Grid Control Agent 10.2.0.5 Fails to Monitor 9.2.0.x Databases with ORA-3113/ORA-7445

I got the error after installed the agent.

WARN  vpxoci: Login 0x3549830 failed, error=ORA-03113

OS: Windows 200
DB: Oracle 9.2.0.6
GC Agent 10.2.0.5


Solution:
There are two solutions to this issue:
A. Upgrade the target database to a version which is covered by Premier Support or apply the 9.2.0.8 terminal patch set to the target database. The recommended solution is to upgrade the database.


B. If you cannot upgrade your target database to 9.2.0.8, there is also a fix on the Agent side:
Apply Agent PSU2 Patch 9162498 (Unix) / Patch 9223116 (Windows) on top of the 10.2.0.5 Agent. Please check Note 986539.1 for more details about PSU2.
To activate the fix, add the parameter AvoidOCIPing=1 in $AGENT_HOME/sysman/config/emd.properties and restart the Agent. This parameter is not there by default: it is a toggle to activate the bug fix for this particular issue. The default value is 0, which means that the fix is not activated.
OK, I use Patch 9223116

I use opatch to apply this, second error came to me.

C:\OracleHomes\agent10g\OPatch>opatch
Oracle Home is not set. OPatch cannot proceed!

OPatch failed with error code = 1

It's ORACLE_HOME missing, OK. 

set ORACLE_HOME=C:\OracleHomes\agent10g

Java could not be located. OPatch cannot proceed! 

OPatch failed with error code = 1 

It's mean OPATCH can't find java.

so use this command

opatch lsinventory –jre %ORACLE_HOME%\jdk 

Finally, my agent can work perfectly.
