Changing the Default Ports with Offset¶

When you run multiple runtimes on the same server or virtual machines (VMs), you must change their default ports with an offset value to avoid port conflicts. An offset defines the number by which all ports in the runtime (e.g., HTTP/S ports) are increased.

For example, if the default HTTP port is 9763 and the offset is 1, the effective HTTP port changes to 9764. For each additional MWARE product instance running on the same machine, you set the port offset to a unique value.

There are two ways to set an offset to a port: Update the server configurations, or pass the port offset during server startup. See the instructions given below to port offset the three runtimes of MWARE ESB.

Before you begin¶

See the complete list of default ports in all the ESB components.

Note that most of the runtime ports change automatically based on the offset you specify here.

Changing the default API-M ports¶

The default port offset in the MWARE ESB runtime is 0. Use one of the following two methods to apply an offset to the API-M runtime.

Update the server configurations¶

Stop the API-M server if it is already running.
Open the <API-M-HOME>/repository/conf/deployment.toml file.
Uncomment the offset parameter under [server] and set the offset value.
Format
```
[server]
offset=<offset_value>
```
Example
```
[server]
offset=1
```
Restart the server.

Pass the port offset during server startup¶

Stop the API-M server if it is already running.

Restart the server with the -DportOffset system property.

Linux/Mac OS

Format

./api-manager.sh -DportOffset=<offset_value>

Example

./api-manager.sh -DportOffset=3

Windows

Format

api-manager.bat -DportOffset=<offset_value>

Example

api-manager.bat -DportOffset=3

When you offset the server's port, it automatically changes all ports.

Changing the default MI ports¶

The default port offset in the ESB Micro Integrator runtime is 10. Use one of the following two methods to apply an offset to the Micro Integrator runtime.

Tip

The internal offset of 10 is overriden by this manual offset. That is, if the manual offset is 3, the default ports will change as follows:
- 8290 -> 8283 (8290 - 10 + 3)
- 8253 -> 8246 (8253 - 10 + 3)
- 9164 -> 9157 (9164 - 10 + 3)
Note that if you manually set an offset of 10 using the following method, you will get the same default ports.

Update the server configurations¶

Stop the MI server if it is already running.
Open the <MI_HOME>/conf/deployment.toml file.
Uncomment the offset parameter under [server] and set the offset value.
Format
```
[server]
offset=<offset_value>
```
Example
```
[server]
offset = 3
```
Restart the server.

Pass the port offset during server startup¶

Stop the MI server if it is already running.

Restart the server with the -DportOffset system property.

Linux/Mac OS

Format

./micro-integrator.sh -DportOffset=<offset_value>

Example

./micro-integrator.sh -DportOffset=3

Windows

Format

micro-integrator.bat -DportOffset=<offset_value>

Example

micro-integrator.bat -DportOffset=3

Changing the default EI Analytics ports¶

If required, you can manually change the HTTP/HTTPS ports in the deployment.yaml file (stored in EI_ANALYTICS_HOME/conf/server folder) as shown below.

Note

With the default internal port offset, the effective port is https_port + 1.

HTTPS Port

wso2.transport.http:            
listenerConfigurations:
-
    id: "msf4j-https"
    host: "0.0.0.0"
    port: https_port
    scheme: https

HTTP Port

wso2.transport.http:
listenerConfigurations:
-
  id: "default"
  host: "0.0.0.0"
  port: http_port

Changing the default SI ports¶

The default port offset in the ESB Streaming Integrator (SI) runtime and the SI Tooling runtime are 0 and 3 respectively. Setting a port offset changes the thrift, binary, and management ports of the SI runtimes.

Follow the steps given below.

Open the deployment.toml file of the SI runtime or the SI Tooling runtime (stored in the <SI_HOME>|<SI_TOOLING_HOME>/conf/server/deployment.yaml directory).

Update the port offset parameters in the following configurations:

SI runtime

# Carbon Configuration Parameters
wso2.carbon:
    # value to uniquely identify a server
id: wso2-si
    # server name
name: ESB Streaming Integrator
    # server type
type: wso2-si
    # ports used by this server
ports:
    # port offset
    offset: 0

SI Tooling runtime

  # Carbon Configuration Parameters
wso2.carbon:
    # value to uniquely identify a server
id: wso2-si
    # server name
name: ESB Streaming Integrator Tooling
    # ports used by this server
ports:
    # port offset
    offset: 3

What's Next?¶

You need to restart the server for these changes to take effect.
