Hello
BR0253E errno 2: No such file or directory
ls -la /oracle/SM3/112_64/dbs/initSM3.sap
If the file is not present there then check in the 10G Oracle location if this system was upgraded from 10G.
ls -la /oracle/SM3/102_64/dbs/initSM3.sap
If the file is there then copy to the missing location.
Good Luck
RB
