Pre-Install Preparations

As part of installation of the server-side components, validate the prerequisites and then extract product package. Access the installation folder AssistEdgeAutomation.zip for Windows and AssistEdgeAutomation.tar.gz for Linux.

Server-Side Prerequisite Validation

This section discusses about the manual validation and installation process of server-side prerequisites.

File Archiver

To verify if 7.zip is installed:

In the Start menu, enter 7-zip, if already present it appears in the list of applications displayed.
If not found, download 7-zip, and install it on the given server from here.

CAUTION:

Default decompression of Windows fails to properly unzip files with longer path. Incorrect extraction leads to failure of installation; hence, it is recommended to use 7-zip for extraction of the installation folder.

Extracting Product Package

For Windows

For Linux

To extract AssistEdgeAutomation.zip:

Save the product package on local drive of your system.
Right-click the product package, point to 7-zip, and then extract the file.
Find AssistEdgeAutomation.zip folder, and then right-click the file.
Point to 7-zip and then click Extract to AssistEdgeAutomation\.
The AssistEdgeAutomation.zip is extracted.

CAUTION:

7-zip (or similar archiver) is used to perform extraction of installation

folder as default decompression of Windows

fails to properly unzip the files. Incorrect extraction

leads to the failure of

installation.

To extract AssistEdgeAutomation.tar.gz:
Run the tar xvf AssistEdgeAutomation.tar.gz command from the directory where you want to extract the files.

AssistEdge-ML.zip
Download and extract this file. Once extracted, navigate to AssistEdge-ML > runtime folder and copy the python folder inside the <Installation Directory>/AssistEdgeAutomation > runtime folder.

AssistEdge-ML.tar.gz
Download and extract this file. Once extracted, navigate to AssistEdge-ML > runtime folder and copy the python folder inside the <Installation Directory>/AssistEdgeAutomation > runtime folder.

AssistEdge-LowCode.zip
Download and extract this file. Once extracted, navigate to AssistEdge-LowCode > runtime folder and copy the tomcat folder inside the <Installation Directory>/AssistEdgeAutomation > runtime folder.

AssistEdge-LowCode.tar.gz
Download and extract this file. Once extracted, navigate to AssistEdge-LowCode > runtime folder and copy the tomcat folder inside the <Installation Directory>/AssistEdgeAutomation > runtime folder.

CAUTION:

The path where you are extracting product package should not contain any space in the parent folder names.

You also need to update the configuration files stored within the installation folder as per the deployment you wish to achieve.

In the AssistEdgeAutomation folder, access scripts folder and then update the following:

Deployment Properties - In this section, you need to update details of the system where you wish to install server-side components.
Component Properties – This section is applicable only if you wish to change the default settings that depends on the deployment architecture you intend to deploy. The properties of components are the advance configuration setting of AssistEdge RPA.
Server Properties – In this section, you need to update server properties such as details related to cluster, ML and so on.

Deployment Properties

The deployment.properties file is used for storing and retrieving deployment runtime behavior. You need to update the file with details of the server you want to install AssistEdge RPA on.

To update deployment.properties file:

Access <Installation Directory>/AssistEdgeAutomation > scripts > app > install > config folder.
Locate the deployment.properties file and edit the below mentioned properties:

Name of Property

Description

WEB

Signifies the various parameters of the UI components such as hostname of the proxy server/load balancer to which it connects, computer name of the server where the components of the UI components server are installed, and the port number of the server.
All the components are accessed using this hostname only. For example, defining ae-dev as proxy server hostname while using ae-dev.ad.com to access the component post installation may lead to multiple errors.
Default value is set to- localhost COMPUTERNAME 8443.

In localhost, enter hostname of the proxy server or the load balancer, whichever is applicable
In COMPUTERNAME, enter machine name of the given server where you wish to install the UI components

Update port number of the UI components if you wish to use a different port for installation.

APP

Signifies the various parameters of the backend components such as hostname of the proxy server/load balancer to which it connects, computer name of the server where the components of the app server are installed, and the port number of the server.
All the components are accessed using this hostname only. For example, defining ae-dev as proxy server hostname while using ae-dev.ad.com to access the component post installation may lead to multiple errors.
Default value is set to- localhost COMPUTERNAME 8443.

In localhost field, enter hostname of the proxy server or the load balancer, whichever is applicable
In COMPUTERNAME field, enter machine name of the given system where you wish to install the backend components

Update port number of the backend components if you wish to use a different port for installation.

DATABASE

Signifies the name/instance of the database server where AssistEdge RPA database gets created/used. It also indicates the type of database used such as SQL or Oracle.

For SQL, default value is set to- DATABASE DATABASE-HOSTNAME SQL 1433.

In the DATABASE-HOSTNAME field, enter the hostname name of the SQL database server
Update port number of the configured SQL database server

For Oracle, enter the values in the given syntax- DATABASE [HOST] ORACLE [PORT].

In the HOST field, enter the hostname of the Oracle database server
In the PORT field, enter port number of the Oracle Database server

LOWCODEDATABASE (Optional)

Signifies the name/instance of database server where LowCode Database is created.

By default, this line is commented and LowCode tables are created in AssistEdge database. Uncomment this line if LowCode database should be separate.

NOTE:

For creating a new database for LowCode use the ae createdb command. Ensure to create LowCode database before starting LowCode.

It also indicates the type of database used such as SQL or Oracle

For SQL, default value is set to- LOWCODEDATABASE DATABASE-HOSTNAME SQL 1433.

In the DATABASE-HOSTNAME field, enter the hostname name of the SQL database that you created for AE
Update port number of the configured SQL database server

NOTE:

If the System Admin user wants to create the database for SQL with Windows authentication, then disable the sysadmin role access from the server role tab in the Microsoft SQL Server Management Studio or use different user credentials to create the database.

For Oracle, enter the values in the given syntax- LOWCODEDATABASE [HOST] ORACLE [PORT].

In the HOST field, enter the hostname of the Oracle database Server
In the PORT field, enter port number of the Oracle Database Server

For Postgres, enter the values in the given syntax- LOWCODEDATABASE [HOST] POSTGRES [PORT].

In the HOST field, enter the hostname of the Postgres database server
In the PORT field, enter port number of the Postgres database server

The deployment properties are updated.

NOTE:

On Linux if you wish to deploy on port 443 (any port number with value less than 1000) then deploy it on the default port 8443 and use the TCP routing to route traffic from 443 to 8443. The sample command is:
sudo iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 8443.

Component Properties

The component.properties file defines whether a component runs on the WEB server or the APP server.

The properties of a component are pre-defined within component.properties file. You can overwrite this property by changing web to app and vice versa.

NOTE:

You should not modify or remove the component name, else, the installation fails.

To Update component.properties File:

Access <Installation Directory>/AssistEdgeAutomation > scripts > app > install > config folder.
Find component.properties file, right click and then click Edit. The component.properties file opens as shown below.
Update the below properties to configure according to your deployment and then Save the file:
