- From version 16.1.0, the maximum value of sys db provision.extramb is 4096 MB, reduced from 8192 MB. It will be automatically set to 4096 during the upgrade if it has a higher setting - A prior fix was done in ID1589269, which fixed it in 17.1.3.1, but the issue was reintroduced in 17.1.3.2
- It is extremely rare to need values of provision.extramb above 4096 MB - If the value of sys db provision.extramb is 4096 or less before upgrading, then there will be no impact post-upgrade. After the upgrade, it is not possible to increase the value above 4096
