Creating a windows service for a managed server in OBIEE 11.1.1.6

Create a text file with the contents as below, the assumption here is that you have a middleware home of D:\OBIEE11G - set yours appropriately and fill in the servername in <myserver>.

SETLOCAL
set DOMAIN_NAME=bi_server1
set USERDOMAIN_HOME=D:\OBIEE11G\user_projects\domains\bifoundation_domain
set SERVER_NAME=bi_server1
set PRODUCTION_MODE=true
set ADMIN_URL=http://<myserver>:7001
cd %USERDOMAIN_HOME%
call %USERDOMAIN_HOME%\bin\setDomainEnv.cmd
call "D:\OBIEE11G\wlserver_10.3\server\bin\installSvc.cmd"
ENDLOCAL

and name the file something like "installManServer.cmd"

Assuming that you have created an AdminServer service and set the Java Memory configuration then you are nearly home and dry.

Refer to http://docs.oracle.com/cd/E14571_01/web.1111/e13708/winservice.htm#i1188099

especially the part on delay (-delay:delay_milliseconds) and depend (-depend:"beasvc Adminserver_Adminserver")
for example -delay:300000 will delay for 5 minutes

And in your  WL_HOME\server\bin\installSvc.cmd script edit in the delay and/or depend parameters.
Also remember to change your logfile destination, you don't want Adminserver and managed service in the same logfile, trust me, it gets very confusing.

This should give you a final line in the I=installSvc.cmd that looks something like

"%WL_HOME%\server\bin\beasvc" -install
-svcname:"%DOMAIN_NAME%_%SERVER_NAME%"
-delay:300000
-depend:"beasvc Adminserver_Adminserver"
-javahome:"%JAVA_HOME%" -execdir:"%USERDOMAIN_HOME%"
-extrapath:"%WL_HOME%\server\bin" -password:"%WLS_PW%"
-log:"D:\OBIEE11G\user_projects\domains\bifoundation_domain\servers\bi_server1\bi_server1-stdout.txt"
-cmdline:%CMDLINE%

This also works for 11.1.1.7
