On this page:

After Axxon Next 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 Next Software Package).

Changing the gRPC API port

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 10. Creating system variable).

Changing the port range of the Server

To change the port range for a Server, use the Network settings utility (see Network settings utility).

Changing the PostgreSQL database port

In Axxon Next 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.

There are two ways to change it:

  1. Complete removal of Axxon Next and PostgreSQL with all data.
  2. Configuration changes.
Changing the PostgreSQL database port by removing Axxon Next completely

To do this:

  1. Remove Axxon Next without saving the configuration (see Deinstallation).
  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 (see Installation).
Changing the PostgreSQL database port in the configuration

If it is necessary to change the PostgreSQL database port and at the same time save the system and database configuration, then do the following:

  1. Run the command line as Administrator.

  2. Stop Axxon Next services:

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


  3. Stop PostgreSQL service:

    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:

    Note

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

    set CONFIG_PATH=C:\ProgramData\AxxonSoft\AxxonNext
    set InstallDir=C:\Program Files\AxxonSoft\AxxonNext
    cd "%CONFIG_PATH%\Config.local\config_repo\EventDatabase.0\"
    powershell -Command "(gc main.conf) -replace '<port>49998</port>', '<port>20110</port>' | Out-File -encoding ASCII main.conf"
    cd "%CONFIG_PATH%\Config.local\config_repo\"
    "%InstallDir%\bin\hg.exe" commit --verbose "--message=change DB port" --user "Manual change DB" -- EventDatabase.0/main.conf
    cd "%CONFIG_PATH%\Config.local\clone_config_repo\EventDatabase.0\"
    powershell -Command "(gc main.conf) -replace '<port>49998</port>', '<port>20110</port>' | Out-File -encoding ASCII main.conf"
    cd "%CONFIG_PATH%\Config.local\clone_config_repo\"
    "%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\AxxonNext\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:

    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"
    cd "%CONFIG_PATH%\Config.local\config_repo\"
"%InstallDir%\bin\hg.exe" commit --verbose "--message=change DB port" --user "Manual change DB" -- ObjectSearcher.0/main.conf
    cd "%CONFIG_PATH%\Config.local\clone_config_repo\ObjectSearcher.0\"
powershell -Command "(gc main.conf) -replace '<port>49998</port>', '<port>20110</port>' | Out-File -encoding ASCII main.conf"
    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\AxxonNext\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:

    cd "%CONFIG_PATH%\Config.local\config_repo\RealtimeRecognizer.0\"
powershell -Command "(gc main.conf) -replace '<port>49998</port>', '<port>20110</port>' | Out-File -encoding ASCII main.conf"
    cd "%CONFIG_PATH%\Config.local\config_repo\"
"%InstallDir%\bin\hg.exe" commit --verbose "--message=change DB port" --user "Manual change DB" -- RealtimeRecognizer.0/main.conf
    cd "%CONFIG_PATH%\Config.local\clone_config_repo\RealtimeRecognizer.0\"
powershell -Command "(gc main.conf) -replace '<port>49998</port>', '<port>20110</port>' | Out-File -encoding ASCII main.conf"
    cd "%CONFIG_PATH%\Config.local\clone_config_repo\"
"%InstallDir%\bin\hg.exe" commit --verbose "--message=change DB port" --user "Manual change DB" -- RealtimeRecognizer.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.

  12. If there is a main.conf file in the C:\ProgramData\AxxonSoft\AxxonNext\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:

    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""
    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
    cd "%CONFIG_PATH%\Config.local\clone_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"
    cd "%CONFIG_PATH%\Config.local\clone_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:

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


  14. Run the Axxon Next services:

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