Good Afternoon:
I know it's been a couple years. This came up for us just today. Take a look at $ORACLE_HOME/dbs for the init<SID>.ora file. SAP prefers that it contains just the one line pointing to the spfile
spfile = (+ASM_LOCATION/spfile<SID>.ora)
One of us did a "create pfile from spfile" and it did what we asked. It created a hundred parameters and put them into the init file in $ORACLE_HOME/dbs
Fixed by re-creating the one-lined edition pointing to the spfile.
Thx
Tony
