a full Export and Import instead of a "cold cloning".... ??
TIA
