After Axxon Next One is installed, you can change the port range for Servers, the gRPC API port number, and the PostgreSQL database port (see Ports used by the Axxon One Software Package).

...

To change the gRPC API port number, create an NGP_NATIVE_BL_PORT system variable, and set its value to the required port number (see Appendix 109. Creating system variable).

Changing the port range of the Server

...

Changing the PostgreSQL database port

In Axxon Next One 4.5.0, the default port of PostgreSQL database was replaced for 20110. If you upgrade your system from a previous version (see Update), the old port number 49998 is preserved.

...

1. Complete removal of Axxon Next One and PostgreSQL with all data.
2. Configuration changes.

Changing the PostgreSQL database port by removing Axxon

...

One completely

To do this:

1. Remove Axxon Next One without saving the configuration (see Removal).
2. Remove PostgreSQL.
3. Delete all folders with PostgreSQL.NGP in their names in the С:\Program Files\Common Files\AxxonSoft\ folder.
4. Delete the HKEY_LOCAL_MACHINE\SOFTWARE\PostgreSQL\ registry section.
5. Restart the computer.
6. Install Axxon Next One (see Installation).

Changing the PostgreSQL database port in the configuration

...

1. Run the command line as Administrator.

2. Stop Axxon Next One services:

   Code Block
   powershell -Command "get-service NGP_* | stop-service"

   
   

3. Stop PostgreSQL service:
   

   Code Block
   powershell -Command "get-service postgresql* | stop-service"

   
   

4. Open the postgresql.conf configuration file in the editor, located in the C:\Program Files\Common Files\AxxonSoft\PostgreSQL.NGP\Data folder.
5. Find the line port = 49998 and change the port value to 20110.
6. Save changes to the file.
7. Open the Registry Editor and go to the HKLM\SOFTWARE\PostgreSQL\Services\postgresql-9.5 section. The version number in the section name may differ from 9.5.
8. Change the value of the Port parameter from 49998 to 20110.

9. On the command line, run the following commands in sequence:

   Info
   title Note
   The first two commands use the default Axxon Next One installation paths (see Installation). If other paths are used, then it is necessary to change the commands.

   
   

   Code Block
   set CONFIG_PATH=C:\ProgramData\AxxonSoft\AxxonNextAxxon One

   
   

   Code Block
   set InstallDir=C:\Program Files\AxxonSoft\AxxonNextAxxon One

   
   

   Code Block
   cd "%CONFIG_PATH%\Config.local\config_repo\EventDatabase.0\"

   
   

   Code Block
   powershell -Command "(gc main.conf) -replace '<port>49998</port>', '<port>20110</port>' | Out-File -encoding ASCII main.conf"

   Code Block
   "%InstallDir%\bin\hg.exe" commit --verbose "--message=change DB port" --user "Manual change DB" -- EventDatabase.0/main.conf

   
   

   Code Block

   Code Block

   Code Block
   "%InstallDir%\bin\hg.exe" commit --verbose "--message=change DB port" --user "Manual change DB" -- EventDatabase.0/main.conf

   
   

10. If there is a main.conf file in the C:\ProgramData\AxxonSoft\AxxonNextAxxon One\Config.local\config_repo\ObjectSearcher.0 folder, and there is a <port>49998</port> parameter in this file, then run the following commands in sequence:
    

    Code Block
    cd "%CONFIG_PATH%\Config.local\config_repo\ObjectSearcher.0\" powershell -Command "(gc main.conf) -replace '<port>49998</port>', '<port>20110</port>' | Out-File -encoding ASCII main.conf"

    Code Block
    cd "%CONFIG_PATH%\Config.local\clone_config_repo\" "%InstallDir%\bin\hg.exe" commit --verbose "--message=change DB port" --user "Manual change DB" -- ObjectSearcher.0/main.conf

    If there is no main.conf file in the folder, or if the port parameter is missing in the file, then skip this step.

11. If there is a main.conf file in the C:\ProgramData\AxxonSoft\AxxonNextAxxon One\Config.local\config_repo\RealtimeRecognizer.0 folder, and there is a <port>49998</port> parameter in this file, then run the following commands in sequence:

    If there is no main.conf file in the folder, or if the port parameter is missing in the file, then skip this step.

12. If there is a main.conf file in the C:\ProgramData\AxxonSoft\AxxonNextAxxon One\Config.local\config_repo\VMDA2_DB.0 folder, and there is a <port>49998</port> parameter in this file, then run the following commands in sequence:
    

    Code Block
    cd "%CONFIG_PATH%\Config.local\config_repo\VMDA2_DB.0\" powershell -Command "(gc main.conf) -replace '<pg_port>49998</pg_port>', '<pg_port>20110</pg_port>' | Out-File -encoding ASCII main.conf""

    
    

    Code Block
    cd "%CONFIG_PATH%\Config.local\config_repo\" "%InstallDir%\bin\hg.exe" commit --verbose "--message=change DB port" --user "Manual change DB" -- VMDA2_DB.0/main.conf

    If there is no main.conf file in the folder, or if the port parameter is missing in the file, then skip this step.

13. Run the PostgreSQL service:
    

    Code Block
    powershell -Command "get-service postgresql* | start-service"

    
    

14. Run the Axxon Next One services:
    

    Code Block
    powershell -Command "get-service NGP_* | start-service"
