ArcGIS Mission Server supports multiple-machine sites starting at 10.8.1.
At the 10.8 release, only single-machine sites were supported.
Multiple-machine ArcGIS Mission Serversites allow you to support more active members of a mission. If you have many active users, or if your single machine's resources are inadequate for your users' needs, expanding to a multiple-machine site could be beneficial.
All machines in a ArcGIS Mission Server site must have the version and same license file. On the first machine you set up, you'll need to create a ArcGIS Mission Server site. You can then join any additional ArcGIS Mission Server machines to the site.
Unlike other ArcGIS Server roles, ArcGIS Mission Server does not support adding additional machines to a site from the first machine. You must access each machine in turn and join them to the site procedurally, using either the ArcGIS Mission Server configuration wizard or the joinSite command line utility.
Before you install
When you first create a ArcGIS Mission Server site, you specify locations for the configuration store and server directories. In a multiple-machine site, you must share the configuration store and server directories so that the other machines can access them. Each machine that joins the site must be granted read and write permissions to these shared locations
Install and configure a multiple machine site
When setting up a multiple-machine ArcGIS Mission Server site, additional steps are required.
- Review the system requirements for ArcGIS Mission Server for each machine. Adjust the firewalls to open port 20443 for communication from each machine in your ArcGIS Mission Server deployment.
The installed version of ArcGIS Mission Server and its license file must be the same on each machine. Enter the same ArcGIS Mission Server run-as account during each installation. It's recommended that you use a domain or Active Directory account, but if you choose a local account, it needs to exist on each machine with an identical name and password combination. Keep in mind that the account you specify does not have to be part of the Administrators group.
- Create and share two directories on your network. One should be for the configuration store and the other for the server directories. Grant read and write permissions for these two directories to the ArcGIS Mission Server account on each machine (make sure to do this on both the Sharing tab and the Security tab of Windows Explorer).
Shared network directories that are hidden or use special characters (such as $) are not supported by ArcGIS Mission Server.
- Even if the directories reside on the same machine that you will use when creating the site, you must still manually create and share the directories and reference them through a network (UNC) path.
- If the ArcGIS Mission Server account does not exist on the machine (in the case where you put the configuration store and server directories on a file server), you need to create the ArcGIS Mission Server account using the same name and password that you used in all the other machines in your deployment.
- If you are using a group managed service account (gMSA) for the ArcGIS Mission Server account, you must allow service accounts to have full control permissions in the Sharing and Security tabs. From the Permissions editor, click Add, and open the Object Types. dialog box. Check the box for Service Accounts.
- From one of your machines, create a ArcGIS Mission Serversite. Ensure the paths for the server and configuration store directories are specified during creation.
- Once the previous steps have been completed, you can join each additional machine to the site you've created using a configuration wizard. If you prefer to join the site from the command line, see step 5.
- From the first additional machine, open the ArcGIS Mission Server Configuration Wizard.
- Review and follow the instructions provided in the wizard, and then click Continue.
- Click Join Existing Site.
- Enter the site URL and credentials for your ArcGIS Mission Server site as created in step 3.
- Repeat steps a through d for each additional machine you want to join to the site.
- As an alternative to using the configuration wizard, you can join the machine to the site using a command line utility as follows.
- Ensure you're logged in to the machine with the ArcGIS Mission Server account.
- Open a command prompt and run the utility, which is located at <ArcGIS Mission Server install directory>\tools\joinsite\joinsite.bat. The following are the command line parameters for the utility:
-u or --username
The user name of the primary site administrator.
The user name cannot contain these characters: \/:*?|<>
-p or --password
The password for the primary site administrator.
The password cannot contain these characters: \/:*?|<>
-f or --file
The configuration store connection file for the joinsite utility.
-s or --siteUrl
The URL of the existing ArcGIS Mission Server site to join, in the format https://missionserver.domain.com:20443/arcgis/admin.
-h or --help
Displays command line help and exits.
An example command for the utility:
<ArcGIS Mission Server install directory>\tools\joinsite\joinsite.bat -u missionadmin -p my.Password3 -s https://missionserver.domain.com:20443/arcgis/admin
If the account credentials and site URL are entered correctly, the utility will join the machine to the ArcGIS Mission Server site. Repeat this step for each additional machine.
Once all the machines are joined to the site, the remaining setup process is the same as for single-machine sites. Proceed to install and configure ArcGIS Web Adaptor with your site. You will then configure your site with your ArcGIS Enterprise portal.
