So what's missing from Srvany?
The Windows NT Resource Kit introduced the Srvany.exe command-line utility,
which can be used to start any Windows NT/2000/2003 application as a service.
Srvany is basic and functional, and its price tag (free) makes it a fine choice for many environments.
However, most computer professionals will find that it is missing some important benefits
when compared to AlwaysUp:
- No Windows 8/7 or Windows 2012/2008 Server support: Srvany.exe was developed for Windows NT back in the 1990's and hasn't really changed since then.
Srvany doesn't know about Remote Desktop,
Session 0 isolation,
or anything else that has happened with Windows Services in the past decade.
- No easy installation: As described in Microsoft's Srvany documentation,
"How To Create a User-Defined Service",
installing your application with Srvany involves running
the companion Instsrv utility from the MS-DOS command prompt and manually editing the registry (at your own risk!). On the other hand, AlwaysUp is simply point-and-click.
(See the 1-minute demo showing how to setup an application with AlwaysUp.)
- No restarting / 100% uptime: If your application terminates unexpectedly, Srvany will not revive it. In fact, Srvany may continue to run, giving the false impression that your application is alive and well!
- Doesn't stop your application: Stopping your Srvany service from the services control panel will terminate the srvany.exe process but Srvany will not close your application!
This can lead to great confusion as starting the service again will launch a second copy of your application. AlwaysUp will stop your application (and all its sub-processes) as expected.
- No application monitoring: Srvany does not monitor your application at all -- it simply starts it, once. AlwaysUp can restart your application if it hogs the CPU, uses too much memory, or hangs.
- No logging / Can fail silently: If Srvany fails to start your application, it doesn't write anything to the Windows Event Logs, a log file, or anywhere else. These scenarios can be very difficult to debug!
AlwaysUp writes all its activities to the Event Logs.
- May not show your application's windows / taskbar-icon / GUI: Srvany may not be able to show your application's windows or task-tray icons. Several restrictions and caveats apply (for example, you must run in the system account,
on the console session, no RDP, etc.).
AlwaysUp can often get around those restrictions.
- No email alerts: Srvany can not email you when your program fails and has to be restarted. AlwaysUp will do that, and send you daily/weekly reports summarizing your application's activities.
- No scheduled restarts: For example, you can instruct AlwaysUp to restart your application (or reboot your computer) at 3 AM every day to cure memory leaks, etc. Not available with Srvany.exe.
- No network drive support: Network drives mapped by your service account are not available when using Srvany. AlwaysUp can automatically restore your network drives.
- No extensibility: With AlwaysUp, you can plug in your own failure-detection batch file/program to let AlwaysUp know that
your application has failed and needs to be restarted. Similarly, AlwaysUp allows you to plug in your own automation program,
to auto-fill dialogs and close popups coming from your application. Srvany is not extensible.
- No reports: Srvany doesn't feature reporting of any kind, but AlwaysUp can show you how your application has been performing (CPU, memory, uptime).
- No web service: With AlwaysUp, you can control and interrogate your service using our free add-on, AlwaysUp Web Service.
But perhaps most important of all, Srvany is not supported under any Microsoft standard support program or service.
It was last released in 2003.
