Shared Pool problem

I just finished re-organising a server, with two databases.

One database is fine, the other has major problems with the data = dictionary
I think.

I can compile most of the views, except all_tab_columns, = all_tab_comments,
and all_col_comments.

Although all the other views compile, many of the data dictonary views = will
not run.

Even when I log in as myself (with DBA role) or as SYSTEM, I can't = query
v$sga, but if I log in as SYS I can query it no problem.

There is plenty of free space in the Shared Pool, according to = v$sgastat.

I am getting a number of ORA-600 errors:

Any ideas?
