Kernel parameters are incorrect after upgrading / patching the ODA.
The Kernel parameters are now the same as the factory default even though changes were made to best match available resources after a Memory / DIMM upgrade.
This may lead to error messages stating that resources may not be sufficient or are incorrect to startup database, processes or applications.
- ODA physical memory upgrade on the ODA beyond the base size ( e.g. 256g)
- OS Kernel parameters changed to use the improved memory available
- Patch bundle / Upgrade applied
