CONNX Data Integration Suite 14.8.0 | Adabas Event Replicator for LUW | Installation | Default Port Numbers and Firewall Considerations
 
Default Port Numbers and Firewall Considerations
The following table shows the default ports for different Adabas Event Replicator for LUW components:
Component Name
Default Port
CONNX Message Queue
9200
CONNX Replication Controller
9205
cnxepcfg (or cnxepcfg_64)
9207
CONNX data server for Adabas
6500
ADABCK - Adabas to Adabas replication only. Uses the CONNX data server.
6500
License Server
7501
If CONNX is installed in an environment where a firewall is present, these ports need to be opened.
Because Adabas Event Replicator for LUW is designed to work in a distributed environment, it is likely that components will be installed on different machines. If there is a firewall between the machines where the different components are installed, the ports for the components need to be open in the firewall. Here is a description for each port:
Port
Description
9200
This port is used by the CONNX Message Queue and must be open and allowed to accept connections from all machines where an Adabas Event Replicator for LUW component is installed. This includes the Replication Administration machine, the EP machine, and the Event Server (controller) machine.
9205
This port is used by the controller to accept connections from the EP. If the EP and the controller are not installed on the same machine, port 9205 on the controller machine must be open and allowed to accept connections from the EP machine. If there are multiple EP machines in the configuration, then port 9205 needs to be able to accept connections from each EP machine.
9207
This port is used by an EP helper process and is always running on the same machine as the EP. This port does not need to be opened in the firewall.
6500
This port is used by the CONNX listener (data server). While the data server is not a replication component, it is used in the replication process to access Adabas during the initial state process. The Replication Administrator also uses the dataserver to connect to the source Adabas database. The data server must be present on the EP machine and port 6500 must be open and allowed to accept connections from the machine where the controller is installed. In an Adabas to Adabas environment, the data server is responsible for moving data between the source and target instances of ADABCK during the initial state process.
7501
This port is used by the license server and must be open and allowed to accept connections from any machine where CONNX components are installed. This includes the EP, Controller, Replication Administrator, and any other CONNX clients running in the environment.
The following diagram illustrates the TCP/IP port assignments for a typical configuration with the Replication Administrator installed on System 1, the source Adabas database along with the EP installed on System 2 and the Controller along with the target database installed on System 3:
The Replication Administration communicates with the target database through the specific port for the target database, to the message queue through port 9200 and to the CONNX Adabas Data Server through port 6500. The event consumer uses port 9200 to communicate with the message queue, and the event producer uses port 9205 to communicate with the event controller.
In this example:
*System 1
*must open port 9200 and allow connections from System 3
*from any source port, it must be able to connect to System 2 on port 6500.
*from any source port, it must be able to connect to System 3 on port 9200 and the target database port
*System 2
*must open port 9200 and allow connections from System 3
*must open port 6500 and allow connections from System 1 and System 3
*from any source port, it must be able to connect to System 3 on port 9205
*System 3
*must open port 9200 and allow connections from System 1
*must open the target database port and allow connections from System 1
*must open port 9205 and allow connections from System 2
*from any source port, it must be able to connect to System 1 on port 9200
*from any source port, it must be able to connect to System 2 on port 6500 and 9200
*All Systems must be able to connect to the License Server (not depicted in the above diagram) on port 7501 from any source port.
*License Server (not depicted in the above diagram) must open port 7501 and accept connections from any system where CONNX components are installed.
This example depicts the target database on the same system as the Event Server (System 3). If the target databas is on a different system, the appropriate port will need to be open on that system and allow access from System 3 and System 1. Also, this example depicts Adabas Event Replicator for LUW with a relational database as the target. If the target database is another Adabas database, the Adabas Entire Network is required. In addition to the ports listed above, additional ports may need to be opened in the firewall. See the Adabas documentation for more details.
Note: 
In an environment where a firewall is present between the data server and any other system, the Data Server parameter CNXCONNECTBACK should be set to 0.
