This document describes the ports that are needed by Adabas LUW and Entire Net-Work LUW products to perform its processing and how they can be assigned. It covers the following topics:
The following table describes the ports that are needed by Entire Net-Work to perform its processing and any default ports assumed by Entire Net-Work. You should consider avoiding the use of these default port numbers for other applications.
| Software AG Product Component | Ports Needed | Default Port Number |
|---|---|---|
| Adabas Manager Communicator | One port is needed. | 4980 |
| Adabas Directory Server | One port is needed for Entire Net-Work requests to the Directory Server | 4952 (IANA port)
Note: |
| Adabas Manager | One port is needed for Adabas Manager administration tasks | dynamically assigned |
| Entire Net-Work Kernel | A port is needed for Kernel access by clients | dynamically assigned |
| A port is needed for Kernel access via connections (Entire Net-Work 7 or later) | dynamically assigned | |
| A port is needed for Kernel access via RDA connections (Entire Net-Work 2) | 7869 | |
| A port is needed for Adabas Manager administration of Kernels | dynamically assigned |
Software AG has registered port number 4952 with the Internet Assigned Numbers Authority (IANA) for use by the Adabas Directory Server. For more information about Directory Server port number specifications, read The Directory Server Port Number in the Software AG Directory Server Installation and Administration Guide. For information on changing the Directory Server port number for an Entire Net-Work installation, read Changing the Adabas Directory Server Port Number.
In general, there are no default port numbers assigned to Entire Net-Work Kernels or clients. These are dynamically assigned by Entire Net-Work when the Kernel or client is started, unless you specify a specific port or range of ports to use when you define the Kernel or client. If you set the port number to "0", the Entire Net-Work will dynamically assign a port.
Port numbers are dynamically assigned by Entire Net-Work when the Kernel or client is started, as follows:
Entire Net-Work searches for the first available port starting from port 49152 through 65535. (The starting search port number, 49152, is the IANA-recommended value from which to start.).
Once an available port number is found, it is assigned to the Kernel or client in its Adabas Directory Server entry.
While defining Entire Net-Work Kernels, you can also select a specific port or specify a range or list of port numbers that Entire Net-Work should search during the process in which it dynamically assigns a port to the Kernel:
To specify a specific port number, enter the number in the port number field when you define the Kernel.
To specify a range of port numbers that Entire Net-Work should search to dynamically assign a port, list the starting and ending ports in the port number field when you define the Kernel, separated by a dash (-). For example, a specification of "9010-9019" would cause Entire Net-Work to search for the first available port between and including port numbers 9010 and 9019.
To specify a list of port numbers that Entire Net-Work should search to dynamically assign a port, list the port numbers in the port number field when you define the Kernel, separated by commas (,). For example, a specification of "9010,9013,9015,9017,9019" would cause Entire Net-Work to search for the first available port from this list of ports, starting with port 9010 and working from left to right through the list.
You can, of course, combine search ranges and lists in a port number field. For example, a specification of "9010-9019,10020,10050-10059" would cause Entire Net-Work to search for the first available port first in the 9010-9019 range (inclusive), then port 10020, and finally in the 10050-10059 range (inclusive). The first available port that Entire Net-Work encounters would be used for the Kernel.
If no available port is found in a specified range or list, an error occurs.
For more information about adding Kernels, read Adding Kernel Configuration Definitions in the Entire Net-Work Server LUW Installation and Administration Guide.
If you need to change the Directory Server port number for your
installation, follow these steps:
Within the settings for Entire Net-Work Client and any client configurations definitions, change all specifications for the Directory Server port number to the new port number you want to use. Directory Server port numbers can be changed for Entire Net-Work Client and the client configurations using the Adabas Manager by changing the SAGXTSDSPORT parameter. See the Adabas Manager documentation for details.
Within the settings for Entire Net-Work Server and any Kernels definitions, change all specifications for the Directory Server port number to the new port number you want to use. These port numbers can be changed using the Adabas Manager by changing the SAGXTSDSPORT parameter. See the Adabas Manager documentation for details.
Shut down the Entire Net-Work Client service or daemon and the Entire Net-Work Server service or daemon, as appropriate. Be sure to shut down every Kernel associated with the server as well.
For information on shutting down the Entire Net-Work Client service or daemon, read Stopping Entire Net-Work Client in the Entire Net-Work Client Installation and Administration Guide. For information on shutting down the Entire Net-Work Server service or daemon, read Stopping Entire Net-Work Server in the Entire Net-Work Server LUW Installation and Administration Guide.
Shut down the Directory Server service or daemon.
For information on shutting down the Directory Server service or daemon, read Starting and Stopping the Adabas Directory Server, in the Software AG Directory Server Installation and Administration Guide.
Modify the Directory Server installation, as appropriate for the operating system. When prompted, change the Directory Server port number to the new port number you want to use.
Start up the Directory Server service or daemon, if it is not automatically started after its installation was modified.
For information on starting up the Directory Server service or daemon, read Starting and Stopping the Adabas Directory Server, in the Software AG Directory Server Installation and Administration Guide.
Start up the Entire Net-Work Client service or daemon and the Entire Net-Work Server service or daemon.
For information on starting up the Entire Net-Work Client service or daemon, read Manually Starting Entire Net-Work Client in the Entire Net-Work Client Installation and Administration Guide. For information on starting up the Entire Net-Work Server service or daemon, read Manually Starting Entire Net-Work Server in the Entire Net-Work Server LUW Installation and Administration Guide.
