After you install
Connect:Direct® for UNIX on
a shared file system, modify IBM® Connect:Direct parameters
to support a clustering environment. Install
Connect:Direct for UNIX on
a shared cluster file system to use it in a cluster environment. Complete
the following procedure to modify the configuration files for a cluster
environment:
- Modify the following parameters:
- In the initialization parameters file (initparm.cfg), set :comm.info=0.0.0.0;nnnn:\
where nnnn is the number of the listening port you defined during
installation.
- In the api.parms record of the NDMAPI configuration file (ndmapi.cfg),
set :tcp.hostname=logical_host_ip_name:\ where logical_host_ip_name is
the virtual address of the cluster.
- In the network map file (netmap.cfg), set :tcp.api=logical_host_ip_name;nnnn:\
where nnnn is the API port you defined during installation.
- In the network map file (netmap.cfg), set the outgoing
address parameter in the local.node record to specify the local host
IP name or address of the floating address to the following value.
The remote node will also use this value for network map checking.
:outgoing.address=(host name |nnnnnn.nnn):\ |
- Modify the following records in the network map file:
- Set :comm.info=logical_host_ip_name;1364:\ to configure the loopback
remote node record.
- Set tcp.max.time.to.wait to a value other than zero and less than
the value set in the resource group manager of the cluster software
to allow for clean shutdowns.
- In the same volume group as the installation file system,
create a user data file system that is shared by all cluster nodes.
