but I want to know 4th point of soa version4th point represents the version of bundled patch (if any applied). I am not sure if you can find it anywhere explicitly but one easy way to figure out this number is by getting the "opatch lsinventory" output and find the patch numbers which are applied in your installation. Then using patch numbers, you may search on support portal whether any of them belongs to any bundled patch. And if any of them belongs to any bundled patch then from the patch name itself you can figure out it's version. The same will the 4th point of your SOA installation version.
