What is the IR_ready used for?

Hello U_32ee3f13-cc7d-48d2-9499-d921971890b6,

I think, the Database "IS_Ready" will be created during the installation of
the IS.
The files "IS_Ready.mdf" and "IS_Ready_log.LDF" are located in the folder
"C:\Program Files (x86)\Microsoft SQL Server\MSSQL10_50.WINCC\MSSQL\DATA".
If you can find the files the, you can try to attach the database
in the Microsoft SQL Server Management Studio, via right mouseclick on the
folder "Databases" and select "Attach..." in the context-menu.

Dear Sir,

May I know what is the IR_ready used for?

It is a linking file or pusher application between WinCC and SQL server?

Recently, I get the windows information log about this file is failed.

” failed to open the explicitly specified database "is ready". [ client: <local machine>] “

 byI already reboot the server, but this log is continuously happen

Hello WY.,

the WinCC stations and the PCS 7 Operator Stations (OS) need the "Information Server Ready"
(IS-Ready) component for communication with the Information Server.
IS-Ready is always installed as an option when you install one of the following products:
•Process Historian
•PCS 7
•WinCC V7

And the "IS-Ready"-database is a part of this component,
for more information see manual:

"Information Server 2014 SP3"
"Installing the Information Server Ready component"

 Thanks your information. 

Attached the SQL Server A manager capture.

I found the "IS_READY" is missing and the windows system also logged with:
"failed to open the explicitly specified database "is ready". [ client: <local machine>]"

Moreover, there are TWO SQL file named as a random code and number

As comparing with my Server B, the "IS_Ready" is existed and without the TWO
SQL file which is a lots of different number and word. 

As the system condition, both servers are running in redundancy mode and both logging function are in normal condition.

However, should I add back the "IS_Ready" to the Server A?  Should I handle the others TWO SQL file in the capture? How is the procedure to do this and need stop the WinCC Runtime?
