Interoperating with Version 6.0.2 and later processes
The high availability manager supports multihomed hosts, which means that the product processes can communicate with each other even if they are running on different versions of the product. If you are running Version 6.0.2 and later processes that need to communicate with each other, you need to consider there are high availability manager-related issues.
开始之前
关于此任务
Special considerations
are required when Version 6.0.2 nodes interoperate with Version 6.0
and Version 6.0.1 nodes without Fix Pack 2 (6.0.1.2), because these
earlier versions do not contain high availability manager multihome
support. Version 6.0 and Version 6.0.1 processes do not recognize
an asterisk as a valid value in the DCS_UNICAST_ADDRESS host name
field. Therefore, these processes cannot connect to Version 6.0.2
processes that are configured with an asterisk in the DCS_UNICAST_ADDRESS
host name field. When Version 6.0.2 processes must interoperate with
Version 6.0 or Version 6.0.1 processes, the DCS_UNICAST_ADDRESS for
all Version 6.0.2 processes must be configured to use a value other
than an asterisk. This configuration is done by setting the host name
field in the DCS_UNICAST_ADDRESS endpoint to a host name or to a textual
IP address.
- If the host is configured to use a single IP address, a string host name, for example, myhost.mydomain, is sufficient.
- If the host is configured to use multiple IP addresses, then a textual IP address, for example, 192.168.0.2, is required.
As you add Version 6.0.2 nodes and create servers into a mixed-release cell, you must set the host name field of the DCS_UNICAST_ADDRESS for all processes on the new nodes, including the node agent, to one of the two values previously specified. You must then restart the Version 6.0.2 processes to pick up the new value.
To change the host name field for a process:

The condition
can be detected in one of the following ways:
- Version 6.0 and Version 6.0.1 processes log the following message:
HMGR0024W: An error was encountered while looking up the IP address for the host name of a core group member. The host name is * and the server name is myCell01\myCellManager01\dmgr. The member is excluded from the core group.
此消息指示核心组中另一进程的主机名为星号。
- 如果 V6.0 和 V6.0.1 进程未连接至 V6.0.2 进程,那么 V6.0、V6.0.1 和 V6.0.2 进程将形成单独的视图。要检测这些视图,请检查各个进程记录的
HMGR0218 消息。如果进程已连接,就会在所有进程中记录同一消息。具体地说,连接的进程具有相同的视图标识并且在视图中具有相同数目的进程。
HMGR0218I: A new core group view is installed. The core group is defaultCoreGroup. The view identifier is (8:0.spoletoCell01\ spoletoCellManager01\dmgr). The number of members in the new view is 2.
