I have installed and configure BW system in my SAP Landscape but for doing some migration i wanted to uninstall the BW system which is distributed. So i have uninstalled the Central instance but when i’m trying to uninstall the DB instance i got the below error :
An error occurred while processing option SAP NetWeaver 7.0 including Enhancement Package 2 > Software Life-Cycle Options > Uninstall > Uninstall – System / Standalone Engine / Optional Standalone Unit( Last error reported by the step: Assertion failed: OraDbStateManager3.readFromDb: ‘SELECT STATUS FROM V$INSTANCE’ did not match /^\s*(\S+)\s*$/gNaNOPEN MIGRATE’). You can now:
Choose Retry to repeat the current step.
Choose Log Files to get more information about the error.
Stop the option and continue later.
Log files are written to /tmp/sapinst_instdir/NW702/LM/UNINSTALL/AS.
So when logged in to DB with oraSID user and i checked the Oracle Database status, it was running so i Shutdown the Database and retry the uninstallation process then the Database instance uninstalled successfully.
