Installing and uninstalling Netcool Impact Auto Start on UNIX/Linux

Netcool Impact Auto Start allows you to start Impact servers on system startup.

The following procedures describe how to install and uninstall Netcool Impact Auto Start.

Note: To perform the steps in this section, you must sign on as a system administrator with root access. This is because the location where the files are generated and their final locations is a file system set of directories that non-root users will not have access to add or edit.

Installing Impact Auto Start

To install Netcool Impact Auto Start on UNIX and Linux platforms that are not using systemd, use the following steps:

Open the command line prompt.
Login as root by typing:
su - root
Change to the following directory:
IMPACT_HOME/install/startup
Run the following command:
./install_autostart.sh
At the prompt, type Y
At second prompt, type Y to install autostartup for the jrexec server.
Note: For an Impact GUI server only, there is no prompt to install the JRExec startup.

Configuring Auto Start for Systemd

To create the script and services needed for auto start of Impact for use with systemd, you must use the create_systemd_startup.sh script. As the impact install user:

Change to the following directory:
```
IMPACT_HOME/install/startup
```
Run the following command:
```
./create_systemd_startup.sh
```
At the prompt, type Y
At the second prompt, type Y to install autostartup for the jrexec server.

This will create a new directory IMPACT_HOME/install/startup/init.d with the start scripts and service files. There will be up to three service files depending on the options and packages installed:
```
ncigui.service
ncijrexec.service
nci.service
```
As the root user, copy the desired service files from IMPACT_HOME/install/startup/init.d to /etc/systemd/system

As root, reload systemctl:
```
systemctl daemon-reload
```
As root, enable the services you copied to /etc/systemd/system:
```
systemctl enable nci
systemctl enable ncigui
systemctl enable ncijrexec
```

The list of services will depend on your installation.
