If you use Enterprise Edition on your Oracle Database Appliance environment, and if you don’t have unlimited licences, you probably lowered the CPU cores available on each server to dispatch your licences accross your environment. This operation is normally done after deploying your ODAs, and this number of cores could eventually be increased if you need more and if you buy additional licences later. For most of us, the CPU core configuration will stay in its initial setup. But patching your ODA can enable back all the cores on your server, without any warning. Your configuration will then no more comply with your licences, and you may not even notice.<\/p>\n\n\n\n
I recently patched several ODAs X8-2M from 19.11 to 19.14. After solving issues described in the pre-patch report, I was able to apply the system patch without any problem.<\/p>\n\n\n\n

This will not work if you only have 2 cores configured on your ODA. You will then need to increase to 4 cores, and decrease to 2 cores. This can be a problem as this temporary increase can be detected and it’s not allowed. I would recommend opening a Service Request on My Oracle Support. You’re not supposed to move CPU cores’ configuration if it’s not related to licences upgrade.<\/p>\n\n\n\n
Conclusion<\/h2>\n\n\n\n
I don’t know if this problem is specific to this environment or if it’s more widespread. But you should add another post-patch check when applying a patch on your ODA: check with lscpu if the number of enabled cores matches your odacli configuration.<\/p>\n","protected":false},"excerpt":{"rendered":"
