I use DB2 on IBM Cloud. I got a message:
Unable to allocate new pages in table space "XXXXX"
May I know what's the table space for free plan and Flex plan? How to expand the space?
If it's Db2 on Cloud's free plan, your tablespace would be <username>space1
.
For the free version you are limited to that one tablespace and cannot increase it yourself.
Flex is a different story where you can increase it through a management page.
