oracle不建议在standby是non-exadata的情况下使用EHCC，具体可以参考下面文档

除了EHCC外，其他方面不会影响Exadata和Non-Exadata的dataguard组合。

How to check which object uses the HCC?

Please run the below SQL to query.

If the results show Query High, Query Low,Archive High and Archive Low, that indicates the object used the EHCC.

SQL>select s.owner,segment_name,s.bytes/1024/1024 t_size,compress_for

from dba_segments s,dba_tables t

where s.owner=t.owner and t.table_name=s.segment_name and compress_for is not null;

For example, an Exadata primary database using HCC can have a standby database deployed on a non-Exadata system that uses SUN ZFS or AXIOM storage (see My Oracle Support Note
413484.1 for limitations to support for heterogeneous Data Guard configurations).

In a second example where the primary database is on Exadata but HCC is not used, a standby database may be hosted on any third party storage and system (subject to the
heterogeneous support limitations defined in My Oracle Support Note
413484.1 ).
