You can try this using EmergencyId mode. Stop IRIS and start with the parameter:

Linux

iris start IRIS EmergencyId=user,password

Windows

iris start IRIS /EmergencyId=user,password

User and password can be anything. This will be used for login.

Once logged in as this user by the terminal, you can use the ^SECURITY routine in the %SYS namespace to change the password of _SYSTEM.

EmergencyId Mode

^SECURITY

You have to include a slash before EmergencyId :

iris start iris /EmergencyId=userA,pwB

Also, make sure that 'iris' is indeed your instance name (use 'iris all' to show all instances)

You have to include a slash before EmergencyId :

It depends on OS. In Linux there's no slash. Windows is with slash.

Now getting below error after specifying right instance name:

Startup failed: (22) Instance properties definition file does not exist or is inaccessable: EmergencyID=user,password Configuration IRISHealth.

Can you show the output of 'iris all' ?

Which is your OS ?

Can you try again with the slash (since it is windows, you have to use the slash) :
iris start irishealth /EmergencyId=user,password

As @Danny Wijnschenk said, on Windows it needs to be /EmergencyId=.

There are a few more instructions in the Documentation, like "Start a command prompt, running it as an administrator", etc.

Muhammad,

How can I disable the recovery function ? Also I should add that I need to restore it also, can I rename that routine to something else ?

Thanks.

What do you mean? Why do you want to disable it and rename?

Command line pretty easy to follow. However after running it I am presented with a dialogue box. In the message log it states
9/10/25-10:18:02:616 ( 3612) 3 irisctl.dll (error during startup):(289) IRIS failed to start. IRIS Control Process terminated abnormally (exit code = 0).
09/10/25-10:17:57:299 (18812) 2 [Generic.Event] Unable to allocate shared memory minimum of 146MB

The last message/error is pretty clear:
Unable to allocate shared memory minimum of 146MB

Although it seems strange to me that a modern system is not able to allocate 146MB of memory!

Can you try to reboot the system?
