Hi Experts!
OS: WS 2012 Standard R2
System: SAP ERP 6.0
Database: Oracle12c
I have a finished a BRBACKUP(online consistent) with RC 5 so I investigate why it happens and i discover that the database is down and try to start it up again. Sqlplus /nolog > conn / as sysdba then I have encounter an error ORA-00020: maximum number of processes (300) exceeded . then i search how to fix it and i found out that you need set its parameter, the case is I need to logon as sysdba first before adjusting the parameter which is oracle not allowing me. then i tried to restart the server after the reboot i have successfully connected as sysdba but after the startup a new error occur and ORA-03113: end-of-file on communication channel, and try to start it up again and throws me a new error SP2-0642: SQL*Plus internal error state 2133, context 3114:0:0 Unsafe to proceed, ORA-03114: not connected to ORACLE.
[ i think restarting the server is my wrong move ] :((
I tried to run r3trans -d then its says:
This is r3trans version 6.24 (release 721 - 14.10.14 - 20:14:08).
unicode enabled version

Please help!
