Adabas Cluster 7.1.1 | From Project to Production | How to Set Up the Adabas Cluster | Adabas Server Configuration
 
Adabas Server Configuration
This table provides an overview of the Adabas nucleus parameters that are available to support the cluster interface:
Parameter
Description
CLUSTER_PORT
The TCP/IP port for intra-cluster communication.
CLUSTER_URL
Specify all possible cluster nodes, in the form gcomm://<node1 or ip:port>,<node2 or ip2:port>,<node3 or ip3:port>. Not necessary for the first node of a cluster.
CLUSTER_ OPTIONS
Allow additional parameter settings. For more information, see Parameters and Environment > Additional Provider Library Parameters.
CLUSTER_SST_PORT
TCP/IP port for State Snapshot Transfer. The default is to pick up a free number of the dynamic port range. This is mandatory, in case of firewall restrictions.
CLUSTER_IST_PORT
TCP/IP port for Incremental State Transfer. The default is to pick up a free number of the dynamic port range. This is mandatory, in case of firewall restrictions.
CLUSTER_BOOTSTRAP
If set, CLUSTER_URL setting will be ignored during startup.
CLUSTER_DONOR_NAME
The node name which should transfer data (IST or SST) to a joining node (optional).
CLUSTER_LOG_LEVEL
The maximum log level of cluster messages: FATAL|ERROR|WARN|INFO|DEBUG (optional, the default is INFO).
CLUSTER_NODE_NAME
The cluster node name (optional, the default is <HOSTNAME>-<CLUSTER_PORT>).
CLUSTER_PUBLIC_HOST
External representation of the ADATCP host - Public IP address or name (optional).
CLUSTER_PUBLIC_PORT
External representation of the ADATCP port - Port forwarding (optional).
To support Client Failover (High Availability - from the application point of view) in the cluster, the following parameter settings are required:
Parameter
Description
ADATCP
Enable the TCP/IP receiver.
PORTNUMBER
The TCP/IP port where the database listens for client connections.
SSLPORTNUMBER
The SSL port where the database listens for SSL client connections.
Client access is available using native TCP/IP and/or SSL connections. If the SSLPORTNUMBER parameter is set, the cluster node will only provide SSL communication to the clients, regardless of the setting of the PORTNUMBER parameter. It is possible to operate the cluster in mixed mode.
