1.2.1 Checking the prerequisites for installing JP1/AO

Before you install JP1/AO, check the requirements for the server on which JP1/AO will be installed (JP1/AO server) and the impact on other products.

Procedure

1. Log in to the JP1/AO server as a user with Administrator or root permissions, and then check the following items:

   • Check the memory size, hard drive size, and OS that are required to install JP1/AO. If the OS of the server on which JP1/AO will be installed is Linux, check the prerequisite libraries.

   • Confirm that the network environment uses the TCP/IP protocol.

   • Confirm that network transmission within the local host is not blocked.

     Note that the JP1/AO server cannot be installed and operated in an environment in which network transmission to and from the IP address "127.0.0.1" is blocked within the local host. Do not block communications in firewall settings.

   • Make sure that the language set in the OS of the host on which JP1/AO will be installed is the same as the language to be used in JP1/AO.

2. Check for installed products other than JP1/AO, and then perform the following tasks:

   • If Hitachi Automation Director or Hitachi Ops Center Automator are installed, uninstall it.

   • If JP1/OA, Hitachi Command Suite products, or Hitachi Ops Center products are installed, stop all JP1/OA, Hitachi Command Suite product, and Hitachi Ops Center product services.

     When JP1/OA, Hitachi Command Suite products, or Hitachi Ops Center products are installed on the JP1/AO server, Common Component is shared with JP1/AO. When you install JP1/AO, you must stop all JP1/OA, Hitachi Command Suite products, and Hitachi Ops Center products. Similarly, when you install JP1/OA, Hitachi Command Suite products, or Hitachi Ops Center products on the JP1/AO server, you must stop JP1/AO services.

3. Review the services and other programs that are running on the JP1/AO server, so that JP1/AO can be installed on the server.

   • Stop any security monitoring software, virus detection software, or process monitoring software.

     If such software is running, the installation of JP1/AO might fail.

   • When installing JP1/AO in Windows, a service related to JP1/AO cannot start if Startup Type for that service is set to Disabled, which causes installation to fail. Make sure that Startup Type for each service is set to Automatic or Manual.

     For details about the relevant services, see the information about JP1/AO services in the JP1/AO Administration Guide.

   • If the OS on the JP1/AO server is Linux, firewall exceptions are not automatically registered during the installation of JP1/AO. Register firewall exceptions according to the OS-specific procedure.

   • If other programs use Windows event logs, perform the following:

     - If the Event Viewer window opens, close it.

     - If the Computer Management window opens, close it.

     - Stop the event log monitoring program.

     If a program that accesses event logs is running during the installation of JP1/AO, the installation might fail.

   • If the OS on the JP1/AO server is Windows, close the command prompt before you install JP1/AO.

     If JP1/AO is installed with the command prompt open, the environment variables that you specified during the installation operation are not applied.
