I am receiving the following error when attempting to run the sdelayer command with the load_only_io switch.
Error: Underlying DBMS error (-51).
Error: Setting Layer to LOAD-ONLY mode.
ORACLE error: code is 3114, func is OOPEN
ORA-03114: not connected to ORACLE

Can anyone give me some direction on what could be causing the error?

Thanks.
