Good Day
Refer to sap note Note 1341277 - Inst.NetWeaver 7.0 EHP2/ Business Suite 7i2010 - UNIX/Oracle
Error "role ORA_SID is not created yet" during (A)SCS instance installation
Symptom:
You are running installation option "ASCS Instance" or "SCS Instance" and get the following error message: "role ORA_SID is not created yet"
Solution:
Restart SAPinst using command line option SAPINST_SKIP_ERRORSTEP=true. On the "What do you want to do" screen, choose "Continue with the old option".
Why are you asking him to check the SAP Note again when he very well knows that note ?
Did you read the initial post with the actions he had taken before coming here ?
He already mentioned this note in the message and it looks like you dont read before replying.
Cheers
