In the oem "view backup report" seems to hang when selecting one of the backups of db hosted on exadata system. in meantime oem waits for query
completion involving one of v$backup*summary views.  This problem can be replicated in sqlplus:

sql> set timing on;
sql> select count(1) from v$backup_spfile_summary;
count(1):1, Elapsed 00:05:05.41

similar case for v$backup_archivelog_summary

sql> select count(1) from v$backup_archivelog_summary;
count(1):1, Elapsed 00:17:32.62
