Configure a core group transport
When we configure a core group, we can specify the type of network transport that we want the high availability manager to use for network communications.
Complete the following actions before starting to configure a core group transport.
- Review the content of the topic Core group transports.
- Confirm that all node agents in the core group are running.
- Determine which transport type is appropriate for the core group.
Change the transport setting for a core group if the current transport type does not meet our needs. For example, we might need to increase security, we might want to maximize replication throughput, or a core group might need to use the core group bridge service.
If a core group needs to use the core group bridge service, select Channel framework as its transport mechanism. If we select Unicast, we might receive error message CHFW0029E, which indicates that the transport chain was not initialized because the address was already in use.
Change the core group transport for a core group
- In the administrative console, click...
- Servers > Core Groups > Core group settings > [core group | New]
- Under Transport type, select the type of transport to use for this core group.
Deprecated feature: We can select one of the following types of transports. However, if possible, select Channel framework because support for unicast transports is deprecated.depfeat
- Channel framework is the default transport type, and is a flexible point-to-point transport. If we choose this transport type, we must also select one of the transport chains listed in the Transport chain field.
- If we select DCS, the high availability manager performs related network communication over non-secure sockets.
- If we select DCS-Secure, the high availability manager performs related network communication over SSL encrypted sockets.
- Unicast, is a point-to-point transport over standard non-secure operating system-level TCP/IP network connection facilities.
- Channel framework is the default transport type, and is a flexible point-to-point transport. If we choose this transport type, we must also select one of the transport chains listed in the Transport chain field.
- Click Synchronize changes with nodes> OK.
- Select Synchronize changes with nodes> Save again.
- Restart the servers containing core group members.
The new transport values are in effect after the servers restart.
