To prevent Integration Server from shutting down as a service on Windows after you log off, add -I to the startup.bat file.
When you run Integration Server as a service on Windows, Oracle recommends you use -I.
In the startup.bat file, to prevent Integration Server from shutting down as a service, add -I after "C:\Oracle\Middleware\EPMSystem11R1\products\Essbase\eis\server\bin\olapisvr.exe". For example:
"C:\Oracle\Middleware\EPMSystem11R1\products\Essbase\eis\server\bin\olapisvr.exe" -I
