This little beastie gets installed when you run opatch now. Most of you have no need whatsoever for it. So let's get rid of it :
Metalink Note 369111.1 has the answer but in True Oracle Fashion they didn't test it properly on all platforms
They did it on Linux, but the answer they give on Windows fails for me [ they wrote up something for Windows in cscript vbs ]
however it works quite nicely if you do
deploypackages -d %ORACLE_HOME%\ccr\inventory\core.jar
And no more OCM.
