SAP Note 11291 - Error BR068E SAP still active during offline backup.

Symptom

BRBACKUP reports
BR068E SAP is running or SAPR3 is connected - database shutdown
impossible
during offline backup. R/3 System was stopped using "stopsap R3".

Cause and prerequisites

An Oracle user, sapr3, is still logged on to the database.

Solution
1. A user in the system used Oracle tools (sqldba or sqlplus) to
log on to the database as sapr3.
You can check this using the following command (§ = pipe character):
ps -ef § grep sql (=>is sqlplus or sqldba displayed ?)
2. Problem shutting down or operating R/3. Under certain constellations
ownerless Oracle shadow processes may remain. Use the following
procedure:
ps -ef § grep § grep oracle
Once R/3 has been shut down, if a process with the name oracle
P:... is still found, check the parent process number (3rd column
of the PS list). If this number is 1, this is a ownerless process.
Use kill -2 to eliminate the process.
