Setup

Preparation

General

You must be administrator of the web server. Using a local administrator account is recommended. You must know:

The physical path on the web server where the WorkflowGen web application will be installed
The physical path on the web server where WorkflowGen Windows services will be installed
The URL of the web server where WorkflowGen will be installed
MS SQL Server database:
- the name of the MS SQL Server
- the credentials of the SA account
- the file path of the SQL Server database files on the SQL server machine
Oracle database:
- an existing Oracle data source name
- the credentials of the database user account that has creation permission on the specified Oracle instance (see the next section for Oracle database installation parameters)
The name or IP address of the SMTP gateway (we recommend using the IIS SMTP gateway; see SMTP Notifications)
The default sender email address for notifications
The authentication method you want to use for WorkflowGen web applications

Requirements for installation on Oracle databases

WorkflowGen and Oracle 10g on the same server

National and Database character sets are both UTF-8
Oracle Database 10g Release 2 (10.2.0.3/10.2.0.4) Standard

WorkflowGen and Oracle 10g on separate servers

National and Database character sets are both UTF-8
Oracle Server: Oracle Database 10g Release 2 (10.2.0.3/10.2.0.4) Standard
WorkflowGen Server: Oracle Database 10g Client Release 2 (10.2.0.3)

WorkflowGen and Oracle 11g on the same server

National and Database character sets are both UTF-8
Oracle Database 11g Release 1 (11.1.0.6.0) Enterprise with Client software installed

WorkflowGen and Oracle 11g on separate servers

National and Database Character Set are both UTF-8
Oracle Server: Oracle Database 11g Release 1 (11.1.0.6.0) Enterprise
WorkflowGen Server: Oracle Database 11g Release 1 Client (11.1.0.6.0)

WorkflowGen and Oracle 12c on the same server

National and Database character sets are both UTF-8
Oracle Database 12c Release 1 (12.1.0.2.0) Standard

WorkflowGen and Oracle 12c on separate servers

National and Database character sets are both UTF-8
Oracle Database 12c Release 1 (12.1.0.2.0) Standard
WorkflowGen Server: Oracle Database 12c Release 1 (12.1.0.2.0) Client for Microsoft Windows

Authentication method

Check that the SQLNET.AUTHENTICATION_SERVICES parameter of DRIVE:\OraHome\network\ADMIN\SQLNET.ORA is set to NONE. This file is located on your web server.

Create a new tablespace (if WorkflowGen is set up on a blank tablespace)

In DBA studio or from SQL Plus, create a new tablespace called WFGEN with a minimum file size of 100 MB.
Once the tablespace is created, you should specify the Database and National character sets to UTF-8.
Create a user account with the following settings:
- Temporary and default tablespace: WFGEN
- Role: DBA or a more restrictive access. Initially, the user must have creation rights on the structure schema (tables, index, constraints, etc.). However, once the structure is created, only read/write rights are necessary.

Recommended Oracle performance configurations

Optimizer mode

To improve WorkflowGen database performance, check your database optimizer mode. If optimizer_mode is set to choose (the default in Oracle 9i and 10g), you have to frequently (weekly, for example) ANALYZE all the tables of your databases. This operation will generate statistics used by the optimizer to select the best mode (RULE instead of all_rows) to run an SQL query. Another solution is to set the optimizer mode to RULE.

System tables optimization

The System.Data.OracleClient provider used by WorkflowGen generates SQL instructions against some system tables (all_synonyms, all_cons_columns, and all_constraints). When those tables contain a lot of records (such as when WorkflowGen database shares the same Oracle instance with other databases), performance can be affected when launching or completing a request or action.

One way to minimize issues with response times when launching new requests or actions is to redirect these SQL instructions to local scope views/tables, which are filtered copies of these system tables. These changes are transparent to WorkflowGen.

To do this, run the SQL instructions below (replacing WFGEN_USER with your owner name) against your WorkflowGen database. (If the database owner has other tables used by other applications, you can still apply this procedure if those tables don’t use synonyms.)

Note: We suggest dropping these existing views and tables (all_synonyms, all_cons_columns, and all_constraints) from your database before each WorkflowGen version upgrade, then recreating them after completing the upgrade procedure.

create or replace force view WFGEN_USER.all_synonyms (owner, synonym_name, table_owner, table_name, db_link) as select null, null, null, null, null from dual;

create table WFGEN_USER.all_cons_columns as select * from sys.all_cons_columns where owner = 'WFGEN_USER';

create table WFGEN_USER.all_constraints as select owner, constraint_name, constraint_type, table_name, r_owner, r_constraint_name, delete_rule, status, deferrable, deferred, validated, generated, bad, rely, last_change, index_owner, index_name, invalid, view_related from sys.all_constraints where owner = 'WFGEN_USER'

WorkflowGen setup (PowerShell installation)

The following procedure applies to the setup using the WorkflowGen PowerShell installation, which is compatible with MS SQL Server (via SQL Server authentication), Windows Server 2012 R2, Windows Server 2016, and Windows 10. For Oracle database and/or other operating systems, use either the InstallShield Wizard installation procedure or the manual installation procedure.

You'll need an active internet connection to perform this installation unless all of the dependencies have been downloaded by running the script with the -DownloadOnly script flag.

Notes

By default, the PowerShell installation will always install the latest version of WorkflowGen. To install previous versions of WorkflowGen, replace the download URL of the latest manual installation pack (located in scripts\settings.json under WFGManualZipPath) with the WorkflowGen version number in the x-x-x format; for example, to download WorkflowGen version 7.4.0, the URL would be http://download.workflowgen.com/product/7-4-0/manual.zip.
The PowerShell installation will also install Node.js version 6.11.5, iisnode, and IIS Url Rewrite.

Installation

Open config.json in a text editor and configure the parameters for your installation of WorkflowGen (see Configuration parameters below for information on each parameter).
Open a PowerShell instance as Administrator.
Run .\install.ps1 (with the optional script flags listed in Optional parameters below, if desired).

Notes

Ensure that the PowerShell Execution Policy is correctly set (see https://technet.microsoft.com/en-us/library/ee176961.aspx). If you want to avoid modifying the Execution Policy, you can bypass it by running the WorkflowGen installation script as follows: PowerShell.exe -ExecutionPolicy Bypass -File .\install.ps1.
Clicking on the shell while it is running will pause the output; you can change this option in the PowerShell options, or press ENTER to resume the output (this will not pause the script, which will continue to run in the background).

Optional PowerShell script flags

Parameter

Description

DownloadOnly

Example: .\install.ps1 -DownloadOnly This option will terminate the scripts after all necessary packages have been downloaded. This is useful if you want to install WorkflowGen on a network that's not connected to the internet.

SkipParamInput

Example: .\install.ps1 -SkipParamInput This option will skip the prompts to review the parameters before launching the installation script, for example if you want to run the install.ps1 script via another script.

PowerShell installation configuration parameters

Parameter

Description

LicenseType

Possible values: free or full (default: free) Describes the type of license under which you're installing WorkflowGen: full will populate the SerialNumber parameter in the "web.config" file; free will include the free license and its EULA. Note: If you're installing under the full WorkflowGen license, you'll need to manually copy your license file to the WorkflowGen \bin folder (e.g. C:\Inetpub\wwwroot\wfgen\bin).

SerialNumber

If you're installing under the full license, enter the serial number you were provided with

WebAppPath

The physical location where the WorkflowGen site will be located (default: C:\Inetpub\wwwroot\wfgen) Note: This path must end with \wfgen.

ServicesPath

The physical location where the WorkflowGen services will be installed (default: C:\Program Files\Advantys\WorkflowGen\Services)

NodeJSPath

The physical location where Node.js will be installed; this package is required for WorkflowGen features such as GraphQL and webhooks

SQLServerInstance

The name or location of the SQL Server database instance Note: If the database server is the same as the WorkflowGen application server, you can use (local).

SQLLoginID & SQLPassword

The login credentials used exclusively for the creation of the WorkflowGen database; these must have the appropriate access level Note: These parameters can be left empty if the SQLServerInstance provided already has a fully-functional (including SQL login users) and up-to-date WorkflowGen database.

DBName

The name of the WorkflowGen database to use or create (default: WFGEN) Note: If the database name is already in use, no database will be created, and the installation will assume that the database provided is fully functional (including SQL login users) and up-to-date.

DBFilePath & DBLogPath

The physical location where the new database will be created (only applicable when creating a new database); leaving this path empty will create the database in the default path in the environment Note: If these parameters are specified, the identity for SQL Server must also have permission for this folder.

DBLoginID & DBPassword

Standard database user (with read and write permissions) used by the WorkflowGen application (default: WFGEN_USER); the database user is created only if a new database is created Note: If you're using an existing database, these parameters will be used in the "web.config" connection string, so make sure that they match the existing database user and login. If you're creating a new database, make sure that this login is not already used (by another database, for example).

IISSiteName

The name of the IIS website under which the WorkflowGen application will exist; an IIS website will be created if it does not already exist (default: WorkflowGen)

IISAppPoolName

The IP address to be bound to WorkflowGen; the * value represents all unassigned IP addresses (default: *)

IISPort

The TCP/IP port for WorkflowGen (default: 80)

IISAuthentication

Specifies which IIS authentication mode to use for the initial WorkflowGen installation; the possible values are Windows, WorkflowGen, and Basic WorkflowGen uses WorkflowGen's custom authentication module, which stores the credentials in the WorkflowGen database. If this option is selected, the initial password for the account specified in WFGAdminUsername will be set to Passw0rd! and should be changed immediately. Basic uses IIS authentication based on the current Windows setup. With this option, you can create a new Windows user (WFGAdminUsername) with a specific password, or use an existing Windows account. Windows uses IIS authentication based on the current Windows setup, similar to Basic; however, you'll need to be logged in as the account specified in WFGAdminUsername

WFGAdminUsername & WFGAdminPassword & WFGAdminDomain

WorkflowGen's first administrator account (default: wfgen_admin); depending on the authentication method, this may require a corresponding Windows account. A password is only required if the account is being created.

WebsiteURL

The URL where WorkflowGen will be accessible; this value is populated in the "web.config" (default: http://localhost/wfgen)

SMTPServer

The location of the SMTP server for WorkflowGen; this value is populated in the "web.config" (default: smtp.mycompany.com)

DefaultEmailSender

The default email used as the sender for WorkflowGen notifications; this value is populated in the "web.config" (default: workflowgen@mycompany.com)

Important notes

In JSON format, backslashes (\) must be escaped as follows:
```
{
   "param" : "C:\\valid\\windows\\path"
}
```
You can abort the script at any point by pressing CTRL+C. If this is done during a download or extraction process, the folders created might need to be deleted (e.g. \package\); otherwise, the script will detect their presence and assume that they are complete.

WorkflowGen setup (InstallShield Wizard installation)

The following procedure applies to the setup using the WorkflowGen InstallShield Wizard installation pack. To start the installation wizard, double-click on the setup execution file and follow the instructions on the screen. The installation can be cancelled at any time by clicking Cancel.

The InstallShield Wizard will perform the following actions:

Install the web application.
Install the Windows Services.
Note: The user or identity used to run WorkflowGen Windows Services must be an administrator, be part of the Administrators group, or be a Windows system account (such as "Local System"). You can check this by running "services.msc".
Create the SQL Server database structure and contents and associated database user account if MS SQL Server is chosen.
Create the Oracle database structure and contents if Oracle is chosen.
Create the Windows NT or Domain user account (default WorkflowGen administrator).
Create a log file in the directory where the WorkflowGen setup execution file is located. In case of any problems, the error will be detailed in it. We recommend launching the setup program from your web server.

For the manual installation procedure, skip to WorkflowGen setup (manual installation).

Welcome screen

Click Next to continue. The setup program will suggest that you stop IIS services as well as any anti-virus software during the installation.

Define the physical path for the WorkflowGen services folder. By default, the suggested physical path is DRIVE:\Program Files\Advantys\WorkflowGen.

Note: This installation will overwrite your existing WorkflowGen services if you already have another version of WorkflowGen installed on the same server. If you want to keep your previous WorkflowGen services, we suggest you choose another installation folder for version 7 (e.g. DRIVE:\Program Files\Advantys\WorkflowGen v7). When this setup is completed, see the Configuring multiple instances of WorkflowGen section for instructions on how to re-install the previous services on the same server.

Specify the Windows services files and folder path. Make sure to include the \Advantys\WorkflowGen sub-folders.
Click Change to choose another destination folder. A dialog box will open to let you choose another destination folder.
Click Next to continue.

Database creation

Select either MS SQL Server or Oracle, then click Next.

Important: WorkflowGen does not support case sensitive collation, so you must set up the database to be case insensitive to avoid errors.

MS SQL Server configuration

Important: If you choose to create a new database using an existing database name all data will be erased and overwritten with an empty database. To prevent unintentional data loss, make sure to choose a unique name for the database. As well, you should back up your existing database before proceeding with the installation.

MS SQL Server requirements

You cannot use the InstallShield Wizard with SQL Server in Windows Authentication mode only.
The SQL Server must support SQL authentication. Enable this security setting in your SQL Server configuration if it isn’t already enabled.

MS SQL Server authentication

The application will ask for information about the parameters of the connection to the MS SQL Server database.

WorkflowGen Administrator account setup

WorkflowGen requires a valid Windows NT or Active Directory account. This account will be used by the WorkflowGen Administrator, but it is not necessary to define it as a NT or Active Directory Administrator.

You can use an existing user account or create a new user account with the name "Domain\wfgen_admin".
If you use a different account name other than "wfgen_admin", then you MUST change the "WorkflowGen Administrator" username in the WorkflowGen database. To do this, in the Users table, find the record with the column "USERNAME" value "wfgen_admin", then change it to your custom user account name.

WorkflowGen web configuration

Open and edit the "DRIVE:\Inetpub\wwwroot\wfgen\web.config" WorkflowGen web configuration file.
Update the database connection string:
- MS SQL Server: <add name="MainDbSource" connectionString="Data Source=localhost;Initial Catalog=WFGEN;User ID=WFGEN_USER;Password=Admin123!;" providerName="System.Data.SqlClient" />
- Oracle: <add name="MainDbSource" connectionString="Data Source=WFGEN;User ID=WFGEN_USER;Password=Admin123!;" providerName="System.Data.OracleClient" />
Update the "WorkflowGen Administrator" username to allow access to the configuration panel (e.g. ).
Set an SMTP server or SMTP gateway name (e.g. <add key="ApplicationSmtpServer" value="smtpservername" />).
Update the application URL (e.g. <add key="ApplicationUrl" value="http://yoursite/wfgen" />).
Set a default email sender for the notification (e.g. <add key="EngineNotificationDefaultSender" value="workflowgen@company.com" />).

WorkflowGen Windows Services installation

Notes

The user or identity used to run WorkflowGen Windows Services must be an administrator, be part of the Administrators group, or be a Windows system account (such as "Local System"). You can check this by running "services.msc".
If you have specified a custom installation path for the services, you will need to update the path inside the "DRIVE:\Program Files\Advantys[Custom WorkflowGen]\Services\bin\winsvc-install.cmd" script (e.g. %windir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe /i "C:\Program Files\Advantys\[Custom WorkflowGen]\Services\bin\WfgDirectoriesSyncService.exe").
If you are installing these services along with previous WorkflowGen services on the same server, you will need to provide a new service name (e.g. WorkflowGenEngineServiceV7) for both the Engine and Directory services in their configuration files ([WfgWorkflowEngineService.exe].config: <add key="ServiceName" value="WorkflowGenEngineServiceV7"></add>) and script files (winsvc-install.cmd: Rename all [WorkflowGenEngineService] to [WorkflowGenEngineServiceV7]). (See the Configuring multiple instances of WorkflowGen section for information and instructions on how to configure multiple WorkflowGen services on the same server.)

Installation

Open and edit the "DRIVE:\Program Files\Advantys\WorkflowGen\Services\bin\WfgWorkflowEngineService.exe.config" Engine service configuration file.
Update the WorkflowGen web configuration path (e.g. <add key="WebConfigPath" value="DRIVE:\inetpub\wwwroot\wfgen\web.config" />).
Open and edit the "DRIVE:\Program Files\Advantys\WorkflowGen\Services\bin\WfgDirectoriesSyncService.exe.config" Directory Synchronization service configuration file.
Update the WorkflowGen web configuration path (e.g. <add key="WebConfigPath" value="DRIVE:\inetpub\wwwroot\wfgen\web.config" />).
Note: "WfgWorkflowEngineService.exe " and "WfgDirectoriesSyncService.exe" might be blocked. To check this, right-click on them and choose Properties. If the Security section is displayed at the bottom of the General tab, these executables have been blocked; in this case, click Unblock.
Run "DRIVE:\Program Files\Advantys\WorkflowGen\Services\bin\winsvc-install.cmd" as Administrator.

Application files access configuration

File permissions

File permission settings can be configured as follows for the WorkflowGen application identity:

DRIVE:\Inetpub\wwwroot\wfgen: Modify all.

According to your authentication method (see Security), the WorkflowGen application identity can be:

The corresponding Windows users
The ASP.NET or IIS application pool identity

Configuring IIS

Creating the application pool

It is recommended that WorkflowGen be isolated from other applications by creating its own application pool and associating all declared applications with the new application pool.

Note: Domain users and the Windows accounts used to run the WorkflowGen IIS application pool and Engine service must have read and write permissions for the \wfgen\app_data folder.

Configuring the WorkflowGen root website to auto-redirect to the `wfgen` web app

If you would like your WorkflowGen root website (e.g. https://server) to auto-redirect to the https://server/wfgen web app , follow the procedure below.

Make sure the URL Rewrite tool is installed on your WorkflowGen server.
Create or update the web.config file in your website's root folder (e.g. DRIVE:\inetpub\wwwroot\web.config).
Warning: This is not the same web.config file as the main WorkflowGen web.config file (located in DRIVE:\inetpub\wwroot\wfgen\web.config).

Define the redirection rule node as shown below (configuration / system.webServer / <rewrite> / <rules> / <rule>):

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="Root to wfgen" stopProcessing="true">
                    <match url="^$" />
                    <action type="Redirect" url="/wfgen/" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

IIS URL Rewrite
Visual C++ Redistributable
Note: This library is required if you encounter the error The specified module could not be found regarding the edge and edge-js libraries when accessing the /wfgen/graphql or/wfgen/hooksweb apps.

Note: After enabling GraphQL and incoming webhooks, the WorkflowGen DLLs will be in use by Node.js, so they will be locked from being updated. In order to update the DLLs, it is necessary to stop IIS.

Enabling WorkflowGen GraphQL

In IIS, convert /wfgen/graphql to an application with a .NET 4 application pool (integrated pipeline).
Configure the GraphQL application authentication mode:
- For Windows or Basic authentication: Enable Basic authentication.
- For WorkflowGen Applicative authentication:
  - Make sure the /wfgen web application already has WorkflowGen Applicative authentication enabled.
  - Enable Anonymous authentication.

Enabling WorkflowGen incoming webhooks

In IIS, convert /wfgen/hooks to an application with a .NET 4 application pool (integrated pipeline), and configure the hook application in Anonymous authentication mode.

If your WorkflowGen is configured to use WorkflowGen Applicative authentication or a custom authentication, you must remove the authentication module from the /hooks/web.config file:

For WorkflowGen Applicative authentication:

<system.webServer>
    <modules>
        <remove name="ApplicationSecurityAuthenticationModule" />
    </modules>
</system.webServer>

For Custom authentication:

<system.webServer>
    <modules>
        <remove name="MyCustomAuthModule" />
    </modules>
</system.webServer>

WorkflowGen Windows services

WorkflowGen engine service

Automatic task execution (e.g. overdue exceptions and notifications management) is provided by this Windows service. This service is installed by the setup InstallShield Wizard and is started automatically after installation. (Refer to WorkflowGen Windows Services installation if the manual installation procedure was used.)

If errors occurred while the service is running, those errors will appear in the Event Viewer (source: WorkflowGenEngineService) accessible in the Windows Administrative Tools. All the messages related to this service will be displayed in the Windows Logs / Application section.

To manage this Windows service execution, open Administrative Tools / Services, then select and open WorkflowGen Engine (WorkflowGenEngineService).

WorkflowGen directory synchronization service

The automatic users and groups synchronization is provided by this Windows service, which is installed by the setup InstallShield Wizard and is started automatically after installation. (Refer to WorkflowGen Windows Services installation if the manual installation procedure was used.)

If errors occurred while the service is running, those errors will appear in the Event Viewer (source: WorkflowGenDirSyncService) accessible in Windows Administrative Tools. All messages related to this service will be displayed in the Windows Logs / Application section.

To manage this Windows service execution, open Administrative Tools / Services, then select and open WorkflowGen Directory Sync (WorkflowGenDirSyncService).

License activation

Overview

You must have a trial, Developer, or Enterprise license to activate WorkflowGen.

You must have a serial number to activate the Developer and Enterprise versions of WorkflowGen. If you do not have one, contact your vendor.

How to activate WorkflowGen

Install the license file

Remove all current .lic files from the DRIVE:\Inetpub\wwwroot\wfgen\bin folder.
Copy your .lic file to the DRIVE:\Inetpub\wwwroot\wfgen\bin folder.
Make sure the license file inherits the security settings.

Add the serial number to the web.config file

For the Developer and Enterprise editions of WorkflowGen, you must edit the "web.config" file located in the DRIVE:\Inetpub\wwwroot\wfgen folder.

Edit the "\Inetpub\wwwroot\wfgen\web.config" file.
Set your serial number as the value of the "ApplicationSerialNumber" parameter.

License per user

If you have a license per user, you cannot exceed the maximum number of users supported by your license, otherwise you will receive an error message when you try to launch a new request. However, user management will still be accessible.

If you want to import several users from your enterprise directory (Active Directory, LDAP, etc.), and since only active users are considered, you can choose between the following cases:

If your enterprise directory has fewer users than the maximum number of users supported by your WorkflowGen license, then you can import all of your users with the option New user default status set to Active.
If your enterprise directory has more users than the maximum number of users supported by your WorkflowGen license, then you should import all your users with New user default status set to Inactive and set the Self activation option as follows:
- If you want to manually activate users authorized to use WorkflowGen, uncheck the Self activation option. A user will be able to access WorkflowGen once you activate their account from the Administration Module.
- If you don’t want to worry about account activation, keep the Self activation option checked. New users connecting for the first time will be activated until the maximum number of users supported by your WorkflowGen license is reached.

Tests

Web app addresses

Check the following URLs with "wfgen_admin" user account:

User Portal: http://[yoursite]/wfgen
Administration Module: http://[yoursite]/wfgen/admin

If you are unable to log in, verify the web.config file in the root folder of the WorkflowGen application (usually DRIVE:\Inetpub\wwwroot\wfgen) and validate that the MainDbSource connection string contains the correct database connection information including server, database name, user, and password.

Test sample processes

You can create processes using the list of built-in process samples.

Additional configurations

You can change the security configuration (such as the authentication method) by following the instructions in the Security section.

Notes

Not all of the required configuration parameters of WorkflowGen are defined in this setup. It is recommended to update all other parameters in the Configuration panel in the WorkflowGen Administration Module after this setup. For more information, see the WorkflowGen Administration Module Reference Guide.
You can configure the time zone and language of new users through the Configuration panel in the Administration Module. You can also access the Configuration panel directly through the URL "http://[yoursite]/wfgen/admin/Config.aspx" once the setup is complete and the website is running.
The New User Time Zone settings can be changed on the General tab in the Configuration panel.
The New User Default Language can be changed on the Administration tab in the Configuration panel.
