while installing the oracle agent 10.2.0.5 agent and rediscovering I received several errors in the instances monitored :
< ORA-00603: ORACLE server session terminated by fatal error
< ORA-27504: IPC error creating OSD context
< ORA-27300: OS system dependent operation:IPC init failed with status: 65

further investigation pointed me to metalink notes
Ora-00603 When Invoking Sqlplus Via Grid Control OS Command Job (Doc ID 1327675.1)
ORA-7445 [KSXPSIGOSDERR()+252] ERROR IN A RAC DATABASE (Doc ID 984963.1)
I basically adapted the emctl script of the agent and just added the following:
LD_LIBRARY_PATH_64=$ORACLE_HOME/lib:$LD_LIBRARY_PATH_64
I did this straight after this section of the script
