When using Appian, your system must meet the following minimum requirements.
This table lists the supported platforms for servers that host Appian.
|Linux (Reference Platforms)||Windows|
|Red Hat Enterprise Linux||Windows Server 2012|
|CentOS||Windows Server 2008|
The table below lists the supported application servers.
|Supported Application Servers||Supported JDK||Comments|
|JBoss Enterprise Application Platform 6.4 (6.4.14 or later)||Oracle Java JDK 1.8.0_x (update 92 or later)||The latest minor version of JBoss EAP 6.4.x is required for production and recommended for non-production.|
|WebLogic Server 12c R2 (12.2.1.x)||Oracle Java JDK 1.8.0_x (update 92 or later)||WebLogic Server 12c R2 patch version 220.127.116.11 or later is required in order to avoid a classloader bug that can prevent system startup.|
Note: Due to the potential for unintended interactions and resource contention when deploying multiple enterprise application archives (EARs), Appian requires the Appian EAR be the only application (EAR or WAR) deployed on the production application server.
The table below describes the recommended minimum physical system requirements. The RAM and hard disk requirements are in addition to any system memory used by other applications and by the operating system.
|Systems||RAM (GB)||Hard Disk (GB)||Processor Cores or CPUs|
|Client workstations||2||Web Browser||1|
|Appian Designer client workstations||4||Web Browser||1|
|Machines hosting the application server||4||50||2|
|Machines hosting Appian engines||4||50||2|
Your actual requirements may vary. Given that Appian utilizes an in-memory database, use the sizing script to help project the RAM that will be required for your installation.
For customers who wish to run Appian from cloud infrastructure as a service, Appian will run on any that support the operating systems, application servers, and minimum hardware requirements as listed in this article.
The following major providers of cloud infrastructure as a service are known to be compatible with Appian:
|MySQL 5.7.x (on latest patch) with InnoDB engine||Connector/J 5.1.x (on latest patch)|
|MySQL 5.6.x with InnoDB engine (deprecated)||Connector/J 5.1.41 (or later)|
|Oracle 12c R1||Oracle Thin JDBC Driver for 12c R1
(with patch for Oracle bug 19632480)
|Oracle 11g R2||Oracle Thin JDBC Driver for 11g R2|
|Microsoft SQL Server 2014||Microsoft JDBC SQL Server Driver 4.2 (or later)|
|Microsoft SQL Server 2012||Microsoft JDBC SQL Server Driver 4.2 (or later)|
|Microsoft SQL Server 2008||Microsoft JDBC SQL Server Driver 2.0 and 4.2 (or later)|
|IBM DB2 UDB v9.7 for Linux, UNIX, and Windows||IBM DB2 JDBC Driver version 4.9.78|
In addition to these databases, other databases not listed here are also supported for use with the Query Database Smart Service, as long as the database provides a JDBC compliant database driver.
Note: Appian recommends a round-trip time for TCP communications between the application server and database of less than 10 milliseconds with an upper bound of 25 milliseconds for acceptable performance. Network latency outside of these bounds will result in degraded system performance.
The supported Web browsers are listed in the table below. Use the Appian for Mobile Devices application for iOS and Android instead of mobile browsers. See Mobile Devices for more information.
Web browsers must allow cookies. If a user's browser is not configured to allow cookies, then Appian displays an alert stating that cookies must be enabled in order to log in.
|Microsoft Edge||Microsoft Edge is only supported on Windows 10 operating systems.|
|Microsoft Internet Explorer 11||
Microsoft Internet Explorer 11 is supported on Windows operating systems.
Microsoft Internet Explorer 11 is supported on Windows 8.x tablet.
Running Internet Explorer in Enterprise or Document Mode to emulate older browser versions is not supported.
|Mozilla Firefox||Mozilla Firefox updates automatically. Appian supports the most recent stable version of Mozilla Firefox.|
|Google Chrome||Google Chrome updates automatically. Appian supports the most recent stable version of Google Chrome.|
|Apple Safari||Safari is only supported on Mac operating systems.|
Note: Appian does not support browsers that are no longer supported by their vendor. Use the latest supported browser version and always apply all available security updates.
Web browsers for Appian Cloud users should be configured to allow TLS version 1.1 and/or 1.2 as Appian Cloud sites will drop support for TLS 1.0 in a future release. See KB-1064 for more detail.
The table below lists browser compatibility by feature. Certain features in Appian, such as the Process Modeler, have their own browser configuration requirements. See Web Browser Configuration for more information.
|Feature||Edge||Internet Explorer 11||Internet Explorer 11 (tablet)||Mozilla Firefox||Google Chrome||Apple Safari|
|Appian Designer /design||Yes||Yes||No||Yes||Yes||Yes|
All supported versions of the Appian mobile app are listed in the Product Release History.
The latest version of the Appian mobile app is always backward-compatible with previous Appian versions, so we encourage you to update to take advantage of new features and enhancements.
Web parts for news, tasks, and actions are supported for Microsoft SharePoint 2013 using the Appian for SharePoint 2013 module.
