Migrating Oracle Applications 11i to RAC 10g

Today I was trying to complete the migration of Oracle Application 11i to RAC 10g and while running command rconfig to Convert Database to RAC I got disconnected from the network so I tried to start the database from the new oracle home so I could run the command again and this time I got the following error message

ORA-27504: IPC error creating OSD context
ORA-27300: OS system dependent operation:sendmsg failed with status: 12
ORA-27301: OS failure message: Cannot allocate memory
ORA-27302: failure occurred at: sskgxpsnd1


After continues searching on metalink & troubleshooting I finally found a way to start the database from the new home and the steps I followed are


2. Turn RAC option off:
- Log in as "oracle"
- cd $ORACLE_HOME/rdbms/lib
- make -f ins_rdbms.mk rac_off
- make -f ins_rdbms.mk ioracle
